lan connection works but adsl doesn't, why?
hi,
i installed mandriva 2006 couple of days ago. i tried red hat and fedora which didnt work. my computer is dell inspiron 6000. The problem is i can specify the lan ip, dns, gateway everything and get it to work. i could access website normally in my lan. Now, i created new connection - adsl to be precise. after i do this i can neither access the local area network nor the internet. i have been trying every options since 3 days. i wish i had some linux using friend here, anybody please help me. i am a complete newbie in linux. i'm just sick of using windows and want some change....everything was going fine until adsl didnt work out. any response would be appreciated. thanks sabin |
can you give me this info:
ifconfig -a route and what type of adslmodem you are using, (router, via network , via usb) I think the problem can be a default route, but I hope you can give some more info about you network setup tlowk |
i dont use the modem..its a broadband, it works through network card thats realtek. and it was fine while using windows. i'll let u know the ipconfig in a while...

then you will probably need to use rp-pppoe
http://www.roaringpenguin.com/pppoe/ but you will need no address on the realtek network card then you need to can use the rp-pppoe (probably also included in mandriva) there are some startup scripts in the rp-pppoe package that can explain how to use it. It is not very hard to setup I remember. Tlowk |
here is ifconfig -a

did you run some config script?
you can also check the /var/log/messages file which can give some extra info |
what will that do?
i have no idea what to do |
grep pppd /var/log/messages | less
now you will get (if everything is the way I expect it to be) a log of the previous connections (up and down arrows , q to end) maybe you can find some message about what device is used for the pppoe which will be eth1 or eth2 from what I see, and what type of authentication (pap or chap) and is the username in the style (user@provider) |
i know i have to use eth0. coz its the network card. and i connect internet thru it. the problem is i can work with lan smoothly, no problem. its only whe n i setup lan and adsl both, i cant connect to lan and internet both. i know there should be some easier ways....

or am i just #$%ed up

You want to use your eth0 with an ipaddress and pppoe?
I've never done it but maybe you need to configure after setting up the pppoe connection the eth0 ip again ip a a 192.168.187.130/24 dev eth0 or ipconfig eth0 192.168.187.130 255.255.255.0 up do you have a reason the have the adsl 'modem' on the same nic as your network? |
of course!! i have broadcom 44X as eth0, this means i should be using pppoe and lan both from same NIC, dont i? but of course when i use pppoe i can't use lan or vice versa. and its not adsl modem, actually i dont know what it is. i have a this broadcom network card, which is the only way to access network recources, no modem no nothing. i get username and password from isp and use it which in windows xp works fine. this linux is driving me crazy!!!!!

How is the nic connected?
is it a pci card with a rj45 to you lan and a separate cable to you phoneline (or cable) another thing you can try in to see what it is doing in windows ipconfig /all route print maybe this way it is possible to find out what windows is doing with it, I hope that it explains what is going on since I don't see yet how your connection works another thing that can help is the program ethereal use the windows version and filter on 'pppoe || lcp' for your various network interfaces and see which one handles the connection. when connecting you will see stuff like PADI PADO PADR PADS and LCP packets |
I see you configure DHCP on your ppp0 which is not very common, since the ppp protocol has its own system to configure that info, I think that it is in the LCP packets.
