[jdev] [jadmin] Important bugfix for jadc2s

Hi!

If you are a Jabber server admin and using jadc2s as your client
connection manager, this is an important bugfix for you, that will
increase the stability for client connections to your server.

The problem existed in jadc2s since 2002-10-22. At this time there has
been introduced an output statment for debugging reasons. The problem
with it is that jadc2s will close the standard output on startup so the
debugging output will be sent to the client that connected on the socket
that got the file descriptor 1 (which is the standard output normally).
If the affected user connected using SSL this will even break the
connection to this user as the client's SSL implementation will notice
that the security layer SSL provides has been broken (the output is send
to the connection without being encrypted by SSL). If the connection
does not use SSL it depends on the client implementation if the extra
CDATA is just ignored or causes an error as well.

To fix the problem, please delete the following line from conn.c in
jadc2s' main directory:
                printf("Reading %d bytes\n", read_len);

A patch against release 0.9.0 of jadc2s can be found at the end of this
mail. If you are using the CVS version of jadc2s, you can simply update
to the latest version.
