'[TECH] VNC Client?'
2009\08\22@234539 by Josh Koffman

Hi all. I have a unique situation that I think can be solved via VNC,
I'm just not sure what the best way will be.

I have an application that won't work over a wireless network
connection as it's very picky about latencies. What I'd like to do is
run the application on a wired computer and control that computer via
a wireless VNC connection. It should work as I know other people have
done it in the past.

Here's the wrinkle. The wired computer is a Mac that runs the program
in question in WinXP via Parallels. I'm not sure which OS should run
the VNC server. OSX has a built in server (which would be convenient)
while WinXP would require more software installs. Anyone have any
recommendations about that?

Also, we had a discussion about VNC clients back in 2007 and it seems
folks were then using RealVNC, UltraVNC, and TightVNC as Windows
clients. Does anyone have any recommendations about the relative
benefits or problems I might run into with any of those?

Thanks!

Run the VNC server in WinXP.

Alternately, it may be better to just use Remote Desktop if you only  
need to have one person at a time connect to the XP machine.

TightVNC is a good Windows client. I like JollysFastVNC as a client on  
the Mac.

Quick comment.
Not 100% apposite but may have some value.

The people who give away the reasonably good [tm] Comodo firewall,
antivirus etc make their money on secure SSL systems and certificates.

They have a remote product that uses their own instant messenger
system and allow secure access to your home system over eg WiFi
systems from airports or cafes.

How or if it fits into your rerquirement I don't know, but worth knowing about.

Hi Josh.

I am a big fan of Remote Desktop. For what it's worth, I use Linux
wherever I can, but, Remote Desktop is one microsoft product that
really, actually, works. It allows me to work from home one day a week,
and it is more efficient and reliable than VNC. The Remote Desktop
system is also more intelligent than VNC... it makes sense (for the way
I use it) to lock down the local machine and re-direct it to the Remote
client. With VNC on the other hand, the local machine is still active,
and people can 'see' what you are doing remotely.

Still, I also use VNC, and particularly, TightVNC. For one reason in
particular: It can expose the VNC desktop in a web browser using a Java
applet.

This allows you to browse in to a VNC desktop from anywhere, without
having to install any 'different' client software (you need a
Java-enabled browser).

http://www.tightvnc.com/doc/java/README.txt

So, there is no Microsoft software I actively recommend to people other
than Remote Desktop, and, of the VNC's, I use TightVNC for the web-based
interface (although it is possible other VNC's have a web-based
interface too).

Here's a little update. I just managed to try Windows Remote Desktop
today. It worked...but only sort of. It seems to have some issue when
I send characters from a USB HID device I made. The characters appear
ok, but the shift status seems to only be correct about 25% of the
time. This is a bit of a problem as the program I'm controlling is
case sensitive. I was a bit surprised, but when I switched out of the
Remote Desktop viewer and into notepad my device was sending the
correct commands.

So...now I guess I'll try a VNC to see how that goes. Is there really
any difference between TightVNC and UltraVNC? Anyone have any
experience with a Win7 viewer?

Thanks!

Josh

FWIW, I'm using Remote Desktop all the time with various USB keyboards
-- i.e. USB HIDs --, and never had a problem with the shift status.

Most of the time I do not have problems either, however, at least twice a
week either the CTRL, ALT or WIN key stucks so when I start typing a command
on the CMD window or FAR manager some weird effect arises -- then it takes a
little hassle to get it back to work. The problem only occures if I switch
to the host computer and back to the remote desktop.

BTW I do not use USB keyboard, however, I do use a KVM for remote accessing
to the host computer -- it is a strange but necessary security setup for my
job.

What do you call "host"? How do you switch? I simply Alt-Tab into the
Remote Desktop window for switching to it, and click on a window outside
it for switching back to my local system (since the Alt-Tab is stuck
inside the remote desktop).

Can you please elaborate a bit how this is set up and how this enhances
security?

Thanks,

I mean the computer that runs the remote desktop client. The screen and
keyboard provider.

Usually I use it full screen mode -- when need to switch either move the
mouse to the top of the screen where the remote desktop menu pulls down so I
can click on the minimize button. To switch back to the remote console I use
alt+tab or the mouse to select the remote desktop client from the task bar.

I work in the antivirus field, installing, testing, debugging and
disassembling malwares and spywares on the so called infection machines.
These machines are inside the laboratory where there is no live internet
access to the outside world. Not even to any other internal network so no
malware can break out of this jail. You are not even allowed to bring any
laptop or wireless devices, bluetooth has to be turned off on your mobile,
no hard drive, CD.DVD or USB etc allowed either... this is the only way we
can protect our customers and ourselves against an unfortunate accident.

The production machines do have access to the outer world but those are
outside of this lab, totally sealed off from this contaminated area. To be
able to work inside the lab with these computers we have the KVM system so
the screen, keyboard and the mouse can be accessed from inside.

Ok... but then you don't use Remote Desktop, right? You use the KVM
switch to switch the keyboard between your local computer and another
computer? I wondered how this KVM switch issue fit into the Remote
Desktop setup.

I do use Remote Desktop -- there are some other production machines that I
access to via Remote Desktop. The KVM is only an extra layer on this config
-- only mentioned it as I have this shift/ctrl/alt/winkey status issue with
Remote Desktop and it might related to the KVM.

Ah, now I get it. Now that you mention it, I've had that also
occasionally with a KVM switch years ago, without Remote Desktop.
