how do you ping an ip address and port number

borosp1 · 08-15-2005, 02:44 PM

Is there any ping cmd or tool that allows for pinging an ip address thats not a default port?

i.e 192.168.xxx.x on port 1521

Basically we are having a problem where I am timing out when I try to hit an oracle database on another server. I can ping the server IP and it returns 100%, but a tnsping of the db times out. Oracle uses port 1521 for communication.

I think this is not feasable because probably the pinging of an ip of a server is on a designated port.

I do not believe you can ping a specific port. You can count hops, resolve address to hostname, number of echo requests to send etc...

ping uses ICMP, which is part of the IP protocol, not UDP or TCP (in which ports are established).
you can use programs that scan hosts for open ports, like superscan.exe, to see if its a network communication problem.

edit:
also, make sure your tnsnames.ora is set properly.

you can't "ping" a port per say as that is ICMP, not udp/tcp.

Easiest way is to telnet to the port "telnet 10.1.1.1 1521"

If it is immediately disconnected then the port is on a live host and is closed (or a firewall sent you a TCP reset). If a window opens the port is open. If it times out then you didn't reach the host/port (or a firewall dropped the packet)

yup. you can't ping a port, but you can attempt to access the service via telnet as spidey said.

can you restart oracle?

Thanks guys for the quick replys. The Oracle Server is working its just I cant ping from the 2 webservers. On a 3rd application server the pinging of the database works fine.

I think its a network issue relating to the firewall and ports not being opened.

First rule of networking.

1) It is never a network problem.

Second rule

2) Always the server/application, never a network problem. The network is fine. Nothing to see here, move along.
