This document describes how to map a Unix network drive from a Windows
machine which is located somewhere outside the local CS subnet, or
which is not a member of the CS-WIN domain, for instance a laptop,
or your machine at home.  For information on mapping a Unix drive
from a machine inside the department, see

  http://www.cs.colostate.edu/~info/faq.html

Off-site machines are not trusted within the cs-win domain, hence they
must use explicit password-based authentication, via a Samba workgroup
server, namely "unix-pw" (which belongs to workgroup cs-offsite).
Before you configure your machine to use this server, you'll need to
contact the CS Department systems staff (sna@cs.colostate.edu) and have
them set up a cs-offsite samba password for your login on this server.

  Note: the cs-offsite samba password is independent of either your
  Unix or cs-win passwords, but like them, it must be changed and
  set to a secure value in order to protect your data.  You may
  set all three passwords to the same value if you'd like.

  Note: please don't attempt to use this mechanism over a modem line.
  The performance is so bad, that it is not worth the effort it takes
  to set it up.

Once you receive your cs-offsite samba password, you can proceed with
the following steps: 

0. Log onto acushla.cs.colostate.edu and run the following command:

	/usr/local/bin/smbpw 

   This will prompt you to change your cs-offsite samba password.

1. Mapping a network drive uses the NetBIOS protocol.  For security reasons,
   NetBIOS traffic is blocked at the campus router.  When connecting from
   off campus, you'll therefore need to use a Virtual Private Network (VPN)
   to tunnel the NetBIOS packets through the router.  For information
   on setting up a VPN, see http://www.colostate.edu/acns/vpn/.  The
   remaining steps assume you are already connected through a VPN tunnel. 

2. Log in to your Windows machine with Administrator privileges.

3. Make sure you have enabled NetBIOS over TCP/IP.

   In Control Panel, click on "Network Connections."  Right-click on
   "Local Area Connection," and select Properties.  Select "Internet
   Protocol (TCP/IP)" and click "Properties," then "Advanced.
   Select "WINS" and make sure "NetBIOS" is enabled.

4. Note that cs-offsite samba no longer requires enabling plain-text passwords
   in your registry settings.  WARNING: If you have enabled plain-text
   passwords in the past, please undo those settings at this time.

5. Add unix-pw to your lmhosts file: 
	You will probably find it at:
	c:/windows/system32/drivers/etc
	
   Use the Windows search tool to locate the lmhosts file on your system.

     Note: in Windows 9X the file may not exist.  If it doesn't,
     create it under C:\Windows.)

   Write this line in the file and then save it:

   129.82.47.50	unix-pw   #PRE

   After you save the file, type:

   nbtstat -R

   Now do nbtstat -c and see if unix-pw shows up in the listing. It should.

6. Now you should be able to map your drive.

   Right click on Network neighborhood and select Map network drive. Type
   in \\unix-pw\LOGIN where LOGIN is your login-name and hit OK.  It will
   prompt you for a password. Put your cs-offsite Samba password there.

7. If it still doesn't like your password, reboot the computer and if you did
   everything correctly you should have no problem anymore.
