How reproducible:


Steps to Reproduce:

1. set up a user on hostB so that user on hostA can rsh to hostB without a
password prompt

2. create the following script on hostA as "doit":


  while true
        echo -n $m
        while [ $n -gt 0 ]
                /usr/bin/rsh $system echo hello >/dev/null &
                [ $? -ne 0 ] && exit 1
                echo -n .
                n=`expr $n - 1`
        m=`expr $m + 1`

3. on hostA, run: doit hostB

Actual results:

  within two minutes you get "poll: protocol failure in circuit setup" errors

Expected results:

  no errors
