Hi Guys -

 

   I have a stunnel setup in a linux box kernel 2.4 Advanced sever release 2.1AS (pensacola) . I am trying to increase the number of file descriptors with which stunnel could handle.  So I did a ulimit -n 4096  for root and restarted the  stunnel process.

 

 Now in the stunnel logs i see,

 ..... FD_SETSIZE=1024, file ulimit=4096- > 500 clients allowed.

 

 

I dont completely understand the  relation between  FD_SETSIZE and file ulimit.   I also read that a single stunnel connection might use around 2 or 3 file descriptors.

 

So what is the cap on the number of file descriptors used by stunnel. To make it use , around 4096 file descriptors should i recompile the stunnel again with FD_SETSIZE set to 4096.?
