Do the machines in the hostlist match their network node hostnames?  
What this means is that "uname -n" on melchor returns melchor.  If so, 
does stonith work from the command line?  Try:

stonith -t ssh -p "melchor gaspar" -T reset melchor

from gaspar or vice versa.  If it doesn't, add the -d option to see more 
detailed logging.
