UDP Checksum error

Mike O'Toole_1 — Wed, 12 Nov 2003 12:00:30 GMT

Hi All,

I am in the process of setting up LTSP for use in my network.

I have installed a R.H Linux 9.0 server..and installed and configured LTSP, as well as created the bootdisks for the clients.

When I boot up my client, everything seems to work ok...it gets assigned an IP address by the linux DHCP server, and starts pulling the Linux image down...but after awhile it errors out with the following message:

UDP Checksum error

Has anyone seen this before??

No exact match though.

Networking issues are likey to cause this.

Cables, routers, card drivers....

This is usualy hard to track, you/we need more information what about

# tcpdump

then start a client image download to see if we can more out of this ?
