Hi All,
I am using normal socket program in c in HP-UX.I want to know at a time how many client are connected to socket. Is there any command using which i can check how many user are connected to socket ?
Thanks in advance.

Shalom,

Funny, I just read this in a performance book for HP-UX last night.

netstat -aAn

The man page for netstat will allow you to refine this output.

netstat -aAn will not work as -A is not an option in the list of switches for netstat. But you can do

netstat -an > /tmp/mytempfile

then edit this /tmp/mytempfile and look for a pattern saying "Active UNIX domain sockets". After this line, it is all sockets. It is upto you to determine what is connecting to where and then count them.

For a TCP socket, there is by defintion only one client "connected" to a socket. There can, of course be many clients connected to a service residing at a (well) known port number.

For UDP it gets a bit less clear.

Lsof may be useful for you:

lsof -i@ip_address:port_number
lsof -i@192.168.30.80:1521
