You could try to slide the parsing backwards and forwards in the buffer, until you hit the spot where it all fits. But I'm far from perfect :-), somebody else might spot something, so I'm sending this to the list.

RE: VNC Password Authentication vs. Windows
I understand there is a challenge/response mechanism used in RealVNC Free Edition, but is this authentication session encrypted? What safeguards are in place and how do they compare with a default setup of Windows 2K/3K, for example? VNC Free Edition uses a simple challenge-response scheme based on encrypting a random challenge with up to 8 bytes of password data. VNC Personal Enterprise Editions set up an encrypted session between viewer server before exchanging passwords, which may be up to 255 characters in length.

excessive memory use in VNC server on Solaris
Hi, I'm using the 4.1.2 Free Edition on Solaris 10. Recently (ie this morning!) we noticed that one Xvnc process's virtual memory size had grown to about 4GB (the worst case), with most of this resident in memory, forcing other processes to be swapped out. As I'm used to seeing Xvnc sizes like 20/30MB this was a bit of a surprise, to say the least. Has anyone else exerienced this and if so is there an explanation please? Apparently we have recently installed a new screenlock program into all sessions and I wonder if this may be the cause.

Re: excessive memory use in VNC server on Solaris
I've seen a similar issue on our Solaris 9 systems, but I rarely saw the memory size go above 500 MB. We had been running VNC 3.3.3r2 from ATT until very recently when I switched that out with RealVNC (Free) 4.1.2. This upgrade was being done to fix two problems, one of which was the memory usage. We haven't been able to track down the triggering event (specific X application or length of time the session is running). I've been meaning to run a debugger on a running app that is using memory like this to send info about how much RAM is allocated for what PS: Is there any way to configure the vnc-list mailing list server to add [vnc-list] to the subject of e-mails?

Cannot connect from work
I'm trying to connect to my RealVNC server that I made at my house from work, but at my job everything is on a proxy server. It allows traffic on ports 20,21,and 22. On my vnc server properties, I accept connections on port 22, and I followed instructions for my WRT54GSv4 linksys router on portforward.com but I still cannot connect. I know it can be done, because my co-worker does it all the time. He uses the beta version however, while I use the 4.1.2 RealVNC Free Edition. My laptop that I take with me to work is on Windows XP, as well as my home computer that the VNC server is on. Is it my router, or do I have to do something else. I put the number 22 on Accept Connections on port: in the properties on the server, just in case that helps. Check out the new AOL.
