Re: [squid-users] Unable to increase file descriptor

Dear Yang,

I know the site that you sent to me, but I don't quite understand. First
because my squid comes with my FC2 distribution, I did not compile or
build it. Meaning the following steps doesn't apply to my case?

    * Before configuring Squid run "/ulimit -HSn ####/" (where #### is
      the number of filedescriptors you need to support). Be sure to run
      "make clean" before configure if you have already run configure as
      the script might otherwise have cached the prior result.
    * Configure, build and install Squid as usual
    * Make sure your script for starting Squid contains the above
      /ulimit/ command to raise the filedescriptor limit. You may also
      need to allow a larger port span for outgoing connections (set in
      /proc/sys/net/ipv4/, like in "/echo 1024 32768 >
      /proc/sys/net/ipv4/ip_local_port_range/")

Thanks for your advice anyway!
