Waiver. To the greatest extent permitted by, but not in contravention 64 | of, applicable law, Affirmer hereby overtly, fully, permanently, 65 | irrevocably and unconditionally waives, abandons, and surrenders all of 66 | Affirmer's Copyright and Related Rights and associated claims and causes 67 | of action, whether now known or unknown (including existing as well as 68 | future claims and causes of action), in the Work (i) in all territories 69 | worldwide, (ii) for the maximum duration provided by applicable law or 70 | treaty (including future time extensions), (iii) in any current or future 71 | medium and for any number of copies, and (iv) for any purpose whatsoever, 72 | including without limitation commercial, advertising or promotional 73 | purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each 74 | member of the public at large and to the detriment of Affirmer's heirs and 75 | successors, fully intending that such Waiver shall not be subject to 76 | revocation, rescission, cancellation, termination, or any other legal or 77 | equitable action to disrupt the quiet enjoyment of the Work by the public 78 | as contemplated by Affirmer's express Statement of Purpose. 79 | 80 | 3. Public License Fallback. Should any part of the Waiver for any reason 81 | be judged legally invalid or ineffective under applicable law, then the 82 | Waiver shall be preserved to the maximum extent permitted taking into 83 | account Affirmer's express Statement of Purpose. In addition, to the 84 | extent the Waiver is so judged Affirmer hereby grants to each affected 85 | person a royalty-free, non transferable, non sublicensable, non exclusive, 86 | irrevocable and unconditional license to exercise Affirmer's Copyright and 87 | Related Rights in the Work (i) in all territories worldwide, (ii) for the 88 | maximum duration provided by applicable law or treaty (including future 89 | time extensions), (iii) in any current or future medium and for any number 90 | of copies, and (iv) for any purpose whatsoever, including without 91 | limitation commercial, advertising or promotional purposes (the 92 | "License"). The License shall be deemed effective as of the date CC0 was 93 | applied by Affirmer to the Work. Should any part of the License for any 94 | reason be judged legally invalid or ineffective under applicable law, such 95 | partial invalidity or ineffectiveness shall not invalidate the remainder 96 | of the License, and in such case Affirmer hereby affirms that he or she 97 | will not (i) exercise any of his or her remaining Copyright and Related 98 | Rights in the Work or (ii) assert any associated claims and causes of 99 | action with respect to the Work, in either case contrary to Affirmer's 100 | express Statement of Purpose. 101 | 102 | 4.

NAT traversal powered by Nostr. 3 | 4 | ## How to Setup 5 | 6 | On your computer: 7 | 8 | ```bash 9 | ## Clone the repository and navigate inside. 10 | git clone 11 | cd nostr-terminal 12 | 13 | ## Install package dependencies. 14 | yarn install || npm install 15 | 16 | ## Start the terminal server using a package manager. 17 | yarn start || npm start 18 | 19 | ## You can also start the server directly, and provide arguments. 20 | ./nostrTerm.js 21 | 22 | ## If you want to specify your own defaults, 23 | ## create an .env file with the following: 24 | ADDRESS= 25 | SECRET= 26 | ``` 27 | 28 | The app will give you a base64 encoded connection string to copy/paste into the browser client. This string includes the relay url and connection secret, so keep it safe! 29 | 30 | If you do not provide a secret, the server will generate a random secret for you. This is the safest option! 31 | 32 | On your browser: 33 | ```ini 34 | ## Navigate to the browser client (hosted on github): 35 | https://cmdruid.github.io/nostr-terminal/web 36 | 37 | ## Or host your own web client! The files are here: 38 | nostr-terminal/web 39 | ``` 40 | 41 | ## How to Use 42 | 43 | The browser client will connect to your terminal server, using the same user account running the server. Be careful running this app as a sudo or administartor user! 44 | 45 | There are two modes for the terminal: `buff mode` or `live mode`. You can toggle modes by clicking the `[ mode ]` button located near the top-right of the terminal window. 46 | 47 | **buff mode**: 48 | Most keyboard input is buffered locally, then sent to your machine when you press enter. This is the fastest mode, plus it prevents flooding the relay with every keystroke. Certain features do not work in this mode, such as Up/Down (for scrolling command history) and Tab (for auto-completion). I'm looking to implement them in the future! 49 | 50 | **live mode**: 51 | All keyboard input is streamed in real-time. This is nessecary when using a text editor (like vim or nano), but it will flood the relay with traffic. This app uses ephemeral events, so we are flooding in the most friendly way possible. However not all relays may handle this traffic properly, so please use this mode wisely and consider running your own relay if you plan to use it frequently. 52 | 53 | ## Tips on Usagefas 54 | 55 | ```bash 56 | ## Start the terminal server as a background process, 57 | ## and save the connection string to a local file. 58 | ./nodeTerm.mjs > secrets.txt & 59 | cat secrets.txt 60 | ``` 61 | 62 | ## Disclaimer 63 | 64 | This is a demo project that opens a remote terminal connection into your machine. The connection is end-to-end encrypted with a secret, and uses a modern cryptography library (webcrypto) with best-practices. That being said, please review the code being used (NostrEmitter is just 500 lines), and take your own precautions! 65 | 66 | ## Known Issues 67 | 68 | If you open a text editor (or any TUI application) while using `buff mode`, the screen may not draw properly. Switch to `live mode` before opening the application. 69 | 70 | If you switch to `live mode` while you still have characters in the buffer, they will not be sent to the server properly. 71 | 72 | If you lose / close the connection while inside an editor (or any TUI application), the screen will not re-draw the application properly when you reconnect. I'm currently looking for elegant ways to fix this, and suggestions are welcome! 73 | 74 | ## Bugs / Questions 75 | 76 | Please feel free to post any bugs or questions on the issues page! 77 | 78 | ## Contributions 79 | 80 | Anyone may contribute!

This demo uses node-pty to access the terminal, xtermjs for
the console, and nostr emitter as the transport layer.

42 |

Check out the github readme on how to use the [ buff ] and [ live ] modes.

43 |

Sometimes the unpkg.com CDN fails to serve the xtermjs library. If the page
appears broken upon loading, try refreshing the page.
