We are planning to deploy some clinical autologon iGEL devices, the idea is to have these IGEL devices to autologon to a XenDesktop desktop pool (this is working so far). The IGEL TC need to be autologed on a W10 VD and they shouldn’t be at the iGel desktop, if they are NOT we are looking for a way to send email alert to a distribution list for them to check providing the name of the thin client (hostname).
From one of you scripts I could use this, however is there a way to check if there is an ICA session running for XenDesktop / sessions rather than VMWare? Also could you help to modify the code to send an email if there are not ICA sessions – we will be using an external SMTP relay server – smtprelay.domain.com smtprelay.domain.com using sender igelalert@domain.com to receipient DL-IgelGroup@domain.com.
Would it be possible to re-run the script every 15 minutes?
Thank you so much! 🙂

It looks like that script already checks for XenDesktop sessions; it’s in the ‘pgrep wfica’ part. I’m not sure about the email part… sendmail is a common S.M.T.P. program that is often built-in, but from my quick check, I didn’t see any S.M.T.P. programs on an Igel thin client. It might be possible to add it as a custom partition, but there might be a better option. For running it periodically, you could use cron or a systemd timer, or just use a ‘while $true’ loop with a ~15-minute pause inside the script.
Thanks Jeremy. I don’t know much about scripting with this language just basics. So the following line if ! pgrep -x “vmware-remotemk” > /dev/null && ! pgrep -x “wfica” > /dev/null checks for both VMWare or XenDesktop? I only need to check XD sessions, how can I check only for XD sessions? Can you schedule the script to run every 15 min on all the thin clients via UMS policy?
if ! pgrep wfica; then echo Hello; fi
That will print Hello if wfica isn’t running (wfica is the Citrix Receiver/Workspace Application process)
I have a script running under the user account that is configured to ‘autostart’ as a custom application.
If you want to run it as root, then you can make it a systemd service or timer. Here is a short example that doesn’t actually do anything. 🙂
cat <<“EOF” > /usr/local/bin/check-UMS.sh
#!/bin/bash
# Put your script here.
EOF
chmod +x /usr/local/bin/check-UMS.sh
cat <<“EOF” > /etc/systemd/system/check-UMS.service
[Service]
ExecStart=/usr/local/bin/check-UMS.sh
EOF
systemctl start check-UMS
All that goes into a ‘Base’ ‘Custom command’.
Hopefully that makes sense…. the first part is the script that you would want to run, like what you posted. You can probably just put it into a ‘while’ loop and put ‘sleep 900’ at the end (to pause for 15 minutes). The second ‘cat << EOF…’ part is to make the systemd service, and the final line starts the systemd service, which runs the script.
