Filetransfer Tool

[Oeschey, Lars]

Hi,

we currently plan to replace our Remote Control Tool (PC-Duo if anyone wants
to know, quite cool, but also expensive) with VNC. Nearly all features of
PC-Duo are also in VNC, though it is a bit slower. What I miss is a
Filetransfer Tool, since our users need that (all on Win platform), and
perhaps Clipboard transfer.
Does anyone have an idea regarding the filetransfer? Perhaps some
lightweight freeware ftp for Win, that we just start when needed?

Tight Encoder

[Oeschey, Lars]

Hi,

did anyone use the Tight Encoder Version a lot? Is it stable enough? The
author states on his homepage, that he didn't run or test it, and that
there's no support for it availible.
Bevor we deploy it to LOTS of machines, I'd like to know, if there are any
known issues with that version.
Since we mainly have 64k/128k lines, we need some kind of effective
compression, and I found (subjective) tight the fastest.

I have to admit that I prefer the non_installer versions. Makes it easier to
auto-install.

I'll do. What would be really cool, is disabling the wallpaper (yes, we
mainly have windows platforms :(). Do all those contributions perhaps one
day flow together into one release? for example, I could use the wallpaper
feature and the tight encoder, and I don't have a _clue_ about C and
compiling (besides the usual ./configure make stuff).

Tight Encoder and Win2K?

Hi,

is it possible that there is a problem with the tight-encoder version and
Win2K? I copied the "tight"-files over the existing ones (which worked), and
now I can't connect any more.

Tight Encoder + Win2k -> no connect before Logon

[Oeschey, Lars]

Hi,

what I found out now, is that one can't connect to a Win2k Machine when
there's noone logged on. I guess this is not a fault of the tight encoder
version, but a generic VNC problem? Could anyone clarify this?

ok, I got that working now. Just two questions for understanding: When I
look at the port setting in the registry, it says 6600, shouldn't that be
5800?
For automatic deployment: If I only copy the registry keys from HKLM to a
fresh machine, with only the binaries copied to it (and winvnc -install
ran), are those settings copied to the users registry when one logs in? So I
wouldn't need to care about user settings?

Is there a way to set default Options for the viewer? Our ppl most time

I guess this is the saving of _single_ sessions, including Client IP and
stuff... You're right, this isn't quite what I need, since we would have to
have 10.000 desktop icons for every session then ;) What I need is some kind
of default for the viewer. I found an empty registry Key under HKLM, not
sure what goes there...

Win2k logoff disconnect

[Oeschey, Lars]

Hi,

I have a strange problem on my Win2k test machine: When I go
"Start/Shutdown", usually the logoff options should be displayed, i.e. Log
User off, reboot, shutdown. But as soon as I click the "Shutdown" Option in
the start menu, I don't get any screen update any more. When I check the
machine locally, the Options are displayed as expected. I just don't get
them in VNC. This would sound like a difference between the default and user
settings, as I had before, but I deleted the complete ORL tree from the
HKEY_LOCAL_USER registry, so that the default settings had to be used. With
the user logged on, I also verified that the default settings and the user
settings display the same port.
Are there any registry settings I am missing?

An update to this: The screen is diplayed, but I get refreshes like every 10
mins. It gets horrible slow, like a 240baud connection. I even can't move
the remote mouse... The whole thing happens only as longs as the Logoff
Options are displayed, no idea why that is. I use Tight encoder.

Found something else: when I connect to that machine (which is connected
over a simulated 64k connection with 2 cisco routers btw.) with the browser,
I can watch that phenomen: when I click Start/Shutdown, the screen gets
drawn in "lines", i.e. you can watch lines drawn from the upcoming Options
screen downwards, after it reaches the bottom of the screen it draws from
the Options menu upwards, until all the screen is redrawn. Then I can move
the mouse again, and everything seems normal. As I connected with the
browser, the Tight encoder version can't be guilty, since it doesn't get
used there... It must be something with the way Windows darkens the whole
background when displaying the Logoff Options.

ok, bear with me... hit me on my head... after taking a sharp look at the

didn't use encoding. After changing the binaries, it works fine now. 

Sorry, Lars

this would be something I'm also interested in. So far I have planned, to do

what happens to me sometimes, is that the password window is hidden behind

guess.

who is connected?

[Oeschey, Lars]

Hi,

is there any plan, to implement a feature that tells you WHO is already
connected to some client? What I mean is, if you connect to a client, where
someone already is connected, you can set "CennectPriority" to "2" to deny
the new connection, which is good. But since we have quite a few
administrators spread over some buildings, it would be good to see who is
connected there (perhaps some reverse DNS lookup, or ARP cache readout?).

this is quite true. The Internet is _no_longer_ the Usenet, but the Usenet
is an essential part of it. Of course, as with IRC, there's a lot of abuse.
But if you say, forget about Usenet, you could as well say, forget about
ftp, smtp, and all the other little protocols that make the internet.
The Usenet will stay for quite a long time, and if only because the WWW (the
youngest part of the net) is not sufficient for that (news reading on deja
isn't really fun).
As said before, for administrators (and VNC is used primarily by
administrators I guess), Usenet is essential.
And of course, the Usenet will also be used by administrators primarily,
because they _know_ about it ;)
That's why there's mostly computer talk on usenet.

[OT] Methods of security

[Oeschey, Lars]

Hi,

since there are abviously some poeple good at security on this list, I'd
like to ask, if they could point me to some good literature (preferred
online), about implementing security methods, or more specific, user
authentication.
Since we are in the process of developing a completely new
Goods-Management-System (dunno what it's really called in English, the
software that runs in outlets, connected to a database, managing all the
sales of goods), I am expected to present some model on how user
authentication should look like. At the moment there is no security at all,
and we have problems, because the wrong poeple do wrong things in databases
(developers ;)).
