Can only connect from WinXP

h2gofast · 09-02-2005, 02:15 PM

title sums it up.
I thought my router might have been puking on me. But now I don't know, I hooked my pc directly to the modem with no router in between.
Modem dishes out ip address dhcp style, ifconfig shows the right ip, but no internet.
Running debian sid, I just apt-get upgraded yesterday, but this started this morning.

I'm posting from WindowsXP, so I know the modem works and my connection is fine.

. Ip is gotten dhcp.
I can't ping anything

resolve.conf has the usual ip addys.
ping 66.102.7.99 yields host unreachable
ping 66.94.230.32 yields host unreachable

The router gets an ip from the modem.

It seems that the only way I'm allowed to access the internet is when winXP is connected directly to the internet. Call me Oswald but strangely, that's the case.

Whether I'm behind the router or connected straight to the modem the box can't get on the internet unless it's booted into XP.
I'm baffled, please help.

MyfFirst guess would be that you aren't getting the route setup correctly. Can you print the output from route and ifconfig -a.

Thanks.

Thanks in advance for your help. I'm baffled

1) looks like your eth0 isn't receiving an IP. Why that is, I have no idea. You might want to reconfigure that to accept DHCP.

2) Your broadcast on eth1 looks off a little, too. In reality, it should read: 24.145.159.255. your mask can be whatever, although, if you want to follow the IP conventions, it's off a little too. See, 24.145.159.194 looks like it should be a class A subnet and your subnet is a class C. That's a little too trivial anyway.

Check that stuff out and let us know. Those were just some observations that I had made.

h2gofast · 09-02-2005, 04:06 PM

eth0 shouldn't even be coming up. It's the mobo's onboard ethernet. eth1 is the linksys card which I use because windows doesn't seem to like the mobo's ethernet.
As for the other stuff I'll check.
thanks.

thanks for the input. I swapped routers and now it works.

If anyone can explain that I'd like to know.

Possibly the router was giving incorrect addresses. Not enough information here to say for sure. Glad you got it working.

hi im a linux newbie and i got d same problem =( on WinXp i dont have any problem connecting to internet. I dont use router. Im using debian sarge.

Well my pc has 2 lan cards installed but i think debian correctly identified them. Well d first time i configured it, it succesfully connects to d internet and i was able to surf but when i restarted my pc and tried to connect again, it just doesnt connect anymore. I tried "pon dsl-server" but still d same. I didnt change any settings when i restarted my pc. I tried reinstalling again debian but i got same result.

Is it that im using 2 lan cards? havent tried to removed it yet.
Pls help a noob at linux. T_T

jonlake · 09-03-2005, 09:23 AM

To make sure the kernel is recognizing the cards as being present, as root do
# lspci
also do
# ifconfig -a
# lsmod
If you can post the output of these we can get started helping you.

Tnx ^^. I will try later when i get home

Constipation · 09-04-2005, 03:39 AM

I wasnt able to try those commands jonlake coz i forgot to write down the commands. ^^ lol. Coz my pc is at home. and im at d office now. Well i removed d other lan card but d same result. When i run ADSL/PPPOE Config, it sometimes doesnt detect the DHCP something and sometimes it can succesfully detect DHCP settings with or without the other lan card. When i run plog, The message appears "Timeout waiting for PADO packet, Unable to complete PPPOE Discovery." Does it have something to do with my modem? Its wierd coz i was able to connect to the internet the first time i configured the ADSL/PPPOE Config...
