Net connection worked until....

[11thistle]

... I tried to set up diald.

I had a network of 4 Win 9x boxes using a Mandrake 7 box as an internet gateway. I would connect using kppp on the mandrake box and then use any of the Win boxes for net access.

After an 8 hour session of messing with .conf files as per the howto we appeared to be close but had to call it a day.

I then rebooted the Mandrake box the next day.

I now have a situation where kppp dials and connects to the ISP but I can not establish any connection to the ISP from the Mandrake box let alone the Win boxes, (ie: can't ping any net address, can't use lynx, netscape etc).

I have returned all the /etc/*.conf files to their former settings since I backed up all of them (including rc.d/rc.local), but I am still stuck.

Basically the system behaves exactly the same as if I had not dialled the ISP if I ping, use lynx etc.

Can anybody help?

thanks

Can you ping IP addresses? i.e. 208.130.45.5 or something like that. Do you have valid working DNS server IPs listed in /etc/resolv.conf?
That's all I can think of. :)

Thanks Arvoreen,

No, I can't ping any internet address and there is no attempt to do so as far my modem lights indicate. Also, the connection speed graph with kppp indicates no activity at all after the initial connection to my ISP.

Resolv.conf is as it was when the system worked.

I also suspected a DNS problem but everything I know how to check appears ok.

All entries /var/log/whatever are clear of any errors.

The system behaves as if the ppp connection is somehow 'disconnected' from any network commands / applications, almost like a critical link has been lost somwhere.

Any more ideas?

Do you need to use proxy servers?

[11thistle]

No, I don't need to use proxy servers.

I discovered that If I do /sbin/ifup ppp0 the dailout and win9x connection sharing DOES work, so the problem may be with kppp.

I have looked at kppp settings and found nothing there has changed since kppp did work, so I don't know where top go from here.

Possibly unrelated is that on bootup, the linux box hangs for about 2 minutes on 'amd' and then boots normally.


Any other ideas?

Thanks

hey all,

i'm experiencing a similar problem:

i finally got ltmodem working on my winmodem, and the first thing i did with it was upgrade from debian 2.2r6 (tater) to 3.0 (woody).

now there are three new modules loaded on boot-up: afsockt, diald, and tap0. i can dial-up just like before with wvdial and connect with pppd, but every program that should use ppp0 gets routed to tap0 instead. problem is tap0 *doen't*do*a*godd@mned*thing*!

i know the problem lies somewhere in diald, pppd, or modules.conf. i'm just not sure yet if i need diald, afsockt, and tap0. even if i don't, i don't know how to turn them off.

anyhelp?

pieces,

Do you have /etc/sysconfig/network-scripts/ifcfg-ppp0 or similiar?

If you do, then see if it contains

onboot="no/yes"

and make sure it is set to 'yes".
