In simple terms, the Intranet is the descriptive term being used for the implementation of Internet technologies within a corporate organisation, rather than for external connection to the global Internet. This implementation is performed in such a way as to transparently deliver the immense informational resources of an organisation to each individuals desktop with minimal cost, time and effort. This document attempts to explain in simple terms how to setup an Intranet using tools which are readily available and are generally costing little or are free.
This document assumes that you already know how to install TCP/IP on your Linux server and connect it physically to your LAN using an Ethernet network card. This also assumes you have some basic knowledge of Netware, WinNT and Mac systems. The configuration of the Netware server has been shown using version 3.1x as the basis. You can also use INETCFG to achieve the same result. On the client side the discussion is with respect to Windows 3.1x, Windows for Workgroups and Win95, WinNT and the Apple PowerMac.
I am using the private network addresses (RFC-1918) of 172.16.0.0 and 172.17.0.0 only as examples. You may choose suitable addresses depending on your configuration.

When you download the server you have two options: To get the source and compile it yourself, or get the precompiled binaries. The precompiled binaries for Linux (ELF) version are available at NCSA but not the older versions.
The server at NCSA will guide you through the steps for configuration options and prepare the various files for you. But before you attempt to download HTTPd be prepared with answers to the following questions
First, you must choose whether to download the source or a pre-compiled version of the software. If your particular system doesn't appear in the menu, then you will have to get the default source, and compile it yourself.
To check the version of your Linux go to the command prompt on your Linux machine and type
linux:~$ uname -a
linux:~$ uname -a
Linux linux 2.0.29 #4 Tue Sep 13 04:05:51 CDT 1994 i586
linux:~$
The version of Linux is 2.0.29.
The remaining parameters can be specified before downloading or configured later by modifying the file srm.conf in the /usr/local/etc/httpd/conf directory. The names of the actual directives that appear in the file httpd.conf are shown in brackets. The only exception is the directive DocumentRoot which appears in the file srm.conf
This specifies how your machine will run your HTTPd server. The preferred method is "standalone". This makes the HTTP daemon to be running constantly. If you choose to load HTTPd under "inetd", the server binary will be reloaded into memory for every request, which may slow your server down.
This specifies which port of your machine that the HTTPd daemon will bind to and listen for HTTP requests. If you can login as "root", use the default setting of 80. Otherwise choose a setting between 1025 and 65535.
This is the user id the server will change to when answering requests and acting on files.This question needs to be answered only if you are running the server as "standalone". If you are someone without root permissions, just use your own login name. If you are system administrator, you might want to create a special user so you can control file permissions.
This is the group id the server will change to when answering requests and acting on files. This is similar to Server User identity and is applicable only if you are running the server as standalone.
If you do not have root permissions, just use the name of your primary group. You can find out your group by typing groups at the Linux command prompt.
This is the email address that the user should send an email message to when reporting a problem with the server. You can put your personal e-mail address.
This is where the server resides on your system. If you have root permissions leave it in its recommended location /usr/local/etc/httpd. If you cannot login as root, choose a subdirectory in your home path. You can find out the path of your home directory with the pwd command.
This is where the HTML files to be served are located. The default location is /usr/local/etc/httpd/htdocs.
You could however set it to be the home directory of the special user you chose in Server user identity, or a subdirectory
in your home directory if you can't login as root.
When in doubt, use the default settings. Now that you have answers to the above questions you can Download NCSA HTTPd at
http://hoohoo.ncsa.uiuc.edu/docs/setup/OneStep.html. You should read the HTTPd Documentation at
http://hoohoo.ncsa.uiuc.edu/docs/ before you attempt installation. If you are planning to compile the code then you need to modify the makefiles in each of the th
ree directories support, src, cgi-src. If your version of Linux is already supported then you just have to type make linux at the top level directory (i.e. /usr/local/etc/httpd)
Compiling is simple, just type make linux at the prompt in the server root directory.
Note: Users of pre-ELF Linux have to uncomment #define NO_PASS in file portability.h and set DBM_LIBS= -ldbm in the Makefile before compiling HTTPd.
After you have installed HTTPd, login as root and start it by typing httpd & . (assuming you have installed as standalone) You should now be able to see it in the list generated by ps. The simplest way to test HTTPd is by Telnet. At the Linux command prompt type
linux:~$ telnet 172.16.0.1 80
Trying 172.16.0.1...

Now we are ready to connect to this server using another PC and a WWW Browser.
Please refer to the diagram shown in the chapter Introduction for the addressing scheme used. Workstation 1 (W/S1) is on network 172.16.0.0 and can access the Linux server directly whereas Workstation 2 (W/S2) is on network 172.17.0.0 and needs to use the gateway (router) 172.17.0.254 to access the Linux box. This gateway information needs to be provided while configuring the clients only on W/S2. Netware refers to the gateway as 'ip_router'.
I am using W/S2 to illustrate the client setup. To setup W/S1 just change the address 172.17.0.5 to 172.16.0.5 and ignore all references to the gateway/router.
If you do not have a router you can skip the next section and proceed to
You may skip this section if you do not have a router.
You have to configure the Linux server to recognise the router thus allowing Workstation 2 to connect to the Web server. In order to setup the Linux server you should login as root. At the server prompt type
route add gw default 172.16.0.254
/etc/rc.d/rc.inet1 and change the line containing the gateway definition to GATEWAY = "172.16.0.254". Make sure the line for adding the gateway is not commented out.
ALT: You can add routes to the networks on the other side of the router. This would be done as
route add -net 172.17.0.0 gw 172.16.0.254
/etc/rc.d/rc.local file.
In order to setup the Netware server you should have Supervisor permissions or atleast Console operator permissions. If these cannot be got, try asking your Network Administrator to help you with the setup. At the Server enable the Ethernet_II frame type on the LAN by typing these commands or include them in the AUTOEXEC.ncf file.
load NE2000 frame=Ethernet_II name=IPNET
load TCPIP
bind IP to IPNET addr=172.16.0.2 mask=FF.FF.FF.0
You might have to specify the slot or board number while loading the NE2000 driver depending on your machine configuration. (eg: load NE2000 slot=3 frame=.....)
On the PC you have the choice of Win3.1,WFWG or Win95. The installation procedure differs between Win95 and the older windows if you are using the 32bit client from Microsoft or Novell. If you are going to use the 16bit client, the procedure is the same and you can refer to the Windows 3.x installation instructions. For installing the 32bit client for Win95 skip to Windows 95 installation.
If you are using Win3.1 or WFWG you can install the Netware Client (VLMs) and some additional files which are provided with the TCP/IP diskette, namely
TCPIP.exe, VTCPIP.386, WINSOCK.dll and WLIBSOCK.dll
Note that the WINSOCK.dll file is different from the ones provided with Win95 and Trumpet. Install the Netware Client with the support for windows. Copy VTCPIP.386, WINSOCK.dll and WLIBSOCK.dll to the SYSTEM directory and TCPIP.exe to the NWCLIENT directory. Now modify the STARTNET.bat in the NWCLIENT directory to
lsl
ne2000 ---> your network card driver
c:\windows\odihlp.exe ---->if you are using WFWG
ipxodi
tcpip ---> add this line
nwip ---> if you use Netware/IP
vlm
Create a subdirectory (say) \NET\TCP and copy the files HOSTS, NETWORKS, PROTOCOLS and SERVICES from /etc on your Linux server or the directory SYS:ETC on your Netware server. Edit the copied HOSTS file to add the line for your new Linux server. This will enable you to refer to the Linux server as http://linux.mydomain/ instead of http://172.16.0.1/in your WWW browser
127.0.0.1 localhost
172.16.0.1 linux.mydomain

Note: To enable you to refer to the Linux server ashttp://linux.mydomain/ instead of http://172.16.0.1/ in the WWW browser and all your intranet commands you need to edit the hosts file. You can add more entries for each of your other hosts (Netware, Unix, WinNT) as well. The Windows family keeps its HOSTS file in \WINDOWS or in \WINDOWS\SYSTEM depending on the version. Edit this file and add a line for your Linux server as:
127.0.0.1 localhost
172.16.0.1 linux.mydomain
172.16.0.2 netware.mydomain
172.16.0.3 winNT.mydomain
172.16.0.5 ws_1

If you are using the Macintosh for accessing your network, then this section details how to install MacTCP for the PowerMacs.
Note: To enable you to refer to the Linux
server as http://linux.mydomain/ instead of
http://172.16.0.1/ in the WWW browser and all your intranet
commands you need to edit the hosts file. The format of the
hosts file is different from the one used in Unix. The Mac hosts file is
based on RFC-1035. You can add more entries for each of your other hosts
(Netware, Unix, WinNT) as well. The MacOS keeps its HOSTS file in the
Preferences folder under the System folder. Edit this file and add a line
for your Linux server as:
linux.mydomain A 172.16.0.1
netware.mydomain A 172.16.0.2
winNT.mydomain A 172.16.0.3

Enter your gateway (router) address in the box
Router address as 172.17.0.254
An Intranet cannot be complete without sharing the resources on the different platforms. You will need support for other filesystems, so that you can access the data available on them. This document provides instructions to connect Linux to the following popular filesystems.
These filesystems can be compiled into the Linux kernel or added as modules, depending on the version of Linux. If you are not familiar with compiling the kernel you can refer to the Kernel HOWTO http://sunsite.unc.edu/mdw/HOWTO/Kernel-HOWTO.html and the Module HOWTO http://sunsite.unc.edu/mdw/HOWTO/Module-HOWTO.html for compiling the kernel with modules.
To share the files on the Netware server you will need support for NCP (ncpfs). NCPFS works with kernel version 1.2.x and 1.3.71 upwards. It does not work with any earlier 1.3.x kernel. It cannot access the NDS database in Netware 4.x, but can make use of the bindery. If you are using Netware 4.x you can enable bindery support for specific containers using the command Set Bindery Context at the console as:
set Bindery Context = CORP.MYDOM;WEBUSER.MYDOM
You will need to download the NCP filesystem utilities using the URL ftp://sunsite.unc.edu/pub/Linux/system/filesystems/ncpfs/ncpfs.tgz (currently ncpfs-2.0.10) from Sunsite.
To install the ncpfs utilities, type
zcat ncpfs.tgz | tar xvf -
ncpfs-2.0.10 Change your directory to this ncpfs directory before proceeding with the installation. Read the README and edit the Makefile if necessary.
The installation of ncpfs depends on the kernel version you are using. For kernel 1.2, you should simply type 'make'. Subsequently typing 'make install' will install the executables and man pages.
If you use Kernel 1.3.71 or later, you might have to recompile your kernel. With these kernels, the kernel part of ncpfs is already included in the main source tree. To check if the kernel needs to be recompiled type
cat /proc/filesystems
If ncpfs is not there, you can either recompile the kernel or add ncpfs as a module. For recompiling the kernel you should type 'make config' and when it asks you for
The IPX protocol (CONFIG_IPX) [N/y/?]
simply answer 'y'. Probably you do not need the full internal net that
you are asked for next. Once the kernel is successfully installed, reboot, check /proc/filesystems and if everything is OK proceed with the installation of the ncpfs utilities. Change directory to the location holding your downloaded ncpfs files, and type 'make'. After the compilation is finished type 'make install' to install the various utilities and man pages.
To check the installation type
ipx_configure --auto_interface=on --auto_primary=on
....wait for 10 seconds and type
slist
Suppose we need to access HTML files from directory \home\htmldocs on volume VOL1: on the server MYDOM_NW, I recommend that you create a new user (say) 'EXPORT' with password 'EXP123' on this server to whom you grant appropriate access rights to this directory using SYSCON or NWADMIN.
On the Linux machine create a new directory /mnt/MYDOM_NW. Now type the command
ncpmount -S MYDOM_NW -U EXPORT -P EXP123 /mnt/MYDOM_NW
ls /mnt/MYDOM_NW/vol1/home/htmldocs
MYDOM_NW/VOL1:\HOME\HTMLDOCS (using Netware file notation). If you have any problems please read the IPX HOWTO at
http://sunsite.unc.edu/mdw/HOWTO/IPX-HOWTO.html for more insights into the IPX system.
To share the files on the Windows server you will need support for SMB (smbfs).
You will need to download the SMB filesystem utilities from ftp://sunsite.unc.edu/pub/Linux/system/filesystems/smbfs/smbfs.tgz (currently smbfs-2.0.1) from Sunsite.
To install the smbfs utilities, type
zcat smbfs.tgz | tar xvf -
smbfs-2.0.1 Change your directory to this smbfs directory before proceeding with the installation. Read the README and edit the Makefile if necessary.
The installation of smbfs depends on the kernel version you are using. For kernel 1.2, you should simply type 'make'. Subsequently typing 'make install' will install the executables and man pages.
If you use Kernel 2.0 or later, you might have to recompile your kernel. With these kernels, the kernel part of smbfs is already included in the main source tree. To check if the kernel needs to be recompiled type
cat /proc/filesystems
If smbfs is not there, you can either recompile the kernel or add smbfs as a module. For recompiling the kernel you should type 'make config' and when it asks you for
adding SMB filesystem support
simply answer yes. Once the kernel is successfully installed, reboot, check /proc/filesystems and if everything is OK proceed with the installation of the smbfs utilities. Change directory to the location holding your downloaded smbfs files, and type 'make'. After the compilation is finished type 'make install' to install the various utilities and man pages.
In our example let us assume that the WinNT server is called 'MYDOM_NT' and is sharing its directory C:\PUB\HTMLDOCS with a share name of 'HTMLDOCS' without a password. On the Linux machine create a new directory /mnt/MYDOM_NT. Now type the command
smbmount //MYDOM_NT/HTMLDOCS /mnt/MYDOM_NT -n
to mount the SMB (windows share) file system. If this does not work try
smbmount //MYDOM_NT/COMMON /mnt/MYDOM_NT -n -I 172.16.0.3
Typing the command
ls /mnt/MYDOM_NT
bsol;bsol;MYDOM_NT\PUB\HTMLDOCS (using Windows file notation).
First you will need a kernel with the NFS file system either compiled in or available as a module.
Suppose you have a Unix host running NFS with the name MYDOM_UNIX and an IP address of 172.16.0.4. You can check the directories that are being exported (shared) by this host by typing the command
showmount -e 172.16.0.4
mount -o rsize=1024,wsize=1024 172.16.0.4:/pub/htmldocs /mnt/MYDOM_UNIX
If you have any problems please read the NFS HOWTO at http://sunsite.unc.edu/mdw/HOWTO/NFS-HOWTO.html for more insights into the NFS system.
Now that we have setup the HTTP server, the clients and interconnected the Linux server with the other servers, we need to make some small adjustments on the Linux server to be able to access these mounted filesystems from the Web Browser.
To access the mounted directories in your HTML pages you have two methods:
/usr/local/etc/httpd/htdocs) to refer to the mounted directory as
ln -s /mnt/MYDOM_NW/vol1/home/htmldocs netware
or
ln -s /mnt/MYDOM_NT winNT
or
ln -s /mnt/MYDOM_UNIX unix
srm.conf in your /usr/local/etc/httpd/conf directory and add a new alias.
# Alias fakename realname
Alias /icons/ /usr/local/etc/httpd/icons/
# alias for netware server
Alias /netware/ /mnt/MYDOM_NW/vol1/home/htmldocs/
Alias /winNT/ /mnt/MYDOM_NT/
Alias /unix/ /mnt/MYDOM_UNIX
http://linux.mydomain/netware/index.htm for the netware files and similar notations for the others.
You can finally connect your Intranet to the Internet to access E-Mail and all the wonderful information out there. I propose to write a brief note on how to do this in a future revision. Detailed explanations are available in the ISP Hookup HOWTO from http://sunsite.unc.edu/mdw/HOWTO/ISP-Hookup-HOWTO.html and Diald mini HOWTO at http://sunsite.unc.edu/mdw/HOWTO/mini/Diald for setting up these connections.
The HTTP server can be used in the office to provide transparent access to information residing on different servers, at several locations and directories. The data can be simple documents in Word, Lotus spreadsheets, or complex databases.
The application of this technology is being typically used as follows:-
These documents can include newsletters, annual reports, maps, company facilities, price lists, product information literature, and any document which is of value within the corporate entity.
Rapid access to corporate phone books and the like. This data can be mirrored at a Web site or, via CGI scripts, the Web server can serve as a gateway to back-end pre-existing or new applications. This means that, using the same standard access mechanisms, information can be made more widely available and in a simpler manner. This means that it can be used to create an interface with RDBMS like ORACLE and SYBASE for generating real-time information. Here is a list of links to such sites on the Web.
- Web Access - http://cscsun1.larc.nasa.gov/~beowulf/db/web_access.html - CGI gateways - HTTP://www.w3.org/hypertext/WWW/RDBGate/Overview.html
As cultures change within organistions to the point where even each department moves towards their own individual mission statements, the Intranet technology provides the ideal medium to communicate current information to the Department or Individual. Powerful search engines provide the means for people to find the group or individual who has the answers to the continuous questions which arise in the normal day-to-day course of doing business.
With HTML forms support, sites can provide sign-up sheets, surveys and simple scheduling.
Administrators can use the Intranet to deliver software and up-dates on-demand to users across the corporate network . This can be done with 'Java' which allows the creation and transparent distribution of objects on-demand rather than just data or applications. This is indeed possible more easily with the newer versions of Linux which has builtin support for Java.
With the move to the use of Intranet mail products with standard and simple methods for attachment of documents, sound, vision and other multimedia between individuals, mail is being pushed further forward as a simple, de facto communications method. Mail is essentially individual to individual, or individual to small group, communication. Several utilities are available on the Linux platform to setup an E-mail system like sendmail, pop3d, imapd.
The Intranet technology is evolving so rapidly that the tools available, in particular HTML, can be used to dramatically change the way we interface with systems. With HTML you can build an Interface which is only limited by the creators imagination. The beauty about using Intranet technologies for this is that it is so simple. Clicking a hyperlink from HTML can take you to another page, it could ring an alarm, run a yearend procedure or anything else that a computer program can do.
Here is a list of other interesting things to do with your Linux Intranet server. All the software mentioned below is freeware or shareware.
Thanks to the people at NCSA for providing such excellent documentation, David Anderson and all others for trying out this HOWTO and sending in their comments. The details on Netware/IP are courtesy Romel Flores (rom@mnl.sequel.net).
