A modern SSH client for Mac OS 7/8/9

ssheven

A modern SSH client for Mac OS 7/8/9.

Project status: as of 0.8.0 (see github releases), a functional SSH client, able to connect via key or password. Versions prior to 1.0.0 are alpha/beta quality.

system requirements

• 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 7.1 or later. Versions below 7.5 require the Thread Manager extension.
• Open Transport networking required, latest version possible highly recommended.

roadmap

0.9.0

• general ssheven code cleanup
• select words on double click
• font face and size options

1.0.0 (first "real" release)

• nicer error presentation for more failure cases
• add known_hosts reset option
• read Apple HIG and clean up UI/UX
• license info in an about box type thing
• finish and upload papercraft box, floppy sticker artwork, icon/logo svg
• configurable terminal string

known bugs

• initial key exchange is too slow for 68030 machines (improve mbedtls_mpi_exp_mod and BN assembly) (needs 5x speed improvement for 68030)
• input latency feels high because redrawing the screen is slow
• receiving a large amount of data breaks the channel (e.g. cat /dev/zero)
• excessive redraws/flicker while selecting
• non-US keyboard input has issues
• custom colors are a little wonky

possible upcoming features

• scp file transfer
• more complete color support (currently uses an 8-color hack)
• keyboard-interactive authentication

build

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).

To build a fat binary, edit build-ssheven.bash with the path to your Retro68 build, and then run it.
