KEYSERV(8C)                                                        KEYSERV(8C)



NAME
       keyserv - server for storing public and private keys

SYNOPSIS
       keyserv [ -dkn ]

DESCRIPTION
       keyserv  is  a  daemon  that is used for storing the private encryption
       keys of each user logged into the system.  These  encryption  keys  are
       used  for accessing secure network services such as secure NFS.  When a
       user logs in to the system, the login(1) program uses the  login  pass-
       word  to decrypt the user's encryption key stored in the Network Infor-
       mation Service (NIS), and then gives the decrypted key to  the  keyserv
       daemon to store away.

       Normally,  root's key is read from the file /etc/.rootkey when the dae-
       mon starts up.  This is useful during power-failure reboots when no one
       is  around  to  type  a password, yet you still want the secure network
       services to operate normally.

OPTIONS
       -d     Prohibit the use of the default key.  If this is used then every
              machine and user should have a publickey.  New publickeys cannot
              be created if you do not already have a key.  This can  be  done
              globally  for an entire domain by deleting the nobody entry from
              /etc/publickey on the NIS master.  See chkey(1)

       -k     Remember keylogins across machine reboots.  This is only  needed
              if  at(1) is used to schedule jobs that require secure RPC.  Use
              of this option is not recommended.

       -n     Do not read root's key from /etc/.rootkey.  Instead, prompt  the
              user  for  the password to decrypt root 's key stored in the NIS
              service and then store the decrypted key  in  /etc/.rootkey  for
              future  use.   This  option  is useful if the /etc/.rootkey file
              ever gets out of date or corrupted.

FILES
       /etc/.rootkey       /etc/keystore

NOTES
       The Network Information Service (NIS) was formerly known as Sun  Yellow
       Pages  (YP).   The  functionality of the two remains the same; only the
       name has changed.
