I have sudo privilege on a Linux PC on the company WAN, which I will refer to herein as the "team PC". I would like to provide unlimited access to a handful of people to the team PC. All others logging in should be limited to only being able to execute the command ssh. This limitation enables users outside of my team to use the team PC as a means to access a group of PCs that are isolated from the WAN and interconnected on a private LAN. The team PC has eth0 connected to the WAN and eth1 connected to the LAN. How do I limit non-team users of the team PC to only being able to execute ssh and not use the system for any other purpose?
