As far as I know, if the application crashed and we're talking here about a
Windows machine, then someone needs to physically access it to reboot it.  If
it is a Linux OS with MMF running in Vmware or WINE then you should be able
to ssh into it and kill the offending application.

I am so lucky... after 10 hours I can finally connect: the offending soft
was killed by DrWatson!

Is there an alternative of ssh for Windows?...

One thing I would like to do too: start the vnc server with a high
priority thread! There's the command "-service", there's nothing I could
add to increase the CPU priority?..

Server editions of WinNT provide the option to install Telnet.  So
you could telnet inside and do a shutdown/reboot.  But only for server
editions ..

CopSSH is better (easier to install on Windows) package.
http://www.itefix.no/phpws/index.php?module=pagemaster&PAGE_user_op=view_page
&PAGE_id=12&MMN_position=149:149

However, any form of SSH on Windows does not run natively and it requires part
of Cygwin to be installed to provide what in essense is a Linux environment
for OpenSSH to run within.  Login in by this means you get a Linux shell
command line to do things within your Cygwin environment, which should be
installed with limited access onto the rest of the Windows system for
security purposes (privilege separation).  You can of course configure the
system so that you can start messing up with your Windows OS from within
Cygwin, but at the same time you start opening up potential vulnerabilities.
Such vulnerabilities are not to be disregarded if your ssh installation is
poorly configured; i.e. using the default ssh port and weak passwords
like "Tom1", "1234", etc. because a quick dictionary attack will soon crack
your otherwise unbreakable sshd tunnel.

Telnet does not offer secure key authentication like ssh does (although you
need to configure sshd from its default setup to disable passwd
authentication and use SKA instead).  Hence, the previous comments with
regards to vulnerabilities apply, only much worse: unlike ssh, telnet
transmits plain text authentication credentials in the open.  Any router,
switch, proxy, server, ISP, etc. in the middle, can read your "1234" password
and username.  Telnet was a lovely tool back in the seventies when the planet
had three IBM mainframes and all IT engineers knew each other in first name
terms.

In conclusion, you can set up your sshd and Cygwin installation to manipulate
your Windows OS, but I wouldn't readily recommend it.  On the other hand, I
would always recommend to use VNC over ssh, unless you are using the paid for
VNC versions, which offer encrypted authentication.

XP PRo comes with Telnet?  Are you sure?  Well, I was obviously
talking about telnet server, but not telnet client which is available in
every "flavour" of WinNT.

Ah, luck faded away: I opened a simple Font file(!), and I'm getting the
same error again...
There's a mail server and an IM software currently running fine on the
machine... I really can't understand why VNC is so (damn) capricious.

A suggestion for the VNC programmers: add a "user-defined password to
reboot the machine" feature...

Are you sure TightVNC could provide interface of a single application? I've

Re: About single application RFB server

2007-01-28 Thread lizhong
It's strange that the first two web links in your email seems unusable. I have 
found some information about GGI project through google, and I found this VNC 
LibGGI target - allows LibGGI applications to display over the network using 
the VNC protocol. Needs porting from old LibGGI. 
I want to develop something similar like VNC libGGI target, a special VNC 
server based on X-windows, which could provides interface of any single X 
appliction. It would work like this. The user specifies the application he 
wants, and the special VNC server will transfer the interface of that 
application through the network to the user. The VNC viewer does not need to be 
changed at all, for it simply displays what the server gives it.
The main difficulty is how I can separate the interface of a single X 
appliction from the whole desktop. I'am a newbie of X-windows, and I expect for 
any suggestion on this problem. Thank you for any help!

Do you have winsock installed?
Windows file sharing does not require that ;-)

it also could sound like a routing issue so further network information
is required

If you are looking for a flavor of VNC that will export a specific 
X-based application instead of the whole desktop, x11vnc provides this 
functionality.
