I've heard many negative comments about VNC. Now I started using it and I think it's pretty convenient way of remote access. It is cross-platform, at least as far as win2k and OS X go and I guess Linux too, and unobtrusive. Why nobody likes it?

It's a free remote access software, kind of like remote desktop.

We just tried it today across win2k and osX and it worked. Now, VNC kind of has bad reputation so I want to know why.

VNC rocks. the only downside is it is not secure and sends passwords via plain text, so using it over unprotected networks (ie: the internet) without first building an encrypted tunnel via SSL, SSH or PPTP/L2TP/IPSec is not a good idea.

other than that, it is one of the greatest utilities around. boxes you want to control aren't always on the same floor/building/city/country, and VNC is a saviour in that department. i just hope someone makes the effort to introduce a secure version of VNC in the near future, and it will be perfect.

TightVNC is supposed to button up the common security issues of AT&Ts standard VNC. I use it on all our office systems so I don't have to get up and go to the desks all the time to tell someone to "click here." Linux also comes with it but I have never gotten it to work right (I just get snow). I also use it to queue up something at home from work.

tightVNC implements jpeg compression on a display. it doesn't use any encryption on the data that travels between client and server. as such, and packet sniffer could be used to check the contents of packets and filter them for keystrokes to guess passwords and the like.

any other code tidy up i'm not aware of, but all of the VNC projects are open source, so they probably share most security features anyway. i know tightVNC has added the ability to change the default ports in the latest version, which makes me very happy.
