VNC and TCP wrappers

Discussion:

Has anyone made any attempts at getting VNC to use Linux tcpwrappers? It
would be very convenient if the sever could be restricted by the same
hosts.allow / hosts.deny that are already there.

or, something built into Xvnc that reads hosts.allow / hosts.deny.

just some thoughts...

Yes, I've prepared a patch for this for Xvnc. You should be able to find
it on the VNC contribs web page; otherwise contact me.

Here's a crazy Idea..... (sorta taken from Slashdot.org)

How about a client for the Sony Playstation? Hook-up a modem, cable, dsl,
or some other interface(It's got a parallel interface of some kind and a
serial interface of some kind, you can buy mouses for the Playstation, and a
keyboard hack could be done ) and work at home through Playstation, Nintendo
64, etc????

Not insane, but certainly a lot of work for somebody. I'm not sure how
many people would make use of it though. The CE/Pilot ports are nice,
but probably only get used in anger a relatively small amount. I have a
CE machine and have used the CE port, but not often.

The PSX's lack of mouse/keyboard/ip connectivity as standard could
really limit things. I don't know much about this, but I'd reckon they
aren't something most PSX owners have and as an obscure add-on are
probably a mite expensive.

Can you get a Java capable browser for the PSX? If so, that is probably
a more viable option, using the Java viewer.

If you got it to work, you would be looking at a fairly impressive bit
of "platform independance" though. Wouldn't fancy anything above 640x480
on blurry TV screens though.

The N64 is probably out as cartridges are not something most people can
make. Even the PSX is a bit of a pain as you need a "chipped" one to
play non-PSX CD's.

Just my opinions, ignore the rubbish I spout.

Another thought, the new "hot" console, the Dreamcast is a tie-in with
Microsoft, runs a variant of CE and almost certainly is going to have
more of an overlap with PC's.

While the CE port of VNC (or any other normal CE apps) probably won't
work on it, I bet there will be a Java-capable version of IE for this
machine at some point.

All pure speculation of course, I don't even know what it looks like,
let alone it's specification and features.

I'm sure a poke round the WWW could answer a few questions.

This doesn't help the installed base of PSX owners much anyway.

I can feel this getting off-topic so I'll stop now. Especially as I
don't know what I'm talking about.

I have been using VNC to access a financial application (lot
of text fields and tables - almost no graphics). There seems
to be a problem when I use the Java client (through hostname:5801)
and the NT machine is set for 256 colors. I hope that someone
has already found this problem (and a solution).

Problem Summary:
When drawing large rectangles of solid color, the right side and
the upper side of the rectangle is drawn with the wrong color.
With this configuration the problem occurs on all possible values
of "options", with the exception that for "encoding=Raw", the
problem can not be reproduced, but than the performance is so
bad, that it is not a good solution.

Environment:
NT/4.0, 256 colors: IE4, and Netscape 4.05

To isolate the problem I've tested several environments, which
all seems to work OK:
Same as above, with 65536 colors: OK
Same as above, with Encoding = Raw: OK
Same screen, Netscape 4.05 on unix Box: OK

I've using 3.3.2 on an SGI machine. I will appreciate any input
how to get the above configuration to work with reasonable
performance.

Thanks

I thought Sony had canned ideas for a modem, and I've not seen keyboards for
either playstation or N64. Wouldn't it be better just to use a cheap old
386 or something?

Or an old Amige 1200 or similar, since there is a viewer for that (albeit
an 8-bit truecolour one...)

Ohh James.

Hope thats NOT a poke at the AMIGA <wink>

as it happens, i'v just found VNC about an hour ago, after
i had tryed 'anywhere' and mentioned it to a PC friend.

heres the short doc:
Short: View&Contr. PC or Amiga Scr. on PC w.TCP
Uploader: ***@Grundig.co.at (Bernhard Trzil)
Author: ***@Grundig.co.at (Bernhard Trzil)
Type: comm/net
Requires: A TCP-Stack / Cybergraphics >=V2 with a 8 Bit Mode!

Support Homepage: http://www.geocities.com/SiliconValley/Peaks/9901/

This is a Beta version !
This is freeware, but PLEASE E-Mail me if you use it frequently.

How to use:

Amiga->PC:

PC:
Start "Anywhere.exe" on PC.
Execute menucommand "Anywhere/Listen for a connection".

Amiga:
Start "Anywhere <Hostname>". (Replace <Hostname> with the Hostname or IP-Adress from the PC.)
Be sure, that the PC-Hostname is listet in the "Hosts" list.

Now you should see the Amiga screen on the PC.
You can control the mouse and keyboard over the network.

PC1->PC2:

PC1:
Start "Anywhere.exe" on PC1.
Execute menucommand "Anywhere/Listen for a connection".

PC2:
Start "Anywhere.exe" on PC1.
Execute menucommand "Anywhere/Connect to a Server", and type the Hostname of PC1.

"Anywhere" PC-Version:

Features:
Runs on >W95 or >NT 4.0.
Send screen in 8/16/24 Bit.
8 Bit mode is compressed with special delta/runlength/huffmann encoding.
Recive screens with 8/16/24 Bit in all resolutions. (Display on remote-pc can be different!)

Missing:
None so far.....

Bugs:
Sometimes you have to activate the servermode manually. (Menu Settings/Servermode)

Commandline:
-server Start as Server. Iconified and waiting for a connection.
-comp Enable RL/Huffmann compression.
-moves Send mousemoves.
-force8 Force to send in 8 Bit mode.
-? Help

New since V0.95:
-client If a connect comes, go to client and set the remote computer to servermode.
-connect PC_Name Connect automaticly with the given computername.

as you can see it has the same kind of stuff VNC has, but seeing as
VNC is on more platforms it has the edge i guess.

its only a guess as i havent been able to get the win95 and AMIGA VNC(vva)
working yet.

winVNC3.3.2 , vva 0.1.2 (08-Dec-1998)

anywhere is dead simple to use and works well enough viewing the AMIGA
picasso screens on the win95a machine.

has anyone got vva working yet ?, it just comes back
'Could not connect to VNC-server' even though the null-modem
connection is working fine,the win95slave is running wingate2.1d
and the AMIGA miami TCP/IP.

the pc is called 'windows' 192.168.0.1
the AMIGA 'amiga' 192.168.0.2

i'v tryed both the names and the No. to try connecting with no luck
so far, i'm hopeing its somthing simple i'm missing/forgeting to do !!.

i'v also passed the VNC site to the KOSH MLs so hopefully there will
be many ports of the useful OOR SW given time.
