Well, I submitted nettest to ports just after 2.2.5 was announced (so
it didn't get on the CD). Look on ftp.freebsd.org in ports-current/net.
It's some really cool (and old 1992, I think) software from Cray.
Basically, you start the server on one machine (nettestd) and on the
next run nettest something like:
proot horton:/aces/home/proot $ nettest -f -b 40k sentry 30k 100
Transfer: 30720*100 bytes from horton.iaces.com to sentry
Real System User Kbyte Mbit(K^2) mbit(1+E6)
write 2.6240 2.6167 (99.7%) 0.1667 ( 6.4%) 1143.29 8.932 9.366
read 6.5340 0.9500 (14.5%) 0.0500 ( 0.8%) 459.14 3.587 3.761
r/w 9.1580 3.5667 (38.9%) 0.2167 ( 2.4%) 655.16 5.118 5.367
100: 30720
Add somethings wrong here, because I should have 100 running here. Oh
great.
Anyway, it compiles easily on SunOS, Solaris and FreeBSD.
Paul.
