Since I upgrade our cluster from the FC14 to the FC15 I have a bad problem with the tftpd server.
I have some thinstations booting over the network after the update the boot failed with the message "TFTP open timeout".
I use an "ip alias" (cluster adress) for the tftp server (next-server in the dhcp), when I use the real ip I have no problem.
I found some information about a "Service Guard environment" and an option to enable it:
"This option is required for some tftp clients. These clients reject the tftp reply received from a
different IP address than the one requested when the server’s interface is configured with
an alias IP address."
I do not see an option like that in the tftpd server of the FC15.
