LinuxQuestions.org - Problem mounting directory between servers

Hi,

You will need to setup your systems for a 'NFS' Network Filesystem. Look at 'Linux NFS' and 'Linux Networking HOWTO' to get some good online reference.

You should setup the following;

Code:

/etc/hosts    /etc/hosts.deny

/etc/hosts.allow

Code:

excerpt from 'man hosts'

HOSTS(5)                  Linux Programmer's Manual                  HOSTS(5)



NAME

      hosts - The static table lookup for host names



SYNOPSIS

      /etc/hosts



DESCRIPTION

      This  manual  page  describes  the format of the /etc/hosts file.  This

      file is a simple text file that associates IP addresses with hostnames,

      one line per IP address.  For each host a single line should be present

      with the following information:



              IP_address canonical_hostname [aliases...]

Code:

excerpt from 'man nfs';



NFS(5)                                                                  NFS(5)



NAME

      nfs - fstab format and options for the nfs and nfs4 file systems



SYNOPSIS

      /etc/fstab



DESCRIPTION

      NFS  is  an  Internet  Standard protocol created by Sun Microsystems in

      1984. NFS was developed to allow file sharing between systems  residing

      on  a local area network.  The Linux NFS client supports three versions

      of the NFS protocol: NFS version 2 [RFC1094], NFS version 3  [RFC1813],

      and NFS version 4 [RFC3530].



      The  mount(8) command attaches a file system to the system's name space

      hierarchy at a given mount point.  The /etc/fstab  file  describes  how

      mount(8)  should  assemble  a system's file name hierarchy from various

      independent file  systems  (including  file  systems  exported  by  NFS

      servers).  Each  line  in  the /etc/fstab file describes a single file

      system, its mount point, and a set of default mount  options  for  that

      mount point.

      For NFS file system mounts, a line in the /etc/fstab file specifies the

      server name, the path name of the exported server directory  to  mount,

      the  local  directory  that is the mount point, the type of file system

      that is being mounted, and a list of mount options that control the way

      the filesystem is mounted and how the NFS client behaves when accessing

      files on this mount point.  The fifth and sixth fields on each line are

      not  used  by NFS, thus conventionally each contain the digit zero. For

      example:



            server:path    /mountpoint    fstype    option,option,...  0 0



      The server's hostname and export pathname are  separated  by  a  colon,

      while  the  mount options are separated by commas. The remaining fields

      are separated by blanks or tabs.  The  server's  hostname  can  be  an

      unqualified  hostname,  a fully qualified domain name, or a dotted quad

      IPv4 address.  The fstype field contains either "nfs" (for version 2 or

      version  3  NFS  mounts) or "nfs4" (for NFS version 4 mounts).  The nfs

      and nfs4 file system types  share  similar  mount  options,  which  are

      described below.

Don't forget the '/etc/exports'.

Code:

excerpt from 'man exports';



EXPORTS(5)                Linux File Formats Manual                EXPORTS(5)



NAME

      exports - NFS file systems being exported (for Kernel based NFS)



SYNOPSIS

      /etc/exports



DESCRIPTION

      The  file  /etc/exports serves as the access control list for file sys-

      tems which may be exported to NFS clients.  It is used  by  exportfs(8)

      to  give  information  to  mountd(8)  and  to the kernel based NFS file

      server daemon nfsd(8).



      The file format is similar to the SunOS exports file.  Each  line  con-

      tains  an  export  point  and  a  whitespace-separated  list of clients

      allowed to mount the file system at that point. Each listed client  may

      be  immediately  followed  by  a parenthesized, comma-separated list of

      export options for that client. No whitespace is  permitted  between  a

      client and its option list.

Don't forget 'exportfs';

Code:

excerpt from 'man exportfs';



exportfs(8)                                                        exportfs(8)



NAME

      exportfs - maintain list of NFS exported file systems



SYNOPSIS

      /usr/sbin/exportfs [-avi] [-o options,..] [client:/path ..]

      /usr/sbin/exportfs -r [-v]

      /usr/sbin/exportfs [-av] -u [client:/path ..]

      /usr/sbin/exportfs [-v]

      /usr/sbin/exportfs -f



DESCRIPTION

      The  exportfs command is used to maintain the current table of exported

      file systems for NFS. This list  is  kept  in  a  separate  file  named

      /var/lib/nfs/xtab  which  is read by mountd when a remote host requests

      access to mount a file tree, and parts of the list which are active are

      kept in the kernel's export table.



      Normally  this  xtab file is initialized with the list of all file sys-

      tems named in /etc/exports by invoking exportfs -a.
