- files to each other, and also chat to each other without the need
- of a server. DCC Sending is used anywhere you send files over IRC,
- and DCC Chat is most commonly used by Eggdrop bots. If you are
- using NAT, this extension will enable you to send files and initiate
- chats. Note that you do NOT need this extension to get files or
- have others initiate chats, or everything else in IRC.

-config IP_NF_NETBIOS_NS
- tristate "NetBIOS name service protocol support (EXPERIMENTAL)"
- depends on IP_NF_CONNTRACK && EXPERIMENTAL
- help
- NetBIOS name service requests are sent as broadcast messages from an
- unprivileged port and responded to with unicast messages to the
- same port. This make them hard to firewall properly because connection
- tracking doesn't deal with broadcasts. This helper tracks locally
- originating NetBIOS name service requests and the corresponding
- responses. It relies on correct IP address configuration, specifically
- netmask and broadcast address. When properly configured, the output
- of "ip address show" should look similar to this:
-
- $ ip -4 address show eth0
- 4: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
