Summary: Connecting to PC running TightVNC server - Inflate error

Initial Comment:
I am connecting to a Windows XP machine which is 
running TightVNC server 1.2.9. When I launch CotVNC 
2.0b2 and enter in the IP and password of the Windows 
machine, I get the error "Connection Terminated. Inflate 
error: unknown compressions method."

On the Windows machine, the VNC server indicates that 
a connection was made, but on the Mac, nothing shows 
up.

This error did not occur in 2.0b1.

I tried the latest version of COTVNC 2.0b2 and I can't
connect to the Mac using Apple Remote Desktop in Tiger. It can
connect but I get this error: 
Zlib inflate error: invalid literal/length code

After some tests I figured out what was causing the problem.
I used 256 colors on the client because using VNC  over a
modem is slow. Having less colors makes it a little faster.
Anyway when I changed the connnection profiles to let server
decide it works but with million of colors.

Possible to fix this in a future version of COTVNC?

Confirm this problem here.

I can only connect to a TightVNC server 1.2.9 with Tight encoding 
disabled.

Tight being the most efficient encoding, I'd like to see this fixed!

 Removing "tight" encoding seems to resolve this problem:

Select 'Connection Profiles' from the Connection menu and
desellecting Tight on the Encodings tab.  

The changes do not seem to take effect until to restart the
program.

For what it's worth,

My workaround is simpler:  I only disable "TIGHT."
"ZRLE" appears to work fine.  When I enable TIGHT, I get the same 
inflate error.

The configuration of my Windows machine is 2000 with service pack 3.
I am connected to it over a Cisco VPN tunnel.

I can confirm this on my setup: connecting to TightVNC 1.2.8 on Windows 
2000 PCs from Panther OSX with CotVNC 2.0b2 ... I see the same error 
dialog.

Disabling both ZRLE and Tight encodings in the profile allow 
for connections to be made to a Windows XP machine running 
TightVNC server over a LAN. However, enabling both settings 
results in the same "inflate" error with 2.0b2.

My situation was over our office LAN, *not* a VPN. On 
Monday morning, I will try it again with both those options 
unchecked in CotVNC.

Clay, you say this works if you don't use the VPN tunnel.  Does it work 
with ZRLE and Tight enabled?  In other words, is it the tunnel causing the 
problem or the encodings?

I'll test against TightVNC and see if I can duplicate - we've done all of our 
testing against the current RealVNC.

Sorry if this winds up being a double-post - I can't see my post show up. 

I have figured out a work around for this bug. I was having the same 
problem as you. Disable the ZRLE and Tight encodings in your profile, 
and try again. Then you can connect.

I HAVE FIGURE OUT A WAY AROUND THIS ERROR - I had the exact same 
problem and scenario. When I edited my profile to disable the ZRLE and 
the Tight encodings, and used that profile to connect to the Win XP client, 
I successfully connected.

I just got this same error, same situation, connecting to Win XP client 
running TightVNC 1.2.9, from my Mac over a VPN and I'm using CotVNC 
2.0b2

See my thread after yours.
