AmiVNC won't connect

[Michele31415]

I'm trying to get an AmiVNC server running, but I'm getting:

Genesis is running, I can ping the Amiga, and both ftp and AWeb-II work OK.  But if I try to open a vncviewer from my PC to the Amiga's IP:5900, it goes "connection refused".   The Genesis log creates a line "Access from 192.168.0.xx to port 5900 denied".  Same thing trying to connect from the Sun.  What am I doing wrong?

UPDATE
The answer to that problem was here: https://forum.amiga.org/index.php?topic=50301  I just needed to add a line for port 5900 in AmiTCP:db/inet.access

Now I can connect and open a vncviewer window but it's all black, so we're not quite there yet.

But this was with amivnc 1.0.0, so I downloaded amivnc4.  This one won't even start up:

Genesis is running

Genesis has a port filter which by default rejects all incoming connections. You have to add an exception for port 5900 to that filter. Or remove the default rule.

Thanks, yes that fixed that.  Now I can open a connection but with amivnc 1.0.0 all I get is a black window in my vncviewer and with 4.0 it says amivnc isn't even an executable file.

AmiVNC4 is AFAIK only for OS4+.

Arrgh - thanks, you're right - and it says so right in the readme.  I skipped right over that.  Duh.

So now we're back to v. 1.0.0.  I thought maybe it didn't like my display mode.  In the readme it says:

To run AmiVNC you need :
- any native planar Amiga screenmode (PAL, NTSC, AGA etc.)
  or 15, 16, 24 or 32 bit RTG mode (CGFX or Picasso96)

I had Picasso96 running on my Spectrum at 1024x768, 8 colors.  That produced a black window of 1024x768 in vncviewer.  I switched the screen mode to 1024x768, 256 colors.  Now when I run vncviewer I get a window that's 1024x8, and then it quickly closes itself.  The amivnc log is now:

So there must be some screen mode issue going on here.  Does anyone have amivnc running with Picasso96?  In what screen mode?

[nbache]

If it wants 15 bits as the lowest RTG mode, 256 colors doesn't sound like enough. 15 bits would be 32768 colors.

But I dont remember exactly how those modes work under classic. I use ARGB32 on my OS 4.1 WB.

It's been a long time since I dabbled with VNC, though.

I guess that's the key then.  However, I can't seem to be able to find a 1024x768 mode higher than 256 color that doesn't end with either "Screen too large for this card! Sorry.", "Signal over range" (on the monitor), or no signal at all.  I've tried HiColor and TrueColor, both interlaced and non-interlaced.  Maybe I'll try a different monitor.  I don't really want to have to run in a lower resolution just to please AmiVNC (which apparently runs very slow anyway).

UPDATE:

It appear from reading the Spectrum manual (p. 1.8 ) that 8 bit color is all you get for a Workbench display at any resolution, even down to 320x200.  1024x768 16 bit color is only available on an EGS display.  And since I'm using Picasso96 and not EGS, I guess you can't get there from here.  No AmiVNC for you!
