-----BEGIN PGP SIGNED MESSAGE----- Hash: RIPEMD160 Using dump locally to a tape, or other device is safe. Using rdump and enabling rsh on a remote machine to dump to a device on that machine can be unsafe due to rsh, not dump itself. If you need to dump to a remote device, you can use ssh to make it safer. You can also look into using Amanda, which can use Kerberos to make the remote dumps safer as well. Amanda can use tar as well. As far as Amanda is concerned, dump and tar are interchangeable. Also, unfortunately the port for Amanda in the ports collection does not have options for Kerberos. You will need to look at the configure options to Amanda, and extract the proper configure switches, and add them yourself to CONFIGURE_ARGS (of course, after adding MAKE_KERBEROS4=yes to your make.conf). As far as I know, Amanda only works with krb4, not krb5 yet. I could be wrong.
