You can ping to that server and check if it is online or
not. You can take a console of the server,or simply try to
telnet/ssh to that machine.

Answer / bc
Some times icmp requests might be blocked on the server. So
server might not respond to ping requests.
So better option is try to telnet to various ports on the
server. If it's a webserver 80 port will surely be UP.
So
telnet <server-ip> 80
Will surely yield some results.

1 Method: which is generally used is ping command......
ping ip address
2 Method: if your ping command returns 0 packet received...
than we can try by either SSh or telnet command to remotly
login on that server..(use telnet command with port no which
is open using nmap serverip address)
telnet ip-address portno
butsome times in linux administrator can block this service
from outers network.

Answer / girish g pillai
Ping could be disabled on the remote machine.
Telnet cannot be used as a reliable method, because we have
to know the services running on the machine to telnet to
that port.
nmap would be a reliable method, but normal nmap checks are
disabled in the network level, so it would be good to run
nmap in stealth mode.
nmap -sS <IP Addr>
