On itsdsv3 I have a dummy user set up that has write permission to the tape drive device. In this dummy user's home dir I have a .rhost file with entries of the sort: otherhost1.enc.edu root ...so root on otherhost1 can run dump u.... dummy_user@itsdsv3:/dev/nrst0 ... I have these dumps being invoked from a script. The script does this: 1. uses mt to rewind remote tape 2. uses mt to possibly skip forward x number of file marks 3. invokes dump several times to backup various local file systems Until recently, it worked fine, every time. Lately, however, I've been getting a "connection refused" error with step 2 or with the first dump invocation in step 3. If the latter, then the first partition dump is aborted but _all_other_ dumps complete without error!!! I'm a bit puzzled... Thanks for the reply. --- ------------------------------------------------------------------------- Charles N.
