Re: [K12OSN]Centos+USB+local printer... and sharing it



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,
Scott S.

Here's the current stage... the dhcpd.conf file is working, it is assigning it an IP (and it is PCE boot)

    host ws099 {
    hardware ethernet 00:30:18:a6:97:a9;
    fixed-address 192.168.0.99;
    filename      "/lts/pxe/pxelinux.0";
    }

In lts.conf I have the terminal stated like this:

[00:30:18:a6:97:a9]
PRINTER_0_DEVICE        =/dev/usb/lp0
PRINTER_0_TYPE          = U
MODULE_01          = usblp

I'm pretty sure you don't need to specify MODULE_01 if you're using LTSP 4.2 (included in K12LTSP 5.0EL). I don't think it hurts anything, but you might want to take it out and see what happens. Everything else looks good.

In CUPS I added it like this, choosing HP and Laserjet 1200:

socket://192.168.0.99:9100

CUPS shows it as started, and it looks all happy:

Jun 12 00:00:11 ws099 lp_server: Started with: -n 9100 -w -d /dev/usb/lp0
Jun 12 00:00:11 ws099 last message repeated 8 times

Jun 12 00:12:38 ws099 lp_server: Started with: -n 9100 -w -d /dev/usb/lp0

CUPS gives an error of:
"/usr/lib/cups/backend/socket failed"

and the printer goes into:
Printer State: stopped, accepting jobs, published.

While it is in this stopped state, lpstat -l -a shows this:
lpstat -l -a
HP accepting requests since Thu 12 Jun 2008 12:13:54 AM CDT

I'm using local printers in K12LTSP 5.0EL and my configuration is the same as yours except that I use etherboot instead of PXE, and I assigned my printer using the hostname (which I have a DNS record for) instead of IP address. But the way you're doing it looks like it should work.
