PowerChute Business Edition Agent fails to connect using simple signaling on RHEL 5.x due to SELinux access policy

PowerChute Business Edition (PowerChute) Agent cannot communicate with UPS using a simple signaling cable. The result is that communication is not established and “Unknown Device” appears in the PowerChute Agent Web UI.

Product Line:
PowerChute Business Edition

OS: Red Hat Enterprise Linux (RHEL) 5.x x64, x86
Build: PowerChute Business Edition 9.1.1 and 9.0.3 OEM Basic and 25 Node Deluxe

The problem is caused by Security-Enhanced Linux (SELinux) enforcing an access policy. The policy forbids a library used by the PowerChute Agent from running in its current context. RHEL has SELinux set to "Enforcing" mode by default.

1. Change the security context of the PowerChute library file.
Type the following into the command line:
chcon -t textrel_shlib_t /opt/APC/PowerChuteBusinessEdition/Agent/lib/linux/libNatComm.so

2. Restart the PowerChute Agent.
