Edubuntu dhcp/tftp issues

[Jan]

Hello everybody,

actually i'm trying to setup a terminal-server based on ubuntu to get
some igel thinclients to work via nx. unfortunately that doesn't seem to
be as easy as i exspected. 

there is another (master) dhcp-server in the network, which cannot be
deactivatred as it belongs to a complex backup and restore system also
based on linux (this time debian). So i tried to let the master dhcp
lease the ips to the clients and redirecting them via the next-server
and filename directives to the edubuntu 6.10 tftp-server. Well this
doesn't work and so i tried to get the pxelinux.0 file manually by

tftp edubuntuserver
get pxelinux.0

which only works if the command is executed locally on the server and
doesn't work when any other machine is used. Any Ideas? And I have to
apologize for my english...
