Ping against server will work if firewall allows ICMP probes.
If a server service is listening on port N, a simple telnet IP port will tell you that.
Something like :
Code:
:~$ telnet www.unix.com 80
Trying 4.59.125.171...
Connected to www.unix.com.
Escape character is '^]'.
This tells me that 4.59.125.171 has a port 80 open are receiving requests.
For further (security ) analysis nmap is the best tool.
Port Scanning is Not a Crime but acting on its results can be, especially on government and financial sites.
