It would be helpful to know where it hangs. There are some issues i know of: - UDP source port for tftp has to be < 32768 (for broken indy prom) can be controlled via a /proc/sys/net var under linux. - linux 2.4 needs to set ip_no_pmtu_disc - DHCP replys must be carefully tweaked (sniff the replys with ethereal) The dhcp problem is very annoying... i tried setting the nfsroot etc. in the dhcp reply, but the dhcp reply is length-restricted, so if i did send the full nfs path, other options got dropped and the indy didn't react at all on the dhcp reply... dhcp has a field to set the maximum length of packets, but the indy does not use this in the request, so the reply is limited to the default packet size. I used ethereal to inspect the dhcp replys and strip off anything not absolutely needed... But then i decieded to boot the indy from disc, to get rid of supplying a long boot command each time... Would be very nice to have the indy net-booted though, as it then would be really quiet... Greetings, Erich
