I'm using pxelinux, dhcpd (v2.0pl5), tftp, and kickstart to install
redhat 7.2 on IBM x330's.
Anaconda cannot get a dhcp address, mind you it gets one fine during the
pxeboot process, and gets one fine after the kickstart install fails and
i configure dhcp within anaconda and do a manual install.
I ran a sniffer and observed a problem with the dhcp transaction.
Normally, the transaction is as follows
Discovery (client)
Offer (server)
Request (client)
ACK (server)
all 4 packets have 1 transaction id.
the attempted transaction in question works as follows:
Discovery (client)
Discovery (client)
Offer (server)
Offer (server)
--and it fails... all 4 of these packets have a single transaction id as
well.
I'm not sure if its a problem with the client or the server. If it's the
client, Id guess theres a problem with my default config file for
pxelinux, and if it's the server i'd guess its a problem with my
dhcpd.conf. Any suggestions?
Here's my setup:
/tftpboot/initrd.img
/tftpboot/vmlinuz
/tftpboot/pxelinux.cfg/default
#/tftpboot/pxelinux.cfg/default
default linux
prompt 1
timeout 30
label linux
kernel /vmlinuz
append load_ramdisk=1 ramdisk_size=32768 initrd=/initrd.img
ksdevice=eth0 ks=nfs:/172.16.6.2/kickstart/ks/ksf.cfg
(it's one line in the file)
#/etc/dhcpd.conf
allow bootp;
default-lease-time 259200; #3 day lease
max-lease-time 691200; #8 day maximum lease

}
host pxeboot2 {

fixed-address 172.16.6.253;
}
}
#range
subnet 172.16.6.0 netmask 255.255.255.0 {
range dynamic-bootp 172.16.6.129 172.16.6.252;
}
my exports are fine. /kickstart/ks is exported to the correct network.
(the reason I have the seemingly redundant directories of /kickstart/ks
is so that I can have a seperate share with different permissions
(writable) called /kickstart/logs where I store mac-address labeled logs
of the kickstart install.
when i used the same kickstart file (which i wont include because thats
not the problem) and boot via a disk and use this dhcp server (without
the allow bootp, or the pxe boot group) the kickstart install works
fine.
Thanks for the help in advance.
