Q: I have a managed switch that I can telnet to . but I forgot what I had IP assigned. Is there a way I can ping each IP and see whats going on? Now I only have two computers on the switch . When I tracert the other computer, the switch does turn up.
Best Answer: With all due respect, the first answer is totally wrong. KVM over IP switches do not have identical functionality to RDP or logmein. All that a KVM over IP switches does compared to a normal KVM is change the location where the keyboard, mouse, and monitor can be located. Rather than having to, for instance, go down to the server rack, and use the keyboard, mouse, and monitor there, you connect to the KVM via the network and do your work remotely.
Now, if the server is running normally, you can of course just use RDP, or VNC, or logmein or whatever. But, if you want to watch the server reboot, or reboot and go into BIOS config, or basically anything that's happening when the operating system isn't running, any of those software solutions won't work.
You actually brought up a feature that doesn't actually have anything to do with where the KVM works over IP or not. We have a KVM in one of our racks that uses the CAT5 cable from the KVM to the server. There is a dongle of sorts at the server that connects to the video port and to a USB port. You connect a CAT5 cable to that dongle that runs to the KVM. So, the physical connection between the KVM and the server uses a CAT5 cable, but that has nothing to do with how you connect to the KVM. Ours actually is not a KVM over IP. The maximum length of that CAT5 cable depends on which KVM switch you have, but I think ours can go up to 100 ft.
Now, if on top of using CAT5 cables to connect the servers to the switch, you want to connect to the KVM over IP, that's another story. You just need to buy a KVM with that added functionality. At that point, the KVM is just another network node, and just gets attached to your normal network switch like any other computer, printer, etc.
By the way, this won't be cheap, either. An 8-port Belkin KVM switch with the functionality you want is $800 plus $80/server for the interface module.
Going even farther, there are remote access technologies built into servers such as the HP iLO or the Dell DRAC that allow you to not only control the server remotely, but also to phyically power the server off and on.
Re:You need a null modem cable. God I hate it when they do that! You can either buy a null modem cable or you can buy a null modem adaptor.

Re:What kind of switch is it? If it's a Baystack/Nortel than try ctrl+c for the main menu. Other than that it's pretty standard: 8,N,1,9600, no flow control. Some of the older Baystacks were ctrl+y or something like that. I can't recall right now and I usually just try ctrl+ a bunch of stuff until the menu comes up.
Re:heh.. problem is that I cant console into it for some reason. It might be the cable, or my hyperterminal settings.
Re:Can you console into it? YOu can with most managed switches and from there you can get the ip rather easily.
Re:Do you telnet into by name? Then lookup the name. If you telnet into it by IP I'm gonna have to laugh a little.
If you're on a Windows box you can just ping it by name and it should resolve the IP for you.
Finally, it this isn't what you're after then tell us what kind of switch it is.
Ack! Nevermind. I miss understood what your wrote when you said you can telnet into, meaning it's possible for you to do so, but that you forgot the IP so you can't.
Yeah, console in and you can get it that way.
Re:WSPing didnt do the trick :-/
Re:Try WSPing ProPack from Ipswitch. (http://www.ipswitch.com) It's got a "scan range" that will ping all the IP's in a subnet. That should find it for you. Or you can just write a little batch file to do it, or something…
