UltraVNC authentication issues
A user reports authentication issues when using the UltraVNC server:
We have UltraVNC (various versions but mostly 1.0.8.2) running on various computers on our network. They’re a mix of Win7 x64 and WinXP x32 (plus Solaris 10, Slackware 12 on standard VNC). They can all VNC connect to each other as can assorted iPhones, iPads, HTCs and Samsungs with VNCViewer. The iPads and iPhones also run Touchpad for remote control similar to Valence.
I’m clearly doing something wrong with setting up Valence on my S3 however because I’ve yet been successful in getting it to authenticate with any of the systems. I’ve tried changing passwords, no passwords, changing the port config. It always connects instantly (faster than Touchpad) but just then I always get the error “could not authenticate with server”. I also tried connecting from outside using a PPTP VPN but had the same result. I would’ve tested it over the L2TP/IPSec VPN which is more reliable but that seems to be broken on the S3. The internal network is single switched subnet with no intervening firewalls except on the gateway.
