Description

When you try to connect to TIBCO iProcess Engine through TIBCO iProcess Workspace Windows it fails to connect to the server and throws the below error.

L044: Failed to connect to the network listener service: Remote system error; Connect request was refused.

Cause: If the permission of the core binaries like swrpcudp and chgpwd in the SWDIR/etc folder is incorrect then it can cause the above error and eventually the connection gets failed.

Environment

TIBCO iProcess Engine (Oracle) TIBCO iProcess Engine (DB2)

Resolution

1) Enable the setuid flag for these two binaries if it's not set correctly.

Example of incorrect permissions and incorrect owner/group for swrpcudp binary:

-rwxrwxrwx 1 pro pro 461926 Apr 5 2016 swrpcudp

For the above binary owner/group needs to be root/staffwar (replace staffwar with your group name, if different) and the proper permissions need to be (-r-sr-s---)

Please run the below two commands to set proper permissions and ownership (replacing staffwar with your group name, if different):

chown root:staffwar $SWDIR/etc/swrpcudp
chmod 06550 $SWDIR/etc/swrpcudp
 

Output:

-r-sr-s---  1 root staffwar 461926 Apr  5  2016 swrpcudp
