- The ////eeeettttcccc////sssseeeeccccuuuurrrreeeennnneeeettttssss file lists networks and hosts that may participate in
- the NIS protocol with this host. This file is used by both the NIS
- server library nnnniiiisssssssseeeerrrrvvvv((((7777pppp)))).
-
- This file contains any number of netmask/address pairs, one per line
- separated by white space. The netmask controls which bits in an address
- are contained in the match. It should contain all ones followed by all
- zeros in binary. A netmask of 255.255.255.255 (all ones in binary) would
- require an exact match of the address. An example file would be:
-
- 255.255.0.0 128.1.0.0
- 255.255.255.255 128.2.1.1
- 255.255.255.0 128.3.4.0
-
- When the NIS libraries are initially loaded into nsd this file is parsed
- into an internal binary format. When a request from a host is received
- its source address is logically ANDed with the netmask and compared to
- the address. If they are identical then the request is allowed, else a
- message is logged and the request is ignored.
-
- When this file is changed a HUP signal must be sent to the nsd daemon for
- the file to be reparsed. This can be done with the command kkkkiiiillllllllaaaallllllll ----HHHHUUUUPPPP
