- domain <subcommand>
-
- The domain commands control and show the working of the name to
- Internet address mapping software. JNOS40 has both a network client
- and server. The server will answer queries from data in the domain
- cache, and from information stored in the rom DOMAIN.TXT file.
-
-
-
- domain addserver <hostid> [<timeout>]
-
- Add a domain name server to the list of name servers.
-
- <timeout> is an optional timeout setting in seconds for
- this server. If <timeout> is not included in the command, the
- value defaults to 3 * (tcp_irtt).
-
- Example: domain addserver wg7j.ece.orst.edu
- domain addserver 128.193.48.1
- domain addserver ucsd.edu
-
-
- domain cache <subcommand>
-
- Following commands work on the domain cache. These are resource
- records held in memory. (described in RFC1033/1034)
-
- domain cache clean [<yes | NO>]
-
- Displays or sets the discard of expired resource records.
- Expired records have their time-out value decremented to zero.
- Normally resource records get a default time-out value of 1800
- seconds. After this time they are considered "old" and if
- referenced again the domain name resolver should be inquired
- again. When clean is off (the default), expired records will
- be retained; if no replacement can be obtained from another
- domain name server, these records will continue to be used.
- When clean is on, expired records will be removed from the
- file whenever any new record is added to the file.
- domain cache clean yes
-
-
- domain cache dump
-
- Immediately clears the domain cache
-
-
- domain cache list
-
- This command shows the current content of the in-memory cache
- of resource records.
-
-
- domain cache size [<size>]
-
- (B) Display or set the maximum size of the local in-memory
- domain cache. Default is 5.
- domain cache size 10
-
-
- domain dns [on|off]
-
- (B) Display or toggle the state of the Domain Name Server. If
- on, the system is active as a Domain Name Server. The system will
- then answer queries from other tcp/ip hosts regarding hostname to
- ip-address, and ip-address to hostname translations. For more
- information, see the section SETTING UP THE DOMAIN NAME SYSTEM.
-
-
- domain dropserver <hostid>
-
- Remove a domain name server from the list of name servers. You
- are warned when you delete the last name server.
- domain dropserver ece.orst.edu
-
-
- domain listservers
-
- List the currently configured domain name servers, along with
- statistics on how many queries and replies have been
- exchanged with each one, response times, etc.
-
- domain maxwait [<time-out>]
-
- (B) This sets a time-out value (1 to 255 seconds) to a query or
- domain name server. This is not set for an already defined
- server but will be used for a newly defined name server. Also
- the value is used for domain name lookups (E.g. when a user does
- a telnet to a host with the nodeshell 'T host' command). Note
- that (PC based) name servers can have trouble finding records in
- a large database. Default is 60 seconds.
-
- domain maxwait 10
-
-
- domain retries [<retries>]
-
- (B) The retry value (number) limits the number of queries sent
- out to remote domain name resolvers before giving up and telling
- you that host xyzzy.ampr.org does not exist. The total time lost
- with a query is (retries * time-out * number of domain servers
- defined); i.e., the delay between requesting a hostname to ip-
- address translation and getting the answer can become very long
- if you use many servers, and set the time-outs/retries high !
- Default is 2.
-
- domain retries 1
-
-
- domain subnet [on | off]
-
- This command works in conjunction with 'domain translate' to
- allow or disallow translation of any address ending in 0 or 255.
- On systems which have a lot of subnets, turning off subnet
- translation can result in a considerable speedup when displaying
- routes with 'domain translate on'.
-
-
- domain suffix [<domain suffix> | none]
-
- Display or specify the default domain name suffix to be appended
- to a host name when it contains no periods. For example, if the
- suffix is set to "ampr.org." and the user enters 'telnet ka9q',
- the domain resolver will attempt to find 'ka9q.ampr.org.' If the
- host name being sought contains one or more periods, however, the
- default suffix is NOT applied if the last part of the name is
- less than 5 characters and contains only letters; e.g., 'telnet
- foo.bar' would NOT be turned into 'foo.bar.ampr.org.' 'telnet
- foo.ka9q' will be turned into 'foo.ka9q.ampr.org.' Note that a
- trailing dot (.) is required for the suffix. If the suffix is
- the string 'none' (without trailing period), the current suffix
- is cleared and forgotten. Default is "ampr.org."
- domain suffix ece.orst.edu.
-
-
- domain trace [on| OFF]
-
- (B) Display or set the flag controlling the tracing of domain
- server requests and responses. This only works when console is
- enabled. Default is off.
-
- domain trace on
-
-
- domain translate [on | OFF]
-
- (B) Display or set the flag that controls the translation of ip
- addresses in dot notation into symbolic names. The translation
- process makes heavy use of reverse domain name lookups. Do not
- set this flag unless you have a good and fast connection to a
- domain name server.
-
- domain translate on
-
-
- domain ttl [ttl]
-
- Select a default 'ttl' value to be applied to server responses
- than contain none.
-
-
- domain update [on | off]
-
-
- Controls whether or not domain.txt file is updated with server
- responses.
-
- domain verbose [on | off]
-
- (B) Display or set the flag controlling the return of a full
- name (on) or only the first name (dot delimiter) (off). This is for
- IP address to name translation only. If off, home.wg7j.ampr.org. will
- show as 'home.wg7j', whereas if on it will show as
- 'home.wg7j.ampr.org'
-
- domain verbose off
