were seeing. I've turned on the DHCP option on our DHCP server to disable NeTBIOS. I also have a SCCM configuration baseline to set the NIC properties on our workstations to disable NeTBIOS. But, I'm still see UDP traffic on port 137 and 138 being broadcast out from our workstation...
ip udp-helper port disable命令用来删除已配置的UDP Helper中继转发的端口号。 undo ip udp-helper port disable命令用来配置UDP Helper中继转发的端口号,目的端口为该端口的UDP广播报文会被转发。 缺省情况下,交换模块默认对6个UDP端口号37、49、53、69、137、138的广播报文进行中继转发。
The undo ip udp-helper port disable command specifies the UDP ports to which UDP broadcast packets are relayed. By default, the switch relays broadcast packets destined for ports 37, 49, 53, 69, 137, and 138. Format ip udp-helper port disable { port-number | dns | netbios-ds | ...
大多数对这个端口的扫描是基于UDP的,但是基于TCP的mountd有所增加(mountd同时运行于两个端口)。记住mountd可运行于任何端口(到底是哪个端口,需要在端口111做portmap查询),只是Linux默认端口是635,就像NFS通常运行于2049端口。 端口:636 服务:LDAP 说明:SSL(Secure Sockets layer) 端口:666 服务:Doom Id Software ...
Bonjour runs mDNSResponder which listens on port 5353 and implements Multicast DNS and DNS service discovery. There is also a NetBIOS daemon that interacts with NetBIOS networks and interacts with mDNSResponder via ports 137/138. These help it to detect networked printers, PCs on the network, ...
I have other ports, TCP and UDP that I have blocked successfully, and iptables shows the ports listed with a DROP directive, but they contiunue to scan as `open|filtered`. `DROP udp -- anywhere anywhere multiport sports netbios-ns,netbios-dgm DROP tcp -- anywhere anywhere multiport dpo...
说明:其中137、138是UDP端口,当通过网上邻居传输文件时用这个端口。而139端口:通过这个端口进入的连接试图获得NetBIOS/SMB服务。这个协议被用于windows文件和打印机共享和SAMBA。还有WINS Regisrtation也用它。 端口:143 服务:Interim Mail Access Protocol v2 说明:和POP3的安全问题一样,许多IMAP服务器存在有缓冲区...
With UDP, client port selection depends on the application and may be incremental, fixed to a nonsensical value, or fixed equal to the server port. 端口描述状态 1025/tcp NFS-or-IIS 非官方 1026/tcp Often utilized by Microsoft DCOM services 非官方 1029/tcp Often utilized by Microsoft DCOM ...
port-number:需要中继转发的UDP端口号,取值范围为1～65535(不支持67和68)。 dns:对DNS的数据报文进行中继转发,对应的UDP端口号为53。 netbios-ds:对NetBIOS数据报服务的数据报文进行中继转发,对应的UDP端口号为138。 netbios-ns:对NetBIOS名字服务的数据报文进行中继转发,对应的UDP端口号为137。
