Running network services as a non-root user

[appli1]

I heard the port 443 (or anything less than 1024, I think) it needs to be run as root else it wont have the permission to listen on that socket. Can you please somebody else help me by sharing any document for the same.

As a general rule, UNIX based programs that bind to ports less than 1024 must be run as root user. The UNIX kernel enforces this restriction. Read kernel documentation (you can find the docs on any linux distribution)

Best regards,
Horia.

Hi appli1,

for a documentation use the keyword "privileged ports" in google.
