100 MUD Hosting resources for MUD players

Utilize CAX11 instances for high-performance, low-cost hosting. ARM architecture is more than sufficient for C-based MUDs like ROM or CircleMUD and offers superior price-to-performance ratios.

Leverage the 4 OCPU and 24GB RAM allowance for resource-heavy Java or Python-based MUD engines (like Evennia or CoffeeMUD) without incurring monthly costs.

Install 'libc6-i386' and 'lib32stdc++6' on 64-bit Debian/Ubuntu systems to run older 32-bit MUD binaries compiled in the late 90s.

Containerize the MUD codebase using a build stage for GCC/Make and a minimal Alpine Linux run stage to reduce the attack surface and image size.

Configure at least 2GB of swap space on 1GB RAM VPS instances to prevent the OOM (Out of Memory) killer from terminating the MUD process during heavy compiles or world resets.

Compile the MUD with the '-static' flag to bundle all libraries into the binary, ensuring portability across different Linux distributions without library version conflicts.

Use Tmux sessions to keep the MUD running while allowing admins to detach and reattach to the live console for real-time debugging.

Select high-clock-speed instances for MUDs with complex pathfinding or heavy scripting engines to minimize tick-latency in high-population areas.

Enable ZRAM on low-memory servers to compress memory pages, effectively doubling usable RAM for MUDs with massive world files and high object counts.

Compile with '-march=native' on the host machine to leverage specific CPU instructions of the VPS hardware, improving execution speed for heavy loops.

Create a .service file with 'Restart=always' and 'RestartSec=5' to ensure the MUD automatically reboots following a crash or server restart.

Schedule a cron job using Rclone to sync the 'player/' and 'lib/area/' directories to encrypted S3-compatible storage like Backblaze B2.

Configure /etc/logrotate.d/mud to compress and rotate the 'log/stderr' and 'log/syslog' files daily, preventing disk exhaustion from recursive bug loops.

Set up external monitoring on the specific telnet port (e.g., 4000) to receive instant alerts via mobile push or Discord webhook if the game stops responding.

Use a private GitHub/GitLab repository to push code updates, using a 'post-receive' hook on the server to automatically recompile the binary.

Write a Bash script that uses 'nc' (netcat) to probe the game port; if it fails to connect, it triggers a kill -9 and a fresh start of the binary.

For MUDs using MariaDB/MySQL for player data, use 'mysqldump' with the '--single-transaction' flag in a nightly cron job to ensure data consistency.

Host a duplicate 'test' instance on a secondary port (e.g., 4001) to allow builders to verify area changes before merging into the production directory.

Monitor 'iowait' values; high disk latency on a shared VPS can cause 'ghost lag' in MUDs that frequently write to player files during saves.

Enable weekly provider-level snapshots (DigitalOcean/Linode) to provide a full-system recovery point in the event of a botched OS upgrade.

Never run the MUD process as root. Create a 'mud' user with restricted shell access to contain potential exploits within the game directory.

Disable password-based SSH login in /etc/ssh/sshd_config to prevent brute-force attacks against admin accounts.

Configure Fail2Ban to monitor the MUD's log files for rapid connection attempts, automatically banning the IP at the firewall level.

Use Uncomplicated Firewall (UFW) to deny all incoming traffic except for the SSH port and the specific MUD game port.

Replace legacy MD5 or plaintext password functions in the C source code with a modern Bcrypt library to protect player credentials.

Set up Stunnel to wrap the telnet port in TLS, allowing players using modern clients (like Mudlet) to connect via a secure, encrypted tunnel.

Restrict access to web-based admin panels or database tools to a private WireGuard VPN IP range, keeping them off the public internet.

Run the MUD process within a chroot environment to ensure that even a remote code execution exploit cannot access /etc/ or other system files.

Configure the Linux Audit Daemon to log any modifications to the 'src/' directory or 'bin/' folder to detect unauthorized code injections.

Enable the 'unattended-upgrades' package to ensure that security patches for the Linux kernel and SSH are applied automatically without admin intervention.
