Verify that the following entries are listed in the Websites list: On the Tools menu In Internet Explorer, click Internet options.Ģ.Ĝlick the Security tab, click the Trusted sites zone, and then click Sites.ģ. CREATE NETDRIVE WINDOWSIf you are authenticated to Office 365 and the issue persists, make sure that an entry for SharePoint is added to the Trusted sites zone in Windows Internet Explorer. Open a document library in Explorer View.ģ. Sign in to the SharePoint Online site by using your Office 365 credentials, and make sure that you click to select the Keep me signed in check box.Ģ. Make sure that you are authenticated to Office 365. it comes bundled with NextCloud.If you encounter issues with the mapped drive disconnecting follow these steps Another alternative is WebDAV (which runs over HTTPS), e.g. CREATE NETDRIVE INSTALLFor example, it really wouldn't be much work to install WireGuard or Tailscale on your laptop.įor remote access you should strongly consider using SFTP which can be hosted using the OpenSSH server, which is usually thought to be resilient enough for use over Internet. In all other cases, the server should only be accessible over a VPN (corporate/mesh/self-hosted, not the commercial ones). In short, it is really not recommended to run SMB directly over Internet you should only do this for Samba servers that host low-risk information, and never for Windows servers. (This is not needed if it's your own personal computer.) Unless you're connecting to Samba as "Guest", you must take special care on public machines: always use net use \\address before opening the share in Explorer, and afterwards net use \\address /del to disconnect. This also means that SMB ports (both the current 445 and the old 139) are often blocked at ISP level so that inbound connections won't even reach your router.Īs most SMB clients do not support connecting to alternate ports and require 445/tcp, this would severely limit your ability to reach the server from outside.įinally, note that Windows machines by default remember the login credentials for the entire local session. RCEs for Windows cannot affect Samba and vice versa, but it is a potential risk nevertheless. Even if you're not running Windows, that won't stop your SMB server from being targetted.įortunately, the majority of exploits are targeted at a specific implementation, and e.g. The Windows SMB service has been a very frequent infection target in the past. Windows Vista/7 use SMBv2.x, which does not support encryption. CREATE NETDRIVE WINDOWS 8.1You can enable it using smb encrypt = in smb.conf, but this will require Windows 8.1 or newer: smb min protocol = SMB3_02 SMBv3 is the first version with encryption support. Older versions of the SMB (CIFS) protocol used by Windows file sharing does not provide data encryption (so anybody with a packet sniffer can monitor your file transfers), and its authentication is not especially strong either. However, if you're trying to do this directly over Internet, there are several things to keep in mind: (Here youraddress is your server's DNS name if you have one, or your external IP address if you don't.) Additionally, you must make sure that your external IP address is pingable from the outside.Īfter this, you'll be able to access the shares by entering \\youraddress in Explorer's address bar or in Start - Run. With Samba, you would have to expose TCP port 445 to the outside – usually this involves configuring "port forwarding" in your router.
