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.

rds-ping
RDS-PING(1) BSD General Commands Manual RDS-PING(1)NAME
rds-ping -- test reachability of remote node over RDS
SYNOPSIS
rds-ping [-c count] [-i interval] [-I local_addr] remote_addr
DESCRIPTION
rds-ping is used to test whether a remote node is reachable over RDS. Its interface is designed to operate pretty much the standard ping(8)
utility, even though the way it works is pretty different.
rds-ping opens several RDS sockets and sends packets to port 0 on the indicated host. This is a special port number to which no socket is
bound; instead, the kernel processes incoming packets and responds to them.
OPTIONS
The following options are available for use on the command line:
-c count
Causes rds-ping to exit after sending (and receiving) the specified number of packets.
-I address
By default, rds-ping will pick the local source address for the RDS socket based on routing information for the destination address
(i.e. if packets to the given destination would be routed through interface ib0, then it will use the IP address of ib0 as source
address). Using the -I option, you can override this choice.
-i timeout
By default, rds-ping will wait for one second between sending packets. Use this option to specified a different interval. The timeout
value is given in seconds, and can be a floating point number. Optionally, append msec or usec to specify a timeout in milliseconds
or microseconds, respectively.
Specifying a timeout considerably smaller than the packet round-trip time will produce unexpected results.
