----------- ------ ----------- -------
P60 does nothing but firewalling and gatewaying and vbox. (Very
small HD)
P500 does DNS, YPserver, Samba, mail etc. All others are just clients (win and SuSE)
Now there are two problems: 1. I can see (ping, telnet etc) P500 from P60 and from all other PC's. I can also get to P60 from P500. But to all others P60 is invisible and vice versa. 2. I cannot get ypclient to work on P60 (domain not bound), but it does work on other Linux machines connected to the 100mbps hub.
IIRC, you need to have ip forwarding enabled on the P500.
And a question: Do I have to use a different 3rd part of the ip-address (eg .2.5 vs .1.5) when using 2 hubs?
No, you are just connecting two subnets with the P500 acting as both a server and router.
I've tried the searching the howto's and other docs, but to no avail. Can anybody point me in the right direction? I feel it would be a waste of money to go out and get a switch hub, altough timewise... :-)
Have a look at http://www.linuxdoc.org/HOWTO/mini/IP-Subnetworking.html Pay careful attention to section 7 on routing. Your routing will be very similiar. Other sites that might be of interest. http://www.linuxrouter.org/ http://lrp.c0wz.com/ I agree that you don't need a switch as it probably wouldn't help unless it was one with a built in router.
