Ping All

Hi there I wonder if there is a command that I could use to ping all computers on a network or find out what is connected to a network. I have small network that I look after and I thought that a Pabx was connected to it but I don't know the ip address any ideas how to find it.
To know is to see To see is to know.

RE: Ping All

Hi Brian, Saw you in the other gen tele discussions...

I imagine you must have some sort of router on your network, or something that is assigning ip addresses to your machines.

Granted it's not a "ping" per se, but I can usually get a list of all active ip addresses being handed out by asking the router (which is should be at your gateway address.)

Let me know if this helps.

RE: Ping All

Thanks tidewoddy
I have a 5 port switch (this is an intelligent switch and sorts out what goes where and remembers it and does not need programming with IP adress's) connected to a computer running NT server, several of those connections going out over fibre and two on ethernet, one has hub on it upstairs and a couple of connections on that. address are in a file on the server but not the ones I used to be able to get. I think that the only way is to follow each lead out through the network till I have physically traced every connection and seen what piece of equipment is connected.

RE: Ping All

"Does not need programming with IP addresses" sounds suspiciously like it is what is acting as the DHCP server.

I'd still try hooking to it using your gateway address from IE... and see if you get a configuration page.

What brand/model is this switch. We'll see if we can't pull any info up on it.


RE: Ping All

Ping the broadcast address of the subnet the pbx is on, YOU should get a request timed out response. But each of the IP addresses should respond anyway. So follow immediately with an arp -a command this should return the IP addresses of all the responding stations with the mac addresses.

By searching the IANA tables and by a process of elimination you should find the IP address of the PBX.

I have never tried this on Windows XP but it usually works.

It is even better tried from a router if you have one with a cli.

RE: Ping All

I defer to TimRegester. He seems much more on top of it than I.
