It is important to keep the TeamCity agent names unique. If you launch a TeamCity agent with a name that is already used by another agent that is connected to the TeamCity server, the new agent will not show up in the Unauthorized agent list.
To change the name of an agent, change the “name” value in the conf/buildAgent.properties file.
To access the file you need to log into the box.
On a Linux agent
- SSH into the agent,
- Change the “name” value in the /opt/teamcity/conf/buildAgent.properties file.
On a Windows agent
- Remote into the agent,
- Change the “name” value in the C:\TeamCity\conf\buildAgent.properties file.
The location of TeamCity can be different depending on the configuration of the box.
