bunkchat 🏰

bunkchat is ultra-simple, local-only chat for tilde servers written in posix sh

install

git clone https://git.bunk.computer/bunk/bunkchat.git && \
cd ./bunkchat && \
sudo ./install.sh

usage

bunkchat is comprised of three separate programs

  1. proclaim - post in chat
  2. heed - read current chat
  3. scry - read old chat

run proclaim and heed in adjacent terminals for best ux

security

hopefully!

  • the chat log is append only, but anyone can append anything to it
  • proclaim only accepts user input with read -r, which does not expand variables, and appends to the chat log with echo "$userinput" >> $chatlog
  • heed only does tail -f on the chat log
  • scry only opens the chat log with less
  • no one has execute permissions on the chat log

if you find a security issue, please contact us

notes

if your file system does not support setting append only permissions with chattr +a, install.sh will fail

bunkchat should work on all standard linuxes. not tested on bsd
