The upserver command initializes the server portion of the Update
Server (the upserver process). In the conventional configuration, its
binary file is located in the /usr/local/libexec/openafs directory on a file server
The upserver command is not normally issued at the command shell prompt
but rather placed into a file server machines /usr/local/etc/openafs/BosConfig
file with the bos create command. If it is ever issued at the command
shell prompt, the issuer must be logged onto a database server machine as
the local superuser root.
The upserver command specifies which of the directories on the local
disk are eligible for distribution in response to requests from the client
portion of the Update Server (the upclient process) running on other
machines. If no directories are specified, the upserver process
distributes the contents of any directory on its local disk.
The upserver process can distribute a directorys contents in encrypted
or unencrypted form. By default, it does not use encryption unless an
upclient process requests it (this default is equivalent to setting the
-clear flag). When the -crypt flag is provided, the upserver
process only fulfills requests for encrypted transfer.
The upclient and upserver processes always mutually authenticate,
whether or not the data they pass is encrypted; they use the key with the
highest key version number in the /usr/local/etc/openafs/server/KeyFile file to
construct a server ticket for mutual authentication.
This command does not use the syntax conventions of the AFS command
suites. Provide the command name and all option names in full.
