proxy authentication information in vncviewer

[bla]

Hello !

My computer on work is set behind a proxy which needs authentification with username and password.

how can i give this information to the vncviewer ?

You probably can't.

But you'd probably need to tell us a little more about the situation.

Normally network proxies/firewalls are for OUTBOUND communication, meaning the local LAN users need to authenticate with the proxy in order to browse the outside web or connect with outside Internet services.

It's not typical for a "proxy" to be involved for INBOUND connections. Are you connecting from home into your work office? Or are you trying to use the VNCViewer from within your office to connect with an outside VNC server (e.g., at your home)? If the latter, I don't think standard VNC has any way to support that; I may be wrong.

In any case, please explain a bit more about where things are, what's communicating where, the kind of proxy/firewall, and the prompts you're getting and when.

i try to access my home computer from my workplace which is behind a proxy.
ports 80 and 443 are the only ports which are able to pass.
i figured out the whole thing with port forwarding etc.

i think all this information are not important. the only thing that matters to me is:

How do i give the authentication information [username+password] of the proxy to the vncviewer ?

i saw that REALvnc is able to use the proxy-settings of the internet explorer in the enterprise edition. but this application is not freeware.

at the moment i am using teamviewer which works with repeater and that works fine. actually a repeater should not be involved in my long time solution. thats not a "clean" solution.

So as I said, you can't. Your workplace has its firewall designed to prevent exactly what you're trying to do. They will only allow proxied http connections. Standard VNC is not a proxyable VNC connection as far as I know (and certainly not an http one).

There are workarounds but most involve a 3rd piece (such as a repeater).

I'm curious how RealVNC does it, and whether they actually depend on a running server at RealVNC to handle the translation between RTP and http... oh I just realized -- all they have to do is force you to use RealVNC Enterprise at both ends, and they just talk http the whole way. So you end up with a solution incompatible with other standard VNC software.


Oh, and FYI, the reason "all this information" was important for you to describe is that we <i>can't read your mind</i>.

B, i know this topic is old but it is the younger i found. Regarding connecting to a server through a company proxy, you said is impossible and that RealVNC made it running Enterprise Edition at both ends.
Well, is not like that, they just do it... i don't know how.

Right now i'm connected to my home-pc server. The server is Ultra VNC. Nothing special, just configured on port 80.
Client, here, at work, is REAL VNC Enterprise, and setting "use internet explorer proxy" and connecting to IP::80, works smooth.

I hope Ultra VNC adds this feature soon, because i really like it


Damn with the anti-spam thing... is almost anti-human!!!
