Internet Problems

[evulish]

Ok, I've had nearly-full installed SuSE 7.1 (kernel 2.4.2-4GB ( i think)) and I got my DSL working on it early on. I've run into a problem, though. There are many sites I can't get to in linux (ie. linuxnewbie.org, about.com, www.dal.net, (http://www.dal.net,) and lots more) I do have ECN disabled and I don't think I have any firewalls installed (and if I do, none of them have been configured) All these webpages I can get to on windows. (Sad ehh, I can't delete windows because I need it to get to linuxnewbie)

Any suggestions, ideas?

Do you have your isp dns servers setup in /etc/resolv.conf?

[slapNUT]

Look in /etc/hosts.deny and see if there are any IP's you don't recognize. If so go to an IP lookup and see what they are. Don't know how LNO would get there but it's always a good idea to keep up with that list!

ping the host in question by domain name; i.e. [ping linuxnewbie.org]. you'll see by the response if the host name was resolved to an ip address. That's just a start, though

Nothing in hosts.deny (or hosts.* for that matter). My dns servers work right. My traceroute doesn't usually finish, it gets stuck at the same place every time.

I used to have the same problem. Are you using PPPoE DSL? (dynamic ip). Heres the solution. You need to enable NetFilter in your kernel (the ipchains replacement) and then implement TCPMSS target. After you use the new kernel, you need to do a iptables command everytime you connect to internet. The kernel tells you to do this:
iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
but they are WRONG.
you need to use -I and not -A (if you search online, there is some website on a server with the url of something.waterlou.something which is very helpful.
