UltraVNC

Well it looks like I can answer my own question and confirm AUTHHOSTS= line has a max of 150 chars.
I wish it was more ...like 255 chars - but I guess that is a developer choice.

Code is located in
uvnc_settings.cpp line 53 and line 320 both have have a hardcoded "150"
char authhosts[150]=("\n)

The UltraVNC.INI AuthHost= is cutoff and ignored after 150 or so characters.

Using 1.2.0.6 with INI file on Windows 7 64 bit.
Clean/fresh install of UltraVNC then copied over our INI file - shown below
Note the line

AuthHosts=-:?172.26.3.9:?172.26.3.57:?172.26.3.10:?172.26.3.13:?172.26.3.16:?172 ...
