It looks like pcap has a older whirlwind image and failing to run the following command 

   /usr/bin/ssh -a -x   -o Protocol=2 -o StrictHostKeyChecking=no -o
    UserKnownHostsFile=/dev/null -o BatchMode=yes -o ConnectTimeout=30 -o
    ServerAliveInterval=900 -o ServerAliveCountMax=3 -o ConnectionAttempts=4
    -l root -p 22 chromeos15-row2-rack2-host1-pcap "export
    LIBC_FATAL_STDERR_=1; if type \"logger\" > /dev/null 2>&1; then logger

    -> ssh_run(/usr/local/bin/ip link set monitor0 up)\";fi; /usr/local/bin/ip
    link set monitor0 up"
Exit status: 2

I will check if upgrading the pcap to latest R65-10323.83.0 resolves the issue.
