With Supermicro server you usually have two options: 1. IPMI Serial over LAN 2. IP-KVM provided by BMC 1. IPMI SOL can be used from other BSD/Linux host using ipmitools ipmitool .... sol activate IPMI SOL should be configured on both IPMI (via ipmitool) and server (/boot/loader.conf, /etc/ttys). 2. IP-KVM can be accessed using Java application from BMC web interface or using IPMIView: ftp://ftp.supermicro.com/utility/IPMIView/Linux/ Which method do you use? Is keypress repeated always or only when server is overloaded? Anyway both methods should work, but has own issues: 1. Remote user for ipmitools can be activated only via web interface (and NULL user can't be used). Default user ADMIN work via ipmitool too, but I wanted to create separate users. 2. Java app from server's BMC web interface works only with some JRE versions (long time ago it worked only with Sun/Oracle JDK and failed to work with OpenJDK). IPMIView worked better for me (with less glitches) than app from BMC web interface. I recommend to use IPMIView. 3. It is more reliable and secure to use dedicated IPMI LAN port on server.
