           Summary: Feature Request: Add SyslogPort option to SyslogAppender
           Product: Log4j
           Version: 1.3alpha
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Appender
        AssignedTo: log4j-dev@logging.apache.org
        ReportedBy: gunterze@gmail.com


I would like to use log4j's SyslogAppender to emit XML Audit Messages
via  BSD Syslog Protocol (RFC 3164) from various Health care client
and server applications to a central Audit Record Repository, as
specified by Integrating the Healthcare Enterprise (IHE) Integration
Profile Audit Trail and Node Authentication (ATNA) in the IHE IT
Infrastructure Technical Framework. (s. Vol. 1 (ITI TF-1): Integration
Profiles
[http://www.ihe.net/Technical_Framework/upload/ihe_iti_tf_2.0_vol1_FT_2005-08-15.pdf],
 Page 55ff).

There is no explicit requirement by IHE, that an ATNA compliant Audit
Record Repository  has to bind on the UDP port 514 assigned for
syslog, Therefore clients must be configurable, to send Audit message
to the repository host also to a different UDP destination port than
514.

With the current version of log4j's SyslogAppender you cannot use a
different UDP destination port than 514. The attached patches (one for
current trunk, and one for log4j-v1.2.9) would enable to configure any
port number by new option "SyslogPort" - with using 514, as default
behavior.

It's no effort/problem, to use such modified MySyslogAppender and
MySyslogWriter classes as proprietary extension of log4j, but perhaps
a configurable UDP destination port of log4j's SyslogAppender sounds
also useful for others..

Best Regards,

Any thoughts on supporting :portno syntax on the existing syslogHost property? 
So that if you specified syslogHost="syslog.example.com", it would go to port
514 on "syslog.example.com" but syslogHost="syslog.example.com:1514" would go to
port 1514?

------- Additional Comments From carnold@apache.org  2006-08-31 05:17 -------
Committed a slightly different take in rev 438792 to the log4j-1_2 branch and 438801 to the trunk.

Adding a separate "port" property to SyslogAppender (as suggested in first set of patches) was 
problematic since SyslogWriter is created on the call ot setSyslogPort() and order of calling 
setSyslogPort() and setSyslogHost() could be arbitrary when using configurators.

The second set of patches would break support for naked IPv6 addresses which would contain colons 
but would now be interpreted as an address and a port.

The committed patch will use java.net.URL to parse the syslogHost property except when the property 
contains more than one colon and does not start with a left bracket.

The following forms should still be supported:

Host name:    foo.example.org
IPv4:              127.0.0.1
IPv6:              ::1

The following forms are added:

Host and port:        foo.example.org:1514
IPv4 and port:        127.0.0.1:1514
IPv6 (URL form):      [::1]
IPv6 and port:         [::1]:1514

Would appreciate any feedback.
