Hello everyone,

i spent most of last night trying to
set up a JavaStation to boot Linux 
over the net (one of those cool-looking
diskless gadgets Sun produced. It was meant
to run JavaOS but never really hit the market).
The box needs to get 2 bootimages from the 
server: a first one that patches the boot
prom (the original refuses to boot Linux)
and a second one that actually has the kernel
and some root file system.
Now, i can set the path/filename of the first image
from within the bootptab file (and that part seems
to work fine). But after the inital loading of
the patched prom the box requests the real kernel
image, unfortunately without any path (i.e. with-
out a '/' in front of the filename). My
tftpd server responds to relative filenames with
'security violation'. I there any way to loosen
this paranoid behavior?
My current inetd.conf line follows:

# tftpd bootimage server
tftp dgram udp wait root /usr/sbin/tcpd in.tftpd -s /tftpboot/

any help would be apreciated

  Ralf
