Integrating Fedora Linux into a Windows network is reasonable and easy as long as you use the SAMBA utilities. I share the main steps necessary to implement such a SAMBA server within most Windows environments.

Once integrated a Linux server looks and acts exactly like any other server on a Windows intranet. You will have the ability to drag and drop files, view server contents and directories using Windows File Manager, and even edit files on a Linux server from any Windows desktop.

This article is a guide to setting up a full fledged FEDORA LINUX/SAMBA server. If you're a system administrator and are planning to integrate the Linux server into your AD server environment, I'm sorry I do not go into details how to configure smb.conf for ADS usernames, although it can be done. I will walk you through the main steps for installing a SAMBA Server. This, in my opinion, is the first part to any future more advanced integration.

First, you must allow the Linux server full rights and access to the Windows workgroup and local domain. That means that either in your Active Server environment you need to reserve an IP address for the Linux server, or you simply need to ensure a hard coded IP address is given to the Linux server. The server must have a reserved IP address whether you deliver it via DHCP or statically assign it in the DNS. This also means that you need to ALLOW SMB DAEMON to operate. You can ensure your system security does this by editing your Firewall setup or using system-config-securitylevel .
Second, you must ensure that SAMBA (SAMBA tools and the SMB protocol) is installed and running on the Linux server. Most versions of Fedora come with the necessary packages. You should also be sure to update your SAMBA security levels properly if you are having trouble accessing a shared directory. This is found under Samba Server Configuration tool, main menu Properties, option Server Settings, and then the tab: Security.

Now you are ready to configure your Fedora Linux/SAMBA machine... aka. SAMBA Server.

STEP 1: Enable Network Connectivity to the SAMBA Server

Using the Fedora Network Configuration tool you will need to ensure that the ethernet card is enabled and properly functioning. Get quick access to the tool through this command: system-config-network. Once in the Network Configuration tool, you should ensure that your ethernet device is enabled. If it is not, select the eth device and then click on the Edit button. This will allow you to input the vital network adapter settings including: statically set IP address, subnet mask, and gateway. You should also select the top checkbox labeled Activate device when computer starts.

Close and save any changes you've made. The main goal is to ensure you have an ACTIVE and functioning network card on the SAMBA server.

Restart the network services or simply reboot your SAMBA server. Now try a ping to the server from another PC on the same subnet. At a command prompt, for example, type: ping

The ping should come back good validating your network connection. If you need more Linux system administration help read my Admin Commands List.

STEP 2: Update Firewall Settings

In most cases the default Firewall setting on the SAMBA server locks out any inbound network requests. I've had a great many people come running to me about this issue. If you're setting up a basic SAMBA server within your business intranet, allow your ethernet connection to be a trusted device so others can get to your SAMBA server and not be bounced by the server's Firewall.

NOTICE: if you plan to use the SAMBA server outside of your business firewall/intranet you should NOT follow the next step. Instead you allow your local server to receive packets by making changes to your IPTABLES, such as:
iptables -A INPUT -s -j ACCEPT

The following step is for those using an intranet business server configuration.

Okay, now to allow your intranet based SAMBA server to properly accept incoming requests, from your Main menu choose System Settings, then Security Level. You can access this also by typing the command:

Please select the box next to the ethernet card you are using for intranet connectivity so that it becomes a TRUSTED DEVICE. Otherwise you have a super secure server that bounces inbound requests. Notice, this selection effects all the items in the Services listing above it, so please be careful in what context you allow a trusted device!
Press OK when finished.

STEP 3: Enable SMB Services

Ironically, the SMB daemon and other core services are usually NOT started by default. You will need to change this so that your SMB daemon is now started.

Using the GUI from the main menu, go to System Settings, then Server Settings, then choose Services. You can also get to this using the command: system-config-services

While you're looking over this long list of services, please DISABLE things you know for sure you do not need to run on this SAMBA server. For instance apmd, isdn, etc. But also ensure that key services such as SMB are selected and RUNNING. Select SMB and press the Start button. If it is supposedly already running you can press the Restart button to be sure it is indeed running correctly now.

Now press the Save button to make sure the configuration changes have been saved for future restarts.
Sometimes using the GUI just does not properly restart the SMB daemon. In such odd cases, I want to suggest you force a manual restart from the command line with this command: /etc/rc.d/init.d/smb restart

If you keep having startup failures, where for every reboot you need to perform Step 3, you may need to manually configure your start up processes so that SMB will always be in the init.d bootup.

STEP 4: Create Server Users & Directories
You will need to ensure that people also have a login to the SAMBA server to do their work. Logins should be provided on an as needed basis. Obviously, in most cases the users accessing the SAMBA server will be a subset of the total users on the Windows business network.

Create user logins with the Gnome User Manager tool in Fedora. You can find this from the main menu by choosing System Settings, then Users & Groups. The command for this is: system-config-users
Notice this is the first step in creating SAMBA users, which comes later.

Add as many users as you need and then move on to the next part, which is creating directories (aka. folders) for use.
This is such an obvious step most people usually forget to think about it before hand. However, it is very helpful to think ahead what directories you will allow access to on the SAMBA Server for business use. In my case the people needing SAMBA server access will be updating webpages. Therefore, I do not need to add any other folders for file sharing or group interaction. Be sure you add any folders in a reasonable and ordered fashion.

A big TIP for those who are not aware, the permissions settings for your folders are very important.

STEP 5: Configure the SAMBA Server
It's time to configure your SAMBA server to allow others on the intranet to login and use the server from Windows or Linux PCs.

From the main Fedora menu, choose System Settings, then Server Settings, then Samba. You can also get to this tool by typing the command: system-config-samba
You are about to make changes to the SAMBA Configuration file called smb.conf. This file is found under /etc/samba. I also want you to be aware that you can edit configuration files with the web interface tool called Samba Web Administration Tool(SWAT) and several others. Now lets move ahead using the Configuration tool using the preloaded Fedora tools. NOTICE that many people begin by tinkering with their .conf file... this is NOT a good idea. First ensure that the basic samba connectivity works and THEN you can tinker with the smb.conf! (see troubleshooting below)

A. Begin by Making Changes to the Server Settings

Under the Preference menu item choose Server Settings...

Be sure to include the Windows workgroup name. In the example above the workgroup has been changed to net. Your situation may be different. In many cases naming the workgroup simply workgroup is fine, so long as your Windows PCs connect to this same name.
Under this same window, click on the Security tab. It comes by default with the appropriate settings for a basic SAMBA Server. The Authentication mode should be User. You would need to change this only if you plan to allow logins based on the Microsoft ADS.

Press OK to finish making basic changes to the server.

B. Select SAMBA Users

Under the Preference menu item choose Samba Users

In this window you must Add at least one user who will have access to the SAMBA Server. Notice that only user accounts you created in step 4 should be added to this listing.

Press the Add User button, then from the pull down select a user. Fill out the additional information needed for this SAMBA user. Press OK when finished.

C. Adding A Shared Folder

Under the SAMBA Server Configuration window, you must create at least one SAMBA share directory.

Press the Add button and then the Browse button. Now choose a folder you wish to make available to SAMBA users. Be careful, some folders have permissions settings that do not allow sharing. Now be sure to select the Read/Write option to allow people full access. Don't press OK yet!

You should see your shared folder appear under the listing as shown in the example above.

D. Adding Users

In the same window, select the second tab labeled Access. From here choose the first option labeled Only allow access to specific users and select the users you wish to give access to this specific SAMBA shared folder. Press OK when finished.
You can repeat steps C and D for each new shared folder.

Once completed, please choose File from the menu then choose Quit.

Hopefully this saved all of your settings properly. If you encounter issues with the graphic SAMBA configuration tool, such as it failing to accept your changes, then please read the Troubleshooting Tip 4 located below.

STEP 6: Restart the SAMBA Services

Now you need to restart all SAMBA services. You can use the process found in Step 3, except press the Restart button or use the word restart instead of the word start.

I mentioned earlier that sometimes your changes do not get properly picked up. I've installed so many different Fedora SAMBA configurations that I can't recall every reason. This may be a very good time to simply reboot the LINUX/SAMBA Server. Rebooting will ensure everything gets properly started up and all of the configuration changes are included. More importantly, this is likely the last time you will ever restart your SAMBA server again. Some of my FEDORA servers haven't been restarted in years.

STEP 7: Access the SAMBA Server from Windows
You're now ready to fully utilize your new intranet SAMBA Server for work. On any Windows PC you can access the server by simply going to the main Start menu, choosing Run and typing in the hostname of your SAMBA server. For example:


Please notice that in the Windows environment you use different slashes and you need to ensure this syntax.

If this does not work, perhaps if the server is not yet included in your DNS, try accessing the SAMBA Server through its IP address: \\

Obviously you need to use an actual hostname or IP address and not my example.

If all works well you should instantly see a SERVER LOGIN window. Now login using a SAMBA created username.

You should then instantly see the shared folder as well as the individual user's personal folder that exist on the SAMBA Server.

Congratulations, you're done. cool biggrin cool

NOTICE: I've had a number of people who encountered issues because they seriously screwed with their smb.conf file or forgot to update their Samba Server Security settings found under the Server Setup, Security tab. Please, please, before you start tinkering with your smb.conf file try to use the BASIC samba settings to ensure you ACTUALLY CAN CONNECT properly. Then when you make changes you can far better identify what goes wrong. Following the steps above should work in almost every situation IF you first start with the basic configuration.

1. SAMBA Server is not accessible

First and foremost try a reboot to the server itself! It is vital you do this before someone talks you into changing configs, playing with your network card settings etc. Just reboot and try again to see if it clears up the issue.

2. Network Unreachable or Host Unreachable From Linux PCs

Trying to connect from another Linux PC and nothing happens or "network unreachable" may be as ridiculous as an incorrect SAMBA connection. Make absolutely certain that the connection is typed in exactly as follows (obviously changing the workgroup name to your windows workgroup): smb://WORKGROUP
On some KDE desktops, attempts failed because the syntax incorrectly tries: smb:/workgroup Those // are quite important!

3. Failure to Connect from Windows PCs

Not connecting to the server from Windows PCs may be a result of bad network configuration. Are you absolutely certain you entered the correct network details? Please double check to make sure that you have a proper hostname for the Samba server, that you have a working IP address, and the correct Subnet and Gateway included. In most cases these last two should simply match what your windows PCs have designated.

4. Changes to the configuration are not being picked up

The Gnome SAMBA Configuration GUI often encounters errors when trying to update new SAMBA settings. I've seen the GUI tool write a whole lot of garbage into the SAMBA configuration file (smb.conf). For this reason, as I mentioned earlier, you may need to start with a fresh clean smb.conf file and try again, or you may need to manually adjust settings without the GUI.

5. Can't Share Folder in Home Directory

First, it's always a good idea NOT to make a Samba share out of directories inside your Home folder for security reasons. Making unique share folders is often the best bet. However, there are times when you need to share a folder and the way to do so is to update your Samba Share's security settings. Under the Samba Configuration, highlight your shared directory and press Properties. Here you can see the "Basic Permissions" list and usually the default is "Read Only." Select the "Read/Write" option and be sure to save your changes by quitting and then restarting the smb daemon. If this doesn't resolve the issue of directory shares, you may have a more fundamental security issue. You need to ensure that the over all Samba security settings under "Preferences", then "System Settings" and then the Security tab are correct.
