I have two nodes connected via ethernet: itioc5 and itioc1
I have the following in my nodelist file:
group main
host itioc1
host itioc5
I am using the following command:
/usr/people/douglas/programs/NAMD_2.9_Linux-x86/charmrun +p12
/usr/people/douglas/programs/NAMD_2.9_Linux-x86/namd2 ++verbose
mdrun.conf
I get the following output:

I'm not sure but I think the "Starting ssh itioc5 -l douglas /bin/sh
-f" lines has something to do with it. If I run the command "ssh
itioc5 -l douglas /bin/sh -f" it also hangs. If I run "ssh itioc5 -l
douglas" then it logs me in just fine (without asking for a password).
Similarly the command "ssh itioc5 -l douglas -f pwd" works fine, with
the expected directory name returned.
What exactly is happening at the "Waiting for 0-th client to connect." stage?
Many thanks in advance for your thoughts.
cheers,
Doug
