host-name
The name of any host from the /etc/hosts file. AS/400 does not support
the /etc/hosts file as a separate integrated file system file. The /etc/hosts
is built in to AS/400 TCP/IPsupport.
user-name
The name of any user from the /etc/passwd file. AS/400 does not support
the /etc/passwd file concept.
domain-name
The name of any domain.
On AS/400, the following format rules apply to netgroups:
1. All entries are ended by the end of a line.
2. The continuation character ’\’ can be used to extend one entry across multiple
lines when it is the last character in the line.
3. All characters following the pound sign ’#’ are considered comments until the
end of the line.
4. In the triple (host-name,user-name,domain-name) only the host-name is
recognized. Any value supplied for user-name or domain-name will be ignored.
5. Commas ’,’ should be used to separate elements in a list.
6. A blank host-name will not be considered as a wild-card. There is no wild-card
support.
7. Blanks are allowed anywhere except within a netgroup-name or a host-name.
8. Imbedded hexadecimal characters are not allowed.
9. No control-characters are allowed (this includes any characters below ASCII
x020).
10. Entries are not case-sensitive.
11. Triplets(x,y,z) (a,b,c) may be separated by spaces or commas only.
/etc/rpcbtab File
This file is used by the RPC binder (port mapper) daemon. Information for all
daemons is stored in this file, which is used to register daemons upon recovery of
an RPC binder (port mapper) daemon crash.
Note: It is recommended that users never write to or change the /etc/rpcbtab file.
/etc/statd File
This file is used exclusively by the server Network Status Monitor daemon. This file
stores information about any clients that hold byte-range locks on open server files.
When a user starts the NSM daemon after a crash, the NSM daemon contacts all
the clients listed in this file so that the clients can release any locks they hold on
the server.
Note: It is recommended that users never write to or change the /etc/statd file.
