iperf UDP fails

[Eric Boyd <eboyd --at-- internet2.edu>]

Hi,

I'm having a problem with iperf v1.6.5 on FreeBSD v4.6-STABLE.

On the client:

bash-2.05b$ iperf -v
iperf version 1.6.5 (13 Jan 2003) pthreads
bash-2.05b$ iperf -u -c foo.bar.edu
------------------------------------------------------------
Client connecting to foo.bar.edu, UDP port 5001
Sending 1470 byte datagrams
UDP buffer size: 9.00 KByte (default)
------------------------------------------------------------
[  6] local 192.168.1.162 port 1158 connected with 192.168.1.161 port 5001
write failed: Connection refused
[ ID] Interval       Transfer     Bandwidth
[  6]  0.0- 0.0 sec  2.87 KBytes  1.05 Mbits/sec
read failed: Connection refused

On the server:

bash-2.05b$ iperf -s -u
------------------------------------------------------------
Server listening on UDP port 5001
Receiving 1470 byte datagrams
UDP buffer size: 41.1 KByte (default)
------------------------------------------------------------
connect UDP failed: Invalid argument
bash-2.05b$ iperf -v
iperf version 1.6.5 (13 Jan 2003) pthreads

This same test on the same machines works fine with v1.1.1 of iperf.

Any ideas? Am I doing something wrong?
