If you use modsecurity2 Plugin Filter on a Apache2 / Apache24 Setup then on my Blogs Gutenberg fails to SAVE Pages and Drafts. Workaround: Install the old but useful “Classic Editor Plugin” and replace Gutenberg for all Users! Background: It seems the lastest stable mod_security2 Rules not modified for Gutenberg post urls!

On Debian Sid i have seen that ufw service is stopped on logrotate!! Its a bad known bug! Workaround: Set all Services like Dovecot, Postfix to listen on LOCALHOST (127.0.0.1) if not needed over Internet Enable ONLY encrypted AUTH (Login) to Postfix! (TLS 1.2) Disable unneeded Services ! like Samba, FTP… move config from /etc/logrotate.d/ufw to /root/ to disable ufw logrotate !! edit /etc/ufw/ufw.conf set LOGLEVEL to “off” restart the Server and check open Ports next Days from outside with: $sudo nmap -PN my.server.com

If you use a TP Link Router like 3600, 4300 or a other brand with ATH9K Chipset you should upgrade to OPENWRT 18.06 with Kernel 4.9 Tested: OpenWrt 18.06.0 r7188-b0b5c64c22 / LuCI openwrt-18.06 branch (git-18.210.69179-6df9a57) – Atheros AR9344 rev 2 cause: more stable less load no ath9k Wifi Lookup on high transfers Same seen on other TP Link Routers like 841 Series, remark last Version 13 not supported Hope that the Freifunk Software will be updated fast!

If you use a Gigablue SAT Box,after some weeks enigma2 will hang up: edit root crontab: $crontab -e insert: 0 1 * * * killall -9 enigma2 && sleep 5 && init 3 && /etc/init.d/samba restart 5 1 * * * wget -O /dev/null -q "IP-OF-GIGA-Box/web/powerstate?newstate=0&type=0" This will restart enigma2 Service, Samba and Webinterface too! Then Enigma is set to Standby! That kodi can access the TV Bookmarks to view TV over LAN! If Standby is not set Kodi hangs!
Under heavy load the Debian Kernel 4.14-13 crashes on high memory load and let the CPU freeze. Not really funny so rollback to older version
