communicator48-modern

Launch Netscape Communicator 4.8 on a modern Linux system in a self-contained environment.

This repo does not include the Communicator binary. You must supply:

• communicator-v48-us.x86-unknown-linux2.2.tar.gz

Put that tarball in the repo root, then run:

./setup.sh
./run-communicator.sh

If you want to use a different archive path, set COMMUNICATOR_ARCHIVE when running setup.sh.

What it does

• extracts the supplied Communicator archive into app/
• downloads old Debian X11, glibc, libstdc++, and bitmap font packages into compat/
• stages a local 32-bit runtime under compat/glibc, compat/lib, and compat/x11
• patches a pair of startup probes in the Communicator binary that modern X servers can reject
• launches Communicator inside bwrap with a local state directory under state/
• temporarily adds bundled misc, 75dpi, and 100dpi bitmap font paths before startup and removes them again on exit

Requirements

• Linux with 32-bit x86 execution enabled
• a working X11 display or Xwayland session
• bash, curl, ar, find, tar, gzip
• bwrap (bubblewrap) to launch the isolated runtime
• optional: xset to register the bundled bitmap fonts with the X server
  • Common package names: xorg-xset on Arch, x11-xserver-utils on Debian/Ubuntu, xset on Fedora.

Notes

• This is a compatibility hack, not a period-correct environment.
• Modern HTTPS is still mostly out of scope. Plain HTTP and very simple sites are the realistic target.
• The launcher writes local hosts and nsswitch.conf files under compat/etc/ for the bubblewrap environment.
• MOZILLA_NO_ASYNC_DNS=True is enabled by default. Override it if you specifically want to test Communicator's built-in async DNS behavior.

Compatibility proxies

If you want to reach more of the modern web, run a compatibility proxy on another machine or locally and point Communicator at it as an HTTP proxy.
