                   =========================================
                   Setting Up LAN Post Offices and Mailboxes
                        to Work with the Object Exchange
                   =========================================


The Object Exchange lets you use your existing local area network
to send and receive objects by setting up LAN post offices and 
mailboxes. A LAN post office is a directory to which all users in
your workgroup have access, and a mailboxes are subdirectories 
contained within the post office directory.

To use the Object Exchange with your LAN,

1. Create a post office by selecting a shared area to which all of
   your correspondents have access, and creating a directory. For 
   example, J:\OBEXPOST, where J: is the name of a network drive 
   and OBEXPOST is the name of the post office.

2. Create a mailbox for each user by creating subdirectories under 
   the post office directory. For example, J:\OBEXPOST\USER1 and
   J:\OBESPOST\USER2.

3. When you configure your LAN account in the Object Exchange, enter
   the mailbox name (for example, USER1) in the Mailbox Name edit field,
   and the post office path in the Post Office Path edit field (for 
   example, J:\OBEXPOST).

4. If you want to protect your correspondents' privacy, give the 
   following capabilities to users by assigning the appropriate 
   network rights to each mailbox:

   * Read and delete files for the mailbox owner
   * Scan, create, and write files for all other users
   
   For detailed information on how to assign rights to mailboxes on
   various LANs, see the instructions below.

If you want to experiment on your own, you can create post office
and mailbox directories on your local hard disk, and mail and publish
objects to yourself.

BANYAN 5.0
----------

1. Log in to the Banyan server from a network workstation.

2. When prompted, enter your login name. Enter either your Banyan 
   nickname or your full StreetTalk user name, including your group    
   and organization names.

3. When prompted, enter your password. If you don't have a password, 
   or if this is the first time you've logged on to the first server 
   on a network, press Enter.

4. After the server displays a report on network resources activated 
   during your login, a logical drive designator appears, just like a 
   DOS prompt:

   E:\>

   This is the default login drive for the Banyan network system just 
   after Banyan system installation. If you've set a different default 
   drive in your user profile, the drive you set appears instead.

5. Create a directory for the Object Exchange post office files. For
   example:

   G:
   CD \
   MD PO

6. Create one directory, or mailbox, in the post office directory for 
   each user. For example:

   CD PO
   MD USER1
   MD USER2  etc.

7. Set the access rights list for the post office directory and the user
   directories using SETARL.

   The SETARL program sets the access rights list for a resource. When 
   the program prompts you for the directory name, enter the post office
   directory name (for exmaple, PO). For the post office directory, 
   enable all access rights -- Owner, Group, and World -- for all users.
   For each user mailbox, enable W (rite) and C (reate) only, and set
   the ownership correctly.

Consult the chapter on "Services" in the "Banyan Administrator's Guide" 
for more information about access rights.

Microsoft Lanman 2.1
--------------------

1. Run NET ADMIN for the server to open the Lan Manager Administrator
   window.

2. From the Lan Manager Administrator window, determine what security 
   mode you're running in by selecting Config from the menu and choosing
   Server options. If user security is checked, you're in user security
   mode. If it isn't, you're in share security mode.

   Installation differs depending on the security mode. For user security
   mode, follow these instructions:

   a. Choose View|Shared Resources to open the Shared Resources at 
      \\SERVER dialog box, where SERVER is the name of your server.

   b. Choose Add Share.

   c. When you see a list, select Disk Directory and choose OK.

   d. Type the name you want for your post office in the Sharename 
      text box (for example, PO).

   e. If your applications are installed on drive C, type C:\APPS\PO 
      in the Path text box.  

   f. Choose OK to confirm settings and OK to create directory.

   g. Lan Manager opens the Select a File for Access Permissions 
      dialog box.  With <current directory> selected, press Enter.

   h. You see the Access Permissions for \\SERVER \PO dialog box, where
      SERVER is your server name.  Choose the W (rite) and C (reate)
       permissions.

   i. Move to the Not permitted list and highlight the *USERS group and
      choose Permit to transfer the *USERS group to the Permitted list.  
      You should see *USERS (WC) in the Permitted list. Repeat this
      procedure until all users have WC permission to the post office. 
      Choose OK to confirm your settings.

   j. Lan Manager returns to the Select a File for Access Permissions 
      dialog box.  Choose Done.

   k. Lan Manager returns to the Shared Resources at \\SERVER dialog 
      box, where "SERVER" is your server name.  Choose Add share to 
      add another sharename.  Choose disk directory and OK to confirm. 

   l. In the Share a Directory with the Network dialog box, type the 
      name of a mailbox directory. It is recommended that you use the 
      Lan Manager user name of the individual as the mailbox name for
      ease of system administration.

   m. In the Path text box type

      C:\PO\mailbox name

      where mailbox name is the username of the individual for whom 
      you are creating the mailbox.  Choose OK to confirm your settings
      and OK to confirm that Lan manager should create the directory.

   n. Lan manager opens the Select a File for access Permissions dialog 
      box. With <current directory> selected in the pick list, press 
      Enter.

   o. Lan manager opens the Access Permissions dialog box.  Choose all
      rights (the entire left hand column) and permit ONLY the owner of 
      the mailbox to be on the Permitted list.  Repeat this step for all
      mailboxes you need to create.

   p. Choose OK to confirm your settings. Choose Done at the Select a 
      File for Access Permissions dialog box.  Choose Done at the 
      Shared Resources at \\SERVER dialog box.  Exit from the Lan
      Manager by choosing View|Exit.

AT&T StarGroup 3.5.1
--------------------

These instructions assume a Unix-based server.

 1. From the server, log in as Root.

 2. Create a directory, set the ownership, group and permissions for 
    the post office. Be sure you are in a file system with some
    free space. For example,

    mkdir PO
    chown lmxadmin PO
    chgrp DOS---- PO
    chmod 777 PO

    where PO is the post office name

 3. Create directories for mailboxes, set the ownership, group and     
    permissions. For example, 

    cd PO
    mkdir user1
    chown user1 user1
    chgrp DOS---- user1
    chmod 722 user1

 4. Logout of the server and login to a workstation with administrator 
    rights and run WIN NETADMIN. (you can use the command line to 
    administer StarGroup, consult the "Administering Lan Manager" guide 
    for more information)
 			
 5. Set the focus on the server and then View|Shared Resources.

 6. Choose Add Share.

 7. When you see a list, select Disk Directory, then choose OK to confirm.

 8. Type the name you want for your post office in the Sharename text 
    box (for example, PO).

 9. If your applications are installed on drive C, type C:\APPS\PO in the
    Path text box. Choose OK to confirm settings.

10. Lan Manager opens the File Permissions dialog box. Select Permit All.
    Choose Save to save your settings and Done to exit the File 
    Permissions dialog box.  Choose OK to confirm your settings.
    Exit from the Administrative menu by choosing View|Exit.

11. No sharename needs to be set up for individual mailboxes, as the 
    Unix permissions set on the directory should be sufficient.
