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 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.

    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.

    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.

    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.

    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.

    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.

    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.

    I can duplicate this error as well on my system. XP running
    TightVNC 1.2.9, inflate error.

    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.

    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.

    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!

    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?
