1 # Decentralized Remotely Accessed Memory 2 3 Ever joked about [downloading more RAM](https://downloadmoreram.com/)? 🤣 WELL NOW YOU CAN MOTHER FUCKER! 4 5 **Here's the deal:** we use a [tmpfs](https://en.wikipedia.org/wiki/Tmpfs) on the donor machine to pretend a chunk of its RAM is a hard drive. Then, we get fancy with [NFS](https://en.wikipedia.org/wiki/Network_File_System) to share this faux-drive over the network 🌐. On the recipient's side, we mount this networked RAM-drive and set up a swap file. 6 7 Go insane with it & donate RAM from multiple machines...decentralize the RAM of a single server all over the planet! Latency is the devil 😈 LOL 8 9 ## The make-it-happen Magic 10 #### Setup RAM Donator 11 1. Create an entry in `/etc/fstab` to create the RAM partition: 12 13 `tmpfs /mnt/ramote_send tmpfs nodev,nosuid,noexec,nodiratime,size=1G 0 0` 14 15 **Note:** Change `1G` to the amount of RAM you want to donate. 16 17 2. Create the RAM partition directory & mount it: 18 19 ```bash 20 mkdir -p /mnt/ramote_send 21 mount /mnt/ramote_send 22 ``` 23 24 3. Download & install an NFS server daemon of your choice: 25 26 ```bash 27 apt-get install nfs-kernel-server 28 ``` 29 30 4. Configure & start the NFS server: 31 - Edit your `/etc/exports` file: 32 33 `/mnt/ramote_send <client-ip>(rw,sync,no_root_squash,no_subtree_check)` 34 35 - Start & enable the service: 36 37 ```bash 38 systemctl start nfs-kernel-server 39 systemctl enable nfs-kernel-server 40 ``` 41 42 --- 43 44 #### Setup RAM Receiver 45 1. Create a directory & mount the NFS: 46 47 ```bash 48 mkdir -p /mnt/ramote_recv 49 mount <nfs-server-ip>:/mnt/ramote_send /mnt/ramote_recv 50 ``` 51 52 2. Create & enable a swap file inside the NFS directory: 53 ```bash 54 dd if=/dev/zero of=/mnt/ramote_recv/swapfile bs=1M count=1024 55 chmod 600 /mnt/ramote_recv/swapfile 56 mkswap /mnt/ramote_recv/swapfile 57 swapon /mnt/ramote_recv/swapfile 58 ``` 59 60 **Note:** Change the swap file size according to what you allocated on the donator. 61 62 3. Create an entry in `/etc/fstab` to for the NFS mount & the swap file: 63 64 ``` 65 <nfs-server-ip>:/mnt/ramote_send /mnt/ramote_recv nfs defaults 0 0 66 /mnt/ramote_recv/swapfile swap swap defaults 0 0 67 ``` 68 69 You can do this across various machines & use multiple swap files for decentralize even more. 70 71 ___ 72 73 ###### Mirrors for this repository: [acid.vegas](https://git.acid.vegas/dram) • [SuperNETs](https://git.supernets.org/acidvegas/dram) • [GitHub](https://github.com/acidvegas/dram) • [GitLab](https://gitlab.com/acidvegas/dram) • [Codeberg](https://codeberg.org/acidvegas/dram)
