Script not working

[OxMarco]

I have tried to execute the script on an Ubuntu 12.4 VPS and setting the environment variable "http_proxy" causes all connections to be blocked. I have opened all ports in use looking at netstat -ntlup but still, even when trying to ping a website, it reports:

Connecting to 192.168..:3400... failed: Connection refused.

How to fix it? Thanks

P.S. Around the end of the script there is a " missing in an echo statement

Hi and thanks for reporting! Can you provide the commands and full errors please? Looks like squid is either unresponsive or blocking you. Can you paste the output of the netstat command and your squid.conf please? Also, http_port is not what should be exported, it's http_proxy but i think you did it correctly on commandline, otherwise the error would not be there ;-)

Hi, thanks for your reply.

I tried reinstalling on a clean VM (Ubuntu 12.04), I set the global var and I keep getting:

curl -I www.google.com curl: (7) couldn't connect to host

which automatically solves once I unset "http_proxy".

Netstat output:

I opened all the ports listed (on TCP protocol only) on the VM firewall.

The squid.conf, untouched, is as follows:

Thank you

I think i see what is causing the problem. In squid.conf the http_port ip address is propably not the external ip of your vm. Can you try swapping it and reload squid after that?

[OxMarco]

Still can't connect I also tried to set it to the localhost ip (127.xxx) and to the local network ip (192.xxx).

--- updates --- Ok, I set http_port to 3400 in squid.conf and it seems I can connect via cURL but I get the following response: ` <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

If I connect from PC to the proxy server, squid seems to be working as it blocks certain websites but the IP and headers sent are the same as normal browsing. I block headers like User-Agent with: request_header_access User-Agent deny all

@jake9050 hello, any news? Thanks
