cputty 1.0.0

cputty is a cluster-SSH tool based on PuTTY 0.85, in the style of the classic Solaris cssh: it opens one PuTTY terminal window per host plus a console window, and keystrokes typed into the console go to every ticked session.

cputty -l user web1 web2 web3

What's in 1.0.0

• cputty for Linux (GTK) and Windows: console with per-host checkboxes (All / None / Invert), an echo field showing what you type (auto-clears after 15 s, with a Hide typed text option for passwords), and a confirmation before closing live sessions. Typing into a terminal window affects only that session.
• SSH only: Telnet, Rlogin, SUPDUP, Raw, serial-line support and the "Telnet" proxy type have been removed from all tools. Saved sessions that used the Telnet proxy type refuse to connect instead of silently bypassing the proxy.
• Faster: terminal output processing is about 4x faster than an unoptimised build, with smaller binaries. The crypto code is built as upstream ships it and was checked with PuTTY's side-channel test (testsc).

Notes

• The Linux binaries and packages were built on Debian 13 (glibc 2.41, GTK 3) and need an equally recent distribution.
• The Windows executables are not code-signed, so Windows SmartScreen may warn on first run. The Windows build has been tested under Wine, not yet on real Windows.
• This is a modified version of PuTTY and is not supported by the PuTTY developers. Licence: MIT (see LICENCE).
