In order to assist with troubleshooting, Sureview build a trace listener into each service. This writes out to a port which can be accessed via a telnet command. This allows users to see what the service is doing and identify relevent information and errors.
Telnet Example for SMTP Reciever
telnet localhost 16010
These trace port are only accessible from directly on the machine that the service is running and requires no ports to be opened on the firewall.
Disabling trace ports
If you require trace ports to be disabled due to vunerability scans detecing non-standard ports it will require a user to edit the config file and comment out the setting.
Config files for services are labeled as:
SV[ServiceName].exe.config e.g SVSmtpReceiver.exe.config
Inside each config file is a settings xml node.
The user will need to comment out the setting:
<add key="TracePort" value="16010"
To comment out a key you will need to type <!-- before the setting and --> after
<!-- <add key="TracePort" value="16010" /> -->
After the setting has been commented out, the relevent service will need to be restarted from the windows services tool.
