How to Remote into Wyse T50 thin client

Lot many time if we have to take screenshot of thin client we use camera . Now this can be done via VNC also. Setup VNC server on Wyse thin client using password or without password

Download the VNC viewer from RealVNC.  Once it is launch and connected it gives similar experience as any other remote tools

How to capture TCP dump on Wyse T50

To capture Wyse T50 TCP dump we need to insure that we have "tcpdump" module is installed.  Now open terminal available

1.   

2. Now  run following command to get latest tcpdump

su -
cd /etc/apt
cp sources.list sources.list.back
cp sources.list.orig sources.list
sudo apt-get update

3. Now install tcpdump on Wyse terminal

And run following to autoclean

cp sources.list.back sources.list
sudo apt-get autoclean

4. Run following command to capture tcp dump

5. This will files under /tmp file

6. Now biggest challenge how to copy it? Insert pen drive into thin client and under following path you can copy tcpdump

Integrating foot pedal with XenDesktop

Foot Pedal are used to playback audio or video and used by various different industries. Here we are trying to integrate one such foot pedal with Express Scribe Transcription Software.

These are HID based device which require few policies on XD and then if we need to run via thin client then few setting on VDA

Client USB redirection work with XenApp 6.0 and XenDesktop 5.0 or latter .
1.  Make sure this policies are in place

2. If we need to integrate with thin client then make sure we have registry hack for "AutoRedirect" explained in  CTX123015.  This need to made on virtual machine

To get the PID and VID for this foot pedal use device manager or use any physical machine where this was present
3. When this need to integrate with thin client we need to do force redirect from end device itself. Recently some of the Wyse model do provide option using TCX USB Virtualizer

4. Lastly we should have USB device redirection rules applied on desktop group . Citrix eDocs explain in great detail
Once all these are in place this is how it show up when we use Wyse T50 thin client . Notice when Foot Pedal is plugged into thin client it does get auto detected.

And this is how it show up with Thick client

Citrix Tools for VM does not start what should I do

Yeah sometime you can find that VM tools service does not start and network tab will show IP address unknown

If you check the service it will not start

Check the Application  event log size  clear it and increase it from 64 to 256. This can also be done via GPO

Service will start without any issue :)

I want to backup my Virtualized environment

Every institution wants to backup  virtualized  environment but is it really necessary to do so?  Yes it is necessary but we should know what component is really necessary. Most of the time we plan for hypervisor backup . Hummm how long does it take to build any hypervisor either its VMware or XenServer ?

For VMware I can build it within host in 3 minute using EDA /UDA . All the configuration is stored within virtual center SQL/Oracle database . So if I backup my VC database I can bring up the environment. If my ESX host crash I can build one new in 3 minute . Now why do I need to backup my ESX host ?

If my XenServer host crash I can build new one in 5~10 minutes . XenServer configuration is stored on metadata and this can be backed up on NFS from where it can be transferred to  tape. It would be not more then few 100 MB's . So do we need to backup hypervisor ?

If we have to backup Citrix virtual envoirnment which consist of XenApp and XenDesktop/PVS, just backup SQL server and webinterface server .Should I also be backing up Lic server ? Hell no , you can build new one within 5 minute . So how about virtual machine how should we back these up. Yeah here comes the strategy because backup will consume lots of bandwidth. So should I do snapshot level backup or agent level backup?

Now its era of 10G network and any backup infrastructure if designed properly , I will always prefer agent level backup . It is so simple to backup and restore.

The idea for this debate is to ensure that we do not create overhead for our IT operation team . At the same time we should save some buck on un-necessary backup infrastructure like Storage/Tape management (Iron Mountain) .
