I figured it out.
If (in the configuration-dialogue for a system) you enter a "Gateway" in
"Networking (Global)" it is written to the dhcpd configuration file, as
an option for that specific host (together with the subnet-mask, from
the interface-specific, non-global "Networking" configuration.
However, the nameservers you enter there and the search-path are not
written into the dhcp configuration. This is actually opposite to what
I want.
Because, on the next reboot, the /etc/resolv.conf that is created by
the postinstall cheetah-script is overwritten by the value of the
"nameserver" line that I have to specify in the dhcp-template or else
the installer would stop and ask for one....
Is there some way to control what goes into the dhcp-configuration?
# group for Cobbler DHCP tag: default
group {
host generic1 {
hardware ethernet 00:0c:29:a1:f5:b6;
option host-name "ubuntu-test.espace.everyware.ch";
filename "/pxelinux.0";
next-server 10.38.111.19;
}
host generic2 {
hardware ethernet 00:0c:29:a1:f5:ac;
fixed-address 192.168.63.251;
option host-name "ubuntu-test.espace.everyware.ch";
option subnet-mask 255.255.255.128;
filename "/pxelinux.0";
next-server 10.38.111.19;
}
}
generic1 is actually eth1 and generic2 is eth0.
The first host is generated from data from the "Network (Global)" tab,
the second host ist generated from the interface-specific data from
the "Networking" tab.
I entered a MAC address for generic2 because the late_preseed script
insisted on the existance of a MAC-address (it would write an empty
hw-address line in the /etc/network/interfaces file otherwise).
I wouldn't need generic2 to even show-up in the dhcp-configuration, but
I can live with that at the moment.
Lastly, it seems static routes are not transferred.
I've entered a static loop in the form
net.work.ip.addr/subnet:gateway
But it did not show up.
Sorry for the long mail.
Regards,
Rainer
