how to ping to port

[Nagaraj Dandeboyina_1]

Hello,

can some one suggest me how to ping from local system to remote system using port??

Local IP: 3.4.5.6
Remote ip: 12.13.14.15 port 3299

From local system I am able ping remote system, but want make sure that I can also ping to remote system with port 3299.

How can I check? Syntax??

Thx for ur help.

You can't ping a port, at least not using 'ping'. The way to test if a port is open is with telnet:

telnet 12.13.14.15 3299

If you get connected, then the port is open. If you get "connection refused", then the port is closed.

HTH.

You can also user rpcinfo to see if a program is running on a specific host.
Use "man rpcinfo" to see details.
An example is
rpcinfo -p

You get a list of ports and programs that are running on the host

This works unless the port is an udp port. In that case you can not be certain if it works unless you use the real software that needs to use this port.

But if you can ping the server without packetloss, and there is no firewall in between the two systems, you should be fine.
