What is NetBIOS API?
NetBIOS (/ˈnɛtbaɪɒs/) is an acronym for Network Basic Input/Output System. It provides services related to the session layer of the OSI model allowing applications on separate computers to communicate over a local area network. As strictly an API, NetBIOS is not a networking protocol.
Is NetBIOS used by Linux?
Installing SAMBA on a Linux machine will assign it a NetBIOS name (or, more technically, will make a Linux machine advertise itself in broadcast requests with their NetBIOS name, which is by default their hostname), and that allows Windows machines to find the Linux ones.
Is NetBIOS TCP or UDP?
(This service is often called Windows Internet Name Service (WINS) on the Microsoft Windows system). NetBIOS listens on port 137/TCP and port 137/UDP.
What can you do with NetBIOS?
NetBIOS stands for Network Basic Input Output System. It Allows computer communication over a LAN and allows them to share files and printers. NetBIOS names are used to identify network devices over TCP/IP (Windows).
What is NetBIOS setting?
NetBIOS or Network Basic Input/Output System is an API used in Windows when DNS is not available. Even when it runs, it runs over TCP/IP. It’s a fallback method, and it’s not enabled by default. NetBIOS has its own set of security concerns.
What is NetBIOS ns used for?
Name: | netbios-ns |
---|---|
Purpose: | NetBIOS Name Service |
Description: | UDP NetBIOS name query packets are sent to this port, usually of Windows machines but also of any other system running Samba (SMB), to ask the receiving machine to disclose and return its current set of NetBIOS names. |
Related Ports: | 138, 139, 445 |
What is NetBIOS and SMB?
SMB has always been a network file sharing protocol. As such, SMB requires network ports on a computer or server to enable communication to other systems. NetBIOS is an older transport layer that allows Windows computers to talk to each other on the same network.
Does Samba use NetBIOS?
Samba implements NetBIOS, as does MS Windows NT/200x/XP, by encapsulating it over TCP/IP. NetBIOS-based networking uses broadcast messaging to effect browse list management. When running NetBIOS over TCP/IP, this uses UDP-based messaging.
Is NetBIOS an SMB?
SMB does rely on NetBIOS for communication with devices that do not support direct hosting of SMB over TCP/IP. NetBIOS is completely independent from SMB. It is an API that SMB, and other technologies can use, so NetBIOS has no dependency to SMB.
Is NetBIOS enabled by default?
NetBIOS is a somewhat obsolete broadband protocol. Yet, despite its vulnerabilities, NetBIOS is still enabled by default for network adapters in Windows. Some users might prefer to disable the NetBIOS protocol. This is how users can disable NetBIOS in Windows 10.
Do hackers use NetBIOS?
Firewall: Block ports 135-139 plus 445 in and out. These are used by hackers to steal your info and take control of your pc and after doing so will use NetBIOS to then use your computer to take over another, etc, etc.. Port 137-139 is for Windows Printer and File Sharing but also creates a security risk if unblocked.
Why is NetBIOS still used?
Microsoft Windows still uses it for its name resolution function (often by default), when DNS is not available. Network resiliency and access to resources is a good thing, but keeping NetBIOS enabled for that reason, is not. NetBIOS is used for name resolution and communication on a local network.
