Whether you are using Linux on the desktop or as a server, it's still good that you're using Linux. Linux related questions go here.

internet browsing spotty with my new ubuntu install

Post by Burrito »

something funky is happening when I try to browse online with my new ubuntu install. some of the pages load, others do not (devnetwork being one that doesn't :( ). When I try to ping an address, it resolves instantly so I know it's not a dns issue, but some of the address do not respond to my ping while others respond no problem.

I have 3 windows machines all on the same network and I can hit any of the sites that don't work on my ubuntu box just fine from windows. I'm assuming this has to be a network issue. I was set up for DHCP, but thought I might need a static so I changed to a static, but the problem still persists.

any ideas?

As for the ping issue, some servers deny ping requests for securty reasons so that didn't surprise me ;) Try it in windows too or just try telnetting to the server on port 80 if you're expecting a website ;)

What web browser are you using to browse with?

I had a problem like that a while back and the culprit ended up being the router. I was an old SMC router and I never figured out what the problem was -- but guessed it was the router and the Linux box arguing over something (most routers being Linux boxes). The new D-Link has been flawless. But that is not really a solution ...

root@tacostand:~# telnet forums.devnetwork.net 80
Trying 63.247.70.254...
Connected to forums.devnetwork.net.
Escape character is '^]'.

I had the exact same problem the other day using ubuntu... however the problem was resolved by rebooting the router (wrt54g)... i used ethereal to take a look at what was happening, but saw nothing out of the ordinary, dns worked fine, http get 1.1 was sent, but i never got anything in return, pinging, telnetting all worked fine. It was not a pure network problem as i was able to ssh to my internal webserver without a problem.. Had my brother reboot the router (i'm lazy) and the problem went away...

I'll give that a go tonight when I get home and report what I find out here.

Be sure your gateway is set to your router ip address in ubuntu.

indeed it is. if it weren't I don't think i'd get any of them to work, but as I said above, some seem to work, some do not.

I've had connections work with a bad gateway before, and the problem was similar to yours, that is why I mentioned it.

well I rebooted my switch and my modem/router and it still didn't work. I then noticed that FF was dying while it was trying to load google-analytics from this site which reminded me of an issue that you were having d11 (if memory serves me correctly). So I disabled JS and whola, it let me right through.

I"m actually on my ubuntu machine now. I must say though, I'm not super happy about having to disable JS...

ok, that wasn't my problem (I jumped the gun). some sites are still not working (in fact the majority are not). this smells of something network related, but I have no idea what or where to go from here.

I can't log into any of the IM networks on GAIM either, yet everything else network related seems to be just fine (just got a bunch of auto-updates).

I'm totally stumped.

this happened to me a couple weeks ago.. I ended up calling up D-link and they recommended I upgrade my firmware in my router which worked beautifully. For some odd reason I could only access certain pages as well, and this problem just happened out of the blue. Was really weird..

my little 10/100 switch is a netgear, but I don't have any problems with my windows machines? Perhaps arborint is right in that my ubuntu box is having a bitter disagreement with my little netgear thingy....

thing is, I would have no idea how I would upgrade the firmware on my netgear thing or if it's even possible.
