[mpich-discuss] FW: SMPD on Linux with firewall turned on

[Jayesh Krishna]

 Hi,
  You might also have to open up the port used by SMPD to listen for
incoming connections (port 8676 by default --- Or use the "-port" option
while starting smpd to specify the port to listen. If you use the "-port"
option with smpd make sure that you specify the same port number when
running your job using mpiexec.)
  Let us know if it works for you.

(PS: If that does not work please run smpd and mpiexec in verbose/debug
mode and send us the output. smpd -d / mpiexec -verbose. Also send us the
complete error message that you get when running your MPI application.)

Regards,
Jayesh

Hi,

I installed MPICH2 on 2 64-bit Linux machines under my home directory.
The firewall of both machines is turned on.
When I ran a program across these 2 machines, I got an error message such
as
"abort: unable to connect to xxx".
So I checked with the system administrator and he enabled 11 TCP ports for
me to use.
The port range is from 12505 to 12515.
Also, I set the MPICH_PORT_RANGE environment variable with the above
range.
However, I still got the same error message as mentioned before.
So, how to fix this problem?

Thank you very much,

-Yucheng
