socket connection

[Wilfred Chau_1]

What is the maximum number of TCP socket connection allowed on hpux?

is it controlled by tcp_conn_request_max?

Hello

if you run #netstat -a to show active socket connections

Run ndd -h tcp_largest_anon_port to find the maximum - it is 65535

I'm not sure that number of ports has something to do with it. AFAIK, you can open as many sockets you , as long you have enough file descriptors available for them in the systems (kernel parameter "nfile").

Of course it's also depends on the program that handles the cconnection, but if we'll imagine that every program can handle unlimited number of connections, then it depends on number of FDs.

Wilfred,

It's controlled by "tcp_largest_anon_port".

You can determine the max number of available socket connections with ndd:
============================================
# ndd -h tcp_largest_anon_port

tcp_largest_anon_port:
Largest anonymous port number to use. [1024, 65535]
============================================
Output indicates that max no. of available sockets under hp-ux (32 bit) is 65535.

regards!

yes you have to take a look at these parameters nfile, maxfiles and maxfiles_lim.
