Dear Sun Managers,
I received several answers to my original question which was:
:> I use an SS10 running Solaris 2.3. This machine is on a large
:> network where all other machines run SunOS 4.1.3 (including the
:> servers).
:>
:> Here is the situation :
:>
:> The tape streamers are physically mounted on one of the servers
:> on our network. When I want to take a back up of my Solaris machine
:> I have to run "ufsdump" on the machine as root. In addition to that
:> I have to place a ".rhosts" file on "/" on the server to allow
:> root access for the Solaris machine. This is what I want to
:> avoid. That is, I don't want to have to use the ".rhosts" file
:> on the server.
:>
:> Can anyone suggest an alternative solution (if any) ?
:>
:> Furthermore, is it possible, on Solaris, to take back-ups as
:> an ordinary user and not as root ?
The people who replied are :
Markus Storm <storm@napier.sol.math.uni-paderborn.de>
Richard Davis <rad@getech.leeds.ac.uk>
Bruce L. Harrell <bharrell@digit.com>
Nick Murray <nmurray@csd.abdn.ac.uk>
Nico Garcia <raoul@MIT.EDU>
Gyula Szokoly <szgyula@skysrv.Pha.Jhu.EDU>
The solution to my problem was simpler than I had thought. An account
on the server is needed (eg. ``backup@the_server'') belonging to the
group "sys". Having this account available the "ufsdump" command is
used with the form:
... backup@the_server:/dev/rmt/0mn
This account, however, does indeed need a .rhosts file containing root
for my Solaris machine. However if security is compromised for this
account the situation will not be as bad as if the root account is
compromised.
Furthermore, people suggested the use of special software for taking
backups, such as :
Legato's Networker (v. 4.x)
Amanda (this one available from ftp.cs.umd.edu:/pub/amanda)
Thanks to all those who responded.
Regards,
Dimitris.
