Here's my chance to put in a plug for my favorite network utility:
good old ngrep.  You can do amazing stuff with ngrep if you want, but
I normally just use it as an instant cli packet sniffer by typing
'ngrep' (as root) and then watch the packets whiz by on my terminal.

I took a peek with ngrep and also with wireshark but it's still not obvious whether compression is actually being used.  My connection to supernews is SSL enabled so all I see is nntps traffic.  That's why some visual feedback would be helpful.  I believe that it IS using compression but I can't prove it.

Hi Chris.
xzver uses plain old nntp, so you would get a compressed binary stream, as with gzip. The only indication whether or not it worked would be hidden in the response code. As pan gets its headers from all servers, an indicator wouldn't make much sense. Trust me, xzver is working. If you want to take a look, look into nntp.cc and break after the xzver command was issued. You should get a response line and then some yenc-encoded lines.
Giganews gzip compression is somewhat different: It uses a numeric response code and then spits out a binary blob ended with a single ".\r\n".

Cheers.
