Outgoing internet problem (but incoming works fine)

motie · n00b Joined: 16 Nov 2003 Posts: 30

I have one Gentoo machine that provides Bugzilla and SSH logins to external, off-site users. Bugzilla and SSH work fine. But I cannot get OUT from the machine via rsync (for portage updates) or web browsing with the links browser. But ping works.

1. Bad: emerge sync times out.

2. Bad: links (as in "links google.com") gets stuck at "Making connection".

Good: The machine still serves up Bugzilla to users over the internet just fine on port 80.

Good: I can SSH to the machine remotely.

Good: I can ping e.g. google.com just fine.

I haven't upgraded this machine in about a year and it's long past time for me to do so. But I can't get onto the internet from the machine via rsync or HTTP. Very strange. I have no idea what is wrong.

Note: I don't have physical access to the machine at the moment. All my problem reports in this post are based upon my remote login via SSH. However, I used to do all my emerge Gentoo upgrades via SSH so this did used to work.

Any ideas would be appreciated!

Hi.

How do you connect to the Internet? Is there any router/firewall in the middle?
if links doesn't work, I assume wget doesn't as well. Am I right? Do you use any proxy?

There's a router I use as a gateway.

I don't use a proxy.

wget does not work.

But ping works.

Here is my /etc/conf.d/net.

As weird as this sounds... It seems like that might be a network side problem and not your own side... I know of situations where natural disasters or other problems have dropped the link between some segments of the internet and others... In your case your traceroute is getting past your provider and out to level 3... Almost sounds like L3 is having some type of outage... It's a weird thought... But I've seen it happen before...

I wondered about that myself based upon the tracepath output. I'll have it looked into. But it sure is odd as this isn't the only machine using that gateway.

Here is my "netstat -atun" output. Does this explain why I can't browse the internet from this machine (port 80) or use emerge (rsync)?

Are you sure the router doesn't have a firewall? Could your router be blocking some traffic?
I assume you have an IPv4 internet connection. Do you have an IPv6 tunnel? If not, are you sure that your clients aren't having a problem with IPv6? I've heard of some web browsers, such as Firefox, having problems with IPv6 enabled hosts.

I tried another gateway and was able to get out onto the internet (my goal.) So it's apparently something with the original gateway, indeed.

Thanks to everyone who helped me.
