Everything about Authbind
Open-source system utility
authbind is an open-source system utility written by Ian Jackson and is distributed under the GNU General Public License. The authbind software allows a program that would normally require superuser privileges to access privileged network services to run as a non-privileged user. authbind allows the system administrator to permit specific users and groups access to bind to TCP and UDP ports below 1024. Ports 0 - 1023 are normally privileged and reserved for programs that are run as the root user. Allowing regular users limited access to privileged ports helps prevent possible privilege escalation and system compromise if the software happens to contain software bugs or is found to be vulnerable to unknown exploits.
