Any one here using the Red Hat 6.x Amanda RPMs? I have what must be a FAQ
but I cannot find any answers in the docs and on-line searches.
I have two RH 6.x machines, remotehost and backuphost, and Amanda
2.4.1p1. I installed Amanda according to the docs with 'operator' as the
backup user. I created remotehost:/root/.amandahosts and
remotehost:/root/.hosts like this:
backuphost.ipat.com operator
I chmod'd both to 600 and chown'd to operator:disk. I've also tried
creating a user amanda.
(From experimentation) I have some permission issues on the holding disk
and tape device but no sweat; my problem is that root cannot logon from
backuphost to remotehost to backup remotehost. I know this not only from
the below messages but also the debug file on remotehost (i.e., amandad
runs fine on remotehost but cannot authenticate root@backuphost).
Now I'm wondering a few things:
No matter what login I use on backuphost, I am seen as root by
remotehost. Why is that? Is it because amacheck is SUID root.root (that's
how it was installed)?
How do I avoid this problem? I don't really want to give root access to
anything. I'm using amanda under the assumption that it is more secure
than, say, cobbling something together using rsh, .rhosts, dd, and tar.
BTW, why when I change the dumpuser to, say, amanda, does amcheck still
connect as operator?
Should operator have a homedirectory (apart from /root)? When I enable
rlogin on remotehost, I cannot rlogin, even with the .rhosts. I guess that
means that operator and root are equivalents to RH's security
mechanisms? I even uncommented the securetty line in /etc/pam.d/login but
that did not help.
THANKS in advance, this is driving me nuts.
