Hi folks -

Has anyone out there ever seen or have you ever done anything with IPMI over 
TCP? 

In the spec pretty much the only time they talk about TCP is in:

13.2 Required ASF/RMCP Messages for IPMI-over-LAN

The following class=ASF messages under RMCP must be supported in a system 
implementing the IPMI LAN interfaces over TCP/IP-UDP. 

[…]

ASF Presence Ping message               REQUIRED.

In scans I see lots of systems answering to TCP 623; nmap lists it as 
“oob-ws-http”, but it appears to simply detect the openness of it, not that it 
actually does something.

I’d always meant to look into to this, and I could have sworn I had it working 
awhile back, but I my recent efforts to put the UPD payload of both Get Channel 
Authentication Capabilities and the ASF Ping and don't get a valid response 
back (most often I see something like "00 00 00 02 09 00 00 00 01 00 00 00 00 
00 00 00 00”)… 

So does anyone know about any implementations out there? Is TCP 623 actually 
used for IPMI, or for other OOB protos, or…?  

I don’t have any direct access to a system that uses TCP 623, so I don’t want 
to beat on it too much without knowing more.

Thanks for any RFTMs or whatever -

dan
