Duck Chess

[hgm]

When you run the engine command you use from a terminal (after setting up the Linux part), what does it say when you type 'uci' to it?

[rgrosz789]

I get no response after UCI:

[hgm]

You are doing this on the server (Linux) side. Of course nothing happens there; the server is waiting for a connection request from the network to come in, not at the keyboard. You should do it on the (Windows) machine where WinBoard uses connect.exe as an engine, to check in the terminal whether running that same command indeed behaves as an engine.

[rgrosz789]

Sorry, I assumed that "in the terminal" was a reference to the linux PC.

I'm not sure how to run UCI on the windows PC. I tried running this at the command prompt, but nothing happens on either side:

e:
cd TV
cd PIX
cd Duck-Fmax
uci2wb.exe ./mayhem/"mayhemduck-23.exe"

[rgrosz789]

Then I tried this command:
connect64.exe -p 27015 -pw "Have fun, have WinBoard!" -fUCI 10.0.0.41

and got this result:

# waiting to connect
host = -fUCI, port = 27015
telluser (-fUCI) Unable to connect to server!

[hgm]

Well, -fUCI is not an option that means anything to connect.exe. So it doesn't recognize it as an option, and thinks it is the domain name of the server it has to connect to. Of course the name server of your LAN doesn't know any computer of that name, so the attempt to connect to it fails. And this is then what connect.exe reports) (In a telluser command, so that when you would have been running it through a GUI instead of in the terminal, that GUI would show you a popup with the error message.)

Leave it out so that connect.exe understands that it has to connect to 10.0.0.41 .

Sorry, I assumed that "in the terminal" was a reference to the linux PC.

I'm not sure how to run UCI on the windows PC. I tried running this at the command prompt, but nothing happens on either side:

e:
cd TV
cd PIX
cd Duck-Fmax
uci2wb.exe ./mayhem/"mayhemduck-23.exe"

'Terminal' and 'command prompt' are synonyms. Or, strictly speaking, 'command prompts' is a pars pro toto, symbolizing the terminal window because it appears in the latter.

I am not sure the Windows command interpreter understands the way you use quotes. Or why you use quotes here in the first place; there seems nothing between the quotes that would not be understood the same way without those (such as spaces, which otherwise would be interpreted as a separator of command arguments).

Otherwise this should work. Provided that:
1) uci2wb.exe is inside the Duck-Fmax folder
2) that folder has a sub-folder 'mayhem', which contains a file mayhemduck-23.exe
3) that .exe would not expect any files in its own folder (such as books, config files...).

[rgrosz789]

I had some success last night, using either engine definition in winboard:

connect64.exe -p 27015 -pw "Have fun, have WinBoard!" 10.0.0.41
"connect-no-pw-no-UCI" -fcp 'connect64.exe 10.0.0.41'

But today I could not get any moves played from the linux side. I need to do more testing to figure out what does work consistently

[abulmo2]

Based on the difficulty with running some executables on my old hardware, I decided to buy a newer PC that will be dedicated to linux. Hope that will allow me to do more testing of Duck chess engines.

One thing I would like to try is playing the linux version against the Windows version of one engine (say Fairy Stockfish or MayhemDuck). I searched on this forum, but didn't see a discussion of setting up a tournament on a local network, between multiple computers.

I use ssh to play my engine Dumb from a raspberry pi on my main PC. Here is the command I am using to play rpiDumb during the monthly tournament and to get the display with woard on my main PC:

Code: Select all

xboard -zp -ics -icshost nightmare-chess.nl -icshelper openseal -fcp "ssh pi@192.168.1.38 bin/dumb-1.11" -fd $HOME/bin -fUCI -autoKibitz -fSAN -defaultHashSize 1024 -sgf joost-dumb-2023-01.pgn  -debug

I published MayhemDuck 2.4. It scores 90% vs v2.3. Lots of improvements.
Calculates much deeper.
Better opening book.
Bench: 5939296

I decided to make a 3 game 60+2 minimatch on youtube:
( The 3rd game lasted forever ... )
So people see how Xboard looks on Linux.

v2.4 vs v2.3

I'm trying to run engines on my main Windows PC (with WinBoard) against engines on a Linux PC.

I have not figured out the equivalent of using ssh from Windows to connect to the Linux PC. Based on Google searches, I should use PuTTY under Windows:
