Samba+FreeBSD+OSX Finder

Tried to run Samba44 on FreeBSD to share files on the local network with OSX machines. Took me a while but I finally figured out that in order to get rid of the infamous ERROR -36 from the Mac Finder, you have to disable sendfile with:

use sendfile = no

As a matter of fact, let me post a complete working example of smb4.conf that works between my FreeBSD-hosted Samba and my Mac (Yosemite):

[global]
# Following line is useful on Linux, not on FreeBSD apparently
# socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=131072 SO_SNDBUF=131072
realm=*
max protocol=SMB3
winbind enum groups=yes
winbind enum users=yes
large readwrite = yes
max xmit=32768
min receivefile size=2048
use sendfile = no
aio read size = 2048
aio write size = 2048
write cache size = 1024000
read raw = yes
write raw = yes
getwd cache = yes
unix charset = UTF-8
oplocks = yes
workgroup = HOME
server string = PO
security = user
map to guest = Bad User
log level = 5
log file = /var/log/samba4/samba.log
max log size = 50
interfaces = 192.168.0.0/16
hosts allow = 127.0.0.1 192.168.0.0/16
hosts deny  = 0.0.0.0/0
#dns proxy = no
# I do not want Samba to serve printers, thanks
printing = bsd
printcap name = /dev/null
guest ok = yes
guest account = nobody
load printers = no
printing = bsd
printcap name = /dev/null
disable spoolss = yes
ea support = no

# Share the directory in /data/share as 'share'
[share]
path = /data/share
public = yes
guest ok = yes
writable = yes
browsable = yes
create mask = 0777
directory mask = 0777
force user = nobody
follow symlinks = yes

In addition, OSX does not support guest access to an SMB server. The simplest solution I found was to set up a user called ‘nobody’ without password:

smbpasswd nobody
-> Press ENTER twice to set no password

And then access your share by pointing your Mac Finder to smb://nobody@HOST/share and click Connect.

Note to self: never ever install a Samba server after 7pm if you want a full night sleep.
