Dear All,
i have a problem with my squid proxy.. suddenly its performance decrease and i never get the speed i expect from my squid box, and when i tail to access.log i find a weird line of information there,, please find it below :
1115668842.640 14680 61.224.206.211 TCP_MISS/200 824 CONNECT 205.188.156.185:25 - DIRECT/205.188.156.185 -
i found thousands of line similar to this one, even, i dont know the source ip address, destination or even the direct destination !! the 3 ip addresses doesn't belong to my network at all and all are blocked from the squid.conf file, plus why the destenation is trying to make connection on port 25 !!! ? such port is also blocked with the Safe_ports rule !
port 25 is not allowed on my linux box , so how this ip can hack to my squid box and through my squid can open a session to port 25 on the destination ? and how i can block this from happening ?! its killing my squid box performance
Best Regards ,
Can you firewall the proxy off from the rest of the internet and only allowing your network to hit it?
