On several linux machines (some old custom variant of gentoo) I have huge wtmp files, up to gigabyte in size. After some experiments I know that there is rpc.statd daemon running on all servers and there is monitoring running with rup command. Monitoring server runs rup every minute with list of all machines; so statistics are collected.After each run of rup the wtmp file is getting bit larger.My question: Should rpc.statd update wtmp and what will it write into wtmp? My last command does not extract anything about rup, rpc.statd from wtmp.
Should rpc.statd write anything into wtmp?
