Squid Proxy Server help needed

post #1 of 22

I am not sure what I am doing wrong, but any help would be much appreciated.

As I mentioned, when I use firefox, and set the network (proxy) settings to the IP Address and port number for an http proxy, it fails to either translate the website, or pass traffic through (not sure which).

If you want to use a Proxy server for outgoing Net connections than there is nothing like Squid. I would not use Apache as a proxy server for outgoing connections.

try a telnet to the proxy port , also check apache config hmm IIRC apachectl config something like that it should tell you if there is any error in httpd.conf , I am not too sure of the command as its been quite a long time configuring apache and stuff.

I would still suggest use squid.

Can you even use Apache like that? Usually those kind of proxies are browser based.

I'd go with Squid as well.

Well, I installed squid, and checked the acl's that pertained to local are networks and modified them so I could test it out:
squid.conf
access.log

With the resulting error message in the browser:
Quote:
ERROR
The requested URL could not be retrieved

The following error was encountered while trying to retrieve the URL: http://www.overclock.net/

Access Denied.

Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.

Your cache administrator is webmaster

Generated Sat, 31 Mar 2012 17:30:42 GMT by server (squid/2.7.STABLE9)

Where as if I go to an https site, it just flat out refuses the connection.


EDIT:
Also, would it be possible to run squid overtop apache? Or use apache's proxypass to have it run over a fqdn like: http://www.example.com/proxy

you need to create an acl for your network and also allow localhost but deny access to outside network so that they do not use your proxy, i am sorry i could have helped more but i don't recollect everything as i am not in touch with linux much.

hmm i think 1st create the acl and then allow that acl name

That should be included already in the squid.conf file. Should be lines 609 through 617. Unless I did it wrong. Was under the impression I could just bundle more things into the localnet group.

It is defined?

work and school isn't defined, only because it isn't on a private address, and I don't know the subnet mask for that. Everything else is fine:
acl localnet src 10.0.0.0/8 # RFC1918 possible internal network
acl localnet src 10.10.10.0/24 #Home Network
acl localnet src 10.10.11.0/24 #Guest Network
#acl localnet src 172.16.0.0/12 # RFC1918 possible internal network - Not used
#acl localnet src 192.168.0.0/16 # RFC1918 possible internal network


The /24 represents 255.255.255.0, so I don't know what you mean I need to define it.

You need to define your own network acl e.g 192.168.0.1/24 or 192.168.1.1/24 , are you on a linux machine right ? then in the terminal you type ifconfig or ip that would show something like

eth0 : 192.168.1.2 255.255.255.0 (this is 192.168.1.1/24)

eth1:

lo :


depending on how many ethernet cards you have in your linux system.

if on a windows system than you just to click on the network icon on task bar and find out your network.

do not look at the default provided in squid.conf you need to assign an acl which matches your network.

Hmm as I do not remember much there might be something for https an acl for that i am not sure. you may find it confusing at first but if you just read the ACL in squid.conf it will become clear and squid by default uses port 3128 (which you can change).

Again, check the lines #home network and #guest network, or check the post prior to yours.

I am not looking at the lines in squid.conf. My main network is on a class A 10.10.10.0 assignment, my guest wifi network is on a 10.10.11.0 assignment. It has been addressed correctly.
Using 10.10.10.1/24 and 10.10.11.1/24 in the config
