Hi,

I am running Ubuntu 7.10 32-bit (Vista dualboot) and have a ssh-related problem, which solution I haven't found browsing forum posts. I cannot ssh into my machine (hostname is machine47), i.e. the command 'ssh machine47' returns

"ssh: connect to host machine47 port 22: Connection refused"

Consequently, I guess, the script 'foamSystemCheck' fails, returning the following error message:

"Checking basic system...

-----------------------------------------------------------------------

Shell: bash

Host: machine47

OS: Linux version 2.6.22-14-generic

Ping_machine47 Successful

Test_ssh: Unsuccessful, connection refused*

FATALERROR: No remote shell available.

FoamX requires passwordless

'ssh' and/or 'rsh' to the current host.

Contact your system administrator if you intend

to run FoamX."


I would be very thankful if somebody could help me back on track.

Thanks Djemai. The command 'sudo apt-get install ssh' solved the ssh configuration issue and OF installed fine.

If you are working locally and not using FoamX you don't need rsh/ssh.
