Hi,

you can check /var/adm/syslog/syslog.log

another log for network disconnection , console logs, chassis code buffer:
CL , SL .

Nejad,
If you are under SG environment network related logs will be captured in syslog .

Other than this you can use netfmt tracing and logging facility to check nettl.LOG00 file to see network related errors and connection drop / disconnection related messages,

Ex: To see the last 50 records of the log file:
# netfmt -t 50 -f /var/adm/nettl.LOG00

More about netfmt pls. check:
http://docs.hp.com/en/B2355-90681/netfmt.1M.html

Cheers,
Raj.

Hi again,

On second though, better way to use nettl utility on HP-UX as some people mentioned. For an example I put steps :

# nettl -start
Initializing Network Tracing and Logging...
Done.

# nettl -traceon all -entity all -f /tmp/mytracefile
nettl : The trace/log file name specified is too long to append
the file suffixes. The file name has been truncated
to the following: /tmp/mytrace.

## After a day later ,you can stop tracing and probably you will have more than one trace file. . .

# nettl -traceoff -entity all
# netfmt -N -f /tmp/mytrace.TRC000 > /tmp/trace0

# netfmt -N -f /tmp/mytrace.TRC001 > /tmp/trace1

# nettl -stop

# pg /tmp/trace0 # To check first file
# pg /tmp/trace1 # To check other file
