-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I was working at my desktop machine. My little server machine, media server, was playing the internet radio with Kodi. I went to the kitchen to put the dinner on the oven. On return, the media server had rebooted and was asking for login. There is no trace in the syslog: <1.5> 2021-01-23T21:15:03.643324+01:00 Isengard Sistema - - - Logging the current external IP= (omitted) <3.6> 2021-01-23T21:16:56.732717+01:00 Isengard systemd 1 - - Started Daily Cleanup of Snapper Snapshots. <3.6> 2021-01-23T21:16:56.873624+01:00 Isengard dbus-daemon 1109 - - [system] Activating service name='org.opensuse.Snapper' requested by ':1.1048' (uid=0 pid=5447 comm="/usr/lib/snapper/systemd-helper --cleanup ") (using servicehelper) <3.6> 2021-01-23T21:16:57.131185+01:00 Isengard dbus-daemon 1109 - - [system] Successfully activated service 'org.opensuse.Snapper' <3.6> 2021-01-23T21:21:56.728956+01:00 Isengard systemd 1 - - Starting Cleanup of Temporary Directories... <3.5> 2021-01-23T21:21:56.875752+01:00 Isengard systemd-tmpfiles 5561 - - [/usr/lib/tmpfiles.d/net-snmp.conf:1] Line references path below legacy directory /var/run/, updating /var/run/net-snmp → /run/net-snmp; please update the tmpfiles.d/ drop-in file accordingly. <3.5> 2021-01-23T21:21:56.879004+01:00 Isengard systemd-tmpfiles 5561 - - [/usr/lib/tmpfiles.d/radvd.conf:1] Line references path below legacy directory /var/run/, updating /var/run/radvd → /run/radvd; please update the tmpfiles.d/ drop-in file accordingly. <3.5> 2021-01-23T21:21:56.879901+01:00 Isengard systemd-tmpfiles 5561 - - [/usr/lib/tmpfiles.d/samba.conf:1] Line references path below legacy directory /var/run/, updating /var/run/samba → /run/samba; please update the tmpfiles.d/ drop-in file accordingly. <3.5> 2021-01-23T21:21:56.883365+01:00 Isengard systemd-tmpfiles 5561 - - [/usr/lib/tmpfiles.d/svnserve.conf:1] Line references path below legacy directory /var/run/, updating /var/run/svnserve → /run/svnserve; please update the tmpfiles.d/ drop-in file accordingly. <3.5> 2021-01-23T21:21:56.887213+01:00 Isengard systemd-tmpfiles 5561 - - [/usr/lib/tmpfiles.d/tmp.conf:13] Duplicate line for path "/var/tmp", ignoring. <3.5> 2021-01-23T21:21:56.888626+01:00 Isengard systemd-tmpfiles 5561 - - [/usr/lib/tmpfiles.d/var.conf:21] Duplicate line for path "/var/lib", ignoring. <3.5> 2021-01-23T21:21:56.889240+01:00 Isengard systemd-tmpfiles 5561 - - [/usr/lib/tmpfiles.d/var.conf:23] Duplicate line for path "/var/spool", ignoring. <3.6> 2021-01-23T21:21:56.965040+01:00 Isengard systemd 1 - - Started Cleanup of Temporary Directories. <1.5> 2021-01-23T21:30:03.251921+01:00 Isengard Sistema - - - Logging the current external IP= (omitted) <3.6> 2021-01-23T21:33:54.528052+01:00 Isengard smartd 1103 - - Device: /dev/sda [SAT], SMART Usage Attribute: 189 Airflow_Temperature_Cel changed from 41 to 46 <3.6> 2021-01-23T21:33:54.529239+01:00 Isengard smartd 1103 - - Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 41 to 46 <3.6> 2021-01-23T21:33:54.603175+01:00 Isengard smartd 1103 - - Device: /dev/disk/by-id/wwn-0x5000c5009399305f [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 66 to 65 <3.6> 2021-01-23T21:33:54.603840+01:00 Isengard smartd 1103 - - Device: /dev/disk/by-id/wwn-0x5000c5009399305f [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 34 to 35 <1.5> 2021-01-23T21:45:03.043504+01:00 Isengard Sistema - - - Logging the current external IP= (omitted) 2021-01-23 22:06:23+01:00 - Booting the system now ================================================================================ Linux Isengard 5.3.18-lp152.60-default #1 SMP Tue Jan 12 23:10:31 UTC 2021 (9898712) x86_64 x86_64 x86_64 GNU/Linux <3.6> 2021-01-23T22:06:24.780509+01:00 Isengard systemd 1 - - systemd 234 running in system mode.

AES-NI & encryption
by James Knott 01 Feb '21

01 Feb '21

I run pfsense for my firewall/router and it supports the AES-NI instructions for encryption. Does the same happen with openSUSE, with browsers, VPNs or other? https://en.wikipedia.org/wiki/AES_instruction_set#x86_architecture_processo…
