I'd never really noticed it; it probably would be helpful to put the output just to make sure things are lining up, and rather than just hand you what I think is going on, this seems like a good time to teach people what little I know of fishing. if the email you're seeing is part of a daily run, it's set by the system and not something you put in as root user (you can do crontab -l as root to verify it's not there), then there's the system cron file in /etc/crontab # Perform daily/weekly/monthly maintenance. 1 3 * * * root periodic daily 15 4 * * 6 root periodic weekly 30 5 1 * * root periodic monthly that seems like a pretty good suspect, man on 'periodic' - If an argument is an absolute directory name it is used as is, otherwise it is searched for under /etc/periodic and any other directories speci- fied by the local_periodic setting in periodic.conf(5) (see below). check the directories root@nexus:/etc/periodic/daily # ls 100.clean-disks 330.news 440.status-mailq 110.clean-tmps 400.status-disks 450.status-security 120.clean-preserve 401.status-graid 460.status-mail-rejects 130.clean-msgs 404.status-zfs 480.leapfile-ntpd 140.clean-rwho 406.status-gmirror 480.status-ntpd 150.clean-hoststat 407.status-graid3 500.queuerun 200.backup-passwd 408.status-gstripe 510.status-world-kernel 210.backup-aliases 409.status-gconcat 800.scrub-zfs 300.calendar 420.status-network 999.local 310.accounting 430.status-rwho that 420.status-network seems like a good candidate root@nexus:/etc/periodic/daily # sh -x 420.status-network ... + echo 'Network interface status:' Network interface status: + flags=-d + netstat -i -d Name Mtu Network Address Ipkts Ierrs Idrop Opkts Oerrs Coll Drop em0 1500 <Link#1> XXX 22874340 0 0 574773 0 0 0 em0 - 192.168.XX.0/ nexus 1172609 - - 540898 - - - lo0 16384 <Link#2> 3749 0 0 3749 0 0 0 lo0 - localhost ::1 0 - - 0 - - - lo0 - fe80::1%lo0 fe80::1%lo0 0 - - 0 - - - lo0 - your-net localhost 3749 - - 3749 - - - + rc=0 and I think you'd find that's a decent match for what you get in your email. ... --
