1.1 – attributes
CHARACTERISTICS Clerk Timeout Specifies the default timeout of client interface calls. If no response is received in the specified time, an error message will be generated. The default is 60 seconds. Default Namespace Contains the name of the clerk's default namespace. Solicit Holddown Specifies the time (in seconds) to wait after initialization before soliciting advertisements from servers. The default is 15 seconds. UID Uniquely identifies the entity. Version Specifies the version of the DECdns architecture implemented by this clerk. COUNTERS Authentication Failures Specifies the number of times a requesting principal failed authentication procedures. Cache Bypasses Specifies the number of requests to read attributes for which the clerk was specifically directed by the requesting application to bypass its own cache. Instead, a server is contacted to get the requested information. This counter does not account for requests that the clerk is unable to satisfy from the cache or for requests to look up names or enumerate the contents of directories. Cache Hits Specifies the total number of read requests directed to this clerk that were satisfied entirely by the information contained in its own cache. This figure accounts only for requests to read attribute values and does not include requests to look up names or enumerate the contents of directories. Creation Time Specifies the time at which this entity was created. Incompatible Protocol Errors Specifies the number of times this clerk received a response to one of its own requests from a server running a protocol version of DECdns software that was incompatible with the protocol version of DECdns software the clerk was running. Clerk requests directed to servers running incompatible protocol versions do not complete. Miscellaneous Operations Specifies the number of operations other than read and write (that is, skulks, enumerating contents of directories, and so on) performed by this clerk. Read Operations Specifies the number of lookup operations performed by this clerk. This counter accounts only for requests to read attributes and does not include name lookups or enumerations of multiple names. Write Operations Specifies how many requests to modify data were processed by this clerk. STATUS ATTRIBUTES State Specifies the state of the DECdns clerk. Broken The DECdns clerk has a fatal error condition. Initial The DECdns clerk is in the process of initializing. Off The DECdns clerk is not available. On The DECdns clerk is running and available. Shut The DECdns clerk is in the process of an orderly shutdown. PRIVILEGES REQUIRED You must have the NET$EXAMINE rights identifier on a VMS system. No special privileges are required on an ULTRIX system.

Enter one or more of the following attribute specifiers: all [attributes] all counters all identifiers all status Ambiguous Creation Time Explicit Creation Name Nickname NSCTS prepositional-phrase A phrase that affects the content of command output.

No special privileges are required on an ULTRIX system.
1.3.1 – attributes
Every DECdns entity has attributes, which are pieces or sets of data associated with that entity. Characteristics are attributes that reflect or affect the operational behavior of an entity. The following are descriptions of valid characteristics: You can use any combination of attribute specifiers in a single command. Use a comma to separate the specifiers. If you do not supply any attribute specifier, the command displays all identifiers and their values. The following are descriptions of valid counters, identifiers, and status attributes: COUNTER Creation Time Specifies the time at which the clerk added this known namespace to its cache. IDENTIFIERS Name Specifies an external, human-readable name by which the namespace can be identified. If the namespace nickname is unique, the Name is the same as the Nickname. Otherwise, the Name is generated by appending _n to the nickname for some value of n that makes it unique. The Ambiguous attribute is then set true for the known namespace. NSCTS Specifies the creation timestamp of the namespace. STATUS ATTRIBUTES Ambiguous Indicates whether the nickname for this namespace is ambiguous; that is, more than one namespace known to this clerk has the same nickname. If true, the namespace nickname is ambiguous. If false, the namespace nickname is unique. Explicit Creation Specifies whether the namespace was created by a create command. If false, the namespace was created by the clerk itself. Nickname The name given to the namespace when it was created.

2.1 – attributes
The following are descriptions of valid characteristics, counters, and status attributes: CHARACTERISTICS Future Skew Specifies the maximum amount of time that a timestamp can vary from local system time at the server node. This characteristic ensures data consistency. Maximum Protocol Version Specifies the maximum version of the DECdns clerk/server protocol that this particular DECdns server supports. Minimum Protocol Version Specifies the minimum version of the DECdns clerk/server protocol that this particular DECdns server supports. UID Uniquely identifies the entity. Version Specifies the version of the architecture implemented by this server. COUNTERS Authentication Failures Specifies the number of times a requesting principal failed authentication procedures. Child Pointer Update Failures Specifies the number of times the server background process was unable to contact all the clearinghouses where a replica of a particular child directory's parent directory is stored, and was therefore unable to apply the child updates that have occurred since the last skulk. This counter increases by one at each occurrence of the Cannot Update Child Pointer event. Creation Time Specifies the time when the DECdns server entity was created. Crucial Replica Removals Backed Out Specifies the number of times a user attempted (from this server) to remove a replica that is crucial to the connectivity of a directory hierarchy. The server background process prevents users from accidentally disconnecting lower-level directories from higher- level directories. When it detects an attempt to remove a crucial replica, it will not execute the command to do so. This counter increases by one at each occurrence of the Crucial Replica event. Incompatible Protocol Errors Accounts for the total number of requests received by this server from a clerk running an incompatible protocol version. A server can communicate with any clerk running the same protocol version, or the version previous to the one it is running. This counter increases by one at each occurrence of the Incompatible Request event. Possible Cycles Specifies the number of times this server followed a chain and encountered an entry already in the chain. For example, a soft link is created that points to a series of links that eventually point back to the first link, or a group which is a member of itself. This counter increases by one at occurrence of the Possible Cycles event. Read Accesses Specifies the number of read operations directed to this DECdns server. Security Failures Specifies the number of times the Security Failures event was generated. This counter is increased whenever a DECdns server has insufficient access rights to a directory or object to perform either a client-requested action or a background operation. Skulks Completed Specifies the number of skulks that were successfully completed by this DECdns server. Skulks Initiated Specifies the number of skulks that were initiated by this DECdns server. Times Lookup Paths Broken Specifies the number of broken connections between clearinghouses on this server and clearinghouses closer to the root. Incoming requests to this server that require a downward lookup in the directory hierarchy may still succeed, but requests requiring lookup in directories closer to the root will fail. This counter increases by one at each occurrence of the Broken Lookup Paths event. Write Accesses Specifies the number of write operations to this DECdns server. STATUS ATTRIBUTES State Specifies the state of the DECdns server. Broken The server has a fatal error condition. Initial The server is initializing. Off The server is not available. On The server is running and available. Shut The server is undergoing an orderly shutdown.
2.2 – example
The following command displays information about the number of completed skulks on the server running on node .sales.orion. dns> show node .sales.orion dns server skulks completed

PRIVILEGE REQUIRED You must have the NET$EXAMINE rights identifier on a VMS system. No special privileges are required on an ULTRIX system.
