Samba config for Open PS2 Loader (PlayStation 2) with password support

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
# Samba 4.11 changed the default and deprecated SMB1.

# https://github.com/ps2dev/ps2sdk/issues/72 for future SMB2 support.

# 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.

# due to SO_KEEPALIVE and helps with FMV audio stutter.
