    Do you get Error Code 255 when you try to run a RCCE program?

      This should not occur if you are using a system in the SCC Data Center. However, if you are bringing up your own MCPC, you may see this error when you first try to run a RCCE program.

       

      Here is output from running the pingpong example.

       

      YourUserName@YourMachine:/shared/YourUserName$ rccerun -nue 2 -f rc.hosts pingpong

      [1] 13:46:17 [FAILURE] rck00 Exited with error code 255 [2] 13:46:17 [FAILURE] rck01 Exited with error code 255

      pssh -h PSSH_HOST_FILE.4828 -t -1 -P -p 2 /shared/YourUserName/pingpong 2 1.0 00 01 < /dev/null

      [1] 13:46:17 [FAILURE] rck01 Exited with error code 255 [2] 13:46:17

      [FAILURE] rck00 Exited with error code 255 

      This error occurred even though the RockyLake board trained successfully and Linux was successfully loaded on the cores. sccGui came up successfully. The cores responded to a ping. An sccKonsole 0..3 successfully brought up four konsole windows. If you try ssh root@rck00, you get prompted for a password; and if you know the password, you can log in.  You should not get prompted for a password in this case.

       

      That you do is an indication that the ssh certificate is not set up properly. To fix this problem, become root on your MCPC and type

       

      cat /opt/sccKit/.ssh2/openssh_config  >> /etc/ssh/ssh_config
