# Essential software for new systems
|
|
|
|
This is just a quick personal reference so I don't have to guess.

## Security
|
|
|
|
- `microcode` - propietary, but otherwise CPU holes are going to be gaping open. Refer to `tail -n +1 /sys/devices/system/cpu/vulnerabilities/*`
|
|
- Debian calls this as `amd64-microcode` or `intel-microcode`
|
|
- `ufw` for Deb-based or `firewalld` on Fedora
|
|
- `sshguard` for mitigating shared systems where others refuse to use keys
|
|
- `needrestart` for knowing when updates actually require services to be restarted or a kernel upgrade happens and requires reboot
|
|
- `molly-guard` so you won't accidentally `reboot` or `poweroff` production rather than local machine.
|
|
- `apt-listchanges` changelogs are worth knowing when updating.
|
|
- `apt-listbugs` known bugs are especially nice when performing bigger updates.
|
|
- `chrony` - security demands the time to be correct, Chrony supports NTS and is proper NTP server instead of just SNTP like systemd-timesyncd.
|
|
- alternatively configure `systemd-timesyncd`
|
|
- `unbound` - my choice for both DNSSEC validating and DNS-over-TLS, even if I had it connect to upstream dns\[crypt\]proxy
|
|
- alternatively configure `systemd-resolved`. Simultaneously `systemd-networkd` may be a good idea.
|
|
- `unattended-upgrades` or `dnf-automatic` so security updates are at least downloaded if not even directly installed (see configuration and systemd units!)
|
|
- if `dnf-automatic`, consider `sudo systemctl enable dnf-automatic-install.{timer,service}`
|
|
or at least `sudo systemctl enable dnf-automatic-download.{timer,service}`
|
|
|
|
## Usability
|
|
|
|
- `nvim git tmux zsh` - good luck without these
|
|
- if cryptographic operations are taking ages, consider something like `haveged`. It's controversial, so if there are no issues, don't install a random number generator.
|
|
- userspace oom killer, may avoid frozen systems, much more pleasant than actually having to deal with a frozen system.
|
|
- `earlyoom`
|
|
- remember to `sudo systemctl enable --now earlyoom`
|
|
- `systemd-oomd`
|
|
- remember to `sudo systemctl enable --now systemd-oomd`
|
|
- `zram-tools` - small compressed swap in RAM
|
|
- Remember to check configs! Fedora: `/etc/zram.conf`
|
|
- `sudo systemctl enable --now zramswap.service zram-swap.service`
|
|
- `thermald` for additional help keeping system cool, especially intel
|
|
- `sudo systemctl enable --now thermald`
|
|
- `vnstat` - help for observing bandwidth usage
|
|
- `yggdrasil` - essential for getting through Carrier Grade NAT whether there is IPv6 or not. Also gives static internal IPv6 reducing need for dynamic DNS.
|
|
- `tlp` - for laptop power management, especially ThinkPad.
|
|
- `sudo tlp-stat | less`
|
|
- `sudo systemctl enable --now tlp`
|
|
|
|
## Offtopic system configuration
|
|
|
|
This is just too close to not mention here (and was besides in my planning issue):
|
|
|
|
### Debian-based
|
|
|
|
- `sudo dpkg-reconfigure console-setup`
|
|
- ensure UTF-8 and select Terminus
|
|
- `sudo dpkg-reconfigure keyboard-configuration`
|
|
- compose key
|
|
|
|
### SSD
|
|
|
|
- `sudo systemctl enable --now fstrim.timer`
|
|
- check that `/etc/fstab` has `noatime` so every file access isn't written to the disk. BTRFS filesystems should also have `ssd` flag.
