In order to configure a dsl ethernet modem in my IBM Thinkpad G40 running Debian 3.1 under a 2.6 kernel, with the tg3 driver for my Broadcom network card, I ran pppoeconf and everything was fine. I then ran ifconfig ppp0 and it worked, I used poff and pon to confirm thant every time it got a different IP, but when I try to access internet (eg. ping) it simply doesn't work. With Windows there's no problem. What's wrong?!

I already tried to ping ip addresses but the output is always the same: host not found. I'm not blocked by a firewall because I just installed Debian.

The /sbin/route is as follows:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.32.1.29 * 255.255.255.255 UH 0 0 0 ppp0
192.168.0.0 * 255.255.255.0 U 0 0 0 eth0
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0


Thank you.

Emilio

hi,
is 10.32.1.29 the IP address of your DSL modem ???

regards

I have no idea, but it's absolutely not the same as the ips dynamically assigned in ifconfig, which start normally from 200 and so on.


help!!!

ok.
post the out put of
#ifconfig

regards

ok, here's the output of ifconfig after doing 'pon dsl-provider' :

hi,
sorry for late reply.......i was out for a day.
after connecting to the internet check running the following command.
#route add default gw <The IP address you get at the highlighted position>

regards

hi ruudra, thanks for your reply but it didnt change anything. I ran 'route add default gw 10.32.1.29' after running 'pon dsl-provider' and it say anything so I thought it was ok, but I tried 'ftp ftp.netbsd.org' and 'ping www.ibm.com', i also invented an ip address to try with, with no result. It keeps saying 'host unreachable' or 'unknown' or things like that. Got more ideas?

Emilio

hi,
look at the last line of /sbin/route.
Destination with Genmask value 0.0.0.0 i.e for any network in this world the default gateway should be 192.168.0.1 (eth0).
but the entry here should be
default 10.32.1.29 0.0.0.0 UG 0 0 0 ppp0

thats why is suggested the command
#route add default gw <the ip address just after the P-t-P entry in ppp0>

your machine is well connected to the internet, but its not geting the default gateway.

post the o/p of #/etc/resolv.conf
the entries here are for your DNS servers.
can you ping them ? (although this is not the issue as you even can't ping a IP address, which doesn't require the intervention of DNS)
Since you are using debian, so search a bit about addding the default gw to it.
me too also trying, will let you know if get success.

regards

Ruudra, I made some foolish mistake:
Suddenly, I don't know why (perhaps after doing 'route add 192.168.0.0 gw *') internet worked!!!
but I decided to reinstall Debian because X wasn't working.
And... I am in the same situation as earlier... shit!!!
here's the output of /sbin/route after doing 'pon dsl-provider' and 'route add default gw 10.32.1.29' :

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.32.1.29 * 255.255.255.255 UH 0 0 0 ppp0

default 10.32.1.29 0.0.0.0 UG 0 0 0 ppp0
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0


now here's the output of ifconfig:

eth0

now, the output of /etc/resolv.conf BEFORE i did the foolish reinstallation:

search
nameserver 192.168.0.1


and /etc/resolv.conf AFTER the reinstallation:

nameserver 200.75.51.132
nameserver 200.75.51.133
search


and finally, the output of the 'plog' command, which I discovered when I ran once more pppoeconf:

Jun 3 18:36:58 localhost pppd[22927]: Couldn't increase MRU to 1500

Thanks for everything...

Hi
I think the problem is here
inet addr:201.245.212.153 P-t-P:10.32.1.29 Mask:255.255.255.255
the pointtopoint(gateway) address 10.32.1.29 seems totally strange.
Could you check what gateway you are getting from windows?
by
ipconfig
or
by
network properties
Try pinging 10.32.1.29
it should work (before anything else (nameserver) can.

It's the same gw in windows. HELP ME, PLEAAASE!!!!



Emilio

Try pinging 10.32.1.29

Also...

...I notice you now have two default gateways. If the ping fails, try deleting the one with 192.168.0.1

hi zhangmaike,
one thing is bothering me. 10.0.0.0 are for private networks. Then how come his ISP has given him that id ???

regards

check the mask :
The net mask should not be 255.255.255.255.
I missed that at first, but this must be the problem.
If the net mask is 255.255.255.255, your computer is the only one in the network which is not possible(Thought ,I have a network with netmask as 255.255.255.252)
The network mask is how the system knows the logical network the system is on.
Tell me how can the mask be /32?
check that out and your system should work.
Robin

THANK YOU EVERYBODY!!!

I'm writing this from Debian. You were right all the time, Ruudra, thank you!!!! The two things I had to do were


route add default gw 10.32.1.29
route del default gw 192.168.0.1


I would never had done this without your help.
Thank you.
