David, 


Is ICMP disabled? It would explain being able to receive an IP but unable to ping. 
Not sure. I'll investigate the topic this evening. 






$ telnet <printer ip> <printer port> 


is a way to test. HP network printers have telnet built in. 
When I try 192.168.1.6 (IP of printer) it hangs at "Trying 192.168.1.6..." 
When I try 192.168.1.9100 or 192.168.1.6:631 I get, "nodename nor servname provided, or not known". 






By the way, is 192.168.0.1 the IP of the server or the printer? It seems like a server address to me. 
It is the server... do I have something backwards? 

you need the ip address of the thin client , the best way is to make a static entry in the 
/et/ltsp/dhcp.conf for the mac address of the thin client 
then in the lts.conf (either /opt/ltsp/i386/etc/lts.conf or /var/lib/tftboot/) you need to create a mac address entry for the thin client specifying the printer port , either usb or lpt 

I would then advise creating an active shell in the thin client , 

sudo chroot /opt/ltsp/i386/ 
apt-get install openssh-server 
then run passwd and create a password 
then update you image 

once you have rebooted you should be able to ssh in to the thin client and run netstat -an | grep tcp and see the printer server listening on port 9100 

then try again. 

I hope this heklps as is acurate

You should be able to set a static IP address on the printer through telnet or the printer's menu. 






Your project is great. Good luck. 
Thanks Ben--while it's true that I am leading this charge, it really is a team effort--thanks to all those who have helped/are helping/will help pull this project out of technological mud holes!

Still no luck. While sitting in front of the Jaunty thin client server (virtually) I can't ping the printer. However, it appears the printer is getting an ip from the server. This doesn't make sense. 

Any ideas? I really need to get this printer working. 

Thanks, 
David

Hi All, 

The server seems to be working great, booting 18 thin clients easily. The thin clients run Firefox 3.5 and CmapTools as local apps. iTALC and Sabayon working well. Lots of joy here :) 

The issue I'm encountering is I can't get the printers to print on the LAN. I've googled, explored, googled and explored more. 

The cupsd.conf setting are shown below. In the printing control panel I've set the Device URI to socket://localhost:631 (and tried typing in 192.168.0.1 in place of localhost, and lpd in place of socket). It appears that the printer is working with the message: "processing - printer is now on-line" nonetheless, nothing prints. Any thoughts? 

Thanks, 
David
