Hi Linux Dudes,
I have a fedora (FC3) box that I am setting up to run MythTV.
All was working fine with my current ADSL router (Origo 8400) - My win XP pc could talk to the internet, the fodora box could talk to the internet and the two boxes could talk to each other (Samba and HTTP (apache on the FC3 box)
I got a new router (SafeCom) that has wireless. I have sucessfully set up the router for wired and wireless on my XP pc but the FC3 box wont play along.
The FC3 box gets it IP etc through DHCP OK. I can ping internally (the router and my XP pc) and also sites on the internet (i.e. google.com).
When I try to access a webpage in Firefox (or Lynx) it just sits there... The DNS lookup seems to work ok because firefox shows "Looking up somesite.com" then "Connecting to somesite.com" but no actual HTTP traffic is transferred.
Interestingly, wget seems to be able to grab the front page from google, yahoo etc with no problems.
My initial thoughts were that it might have been something to do with having set up Fedora Linux with a 10.0.0.5 IP addr allocated by the my old router (origo) but now its being allocated a 192.168.1.x ip address by my new router.
With that in mind, I set up my new router to allocate 10.0.0.x IP via DHCP. I then used KDE network settings dialogue window to deactivate and re-activate the eth0 interface thus getting re-DHCPed.
Still no luck with the old IP address (10.0.0.5). Looking at the o/p from ifconfig I could see that the broadcast address was different:
OLD:
eth0 Link encap:Ethernet HWaddr 00:11
8:3D:5F:1D

I used ifconfig to force the bcast to the old value (255.255.255.255) but (surprise surprise) that didn't work either.
Just out on interest, I whacked in a Knoppix (3.7) CD that I have and rebooted. When Knoppix came up I was able to use Konqueror to browse the net etc. This proves to me that the issue is not with the router/linux combination but with the FC3 settings.
In case you can't tell, I am not exactly a linux expert (I'm not too bad though
) so any pointers or ideas on how to debug this problem would be greatly appreciated!! Maybe there is some file in which network settings were hard-coded at install time?? or a log to check that might give useful information?
Thanks in advance,
james
