Re: [Ipmitool-devel] IPMI LAN interface stops working after upgradetoDebian squeeze...

[Andy C. <and...@us...>]

Guys,

It just occurred to me that the OS may be interfering with IPMI LAN by trying to also use the RMCP port 623.  
The Linux portmap service allocates any port that is not in use by the OS, so it does not know about IPMI LAN RMCP port 623.  If the IPMI firmware and OS share an IP, then this could cause conflicts.  

If so, running a service that keeps port 623 allocated will prevent it.  See 
http://ipmiutil.svn.sourceforge.net/viewvc/ipmiutil/trunk/util/ipmi_port.c?revision=199 
for source to a simple service that does this.

If not, it could be a firmware problem.  

Andy

Sorry not yet - I've been totally swamped with other work during the past 2 
weeks - but I do need to look into this again.

no e1000e, it's a Supermicro PDSML-LN2+ but the same happens also on another 
mainboard.

Ouch

If I forget to give feedback, please kick me!
