Routers, hubs, and ehternet printing

We have three Macs (two with Tiger and one with Panther) sharing our cable modem and a Brother laser printer via a router (one WAN port and four LAN ports) and CAT5 cabling. This current network config is working fine.
Yesterday we bought a network-ready multi-function inkjet unit (HP6280) and I want to share it, too, but I'm out of ports. Rather than buy a router with more ports right now, I'm thinking of putting an unused ethernet hub on one LAN port on the router and having the two printers on the hub.
Any thoughts on whether this is an acceptable ethernet arrangement before I try it? I spent a large chunk of yesterday on the Internet trying to find out if this would work but am getting mixed results. Nothings so far says, "No," but then nothing is saying "oh yeah, slam-dunk success" either.
BTW, we have no wireless-equipped gear at the moment, but may get a Mac Book Pro after the MacWorld announcements in January. That's the major reason I'm holding off getting another router today--I'll need one later with both wired and wireless capability.
Thanks in advance,
Allan

Thanks, Kappy!
The hub indeed has an uplink port--I only need remember which switch setting is which! The switch isn't labeled and I have no idea where the instructions are (Old Farallon hub--now out of the wired business). Trial and error should work; I can;t imagine that it would break anything.
The new MF is now doing its initial set-up routine and I'll try it without the hub (or the laser) first to see if all is "George" with the unit.
Onward and upward!

Bt Infinity hub and USB printing

Hi all.
I have recently got BT Infinity and the new homehub required. I am liking the service though the new hub does not allow me to plug a printer into the USB port on the back.
I know the homehub does not officially support printing, but my previous homehub (version 2) allowed me to plug a printer into the usb port and use 192.168.1.253 as an ip address.
When I plug the same printer into the new infinity hub the homehub page says that nothing is connected to the usb port. If I plug a flash drive into the port it is recognised straight away.
When I plugged my printer into the usb port of the old version 2 homehub the hub page recognised the printer was plugged into the usb port and even gave the name and model of the printer.
Has anything changed that for the infinity hub that would make adding a usb printer impossible? Does anyone else with infinity have a usb printer plugged into the back of their hub? If so how did you get it to work?
Any help/info on this matter would be grately appreciated.

Having the same issue.
What a shame I have to leave my old wireless router plugged in just so that I can use the shared printer.
Is there a reason this is disabled?

I can't print wirelessly using Airport Express. I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not.

I can't print wirelessly using Airport Express. I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not. I've tried several USB connectors, and several different ports on my USB hub; same result. I need to have the HP connected to the hub 'cause from there it's connected to our desktop Mac.

Hi,
I am currently replying to this as it shows in the iChat Community.
I have asked the Hosts to move it to Snow Leopard (you should not lose contact with it through any email links you get)
I also don't do Wirelss printing so I can't actaully help either.

Usb laser printing, HD's with integral hubs, and open doors to network?

Bought a N capable base station and an airport express this week as I have multiple minis and a macbook and wish to put my itunes onto a central drive and use wireless printing.
Spent an “interesting” evening last night setting up, and I seem to have worked out how to use itunes via aliases etc.
But – when I try to print, the dialogue box comes up, the laser printer (Samsung 2550) starts up, but fails to print.
My set up is as follows – Iomega 320gb mini HD (powered) plugged into the USB on the base station and then the laser and my inkjet plugged into the USB sockets on the HD (its one of those which has an integral USB and FW hub built in).
Now, as it was very late in the evening, I didn’t do any more trouble shooting, but am intrigued as to why the printer would not print. The log says that the print job has been completed, but nothing comes out. I disconnected the printers from the hd hub and then disconnected the HD. I then plugged the printer directly into the base station, but it still doesn’t work.
Annoyingly enough, the printer worked fine the previous night when I was using it with the usb on the airport express alone (hadn’t bought the base station at this point).
The computer(s) “see” the laser printer without difficulty, so I see no reason why it should not print using the base station.
One thing which occurs to me is to plug a powered USB hub into the base station, and then separately plug the HD and the Laser into sockets on this hub, rather than using the integral hub of the HD. Again, I cant see why this should be necessary but I’ll give it a try.
Any thoughts re this?
One Last Thing…
The main reason for buying the kit is to cover a “weak spot” in the house for wifi. Hence the idea was to connect my modem/router via Ethernet to the base station, and then use the airport express as a WDS to effectively re-broadcast the signal and hopefully provide maximum signal strength throughout the house.
My question is – having used the airport utility to do this, am I right in presuming that the airport express then becomes effectively “invisible” and hence when I use my mini in the weak spot to log onto a network via airport, I should only see the SSID of my main base station (although in reality I will be accessing it via the airport express). I think this must be right because when I added the airport express the signal strength in the weak area of the house went to the max.
My base station uses WAP protection but I don’t appear to have any protection set up on the airport express (which I realise is a router in its own right). Do I need to add protection to the airport express to prevent access to my overall network? In otherwords, is an unprotected airport express acting as a WDS, effectively an open back door to the network? Would a neighbour etc be able to pick up my network SSID being broadcast by the airport express and log onto that without the WAP password?
Finally what is the difference between the airport express being a remote or a relay station. I would have thought that to act as a network extender, it should be set to relay, but the default appears to be remote. The Apple help sections don’t appear to distinguish between functionality, merely state the options.
Any help/advice gratefully accepted
Airport extreme, mac minis

I then plugged the printer
directly into the base station, but it still doesn’t
work.
You need to get this to work first. Otherwise forget it to work with a Hub. Turn the printer on FIRST. Then turn on the base station.
One thing which occurs to me is to plug a powered USB
hub into the base station, and then separately plug
the HD and the Laser into sockets on this hub, rather
than using the integral hub of the HD. Again, I cant
see why this should be necessary but I’ll give it a
try.
Direct connection and powered USB Hub are the only supported configurations by Apple. I've had no problem with attaching up to 7 separate devices on a $20 powered hub. Having a "integrated hub" like you describe may theoretically work, but it is not the same thing as a separate hub.
My question is – having used the airport utility to
do this, am I right in presuming that the airport
express then becomes effectively “invisible” and
hence when I use my mini in the weak spot to log onto
a network via airport, I should only see the SSID of
my main base station (although in reality I will be
accessing it via the airport express).
If you use WDS or "extend" the network, all base stations will still broadcast the SSID.
My base station uses WAP protection
You must mean WEP or WPA. There is no WAP protection.
but I don’t
appear to have any protection set up on the airport
express (which I realize is a router in its own
right). Do I need to add protection to the airport
express to prevent access to my overall network? In
other words, is an unprotected airport express acting
as a WDS, effectively an open back door to the
network? Would a neighbor etc be able to pick up my
network SSID being broadcast by the airport express
and log onto that without the WAP password?
Yes, even if you turn SSID broadcast off, the SSID is broadcasted during the transactions and it will be easily detected using iStumbler. An yes you are letting a nice open back door for your neighbors.

Since changing over to a new BT hub my iPad mini will not recognise an Epson XP printer although this worked fine with Sky. Printer and iPad set up for new hub and independently recognise hub

Since changing over to a new BT home hub, my iPad mini does not recognise an Epson XP 305 air printer although system worked well on previous Sky hub. Both printer and iPad set up and recognise hub independently. Has anyone come across this problem?

Wireless and network printing transcript for Meet the Experts

On March 16th, HP hosted its first online chat event on wireless and network printing. Below is a transcript of that session.
I am in the process of planning the next chat event. I would love to hear what topics would interest you, what day of the week and time is best for you, and if you think an hour is too long.
So, if you get a minute, please let me know.
Here's the transcript:
SiobhanF-HP: Welcome! Cameron, Craig, David, and Jim are ready to tackle your questions.
SiobhanF-HP: Just to remind you if you want to ask a question, you must be a member of the HP Support Forums. If you want to join, go here https://passport2.hp.com/hppcf/createuser.do
nc256: Do I need a wireless router to hook up my wireless printer?
CameronL-HP: No, but most people will want to do it this way. You can use a feature called an ad hoc connection to avoid using a router, but it is only covered under an older standard that is slower and less secure. Also, without something to route traffic between the local network and the internet, you cannot get an internet connection. Using a wireless router makes setting up a wireless network easier, and it will generally make the network work better too.
jest1: I've seen some hardware in stores for a "print server" hardware device that attaches to a network. Is this something that I need in order to run a printer over a network?
CraigB--HP: Not if you have a printer that has a network connection built in. Many models of HP computers are ready to be connected directly to your wired or wireless network.
katiepage: How can I print when I am using a VPN?
DavidH-HP: VPN connections generally hide the rest of your home network to increase the security of the VPN connection. A printer on the network isn’t a security threat but the VPN doesn’t know that. It just hides everything just to be sure. That means that when a VPN is active you need some way to connect to the printer other than your home network. Bluetooth, USB, and even printing to a thumb drive and plugging that into the printer are all ways of getting your print job to the printer that don’t go through your home network.
SiobhanF-HP: If you have specific product questions, the more information you give us the better we will be able to help you. Getting your exact model number; any error messages; a description of your wireless network including what kind of security you have, what wireless-devices are connected to your network, and your IP address will go a long way to helping us answer your question.
MelissaP: Why would I want a wireless printer?
CraigB--HP: The main advantage of a wireless printer is the ability to place the printer somewhere in your home or office even if this is not near your router or computer.
Deltan: What is the maximum distance I can have between my router and my printer?
CameronL-HP: It does depend on your environment. Without interference about 25 feet. Walls and floors and other objects can reduce this. The types of walls are important. For example, mirrors and outdoor walls will greatly reduce the indoor range.
jest1: Is there a preferred wireless router type or brand for wireless printing compatibility? We are using a Linksys 802.11g router in my home.
JimB-HP: In general, any wireless-router from a name brand manufacturer that has been Wi-Fi certified is compatible with our printers (look for the Wi-Fi logo). We use Linksys in our lab with great success.
nc256: Are there any digital cameras that can send directly to an HP wireless printer for photo printing?
DavidH-HP: Many printers support a feature called Pictbridge. If the camera and printer both supports this feature, the camera can be plugged directly into the printer to print photos. Or are you asking about printing over a network connection?
KevinW: I keep hearing that you shouldn’t use default settings for a network. Why?
CraigB--HP: There are three reasons not use default settings: First, wireless-routers do not have any wireless security enabled by default. Second, you will be using a common network name in which case you may connect accidentally to your neighbor’s network. Third, your wireless-router is accessible by inadvertent guests who may change the configuration of your wireless-router without your knowledge or use your internet connection without your permission.
Bodie08: I have an HP Lan attached printer and Windows XP on my home network. Is there a known setting (Firewall/port/other) or patch to address the issue of hpqtra08.exe hanging on Windows XP Shutdown? A number of us in the forum have identified this issue. Thanks!
DavidH-HP: This problem has been seen in the past but there were attempts to address it. Have you checked to see if there is a later release of software available on the web? (hp.com)
ZhuLee3: How old is wireless printing technology? I noticed all the experts have around 20 years of experience with it, was there wireless 20 years ago?
JimB-HP: Wireless printing first appeared with the introduction of the 802.11 standard in late 1990's. HP has been making wireless printers since 2003.
lpeterson123: What makes wireless so flaky at times?
CameronL-HP: There are lots of reasons. Wireless signals are affected by distance, walls, metal objects, and other wireless devices like cordless phones. However, most of the problems seem to be from how the network or how security software is configured, and these can also cause things to fail only occasionally or in certain situations. Having a good wireless connection between a PC and printer involves several hardware devices and lots of software made by different companies that all have to work together; if something is not quite right in any of these things then the whole solution looks flaky.
Bowman16: I use a Mac, are there any features that would not work if I was to set it up for wireless use
DavidH-HP: All the features will work on a Mac if you install the full HP software solution.
jest1: Thanks for the answer on the router question. The next question, then, is to ask what would be a recommended consumer-grade wireless-enabled printer (or series) just so I can start my research.
JimB-HP: Any of our Photosmart or Officejet wireless printers will work with Wi-Fi certified wireless-routers. Our price points really have more to do with how much printing you do. In general, our more expensive printers cost less per page than our less expensive models.
Bodie08: Why would I choose "spooling" on my PC over "direct connect”?
CraigB--HP: In general, spooling allows you to use your program sooner than printing directly.
ZhuLee3: Jim: What is it like to be an "HP Printing Expert"? What kind of stuff do you get to work on, on a day to day basis?
JimB-HP: I really like my job -- I've always been a radio enthusiast so working on 802.11 technology is really a dream job for me. I'm also fortunate to work with a great team here in Vancouver, WA. More importantly, I like designing equipment that people use in their everyday lives.
TEACHER1: Recently I changed routers, now I am unable to print wirelessly, even though the SES and wireless network light are steady on my Deskjet 6980 printer. What is the solution? Thanks.
DavidH-HP: The wireless light indicates that the radio is on but does not indicate that the printer is connected to the network. First check that the printer is connected to the network by printing a network configuration page from the printer.
AgentRed: I get my internet with a Verizon wireless broadband card. Someone told me that wouldn't work with a wireless printer. Is that true?
CameronL-HP: Our wireless printers use the 802.11 b, g or n standard which is not compatible with the wireless cellular standard. It would be like trying to connect to a wireless network using Bluetooth. They are different wireless technologies.
DavidH-HP: Regarding the Verizon card, it is true that you cannot connect the printer over the Verizon connection, but as long as your laptop has Wife you can print to the printer over WiFi at the same time that the Verizon connection is active. This should not be a problem.
jest1: Is there a "minimum" internet connection that is recommended for wireless printing? We live a bit far from the DSL CO so our connection is sometimes flaky. I would guess that incoming speed shouldn't affect my local wireless LAN but I want to ask it anyway
CameronL-HP: There are 2 parts to your home network. 1 is your wireless router which manages your local network equipment, then your network connection to the world wide web which your DSL provider gives you. The connection speed of your local network is not affected by your internet connection speed.
Bowman16: Are any HP printers 802.11n? I do not want to add an 802.11b,g to my network and cause it to slow down.
JimB-HP: Currently, our printers comply with the 802.11g standard. We are investigation the emerging 802.11n standard.
ZhuLee3: Will there be a transcript of all the questions and answers from this chat available for viewing after the session? I think I missed some questions at the start.
SiobhanF-HP: The chat event begins when you joined. Sorry that you can't see what was said before you joined. I hope to have transcript posted tomorrow or on Wednesday at the latest.
nc256: Where is the future of printers headed? Does HP have any interesting plans with printing technology? And what’s your opinion on whether or not color laser printing will ever approachthe photo realism of ink jet color?
JimB-HP: The future of HP printing will be characterized by wireless connectivity to not only computers but to mobile internet devices. In fact, as mobile devices become smaller (think phone or netbooks), the need to print from your mobile device might become more relevant.
jest1: Am I able to print from my iphone to a wireless printer?
CraigB--HP: You can print photos from your iPhone to HP wireless printers and it works great in my experience. Go to http://www.hp.com/go/iprintphoto to get the details.
TEACHER1: Thank you. I printed a page. It shows that wireless is disconnected.
DavidH-HP: Then you just need to input the wireless settings from your new router into the printer. If your printer does not let you input the settings from the front panel, you can use the CD that came with the printer or downloaded from hp.com to configure the printer again ( look for the option to "add a device" ).
ZhuLee3: Question about security... if I get a wireless printer, what’s to prevent other people within range of my printer, from adding it and printing documents? How is this configured on the actual printer?
JimB-HP: The simplest way to secure your printer is to enable WPA-PSK security for your wireless network and to use a security pass-phrase that is at least 12 characters long. This configuration is very safe from intruders for the foreseeable future.
CameronL-HP: It' is also a good idea to use a unique network name, also called an SSID.
carolj: I have a photosmart C7180 and I have it hooked up to my laptop (windows vista) when the setup completed the printer was put in networking instead of printers and I cannot access it or move it out of there. What do you suggest?
CraigB--HP: You might need to uninstall and reinstall. Before doing this, make sure your get the latest driver from the HP support at: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=1153754&lc=en&cc=us&dlc=en&lang=en&cc=us This is also where you can get a copy of the instruction book.
wizll: Hi, I haven't done much research in wireless printing, but I'm interested as I currently have my printer set up the old fashioned way where it's connected to a networked PC, but if the PC is off I can no longer print, which is obviously inconvenient. Do hp wireless printers have a web gui you can connect to once it's on the home network, or is it simply all done from the printer's interface. I've seen some old wired network printers that only use the printer's ui and that seems like a clunky use.
DavidH-HP: Yes, the HP printers which have networking built-in have what we call an "embedded" web server which allow you to configure settings, check status, and have many other features; on some models you can even scan using the embedded web server.
nc256: Jim: Will color laser printing ever reach ink jet quality for photos?
JimB-HP: While never is a long time, inkjet printers will, for the near future, output higher quality photos.
katiepage: If I'm at home, connected to my office network via VPN, can I access my office networked printers?
CraigB--HP: Yes, when you are connected to the office VPN, you can print to your office printers. However, you will not be able to print to your home networked printers while you are connected to the VPN.
jest1: If a friend comes over to my house with their laptop and needs to print something, are they able to do this just by authenticating with my wireless LAN (assuming I have a wireless printer set up)?
CraigB--HP: In addition to authenticating to your network, you friend will also need to install the printer driver for your printer.
jpszambelan: Is there a wireless USB device of some kind I can connect to my printer if there is no network connection already built in?
JimB-HP: HP sells an accessory that adds Wi-Fi capability to your USB printer (see http://www.shopping.hp.com/product/printer/inkjet/wireless/4/accessories/Q6236A%2523A2L) Also, many higher-end wireless-routers allows USB printers to be connected to them to allow sharing of the printer from the network. Note that this solution often limits you to just printing and not scanning from the network.
rockwoodchev: It seems that my computer can find my printer, but my printer can't find the computer, so that "Scan to computer" won't work. What do I need to do in order to fix that?
DavidH-HP: This can be blocked by security software running on the PC (such as a personal firewall). Make sure that your firewall is configured to allow communication on your local network. You can also unblock specific ports, but the easiest way is often just to allow communication on the local home network. The specific setting varies from firewall to firewall.
SiobhanF-HP: We are nearing the end of our chat session. We only have time for 3 more questions. If we did not get to your question, please post it on the Networking and Wireless board in the Printers and All-in-Ones forum. http://h30434.www3.hp.com/psg/board?board.id=Networking
SSPatrick: Is it possible to print wirelessly to the same HP printer using both a PC and a Mac?
JimB-HP: Yes -- I do this in my home. I have both Macs and PCs on my network without any trouble.
Bowman16: Any plans to do this again?
SiobhanF-HP: Yes we are.
ZhuLee3: Do all of the experts hang out on the HP community? Will we see you posting there after this?
DavidH-HP: Oh yes, whenever time permits. In addition to trying to help people, I learn things too.
JimB-HP: I'm known as Wi-Fi-Guy on the support forums. I hang out there often helping where I can. It helps me be a better designer.
CraigB--HP: I monitor the forums looking for problems to take back to the development lab for investigation. To date, I have only posted one reply.
CameronL-HP: I haven't been involved in the past but expect to be more involved in the future.
SiobhanF-HP: We only have time for one more question. If we did not get to your question, please post it on the Networking and Wireless board in the Printers and All-in-Ones forum. http://h30434.www3.hp.com/psg/board?board.id=Networking
ZhuLee3: Thanks for setting this up!
SiobhanF-HP: The transcript will be posted on http://h30434.www3.hp.com/psg/board?board.id=Networking
TEACHER1: Thank you all for conducting this session !!!!
jest1: Is there an OS limitation to print wirelessly?
JimB-HP: All the OS versions supported by the printer as supported wirelessly. In general, we are compatible with Macs, Windows and Linux.
SiobhanF-HP: We are ending the chat event. Thank you for coming. We hope you found it worthwhile. I will be posting a transcript of the event in the Networking and Wireless board in the Printers and All-in-Ones forum. We will be hosting future Meet the Experts chat sessions on a variety of topics, so please tell us what you thought of the event and how it could be improved. http://h30434.www3.hp.com/psg/board/message?board.id=Feedback&thread.id=525

I work for HP, supporting the HP Experts who volunteer their time and technical knowledge to help others.

I expected this to be released quite earlier. But now that it's in process, I'll wait patiently.
Make it easier for other people to find solutions, by marking my answer with \'Accept as Solution\' if it solves your problem.

I have an Airport Extreme as my wifi hub and an Airport Express to beam music. All of a sudden the Express stopped working and I get the error message "this version of Airport Utility does not support this base station". All my software is up to date and

I have a WiFi system in the house that uses the Airport Extreme for a hub and an older Express for sending music from my Mac to my sound system. Everything worked great till yesterday. When I go to Networks I see the Extreme and I see the Express but the Express is no longer connected and I get an error message "this version of AirPort Utility doesn't support this base station". Any ideas?

This sounds as if you have an older AirPort Express that is no longer supported by the newer Mavericks operating system.
To check and see if that might be the case, locate the model number on the side of the AirPort Express. It will start with an "A" followed by four numbers. Hard to see in the faint print.....so you may need reading glasses or a magnifying class to see the model number clearly.
Model numbers A1084 and A1088 of the AirPort Express are no longer supported by AirPort Utility in Mavericks.
You will need to use a Mac running Leopard, Snow Leopard, or a PC to be able to administer the older AirPort Express.

Home Hub and RJ45? not working correctly

Recently i had a few problems with the Wireless on the Home Hub 3, so i switched and used an RJ45 and boy my speeds shot from 30-40mbs to 77mbs i was all happy, then the upload part of the speed test came along and it spent forever trying to do an upload test then came back error. I refreshed the page and no internet or webpage would load, so i trouble shoot the network and it works again so i try again and the same thing happens any time i try to upload my connection drops from the hub and i have to troubleshoot to fix the problem, i heard somewere that the homehub is funny with an RJ45 =/ i am not wanting to go back to wireless scince the i get faster on a RJ45 is their a way to fix this Issue ?

Hi
All 5 PCs, the vision box & printer here are hard wired using Cat5 cable & RJ45 connectors and in 6 years we have never had a problem.
I make my own cables and they are a bit fiddley, so despite looking fine the pins don't always connect properly and you get all sorts of issues especially if the cable moves.
My recommendation would be that you firstly change the cable, preferably to one that you know works properly.

BPEL 10.1.2 hub-and-spoke or distributed architecture?

Hi,
I'm currently wrestling with the following question:BPEL 10.1.2 hub-and-spoke or distributed architecture?
Hi,
I'm currently wrestling with the following question:
An ESB as per definition of e.g. Forrester should be capable of supporting a distributed bus architecture. From my understanding this distributed bus architecture is achieved by installing some sort of ESB component(s) on all machines that are participating in this infrastructure, together forming a ‘bus’.
As I understand the BPEL 10.1.2 product basically offers two categories of functionality: orchestration and integration. Does this integration part offer ESB alike functionality and more specific allows for a distributed bus architecture? As far as I can see the BPEL 10.1.2 offers limited ESB alike functionality and only supports a hub-and-spoke architecture.
Other threads in this forum talk about using BPEL 10.1.2 together with InterConnect in order to foresee in ESB functionality. What does InterConnect add to the BPEL 10.1.2 integration functionality?
As of SOA suite 10.1.3 these products have been split up into a BPEL product and an ESB product. Is the ESB product in SOA suite 10.1.3 a combination of the integration from BPEL 10.1.2 and InterConnect? Is this new ESB product able to support a distributed architecture?
I’m very much in favor of a distributed architecture compared to hub-and-spoke, as hub-and-spoke requires a very solid and redundant system that is going to handling all message traffic and other functions. When moving towards a SOA giving an ESB a back-bone role, I’m not very keen on introducing a single system that should actually make up this ESB. Distributed would mean all machines are taking care of some basic functions resulting in a fully functional ESB, even when one or more machines are down.
Am I making sense with this? I would like to know how others are looking at these topics.
Regards,
Gershon Janssen

We are struggling with this issue too. The "all-pervasive" vision of the ESB visionaries, in my opinion, means that every node in my enterprise architecture should have access to the bus and I should be able to orchestrate anything that is running on any node in my architecture. We were told to think of an ESB as the equivalent of the hardware bus in computers. From that perspective I thought that:
(1) BPEL and ESB functions would add a marginal increment to the licensing cost of an app server - I should be able to afford an "all-pervasive" architecture.
(2) BPEL and ESB functions would add a "marginal increment" to the memory and resource foot-print. Again, I should be able to afford an "all-pervasive" architecture.
Are these two satisfied by Oracle's products ? Some vendors don't seem to support the above two. In that case there is a disconnect between the marketing and technology departments of the vendors. What am I missing ?
If BPEL engines and ESBs are priced very high, based on economics we will end up with a hub-and-spoke model.
Thanks

EIGRP in a NBMA hub and spoke configuration ?

Hi,
Is there a way to configure EIGRP for a Frame Relay NBMA network using a hub and spoke topology ?
I'm curious that I cannot find any config examples for this, whereas with OSPF in this environment there are plenty of examples.
I'm wondering if EIGRP being a distance-vector protocol this shouldn't be attempted.
PS: I've been at this all day and have only managed to get EIGRP to work in one cofiguration and that was using physical interfaces on all routers and switching off split horizon at the hub router. I used frame-relay map statements with broadcast enabled also.
Any pointers would be appreciated.
Cheers,
Phil.

hi phil,,,
here is the configuration for the HUB router
! hostname ABC
interface Ethernet1
ip address 192.168.2.1 255.255.255.0
interface Serial0
no ip address
encapsulation frame relay
no ip mroute cache
interface Serial0.1 multipoint
ip address 192.168.1.1 255.255.255.0
no ip split horizon eigrp 2001 Split Horizons disabled
bandwidth 112 Bandwidth set to the sum of the remote PVCs
frame relay map ip 192.168.1.5 110 broadcast
frame relay map ip 192.168.1.6 130 broadcast
router eigrp 2001 EIGRP routing process
network 192.168.1.0 Networks running EIGRP
you can have appropriate IP addressing as per your design...
you can have some easy configuration at spoke side with compere to HUB router....

AirPort & USB Hub and Two Printers?

The AP Exp. manual says I can print to multiple printers connected via a USB hub. However, I have a Brother Laser Printer and an HP Inkjet printer. When I connect either directly to the AP Exp. they are instantly recognized and installed and I can print to each one directly.
However, when I connect the hub and attach both printers to it, the only printer recognized is the HP Inkjet. When I switch them on the USB ports (i.e. 1&2), the result is the same. Even if I unplug the HP, the Brother is still not recognized as the only printer connected to the hub.
What could be causing this?

Nope. According to Apple the specifically recommend it: per the following Tech note:
http://support.apple.com/kb/HT1487
"AirPort Express Base Station with 802.11n
Single powered USB printer directly into the USB port, or several printers to the base station via a powered USB hub"
Either way, it wouldn't explain why only the HP printer shows up when connected via the hub.

Airport Extreme, Belkin USB Hub, and external hard drive

I'm having a serious meltdown. I've been at this all day long and I've reviewed SEVERAL, if not all, discussion threads. I've seen my question many times on many threads, but yet to find a solution!
Just got the hub, and I tried today to connect the Belkin USB hub so I could get my external hard drive accessible from my Mac. My external drive worked fine on my PC. I recently moved to Mac.
Printer works with no issue at all, but my external drive does not even list in either the Disk Utility or System Profiler. It just doesn't get recognized. I've tried EVERYTHING...switching ports, connecting directly to my Macbook, restarting, etc., etc., etc. NOTHING.
Anyone have any insight to this? I'm ready to throw in the towel.

Ok I'll try that! Uh oh...now I can't even see the external drive on my PC! I also spent some time looking at the manufacturer's website to see if there's any software I may have downloaded before using the hard drive, but the website is not helpful in that capacity (www.cavalrystorage.com). I don't remember having software when I first started using it. Furthermore, I just looked at paperwork I received when I got the drive back in Nov.06 and it says not to use "the CD if you have Windows", (to install a driver, perhaps?) which of course, I did. But now I can't find what disc I may have gotten with the drive. It also had no specific instructions for a Mac. Although the external drive has wonderful reviews, and says you can use it with a PC or Mac. I hope this helps. I certainly appreciate your help!
I'm starting to think something has gone awry with the external hard drive? I've tried connecting through the hub (my printer works at least!), direct to AirPort, and direct to laptop and nothing.

Airport Extreme "N" and sharing both a disk and a printer

I wanted to run a shared printer and a shared disk on my extremes and while I realize there was only 1 USB port, I wanted to know if I added a "powered" USB hub would it work. I tried it with a powered Belkin hub and was able to maintain both a shared printer and a shared disk on one of my extremes. If others try it, make sure you use a powered hub, and not one that draws it's power thru the USB port. I didn't need to do anything special, so if it does not work for you, it could be a combination of issues with the hub, disks, printers, etc. Next I am going to try one of the LaCie drives that include a USB hub. A powered USB hub runs in the 75 - 125 price range so the 320GB LaCie drive with USB hub at 169 seems like a good value if it will also work to add USB ports to the extreme. If anyone has tried this with the LaCie 320GB drive please post.

ok i am doing the same thing. i have a western digital 500 gig drive and a canon i9900 printer both connected to the airport 'n' using a cheapo powered usb hub from tiger direct. i think it was like 9 bux. that all works fine and has for some time. leopard has added some issues with reconnecting to the drive after the computer goes to sleep but i doubt this is hub related.
one thing to watch is the permissions are changed by the airport on the disk once you mount it there. if you then try to remove the drive and connect it to the computer you will have to modify [or check the ignore permissions box] the permissions.
and if i just unmount the drive from say within finder it will scream when i unplug the drive. i also have to use the airport utility to 'disconnect all users' before i unplug. after doing that the drive disappears from the finder, as opposed to showing it un-mounted.
i have 2 partitions one for my itunes library and one that is a boot-able clone. i have to connect the drive directly by firewire to make the clone [once per week] and until i started using the airport utility to disconnect i was having problems when i re-attched the drive after i cloned.

Compatible Wireless and USB Printer Lists using AirPort Extreme

Long night researching this issue. I bought a new AirPort Extreme (802.11n) yesterday and I LOVE IT. Very fast and no lag whatsoever. Then I tried to setup our printer via the USB port and BAM - issues.
Here is a short summary of what I learned (thanks to all the guys who posted a lot of this info on separate posts)
- Unfortunately not all USB printers are compatible with AirPort base stations. - The AirPort's USB port does not support the "advanced" printer functions, like scanning, copying or faxing, of multi-function printers.
Go to iFelix for a "short" list of compatible and incompatible printers:
http://www.ifelix.co.uk/tech/index.html
Please note, there is a workaround for "some" printers - trial and error is the only way to see if your printer will work:
http://www.ifelix.co.uk/tech/1300.html
I believe most retail printers that use Postscript, PCL3, PCL4, PCL5 and PCL6 interfaces should work.
I learned the hard way that printers that use the "HP LIDIL" interface must be connected to the computer directly and will not work via the AirPort Extreme USB port.
Here is a list from IBM support of HP printers and which interface they use:

GOOD LUCK!!!!

Remember that when you attach a USB printer to the AirPort, the AirPort will perform the function of a Print Server. As you can imagine, if the server cannot locate the printer (for whatever reason), it will treat it as unavailable and not attempt to share it out.
However, like you expect, you wouldn't have to restart a dedicated print server, and thus, you shouldn't have to do the same with the AirPort. Of course, anything is possible.
I would suggest a couple of things to see if they would help: 1) Even though you have a single printer attached, I would suggest in investing in a powered USB hub. Plug the hub into the USB port first, and then, the printer into the hub. You can then power cycle the printer as required. 2) Completely remove the printer and associated printer drivers that were installed and reinstall it.

Printing wirelessly via Airport Express to DSL hub to ethernet printer?

This seems like a fairly standard set up.
My iBook prints just fine when cabled directly to the DSL (Verizon/Westell Versalink 327W) cabled to the ethernet printer, and connects wirelessly just fine through the Airport Express (AX) cabled to the DSL hub, but I can't print wirelessly.
My questions are:
- The hub IP is 192.168.1.1, and the printer is 192.168.1.10. I changed the AX IP (Airport Admin Utility: Network) from 10.0.1.1 addressing to 192.168.1.1 addressing, but that didn't do anything. Does this matter?
- In Airport Admin Utility: Internet, the router address is 10.0.36.1. Does this matter? Should it be 192.168.1.X?
Note: In the Printer Setup Utility, when the iBook is cabled directly to the hub, the printer is automatically identified when I type in the printer IP address under HP Jet Direct Socket, as 'HP Laser Jet 4000 Series' is automatically and correctly selected. This does not happen when connected wirelessly.
Any help would be greatly appreciated.

The problem is that your wireless connection is creating a different subnet. To remedy this, configure the AirPort Express so that the option to distribute IP addresses is DISABLED.
