Previously, SSH authentication banners were displayed by calling the
ordinary seat_output function, and passing it a special value in the
SeatOutputType enumeration indicating an auth banner.
The awkwardness of this was already showing a little in SshProxy's
implementation of seat_output, where it had to check for that special
value and do totally different things for SEAT_OUTPUT_AUTH_BANNER and
everything else. Further work in that area is going to make it more
and more awkward if I keep the two output systems unified.
So let's split them up. Now, Seat has separate output() and banner()
methods, which each implementation can override differently if it
wants to.
All the 'end user' Seat implementations use the centralised
implementation function nullseat_banner_to_stderr(), which turns
banner text straight back into SEAT_OUTPUT_STDERR and passes it on to
seat_output. So I didn't have to tediously implement a boring version
of this function in GTK, Windows GUI, consoles, file transfer etc.
This is the README for PuTTY, a free Windows and Unix Telnet and SSH
client.
PuTTY is built using CMake <https://cmake.org/>. To compile in the
simplest way (on any of Linux, Windows or Mac), run these commands in
the source directory:
cmake .
cmake --build .
Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory using `doc/Makefile'. If you aren't using one of our
source snapshots, you'll need to do this yourself. Halibut can be
found at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
The PuTTY home web site is

If you want to send bug reports or feature requests, please read the
Feedback section of the web site before doing so. Sending one-line
reports saying `it doesn't work' will waste your time as much as
ours.
