Dear all,

I am going to move my cluster from behind my university firewall and into the real world. However, I am having some concerns about security especially with regards to tftp. Does anyone know why tftp is installed on the clients and what stops it being used for bot-net style etc. activities should the head node's worldly firewall be breached?

Additionally does anyone know if MPE exists for LAM/MPI, I particularly want the Fortran bindings. It appears that MPE comes with MPICH and can be compiled in programs using LAM/MPI's mpif77, in which case perhaps this could be documented somewhere because it was a little puzzling?!

Thanks in advance,

Regards,

Stuart Archibald.
