NAME

       cmdebug - Reports the status of a host Cache Manager

SYNOPSIS

       cmdebug -servers <machine> [-port <IP port>]
           [-long] [-refcounts] [-callbacks] [-ctime] [-addrs]
           [-cache] [-cellservdb] [-help]

       cmdebug -s <machine> [-p <IP port>] [-l] [-r] [-cal]
           [-ct] [-a] [-cac] -ce] [-h]

DESCRIPTION

       The cmdebug command displays information about the Cache Manager and client cache status
       on a local or remote AFS client machine.  By default, it displays all locked cache
       entries, but other information can be requested via various options.

CAUTIONS

       The -ctime option is only available with OpenAFS version 1.4.7 and later or version 1.5.28
       or later.  This option can be used to gather information from any version of the Unix
       OpenAFS client, but can only query Windows clients running OpenAFS version 1.5.28 or
       later.

       The -cellservdb option is only available with OpenAFS version 1.4.7 and later or version
       1.5.31 or later.  This option can be used to gather information from any version of the
       Unix OpenAFS client, but can only query Windows clients running OpenAFS version 1.5.31 or
       later.

OPTIONS

       -servers <machine>
           Names the client machine for which to display Cache Manager status.  Provide the
           machine's IP address in dotted decimal format, its fully qualified host name (for
           example, fs1.example.com), or the shortest abbreviated form of its host name that
           distinguishes it from other machines. Successful use of an abbreviated form depends on
           the availability of a name resolution service (such as the Domain Name Service or a
           local host table) at the time the command is issued.

       -port <IP port>
           Identifies the port on which to contact the Cache Manager.  By default, the standard
           port 7001 is used, so this option is very rarely needed.

       -long
           Reports on all lock statuses and all cache entries, rather than only locked cache
           entries.  Do not use this option with -refcounts, -callbacks, -addrs, -cache, or
           -cellservdb.

       -refcounts
           Reports only those cache entries with non-zero reference counts.  Do not use this
           option with -long, -callbacks, -addrs, or -cache.

       -callbacks
           Reports only those cache entries with callbacks.  Do not use this option with -long,
           -refcounts, -addrs, or -cache.

       -ctime
           Causes entry expiration times to be shown in human-readable format. Do not use this
           option with -addrs or -cache.

       -addrs
           Rather than showing any cache entries, displays the interfaces the Cache Manager
           answers on, including their netmasks and MTUs.  This is useful for analyzing clients
           that are multihomed and identifying problems with netmasks or MTU settings.  Do not
           use this option with -long, -refcounts, -callbacks, or -cache.

       -cache
           Rather than showing any cache entries, displays the cache configuration for the client
           machine.  The information displayed is essentially the information that can be
           configured via parameters to afsd.  Do not use this option with -long, -refcounts,
           -callbacks, or -addrs.

       -cellservdb
           Lists all known volume location database records in a CellServDB-compatible format.
           This includes all records in memory, including those from the CellServDB file, DNS SRV
           or AFSDB records, and the fs newcell command. This option could be used to see if a
           client has the latest copy of the CellServDB file. Do not use this option with -long,
           -refcounts, -callbacks, or -cache.

       -help
           Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       Displays all of the locked cache entries on "client1":

           % cmdebug client1

       Displays the cache configuration for "client1.example.com":

           % cmdebug client1.example.com -cache

       Displays all cache entries for "client2.example.com":

           % cmdebug client2.example.com -long
