Seeking advice for Wireless LAN solution

I have a site that has a pipeyard in which I am considering covering with Wireless LAN. The transport vehicles that roam the pipeyard have terminals which currently use cellular cards & VPN to connect to an app server that is updated with stock that they move. The server is actually in an office adjacent to the pipeyard. The cellular coverage is poor and the connection drops are frustrating to the operators. For this reason, I am considering covering the area with Wireless LAN and replacing their cellular cards with 802.11a/b/g radios. The pipeyard has no obstructions. The area is outdoors and is about 122 acres in size.
Does anyone have suggestions about what Cisco solution could be applied to this pipeyard so that the mobile operators can maintain continuous connection to their server as they move about the yard?

For starters, you'll need to use mesh access points. You have the following choices:

Seeking advice for backing up Xserve G5 w/ RAID PCI card

Hello all!
I'm a newbie to Macs and server admin, and I have inherited the job of setting up a server at work for file storage. I'll do my best to give a concise description of our set-up - I'm looking for some advice on the last few odds and ends... mainly how we can backup the system.
We bought an Xserve G5 with an option RAID PCI card. We have 3 500GB drives in the Xserve, configured to RAID 5 (giving us effectively 1TB of storage space). We will be using the server for data storage. About 20 computers will access the server over a network; we are using an assortment of Macs and PCS.
I am seeking advice on backup systems for the server. In the event that the RAID5 fails, we don't want to lose our data. We just need a snapshot of the server; we don't need to archive data or to take the HD offsite. Our old server just used Retrospect to run incremental backups every night (with a complete clean backup once a month). Our current thought is to attach large external hard drive to our admin computer (not the server directly) and run nightly backups as before.
The major points I have are:
-Any thoughts on reliable 1 TB external drives?
-Any recommendations on software that can backup from a RAID over a network? I found info for Retrospect Server 6.0 - it seems to do what we want, but is rather pricey.
Thanks in advance for any advice! I really appreciate it!
Xserve G5 Mac OS X (10.4.2)

Greetings-
We all started out as newbies at one time or another-no worries. That is why we are here.
I personally use the Lacie branded drives. They are sturdy and reliable. My only thoughts here are to have at least three external drives-one for today's backup, one for a backup stored securely nearby, and one to be securely stored off-site. Rotate the drives daily so that your worst-case scenario will be a catastrophe that requires you to use a three-day old backup, depending upon how old your off-site backup is. Not ideal but better than the alternative. External drives are cheap enough these days to allow you to do this at a reasonable cost. Plus it is easy enough to throw one in a briefcase and tote it home for safety (just don't lose it!)
I would stay away from Retrospect. If you search these forums you will find several instances of folks having some serious issues with the program. I use a program called Carbon Copy Cloner that does the job nicely for my basement server. There are ways to do the backups via the command line interface as well but I am not so familiar with those commands. You may have to dig a little deeper to find something that works for you.
One of the other advantages of the FW external drive is that you can share it with other users, so perhaps you can set things up to have your network backups to go to that drive. Tis a thought.
Luck-

Password Recovery for Wireless Lan controller

Hi, I am new to Wireless Lan Controller.
I just wanted to reset the password for the Controller. Can anybody help me with this. link/procedure anything will be appreciated.
Thanks & Regards,
Jvalin

I think they mean that they can not type "reset system" since they can't log in in the first place.
The key point to be made is that you need to restart the controller. So power it off if you can't login. Then console in to the controller and type "Recover-Config" as the username. This will default the configuration and allow you to start over with a new username/password.
There is no other password "recovery".

Oracle9iAS WE Support for Wireless LAN Architecture?

Hi All,
Here is one basic question. Does Oracle9iAS Wireless supports Wireless LAN Applications? if so how it could be. can some body provide references to this topic..waiting for the positive response
thanks & regards
krishna

Hi
I have goen through the FAQ which we refereed, but it has little information. stating that yes, there is a support but there is no prrof of concept or some additional information. and one more thing, can i use my cell phone with Wireless LAN to connect ASWE. if so what would be the Application type. which sort of applications would be preferable. it might be looking out of this domain, but if it includes in ASWE then it would be a intresting point to think of.
hoping for the positive reponse and thanks in advance
thanks and regards
krishna

You have set the device to scan for wireless LANs,...

I don't get the "four small hollow squares" icon show up, like it says in the "Essential Indicators" section of the manual, when I'm within range of a Wireless LAN. I do get "Wireless LAN found" in the status bar on the standby screen. How come I don't get the icon?

It does seem silly the way it works doesn't it.
I don't think the one on the active standby screen refreshes itself so you are best leaving that one switched off.

Need advice for wireless iTunes access (have router already)

I'm having a hard time sifting through all the info to find the best solution. I have a MacBook Pro that I'll soon be upgrading to Lion from Snow Leopard, as well as an iPhone, with a second iPhone soon to enter the family. We also plan to get an iPad. We actually have an older iMac that we won't be upgrading, so we're going to move our iTunes library from the iMac over to the MacBook (basically turning the MacBook into our primary computer). We want to be able to play iTunes without having to keep the MacBook plugged into wired speakers. That seems a bit pointless.
We have a wireless router already (a D-Link), so I don't need AirPort Express to act as a router. (We have a 1 bedroom condo, really no reason to extend the network or anything like that.) We have a printer that works wirelessly with the MacBook already. All I'm really trying to figure out is the best way to set it up so that we can have iTunes on the MacBook, playing over speakers (either the ones we currently have our iMac plugged into, or our stereo speakers that we have our TV setup with). Ideally if we could do the same from the iPhone and (future) iPad, that would be great, too.
Does it make any sense for us to get an AirPort Express to do this, or would it just be more straightforward to get wireless speakers that can work over Bluetooth (like the Creative D200 ones in the Apple store)? I feel like the AirPort has the potential to be overkill for our usage, especially since I can't seem to figure out if you can use AirTunes with an iPad, and we don't need it for the wireless printing functions.
Any advice would be appreciated. Thanks in advance!

Thanks Leo! Yeah, I was confused about the 2500 series too because they push the Flex 7500 so much as the "real" solution.
Now that I'm looking in the right spot, it looks like NCS Prime Infrastructure is for the serious folks and we could probably get away without it, right? So that would leave the access points, the controller, and the basic network stuff.

Wireless LAN Solution Engine 2.5

Hi,
we have still this box from Cisco, and we are looking at replacing it.
What is the product we should use to replace it? Seems that Cisco now has several options.
Jorge

Hi Jorge,
since we have no information regarding you wireless environment here a short overview.
For WLAN Management you have two choices:
● WLSE
● WLC / WCS
The WLSE manages the autonomous APs. This means these APs have a IOS running and if the management station fails, they are still working.
Therefore the WLSE is useable in decentral management environments and WAN links!
The WCS manages Lightweight APs. These APs get their software (not IOS) from the WLC firmware and they are upgraded via WLC upgrade. These APs are NOT autonomous. If the WLC fails the APs stop working.
The WLC is the best solution for central managed environments without the problems that WAN links may gice you. Remember: If a WAN link fails the attached APs stop working.
The WLCs can run in a master/slave mode for redundancy, but this will drive your costs up!
If you have many WLCs running in different locations you can manage them with the WCS!
On the other hand in large central deployments the WLC / WCS may reduce the usual mainteneance like AP Softwareupgrade, setup and enable RF Management and some other tasks.
Of course you can deploy IOS to the APs with the WLSE, but you have to copy the IOS Image to the WLSE, create a job and check wether all devices succeseeded. Within the WCS Upgrade the APs get the appropiate sotware autmatic!
In WLSE you have to setup and enable RF Management manually.
To get the long story short: Have some thougts on you deployment:
● Central
● Decentral
How Many APs do you have per location! Better plan two WLCs for redundancy per management domain and location! At the moment one WLC can manage 100 APs. So you should think about the cost for managing 500 APs in a redundant manner!
Actual WLCs can manage up to 12, 25, 50 or 100 APs per Controller, depending on the type of WLC you have ordered. The WLC connot be upgraded from e.g 12 to 100 APs!
One WLSE can manage up to 1900 APs in a WAN deployment (i know data sheets stating 2500, but a costumer of mine gets problems with 1900+ in a live environment).
How many time do you spend in "lower level" work like AP Upgrades, AP configuration, RF Management? In a large campus a WLC might give you some advances in combination with wireless phones, configuring QoS through predefined classes and so on.
The WLSE gives you the more granulary acces to the wireless network!
I guess this should be enough for the moment.
As ScottMac writes in his posts:
Good Luck.

Seeking advice for a scenario

Hi everyone I am currently a student pursuring my CCNA and one of the things we need to do is a case study. What I've got is a building that is going to use 3 subnets out of a given address space of 192.168.100.0/24. Looking for advice on what router (or routers if more than 1 would be better) would work best for this situation.

Beside the information provided in the other posts, for basic routing, L3 switches and routers often do much the same. However, the former tend to be able to provide much higher level of performance, the latter additional features. Sometimes, especially with the non-chassis platforms, you might need to use both device kinds to obtain both (LAN) performance and (WAN) features.
For example, your 3825 (350 Kpps) could struggle to route 100 Mbps of traffic, where even the smallest (8 port) 3560 (2.7 Mpps) handles much more. Yet, the 3825 supports various interface types, NAT, firewall features, advanced QoS, VPN, etc., while the 3560 doesn't.

Seeking advice for a nagging BT related issue

Dear Forum,
I would appreciate your advice on a performance issue related to using the BT SW stack.
*Some information*:
Non-Toshiba notebook, Intel dual core @ 1.2 GHz, 2 GB RAM, running WinXP pro (5.1.2600 SP2 Build 2600), all MS updates, company computer, MS Office 2003. I got the PC two months ago and separately purchased the 'Wireless 360' internal Bluetooth USB module (Toshiba device, VID 413C, PID 8140, firmware 43.15). I installed the hardware module and BT software stack (Toshiba BT Stack, version v4.41.02(D)). I'm using BT mainly to connect to my mobile phone, for which 'Nokia Suite' v6.85.141 is installed. The Nokia Suite works fine and as expected using the BT link.
*Problem*:
When opening a .doc/.xls file by double clicking it in Windows Explorer, the system response is very slow. Like 40 (!) secs to open a 30 KB Word document. This is reproducible. For some other files, like .pdf the response is much better. Starting Word via the start button and using Word's file/open to access the same file is OK. Opening Windows Explorer using Windows-E hotkey is very slow as well, opening Windows Explorer via start menu is normal.
I do not see any 'heavy' disk access or 100% CPU during the delay.
For the rest, the notebook seems to run OK.
*Findings so far*:
1) Re-installing the Toshiba BT Stack did not improve things
2) When shutting down the PC, frequently the TosOBEX.exe process needs to be ended ‘manually’
3) Uninstalling the BT SW stack makes the PC respond normal again
4) Disabling the BT Manager (system tray, right click BT icon, exit) has same effect
5) Stopping the TosBTmng.exe process removed the problematic effect as well
6) Starting the PC with all non Microsoft processes disabled – except the BT stack – give a normal responsiveness (!)
7) Uninstalling McAfee virus scanning tools does not help
8) Replacing the BT stack with version 5.10.12(T) solves the issue, but creates another problem: process “services.exe” continues to consume too much CPU time (~35…40%)
9) I have not been able (yet) to identity the non BT process(es) which effect(s) this problem
*Questions:*
Anybody familiar with this effect?
Any suggestions for next steps?
Forum’s advice would be appreciated!
Wytze

Hi people. Same thing here.
My Satellite A100 delays opening word and excel 2003 documents only when bluetooth manager is running.
I don't see a cpu load on the services process though (or any other process for that matter).
I had version 4 installed when detected the problem. Switched to 5.10.12(T) and the wait time is still there.
Then I followed the previous post suggestion of wiping-out everything bt related and install again. But still no luck.
Even reinstalled office but that didn't help either.
Some maybe useful information: I'm running Nokia PC Suite 6.85 over bluetooth and Adobe Acrobat Professional 8 which integrates menus in Word and Excel.
Wait time still occurs when killing all PC Suite processes or changing acrobat installation to not integrate in word.
This kind of time wait resembles some king of name resolution timeout. But why only office apps?
Has anyone already have any light to shed on this?
Regards

Parsing XML with Java - seeking advice for method to pursue

Hi guys
So here's the deal: I want to parse some XML from a server, get all the data I need from it, then shunt that data to the classes that need it. However, I'm really not sure what the best way of parsing the XML is.
I've just written a class for obtaining the file, and one for building a DOM from the XML file. But looking at org.w3c.dom in the Java API documentation (see HERE) I'll have to implement shedloads of interfaces to be able to take advantage of the DOM, and I don't even know a lot about it.
So am I best just writing a simple parser based on regular expressions to get the data I want? There's about 5 attributes in the XML file that I need to get - 5 for each instance of the containing element. So I don't think it'll be hard to do with regular expressions.. plus even if I did decide to implement all the DOM interfaces, the only way I'd know how to do half the stuff is with regular expressions anyway. I mean, how else would you do it? How else could you match up Nodes according to the Strings you're using for the elements, attributes etc?
I worry that a parser using regular expressions might be too slow... I'm building this as an applet to visually display information from the server. I have nothing to support those fears, I'm just not experienced enough to know whether speed would be a problem if I chose this route... I don't think it would, but really need confirmation of that suspicion being unfounded.
Any advice would be very, very welcome, as I'm tearing my hair out at the moment, unsure what to do.

Komodo wrote:But JDOM is not in the core class libraries, is it? So if I want to create an applet embedded into a website, am I able to get people to download that as well?
Sorry, I don't know anything about applets.
Komodo wrote:Everyone's advice is appreciated, but my core question remains unanswered - would using regular expressions, considering how simple and unchanging the XML files are, be a viable option in terms of speed?
Yes! I've done more than my fair share of XML processing with REs. It's not always easy. I often wish I could just use something XPath-like. But it's certainly easy to do and would probably mean that you'd have something up and running quicker than if you spent time investigating pure XML parsing approaches.

VLANs for Wireless LAN controller

Hello,
Just finished the configuration of wireless controller and connected Access point.
I have a scheme like this:
Cisco 3945 with WLC on SRE------TRUNK-------L3 switch-------TRUNK----------L2 switch--------ACCESS PORT-------ACCESS POINT-----WIRELESS----CLIENT
2 VLANs on the WLC (with DHCP on the router):
1. management (VLAN 200 for management and access points - works fine)
2. clients (VLAN 300, all setting are same, except Enable Dynamic AP Management setting, which is off and IP subnet, DHCP on router too).
Clients are able to connect, but they can't get address or ping the gateway of the clients VLAN (if i put this VLAN in the WLAN
Interface/Interface Group(G) setting), but everything is fine, if i set management VLAN to Interface/Interface Group(G) setting of the WLAN.
do i need to add any additional setting on the switches or on the router to allow this clients VLAN?...
P.S. i am able to ping both vlans, or get DHCP address from the switch and router...

yes, just for test, i set up IP from clients VLAN on the L2 switch, and from that switch i am able to ping the controller interface (clients interface).
Just to be clear, do I need to have both VLANS (ap-management and clients VLANs) on all the switches and router on my setup?
As I understand i need to have ap-management vlan only on L2 and L3 switches. Any other VLANs go throught the tunnel between AP and WLC?

Seeking advice for a self-teaching programme of new Java techs

Hello,
after a few years of technically poor projects (I learnt a lot in terms of process, quality, and non-Java technologies, by the way), I'd like to catch up with mainstream Java development.
I am preparing a programme to learn a few technologies I have missed over the past years. I plan to develop a couple of utilities (simple CRUD apps) on my spare time, gradually including bits and bits of the bricks I want to grasp.
I need some advice though to make this learning effective.
My first priority is to invest in reusable knowledge, so I will stick to "standard" bricks, and will aim mostly at off-the-shelf tools that work out of the box
(for example, I don't want to spend hours to fix a DB install&configuration issue, as I know I will probably never be paid for that kind of job).
Specifically, the technologies I plan to embrace are:
* Java SE 5 and 6
* jUnit 4
* Spring
* EJB 3 & JPA
* Web UIs
Here are the points where you might help me:
* JDK 1.5 vs 1.6
No real doubt here, the biggest language gap was introduced by 1.5. If I'm correct, 1.6 essentially brings new APIs; as long as those APIs are not my primary target (I'll try them only after I've completed my first round of catch-up :o), I am not missing much language-wise, am I correct?
I could also jump directly to 1.6, ignoring its new APIs, and concentrate on
1.5 language features, but the risk is stability (losing time with a 1.6 beta bug).
* jUnit 4
Nothing special, except I have practically read nothing about it on these forums (contrast this with TSS, where there are regular threads disputing the relative merits of jUnit vs TestNG).
Is v4.0 a non-event? It seems to bring some niceties (mark test components using annotations), but how much comfort did it bring to those of you who have used it over jUnit 3.8.1?
* Spring
Leaving aside that it's on my must-do list, I actually wonder which version I should try?
I also feel I should try it first on a non-EJB app, to avoid mixing concerns. I will skip the JDBC wrapping API though, as I already have a lot to do with other persistance APIs.
Any feedback?
* EJB3/JPA
(I formerly worked with generation 2.1 of the EE specs)
1) The biggest issue here is to find a reliable EJB3 container.
* I've heard JBoss is EJB3-ready, but I don't think it's certified yet.
* Project GlassFish (Sun-driven open-source JEE5 container) is still in the making
* Sun SASP9 is, well, released, but I don't know how much of JEE it supports, and haven't investigated into the licensing details yet
Any feedback on what you're using as a JEE5 container?
2) As far as EJB vs JPA goes, I also have the plan to use the persistence API
outside of EJB (likely, I will develop the same simple CRUD app twice,
once as a Webapp and once as as Swing app, both over the same DB schema).
But maybe this is pointless, as the entity annotations and API are agnostic; have you experienced some difference that deserve thorough learning?
3) Obviously I will need a DB. If the EJB container includes one, fine, at least for the EJB part, otherwise I'll need to install and configure one, that will need to run on a desktop PC on MS WIndows, and preferrably include a handy SQL client console for manual verification.
I know enough of SQL to build even a sub-optimal application schema. However I know nothing of a DB administration, and I don't want to invest in that direction.
Any advice as to a simple off-the-shelf free DB that runs on Windows?
* Web UIs
The dilmena here is two-fold:
1) In term of "view" technology, I hesitate between plain JSP and JSF
If I understand correctly, JSF is a specification for reusable view components.
My local job market leaves me no oportunity to be a UI component developer, whereas I am more likely to someday be tasked to integrate 3rd-party UI components into a business project.
Is my surface understanding of JSF correct? In this case, how much of JSF should I know if I don't have to develop JSF components?
2) In terms of controller, as part of my Spring learning, I'll probably have a look into Spring MVC.
My question is, how much of the servlet/JSP API does springMVC show/hide?
Is it a good idea to use springMVC to learn servlets and JSPs, or should I stick to manual servlet+JSP?
I should add that I've worked with servlets/JSPs formerly (as of J2EE 2 or 3),
I only need to dig new servlet/JSP features.

Seeking advice for a wookiee video person...

I'm shooting alot of videos lately. Typically - they just sit in a folder when I transfer via usb to my dell laptop (sorry I don't have a Macbook pro quite yet!).
I know there is Windows Movie Maker and some other "free" junk out there.
I see Camtasia looks pretty fabulous - but I think all I need is something simple to basicaly do minor editing and then compressing and prepping to share via the internet in various ways with family and friends.
Would QuickTime Pro give me all I need or should l look at buying both QuickTime Pro AND Compressor 4?
(Assuming these are both available for Windows 7).
Any advice would be appreciated.
Thanks,

Compressor is Mac only
QT Pro will only act as a cut editor so hardly the application for you, there is no transitions, titles sound mixing or effects.
Adobe Premier Elementsis fantastic value for money for Windows machines if you plan to do decent hobbyist editing. Look at the website here:
