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.?
