How to change the default ports used by EventLog Analyzer?
Procedure to change the default web server port:
- Edit the server.xml file present in <EventLog Analyzer Home>/conf directory.
|
<Connector acceptCount="100" connectionTimeout="20000"
debug="3" disableUploadTimeout="true" enableLookups="false"
maxSpareThreads="75" maxThreads="150" minSpareThreads="25"
port="8400" redirectPort="8443"/>
|
- Change the port number in the following line to the desired port number:
port="8400"
- Save the file and restart the server.
Procedure to change the default UDP port for Syslog:
By default, EventLog Analyzer listens to the UDP ports 513 and 514 for syslogs.
- Stop the EventLog Analyzer service.
- Edit the file runsec.bat, which is located at <EventLog Analyzer Home>bin folder.
- Edit (in notepad) the entry "binSysEvtCol.exe -loglevel 2 -port 513 514" for default port change and remove ports that are not required. For example, if you do not want port 514 as default, the edited line will look like: "binSysEvtCol.exe -loglevel 2 -port 513".
- In case, you do not want any default port to be listening for Syslog, remove the "-port" option in the above line.
- After saving the runsec.bat, restart the EventLog Analyzer service/server for the changes to take effect.
Procedure to change the default PostgreSQL port:
- Edit the database_params.conf file located under <EventLog Analyzer Home>conf directory .
- Change the port number in the following line to the desired port number:
url=jdbc:postgresql://localhost:33335/eventlog?stringtype=unspecified
- Save the file and restart the server.
Permission to access PostgreSQL to troubleshoot
- Open the pg_hba.conf file which is under <EventLog Analyzer Home>pgsqldata directory and add the line
host all all <IP address of the remote machine to be used to trouble shoot>/32 trust
after the line
host all all 127.0.0.1/32 trust
and save the file.
