Telnet not working on Ubuntu 20.04 #networking #server #telnet #xinetd #inetd

#openbsd #sh #magic @prahou @ParadeGrotesque @solene sorry, does anyone know why enabling #inetd in /etc/rc.conf.local and enabling #ntalkd in /etc/inet.d and starting inetd isn't sufficient to #talk(1) ? #write(1) to the #tty(1) works.

inet suddenly disappeared, after `dhclient`, it restarts, but won't last long #networking #netplan #inetd

I've been obsessed with #C recently. Been reading lots of the #GNULibC manual, and just admiring what a feature
complete library it is (I always thaught you didn't get much of a stdlib with C for some odd reason, but of
course #Posix).

Came across the section on #inetd, so I decided to write my own as a learning experience. Obviously inetd today has
security issues, but it's a good way to learn about sockets, parsing config files, and a bunch of other posix stuff.
