When PC-NFS software users need only generally accessible exported file systems and do not need networked printer services, the Irix administrative tasks can be limited to issuing network addresses and host names. User authentication services and shared network printing support require the addition of the PC-NFS Daemon on an Irix server. The PC-NFS daemon (pcnfsd) program is provided because the MS-DOS operating system (on the PC) does not offer the diversity of a multiuser Irix environment. While the PC-NFS product provides its essential functions without special arrangements on the NFS server side, pcnfsd is necessary to broaden the range of options available to MS-DOS users. Specifically, pcnfsd provides the following services: AUTHENTICATION This is a way for users to identify themselves to the Irix Operating System and to be granted appropriate privileges for file access and program execution on the network. ACCESS TO PRINTER SPOOLING SERVICES This enables PC users to print on printers attached to servers on the network (including printers driven by the Impressario software), and to monito and delete print jobs in network print queues. The pcnfsd version supplied on this CDROM is version 2. This is compatible with PC-NFS versions up to and including 5.0. This version provides expanded user authentication and enhanced printing services. While the enhanced services are of general use, the printing services have been tailored to be compatible with Microsoft(r) Windows(tm) 3.x. To find out if pcnfsd is already running and what version it is, use this command on your workstation: WhatVersion or this command on your PC: rpcinfo -u SERVER 150001 2 Where SERVER is replaced with the name of the machine suspected of running the pcnfsd. If pcnsfd is running you will get one of two messages in reply: PC-NFS is not running or version 1.0 is running. ------------------------------------------------ > rpcinfo -u IRIS 150001 2 rpcinfo: Program not registered program 150001 version 2 is not available PC-NFS is running and ready to go. ---------------------------------- > rpcinfo -u IRIS 150001 2 program 150001 version 2 ready and waiting INSTALLATION: In order to install pcnfsd, execute as root: > su # ./addpcnfs.sh At this point in time pcnfsd will be installed, and the system will restart pcnfsd every time the system is rebooted. You will need to re-boot your machine to start the pcnfsd initially. You may then control pcnfsd via the IRIX chkconfig configuration tool as follows: > su # chkconfig pcnfsd [on/off] followed by a reboot. HOW TO SETUP THE PC: Once you have pcnfsd running on your workstation, you may enter the following command on the PC-NFS client PC: NET PCNFSD * NET LOGIN username * These commands may be added to your PC-NFS startup file, usually named: NETWORK.BAT FILE SHARING WITH PC-NFS: In order to share files, you need to have the (optional) NFS support package installed on your Iris workstation. To find out if you have it installed, enter the following command: > versions nfs I = Installed, R = Removed Name Date Description I nfs 03/03/94 Network File System, 5.2 I nfs.books 03/03/94 IRIS InSight Books, Release 2.2 I nfs.books.NFS_AG 03/03/94 NFS Administration Guide I nfs.books.NIS_AG 03/03/94 NIS Administration Guide I nfs.man 03/03/94 NFS Documentation I nfs.man.nfs 03/03/94 NFS Support Manual Pages I nfs.man.relnotes 03/03/94 NFS Release Notes I nfs.sw 03/03/94 NFS Software I nfs.sw.nfs 03/03/94 NFS Support I nfs.sw.nis 03/03/94 NIS (formerly Yellow Pages) Support Then, you need to make sure NFS support is turned on. Check this with the following command: > chkconfig Flag State ==== ===== nfs on <= Indicates NFS is enabled. Then you need to export directories for PC-NFS to mount. You can do this as follows: > su # cd /etc # jot exports (Now add a line to this file like:) /usr/tmp -rw (Save the file and exit jot) # exportfs -a # exit In this example, the /usr/tmp directory is exported to everybody with full read/write privileges. Now, on the PC, add a line to your DRIVES.BAT file like this: NET USE T: IRIS:/usr/tmp where "IRIS" is replaced by the name of the machine who's directory you wish to mount. PRINT REDIRECTION WITH PC-NFS: One of PC-NFS's major features is to allow PC's access to the print spooling services available on your workstation. This feature is referred to as "print redirection". Several additional steps need to be done in order to support print redirection with PC-NFS. First, you need to create a print spooling directory for PC-NFS. Do that as follows: > su # umask 0 # cd /var/spool # mkdir pcnfs # exit NOTE: This directory is automatically created for you when you install the PC-NFS daemon. Then, you need to export this directory with *no* access restrictions so that PC-NFS may access the directory for print spooling. Do so as follows: > su # cd /etc # jot exports (Now add a line to this file like:) /var/spool/pcnfs (Save the file and exit jot) # exportfs -a # exit NOTE: When you export the /var/spool/pcnfs directory, be *sure* there are absolutely *no* restrictions, including, for example, '-rw' or print spooling will not work. Then, in the System Manager, open the Printers tool, add a printer definition if one does not exist yet, either local or remote, and then select one or more printers (by name) to use for PC-NFS printing, for example, assume you have a printer named "printer". Now, on the PC, add a line to your DRIVES.BAT file like this: NET USE LPT1: IRIS:printer After running the DRIVES.BAT file, you will be able to use the network printer for output from your PC-NFS system.
