Proxy ISDN & autodial-up problems

Post by root » Sat, 20 Mar 1999 04:00:00



Hello I'm  a newbie in networking

I've a Linux box I've configured to act as proxy server for my LAN, i
use a ISDN link with dynamic IP.

The problem is that kernel continue to connect my provider and hang-up
after 60 sec.

I've turned off SAMBA and the eth0 device to prevent LAN interaction.

It seems to be a routing problem, but i don't know how redhat manage
such options

Technical Details :

RH 5.2
Kernel 2.2.2
Packages and scripts from http://sites.inka.de/picard/rh52_isdn.html
ISDN driver hisax teles 16.3
I use ippp0 as default gateway

Lotta THANKS!!!

Proxy ISDN & autodial-up problems

Hi,

    Hello I'm  a newbie in networking
    I've a Linux box I've configured to act as proxy server for my LAN, i
use a ISDN link with dynamic IP.

    The problem is that kernel continue to connect my provider and hang-up
after 60 sec.

    I've turned off SAMBA and the eth0 device to prevent LAN interaction.

    It seems to be a routing problem, but i don't know how redhat manage
such options

    Technical Details :

    RH 5.2
    Kernel 2.2.2
    Packages and scripts from http://sites.inka.de/picard/rh52_isdn.html
    ISDN driver hisax teles 16.3
    I use ippp0 as default gateway

    I'm using SuSE with same situation,  but there shouldn't be much
difference.
When you get connected /etc/ppp/ip-up is called with these
parameters:

    INTERFACE=$1
    DEVICE=$2
    LOCALIP=$4
    REMOTEIP=$5

    so you can setup your route:

    case `basename $0` in

    ip-up)

        /sbin/route add default gw $REMOTEIP dev $INTERFACE

    ;;

    ip-down)

        /sbin/ifconfig $INTERFACE down
        sleep 1
        /sbin/ifconfig $INTERFACE your.gw.ip pointopoint fake.provider.ip

    ;;

    ip-down is a symlink to ip-up

s. also in /doc/packages/i4l/README.IPPP

Hope this helps

 
 
 

1. ISDN & (unwanted) autodialing

I have linuxserver with SuSE 6.1 and an AVM-B1 isdn-card.

The /sbin/init.d/i4l_hardware and /sbin/init.d/i4l is started and the
default gateway is ippp0.
Each time I start my linuxserver, it want's to dial in (but it doesn't,
because it is in "dialmode off").

The error message is: "server1 kernel: isdn_net: ippp0: dial rejected:
interface not in dialmode `auto', signalling dst_link_failure"

When I delete the default routing, this error message occurred:
"server1 named[270]: ns_forw: sendto([128.8.10.90].53): Network is
unreachable"

I think, the BIND DNS wants to check some other nameservers.
How can I solve this problem (I need another way to configure the
isdn-network or another configuration for
my DNS)

thanx
