Q. I am using InterMapper RemoteAccess to establish a connection to the InterMapper server that is in a remote location behind a firewall. The firewall is configured with port forwarding to route all traffic for port 8181 to the InterMapper server's IP address. When I try to connect, I receive an error that the 'InterMapper server is not available'. If I use a VPN connection, I am able to connect successfully. Is there a way to test whether I am actually connected to the InterMapper server?
A. You can test the connection to the InterMapper server as follows:
Use telnet to connect to the InterMapper server:
telnet xx.xx.xx.xx 8181
- Enter the command <KC_version id="0">0.9</KC_version>
- If you have connected to an InterMapper server, you should see a KR response, such as <KR id='0' response='200'>0.9</KR>.
Note that this doesn't work if you are using a secure protocol for the Remote server. For encrypted connections, use OpenSSL to connect to the InterMapper server:
openssl s_client -connect xx.xx.xx.xx:8181
Paste the <KC_version id="0">0.9</KC_version> command and type Return. You should see a <KR id=xxx> response to indicate that the server is responding.
