Todd,

 I had a long explanatory email written, but Thunderbird did something new: It crashed and lost the email.  Oh well.  

/etc/protocols - IP Protocols [read: Internet Protocol, part of the networking layer]
/etc/services  - Services, or rather Protocols which use IP as a means of communication

 SMTP == ip service
 TCP  == ip protocol.

 So, with that in mind, you can use numbers or names in either case, and the x-ref files are /etc/protocols, and /etc/services.

Examples of simple command line lookups:

<snip>
strapped ~ # getent protocols ip
ip                    0 IP
strapped ~ # getent protocols tcp
tcp                   6 TCP
strapped ~ # cat /etc/protocols |grep tcp
tcp     6       TCP             # transmission control protocol
strapped ~ #
</snip>

<snip>
strapped ~ # getent services smtp
smtp                  25/tcp mail
strapped ~ # getent services http
http                  80/tcp www www-http
strapped ~ # getent services https
https                 443/tcp
strapped ~ # cat /etc/services |grep http
# http://www.iana.org/assignments/port-numbers
# http://www.freebsd.org/cgi/cvsweb.cgi/src/etc/services
http            80/tcp          www www-http    # World Wide Web HTTP
http            80/udp          www www-http
https           443/tcp                         # MCom
https           443/udp
gss-http        488/tcp
gss-http        488/udp
http-alt        591/tcp                         # FileMaker, Inc. - HTTP Alternate
http-alt        591/udp
sgi-esphttp     5554/tcp                        # SGI ESP HTTP
sgi-esphttp     5554/udp
http-alt        8008/tcp                        # HTTP Alternate
http-alt        8008/udp
http-alt        8080/tcp                        # HTTP Alternate

I can't make any specific rule recommendations WRT tcrule, given my deplorable luck with setting up QoS on Linux.  However, I hope this helps.


Sincerely,
