Routing Problems in SuSE8.0
I am having big problems setting up a small network under SuSE8.0 Everything was fine until I got my isdn connection working beside my DSL connection. Then as far as I can tell the routing tables went to hell. I would describe what I've done but I've fiddled so much that it's a mess, so I'm going to describe what I want to achieve and pray that someone can tell me what I should be doing and where I should be doing things. I've got two computer 'beast' and 'laptop'. Beast has two ethernet cards - one connected to the local lan and the other connected to my broadband connection (PPPoE). I want the local network setup on net 192.168.15.0. The ips are: beast 192.168.15.2 laptop 192.168.15.8 At the moment they can't see (ping) one another. The PPPoE connection works, almost regardless of what I do with the eth0 and eth1, even when I delete them! I want to setup so that beast and laptop so that they can see one another so I can mount NFS etc. and setup the beast as a gateway for laptop for the internet. This was all working a few days ago. For what it's worth the output of route (with the ppp0) connection is: Destination Gateway Genmask Flags Metric Ref Use Iface 61.48.57.254 * 255.255.255.255 UH 0 0 0 ppp0 192.168.15.0 * 255.255.255.0 U 0 0 0 eth0 loopback * 255.0.0.0 U 0 0 0 lo default 61.48.57.254 0.0.0.0 UG 0 0 0 ppp0 With the ppp0 connection closed the output of route is: Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.15.0 * 255.255.255.0 U 0 0 0 eth0 loopback * 255.0.0.0 U 0 0 0 lo As I say I've fiddled so much I've gone around in circles and am no longer clear on anything. Help much appreciated, Jethro -------------------------------------------------------

Help much appreciated,
Did you get the sysconfig update from YOU? It could seem like that is the one that bites you. -- Mads Martin Jørgensen, http://mmj.dk "Why make things difficult, when it is possible to make them cryptic and totally illogic, with just a little bit more effort?" -- A. P. J.

I have done one YOU update since I installed SuSE8.0 (sometime in the last 2 weeks). Can't remember if it stopped working after that. Anyway am doing another YOU update right now and will see if that improves anything. Jethro
BTW. How using YAST2 do you delete either an ISDN or a DSL connection. From my experience once you've set them up you can't delete them - you can only set them up 'incorrectly'. Jethro
This is what I have done so far... 1. Used YOU to update everything including several YAST modules. 2. Deleted both ethernet cards and set them up again. No joy. 3. Went out turned computer off. Came back turned it on. Nothing changed (good). 4. In frustration deleted both ethernet cards AGAIN in the beast. Re configured them both on the network 192.168.15.0. (.2 and .3 respectively) No joy I couldn't ping my laptop. But I could ping Windows 2000 running in VMWare which I hadn't been able to do before. 5. Swapped the cables for the lan and the dsl (ie changed which ethX each was plugged into). Hey presto I could now see the LAN. But I can't access the internet. Out of desperation I ping 192.168.99.99 (which I've found in KInternet's log file). The dsl connection springs to life and I can access the net. route gives the following output: 61.48.57.254 * 255.255.255.255 UH 0 0 0 ppp0 192.168.22.0 * 255.255.255.0 U 0 0 0 eth1 192.168.15.0 * 255.255.255.0 U 0 0 0 eth0 loopback * 255.0.0.0 U 0 0 0 lo default 61.48.57.254 0.0.0.0 UG 0 0 0 ppp0 I check and I can stil ping laptop on the LAN. Looks like progress. A little while later my dsl connection times out and once again there is no automatic connection unless I ping 192.168.99.99 Whilst I'm not connected the route command just gives me: beast:/home/jsc # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface And hangs there until I issue ctrl+Z. Is this normal? It seems to me that when the dsl connection comes down the routing table isn't being written properly. Anyone know what I should do? Jethro
