RE: [Sheflug] Blue Yonder + Linux

[Alan Dawson <nospam [at] chesterfield.ac.uk>]

I'm using SuSE 6.2  and managed to get dhclient to pick up an IP address for
my ethernet card last night. As I have heard people say use dhcpcd rather
than "pump" i was wondering what issues there may be with dhclient that I am
unaware of.
 
Also I'm wondering how best to set up the /etc/rc.config, and configure the
start up stuff so that dhcp is done before IP masquerading and ip chains.  

At the moment I have set up in rc.config eth0 to have ip adress 0.0.0.0
subnet 0.0.0.0 and gw 0.0.0.0 and then run  dhclient eth0 manually.

Surely there is a better way though - any pointers?

Once installed, you'll need dhcpcd (dhclient didn't work properly - pump 
is reported to be dire) on the box that connects to the cable modem, then 
all I do is run:
	dhcpcd -dRrC eth1
and I'm connected :)

For firewall ... you need to allow UDP between source port 68 (ie, your 
machine, port 68) and dest port 67. The rest of the firewall is standard 
config as far as masquarading is concerned...
	ipchains -I forward -s <localnet> -d 0/0 -i eth0 -j MASQ
.or whatever rule you wish to use in the forward chain.

Note: eth0 is the interface for my internal network, eth1 is the card 
that connects to cable modem.
