Issue/Introduction
The installer is copied to /tmp directory and the installer script is invoked from that path
Simply installing the agent w/o running it breaks the ssh forwarding, the agent does not need to execute to reproduce the problem
The issue is not reproducible when AllowAgentForwarding parameter is explicitly set to yes in the sshd config
The issue is not reproducible when the agent is installed from any directory other than /tmp (e.g. installing it from /home/<user>/, /tmp/<subdir>, etc. doesn't break the ssh forwarding)
Environment
CB PSC Linux Sensor: 3.4.2
Ubuntu 16.04
Cause
Issue with agent forwarding configuration when installing from /tmp/
Resolution
Carbon Black is aware of the issue and is working on a resolution
Additional Information
Workaround Install agent from a directory other than /tmp/
