Help needed setting up cluster communication network

Hi,
I need some help setting up a two node cluster communication network.
I have two virtual Servers each with four virtual nics.
I want to create a network for:
Management
Heartbeat
Live Migration
iSCSI
What type of switch would I need to create for each of them? (External/Internal/Private)
I presume that they would all have to be external as they will have to be able to communicate with the other host in the cluster through the physical network.
Would I need to configure VLANs on the physical switch to keep the traffic isolated?
Thanks

That's all. I don't see any reason to create 4th node. Regarding the iSCSI target - for the test you can install this one
https://www.starwindsoftware.com/starwind-virtual-san-free on the Hyper-V host which can create iSCSI disks. Just create Internal network for the iSCSI traffic (add third adapter to the
FS nodes of course) which is providing network visibility between the VMs and the hypervisor. (you can use the external network too of course).
Regarding the live migration - this is something you cannot test with single hyper-v host. You'll need at least two. You can try ESX which can expose virtualization instructions to the VMs and create two Hyper-V VM to test live migration.
1) It's actually possible to install StarWind Virtual SAN on the same hosts where hypervisor (in this case Hyper-V) runs. That would build so-called hyper-converged setup, something Microsoft is going to represent with Windows Server 2016 (vNext) and Storage
Spaces Direct. Except MSFT requires at least 4 nodes and StarWind can do 2 and 3 :)
2) All hypervisors except Hyper-V do support "nested" virtualization these days. So for very lean labs f.e. ESXi sounds like a better choice.

Help needed setting up print server

i got 2 printer:
1 usb inkjet epson 1290
1 hp5100 network
i have 1 server:
serving epson for our col proof using powerripx as driver and shared via os x print server
i have 2 network interface card on the server.
my problem is: the position of the server in the office has only one network interface port, i want to have my HP connected to the 2nd network interface of the server and the server connected to the only available network point there and thus have the server serving both printer.
have set up the en1 interface, enable NAT, dhcp, firewall, but the server itself does not recognised the hp which is connected to the 2nd ethernet interface. when i move it on top of the ethernet list in system preferences it does recegnised it but the the whole print server is not accessible on the network.
can someone with more experience help me set this up.
thx

I didn't say it's impossible. I just offered an easy solution to your problem that will save you and you users some hassle in the long run (eg. when you come to troubleshoot you wn;t have to look at 2 networks and a firewall). I guess I just like easy solutions. And ,dude, 20 bucks...
If you want to go the hard(er) way you need to:
1. set up a second network address range on the second card
2. give the printer a fixed IP address within that range
3. ensure firewall is not blocking packets from/to the printer
4. config the printer on your print server & clients

Getting help for setting up a "good" network

Hi all,
I've been "managing" our network and doing the IT stuff even though I'm not a "true" IT guy, just a graphic artist dabbling in the stuff. I want to get some help on moving our multiple public IP address network to a more secure single Public IP address. I don't know where I can get that help so I'm taking my chances here even though this is not specific to Apple server.
Here's the equipment we have:
Apple Extreme dual band
Apple Server 10.6.3 for file services, iCal, iChat, DNS, Open directory, Address book, Web.
FTP server using CrushFTP on a Mac Pro running 10.6.3
Two ADSL modem from same ISP, one 16 Mbps the other 10 Mbps
a Peplink Balance 310 for load balancing the traffic (and it's not working as advertised as far as I could configure it.
30 static IP addresses hooked to the 16Mbps modem/router
a gigabit switch ASANTE Intracore IC36240
a 100 mbs switch ASANTE intracore 3524
I'd also like to be able to log into any machine remotely with ARD. Right now, it's a peace of cake with everyone having it's own public IP address, but how will I make this work with DHCP? I'd also like to be able to have VPN enabled.
I have no idea how to make the best of this equipment so if you have any insight or know where I can get some help to set that up, that'd be great!

There are as many 'good' networks as there are network requirements and hardware combinations.
Get a server-grade firewall, if that peplink router can't provide that function.
Figure out what's up with the peplink router.
If the peplink isn't working and if it doesn't have firewall capabilities (I've not read the specs), I'd replace it with a firewall with dual uplinks.
Once you get DHCP going, you'll have two IP subnets, and you'll have to set up subnet routing for your gear. Other than that (and with that external server-grade firewall), the remote connections are straightforward.
The server-grade firewall should have VPN end-point servers for pptp and l2tp, and probably ssl, and probably a DMZ. RADIUS support, likely. For this case, dual uplinks and support for running both.
Stay out of 192.168.0.0/16 for your private stuff.
I'd likely set up the public static IP for the router, the DMZ, and key stuff that needs to be public facing. I might well run the rest of the stuff in a private IP block.
None of which involves Mac OS X.

Help Needed Setting Up IMAP Relay?

I an currently maintaining an OS X 10.4.11 Tiger server, running on a PowerMac G4 Mirror.
Currently, we have our mail setup through our isp via pop (they do not offer imap). All of our employees have set up several access points to the pop server (i.e. home, office, smart phone, etc.). However, the problem arises that as each device is maintaining its own mail, when accessing mail on each device, mail read on one device still shows as unread on the others. As well as, any mail sent from one device, does not exist on the others.
To eliminate the duplication, and missing mail, I thought setting up an imap server would keep all devices in sync.
My thought is, collect all the mail from the isp pop server, onto the OS X server and then have the employees access only the imap server from all the devices.
i.e.
Setup imap server
setup imap server to download mail from pop server, and save in the appropriate account.
setup all client mail accounts to access imap server.
I have been able to set up the imap server without any issues, however, I have not been able to figure out how to get the pop server mail from the isp into the local imap database.
I hope this make sense.
I know there are free services out there that will do what we want, but we do not want to rely on an external service if it is a process we can maintain internal.
If anyone can help me set this up, or suggestions on how to approach this problem, I would be very grateful.
TIA

I'd probably have a conversation with the mail ISP along the lines of "add IMAP, please" and that will either be followed by happiness, or by migrating to another mail vendor, or migrating to local mail services.
I've bucketed mail over (via imap), and it's not really a good solution; there are a number of wheels that need be kept spinning and by the time the dust settles (outages, glitches, the usual cruft), you might as well either re-host mail to to another mail ISP that offers imap (gmail, for instance), or simply run your own mail server.
Usual tools are imapsync and offlineimap, and those target (obviously) imap and not pop. (I haven't seen much that does a pop pull, but it's likely feasible.)
If you decide to host your own, you'll probably want to upgrade to something newer than the PPC gear, and you'll need to sort out your public forward and reverse DNS for your mail server, and ensure all that matches your MX record.

Help needed setting up access point to public network

Hi from a newbie,
Assuming they are suitable, I want to use one (or two) AP1232AG-E-K9 access points for Internet connection through a public wireless network (BTFON), where wire broadband is not an option. I've downloaded what I think is the correct manual for the APs and I'm now scratching my head as to where and how to start setting them up. I want to use these Cisco APs in the hope they will give me better wireless performance than I'm currently getting, which is frequently flakey.
I've tried to reset the APs to the factory default but there seem to be different ways of doing this depending on what you want and what you've got. I made up a console cable to access the console but there even appear to be different versions of this so I'm not sure if the cable I have is the correct one.
I have setup and used lower end wireless devices in the past but these Cisco units seem real complicated and I'm going to need help in getting them working.
Any assistance would be much appreciated.
Kind regards,
Glenn.

Some help needed setting up NAT in 2x Airport network

I'm wondering if anyone can give me some advice on how to get port forwarding to work on my network.
DSL comes into the house downstairs and from the DSL modem it goes right into an Airport Express. I am on the second floor though, and the Airport's signal isn't strong enough for my G5's antenna to pick up. That's why I have another Airport Express on the first floor, expanding the Airport network.
The two Airport Express units are in a "WDS".
I would like to run a home server, so I have to open up port 21 and forward it to my G5, which gets its internet from the 2nd Airport Express unit.
How do I do this? The Airport's have IP's in the 10.0.0.x range. The G5 is in the 192.168.2.x range because it also connects to a wired router. Do they both have to be in the same range?
Port Forwarding seems disabled on the Airports because I use WDS. I can check the Distribute IP checkbox in the Network tab, but then I get a warning it shouldn't be enabled with WDS on.
Any ideas?
Thanks in advance,
Maarten

Hi Henry,
I managed to get it working. I thought port fowarding was greyed out on both Airport units, but it only was on the relay one. Not on the main one. Also, I first accidently forwarded port 21 to the G5's wired IP address instead of its wireless (Airport) IP address.
The setup is exactly as you described (your 2nd paragraph). The wired router is only there to connect 4 PC's to the G5. They don't need internet (I don't want Windows to have internet), they just need just data transfer with the G5 (MIDI data and VNC control). It's on a different IP range than the Airport network.
One issue I am still experiencing is that when Airport is turned on on the G5, the router network (the 4 PC's) don't appear in Finder > Network. When I turn off Airport, the router network appears within a second. So there is a file sharing conflict or something there.
Thanks for your help,
Maarten

Help needed setting up network

Hi
I have an NTL/Virgin Media cable modem with 20mb service.
I did have this connected to a WRT300N 4 port wireless router which had 1 PC running XP connected to port 1.
port 2 had a mains powerline ethernet adaptor which fed to an xbox360.
port 3 went to a DLink 16 port which had 1 Vista PC and an HP Laser printer attached.
I also have from this hub 1 airport extreme and 1 macmini which has a 1TB usb hdd as iTunes library which was wirelessly serving an Apple TV.
my Macbook Pro laptop was getting wifi from the airport extreme but backing up to a 1TB time machine via ethernet.
allthough all was working internet speeds seemed very slow (even though not all on at the same time) on speed tests i was getting around 2mb downloads. so i thought i would try and refine the setup.
by plugging the macbook pro into the cable modem i get speeds around 17-19mb, as soon as i put the wrt300n in between speeds drop back to 2mb even just putting the dlink hub in between the modem and macbook pro the speed drops right down.
can anyone help with network setup suggestions where i can let my wife use xp for internet and email whilst i can use the macmini to download itunes tv, movies and music and stream to apple tv and occasonally xbox online without lag etc???
all help greatly appreciated

Agreed. I'd keep at it yourself. I guarantee it will be something simple.
what are the benefits of a switcher? (never used one before) any recomends?
A switch is just like a hub, except that instead of always sending packets to your entire network, it only sends them where they need to go. The benefits grow with the size and speed of your network. Switches used to be much more expensive than hubs but not any more. Normally I'd recommend almost any Linksys device, but in this case dlink seems to have a better one:

Again, I don't think your dlink hub is responsible for this dramatic bottleneck though.

Help need setting up remote desktop (on a router)

hey networking pros,
I have major trouble setting up remote login (remote desktop).
Specification : OSX tiger, LINKSYS
now i have managed to use tightVNC and manage remote desktop BUT that was when i was on the same network. Now my laptop lies at home and at school (work) i have windows running and want to access my mac at home. I cant manage to do that. Since i am on a different network and that i have router at home and also i do not use air port express (i use a linksys)
I need a static ip which in need to know the DNS servers (adelphia dosent give that to me since i am not a business customer). I have enabled port forwarding (5900) i have even set up an an account with dysDNS.org (i dunno how that helped).
can some one please give me with step by step instruction.
thanks

You already have most of what you need, but you do need a little more understanding of what you're doing.
Keep in mind that the Microsoft Remote Desktop Connection client is one-way only. You can connect from a Mac to a Window XP Professional computer, but not from Windows XP Pro to Mac OS X. What I describe below is how to connect from a Mac on the Internet to a Windows XP Pro computer at home.
First, Remote Desktop may look like VNC, but it's not the same thing. Therefore, port 5900, which works with VNC, won't work for Remote Desktop. You'll want to port forward 3389 to make this work. When you go to your router and make this port forward entry, you'll enter the IP address of the machine you want to direct all RDC traffic to. This gets the RDC traffic from your router to your computer.
You went to DynDNS.org to help you find your router on the Internet. The IP address, as you've researched, can change. But if you set up your router to report its IP address to DynDNS then you can always connect to your router by name. You don't have to keep track of your IP address changing. DynDNS will do this for you. This gets the RDC traffic from you to your router.
So, the steps are:
1. Set up a DynDNS.org account and you'll give yourself a name such as "myrouter" so that you can use a name like "myrouter.homeip.net" to connect to your home network.
2. On your router, port forward all incoming Internet 3389 traffic to the IP address and port 3389 of your computer.
3. On your Windows XP Pro computer (you can't do this with Windows XP Home) enable the Remote Desktop Connection software (right-click My Computer --> Properties --> Remote tab --> select the second checkbox).
4. From a Mac somewhere on the Internet, open the RDC client and enter the DynDNS name you gave yourself and click the Connect button.
5. Your Mac will contact DynDNS and get your current IP address.
6. Your Mac will then connect to your home router, which will forward all RDC traffic (coming in on port 3389) to your Windows computer in your home.
Hope this helps! bill

Help needed setting up WebUI for Wireless Gateway

I have a problem setting up a webUI for my demo project.
I am just doing a simple WSN application measuring temperature on a WSN-3121 thermocouple node, and logging it on a wireless RT gateway NI 9792.
Then I wanted to create a web UI for it, and display whats in the gateway's UI - see project.
SO I'm coming up stuck with the web UI. I've tried reading as much as I can but I still dont know what I'm doing wrong.
As far as I can see, I need to create a web service in the build specs for my gateway, and place the gateway_main.vi as the vi to use. Then build it, and deploy it. Once that has happened and I run the vi on the gateway, I created a webUI as shown in the pic, where it imports the web service from the gateway using 192.168.0.16:8080 - that works fine.
When I run the webUI, it just sits there and times out.
I am using LAbview 2010. Please help.
Solved!

Hello markza,
Your approach to using Web UI Builder and understanding its use case is exactly right, the issue lies in the web service you have deployed. The VI you are building as a web service, i.e. gateway_main.vi, has while loops in it and hence cannot be used as a web service. The reason for the timeout is that your UI Builder app is calling the LV2010 web service and is getting stuck there waiting for the while loops to complete. Also, the cluster datatype is not supported in Web UI Builder so you would have to break up the Wireless Node Sampling Time input into two separate numeric inputs.
I would recommend creating a subVI out of your code inside the inner while loop in gateway_main.vi. This subVI should have two numeric inputs to replace the cluster (as mentioned above) and not have either of the Start or Stop boolean inputs. Outputs would stay the same i.e. two doubles and a boolean.
Let me know if that helps you and if you have any further questions.
Thanks!

Help Needed : Setting JDBC Datasource in Crystal XI using Sybase 12.5??

All,
We are migrating our systems to the Crystal XI from Crystal 9 Reporting Servers. I need some technical assistance on the Java API ( use of the Datasources) .
Problem: Currently in Crystal 9 we are using OLEDB datasources to connect to various Sybase 12.5 databases (which is been set programmatically at runtime). After I changed the Java code for getting the report object from the Crystal XI server instead of 9. I stared facing the dbLogon failed exceptions.. But surprisingly it does work randomly on only one datasource for a given session (AppServer Restart).
Need Help on Topics:
1. Is there any different way of configuring/usage the OLEDB datasources for CrXI? or any Java API changes while setting the datasource when using OLEDB?
2. Configuration required for using Simple JDBC connection (Sybase) instead of OLEDB? Can I get detailed help on this.
I will prefer using JDBC for CrXI using the Sybase 12.5, but there are very less documentation for how to configure and set databases at runtime.
Many Thanks in Adv.
Regards - Sudhir Deshmukh | Solutions Lead

Hi Sudhir,
For Building up a connection for OLEDB we need :
In order for Crystal Reports to connect to a database through OLE DB, there are some requirements that must be met:
u2022     The database client software must be installed on the client machine.
u2022     The client machine must be able to connect to the server from its client software
u2022     The client softwareu2019s working directory (example. c:\orant\bin) must be in the Windows search path
u2022     The OLE DB provider must be installed on the local machine.
We have the connection for crystal reports through OLEDB :
The process by which Crystal Reports access data from an OLE DB data source consists of these five layers:
Crystal Reports Layer
OLE DB Translation Layer
OLE DB Layer
DBMS Translation (OLE DB provider) Layer
Database Layer
The data translation is similar to the ODBC connection model. Crystal Reports uses CRDB_ADO.DLL to communicate to the OLE DB provider, which communicates to the database. Crystal Reports can connect to any database as long as that database has an OLE DB provider.
When creating a new report in Crystal Reports, OLE DB data sources are found in the Create New Connection folder with the OLE DB (ADO) connection.
Regards,
Naveen.

In order to get this to function, there are some baseline server configuration requirements that you need in order for it to work.
1) Define the authentication Domain on the webserver
2) Define the authentication Domain on the web profile
3) Enable Single Sign-On
The following document in 'My Oracle Support' will provide you with the details on configuration related content services.

Help needed setting-up a Y-Cam on a WRT54GS

Has anybody set up a Y-Cam Knight surveillance camera using a WRT54GS router. I have set one up on my network. All my PC’s see it ok, the problem is I should be able it remotely access it from anywhere in the World with no PC’s on as it has a built in server, but I can’t nor can anybody else that I give my ip address (not the network address) to. I (and others) can access it using my ip address when I have the PC on and I run a third party program WebCamXP 5. It sends out a “movement detected” warning e-mail to me ok with no PC on, I have done all the setup as directed, static address, port forwarding ect .Has anybody got any ideas on the settings so I can remotely access it.

In order to Access camera remotely you need to forward ports for your camera on the router . And also make sure that the wanip address on router should be public.

Help needed setting up 5th Gen Time Capsule as a wireless hard drive with Windows

I've got hold of a Time Capsule as I managed to snag it for a decent price and, to be honest, it looks better than other options out there, but I'm having some issues setting it up how I want it. My wireless router is downstairs and I connect to it from my desk on the first floor, which is where the Time Capsule will be as well. I basically just want to use it as a wireless hard drive to store movies and the odd document. I really need some guidance on how to go about setting it up, as Apple don't seem to provide any user guides for Windows at all and the Airport Utility is essentially a very broken piece of software - all I've managed to do so far is run into a series of blinking light warnings and errors.

You cannot setup the new Gen5 TC from windows. It is clearly stated in the specs that it requires v6 utility which has not as yet.. and perhaps never will be made available in windows. In other words this is now an Apple device and almost exclusively for apple. Or at least a mixed network. Without Apple clients you will have continual issues.
If you have iphone or ipad or even an ipod with iOS v6 or later.. you can download the iOS version airport utility for setting up the TC. Once setup windows can use it.. with some issues.
I don't know if you can return it.. but if possible I would. You can buy a wireless synology or WD or lots of other brands now. what they might lack in looks they make up for in functionality.. sadly in the end.. functionality is essential whereas good looks are merely that.. good.

What led you to believe that is the order in which arguments will be processed? There is no defined order, and it's certainly not alphabetic. Print is expecting an object with named properties that it can reference - not simply an ordered array.

Help needed setting up an accelerometer via serial port

Hoping you might be able to give me some advice and point me in the right direction as my experience with labview is limited.
I am wanting to read data from an accelerometer streaming through a serial port. Using the labview examples i have no problems in connecting to the device and seeing the data but i am going around in circles trying to work out where to from now.
I need to create a VI which would show data streaming and then gives the user the ability to save data for various time periods to a text file. I am getting stuck as the data from the accelerometer is constantly streaming in 20byte packets every 2ms in the following format: 7E 00 0E 83 00 00 26 00 01 0E 00 02 00 01 F9 02 64 E5, where 00 02 01 F9 02 64 is the data of interest and of course when starting to read from the device it isnt necessary going to begin at the start of the packet.
I am assuming that inside the while loop i need to get the vi to scan the string to find the start of the first packet and then begin writing it to an array using a shift register for each sample with the left over from the string if not reading the full packet being attached to the next read, then if the data is to be saved to a txt file get it to enter a for loop for the user to define the number of samples to be saved or use an index array option to save a subset of data to a txt file.
Would greatly appreciate any device or examples of the most efficient way to set this up before i lose my sanity!

The easy way is a three step process.
First, acquire 2n-1 bytes (39 in your case) so you are sure you have a full set of data. Parse out the first full set using the string utilities (match pattern, split string, etc.). The remainder of the string is the start of your next data set.
Second, acquire enough points to get the next data set and parse it.
Third, continue looping and getting 20 bytes (keep verifying your start and end so you know if there are glitches).
A harder, but far more robust, way, is the following:
Read in data until you get your start sequence. A circular buffer would be useful for this (you will need to implement this yourself).
Read in your data of interest and record/save/...
Read in the terminator.
Repeat as needed.
For all of these, you can use a flat sequence in a loop, but a state machine is far easier and more flexible in the long run. Check out the LabVIEW help and these forums for how to create and use a state machine.
It is often easier to use arrays of U8s instead of strings for this type of data manipulation. Under the hood, they are the same thing, so the conversions between the two are highly efficient.
