Hi Everyone,
I just "updated" my cobbler setup (yum -y update) and I have a bizarre
problem with a previously-working setup. It seems that now the network does
not work properly. When I kickstart a machine, if I ping the (temporary)
DHCP address that the machine is allocated I get three distinct phases:
[ While initial boot ]
From 10.5.10.5 icmp_seq=90 Destination Host Unreachable
From 10.5.10.5 icmp_seq=91 Destination Host Unreachable
From 10.5.10.5 icmp_seq=92 Destination Host Unreachable
["Sending request for
IP Information"]
64 bytes from 10.5.10.23: icmp_seq=93 ttl=64 time=1383 ms
64 bytes from 10.5.10.23: icmp_seq=94 ttl=64 time=383 ms
[ 2 or 3 pings later, when it attempts to download stage2.img - back
to Destination Host unreachable just packet loss ]
On the cobbler server, I get what seems to be a normal output:
Dec 23 18:43:33 gcisvlin-cobbler dhcpd: DHCPDISCOVER from 00:50:56:ac:5d:50

Has anyone seen this before? Any pointers? I can't see any obvious error
from the kickstart output, but even in tty3 it flashes past pretty fast.
Unfortunately, it dies before I get to a shell so I can't really debug
further, as it can't download stage2.img.
If it helps, both cobbler and client are VMWare ESX guests, and the cobbler
server has been used to kickstart a large number of other guests before! I
updated VMWare tools (on the cobbler server) during the upgrade, not sure if
that might be relevant.
Many thanks,
Alex
