Re: [cobalt-users] checking mail error

["Fragga" <fragga@xxxxxxxxxxxx>]

could be a number of things.

have u checked /var/log/maillog for clues if so has it logged timeout and
any reasons ?

possibly a firewall setting his end ? Is he getting errors his end or just
timeout ?

you could quickly sniff the session to see what the conversation was like..
download a copy of snort from snort.org install it then simply run ( as
root )

$ snort -vde host <his_ip_address>

get him to do a send and receive and watch the packets or log the packets
using

$ snort -vde host <his_ip_address> > output.txt

or if you cant be bothered with snort use tcpdump which is installed by
default

$ tcpdump -vvv -s 0 -X host <his_ip_address>
