Hi, I monitor an application where my java client talks to a remote server. So far I got tcpdump to dump everything that comes from the server into a file. That includes a lot of network noise besides of the pure content. I suppose that are protocol informations. Is there a way to strip all the tcp/ip stuff off and get just the payload? Maybe there is another sniffer that manages this task better?

Well..I haven't seen such a tool that would only show you the payload. But then, what Kind of payload are you trying to see? With tcpdump you'll only see plain text, therefore the only payload you will be able to see is plain text transmissions. Try ethereal (it comes with SUSE). It's a graphical app with similar functions like that of tcpdump. HTH, Jorge

What sort of filtering are you doing? I often use Ethereal, which allows filtering on all sorts of things, including protocol and addresses.
Hi there I am looking for a list of ftp severs where I could find the suse 9.0, I have the boot cd, goes on ok but ftp.suse.com it's very very slow and I can't go on with that speed anymore, does anybody knows where I could find any server available with that distro thanks J

Why do you want 9.0? It's been out of support for some time, so you won't get any security updates for it

We need 9.0 because we handle this middle ware app that only works on that version I am afraid.

9.0 is the last SuSE version that had a default 2.4 kernel (the 2.6 kernel was optional); starting with 9.1, only the 2.6 kernels are available. Do you perhaps have some funky kernel dependencies in this?

Actually tcpdump doesn't filter at all besids selecting only frames coming from a certain ip-adress. AFAIK tcpdump usually just shows the headers but has the options -a -s 0 to expand the output beyond the frame headers. So I get a lot more than I want. Suppose a payload stream of a readable text like a book. In the ASCII output there is the text and unreadable ASCII stuff where I think it has to be protocol headers or trailers. Sometimes they split a word in two parts with gibberish in between.

It all depends on how you set the tcpdump options - it is certainly not limited to IP-address. You can filter based on type of protocol udp,tcp,icmp for instance), by interface, host, port - in fact, tcpdump is incredibly versatile.
