As of around May 2018,  there were various reports of issues with Citrix at SLAC.  The Citrix client wasn't completely broken for all, but it was not ideal for many, and broken completely from some.

With the release of a newer firefox, the situation with Citrix on Rhel6 became even worse. The version listed on this page stopped working. Later versions were tested and found to be broken too.

If you have some other way of getting to Citrix beside rhel6, or the applications provided by Citrix, we ask that you use those methods.

If this is not possible for you then please feel free to submit a ticket to unix-admin. When submitting a ticket, please reference this page.

We continue to look for avenues to make this work on Red Hat 6 at SLAC. If you have a ticket open with us already regarding citrix, we'll be reaching out to. If we failed to reach out to in a timely manner, please let us know.

The Citrix client is no longer supported on RHEL5 systems at SLAC.

Tracking one issue with the upgrade installation client (ICAClientWeb-rhel-13.3.0.344519-0) and kernel. Have seen this not work on system, even after restarting browser. The solution was to uninstall the version, and re-install the client again.
