Hi,
I'm trying to boot some bare metal over the network. I followed all the steps
in the tutorial:
https://fedorahosted.org/cobbler/wiki/HowToCobblerServer
When I run cobbler check it just tells me this:
[EMAIL PROTECTED] cobbler]# cobbler check
The following potential problems were detected:
#0: since iptables may be running, ensure 69, 80, 25150, and 25151 are unblocked
And I did make sure that these ports are open. I then set the bare metal bios to boot
from the LAN first, but I still get a "NO BOOT DISK FOUND ERROR...or something like
that".
Is there a way to simulate the request that boot client should be sending to
cobbler?
There are a couple things you can check - during your pxeboot phase do
you see a timeout or anything like that? I find it helpful to do a
tcpdump on the cobbler box to see if infact the pxe and dhcp packets are
making it from the host to the server.
You can also tail /var/log/messages (by default) or /var/log/dhcpd (if
you setup a syslogd rule for dhcpd) to see if there are requests getting
through to the server. One common mistake I make is that I forget to
add a subnet in my dhcp.template, and because of this my pxe requests
will fail (as dhcpd won't be configured to offer leases on that
subnet). This will usually show up in your log file.
