DESCRIPTION

       This  program  is  used  to  mount  volumes  of  the  specified NetWare
       Fileserver under the specified mount point.

       ncpfs is a linux filesystem which understands the NCP protocol. This is
       the  protocol  Novell  NetWare  clients use to talk to NetWare servers.
       ncpfs was inspired by lwared, a free NetWare emulator for Linux written
       by  Ales  Dryak.  See  ftp://klokan.sh.cvut.cz/pub/linux  for this very
       interesting program.

       ncpmount, when invoked with all  appropriate  arguments,  attaches  and
       logs  into  specified  server  and mounts all volumes (or one volume or
       subtree) from server under the specified mount  point.   ncpmount  when
       invoked  without  any  arguments specifying the fileserver, user id and
       password checks the file $HOME/.nwclient to find a file server, a  user
       name  and possibly a password to use for the specified mount point. See
       nwclient(5)  for  more  information.  Please  note  that   the   access
       permissions of .nwclient MUST be 600, for security reasons.

OPTIONS

       mount-point
          mount-point  is the directory you want to mount the filesystem over.
          Its function is the the same as for a normal mount command.

          If the real uid of the caller is not root, ncpmount  checks  whether
          the  user is allowed to mount a filesystem on the mount-point. So it
          should be safe to make ncpmount setuid root. The  filesystem  stores
          the  uid  of  the  user  who called ncpmount. So ncpumount can check
          whether the caller is allowed to unmount the filesystem.

       -S server (mount option server= or part before / in  remote-server-and-
       user)
          server is the name of the server you want to use.

       -h
          -h is used to print out a short help text.

       -C (mount option noupcasepasswd)
          By default passwords are converted to uppercase before they are sent
          to the  server  because  most  servers  require  this.  This  option
          disables  this  feature ensuring that passwords are sent without any
          case conversion.

       -n (mount option nopasswd)
          -n must be  specified  for  logins  that  do  not  have  a  password
          configured.   This  option means do not update /etc/mtab if there is
          option -o on command line. You must use -o nopasswd in this case.

       passwdfile=file (only mount option)
          If you want specify password and you do not want store it into world
          readable  /etc/fstab,  you  can use this option.  file then contains
          lines  in  form  SERVER/USER:PASSWORD:other_data   (other_data   are
          currently unused)

       pass-fd=fd (only mount option)
          If you want to pass password in secure way to ncpmount, you can pass
          it through specified fd.

       -P password (mount option passwd=)
          specifies the password to use for the Netware user id.

          If neither -n nor the  -P  nor  the  passwdfile=  nor  the  pass-fd=
          arguments  are  specified  ncpmount will prompt for a password. This
          makes it difficult to use in scripts such as /etc/rc. If you want to
          have  ncpmount work automatically from a script you must include the
          appropriate option and be very careful  to  ensure  that  appopriate
          file  permissions are set for the script that includes your password
          to ensure that others can not read it.

       -U user name (mount option  user=  or  rest  of  remote-server-and-user
       after /)
          Specifies  the  Netware  user  id  to  use  when  logging  in to the
          fileserver. If this option  is  not  specified  then  ncpmount  will
          attempt  to  login to the fileserver using the Linux login id of the
          user invoking ncpmount.

       -m (mount option multiple)
          Normally, ncpmount limits  number  of  connections  from  client  to
          server  to one per unique user name. If you want mount more than one
          connection with same username and server, you must specify -m.

       -u uid, -g gid (mount option uid= and gid=)
          ncpmount does  not  yet  implement  a  scheme  for  mapping  NetWare
          users/groups  to  Linux  users/groups. Linux requires that each file
          has an owner and group id.  With -u and -g  you  can  tell  ncpmount
          which id’s it should assign to the files in the mounted directory.

          The defaults for these values are the current uid and gid.

       -c user name (mount option owner=)
          -c  names  the  user who is the owner of the connection, where owner
          does not refer to file ownership (that "owner"  is  set  by  the  -u
          argument),  but  the  owner of the mount, ie: who is allowed to call
          ncpumount on this mount. The default owner of the connection and the
          mount  is  the  user  who called ncpmount. This option allows you to
          specify that some other user should be set as the owner.

          In this this  way  it  is  possible  to  mount  a  public  read-only
          directory,  but  to  allow the lp daemon to print on NetWare queues.
          This is possible because only users who have write permissions on  a
          directory may issue ncp requests over a connection. The exception to
          this rule is  the  ’mount  owner’,  who  is  also  granted  ’request
          permission’.

       -f  file  mode,  -d  dir  mode  (mount  option mode= (or filemode=) and
       dirmode=)
          Like -u and -g, these options are used to determine what permissions
          should be assigned files and directories of the mounted volumes. The
          values must be specified as octal numbers. The  default  values  are
          taken  from  the  current  umask, where the file mode is the current
          umask, and the dir mode adds execute permissions where the file mode
          gives read permissions.

          Note  that  these  permissions can differ from the rights the server
          gives to us. If you do not have write permissions on the server, you
          can  very  well  choose  a  file mode that tells that you have. This
          certainly cannot override the restrictions imposed by the server.

       -V volume (mount option volume=)
          There are 2 general ways you  can  mount  a  NetWare  server’s  disk
          space:  Either you can mount all volumes under one directory, or you
          can mount only a single volume.

          When you choose to mount the complete disk space at once,  you  have
          the  advantage  that only one Linux mount point and only one NetWare
          connection is used for all the volumes of this server. Both of these
          are  limited  resources. (Although raising the number of Linux mount
          points is significantly cheaper than raising the number of available
          NetWare connections ;-))

          When  you  specify  to  mount a single volume by using the option -V
          volume, you have the big advantage that nfsd is  able  to  re-export
          this  mounted  directory.  You  must invoke nfsd and mountd with the
          option --re-export to make nfsd re-export ncpfs mounted directories.
          This  uses  one  Linux  mount  point  and one NetWare connection per
          mounted volume. Maybe sometime in the future I will make it possible
          to  mount  all  volumes  on  different  mount points, using only one
          connection.

       -t time_out (mount option timeo= or timeout=)
          With -t you can adjust the time ncpfs waits for the server to answer
          a  request  it  sent. Use the option to raise the timeout value when
          your ncpfs connections seem to be unstable although your servers are
          well up. This can happen when you have very busy servers, or servers
          that are very far away.

          time_out is specified in 1/100s, the current default value is 60.

       -r retry_count (mount option retry=)
          As -t, -r can be used to tune the ncpfs connection  to  the  server.
          With  retry_count  you can specify how many times ncpfs will attempt
          to send a packet to the server before it decides the  connection  is
          dead. The current default value is 5.

          Currently  ncpfs  is  not  too  clever  when trying to find out that
          connections are dead. If anybody knows how to do that correctly,  as
          it is done by commercial workstations, please tell me.

       -y iocharset (mount option iocharset=)
          You  can  specify  character  translation rules for converting names
          from unicode to your desktop (it works together with -p).  iocharset
          is charset name, for example iso8859-1.

       -p codepage (mount option codepage=)
          You  can  specify  character  translation rules for converting names
          from Netware encoding  to  unicode  (it  works  together  with  -y).
          codepage is codepage name, for example cp437.

       -b (mount option bindery)
          If  you  are  connecting  to  NetWare 4 or NetWare 5 through bindery
          emulation instead of NDS, you must specify this option.

       -i level (mount option signature=level)
          Enables packet signing. level is from 0 to 3:  0  means  disable,  1
          means  sign if server needs it, 2 means sign if server allows it and
          3 means sign packets always.

       -v
          Print ncpfs version number. It has another meaning (verbose) if  you
          specify  -o  on command line. If you are interested in version, type
          ncpmount -v without another options.

       -A dns name (mount option ipserver=dns name)
          When you are mounting volumes from NetWare 5 server  over  UDP,  you
          must  specify  dns name of server here and logical server name in -S
          (or in server=). This name is used to switch ncpmount into UDP  mode
          and  to  specify server to connect. Currently, DNS is only supported
          IP name resolution protocol. There is currently no support for  SLP.

       -N ignored namespace (mount option nonfs and nolong)
          ncpfs  supports  NFS,  LONG  (OS/2)  and  DOS  namespace  on NetWare
          volumes. If you do not want to use NFS or LONG namespace (because of
          bugs  in  (server)  code  or  for  backward compatibility), you must
          specify these ignored namespaces in mount parameters.

       -2
          If you have unusual ncpfs code in kernel and ncpmount is not able to
          autodetect  it,  use  this  option.  It  switches  ncpmount to ncpfs
          interface version 2. This interface was used in 2.0.x kernels,  does
          not  support  NCP/UDP, does not have NDS authentication info storage
          and uses only 16bit uid/gid.

       -3
          If you have unusual ncpfs code in kernel and ncpmount is not able to
          autodetect  it,  use  this  option.  It  switches  ncpmount to ncpfs
          interface version 3. This interface was used in kernels from  2.1.30
          to  2.3.40  (laters 2.3.x and 2.4.x still supports this interface to
          make transition easier). This interface supports NCP/UDP, does  have
          NDS  authentication  info  storage  (if  you  uncomment it in kernel
          sources) and uses 16bit uid/gid.

       -4
          If you have unusual ncpfs code in kernel and ncpmount is not able to
          autodetect  it,  use  this  option.  It  switches  ncpmount to ncpfs
          interface version 4. This interface is used in kernels after 2.3.40.
          This  interface  supports NCP/UDP, does have NDS authentication info
          storage and uses 32bit uid/gid.

       -s (mount option strong)
          Normally, files marked read-only  cannot  be  removed  from  NetWare
          volume because of they are marked Delete Inhibit and Rename Inhibit.
          If you want to remove these files by simple unlink, you should mount
          volume with this option.

       mount option nostrong
          Refuse  to remove read-only files. If you want remove such file, you
          must first remove read-only attribute. It is  standard  behavior  of
          ncpfs.

       mount option symlinks
          Use  special,  normally  unused,  attributes combinations to express
          symlinks, executable attributes and files readable by world.

       mount option nosymlinks
          Do not allow special meaning of ’shareable’  attribute.  This  is  a
          default.

       mount option ipx
          Use  IPX  for  connection  to  server. Default if no ipserver option
          specified on cmdline.

       mount option udp
          Use UDP for connection to server. Not available  in  2.0.x  kernels.
          Default if ipserver is used.

       mount option tcp
          Use  TCP  for  connection  to  server. Available only with 2.4.0 and
          later kernels.

       mount option nfsextras
          Use the meta-data provided by the  NFS  namespace  to  allow  files’
          modes to be changed, and to allow the creation of symlinks and named
          pipes.  This adds significant overhead to fetching file information.

       mount option nonfsextras
          Do not make use of meta-data provided by the NFS namespace.  This is
          the default.

ENVIRONMENT VARIABLES

       USER / LOGNAME
          The variables USER or LOGNAME may contain the username of the person
          using  the  client.   USER is tried first. If it’s empty, LOGNAME is
          tried.

DIAGNOSTICS

       Most diagnostics issued  by  ncpfs  are  logged  by  syslogd.  Normally
       nothing is printed, only error situations are logged there.

EXAMPLES

       If  you  want  to  mount volume SYS as user DOWNLOAD from server MIRROR
       into directory /home/pub/mirror, with  files  owner  mirror.mirror  and
       file mode -rw-r--r--, you can add

       MIRROR/DOWNLOAD                   /home/pub/mirror                  ncp
       defaults,mode=644,uid=mirror,gid=mirror,owner=root,volume=SYS,nopasswd,multiple

       into  /etc/fstab.  You should always specify multiple in mount options,
       otherwise there can be only one connection to server with same name.

NOTES

       IPX
          You must configure the IPX subsystem before ncpmount will work.   It
          is  especially  important  that  there  is  a  route to the internal
          network of your server.

       IP
          You must specify both -S logical_name and -A dns_name.  logical_name
          is  used  for  searching .nwclient, other configuration files and is
          logged into /etc/mtab, dns_name is used for connecting to server. In
          future, logical_name will be read from server.
