Samba config for Open PS2 Loader (PlayStation 2)

smb.conf

# This setup works pretty well for OPL with a network link that travels through
# two UniFi switches and connects to a Samba server running inside Docker. The
# host OS is Debian with a ZFS filesystem and the container OS is also Debian.
# Latest Samba (4.11+).

# Lower the minimum protocol to NT1 (a SMB1 dialect), this is required since

# Tweak socket options for lower delay. We also set TCP_KEEPIDLE to 20s which is
# about what it takes to reset the console and launch OPL, this avoids keeping
# file locks around for too long. We could try to optimize socket buffer sizes
# but Linux should do this automatically.
# TODO(mafredri): Do more testing with TCP_QUICKACK.

i tried opl 1.0, 1.1.0, and latest beta. also done enable read/write write. issue persists.

i use NixOS. samba 4.15.0

@gdfsv ok, sounds like you have the bases covered in that department. Did you try changing the game modes (and experimenting with different combinations) in game settings (inside OPL)? That's the only thing I can think of that could help assuming the game is playable over Samba. That's about all the help I can provide in this instance.

add this line for passwords to work in OPL:
ntlm auth = yes

If it still doesn't work, make sure to create a samba user:
sudo smbpasswd -a samba_user, where samba_user can be the username you want.

Restart the smb and nmb services with systemctl then open OPL and use the USER and PASSWORD used for creating the samba user previously.

write cache size is not present in samba 4+ afaik

Sorry for necroposting, but using this config and modifying it line by line - I got result of simply hanging samba docker container after few packets exchanged. Probably not connected with this config itself, but i'm wondering what effectively "kills" the process running on the container (Alpine and vanilla samba there - nothing else)

@tomeq82 are there any logs for the container? you can run the following command to see the logs for the container: sudo docker container logs CONTAINER_NAME

just replace CONTAINER_NAME with your container name or the container id

@SpazCode153 in fact, I have a lot of the debugs - I enabled level 5, then reduced do level 3.
Each time it says "waiting for connections" is my restart of the container as it simply exits/dies.
Also, any meaningful error is something like that when tried to read the file:

https://pastebin.com/RSLTcRhv

and here are the other logs:
https://pastebin.com/0sm1hcrp

What is surprising it is not repatable situation eg. sometimes I got into listing of the particular game inside the share, but most of the time it simple drops error 300 or 301.

@tomeq82 Just to confirm, your PS2 is directly connected to the samba device via LAN cable? What device are you using to share your games via samba?

@SpazCode153 no, PS2 is connected to the same lan as NAS hosting the container with samba. Docker container, vanilla alpine linux + just samba packages.
