[netperf-talk] Problem with TCP_RR on Sun: netperf: set_sock_buffer: SO_SNDBUF option: errno 132

[Alexander Vinokur]

Andrew, thank you.

Do you know something of this WARNING!

./netperf -l 300 -H snt5012 -t TCP_RR -i 10,3 -I 99,5 -- -r 4,4 -s 2M -S
2M

 

WARNING! getaddrinfo returned a protocol other than the

requested protocol.  Please contact your vendor for

a fix to this bug in getaddrinfo()

Thanks,
Alex Vinokur

Solaris defaults to a 1MB limit on TCP socket buffers.  Try
increasing tcp_max_buf.  Eg:

# ndd -get /dev/tcp tcp_max_buf
1048576

Try increasing it.

# ndd -set /dev/tcp tcp_max_buf 8388608
