Ssheven Save

ssheven

A minimal new SSH client for Mac OS 7/8/9.

Project status: as of 0.8.0 (see github releases), fairly secure and usable, but without a polished UX or all planned features. Versions prior to 1.0.0 should be considered alpha/beta quality.

system requirements

• CPU: Any PPC processor, or at least a 68030 (68040 strongly recommended).
• RAM: 2MB.
• Disk space: fits on a floppy.
• 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

• basic scp file transfer
• general code cleanup

1.0.0 (first "real" release)

• configurable terminal string
• configurable/auto-choosing SSH buffer size (improves feel for faster machines)
• nicer error presentation for more failure cases
• add known_hosts reset option
• read Apple HIG and clean up UI/UX
• all license info in an about box type thing
• finish and upload papercraft box, floppy sticker artwork, icon/logo svg

known problems

• drawing the screen is somewhat slow
• input latency feels high because redrawing the screen is slow (along with all the encryption, which is also slow)
• receiving a large amount of data may break the channel or cause lockups (e.g. cat /dev/zero)
• non-US keyboard input may or may not have issues

possible upcoming features

• more complete color support (currently uses the default Mac 8 color palette)
• 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.
