vixen has a normal, or empty config and as such has no firewall, dasher has a number of firewall rules configured which could easily be the cause of the problem on these two machines. To be able to run OpenMPI across these two machines you'll need to disable the firewall on dasher.
To disable the firewall the command (as root) is "service iptables off" to turn it off until next boot or "chkconfig iptables off" to do it permanently from the next boot, obviously you should check with your network administrator before doing this.
