-termchat Do the UltraVNC chat in the terminal vncviewer is in

-unixpw str Useful for logging into x11vnc in -unixpw mode. "str" is a
string that allows many ways to enter the Unix Username
and Unix Password. These characters: username, newline,
password, newline are sent to the VNC server after any VNC
authentication has taken place. Under x11vnc they are
used for the -unixpw login. Other VNC servers could do
something similar.
You can also indicate "str" via the environment
variable SSVNC_UNIXPW.
Note that the Escape key is actually sent first to tell
x11vnc to not echo the Unix Username back to the VNC
viewer. Set SSVNC_UNIXPW_NOESC=1 to override this.
If str is ".", then you are prompted at the command line
for the username and password in the normal way. If str is
"-" the stdin is read via getpass(3) for username@password.
Otherwise if str is a file, it is opened and the first line
read is taken as the Unix username and the 2nd as the
password. If str prefixed by "rm:" the file is removed
after reading. Otherwise, if str has a "@" character,
it is taken as username@password. Otherwise, the program
exits with an error. Got all that?
