By way of the QJ.Net Forums, homebrew coder Zx-81 has announced that PSPSSH is now at version 1.0.3. This homebrew application is "a protocol for remotely using the command line on a system, primarily Linux systems," as freyyr890 explained regarding PSPSSH's previous version.

This allows your PSP to issue command lines to your Linux, Unix, or Windows systems (provided they're running on an SSH server) so long as you have an internet connection.

PSPSSH is Zx-81's PSP port of the Dropbear SSH2 Server and Client by Matt Johnston, with PSPSSH specifically a port of client version 0.48.1. Moving on to version 1.0.3's changelog:

New Danzeff keyboard layout (alt keys are now available)
New option to save the vt100 screen as a text file.
New login menu (more friendly, and with new options)
Improve vt100 emulation (for example, the nano editor works fine now)
As Matt Johnston advised me, I've added a new initial random seed generation, using keystroke latency (you have now to press psp keys randomly, the first time you run PSPSSH).
Bug fix in random number generator
Bug fix in key send function
Bug fix in vt100 emulator

Full installation instructions, usage details, and changelog lists are available in the download pack - make sure to go over the notes first. There is also The PSP release thread over at the QJ.Net Forums, which should provide for additional app-related discussions. Enjoy your download!
