My client network boots with PXE and loads the install kernel but the
install kernel fails when it tries to obtain a IP address.
In the server log file I see the DHCPDISCOVER and then the DHCPOFFER by
the server.
dhcpd: DHCPDISCOVER from 00:06:5b:5d:5e:ce via eth1
DHCPOFFER on 192.168.1.2 to 00:06:5b:5d:5e:ce via eth1
It seems like the systemimager installed kernel does not recognize the
DHCPOFFER from the server.
I tried to use dhcp to boot a regular Redhat client and it works fine.
The only difference I can see is the Regular RedHat 7.1 client uses dhcpcd
to contact the DHCP server and the systeminstaller kernel uses dhclient.
here is my dhcpd.conf file
deny unknown-clients;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option domain-name "";
option routers 192.168.1.1;
# Defined cluster nodes...
subnet 192.168.1.0 netmask 255.255.255.0 {
group {
#
# this is the regualr RH client (ie: has OS on it already)
#
host oscarnode20{
hardware ethernet 00:06:5b:5d:5e:cf;
fixed-address 192.168.1.20;
option routers 192.168.1.1;
option domain-name "brockwulf.ca";
}
host oscarnode2{
hardware ethernet 00:06:5b:5d:5e:ce;
fixed-address 192.168.1.2;
filename "pxelinux.0";
option routers 192.168.1.1;
option domain-name "brockwulf.ca";
}
}
}
When the installed kernel fails I can get to the console. Is there
anything I can check from there? I tried to run dhclient again with some
other switches and changes to the conf file but still nothing.
Any ideas, suggestions of things to try would be greatly appreciated. I
don't know what else I can do?
Thanks
