For Several days, the Internet did not work at my home. Multiple IP addresses were not reachable. First I thought that the problem is on name resolution service. Using tracert I could find that the packets could not forwarded by a router at a certain point of way. After a short search in google, I found out that this is a well known problem that occurs not for the first time. There was no any solution, for this problem. The only thing I could do is – wait.
Or maybe not? Of course not! Fortunately, my server, also at 1 & 1 is reachable. I am logged on Putty and tried to open a website with the help of lynx, that I could not reach from my home PC. That went smoothly. The viewing a web page using lynx is not a solution that I need. That’s why I decided to setup a proxy server. I had not any experience with proxy servers, that’s why I asked the Linux community for help. The help was quick, but as always too short. They recommended me a Squid proxy server. As a guide I should use “man squid“. I must admit, I hate manuals that are written in the style of “man”. So I searched for a short and understandable HowTo. Fortunately there are lots of them in the web. I needed about an hour to understand how everything works. The hardest part for me was setting up the password prompt. The location of program ncsa_auth was known for me and I could not find it with help of „find“ command. But when I found this program, I made the setup very quick. After this point I was able to use Internet and view any web site without a problem.
