I am running a 4.1-RELEASE i386 system and I am trying to increase the
maxsockbuf size so I set it in /etc/sysctl.conf like this:
kern.ipc.maxsockbuf=524288
And on bootup I see
kern.ipc.maxsockbuf: 262144 -> 524288
but when I try to use a larger buffer I get:
pirzyk@snoopy:/sys/kern
10>ttcp -r -w512
ttcp-r: buflen=65536, nbuf=2048, align=16384/0, port=5001, sockbufsize=524288 tcp
ttcp-r: socket
ttcp-r: setsockopt: sndbuf: No buffer space available
errno=55
But this should work. Seems the kernel is keeping the old value of
262144. Now I can change it in /usr/include/sys/socketvar.h (SB_MAX)
and rebuild the kernel but I do not think this is what was designed.
