The Solaris passwd command wants a terminal.
I don't like expect.
But here is how I changed the root password
Code:
#!/bin/sh
filename="$1"
if [ -z "$filename" ]; then
  echo "usage: $0 hostfile"
  exit 1
fi
while read host <&3
do
  ssh -t "root@$host" "passwd"
done 3< "$filename"

For every host it prompts for an interactive password, two times,
but if you can use copy/paste then it's a matter of paste-enter-paste-enter,...

mkhosts

MKHOSTS(8)						      System Manager's Manual							MKHOSTS(8)

NAME

       mkhosts - generate hashed host table

SYNOPSIS

       /usr/sbin/mkhosts [ -v ] hostfile

DESCRIPTION

       Mkhosts	is used to generated the hashed host database used by one version of the library routines gethostbyaddr() and gethostbyname().	It
       is not used if host name translation is performed by named(8).  If the -v option is supplied, each host will be listed as it is added.  The
       file  hostfile  is  usually /etc/hosts, and in any case must be in the format of /etc/hosts (see hosts(5)).  Mkhosts will generate database
       files named hostfile.pag and hostfile.dir.  The new database is build in a set of temporary files and only replaces the	real  database	if
       the new one is built without errors.  Mkhosts will exit with a non-zero exit code if any errors are detected.

FILES

       hostfile.pag	   - real database filenames
       hostfile.dir
       hostfile.new.pag    - temporary database filenames
       hostfile.new.dir

SEE ALSO

       gethostbyname(3), gettable(8), hosts(5), htable(8), named(8)
