Hi Carter... Probably a wrong time to ask... but, I was wondering about
something.
These two, entries....
-z Print Argus TCP state changes for each tcp transaction. Values are
's' - Syn Transmitted
'S' - Syn Acknowledged
'E' - TCP Established
'f' - Fin Transmitted (FIN Wait State 1)
'F' - Fin Acknowledged (FIN Wait State 2)
'R' - TCP Reset
-Z <s|d|b> Print actual TCP flag values. <'s'rc | 'd'st | 'b'oth>.
'F' - Fin
'S' - Syn
'R' - Reset
'P' - Push
'A' - Ack
'U' - Urgent Pointer
'7' - Undefined 7th bit set
'8' - Undefined 8th bit set
Now, the part I dont understand is the -Z <s|d|b> option, since it seems to
be telling us about individual packet information, not for a flow. Ie: a flow
doesnt have the Ack bit set, a packet does.. and there are multiple packets
per flow (usually :)). So, in a normal flows, say... a http transaction, what
does the output from this option refer to? Also, how does this tie into the
above -z command? Is -z meant to be used in a 'so far in the flow, we have
see the following activities', during the argus_flow_status record printing?
Thanks,
Chris
