Hi, Hello all, I compiled and installed squid on debian 6 server. I want to use authentication in proxy so i configure squid to use mysql. I followed /ConfigExamples/Authenticate/Mysql tutorial of squid-cache wiki. Now in my server, /usr/lib/squid/squid_db_auth --user someuser --password xxxx --plaintext --persist this test runs ok, now in my pc i run, ssh -f root@xxxxxxxxxx -L 3128:domain.com:3128 -N then i run, chromium --proxy-server="localhost:3128" but it's not working , i get the error, No data received Unable to load the webpage because the server sent no data. Here are some suggestions: Reload this web page later. Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data. So think the problem is that i dont / cant use authentication because i cant see any option of providing username and password in chromium or firefox or system proxy setting window. How can i provide the username and password to proxy server ? My System info, server : Debian 6 32-bit processor : 300MHz RAM : 256MB pc : opensuse 11.4 kde 32bit processor : core 2 duo 2.8GHz RAM : 1GB looking to get a solution from you guys :) Thanking Sarim Khan
