Hi I am running squid 2-5-10 on red hat 2.4.21-4.ELsmp with 1 Gb memory. Before compiling squid I set ulimt value to 32000. I also set ulimit -HSn 32000 command in my squid startup script. I noticed if anybody launch dos attack on my network from internal network, squid stop responding to other internal users also. What is the solution for this. One user should not be able to use whole resources. Is there any way to control this? I read squid document for maxconn parameter. I set maxconn to 2 for testing purpose and I made more than 2 connections ( checked through netstat -tn ) from my browsers but squid was still replying me. What could be the reason of this?
