You will need to get comfortable using a terminal and command-line utilities to do the things you want. netstat can help you verify the web services are running:
root@ospi:~# sudo netstat -ntlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 2250/apache2
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 2078/OpenSprinkler
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 2456/sshd
Shows an apache2 process listening on all network interfaces (0.0.0.0) on port 80 and the OpenSprinkler process listing on port 8080. Verify that you are connecting to the correct ip address. In general, it’s debian running, so searching for “linux …” or “debian …” should help you in the future. Hope that helps.
