CirrusHow unique are session IDs supposed to be?
Hiya, newbie Firepass (FP) user here. I'm auditing logins to our FPs via syslogs and I was hoping I could rely on the "Sid" reported during logon and logoff events to be good ways to track sessions. That does not appear to be true and I'm wondering if what I'm seeing is what I *should* be seeing or not.
We're running 6.0.2 by the way. See this example of what looks like two distinct logins by a user on the same day and the SID is the same for two distinct sessions:
Jul 24 20:16:48 1.2.3.4 security[4776]: [foobar@authtype] User foobar logged on from 4.5.6.7 Sid = fd3cf
Jul 24 20:28:42 1.2.3.4 GarbageCollection[9232]: session 'fd3cf63b065a8398d3dc9c501682be70' is expired due to inactivity. User may have logged out improperly.
Jul 24 20:28:50 1.2.3.4 security[9083]: [foobar@authtype] User foobar logged on from 4.5.6.7 Sid = fd3cf
Jul 24 20:49:42 1.2.3.4 GarbageCollection[16585]: session 'fd3cf63b065a8398d3dc9c501682be70' is expired due to inactivity. User may have logged out improperly.
Can anyone share what the SID is a hash of? Thanks.

Hi Michael,
Welcome aboard! FirePass uses an abbreviated SessionID when sending logs out via Syslog/System Log facility. It used to send out the full SID but a few versions back this got changed to the abbreviated format. Probably your best bet is to export the Session Report (or Logon Report) from the AdminUI cause that should give you what you need.
In regards to what the SID is a hash of - your guess is as good as mine...that would come under the category of 'F5 black magic'.
Cheers,
Mal
Mike_HoThanks Mal for the response! I haven't checked back here in a while but I'm happy to see someone wrote back. What I was working on before was automated reporting so downloading additional logs manually isn't my cup of tea, but it is helpful to know that info is there should I need to look it up.
Mike- mal_57091Hey Mike,
Sure thing! No problems at all. The most useful scripting language (I've found personally) to use with FirePass is cURL. I use to write script that log into the admin UI and do all sorts of stuff. If you had some time you should check it out and see if can do what you want automagically! :-)
Cheers,
Mal
