- If you still have the complete list of these then you know
- which files were hosed and need to be replaced.
- ...
- }that you can pirate a disk from, then you need to proceed as follows,
- }which requires only a tape drive.
- }
- } The *easy* way, and the one I suggest, is to boot from
- }tape (or whatever your installation media is) and select the
- }"systems management" option.
-
- If you are lucky and your site has a mop-load server then
- boot -f mop()
- boot #/mop (# is usually 3 or 6 I think)
- will boot from it (over the net) and you can then choose
- "systems management".
-
- } Now you have a couple of options. If you've got an existing
- }ULTRIX machine that is up and running, I suggest you get a copy of
- }"tar" from it. I don't *THINK* the standalone system has "tar".
- }(the standalone system is all a root filesystem in a RAM disk, and
- }has not got a lot of room to waste). The way to do that is to just
- }get onto a working machine, mount a tape, and use dd to copy the
- }executable to tape, then copy it back onto the system you're
- }trying to repair.
-
- Again, if you have a another machine up and running on the net,
- then you can goto that machine and add "hosed.machine.name root"
- to /.rhosts and then on your hosed machine:
-
- /bin/hostname hosed.machine.name
- /etc/ifconfig ln0 `/bin/hostname` up
- /bin/rsh ok.machine.name cat /bin/tar > /bin/tar
- /bin/chmod a+x /bin/tar
-
- and, voila, you have tar (other handy tools can be gotten the same way).
- Much faster than dinking around with tapes if you can do it. If you
- have a tape drive you can follow mjr's instructions (if not, you
- can use something like:
-
- cd /mnt/usr/users
- /bin/tar cf - . | rsh ok.machine.name "(cd /some/place; tar xpf -)"
-
- Every time I see a mangled disk, I am ever so thankful that:
-
- (a) most of our workstations are dataless
- (b) we have a mop-server machine
-
- Good Luck,
- John
