<p><b>New page</b></p><div>'''/etc/services''' is a system file that details what named services run on which numeric ports.<br />

You may find it tempting to inject information about every IANA port you know about into this file, but DON'T - some of the system daemons rely on the information in this file to run, and you may very well confuse them into inoperability if you dump tons of non-FreeBSD-related information into this file. I personally figured this out the hard way when I replaced a system's /etc/services file with one I downloaded from the 'net, and it caused [[natd]] to refuse to start until I replaced my hacked-up copy with a stock copy.<br />
