Hello all, In the network there is already a W2K server serving as DHCP server for the network. Then we want to implement LTSP, so we need to setup another DHCP server, right?

Can we then have 2 DHCP server in the same subnet, only serving pre-determine clients

Hi all, When we create a custom chain in iptables, should we specifically create a rule to 'jump back' to the previous chain? For example: iptables -A INPUT -j CUSTOMCHAIN iptables -A CUSTOMCHAIN rule1 iptables -A CUSTOMCHAIN rule2 Should we add: iptables -A CUSTOMCHAIN -j INPUT ? Or, it will automatically go back to CHAIN when there's no more rule? Thank you very much, -- Fajar

The first hurdle was that "portmap" didn't appear in the chkconfig list, it was installed with the initial packages but not added to chkconfig. Took me a while to figure this out. Adding and starting it up is no
