Our tl-support script still requires Python 2 and should be converted to be run in Python 3.
Tested this using: A) Fedora 33 (For the 'client') B) RHEL8 system for the 'support server' C) Fedora 33 (My workstation) Given Firewall restricting ssh connections from outside on the client computer (A). When Tl-support script used on the clients computer A towards the support server B. AND Worker C connects to support server with port given by client A. Then This grants access to computer A for worker at C.
Tested on Ubuntu 20.04: ✓ Using default (support.thinlinc.com) ✓ Using bad hostname ✓ Using explicit user and server ✓ Using explicit port
