have you installed the lmbench package ?
(In reply to comment #2)
> have you installed the lmbench package ?
# rpm -q dt lmbench stress hts
the lmbench package you're using is obsolete, which installs the binaries into "/usr/lib/lmbench/bin/i686-pc-linux-gnu/":
<15:10:32 kun@yk>$ rpm -qpl lmbench-2.0.4-2.EL5.i386.rpm | grep lat_tcp
we have upgraded lmbench to version 3.0a7 long time ago, which installs the binaries into the standard "/usr/bin/":
<15:08:12 kun@yk>$ rpm -qpl lmbench-3.0a7-6.EL5.i386.rpm | grep lat_tcp
please switch to lmbench-3.0a7 and see if this issue still exists, the latest lmbench package on RHN should be lmbench-3.0a7-6

Updated lmbench to 3.0a7-6.EL4, then network test failed with "tcp bandwidth test failed" error.
error is "bw_tcp errors: socket connection: Connection refused"
plesae make sure the firewall is turned off on both machines and the "hts server status" shows all the proper services are running on the network server.
The firewall was turned off on both machines. I updated lmbench to 3.0a7-6.EL4 on hts server machine, then re-run network test passed. Closed this bug.
