Server Monitor tool

Question

Why cant i login to the server monitor tool on the server, also tryed from a remote machine.

Answer 1

Use the local path provided in Server Monitor. To add the entry for Server Monitor running directly on the box that is being monitored, [you can use the localhost/127.0.0.1 path|http://support.apple.com/kb/TA24514] or the local system option within the Server Monitor menus.
I'd encourage setting up a VPN solution here on your firewall, and not opening up the IPMI path through any firewall. Low-level console and similar hardware-level access can be a powerful attack vector, whether for a remote user that guesses right or for a currently- or formerly-authorized user that goes rogue. VPNs have various advantages, not the least of which is that you don't have to punch gazillions of protocol-specific holes through a firewall to get work done. And you can more centrally and more easily authorize (or de-authorize) specific remote access, given a decent firewall.
If you do want to expose your IPMI to the wilds, here's the [Apple Well-Known Ports List|http://support.apple.com/kb/TS1629], and you'll find the IMPI LOM stuff and Server Admin listed in there.
And for completeness, here is the general [LOM configuration sequence|http://support.apple.com/kb/HT2773]. Remember to physically pull the plug to power-cycle the LOM itself; the LOM stays powered when the box itself is shut off. Pulling the mains for some seconds forces the LOM to reload its configuration and its network settings when power is restored.
Why localhost? NICs can serve multiple network addresses, and you can't get an IP packet out from one address on the box on the NIC, and back in the same NIC on a different address. Ethernet just doesn't work that way. And the host and the LOM can use the same NIC, though with different addresses.
