ReceiveScpConfirmation() takes a WS_EXTDATA off ScpStreamRead()'s return, the rule ssh.h now states for reading an event. FlushQueuedSend() samples the owed write with the session still locked, since the peer reader thread writes ssh->error too, and reports a send that failed there over the event it rode in on. - A pass that delivers stderr while its flush short-writes returns WS_EXTDATA with WS_WANT_WRITE in ssh->error, so the confirmation read aborted the transfer with the stderr undrained. - wolfSSH_stream_read() on the reader thread clears ssh->error with this thread's packet still queued, which ended the flush early and reported it a success. - An event return with a hard send error latched collapsed to WS_SUCCESS, telling the caller a queued packet reached a socket that was gone. |

WOLFSSH CLIENT
The wolfSSH client will connect to a server and try to open a terminal. It'll
default the username to your current username, and it will try to use your
ecdsa private key to authenticate. The key file path is hard coded to
$HOME/.ssh/id_ecdsa. It is currently far enough along I can use it. The
private keys are the ones produced by the OpenSSL command line tool, not the
ssh-keygen tool.
Phase 2 is going to bring reading the config files /etc/ssh/ssh_config and
$HOME/.ssh/config. It will handle OpenSSH style modern keys. It will also
have support for SSH-AGENT and forwarding.
Every session, terminal or command, runs its I/O on threads, so the client
needs a threaded wolfSSL. Configuring --enable-sshclient against a
single-threaded wolfSSL is an error, and --enable-all leaves the client out
rather than failing.
Command Line Options
-E logfile : Append the log to this file instead of stderr, and turn
logging on. The log is empty unless the library has
logging compiled in, with `--enable-debug` or
`--enable-sshd`.
-G : Print out the configuration as used.
-l login_name : Overrides the login name specified in the destination.
-p port : Overrides the destination port number.
-V : Print out the version.
The destination option is the only required option. It can be in the two following formats:
[user@]hostname
ssh://[user@]hostname[:port]
Anything after the destination is taken as a command to run on the server. With no command, the client opens an interactive terminal session.
The default value for user is the current user's login name. The default value for port is 22.
