Any limitation on number of socket files in HP-UX

[avsrini]

Hi,

Is there any limitations in number of socket files created in HP-UX?

I belive these files are written to /tmp fs.

Thanks in advance

Hi Srini,

These files are not written in /tmp.

Take a look at this thread,

You can check out /var/spool/sockets/

socket files can be written temporarily in /tmp fs. Generally they are written in,

/var/spool/sockets/ location too.

Check as,

find / -type s to get socket files.

Socket related parameters are as,

# ndd -h supported | grep socket
ip_enable_udp_bcastrecv - Controls receiving of broadcast packets by UDP sockets
socket_buf_max - Sets maximum socket buffer size for AF_UNIX
sockets.
socket_caching_tcp - Controls socket caching for TCP sockets.
socket_qlimit_max - Sets maximum number of connection requests
for non-AF_INET sockets.
socket_udp_rcvbuf_default - Sets the default receive buffer size for
UDP sockets.
socket_udp_sndbuf_default - Sets the default send buffer size for
UDP sockets.

For tuning or collecting information then,

# collect information
# ndd -get /dev/sockets socket_buf_max
262144

# Tuning:
# ndd -set /dev/sockets parameter

For permanent effect set it with /etc/rc.config.d/nddconf
