script for df output from multiple hosts

I am trying get "df -k" output from multiple hosts along with their hostnames via ssh, my script is appending the "df -k" output from all the nodes to a single file but not getting the hostnames for those nodes, just wondering how to pass more than one command via ssh or may be someone could come up with better script.

#!/usr/bin/ksh

# df.ksh

echo "\$\# is $#"

echo "\$1 is $1"
read r
while [ $# -gt 0 ]
do
echo $1
read r

if [ $? = 0 ]
then
ssh root@$1 hostname; df -k >> /tmp/df.out
else
echo "No SSH on root@$1" >> /tmp/nossh.out
fi
done

Thanks,
Barkath
