Need help with Internet connectivity issues

snatale1 · 03-29-2010, 05:58 PM

I noticed today my dropbox wouldn't connect, so I reinstalled, still nothing. Tried to reinstall from the repo, nothing. While doing this I noticed that apt cannot check repos, or synaptic. Browsers have no issue but it looks like the system itself does. same goes for Ubuntu update manager and software center. Any clues?

Check your apt configuration files (specifically sources.list), you also might want to verify you can resolve off the name servers listed in /etc/resolv.conf if both of those check out run rkhunter and chkrootkit.

If your sources.list turns out to be valid, then try going to: system > administration > software sources. From the drop down box next to "Download from", try choosing the main server instead of the USA server.

You might want to try flushing your iptables rules and seeing if you can connect while they're flushed also, I've seen people add rules that break some out going routes also.
