My Windows 7, with Synology drivers installed when one installs Synology Assistant, sometimes sees the NAS and sometimes it doesn't (Windows Explorer in Network).

Installed 3 more proggies to see Linux files - the same thing occasionally occurs...

 

My E2 machines sometimes fail to kick-start Synology NAS from hibernation.

 

I guess this may be the issue, at least sometimes...

Everybody has that on Windows.  Did not find a good solution yet.  Except I run now a batch file on Windows start-up (1 minute delay).via task Scheduler

net use R: /Delete
net use T: /Delete
net use V: /Delete
net use W: /Delete
net use Y: /Delete
net use Z: /Delete

net use R: \\WDW\Backup /user:username password
net use V: \\WDW\EPG /user:username password
net use W: \\ET6X00\Root
net use Y: \\ET9X00\Root
net use Z: \\WDW\Movie /user:username password

In my experience many problems that I have encountered with connectivity are due to WIFI or cheap NIC's. So I prefer Intel NIC's and steer clear from any Realtek. With the Synology (DS215+) I have never been able to determine the vendor, the only thing I found was the driver: al_eth with version: 0.2, but that didn't help me

With SMB/CIFS, most of the misery comes from the fact that a lot still relies on the old NetBIOS broadcasts and workgroup browser mechanisms (from Windows for Workgroups 3.11 days!), while Microsoft has abandoned that in favour of Dynamic DNS services (where all others have moved to mDNS), and recent Windows versions have it disabled by default.

If your network relies on NetBIOS, it's misconfigured.

 

I do even have neither NetBIOS nor CIFS, only SMB:

disable netbios = Yes
smb ports = 445

 

root@quadbox ~ # ps | grep mbd | grep -v grep
root       642     1  0 14:06 ?        00:00:00 /usr/sbin/smbd
root       645   642  0 14:06 ?        00:00:00 /usr/sbin/smbd

root     11838   642  0 15:12 ?        00:00:00 /usr/sbin/smbd

... no nmbd running ...

Agreed, NetBIOS is ancient.

One of the reasons why I do not understand what the PLi recipe for Samba is that much crippled for.
Samba 4.4.x has about 20 MB ... was it really necessary to save 48 kiloBytes by ripping out testparm and smbstatus?

If you look at the Debian startup scripts for Samba, you will notice that testparm is required to know before-hand if NetBIOS is really wanted ... if not, nmbd doesn't get started.
"disable netbios = Yes" alone inside smb.conf does nothing, you actually have to parse smb.conf before and skip starting nmbd if netbios should be disabled.

Stolen right-away from Debian (Only slightly modified for different logging):

start-stop-daemon --start --quiet --exec $smbd
    NMBD_DISABLED=`testparm -s --parameter-name='disable netbios' 2>/dev/null || true`
    if [ "$NMBD_DISABLED" != "Yes" ]; then
      echo -n " nmbd"
      start-stop-daemon --start --quiet --exec $nmbd
    fi

wsdd also needs testparm, else it would have to make wild guesses about hostname and workgroup (or include a 50 kB parser for smb.conf and its includes ) ...

I do not know, how it is in new samba version, but I am using "disable netbios = yes" in "global". Without it disks in all my mounted synology (using cif + autofs) after sleep begin wakeup. Did not try with new version...

[WanWizard]

I'm not sure there was a concious effort to strip those, I think it was more a matter of "they weren't in 3, lets not add them in 4". So this needs to be looked at too.

 

@ims,

 

Your problem is on the Syno side, the Synology OS has the very annoying habbit of placing it's data directories in volume1 instead of in flash, causing this behaviour (it writes netbios updates and log entries). I have hacked it to use a USB SSD disk as storage for all these directories, and for everything I've installed manually (webservers, proxy, DNS, etc).
