rust-motd Setup

#rust  #motd  #systemd-timer 

2022-03-04 update:

gdm 用户最好不要启用 motd. 否则在登录界面会卡很久才进去.

有办法可以禁用这一行为, see https://bbs.archlinux.org/viewtopic.php?pid=1684018#p1684018

moving the following line:

session    optional   pam_motd.so          motd=/etc/motd

from /etc/pam.d/system-login to /etc/pam.d/sshd.

The result is that the motd is no longer displayed in gdm, but it’s still displayed when logging in through ssh.

Beautiful, useful, configurable MOTD generation with zero runtime dependencies

如果显示 hostname 时想使用 figlet 的话需要安装一下:

paru -S figlet
