Well, it appears that this one downloads code (kernel?) and the screen
goes blank for about 15 seconds. I think it's trying to find its server
for tftp and nfs, because when the screen comes back a bunch of tftp and
nfs messages fly by.
nmap on my Sun tells me these ports are open on the HP server:
21/tcp open ftp
23/tcp open telnet
111/tcp open sunrpc
113/tcp open auth
135/tcp open loc-srv
512/tcp open exec
513/tcp open login
514/tcp open shell
820/tcp open unknown
838/tcp open unknown
842/tcp open unknown
846/tcp open unknown
851/tcp open unknown
854/tcp open unknown
6000/tcp open X11
6111/tcp open spc
6112/tcp open dtspc
7000/tcp open afs3-fileserver
Looking at a tcpdump of the boot process:
Get kernel with tftp, "handshake" on port 69, the transfer on high port.
Grab default.cfg from server via tftp.
Looks for a file named modules.ld or hostname.modules.ld, also tftp.
Then popupd, rgb.txt, hosts file, fonts.dir, fonts.alias.
Lots of packets for the rgb.txt and fonts files.
After that it starts an X11 session.
There's also some afs3-fileserver exchange.
After that, it's off arnd running.
I don't know if this helps much, because I obviously don't *really*
understand all that is happening here. I think Iused some pre-packaged
setup on the HP host, but it was a while back.
If you really do want to make it go, I can send you the tcpdump record
of the boot process and/or a tcpdump record of the boot process when
there are two hosts involved: one for the kernel download and second one
for the X session.
