[Tsung] Host key verification failed

[Megan Chinburg]

I too have run into this with master and slave machines on the same  
sub-net.  My steps:
1) Clear out all but the top line (127.0.0.1       localhost) in /etc/ 
hosts file for each master and slave machines
2) From the master SSH to each of the slave machines, using the  
complete network name or IP, not the DNS name.
3) For good measure I SSH'ed from each slave back to the master just  
to make sure /etc/hosts contained the correct information.

And that's it, hope that's helpful, although it sound like you might  
have tried that already.  Best of luck
