In my experience you need to ssh back and use keychain to facilitate 
passwordless ssh:
 i.e., in both examples, replace the right-hand side of the pipe with:
 | ssh machA '/bin/dd obs=63k of=/dev/rmt/1ln'"
i.e., try:

1. command="/usr/sbin/ufsdump 0fb - 126 df -k|grep '^/dev/dsk/'\
|awk '{print $6}' | ssh machA '/bin/dd obs=63k of=/dev/rmt/1ln'"

2. command="/usr/sbin/ufsdump 0fb - 126 / \
 | ssh machA '/bin/dd of=/dev/rmt/1ln obs=63k'"
