standards work.
I will be sending the final version of this request to the IANA on
Wednesday, November 12th.
---------
The SSL 3.0 protocol has the broadest implementation of any security
standard to date, with both Netscape and Microsoft using it in their
popular servers and browsers. SSL 3.0 has been submitted to the TLS working
group of the IETF, and is is proceeding out of internet-draft status under
a new name, TLS.
Tim Dierks and I are editors for that working group, Win Treese
&lt;<a href="mailto:treese@OpenMarket.com?Subject=Re%3A%20NEW%20DRAFT%3A%20Regularizing%20Port%20Numbers%20for%20SSL.&amp;In-Reply-To=%3Cv03101406af215a4fc3b3%40%5B157.22.240.12%5D%3E&amp;References=%3Cv03101406af215a4fc3b3%40%5B157.22.240.12%5D%3E">treese@OpenMarket.com</a>&gt; is the working group chair, and Jeff Schiller
&lt;<a href="mailto:jis@mit.edu?Subject=Re%3A%20NEW%20DRAFT%3A%20Regularizing%20Port%20Numbers%20for%20SSL.&amp;In-Reply-To=%3Cv03101406af215a4fc3b3%40%5B157.22.240.12%5D%3E&amp;References=%3Cv03101406af215a4fc3b3%40%5B157.22.240.12%5D%3E">jis@mit.edu</a>&gt; is the IESG area director over the WG.
Tim are I have two documents undergoing revision:
&lt;draft-ietf-tls-protocol-00.txt&gt; &amp; &lt;draft-ietf-tls-ssl-mods-00.txt&gt;, which
were approved during the last working group meeting in San Jose, and are
being merged into one draft as we speak.
One area that I am trying to resolve are the port and port naming issues
with TLS/SSL.
As a transport layer security standard, TLS/SSL can work transparently with
existing application level protocols (such as http, nntp, nttp) without
*any* change to the protocol other than using a different port number. As
an example, the popular http protocol uses port 80, and the SSL enabled
version of http uses 443.
It is possible for a single port to be used for both unsecure and secure
uses, however, this requires two things:
* Changes in the application level protocols which must
be separately adopted by each working group over such
protocols. An example of changes that would allow for
a single port in the FTP protocol is covered in
&lt;draft-murray-auth-ftp-ssl-00.txt&gt;
* Support by firewalls to understand and resolve
use of a single port for both unsecure and secure uses.
It is also possible that there could be a single port/port mapping solution
to allow any protocol to be used with TLS without port proliferation,
however, after considerable discussion in the TLS working group there is no
easy design that resolves both architecture and security issues. We have
agreed to add to the TLS agenda and charter to resolve this problem in the
future.
Thus, until each protocol is revised to allow for authenication under a
single port, or a single port/port mapping solution is architected, we will
require separate ports for TLS/SSL implementations of the most popular
protocols.
There are a number of ports currently registered with the IANA the for use
by the SSL protocol. They are:
https 443/tcp https
ssmtp 465/tcp ssmtp
snews 563/tcp snews
ssl-ldap 636/tcp ssl-ldap
spop3 995/tcp SSL based POP3
As the above registrations are inconsistant, and most don't even mention
SSL or TLS, we would like to get these port assignments and names
regularized in the listing as follows:
https 443/tcp http protocol over TLS/SSL
smtps 465/tcp smtp protocol over TLS/SSL (was ssmtp)
nntps 563/tcp nntp protocol over TLS/SSL (was snntp)
ldaps 636/tcp ldap protocol over TLS/SSL (was sldap)
pop3s 995/tcp pop3 protocol over TLS/SSL (was spop3)
There is also currently a desire among existing SSL implementors to
register a number of additional ports mappings for other protocols such as
ftp. We want to avoid port proliferation as much as possible until we have
a long term solution, so we have limited these requests to those protocols
in which we have recieved commitments from a minimum of 2 independent
implementations by developers.
We have been told that some of these invididual implementors may have
attempted to register ports for these uses of SSL, but as of today they
have not recieved registration for these assignments.
We would like to suggest the following:
ftps-data 889/tcp ftp protocol, data, over TLS/SSL
ftps 990/tcp ftp protocol, control, over TLS/SSL
imaps 991/tcp imap4 protocol over TLS/SSL
telnets 992/tcp telnet protocol over TLS/SSL
ircs 993/tcp irc protocol over TLS/SSL
I also have a question -- who requested the following service? We don't
know if it is our SSL or something else with the same acronym.
naming-iiop-ssl 261/tcp IIOP Naming Service (SSL)
Under your procedures, you ask for answers to the following questions:
1) What is the protocol between the user machine and the server
machine?
It is the TLS 1.0 or SSL 3.0 protocol as defined in
&lt;draft-ietf-tls-protocol-00.txt&gt; &amp; &lt;draft-ietf-tls-ssl-mods-00.txt&gt;.
2) What message formats, types, op codes, sequences are used?
It is the TLS 1.0 or SSL 3.0 protocol as defined in
&lt;draft-ietf-tls-protocol-00.txt&gt; &amp; &lt;draft-ietf-tls-ssl-mods-00.txt&gt;.
3) What functions are performed by this protocol?
Securing and authenticating the transport independently of the application
protocol.
4) Is broadcast or multicast used? If so, how and what for?
No -- TCP only is defined by TLS/SSL at this point, however, we'd like to
at least hold the UDP ports in reserve for the future.
5) Do you want a well-known assigned system port in the range 0-1023,
or a registered user port in the range 1024-65535 ?
They need to be in a the well known range as they are largely being
implemented initially by unix developers who want to be sure that it is the
well-known range.
6) What short name (14 character maximum) do you want associated with
this port number?
ftps-data 889/tcp ftp protocol, data, over TLS/SSL
ftps 990/tcp ftp protocol, control, over TLS/SSL
imaps 991/tcp imap4 protocol over TLS/SSL
telnets 992/tcp telnet protocol over TLS/SSL
ircs 993/tcp irc protocol over TLS/SSL
If there are any questions as to our authority to request such changes,
these changes have been run by the WG Chair, Win Treese
