opened a file since Ethereal was started, it defaults to the directory
that the most recent file was opened in.
Or am I misunderstanding the question?

There's actually a preference now. The default behavior is to have it
"remember" which directory you last opened Note that changing the
working directory in the shortcut before may have caused SNMP not to
work properly.

Sort of. You can generate a "Conversation List", which will let you
sort by number of frames/bytes total or in a given direction.

Mine does that too as long as I have the asn1 plugin installed. I'm not quite sure what file it's looking for, and it won't let me continue without a valid file. I'm guessing this is a relatively new change (with at least several bugs, several of which include not playing nicely with Windows) but
Easy to do in Ethereal provided that you can build a filter that will
match the symptom or event that you're looking for. I do this all the
time to find interesting events.
To use your example, you'd do this to mark all TCP ACKs that took longer
than 50ms to occur in a red text (bold or not-bo

Hi all,
I find it exceedingly helpful when looking at SMB and ONC/RPC-based

I've been looking through other dissectors, lik
Since there are actually two fields matching tcp.port (source and destination address), your filter will only exclude traffic if BOTH ports are 3389.
Instead, try !(tcp.port==3389), which will exclude traffic if EITHER port is set to 3389.

No such document exists that I'm aware of (though the man page covers a

I believe that libpcap on Linux has a limitation that doesn't allow

Hi Ferdinand,
It is fairly easy to filter on CIFS traffic only - simply use a filter
of "smb".
This will filter on only packets which Ethereal has determined to be
CIFS-related, including TCP ACK-only frames, etc.
It WON'T filter on traffic that may related to CIFS but not CIFS
