AlternC is an open-source web hosting control panel and shared hosting management platform for Linux servers, primarily designed for Debian-based systems. It provides a lightweight alternative to commercial hosting panels like cPanel or Plesk. It was originally developed by French hosting and free-software communities to provide a fully open-source hosting environment for multi-user web hosting. What AlternC Does AlternC allows a server administrator to manage: Websites and virtual hosts Domains and DNS zones Email accounts FTP accounts MySQL/MariaDB databases Webmail Shared hosting users Disk quotas SSL certificates It essentially turns a Debian VPS or dedicated server into a multi-tenant hosting platform. Core Components AlternC typically integrates with: Service Purpose Apache Web server MariaDB/MySQL Databases Postfix Mail sending Dovecot IMAP/POP3 BIND9 DNS hosting PHP Dynamic websites SpamAssassin Spam filtering ClamAV Antivirus scanning Typical Use Cases AlternC is commonly used for: Shared hosting environments Small hosting providers Educational hosting platforms Non-profit hosting projects Self-hosted web/mail servers Lightweight alternative to commercial panels Key Features Multi-user Hosting Each user can manage: Their own domains Mailboxes FTP accounts Databases Web files Without root access.

AlternC installs and manages its own web, mail, DNS, database, and hosting services. Point DNS to the VPS Before installing, create these DNS records at your DNS provider: panel.example.com. A YOUR_SERVER_IP ns1.example.com. A YOUR_SERVER_IP mail.example.com. A YOUR_SERVER_IP Optional but recommended: example.com. MX 10 mail.example.com. If AlternC will manage DNS for hosted domains, you will also want nameserver glue records at your registrar, for example: ns1.example.com → YOUR_SERVER_IP Log in as root ssh root@YOUR_SERVER_IP Update the server: apt update apt upgrade -y reboot Reconnect after reboot: ssh root@YOUR_SERVER_IP Set the hostname Replace the hostname with your real panel hostname: hostnamectl set-hostname panel.example.com Edit /etc/hosts: nano /etc/hosts Use something like: 127.0.0.1 localhost YOUR_SERVER_IP panel.example.com panel Verify: hostname -f Expected result: panel.example.com Install basic tools apt install -y curl wget gnupg ca-certificates apt-transport-https lsb-release sudo nano Verify Debian version cat /etc/os-release You want: VERSION_CODENAMEbookworm AlternC’s current official repository instructions specifically reference Bullseye and Bookworm, with Bookworm actively tested. Check APT sources Make sure your Debian sources are valid. cat /etc/apt/sources.list A basic Debian 12 Bookworm setup should look similar to: deb http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware deb http://deb.debian.org/debian bookworm-updates main contrib non-free non-free-firmware deb http://security.debian.org/debian-security bookworm-security main contrib non-free non-free-firmware Then update: apt update Install AlternC The official AlternC Debian repository currently lists the Bookworm install process as: apt update apt install alternc alternc.install Run: apt install -y alternc During installation, Debian may ask package configuration questions. Answer according to your server details. Run the AlternC installer After packages are installed, run: alternc.install You will be asked several configuration questions. Typical values: Public IP address: YOUR_SERVER_IP Server hostname: panel.example.com Primary domain: example.com DNS hostname: ns1.example.com Mail hostname: mail.example.com Use your actual domain and hostname. Reboot after installation reboot Reconnect: ssh root@YOUR_SERVER_IP Check service status Run: systemctl status apache2 --no-pager systemctl status postfix --no-pager systemctl status dovecot --no-pager systemctl status mariadb --no-pager systemctl status bind9 --no-pager Also check listening ports: ss -tulpn You should commonly see services listening on ports such as: 80 HTTP 443 HTTPS 25 SMTP 53 DNS 110 POP3 143 IMAP 587 SMTP submission 993 IMAPS 3306 MariaDB local/private use Access the AlternC panel Open: http://panel.example.com/ or: http://YOUR_SERVER_IP/ If HTTPS is not yet configured, start with HTTP first. Secure the panel with HTTPS If Certbot is available on your Debian install: apt install -y certbot python3-certbot-apache Then request a certificate: certbot --apache -d panel.example.com Follow the prompts. Test renewal: certbot renew --dry-run Open firewall ports If using UFW: apt install -y ufw ufw allow OpenSSH ufw allow 80/tcp ufw allow 443/tcp ufw allow 25/tcp ufw allow 587/tcp ufw allow 993/tcp ufw allow 53/tcp ufw allow 53/udp ufw enable ufw status Optional mail ports: ufw allow 110/tcp ufw allow 143/tcp ufw allow 465/tcp ufw allow 995/tcp Configure reverse DNS Set PTR/rDNS for your VPS IP through your VPS provider. Recommended PTR: YOUR_SERVER_IP → mail.example.com Then verify: dig -x YOUR_SERVER_IP +short Configure SPF, DKIM, and DMARC At minimum, add SPF: example.com. TXT "vspf1 mx a ip4:YOUR_SERVER_IP -all" Add DMARC: _dmarc.example.com. TXT "vDMARC1; pquarantine; ruamailto:postmaster@example.com" DKIM depends on your AlternC/Postfix configuration. Check whether DKIM tooling is installed: dpkg -l | grep -Ei 'dkim|opendkim' Create your first AlternC account From the AlternC web interface: Log in as the administrator. Create a new member/user. Assign disk quota. Add a domain. Create mailbox accounts. Create databases if needed. Upload website files through FTP/SFTP or the AlternC file tools. Test website hosting Create a test file: echo "AlternC is working" > /var/www/html/test.html Then visit: http://panel.example.com/test.html For hosted domains, add the domain inside AlternC, point DNS to the server, and test: curl -I http://example.com Test mail delivery Install mail tools: apt install -y mailutils Send a test email: echo "AlternC mail test" | mail -s "Test email from AlternC VPS" you@example.net Watch logs: tail -f /var/log/mail.log Common troubleshooting Package not found Run: apt update apt-cache policy alternc Confirm you are on Debian Bookworm: cat /etc/os-release Hostname problem Check: hostname -f cat /etc/hosts Apache not starting apachectl configtest journalctl -xeu apache2 Mail not sending systemctl status postfix --no-pager tail -100 /var/log/mail.log DNS not answering systemctl status bind9 --no-pager dig @127.0.0.1 example.com Maintenance commands Update Debian and AlternC packages: apt update apt upgrade -y Check failed services: systemctl --failed Check logs: journalctl -p err -xb Check disk usage: df -h du -sh /var/* 2>/dev/null Recommended production hardening Install Fail2ban: apt install -y fail2ban systemctl enable --now fail2ban Disable root password login: nano /etc/ssh/sshd_config Set: PermitRootLogin prohibit-password PasswordAuthentication no Restart SSH: systemctl restart ssh Keep regular backups of: /etc /var/lib/mysql /var/www /var/alternc /home Quick install summary apt update apt upgrade -y hostnamectl set-hostname panel.example.com apt install -y curl wget gnupg ca-certificates sudo nano apt update apt install -y alternc alternc.install reboot AlternC should now be installed and ready at: http://panel.example.com/ Conclusion You now know how to install AlternC on Debian VPS.
