Try either<br><br>socket://ws50:9100 or socket://<a href="http://172.31.100.50:9100">172.31.100.50:9100</a> in the printer connection definition.<br><br>The correct lts.conf file depends upon which image is being booted. If it is the i386 image, then /var/lib/tftpboot/ltsp/i386/lts.conf is the correct file.<br>

Hello,
<br>
<br>
I have installed K12Linux on Centos 6.2 per K12Linux Server Install Guide.
<br>
Using EL6-based i686 chroot.
<br>
<br>
Have not been able to print to a client attached printer with cups.
<br>
I can print to a direct jet printer attached to the switch on the 1st nic card ( non client network-168.192.1. )
<br>
Thin clients are on the second nic (172.31.100. )
<br>
<br>
Cups notes unable to locate printer by either
<br>
ip address (172.31.100.50) ie. socket://<a href="http://172.31.100.50" target="_blank">172.31.100.50</a>
<br>
or by lts.conf setup of alias [ws50]
<br>
<br>
Currently the server has 5 located lts.conf files,
<br>
<br>
/opt/ltsp/i386/etc/lts.conf
<br>
/var/lib/tftpboot/ltsp/i386/lts.conf
<br>
/var/lib/tftpboot/ltsp/ppc/lts.conf
<br>
/var/lib/tftpboot/ltsp/ppc64/lts.conf
<br>
/var/lib/tftpboot/ltsp/x86_64/lts.conf
<br>
<br>
Which one is used by client boot process?
