[SunRescue] Diskless Workstations

[Sheldon T. Hall]

Excellent!

One last question ... how do I get the appropriate executable files from 
the CD-ROM into the various directories?  The IPX (server) is Sun4c and the 
LX (diskless client) is a Sun4m...

Thanks a ton.

 I net boot my sun3/80 from a solaris 7 machine. Essentially what you do is 
as follows.

remove the comment from the line in /etc/inetd.conf that contains a listing 
for tftp

Add a line to /etc/ethers that looks like the following, MAC address name
08:00:20:01:02:03   sun380

The mac address should display on boot. If not, use snoop to look for the 
address in the rarp broadcast packets.

Add a line to /etc/hosts with a name that corresponds to the new diskless 
machine. It should match the line in /etc/ethers

Start in.rarpd (/usr/sbin/in.rarpd -a)


Add a line to /etc/bootparams for the machinei
sun380   gateway=192.168.1.2 root=ultra:/opt/export/sun3/sun380/root 
swap=ultra:/opt/export/sun3/sun380/swap 
dump=ultra:/opt/export/sun3/sun380/dump

You need at least root, swap and dump. Those are paths to the files they 
will use. The swap file should be created with mkfile, the dumpfile is a 
copy of the swap file (I don't know what it does, but it works)

start bootparamd (/usr/sbin/in.bootparamd)

Add entries for NFS mounting the appropriate shares. You need to share 
root, swap and dump at least. My config looks like :
share -F nfs -o rw=sun380,root=sun380 -d "Sun3X root" 
/opt/export/sun3/sun380/root
share -F nfs -o rw=sun380,root=sun380 -d "Sun3X swap" 
/opt/export/sun3/sun380/swap
share -F nfs -o rw=sun380,root=sun380 -d "Sun3X swap" 
/opt/export/sun3/sun380/dump

restart nfs

Boot your machine and monitor the network with snoop. It should give you 
information about any errorsyou encounter. If you get stuck, feel free to 
call me at 299-4322 (I'm in Columbus as well)
