Favorite network stress tests?

Favorite network stress tests?

[Stephen Hemminger]

Does any one have a favorite network stress test?
There are the usual benchmarks like ttcp, netbench, are there others?
NFS?

pktgen is good for testing/abusing drivers, below the IP stacks.

Here are some places to look/try:

http://www.colorfullife.com/~manfred/net-stress/net-stresstest.txt

ftp://robur.slu.se/pub/Linux/net-development/pktgen-testing/
(is this the same pktgen that is now in 2.5 kernels?)


fsx-linux from Dave Jones:
  http://www.codemonkey.org.uk/cruft/
or from Andrew Morton (used to be here at least):
  http://www.zip.com.au/~akpm/linux/ext3-tools.tar.gz
This is a filesystem test and has been known to find problems, both
locally and over NFS.

netperf is another for TCP/UDP stream and req/response
kind of stuff. There is support for sendfile, IPV6, etc.

Since Stephen is bridge maintainer now I assume he might like esic from
the isic package. It can send packets with random source/destination
macaddresses.
There's a bunch of other small programs in that package as well.

Then there's testlvs and of course diffrent scriptkiddieprograms for
syn/ack/udp/fragment floods with random ip's and ports, they stress the
routingcache and conntrack a lot.

Actually by Apple Inc. I just made it compile under Linux.

Yes, I was just pointing to a location for it, not trying to give
credits.  I'm hoping (and verified) that the original source of it
is in the source file.

 No I've asked for testers but haven't got any response at all so it's not 
 pushed towards 2.5 yet.
 
 Cheers.
