If rvice is not running, the server will still be accessible, just not discoverable, i.e. It should work for most non-Windows file managers (macOS Finder, various GUI-based file managers on Linux & BSD etc.) Install the avahi package, then enable/start rvice to make the samba server discoverable with Zeroconf. If your network is only composed of machines running Windows 10 or later, consider installing a WSD daemon as well for your server to appear in the "Network" view. However, it is needed to access Samba servers by hostname (e.g. File transfer speed will not be slowed by CPU considerations.Note: nmb.service is not required. So plenty of power to do other tasks while doing VPN. that is old 2005-2006 tech.Īny i3 gen4+ CPU or any i5 or i7 except Generation 1 CPU have special AES encryption hardware that will let them do VPN encryption literally 100 times faster. If practical separate work into downloading a local copy first then operating on local copy before transferring the altered files back to the share.Īs a rule of thumb a dedicated Pentium D with 2GB of RAM can push 10-15Mbps/sec continuously through a VPN. ![]() But mass data exchange for large file transfers or database access could be an issue on machines already near acceptable performance limits. Not really an issue if editing small files by hand. Yup it will use CPU power to encrypt data in a VPN so you need a little extra CPU room while files are being exchanged. Effectively a BIG Hole in the onboard firewalls. Older SMB versions can be a fast way to spread problems from any infected computer across all LAN connected machines. Worse the use of Ports 137, 138, and 139 are mostly linked to older versions of SMB.Įven on supposedly secure LANs, SMBv1 should be disabled if its possible to use SMBv2 or higher. SMBv3 is still quite vulnerable to malware infections or data theft when exposed to anonymous users on Internet or LANs not secured from the public. Port 445 is blocked because despite many security improvements to version 3 of the SMB protocol. Yes SMBv3 uses only port 445 (UDP/TCP) on Windows (and I think the latest SAMBA). WebDAV has more or less turnkey HTTPS file server solutions. HTTPS file transfers and many other better protocols exist to cross the internet. If you want to avoid the technical and its only a few easily anticipated files - store them in DropBox or similar online storage using HTTPS web interface. Run VPN client software to connect to the share-VPN Server machine. Run a VPN server program on the machine with the share. That also solves the blocked port 445 as every port is encrypted and hidden inside the VPN tunnel. At least use VPN tunneling to add security. Sounds like you are using naked SMB (CIFS) over public networks - not good. ![]() I suggest accessing a share and using an IP address (e.g. ![]() Note: Windows 10 is not happy about connecting to an SMB v2 server over port 139, I only needed to connect to SMB v1 servers or SMB v2 servers with port 445 open, so I did not need to disable SMB v2 on the client side. Restart is needed and 'Enable NetBIOS over TCP/IP' must be enabled, obviously. Were missing a few entries, first I had to find out the GUID of my NIC using wmic nicconfig get description,index,TcpipNetbiosOptions,SettingIDĪnd then I had to make sure all the necessary entries are present.Įxport: \Device\LanmanWorkstation_Tcpip_ Turns out that the LanmanWorkstation service registry settings under HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Linkage I had the same problem with a fresh install of Windows 10 (v1709) not attempting to use port 139 when connecting to SMB servers.
