(K)PPP(D) Problem

Beginner

Wednesday, July 2nd 2003, 2:44pm

I have this problem.

KPPP works fine and connects using my AMR modem (I installed a special driver for it and it seems to work correctly). When I get connected to my ISP the only thing I am able to do is to ping the ISP server. I am not able to ping or connect to any other internet address (nor I am able to use any browser or Internet app).

What do you think may cause this? Do you think I have something not configured correctly? I am pretty new with Linux. I have been playing with it for about 1/2 year.

I tried everything in the Q&A section in the KPPP handbook. Nothing helps

Please help me if you know something. Thanks!!!

You may have incorrect IP addresses for your ISP's DNS servers. I would double check those first.

Try
ping 80.232.38.131

(that's www.kde.org)

if this works, its a DNS problem as erugger66 suggested.

if it doesn't work, it is very likely a routing problem (for example default route not set)
in this case post the output of
route -n
(while being connected)

In either case it is always a good idea to post which distribution you use when you've got a problem.

Thanx to both of you.

I thought that the DNS server may cause this but how the h*** (sorry :oops

could I found out the IP address of my ISP DNS server. Is this the IP address of my ISP provider (e.g. the IP of the computer that my PC connects to)? Or is this different IP? I don't remember to have set such thing under Windowz. I was also not able to find this info on my I-net card.

I will try the route -n and post the output here. Thank you anda_skoa!

I am using Peanut Linux with KDE3.1.0, XFree86 4.3, Kernel 2.4.20... most latest version. Small but cool distro.

Hi nothing helped for now. Here are some interesting outputs:

Peanut-Linux:~# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
212.50.0.210 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo

Peanut-Linux:~# ping www.yahoo.com
ping: unknown host www.yahoo.com

Peanut-Linux:~# ping 80.232.38.131
connect: Network is unreachable

If this can lead you to something... :? Thanx!!![/u]

The routing table is missing the default route.

I think the ppp daemon or kppp should set this.
See if you can find an option for that.

The default route should point to the other side of the PPP link.
I think it is listed in the output of ifconfig

I didn't find any option for this in KPPP.

Quoted

The default route should point to the other side of the PPP link.

Isn't this it:
212.50.0.210 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0

The first part of this line is the IP of my ISP (e.g. the other side of the PPP link).

Any other ideas. I really would like to use my Linux for Internet. Thanx again for the efforts!

In this case you could try to add the default route manually.

something like
#> route add default gw 212.50.0.210

But there is something wrog with the ppp configuration if this is not set automatically.

Unfortunately I don't have a ppp connection myself, so i cannot provide more detailed info.
