Re: [expert] Internet connection broken
The other day i was happy to be moved from one @home backbone to another, much
faster one. As a result, my ip changed. Happily, none of my scripts (firewall,
etc) are statically set up ip-wise, and so everything adjusted perfectly. Of
course i'm using dhcp to obtain my ip, and that kept working too.
If DHCP was working before @home changed ips on you, then it would work after
also. Its functionality is absolutely not dependant on what ip it gets. It is
therefore a given that whatever you changed in the configuration is the root of
your problem (not that it's your fault, neccessarily, who knows, maybe some
config utility didn't work properly). Go back and check everything over with a
fine-tooth comb. And while you're at it, ask yourself why you had to change so
much due to simple ip-change (which is itself automatic).
In case it helps, i'll give you the shell code that grabs my current ip,
whatever it is, and puts it in a variable which i can then reference throughout
the script:
eth0ip=`/sbin/ifconfig eth0 | awk '/addr:(.+)[:space:]/{print $2}' | sed
's/addr://'`
There may well be a cleaner way of getting it. To be honest, i came up with
that code quite awhile ago, and it was a real struggle - so there almost
certainly is a cleaner, simpler way of getting it, but i just haven't had time
to do it :-)
By the way, doing ifconfig shows that your network card is not up, right? If
it doesn't hang on the dhcp request, then that shows that the card is not being
brought up properly - but it was before, right? So it's supported in your
kernel, and the only difference between then and now is that you fiddled your
configuation. Fiddle it back :-)
I hope that helps and i hope you sort it out :-)

I don't know why this would be. I've checked my settings in Windows, and it
appears as if everything is the same in both systems.
Other notes:

NIC to be properly configured
HardDrak shows my card as it is, a Via-Rhine 10/100 PCI card.
I tried running DrakProfile and getting that to set up my card. It said
loading drivers for via-rhine card or something similar, then complained
that my network card is not properly set up.

This is a big pain in the butt. My system works great asides from this
annoying lack of connectivity. I'm not going to make many Linux converts if
I can't show them a system that works with the internet. I can also not read

Re: [expert] Internet connection broken, + dmesg output
The other day I was annoyed to find that ATT @Home cable had changed my IP address without my knowledge. I played around in Linuxconf and DrakProfile to change system settings to reflect that. Next time I booted up, my internet connection didn't work. Now whenever I try to make connections to remote sites, I get unknown host. You are complaining about a static address issue, yet below, you say you are using DHCP (DYNAMIC Host Configuration Protocol); which is it...? I'm pretty sure it's static. But I'm also pretty sure that my IP address has indeed changed. Is it possible for static IPs to do that? This is the first time it's changed ever (stayed the same for over a year, since we got cable installed). But I always did need to type DHCPCD -I C428830-A -h home. com go get the network running when I logged in. Then I put it in some startup script so I didn't need to keep typing it. DHCP leases an IP address; sounds like you've been getting the same IP address every time... just lucky I guess. Ok, here's what I've *heard*: My cable provider does provide static IPs. However, it _says_ they are dynamic to discourage people from running servers. How do people who don't need DHCP connect to the internet from Linux, what program/script do they use then? Here's what bootup tells me: network: Setting network parameters: succeeded ifup: SIOCADDRT: Network is unreachable network: Bringing up interface lo: succeeded ifup: Delaying eth0 initialization. network: Bringing up interface eth0: failed Have you checked your NETMASK?

Re: [expert] Internet connection broken
I would say... open case, move sound card and network card to different PCI slots, close case and reboot, go into BOIS and disable P_N_P aware OS, boot into LINUX, , As root, run linuxconfig, from a console, and set up hardware and networking from there. then see what's up... maybe you have not set it all the way up again. - Original Message - From: Pierre Fortin [EMAIL PROTECTED] To: [EMAIL PROTECTED]; Mandrake Expert [EMAIL PROTECTED] Sent: Saturday, May 05, 2001 11:28 PM Subject: Re: [expert] Internet connection broken [EMAIL PROTECTED] wrote: Mandrake folk: duplicate eth entries... though the core issue appears to be IRQ conflict.

Re: [expert] Internet connection broken
No, they're not DNS problems. Using actual IP addresses gives me network unreachable. Dan ICQ 4689648 Are you running a firewall that is using your old IP address? Have you tried connecting direct to an IP instead of a URL (dns problems?)
