Re: Problems with GuacamoleHTTPTunnelServlet

Craig,
 
I verified that guacd is running (systemctl status guacd) and then issued the command telnet localhost 4822. I successfully connected.
 
root@guac:~# telnet localhost 4822
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is ^]'.
 
I pressed enter and the connection was 'closed by foreign host'
 
So it appears that 4822 is available on the localhost.
 
Thanks,
 
Jim

Could this be a firewall thing? Can you open a TCP connection to
127.0.0.1:4822?

You obviously won't do anything useful, since you won't speak the
guacd protocol, but that's not the point. Just make sure you can open
a network connection to guacd. If you can't, then FW or perhaps guacd
isn't really opening the port it says it is, etc. will require some
troubleshooting.

Hope this helps,
-Craig
