           knfs -host <host name> [-id <user ID (decimal)>]
               [-sysname <host's '@sys' value>] [-unlog] [-tokens]
           knfs -ho <host name> [-i <user ID (decimal)>]
               [-s <host's '@sys' value>] [-u] [-t] [-he]


           The knfs command creates an AFS credential structure on the local
           machine, identifying it by a process authentication group (PAG) number
           associated with the NFS client machine named by the -hostname argument
           and by default with a local UID on the NFS client machine that matches
           the issuer's local UID on the local machine. It places in the
           credential structure the AFS tokens that the issuer has previously
           obtained (by logging onto the local machine if an AFS-modified login
           utility is installed, by issuing the klog command, or both). To
           associate the credential structure with an NFS UID that does not match
           the issuer's local UID, use the -id argument.
           Issue this command only on the NFS(R)/AFS translator machine that is
           serving the NFS client machine, after obtaining AFS tokens on the
           translator machine for every cell to which authenticated access is
           required. The Cache Manager on the translator machine uses the tokens
           to obtain authenticated AFS access for the designated user working on
           the NFS client machine. This command is not effective if issued on an
           NFS client machine.
           To enable the user on the NFS client machine to issue AFS commands, use
           the -sysname argument to specify the NFS client machine's system type,
           which can differ from the translator machine's. The NFS client machine
           must be a system type for which AFS is supported.
           The -unlog flag discards the tokens in the credential structure, but
           does not destroy the credential structure itself. The Cache Manager on
           the translator machine retains the credential structure until the next
           reboot, and uses it each time the issuer accesses AFS through the
           translator machine. The credential structure only has tokens in it if
           the user reissues the knfs command on the translator machine each time
           the user logs into the NFS client machine.
           To display the tokens associated with the designated user on the NFS
           client machine, include the -tokens flag.
           Users working on NFS client machines of system types for which AFS
           binaries are available can use the klog command rather than the knfs


           If the translator machine's administrator has enabled UID checking by
           issuing the fs exportafs command with the -uidcheck on argument, it is
           not possible to use the -id argument to assign the tokens to an NFS UID
               Names the NFS client machine on which the issuer is to work.
               Providing a fully-qualified hostname is best, but abbreviated forms
               are possibly acceptable depending on the state of the cell's name
               server at the time the command is issued.
           -id <user ID (decimal)>
               Specifies the local UID on the NFS client to which to assign the
               tokens. The NFS client identifies file requests by the NFS UID, so
               creating the association enables the Cache Manager on the
               translator machine to use the appropriate tokens when filling the
               requests. If this argument is omitted, the command interpreter uses
               an NFS UID that matches the issuer's local UID on the translator
               machine (as returned by the getuid() function).
           -sysname <host's '@sys' value>
               Specifies the value that the local (translator) machine's remote
               executor daemon substitutes for the @sys variable in pathnames when
               executing AFS commands issued on the NFS client machine (which must
               be a supported system type). If the NFS user's PATH environment
               variable uses the @sys variable in the pathnames for directories
               that house AFS binaries (as recommended), then setting this
               argument enables NFS users to issue AFS commands by leading the
               remote executor daemon to access the AFS binaries appropriate to
               the NFS client machine even if its system type differs from the
               translator machine's.
               Discards the tokens stored in the credential structure identified
               by the PAG associated with the -host argument and, optionally, the
               -id argument.
               Displays the AFS tokens assigned to the designated user on the
               indicated NFS client machine.
               Prints the online help for this command. All other valid options
               are ignored.


           The following error message indicates that UID checking is enabled on
           the translator machine and that the value provided for the -id argument
           differs from the issuer's local UID.
              knfs: Translator in 'passwd sync' mode; remote uid must be the same as
              local uid


           The following example illustrates a typical use of this command. The
           issuer "smith" is working on the machine "" and has user
           ID 1020 on that machine. The translator machine "" uses an
           AFS-modified login utility, so "smith" obtains tokens for the ABC
              % knfs 1020
              % exit
           The following example shows user smith again connecting to the machine
           "tx4" via the telnet program and discarding the tokens.
              % telnet
              . . .
              login: smith
              AFS(R) login
              % knfs 1020 -unlog
              % exit
