Is there a technote available that describes how to access resources of a Windows95 computer from QNX 4 using SmbFsys? |
| Solution |
Introduction
There are many cases when it is handy to access resources on another
computer connected to the network. Now it is possible with QNX to
access resources on a Windows 95 computer. These detailed step-by-step
instructions will help you to configure the systems to do this. You
will set up the sharing access permissions on the Windows 95 system so
its resources can be accessed and run SMBfsys to mount the remote
Windows 95 resources for the QNX computer.
You need:
1. QNX and Windows 95 computers connected on the same network.
2. For the QNX computer, QNX version 4.23A or later and TCP/IP 4.23A
or later.
3. The other computer should have Windows 95 installed.
4. This document does not discuss installation and configuration of
TCP/IP, which must be already installed and configured on both
computers.
INSTRUCTIONS:
Set Sharing Permissions For The Windows 95 Resources:
If you already share the resources with other Windows 95 computers,
most of this will be already done. Follow these instructions to verify
the names and passwords.
1. Select Control Panel, Network, Configuration, File & Print
Sharing.
2. Put a check mark in both the files and printers boxes as desired
and click OK.
3. Select TCP/IP->Ethernet Adapter with the mouse, then click
Properties.
4. Make a note of the IP Address of the computer, then click Cancel.
5. Select the Network tab Access Control. Choose the access control
method you desire.
6. Select the Network tab Identification.
7. Enter a Computer Name and make a note of it (The Workgroup is not
used by the QNX connection, but should probably be changed to
something other than WORKGROUP, to make it more difficult for
others to access the computer via the Internet, if connected.)
8. Click OK to close the Network dialog.
9. If you have made any changes, you will need to reboot now.
10. Open My Computer.
11. Position the mouse over Drive C and click the right mouse button.
12. Select Sharing.
13. Choose Share As.
14. Enter a name into Share Name and make a note of it.
15. Select Read-Only or Full Access as desired and enter a password.
16. Make a note of the password too.
17. If you wish to access the CD-ROM drive, repeat the same procedure
for it.
18. Click OK.
19. If you wish to access printers, double-click the Printers icon to
open it.
20. Repeat the procedure for the printers you wish to access.
21. Unless you want to, it is not necessary to protect the printer
with a password.
Check The TCP/IP Connectivity:
If TCP/IP is incorrectly configured, the following instructions will
not work. On the Windows 95 computer, go to an MS-DOS command prompt
and type:
ping <ip_address_of_QNX_computer>
You should get messages of Reply from, including a time in ms. Press
Control-C to stop. On the QNX computer, type:
ping <ip_address_of_Windows95_computer>
You should see similar messages. Press Control-C to stop. If you
received error messages, such as Request timed out, you will need to
properly configure the TCP/IP on one or both machines before you
continue.
Mount The Windows 95 Resources On The QNX Computer:
As root, create a script to execute the following commands. Items in
triangle brackets should be substituted with the actual values noted
when the Windows 95 computer was configured. Do not type the triangle
brackets. Do not key in the comments on the right. You can create the
script with a text editor. It may be most convenient to do this in a
directory that is included in the search $PATH.
#! /bin/sh This should be the first line of each scrip
t
# Mount Windows 95 Resources
SMBfsys -d20 & -d is idle disconnect time in minutes
sleep 1
user_smb <windows_network_login_name> < windows_network_login_password>
mount_smb -mu //<comp_name>:<ip_address>/<disk_c_name> /w95diskc <disk_c_pass
wd>
mount_smb -mu //<comp_name>:<ip_address>/<cdrom_name> /w95cdrom <cdrom_passwd
>
mount_smb -p //<comp_name>:<ip_address>/<prt_name> /dev/w95prt <prt_passwd>
For an actual example, assume the identification name of the computer
is GATES and its IP Address is 198.102.96.39. Its drive C share name
is DISKC and password is cpass and it will be mounted as directory
/diskc. Its CD-ROM share name is CDROM, no password (blank), which
will be mounted as /cdrom. Its printer share name is HP6P and has no
password. It will be mounted as /dev/hp6p. The Windows Network Login
name is bill and his password is rich. So the example script, called
mount_w95 would be:
#! /bin/sh
# Mount Windows 95 Resources
SMBfsys -d20 &
sleep 1
user_smb bill rich
mount_smb -mu //GATES:198.102.96.39/DISKC /diskc cpass
mount_smb -mu //GATES:198.102.96.39/CDROM /cdrom
mount_smb -p //GATES:198.102.96.39/HP6P /dev/hp6p
For testing, add a line in the script after the /bin/sh line:
set -x
This will display each line of the script as it executes. Save the
file and exit. The permissions of the text file need to be changed so
that it can be executed as a command. Type:
chmod 700 mount_w95
This script must be run by root.
Run your script. At this point you can type ls /diskc and see a
directory listing of the root directory of drive C of the Windows 95
computer. If everything works as expected, remove the set -x line from
the script. If you wish to set access on the per QNX user basis,
remove the user_smb line from the script and have each user run it
individually. You could add it to their $HOME/.profile. If a password
is not included, the user will be prompted for it.
You will likely want to modify the QNX spooler to copy data to the new
device. Depending on the printer and the application that creates the
print data, you may want to use a control program to append a form
feed to eject the page at the end.
