since two days I can't connect to facebook any more. All other pages work. I tried it from Firefox as well as from Chromium (both on ubuntu 12.10). The strange thing is, that it is working on Windows.

I also already changed the MTU to 1492.

I run curl, too:

* About to connect() to port 80 (#0)
*   Trying
* connected
* Connected to ( port 80 (#0)
> GET / HTTP/1.1
> User-Agent: curl/7.27.0
> Host:
> Accept: */*
* additional stuff not fine transfer.c:1037: 0 0
* HTTP 1.1 or later with persistent connection, pipelining supported
< HTTP/1.1 302 Found

< Connection: keep-alive

* Connection #0 to host left intact
* Closing connection #0

Has anybody an idea, what it could be?

Thank you!

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

What does "can't connect' mean? What happens in the two browsers when you try to load Is only affected? What happens if you try Can you bring up a terminal and try ping -c1 What ip-adress, if any, is in the result? Why have you been changing the MTU? There's very rarely any reason to meddle with such details of the network stack for non-professionals. – user50849 Jan 29 '13 at 15:50, and are bringing a timeout. The result of the ping is the IP, (which should be right, or?). I changed the MTU because I found a similar problem here: link – Lukas Jan 29 '13 at 16:08
Hmm, what if you curl -v in the terminal? Might be a lot of text, please update the question, instead of posting as comment. – user50849 Jan 29 '13 at 16:23
the curl output says the connection worked, status 302 means you got redirected to the https version. This is a problem with chromium/firefox, not your network. – ImaginaryRobots Jan 29 '13 at 16:47
This shows the connection is working; as @ImaginaryRobots said you've just been redirected to HTTPS. Now run curl -v and paste the output – jackweirdy Jan 29 '13 at 16:53

Note: This would remove all the custom settings, bookmarks, history, cookies, saved passwords and co.

  • Open a terminal and run rm -rf ~/.mozilla
  • Open Firefox and go to Facebook again.

This might help:, which is a chat link from the question: Facebook not working on Ubuntu 12.04.

Won't this remove custom settings, bookmarks, history, cookies, saved password & co.? Isn't there a less destructive solution? – Andrea Corbellini Jan 29 '13 at 16:49
Ofcourse, it would. – green Jan 29 '13 at 16:49
wouldn't it be better to specify it explicitly then? ;-) – Andrea Corbellini Jan 29 '13 at 17:05
There! In your words :) – green Jan 29 '13 at 17:10
Hey, thank you, that helped! Do you know why that problem occours? I had also in mind, that it coult be connected with the https. But other https sites worked, too. – Lukas Jan 29 '13 at 20:49
