Usability improvement fix ( issue #6 ). sshd.exe puts remote user and
host info on the console prompt. user@target $P$G is set as cmd.exe
PROMPT via environment variable.
Fix the reported problem #7. Remote directory set to remote user's home
directory like its is done on openssh on all platforms. Users can then
cd to "Documents" directory. Actual fix was to expand "." to user's home
directory so that pwd showed it correctly rather than just showing a
dot.
Pty mode code added so that sshd server can do remote echo, backspace
processing. etc and ssh.exe client does not have to do local echo. We
can enrich it in future for more features and allowing programs like
powershell to run interactive. Pty mode is central for interactive use
and will be built using Windows console instead of termios that
Linux/Unix uses.
Fixed this #3 problem ticket. We determine domain hostname which created
the authenticated token from the token and then pass it to
LoadUserProfile() Windows API which now correctly creates the user's
home directory name and profile folder.
Will fix problems like new hosts to be added to known_hosts file which
was failing when .ssh directory did not exist. Also default user's
public keys like id_rsa pairs are picked up properly from the user's
homdir/.ssh base.
Whether LF should be changed to CR-LF is determined by what the remote
sshd server wants. Sequences like ESC[20h is sent by sshd servers in pty
ANSI mode. Unix servers usually want LF and Windows servers CR-LF. Added
simple ANSI data check now for pty use in interactive mode. Need to
expand to simple ANSI engine in future for processing other ANSI
terminal attributes.
pty and tty support was not enabled or working in the code. Without pty
support, ssh client was very non functional - e.g. openssh linux server
prompt would not come through. Now ssh client works much better in
interactive mode ( uses pty).
NoMachine did not finish coding child process ending detection logic.
Added the needed code so that child process handle is added to the
handles that WaitForMultipleObjects() waits for in nomachine select()
implementation in socket.c. Otherwise select() would be stuck in
read/write dectection even when the process of interest has exited.
Fixed sftp-server put verb not working. Tested from out sftp client and
linux fedora openssh 6.9p1 sftp clients in transferring small and large
files using both get and put verbs.
sftp-server.exe code modified to work in Windows as NoMachine never
finished it to work. I/O handling to work as a subsystem and
openssh7.1p1 sshbuf_new() buffer system code had to be used. sshd_config
file need location of sftp subsystem to be specified.
ssh.exe client invoked underneath was not able to send password prompt
and read password from user as stdin and stdout handles were redirected
to sockets by sftp.exe ; stderr which is not redirected is used to show
prompt to users and data is read from console
