„nodm“: Improved „restart“ behavior

I currently maintain an experimental spin-off of the „nodm“ minimal display manager written by Mr. Enrico Zini: Spin-Off project site: https://git.devuan.org/tilt/nodm As has been reported, in recent installations of „nodm“ from Debian packages up to version 0.11.1-3 (Debian unstable), the „restart“ action of the sysvinit-script does not reliably restart „nodm“.

Ad-Blocking with BIND9 and NGINX

In my intranet, where hosts are in a subnet 192.168.2.0/24 and domain names in a domain mydomain, I use BIND9 as DNS, running on host intradns.mydomain , and NGINX as a webserver running on intraweb.mydomain.

Ubuntu 14.10 cryptswap1 With LVM Stops Working After Reboot

Today I rebooted an Ubuntu 14.10 that was set up with LVM and encryption. It was unable to use the encrypted swapspace cryptswap1, which ultimately halted the boot procedure with a prompt (S for skip and M for manual resolution, i.e. single-user-mode prompt). The problem appears to be that the UUID (blkid) of the designated […]

Filtering and Rate-Limiting ICMPv6 on a GNU/Linux Server

Introduction ICMP (Internet Control Message Protocol) in IPv6 is used for a variety of purposes. As opposed to IPv4, support for some of the applications of ICMP by nodes participating in an IPV6 network is mandatory.
