We're using Guacamole for RDP sessions, but as we have several workstations located around the city. Each time a user connects it returns:

ClientAddress: 10.0.0.1XX (Guacamole Server IP)
ClientName: Guacamole RDP

I need to know if there's a way for each connection to give me the IP and the real name of the workstation that connects through Guac.

E.x. Instead of 10.0.0.190 I need 192.168.1.XX and the ClientName TAG10 (every workstation has its own hostname.)

Thanks!

For guacamole version 1.0.0 and above, you will need to configure RemoteIpValve in your tomcat in order to see the source IP.

Firstly, make sure that your proxy send X-Forwarded-For header. For example (in nginx):

location /guacamole/ {
    proxy_pass http://HOSTNAME:8080/guacamole/;
    proxy_buffering off;
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $http_connection;
    access_log off;
}

Next, configure RemoteIpValve in tomcat. It is used to pass through remote IP address to the application.

Go to tomcat conf directory, and edit this file (conf/server.xml). Under the <Host> section, add the following:

<Valve className="org.apache.catalina.valves.RemoteIpValve"
               internalProxies="127.0.0.1"
               remoteIpHeader="x-forwarded-for"
               remoteIpProxiesHeader="x-forwarded-by"
               protocolHeader="x-forwarded-proto" />
