Trying to use nettl or trying to install tcpdump

[Karim Manji]

We have just recently moved over to the HP-UX platform form IRIX. I have been was using tcpdump to track where our xml transfers were failing. The tcpdump command I would use is
"$ tcpdump -l -v -v -v host IP_Address > /tmp/capture1.txt &".
I have been trying to find out how to do same thing using nettl, I am not finding it easy, its been a long day.
Can anyone tell me how I can use nettl to give me the results, that I got using tcpdump.
OR (I downloaded tcp dump, onto the HP server) If someone would kindly in explain how to install it on the server. I have never downloaded a unix program from the Internet.

TIA

See man tcpdump http://hpux.connect.org.uk/hppd/hpux/Networking/Admin/tcpdump-3.6.2/man.html

you use something like the following script to trace
network traffic between your host and some other destination :

host=$1
pc=$2
echo "Tracing with $host"

rm /tmp/conslog.opts > /dev/null 2>&1
echo "FILTER IP_SADDR $host" >> /tmp/conslog.opts
echo "FILTER IP_DADDR $host" >> /tmp/conslog.opts
nettl -start
nettl -traceoff -e all
nettl -tn pduin pduout -s 1024 -e lan100 | netfmt -c -N
/tmp/conslog.opts

If you're already familiar with tcpdump, you can download a precompiled version from hpux.cs.utah.edu (or nearest mirror). You'll have to get 2 packages : libpcap and tcpdump. Install using swinstall.

Sorry, I am no more further.

Vincenzo, I am familar with that man page, but I may be missing something, no where do I find instructions that tell me that once I have the file on the HP Server, which directory to place it on, how to unzip it, etc. Detail information on installing it.

Rainer, I was really excited to try the script you posted. I tried it, but no luck. However, I am tring to learn nettl so I will keep plugging away.

Laurent, I downloaded
"libpcap-0.6.2-sd-11.00.depot.gz" and
"tcpdump-3.6.2-sd-11.00.depot.gz". Do I have to place it in a certain directory? and Do I unzip these or do I just run swinstall?

I thank you for the help. I am going to keep plugging away.

You need to unzip and install them :
# gunzip libpcap-0.6.2-sd-11.00.depot.gz
# gunzip tcpdump-3.6.2-sd-11.00.depot.gz
# swinstall -s /path/to/libpcap-0.6.2-sd-11.00.depot '*'
# swinstall -s /path/to/tcpdump-3.6.2-sd-11.00.depot.gz '*'
# /opt/tcpdump/bin/tcpdump ...

Laurent,

Thank you so much, I now have tcpdump installed. There are differences in syntax, so I have to look over the man pages.

HI

I installed tcpdump 3.4 and libpcap 0.4, but when i want to run tcpdump with a simple command
"tcpdump tcp and port 23" the next error message
"tcpdump: can't find PPA for /dev/lan0"

Thanks
