I've been testing dialup slip on Suns. While basic slip works, I've had trouble getting routing to work right. Here is the configuration: --------------------------------------------->>>> rest of the world | 128.52.10.1 host A 128.52.11.1 | | <==== via SLIP | 128.52.11.2 host B (dialup host) 128.52.12.2 | ---------------------------------------------- I'm running gated with "RIP yes" on host A. When host B dials up, it invokes, on host A: sliplogin 128.52.11.2 128.52.11.1 255.255.255.0 Then, on host B (directed to correct tty line): sliplogin 128.52.11.1 128.52.11.2 255.255.255.0 (BTW: Tip with slip support is core dumping on me. I've got the copy from the "slipware" distribution.) This starts up slip fine, allowing host A and B to talk to each other using 128.52.11 addresses. If I do the following on host B: route add 0 128.52.11.1 1 to setup a default route, host B can now talk to host A via the 128.52.10.1 address as well. However, host B cannot talk to the "rest of the world" because gated on host A isn't pushing the new slip route around. A couple of questions: 1) I'm using net 128.52.11 as a slip connection network, with only two hosts on it. Is this the right way to do it? I may have additional machines on 128.52.12, on the dialup end, by the way. 2) On host A a point-to-point route is installed, basically of the form that you'd get from "route add 128.52.11.2 128.52.11.1 1". Should this point-to-point route get broadcast from 128.52.10.1 to the "rest of the world". I'd think this should done by gated. 3) Gated by default only sends out RIP information if more than one interface is present. When I first boot host A, it only has the 128.52.10.1 interface. Thus, gated doesn't send routes out. When I add the slip0 interface to 128.52.11.1, does gated start to send out routes? Should I configure gated with a "RIP suppier" instead of a "RIP yes" entry in gated.conf? 4) The slip net (128.52.11) doesn't support broadcast. What should I do to allow the gated on host B to send routes (for example, the route to 128.52.12) to the gated on host A? It looked like gated supported something to do this, but I couldn't get it to work. Thanks for your help, -Dave
