        Hello,
                I am doing an rdump and it fails. Below is the
        output from my dump. Does anyone have any ideas?
        
        Thanks in advance. I`ll post a summary ASAP.

          DUMP: Date of this level 0 dump: Wed Jan 6 08:50:01 1993
          DUMP: Date of last level 0 dump: the epoch
          DUMP: Dumping /dev/rsd0a (/) to /dev/nrst8 on host zeus
          DUMP: mapping (Pass I) [regular files]
          DUMP: mapping (Pass II) [directories]
          DUMP: estimated 8232 blocks (4.02MB) on 0.00 tape(s).
          DUMP: Protocol to remote tape server botched (in rmtgets).
        rdump: Lost connection to remote host.
          DUMP: Bad return code from dump: 1

Many users responded and the problem was quickly solved. I had been
sending output to stdout (or stderr I believe) which causes rdump
to choke when it is being run. It isn't expecting any output.
For instance, an echo statement in the .cshrc will cause a remote dump
to lose its connection. I assume that this means that various things
will choke when run remotely vis a' vis rsh.

Hence, I would suggest the line( or something like it ):

        csh: if ( ! $?USERS || ! $?PROMPT ) exit
        English: if the variable USERS or PROMPT are NOT set
                 then EXIT.

at the beginning of .cshrc files. This will ensure that if the session/
shell is a remotely run command, the .cshrc will terminate before it sends
anything to stdout or stderr.

Any further information/corrections about this issue can be forwarded to
me and I will gladly update my summary.

Thank you to all those who help:
