Post SFU Installation Tasks

There are several tasks you should do after you install the SFU software.

1. Before you start using SFU and before you actually install N1GE. please check that user mapping is working correctly by following these steps.

   1. Open an Interix shell locally on the Interix host.

   2. Use the login command to switch to a known user that is not the Administrator.

   3. Verify the access permissions of NFS shares which should be accessible by that user.

   4. Try to access these network resources. If a user cannot access a Network drive, most likely the User Name Mapping is not working correctly.

2. Check users home directories. To enable the automounting of the users home directories use this series of menus:

   Control Panel -> Administrative Tools -> Computer Management -> Users -> Properties -> Profile

   Click on connect to, select a drive letter, and enter the path of the users home directory in UNC notation:\\<server>\<share>\<user home>

   Within the Interix subsystem, you might access all NFS shares through the special directory:/net/<server>/<share>

   You might also create links to these directories to access the shares directly (for example, ln -s /net/myserver/export/share00/home /home).

3. Enable Administrator names on your machines.

   Make sure that the Administrator accounts on all machines which should be enabled as executions hosts for N1GE use the same account name (e.g. Administrator).

   Also make sure that this user has manager privileges in your N1GE cluster. If this is not the case then before the installation of the execution daemon, please add the privileges using this command:qconf -am <Administrator>

4. Set the CLI commands which start an editor. Make sure to set the EDITOR environment variable to vi or your preferred UNIX editor within the Interix subsystem before you start using UNIX commands.

5. Mount NFS shares.

   There are two ways to mount NFS shares to the Interix host:

   • The recommended way is using the auto mount functionality of Interix. All network shares that the Computer Browser service of Windows can find are automatically mounted to the "/net" directory of Interix. Some of them may be listed with "ls /net", some of the may be not, but the are anyway accessible. The syntax of the auto mounts is "/net/<server>/<share>", e.g. "/net/myserver/home". A link to a auto mounted share can be created to make it accessible under exactly the same name as on a Unix host. E.g. "ln -s /net/myserver/home /home" will make the users Unix home directories accessible via "/home/username". Automounted shares are available from boot time on, they are available for all users (who have, in general, the permissions to access these shares) and can't get lost by misconfiguration.

   • Network shares can also be mapped to drive letters. This is done with the command "nfsmount". The syntax is "/usr/sbin/nfsmount -u: \\computername\sharename devicename" e.g. "/usr/sbin/nfsmount -u: \\\\myserver\\home Z:" (All backslashes have to be written two times, because the shell interprets a single backslash as an escape character.) This drive is now accessible via "/def/fs/Z". A link can be created to this drive to have the same path as on a Unix host.

6. Enable Interix inet daemons.

   Although the Windows remote shell service and the Windows telnet service might be running on the host, you should disable the Windows daemons and use the Interix daemons instead. To disable the Windows services, go to "Control Panel"/"Services" and stop the services, set the start type to "disabled". To enable the Interix daemons, edit the /etc/inetd.conf file. It already contains lines for the daemons that are commented out. Remove the comment character (#) and save the file. Then run "/etc/init.d/inet start" to start the daemons. These daemons are necessary to make the N1GE commands qrsh and qlogin working.

   If the user wants to do a passwordless rlogin to the host and wants to have access to network resources then, the user must register the password with the Interix command "regpwd". This is because the network component of Windows never trusts a passwordless login, with the registered passwords the rlogind can emulate a login with password."

7. Configure the users' home directories.

   If the users' home directories are located on an NFS server, this must be configured in Windows. In the "profile" tab of the users properties dialog, select "Connect", a free drive letter and enter the path to the users home directory in the UNC notation \\server\share\directory, e.g. "\\myserver\home\Peter".
