I notice you're using ssh and a pipe -- does your shell logon script echo anything to stdout when you connect? I've had that interfere with piped ssh stuff. Most shells provide a way for the logon script to determine "is this an interactive session?" and you can use that to avoid echoing anything that would interfere with non-interactive automation. -- Ian _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
