Trace of traffic of network

[Marcelo De Florio]

I need a trace of network, how can I enable this feature in HP-UX 11.0 ?

Thanks

You can download TCPDUMP, or use the built in tracing for HP-UX. For nettl tracing, I attached a document that may help. For TCPDump, you can download that from

http://hpux.cs.utah.edu/hppd/hpux/Networking/Admin/tcpdump-3.6.2/

Hi,

nettladm is HP-UX's proprietary network tracing and logging administration manager. man nettladm for further information.

Alternatively, use the third-party tcpdump for network tracing.

Hope this helps. Regards.

/usr/sbin/nettl ?start see man nettl

After execute nettl -start, How can I view the log of package at network ?

[Berlene Herren]

If you are just using the nettl start, the file written to is /var/adm/nettl.LOG00.

This is a binary file, so you have to do a net format on it first.

#netfmt -f /var/adm/nettl.LOG00 > /tmp/log.out.

Then you can cat, view, vi or more the /tmp/log.out.

A real goot tool is ethereal which comes with a nice GUI and a lot of options. You can get it at the same site as the tcpdump tool. (See Berlene's post)

What can I execute to trace of traffic, from server to client ?

I execute :
nettl -tn pduin pduout -e ns_ls_ip -f /tmp/net.log


nettl : The tracing and logging facility has not yet been started
To start the facility, execute the following command:
/usr/sbin/nettl -start
If the problem persists, contact HP representative with the
following information:
Shared memory tables removed.
(shmget, errno 2: No such file or directory).

Why appear this message ?

Thanks

Make sure that NETTL=1 in /etc/rc.config.d/nettl

then run

/sbin/init.d/nettl start
