Connecting to a CVS-server on port *2402*
Torben B. Christensen
All the manuals seems to assume that port 2401 is always used for a
pserver connection. Well, not on our AIX-box...
So, how do I connect to an alternate port? I know from our WinCvs
clients that it can be done, but how do I persuade the standard UNIX-
client? My best guess would be changing the CVSROOT - just can't
figure out how...

There's a patch floating around that allows you to export
CVS_CLIENT_PORT=2402 before running the client that I've used with some
success. I've attached the copy I've used which works against CVS
1.10.x. If I remember right this is from Derek Price at Open Ave.

But I still wonder if configuring-by-patching really is necessary?
I quote from Karl Fogel's CVS-book:
"Before running through the steps needed to set up the password server,
let's examine how such connections work in the abstract. When a remote CVS
client uses the :pserver: method to connect to a repository, the client is
actually contacting a specific port number on the server machine -
specifically, port number 2401 (which is 49 squared, if you like that sort
of thing). Port 2401 is the designated default port for the CVS pserver,
although one could arrange for a different port to be used as long as both
client and server agree on it. "
Sadly, KF doesn't reveal HOW to arrange it...

There _is_ an even better fix if you feel like downloading the dev version of the source from the CVS repository. It allows you to specify an alternative port as part of CVSROOT. There's a small issue yet with the treatment of the password file, but it's no show stopper and I should have it fixed in another day or two. Of course, you'll still have to compile that.

If you want to setup multiple pserver processes on a single
host and access each one, then the patch to allow
CVS_CLIENT_PORT will be necessary.
If you only want to change the port used from the default,
then change the port for cvspserver in /etc/services. The
clients, and inetd will resolve the mapping from there.

in /etc/services. It wasn't being used( unless you happen to be
using that service, and as I recall it was something very esoteric ).
I would recommend just changing your /etc/services to
point at cvs at port 2401

IIRC, it was something to do with printing in a cluster, which
could be vital to some sites.
You could complain to IBM. They might listen, but I don't see
them doing much about it. They are the people that did this
in the first place. (On the other hand, looking at /etc/services
on the AIX box I've got access to, it does list
writesrv 2401/tcp # Temporary Port Number
so maybe IBM would be willing to move it to a non-reserved port
number. In a later OS version.)
The issue with 2401 is not that the server can't be changed to
another port with some quick config file changes, but that the
clients know that 2401 is the right port. (Similarly, I don't
know what uses writesrv, and that would be practically impossible
to change locally.)

There are reasons I don't like AIX. This is one of them. It flunks
"Plays well with others".

Hi Larry (and other repliers)
I did consider changing the standard IBM setup, but gave it up (David
Thornley's reply explains excactly why - thank you, David).
I'm no AIX expert and I want to sleep at night... so I went for a free port.
Personally I think that when a program *insists* on using a certain port it
is as annoying as when a program insists on installing in a certain
directory on your C:-drive!
And to wrap it all up: I understand from Derek Price that a future release
of CVS will allow you to change the port, so for now I'll just build a
patched version and wait...
/Torben
PS. Sorry that I've created two threads on the same issue - if this creates
yet another thread I hope someone will explain a beginner how to avoid it

Rumor has it that there's a patch available from IBM to fix their
mistake.

I would agree with you except that there is no official registration
authority for directories on the C: drive, whereas there *is* an
official registration authority for TCP/IP port numbers. IBM has no
business using a port number in the registered range without registering
it, particularly not one that's already registered to someone else.
That said, I do support Derek's change to allow specifying the port
number in $CVSROOT, but I strongly encourage you to let IBM know you're
not happy with the situation. They need to understand that such
antisocial behavior is unacceptable.
