Re: [squid-users] Squid3 issues

Hi Amos,
Thanks again for your reply, I have tried these two links, I have used them
for one server at a time, or maybe the issue is that I was trying to access
the backend Server which is currently running in virtualhost mode and holds
the 3 websites.

As I said before I have completely uninstalled the previous Squid, I
reinstalled it again this time, configured it and compiled it (manually)
I had some issues with permissions, first the cache logs and then the swap
file directory but it's all sorted.
Now when ever I start Squid with
Squid -NCd 10
I check if everything is running ok, so I get this warning:

ClientParseRequestMethod: Unsupported method attempted by : 111.118.144.225
This is not a bug. see Squid.conf extension methods
ClientProcess Invalid Request.

Let me just point out that first I have no idea where this IP originate
from, I tried Dnsstuff to figure out where it's coming from, I am not sure
if it's a Google crawler or someone else, the information wasn't clear.
But it's definitely not one of my IPs
Second, the proxy at the moment is behind a router and is not connected to
any of "Local" clients yet, I wanted to run it first before I can connect it
as a "Proxy-Router"
How can I prevent this from accessing it because it's persisting connection
it will soon cripple the server.

Does anyone know who owns this IP address please? 111.118.144.225

All I got as info is this
Location: Cambodia [City: Phnom Penh, Phnum Penh]Maybe I need to block their
IP if I can.At the moment the proxy server is set as a standalone machine
connected through a router so I can't understand why is it gettingthese
requests, from outside.Any ideas please?RegardsAdam----- Original
