I found some inconsistencies between my RedHat AS 2.1, AS 3, and Fedora Core 3 and 4 servers because of different LAN adapters. mii-diag, mii-tool and ethtool are on all of my servers, and tend to give different results. I ended up trusting mii-diag more than ethtool but ethtool is the only one that runs on a few servers. I wrote an extension which sends me a yellow alert if any card drops from 100-full, or red if a card is not responding. Of course the card not responding is only useful if I have more than one LAN adapter configured, and I'll probably get other alerts anyway. Does anybody have a better (or for that matter any other) way of testing LAN card settings? Are there any other Linux tools than mii-diag, mii-tool and ethtool? Ideally, one program that can understand all devices rather than me having to use different ones on different servers.
The reason for the different tools is due to the ethernet kernel drivers supporting different APIs. SIOCETHTOOL (ethtool) is the newer API with SIOCGMIIREG (mii-diag) the elder.
Maybe this tool will help: http://0pointer.de/lennart/projects/ifplugd/ifplugstatus.8.xml
