maximum number of tcp connection

[kholikt]

I am checking the parameter of my hpux 11.00 server.

tcp_conn_request_max is only set to 20 by default. I was surprise the number is so low. I think solaris by default is 1024.

What is the impact of this parameter if the server is not a web server.

Hi,

tcp_conn_request_max specify Maximum number of outstanding inbound connection requests. default will be 20 connections, you can increase the value

Hi actually I want to know maximum number of established connection allowed for a server not the outstanding connecntion

That's going to be either whatever maxusers is set to or the number of pty's you have created, whichever is lower. There may be other restraints with kernel parameter settings regarding resource allocations that result in no more free resources to allow users to login, YMMV.

Minor Correction

Ports upper limit is 65535, you will hit system resources before that which are controlled by nfile and maxfiles. Everything is a socket in Unix :-)
