- Just to second the comment, this really would be a very nice tool to
- have on my HP. My interim solution is to use a colleague's Sun (which
- HAS tcpdump ALREADY) in an xterm opened onto my HP 730.

- The tcpdump(8) tool is not used quite so much as ping(8) or
- traceroute(8), but it IS widely used by administrators of TCP/IP
- networks. I think of it as a tool that doesn't compete with a full
- blown network analyser but rather as one to narrow down the location
- of my problem (os, application, networking code, or the network
- itself) to help figure out whether to pull out a network analyser. In
- a previous life when my life was more operationally oriented, I
- depended on it. Now it would be very helpful in my research.
-
- If someone with access to the kernel sources were to port tcpdump(8)
- to HPUX/HP-BLS on the 7xx series platforms and anonymously donate it
- to the InterWorks archive, a lot of us users would be most grateful.
- Based on my understanding that the HP kernel uses networking code
- mostly derived from BSD 4.3+tahoe/reno, porting tcpdump(8) should not
- be a very hard problem (say 3 man-days) for someone with access to the
- kernel. I believe the canonical source archive for tcpdump(8) is
- ftp.ee.lbl.gov (I could be wrong). It is possible that someone at LBL
- has ported it already to 4.4 BSD running on an HP workstation.
