Error: Your connection has been rejected.

[noIdea]

Hi,

I am running UltraVNC server on:
Windows XP SP2 (latest updates installed), 2GB RAM, Intel D 3GHz

and UltraVNC Viever on:
Windows XP SP2 (latest updates installed), 1GB RAM, Althon 1700+

When I installed server for the first time, it worked well. I could connect to server without any problem. I tried to use VNC password as well as MS Logon and it worked. After some time, it stoped to work. When I tried to connect using viever, just window title on the top of the screen appeared, but it was immediately closed. When I tried to use Java viewer I got error message:
Error: Your connection has been rejected.

I tried a different configurations but, no one worked. Finally I tried to reinstall server (uninstall and install) and it started to work again. It worked for 5 days. Now I am getting the same behaviour as before and I am not able to connect. I am not conscious of any changes on both computers that could cause it. I use it to connect from home to my office. I have unrestricted ADSL connection at home, and UltraVNC is fully supported in our company network. Also other people use it, and they do not have such problems. Currently I use VNC password and Keep existing connections option. I use OpenVPN to connect to company network. But I do not think, OpenVPN could be a problem. Although I do not know. I am on the ropes.

Deos somebody have any idea, what can be a problem?

Thanks a lot.

Is anybody using RDP when you are trying to use UVNC?? I have seen that cause problems.


Will it work in the lan?? Or are you having the same issue??

Yes, it works in the lan. There is not RDP allowed on my computer. But my colleague use RDP on his computer, and we are on the same switch. Could it be problem?

But he is not connected at the moment, and I just tried to connect, but it does not work.

ok.. do you have a static routable IP or is your IT controlling your network flow. If it works in the lan with no problem and not accross the WAN then it maybe a router issue

dynamic IP at home, static IP at work

But it worked also accross the WAN. I already was connected.

The problem is, that is only my problem. A lot of people in our company use it, and they don't have such problem. Only me. Could it be some problem on my home router? I can't imagine what it can be.

maybe your home connection is dropping packets... kinda out of ideas at the moment..

So I will try RDP. Only to test if it works.

well if you have a hugh amount of traffic flow then you can lose a connection or a connection can not be established but it would have to be almost your entire bandwith

Hi All,

Can anyone explain why we are disabling the Nagle's algorithm in the code by using setsockopt(sock, IPPROTO_TCP, TCP_NODELAY, (char *)&one, sizeof(one)).
What can be the possible disadvantages of not keeping the recommended option of leaving it enabled.

Thanks in advance,
Praveen
