I'm not having very good luck explaining... and of course PCE was
supposed to be PXE below...
As per Lewis' post on Centos + USB earlier?
Make sure
host 192.168.0.100
returns pc100.foo.bar.com
host pc100.foo.bar.com
returns 192.168.0.100
Mine does not have lookup (although I though using an IP address in CUPS
might still work. I can ping ws099 and get lookup:
PING ws099.ltsp (192.168.0.99) 56(84) bytes of data.
64 bytes from ws099.ltsp (192.168.0.99): icmp_seq=1 ttl=64 time=0.111 ms
However I do not get lookup either way with host:
host ws099
Host ws099 not found: 3(NXDOMAIN)
host 192.168.0.99
Host 99.0.168.192.in-addr.arpa not found: 3(NXDOMAIN)
Nmap shows port 9100 open:
Starting Nmap 4.20 ( http://insecure.org ) at 2008-06-12 23:16 CDT
Interesting ports on ws099.ltsp (192.168.0.99):
Not shown: 1695 closed ports
PORT STATE SERVICE
6000/tcp open X11
9100/tcp open jetdirect
Do I have something wrong with DHCP?
thx,
