Restarting the SOCKS Proxy kills existing connections.
To restart the SOCKS Proxy under MVS when you are running it as a started task, use the following console command:
===> F SSHSP,RESTART
To restart the SOCKS Proxy in ISPF, enter the Tectia SSH Assistant option 4.3.3 TSXPR (Restart the SOCKS Proxy server).
You should see the following console message:
<USERID>ACTIVATED -F SSHSP,RESTART +SSZ3003I Command RESTART accepted
Tectia SSH Assistant options 4.3.3 TSXPR (Restart the SOCKS Proxy server) and 4.3.4 TSXPRF (Restart the SOCKS Proxy server, killing connections) are effectively identical.
