Major Bug: UFW stopped thru logrotate

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

Debian: without sytemd

If you run Debian Servers, you read last weeks about security problems of systemd service manager. On several tests i have seen much systems having problems on service starts on boot like on debian, raspian .. This is a result of not clean redesigned scripts of the services by the Maintainers like the Proxy Server “privoxy” Package… For Tests i decided to try the new Debian Fork Replacement DEVUAN  for Desktop and a standard Debian Server Setup without systemd! Howto purge Systemd on a Debian System read this external Wiki: http://without-systemd.org/wiki/index.php/How_to_remove_systemd_from_a_Debian_jessie/sid_installation or try Devuan for Server and Desktop: https://devuan.org/ Remark: […]

Linux: Systemd ignore console-setup settings

If you work on older Laptops and you use a Console only System Setup like on Debian there is a Bug on systemd and the console-setup package since years. After reboot all Font Settings seems gone. But the Settings are not real gone, cause systemd does not pull the settings on boot! How to fix? edit the crontab of root by sudo su – crontab -e insert the /bin/setupcon command on “@reboot” means on every boot! @reboot     /bin/setupcon > /dev/null 2>&1 save and exit, reboot now now the PC should echo big Fonts for old eyes “Terminus 20×12 Frambuffermode”
