A modern SSH client for Mac OS 7/8/9.
Project status: as of 0.8.0 (see github releases), a functional (but not completely secure) SSH client with color terminal emulation, able to login via key or password. See roadmap below for upcoming work (i.e., things that aren't done yet).
- CPU: Any PPC processor, or at least a 25 MHz 68040/68LC040. Presently, all 68030 and 68020 CPUs are too slow.
- RAM: 2MB.
- Disk space: 1MB for the fat binary.
- System 7.5 or later, earlier System 7 versions might be possible with the Thread Manager extension installed.
- Open Transport networking required, version 1.1.1 or later recommended.
0.9.0
- clean up network ops (write fn, read safety, don't allow send until connected, quit while connected mess)
- clean up preferences loading/saving, include key stuff,
known_hostsreset option - build/packaging scripts
- general ssheven code cleanup
- text selection + copy
1.0.0 (first "real" release)
- nicer error presentation for more failure cases
- read Apple HIG and obsessively optimize placement of all GUI elements
- license info in an about box type thing
- finish and upload papercraft box, floppy sticker artwork, icon/logo svg
known bugs
- initial key exchange is too slow for 68030 and 68020 systems (improve
mbedtls_mpi_exp_modand maybe the assembly BN code?) - input latency feels high? related to draw speed/frequency? (maybe try to use an "offscreen graphics world" framebuffer? big refactor)
- receiving a large amount of data breaks the channel (e.g.
cat /dev/zero) - preference file loading has issues, especially with the key paths
- hook scrolling into vterm to reduce redraws/blanking
possible upcoming features
- font face and size options
- scp file transfer
- more complete color support (will need to use color quickdraw, currently uses an 8-color hack for traditional quickdraw)
- keyboard-interactive authentication
Uses Retro68 and cmake.
Requires mbedtls, libssh2, and libvterm, see my (cy384's) ports of those libraries for details. Note that you need to build/install each for both platforms (m68k and PPC).
mkdir build && cd buildcmake .. -DCMAKE_TOOLCHAIN_FILE=/your/path/to/Retro68-build/toolchain/powerpc-apple-macos/cmake/retroppc.toolchain.cmakeorcmake .. -DCMAKE_TOOLCHAIN_FILE=/your/path/to/Retro68-build/toolchain/m68k-apple-macos/cmake/retro68.toolchain.cmakemake
Use Rez to build the fat binary: join the data fork from the PPC version and the resource fork from the m68k version.
I have some build scripts that I'll clean up and publish with the 1.0.0 release.
note to self: binary resources can be extracted in MPW via: DeRez "Macintosh HD:whatever" -skip "'CODE'" -skip "'DATA'" -skip "'RELA'" -skip "'SIZE'" etc., this is especially useful for icons
