http://issues.apache.org/bugzilla/show_bug.cgi?id=40990 Summary: Cannot bind port or ip address for outgoing UDP socket when using SysLogAppender Product: Log4j Version: 1.2 Platform: Other OS/Version: Linux Status: NEW Keywords: JDK1.5 Severity: normal Priority: P2 Component: Appender AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] I am currently using Log4J with SysLogAppender with the following configuration file: The configuration file I used included the following: ---------------------------------------------------------- log4j.appender.syslog2=org.apache.log4j.net.SyslogAppender log4j.appender.syslog2.SyslogHost=localhost log4j.appender.syslog2.Facility=local2 log4j.appender.syslog2.layout=org.apache.log4j.PatternLayout log4j.appender.syslog2.layout.ConversionPattern=%p (%L) -%m%n log4j.rootLogger=DEBUG, syslog2 ---------------------------------------------------------- I noticed that a random UDP port is being opened by the Java application as shown: --------------------------------------------------------------------------- linux:~ # netstat -lpn Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name udp 0 0 127.0.0.1:514 0.0.0.0:* 15994/syslog-ng udp 0 0 :::21457 :::* 1364/java --------------------------------------------------------------------------- For security purposes, I would like to be able to bind this socket to a configurable port and ip address. I am currently using 1.2.14. Looking at the source code, I noticed that the SysLogWriter currently uses the default constructor DatagramSocket() which assigns a random port number and is bounded to a wildcard address. SysLogWriter.java (line 100 - 107): try { this.ds = new DatagramSocket(); } catch (SocketException e) { e.printStackTrace(); LogLog.error("Could not instantiate DatagramSocket to " + host + ". All logging will FAIL.", e); } I suggest that a fix should be implemented to use a parameterized constructor instead such that users may set configurations such that the socket can be bounded to a user-defined port and/or local address. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
