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.
