[mpich-discuss] unable to get host address

[Alex Theiakos]

Dear Nicolas,

First thx for your support, I really appreciate it!

Now to your questions,

--I'm running on 10.6.6 all updates done.

--Hosts file is clean, exactly the same as yours.

--I believe i'm not behind a NAT, with ifconfig i'm getting ip's on en0 and en1 profiles (other than the usual 195. or 10. ones )

--I tried the scutil command but nothing changed, still getting the same output.

Just for the record I compiled the openmpi (no offense guys) this morning to see if it would work and it does...
However I would like to check MPICH2, if we can manage to work this out...

Regards,

Alex
