Weird connection problems with Gmail and Facebook
I have this kind of problem:
Looks like the same question was asked here, but without a solution. I followed the instructions in the link to check SSL, but it was already set up correctly. I have a relevant Wireshark capture, but understand very little of it. I'm pretty much out of ideas. |
have you tried traceroute, ping and other low level tests to reach those hosts?
|
Yes, I can ping them ok, I forgot to mention it. I haven't tried traceroute. Should I?
|
I would do that, also for working environment
|
This certainly sounds like an SSL related problem. You could try out some SSL only sites to confirm this. Try encrypted.google.com
The packet capture might also provide insight into what is happening/not happening. |
Hello,
here are the outputs from ping, traceroute (and ipconfig/ifconfig for good measure) from my computers. Ubuntu (desktop, not working): Ping Google Ping Gmail Ping Facebook Traceroute Google Traceroute Gmail Traceroute Facebook Ifconfig Xubuntu (laptop, working): Ping Google Ping Gmail Ping Facebook Traceroute Google Traceroute Gmail Traceroute Facebook Ifconfig Windows 7 (same computer as Ubuntu, working): Ping Google Ping Gmail Ping Facebook Traceroute Google Traceroute Gmail Traceroute Facebook Ipconfig I'm sorry, I don't have access to the computer right now so I can' check your suggestion, iamwilliam. I'll try that as soon as I get the chance to do so. |
Looking at the post above, it seems a bit confusing. Here are the outputs in code tags, hope it helps:

I solved this by lowering MTU as described here:
http://www.ubuntugeek.com/how-to-cha...ntu-linux.html Basically I dropped 10 from the default value (1500) until it started to work and then made the necessary change to /etc/network/interfaces. |
