What is portmap FOR LINUX?

Portmap

Portmap is part of the ONCRPC software collection that helps different computer programs talk to each other through remote procedure calls. Pretty neat, right?

How Portmap is Used

This tool is super popular among systems like NIS and NFS. It plays a big role in making sure they can work together without a hitch. If you’re dealing with these systems, you’ll likely come across portmap.

Customizing Your Portmap Setup

You can tweak some settings when compiling portmap. Here are a few options:

• NO_TCP_WRAPPER: If this is set and not empty, it means tcp_wrappers won’t be used.


• USE_DNS: When this option is active, tcp_wrappers can check connections based on hostname and IP address. Just be careful! Only use this if you’re sure that using 'gethostbyname' won't accidentally call portmap.


• RPCUSER: If you set this up, portmap will look for the user with getpwnam before listening for messages.


• DAEMON_UID: You can change the default UID by setting this to a number; it defaults to '1'.


• DAEMON_GID: This works like DAEMON_UID but for GID instead.
