Session tracking should ignore when IP to monitor is changed

[xerxes]

Seeing behavior where, in an effort to make it easier with multiple client's being visible to ShowEQ, I enable Session Tracking. However, when I want to swap monitoring to another IP that it sees, changing the monitored IP does not pick up any new sessions, since it's locked onto the other one.

This would normally make sense, however, if I am changing the IP to monitor, that would mean I want it to monitor that IP. Now, you have to disable it, then enter the new IP, then re-enable it.

Nice catch!

I can't test it right now, but I think it's a simple fix. Mind trying this patch and letting me know? Apply it with
patch -p1 < patch.txt

Tested and recompiled and reinstalled. The patch applied successfully, however, it does not detect the new IP when zoning. Additionally, it no longer detects the original client either. So it's letting it go, but not seeing the zone change from the new IP.

Hmm...

Assuming you're compiled with debug enabled (the default), then after you set the IP, you should see a message about the PCAP filter changing, and that should have the new IP in it but not the old session port. Can you confirm?

[xerxes]

Correct. The port is changing.

I don't think is related, but I also tried setting Real Time Thread as a part of other testing. The process is running as root, but is unable to enable that. That may be broken.

OK. Thanks for testing and the additional info. I'll have to try to test it here and see if I can figure out what's going on.

I haven't seen any issues with toggling realtime. If you want, the attached patch will cause it to print the return value from the underlying function, which we can look up and see why it doesn't like it. Apply with -p1

Warning - Failed to set capture thread realtime with error 1.

My best guess is because it's running in a container, it doesn't have access to something on the host system.

Yes, errno 1 is EPERM - operation not permitted.
