I downloaded DVD Stable 2 and booted from it.

I did "Install to Hard Drive."

After installation, I did the following to get the mouse to show up:
  yum -y --enablerepo=updates-testing update xorg-x11-drv-openchrome
  reboot

I followed the instructions in the "K12Linux Quick Start Guide."  The only
difference with my system is that I am using eth1 for my ltsp network.

I booted a client (one that has worked on K12LTSP 5EL).

The cliented loaded up through initrd.ltsp  Then, I got the following error:

  mount:: RPC: Authentication error; why = Failed (unspecified error)
  nfsmount: error mounting 172.31.100.254:/opt/ltsp/i386 on /sysroot as nfs:
Bad file descriptor

tail /var/log/messages showed:

  Jan 18 10:54:48 localhost mountd[2333]: Warning: Client IP address
'172.31.100.100' not found in host lookup
  Jan 18 10:54:48 localhost mountd[3345]: connect from 172.31.100.100 to
proc (1) in mountd: request from unauthorized host


I added the following to /etc/hosts:
  172.31.100.100  ws100

Rebooted the client; same error at the same place.  /var/log/messages now
does not contain the warning, just DHCPREQUESTs and ACKs.

I would appreciate someone's help on this.

Thanks,
Steve
