Living abroad and can't access Gmail or Facebook - help!
October 6, 2009 11:01 AM   Subscribe

I can search Google, read the news and view most websites, but specific sites like Facebook and Gmail won't load on my Mac Powerbook - I just get page load errors. Any idea what the problem is?

I'm a Canadian living in France temporarily, and I've taken my laptop from home with me. While here I'm using a shared internet connection at a school, and although I can do web-searching and such, Gmail and Facebook won't load, in Firefox or Safari (or even the crappy discontinued version of Internet Exporer I just downloaded in the hope that it might work). I suspect the problem is with my computer, since other people using the same network connection are able to access these sites with no problems.

The page load error message suggests I might have a firewall in place, but I've checked the settings and nothing seems to be enabled. That said, I'm not terribly well-versed in this stuff. As well, the local tech support guy gave my computer a thorough once-over and can't figure out the problem.

Any ideas? For what it's worth, I've used both Gmail and Facebook in Canada and elsewhere on this computer with no problems.

Go to the Network settings area, click the particular interface you're using (wireless, wired..) and look at the DNS settings.

Are they automatically set, or are they manually filled in? If they're manually filled in, remove them and try again.

DNS settings have been automatically yet, regretfully.

Also, it's an ethernet connection.

Try modifying the DNS settings and supply:

4.2.2.1
4.2.2.2

Sorry, no dice. But thanks for the efforts so far.

Go to a Terminal window and issue the following command:

nslookup facebook.com

What response do you get?

If you don't get an error message of some kind, select the first IP address in the response and try:

traceroute 69.63.187.17

What response do you get?

I had PeerGuardian installed and it borked some sites for me. Uninstalled it (kind of a pain) and the problems went away.

This was my question on the subject, FWIW.

I have no answer, but can tell you that my kid's macs had the same problem (GMail) for a while and I tried everything. It worked when I logged in as an admin, but not on their regular logins. Just another datapoint. (THe problem cleared itself up or I did something, but it went away and I cannot tell you why.)

What are the error messages?

Sorry odinsdream, my tech expertise is lacking - what's a terminal window? I'd like to try that option.

Here's the error message from Firefox, in its entirety:


Failed to Connect

Firefox can't establish a connection to the server at www.google.com.

Though the site seems valid, the browser was unable to establish a connection.

* Could the site be temporarily unavailable? Try again later.
* Are you unable to browse other sites? Check the computer's network connection.
* Is your computer or network protected by a firewall or proxy? Incorrect settings can interfere with Web browsing.

Ok, found it. There's no error message when I do the nslookup, but here's the response to the traceroute:

traceroute to 69.63.181.12 (69.63.181.12), 64 hops max, 40 byte packets

That's odd.. does anything happen after that last line for nslookup? It doesn't go further than that?

...traceroute... last line for traceroute.

You should see one line for each step towards facebook. The first line is the closest to you, the last line is facebook. Here's mine for example:

13  www-13-08-ash1.facebook.com (69.63.187.19)  39.697 ms  30.455 ms  29.492 ms
So, if you're not seeing anything further than the line you posted which contained 192.168.231.254, that indicates problems on your local network. Addresses starting with 192.168 are private, indicating that your traffic request is stopping before hitting the internet at large.

To make sure I understand correctly, here's my response to the nslookup:

Server: 10.137.5.130
Address: 10.137.5.130#53

Non-authoritative answer:
Name: facebook.com
Address: 69.63.187.17
Name: facebook.com
Address: 69.63.187.19
Name: facebook.com
Address: 69.63.181.11
Name: facebook.com
Address: 69.63.181.12
Name: facebook.com
Address: 69.63.184.142

I did the traceroute for 69.63.187.17 - is that correct? Or should I be using the server address?

If that's correct, then yes, that short response is all I got from the traceroute. Although I suspect I might be doing something wrong, since I had the same brief response just now when I tried google.com, which I can access just fine on this computer (not gmail, but the search engine itself).

At any rate, if it's a network problem that's actually a (sort of) good thing, since I'm getting a new internet connection in a couple of weeks - paid for personally, not part of a broader network. Here's hoping that does the trick.
