# Niver
## Features
### Web interface
* Login/register using a pseudo/password set
* Pages are lower than 10 KiB
* No JavaScript, no images, and CSS are optionnal
* Dark and light themes
* Free service running libre software
### Hypertext
* SFTP access
* HTTP and Gemini
* IPv4 and IPv6
* TLS 1.2 & 1.3
* DNS and Onion v3 (through Tor) access
* HTTP/1.1 and HTTP/2
* Let's Encrypt certificates for HTTP
* All HTTP security headers
### Nameserver
* DNSSEC (with NSEC3)
* NS, A, AAAA, TXT, and CAA records
### Registry
* Glue record
* DNSSEC delegation with any modern cypher
## Missing features
* No internationalized domain name support (you can only use a small subset of ASCII in your domain name)
* No BIND-style plaintext configuration (you need to fill a form for every record you add or remove)

# Niver system installation
Niver will use and need specific configuration for
* Knot DNS
* OpenSSH
* Nginx
* Tor
* Gmnisrv
* PHP-FPM
To do root-level actions, Niver will also use a privileged binary, written in Rust, called Maniver.
Niver has been deployed on the following distributions :
* Debian 10, using Nginx 1.14.2 and OpenSSH 7.9p1, and latest available version of Tor, Knot and gmnisrv using their official release channel.
* Arch Linux
To provide all features:
`# pacman -S tor knot openssh sudo nginx nginx-mod-headers-more certbot certbot-nginx php-fpm php-sqlite`
Some tools you might find usefull to manage a server:
`# pacman -S vnstat htop nload ufw vim man-db curl screen`
[Gemini](gemini.md)
[Maniver](maniver.md)
[OpenSSH](openssh.md)
[Nginx](nginx.md)

# Niver-PHP setup
Use pools configurations provided along this documentation.
To hide PHP presence, set in php.ini:
`expose_php = Off`
```
# useradd -U -r -s /usr/bin/nologin php-niver
# useradd -U -r -s /usr/bin/nologin php-errors
```
## Permission to manage system things as root
Once you've [set up Maniver](maniver.md):
```
# EDITOR=vim visudo
php-niver ALL=(root) NOPASSWD: /usr/local/bin/maniver
```
## Permission to manage Knot
To add knot as an additional group for user php-niver: `# usermod -aG knot php-niver`
New method:
```
# chmod -R 770 /var/lib/knot
# chown -R php-niver:knot /var/lib/knot
```

### SFTP setup
```
# groupadd ht
# echo "Ce compte n'est accessible qu'en SFTP, pas en SSH.
This account is only available over SFTP, not over SSH." > /etc/nologin.txt
# ssh-keygen -q -N "" -t ed25519 -f /etc/ssh/keys/ed25519
# ssh-keygen -q -N "" -t rsa -b 3072 -f /etc/ssh/keys/rsa-3072
# awk '$5 >= 3071' /etc/ssh/moduli > /etc/ssh/moduli.safe
# mv /etc/ssh/moduli.safe /etc/ssh/moduli
```
To get the ASCII art and SHA-256 fingerprints:
```
# ssh-keygen -vlf /etc/ssh/keys/ed25519.pub
# ssh-keygen -vlf /etc/ssh/keys/rsa-3072.pub
```
To generate SSHFP records:
```
# ssh-keygen -r sftp.niver.4.niv.re -f /etc/ssh/ed25519.pub
# ssh-keygen -r sftp.niver.4.niv.re -f /etc/ssh/rsa-3072.pub
```
Don't use the first record, which is SHA-1, use the second, which is SHA-256.
`SSHFP <pkey-algorithm> <hash-algorithm> <fingerprint>`
For `pkey-algorithm`:
* `1` means RSA
* `2` means DSA (must not be used)
* `3` means ECDSA (should not be used)
* `4` means Ed25519
For `hash-algorithm`:
* `1` means SHA-1 (must not be used)
* `2` means SHA-256
