Ports Used - ESET REMOTE ADMINISTRATOR 4 - ANNEXE 335 Installation Manual

2.1.3 Ports used

The chart below lists the possible network communications used when ERAS is installed. The process EHttpSrv.exe
listens on TCP port 2221 and the process era.exe listens on TCP ports 2222, 2223, 2224 and 2846. Other communications
occur using native operating system processes (e.g., "NetBIOS over TCP/IP").
Protocol Port
TCP 2221 (ERAS listening)
TCP 2222 (ERAS listening)
TCP 2223 (ERAS listening)
If all the program features are in use, the following network ports need to be open:
Protocol Port
TCP 2224 (ERAS listening)
TCP 2846 (ERAS listening)
TCP 139 (target port from the point of view of ERAS)
UDP 137 (target port from the point of view of ERAS)
UDP 138 (target port from the point of view of ERAS)
TCP 445 (target port from the point of view of ERAS)
The predefined ports 2221, 2222, 2223, 2224 and 2846 can be changed if they are already in use by other applications.
To change the default ports used by ERA, click Tools > Server Options... To change port 2221, select the Updates tab
and change the HTTP server port value. Ports 2222, 2223, 2224 and 2846 can be modified in the Ports section on the
Advanced tab.
The predefined ports 2222, 2223, 2224 and 2846 can also be modified during the advanced install mode (ERAS).
