Gary Gregory resolved LOG4J2-1604.
----------------------------------
Resolution: Fixed
[~colinh],
I've redone the servers so that they have a proper command line instead of the
positional arguments at fixed indices.
The new way to use the servers is:
{noformat}
Usage: org.apache.logging.log4j.core.net.server.TcpSocketServer [options]
Options:
--config, -c
Configuration file location (path or URL).
--help, -?, -h
Prints this help.
Default: false
--interactive, -i
Accepts commands on standard input ("exit" is the only command).
Default: false
--localbindaddress, -a
Socket server port. See
http://docs.oracle.com/javase/7/docs/api/java/net/ServerSocket.html#ServerSocket(int,%20int)
--port, -p
Socket server port. See
http://docs.oracle.com/javase/7/docs/api/java/net/ServerSocket.html#ServerSocket(int,%20int)
Default: 0
{noformat}
and:
{noformat}
Usage: org.apache.logging.log4j.core.net.server.UdpSocketServer [options]
Options:
--config, -c
Configuration file location (path or URL).
--help, -?, -h
Prints this help.
Default: false
--interactive, -i
Accepts commands on standard input ("exit" is the only command).
Default: false
--localbindaddress, -a
Socket server port. See
http://docs.oracle.com/javase/7/docs/api/java/net/ServerSocket.html#ServerSocket(int,%20int)
--port, -p
Socket server port. See
http://docs.oracle.com/javase/7/docs/api/java/net/ServerSocket.html#ServerSocket(int,%20int)
Default: 0
{noformat}
This requires the addition of JCommander on the classpath:
{noformat}
<dependency>
<groupId>com.beust</groupId>
<artifactId>jcommander</artifactId>
<version>1.48</version>
</dependency>
{noformat}
Please try with the latest 2.6.3-SNAPSHOT from
https://repository.apache.org/content/repositories/snapshots/
If that works for you, please close this ticket.

> Key: LOG4J2-1604
> URL: https://issues.apache.org/jira/browse/LOG4J2-1604
> Project: Log4j 2
> Issue Type: Question
> Components: Core
> Affects Versions: 2.6.2
> Environment: Linux geotst01 2.6.32-504.3.3.el6.x86_64 #1 SMP Wed Dec
> 17 01:55:02 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
> Reporter: Colin Hillman
> Assignee: Gary Gregory
> Priority: Minor
>
> I've been using the log4j version 1 SocketServer in background without
> problem. Changing to the TcpSocketServer works in foreground, but when I put
> it in the background, it shuts down. I've managed to get it working
> redirecting input from /dev/zero but as this will give continuous nulls, I'm
> not sure it's an ideal solution:
> exec $JAVA_HOME/bin/java -cp
> $LIB_DIR/log4j-api-2.6.2.jar:$LIB_DIR/log4j-core-2.6.2.jar \
> org.apache.logging.log4j.core.net.server.TcpSocketServer \
> $\{LOGPORT} $\{BASEDIR}/etc/log4j2.xml </dev/zero >/dev/null 2>&1 &
> Is the code intended to be used in background and, if yes what's the
> recommended way to launch TcpSocketServer? Could a parameter be added to make
> it a daemon not needing input?
