SMB v2 support

[Shira]

@substring what I need is to load the roms from my PC shares, so in this case the problem is with the recalbox smb client

[Substring]

@shira then please read the wiki, this has absolutely nothing to do with the protocol version

[Shira]

@substring it does, if my pc or nas has v1 removed then we need recalbox to be able to access smb v2 shares

[Shira]

# mount.cifs //192.168.0.2/RecalboxRoms /recalbox/share/roms -o username=roms,password=roms
mount error(112): Host is down
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

[Shira]

@substring got it working, we simply have to add "vers=2.0" (or 2.1 / 3.0 /3.02) to the mount commands, i.e:

sharenetwork_smb1=ROMS@192.168.0.2:RecalboxRoms:username=roms,password=roms,vers=2.0
sharenetwork_smb2=SAVES@192.168.0.2:RecalboxSaves:username=roms,password=roms,vers=2.0

@shira great job !
Still, it's a shame it can't properly "autodetect" the protocol version

[toniosj]

@shira Do you use Windows10? Does dosbox work with shared folder from Windows 10?

[Shira]

@toniosj Yes Win10. Dosbox?

[toniosj]

@shira Since 17.12.2, dosbox doesnt detect my roms folder shared from Windows. All rest emulators work perfectly. And you?

[Shira]

@toniosj hm I don't have any dosbox games to test

[toniosj]

@shira I've send you a chat.
