Subject: Re: dhcp client
Ok, I've build my dhclient. But I'm just running into more and more
problems, I hope you can help me out, but this might be getting more of a
dhcp problem then an owl problem now...
problem 1: dhclient seems to require a "/etc/dhclient-script", which was
missing (shouldn't a default version have been installed with the rpm ?).
My solution: I found the attached file on the internet and used that.
problem 2: dhclient seems to require a "/etc/dhclient.conf" file, which was
also missing.
My solution: I've constructed something from man-pages and googling for
information, also attached.
The system I'm building is going to have to ethernet cards installed:
- eth0: DHCP
- eth1: 192.168.0.16 netmask 255.255.255.0
So I edited /etc/sysconfig/network-scripts/ifcfg-eth0 and -eth1.
-- /etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=Ethernet
-- EOF
problem 3: when "ifup" gets run to get eth0 up, it tries to use "/sbin/pump"
instead of "/sbin/dhclient" for DHCP. (This must be an old script or
something !?)
My solution: I edited ifup, added a small part for "BOOTPROTO=dhclient"
which would do
-- /etc/sysconfig/network-scripts/ifup:
-- *SNIP* --
echo -n "Requesting DHCP information for $DEVICE..."
if ifconfig $DEVICE up && /sbin/dhclient -q $DEVICE ; then
echo " done."
else
echo " failed."
ifconfig $DEVICE down
exit 1
fi
-- *SNIP* --
problem 4: dhclient won't work. It gives "/sbin/dhclient-script:
configuration for eth0 not found." error messages and it just seems to keep
on DHCPDISCOVERing forever without accepting a DHCPOFFER.

Anyway, I hope somebody has the time and knowledge to help me out with all
this, thanks in advance!
Cheers,
