There isn't such a thing as a package of tools for the Sysadmin or a
network QA person to use. At least not in the public domain that I am
aware of. What I have done is to collect the tools available on the
net and package them into a network test package. The goal (my goal)
is to have a package that can do several things:
1. Validation - network protocol, network function calls (sockets,
STREAMS, RPC/XDR).
2. Performance - monitoring, throughput (FTP, NFS, etc.)
3. Monitoring - this is more for trouble-shooting and to watch
out for potential problems.
I haven't found all the software I needed yet, but have found a number
of useful tools. The only problem is that many (most) are written for
Suns and needed a lot of porting to run on System VR4. I've ported a
number of them and in the process of porting the rest (when I can find
time :)). A co-worker is adding a Sun NIT workalike into our version
of SVR4.
Here is a list (not comprehensive):
- arpdump Examine arp packets
- chknfs Monitor NFS network
- nfsstone Benchmark NFS from Encore
- nhfsstone Benchmark NFS from Legato
- tcpcon Util for using pty on TCP
- tcpdebug Util (menu driven) for looking at TCP connections
- tcpdump An etherfind clone from Van Jacobson
- traceroute Util to trace route of IP packets
- ttcp Benchmark TCP throughput
If there are something I missed above, please let me know. I'll be
glad to maintain the list and post it every so often.

Personal opinion of course, but they are life savers, not to mention time savers.

> [network analysis tools] Check out RFC 1147: FYI on a Network Management Tool Catalog: Tools for Monitoring and Debugging TCP/IP Internets and Interconnected Devices It is a farily long list of both no-cost and commercial network management tools. Check also nnstat (ftp venera.isi.edu.) It is a fairly versatile statistics collection program. It uses "scripts" that tell it what you want to know. Neat and slightly complex; you need to read the manual. Nnstat runs only on Sun 3's, Sun 4's and IBM RT's. > A co-worker is adding a Sun NIT workalike into our version of SVR4. > ..
