Note that remote administrative access is disabled by default and must be specifically enabled through the Remote Access panel of the server manager. If you are not familiar with working from the Linux prompt, you may be interested in trying a file management tool called Midnight Commander. It allows you to perform many file operations through a menu-driven interface.
Simply type mc at the command prompt. Press the function key "F1" for help and "F10" to quit. The next chapter, On-going Administration Using the server manager , explains this simple process. This chapter helps you configure software and hardware supplied by other companies and for that reason is not as specific as the rest of this guide.
Given the wide range of computers, operating systems and software applications, we cannot accurately explain the process of configuring each of them. If your computers and applications came with manuals, they might be useful supplements to this chapter.
Technical problems encountered in networking your desktop computers and applications are best resolved with the vendors who support them for you. This chapter demonstrates only one of the many possible ways to configure your client computers and is provided here as an example. The dialog box where you configure your desktop differs from operating system to operating system and version to version. To get there, go to the "Control Panel" and select "Network".
We strongly recommend that you configure all clients machines using DHCP rather than manually using static IP addresses. Should you ever need to change network settings or troubleshoot your network later, you will find it much easier to work in an environment where addresses are automatically assigned.
In some rare cases, you may want to use a static IP address for a particular client machine. The typical approach is to manually enter this IP address into the network properties of the specific machine. The negative side of this approach is that you cannot easily change or alter network settings without having to go in and modify the information on the client machine. However, it is possible to provide this static IP address directly through DHCP rather than manually configuring the client computer.
To do so, you will first need to determine the Ethernet address of the client computer usually through the network properties. Next you will go to the Hostnames and addresses web panel of the server manager and enter the information there.
It is imperative that no other DHCP server is on your network. Leave DHCP enabled, and reboot each computer. As noted above, we strongly recommend that you perform all your client configuration using DHCP. It is even possible to assign a static IP address through the Hostnames and addresses. It is critical that every computer on your network has a unique IP address and that you don't assign two computers the same address. You also allocated a block of IP addresses for manual assignment.
If you accepted the defaults pre-configured into the server console, IP addresses To avoid duplication, use only those IP addresses when manually assigning IP addresses to your computers. Once the settings take effect, your computer will be connected to the server and to the Internet. If you are using a Microsoft operating system, you must ensure that your workgroup is the same as the workgroup name of your server.
The default workgroup name is your domain name. In a subsequent chapter, we'll explain how this can be changed using the web-based server manager. If you are using the default name, go to the Control Panel, select "Network" and then select "Identification".
In the field for "Workgroup", type your domain name. Once you've set up your server, there's typically a delay of one or more days before your ISP publishes your domain address records the domain name or names and the associated numerical IP address so that the information is accessible to other computers on the Internet.
Until it does, incoming mail won't be able to find you and computers elsewhere on the Internet won't be able to contact your server using your domain name for example, www. However, on your local network you should be able to connect to your server using the short names of 'www' for web access and 'mail' for e-mail clients. Your server supports both protocols. You will need to select the protocol that is right for your organization.
POP3 is the earlier, better-known e-mail protocol. POP3 was designed to permit on-demand retrieval to a single client machine. E-mail is stored on the mail server until you retrieve it, at which time it is transferred over the network to your desktop machine and stored in your e-mail box there.
IMAP e-mail, in contrast, is designed to permit interactive access to multiple mailboxes from multiple client machines. You manage your e-mail on the mail server over the network.
You read your e-mail over the network from your desktop, but the e-mail is not stored on your desktop machine - rather, it is permanently stored and managed on the server. Because all employee e-mail is stored on the server, backup of e-mail is easily accomplished. If you are not connected to a network, new and stored e-mail messages are not available to you.
Each user's e-mail application requires information about that user's account, where to send outgoing e-mail and pick up incoming e-mail. This information is usually entered in the "preferences" or "options" section. Most e-mail applications require you to enter the following information:. User's e-mail address: The user's e-mail address is the user account as created in the server manager plus the domain name.
Typically it will be in the form of username yourdomain. Normally you should just enter mail here. If you prefer, you should also be able to use the full domain name of mail.
E-mail account name or user name: this is the name before the in the e-mail address. For example, the username for " afripp tofu-dog. Delete read e-mail from server: We recommend you configure your e-mail application so e-mail that has been read is not left on the server. To do this, click off the checkbox marked "leave mail on server" or click on the checkbox marked "delete mail from server".
The images below show you the sequence in Netscape. First you choose Preferences from the Edit menu and click on Mail Servers as shown in:. Otherwise, you will select the default mail server listed and click on the the Edit Most browsers are configured using a dialog box called "preferences", "network preferences" or "options".
Some browsers need to be configured to access the Internet either directly or via a proxy server. When required, most desktop applications, your web browser included, should be configured as though they were directly accessing the Internet. Although the server uses a security feature known as IP masquerading, thereby creating an indirect connection to the Internet, this is a transparent operation to most of your desktop applications.
Hence, you should ensure that the "Direct connection to the Internet" check box is clicked "on" in your web browser. Under certain circumstances, using a proxy server can improve the perceived performance of your network. Normally, we recommend these be disabled in your browser. If you decided that you do want to use proxy servers [ 3 ] , you will need to enter the IP address or domain name of the proxy server i.
The port number you will need to enter to connect to the proxy server is Your SME Server will automatically create a company directory and update it as you maintain your e-mail accounts. The next chapter explains how to configure this service. For example, with Netscape, look under the "Communicator" menu and choose "Address Book".
Then look under the File menu and select "New Directory". You will see a dialog box similar to the one shown here. The LDAP server is the name of your web server, in the form www. The Server Root information can be found on the "Directory" screen in your server manager more information on this is available in the next chapter. The usual form, assuming your domain is yourdomain.
Once the address book has been created, Netscape can display a list of all e-mail accounts if you type an asterisk into the search field and press "Enter". The server manager is a simple control panel that allows you to administer your network. Using the server manager, you perform such tasks as adding or deleting e-mail addresses, setting the system date and time, and creating a starter web page. We recommend you bookmark this address so that you can return to it whenever you wish to access the server manager.
For security reasons, you are only able to access the server manager through a web browser on the local network. Remote access is only possible using remote access tools such as ssh and PPTP. When you arrive at the correct URL, you'll be asked to enter your user name which is always "admin" and the password you created during the installation process.
Enter that information and click "OK" to be taken to the server manager. It will look like the screen shown above. In the next four chapters, we'll explain each of the administrative functions in the order in which they appear in the frame running down the left side of the screen.
The links are grouped together under four headings: Security, Configuration, Collaboration and Miscellaneous. As even one further layer of security, you can also connect to the server manager using the secure HTTPS protocol. This establishes an encrypted channel of communication between your browser and the server, even on your local network. This screen lets you change your system password at any time.
To do so, type the new password in the first field. Verify the new password by entering it in the second field. Your password can be any combination of printable characters, including upper- and lower-case letters, numbers, and punctuation marks.
If you make a mistake, click the "Back" button on your browser and try again. Note that whenever you change your password, the system will prompt you for the revised password as soon as you access another feature. If you're an advanced user, the SME Server provides several different ways to access the underlying operating system, either from a computer on your internal network or from a computer outside your site on the Internet.
Additionally, you have the ability to access your computer network securely from a remote computer.
All of these operations are configured from the screen shown below in the server manager. If you need to connect directly to your server and login from a remote system belonging to you, we strongly encourage you to use ssh instead of telnet. See the section below. If you do not have any reason to allow remote access , we suggest you set this to No access. Many people do not realize that many programs such as telnet and ftp transmit your password in plain, unencrypted text across your network or the Internet.
The ssh protocol was originally invented by SSH Communications Security which sells commercial ssh servers, clients, and other related products. The server provides the ssh client programs as well as an ssh server daemon and supports both the SSH1 and SSH2 protocols. Once ssh is enabled, you should be able to connect to your server simply by launching the ssh client on your remote system and ensuring that it is pointed to the external domain name or IP address for your server.
In the default configuration, you should next be prompted for your user name. After you enter admin and your administrative password, you will be in the server console. From here you can change the server configuration, access the server manager through a text browser or perform other server console tasks.
Allow administrative command line access over ssh - This allows someone to connect to your server and login as "root" with the administrative password. The user would then have full access to the underlying operating system. This can be useful if someone is providing remote support for your system, but in most cases we recommend setting this to No. Allow ssh using standard passwords - If you choose Yes the default , users will be able to connect to the server using a standard user name and password.
This may be a concern from a security point of view, in that someone wishing to break into your system could connect to your ssh server and repeatedly enter user names and passwords in an attempt to find a valid combination. A more secure way to allow ssh access is called RSA Authentication and involves the copying of an ssh key from the client to the server. This method is supported by your server, but is beyond the scope of this user guide and will eventually be covered by additional documentation on the contribs.
By default, only two user names can be used to login remotely to the server: admin to access the server console and root to use the Linux shell. Regular users are. A number of different free software programs provide ssh clients for use in a Windows or Macintosh environment. Several are extensions of existing telnet programs that include ssh functionality. Note that the client is free for evaluation, academic and certain non-commercial uses. A VPN is a private network of computers that uses the public Internet to connect some nodes.
PPTP allows users to connect to their corporate networks across the Internet. If you have a remote Windows system for instance, a laptop or a home computer that has access to the Internet, you can also access the information stored on your server. If you wish to enable VPN access, you must decide how many individual PPTP clients you will allow to connect to your server simultaneously, and enter that number here.
The simplest method is to enter the total number of remote PPTP clients in your organization. Alternatively, if you have a slow connection to the Internet and do not want all of those PPTP clients to connect at the same time, you can enter a lower number here. For instance, if you have five users who from time to time use PPTP to connect remotely, entering 5 here would allow all of them to connect at any time.
Entering 2 would only allow two users to connect at any given time. If a third user tried to connect, he or she would receive an error message and would not be able to connect until one of the other users disconnected. If, on the other hand, you entered 0 , no PPTP connections would be allowed. Typically, this is done through the Network Control Panel you may need to have your original Windows installation CD available.
After it is installed a reboot of your Windows system may be needed , you can create new connections through the Dial-Up Networking panel by entering the external IP address of the server you wish to connect to.
Once you're finished, you should be able to initiate a PPTP connection by double-clicking the appropriate icon in the Dial-Up Networking window. When you then open up your Network Neighborhood window, you should see your server workgroup listed there. Your connection to the Internet needs to be established first before you initiate the PPTP connection. This may involve double-clicking one Dial-Up Networking icon to start your Internet connection, then double-clicking a second icon to start the PPTP connection.
If you are unable to establish a PPTP connection to your server, you should visit. Due to the dynamic nature of Microsoft's web site, the page may appear differently depending upon the version of Windows you are using. In most cases, you will want to look or search for Virtual Private Networking or a Dial Up Networking bit encryption update.
You may need to install the bit encryption update first , and then install the bit encryption update.
Note that with Microsoft's ActiveUpdate process, if you are not presented with the choice for this update, it is most likely already installed in your system. Another way to upload or download files to and from your server is to enable a protocol called FTP, or "file transfer protocol".
This screen enables you to set your policy for FTP. Note that allowing liberal FTP access to your server does reduce your security. You have two options that you can set here. FTP user account access: Private FTP access allows only people on your internal network to write files to your server. Public FTP access allows users both inside and outside your local network to read or write files on your server, provided they have an account and password. If, for example, you want to be able to update your web site from home using FTP, you would choose the "Public" setting.
We strongly recommend you leave this as Private unless you have a specific reason to do so. The setting you choose here will override all other FTP settings on your server. For example, if you choose "Disable public FTP access" here and then later configure an i-bay to allow public FTP access from the Internet, such access will be forbidden. Note that one of the choices here allows you to completely disable any use of FTP. This screen gives you the options to control the use of telnet as a means of connecting to your server.
Telnet can be useful in that it allows you to login remotely and diagnose problems or configure settings. However, when you use telnet, all user names and passwords are transmitted without any kind of encryption , dramatically reducing the security of your server. For that reason, we strongly recommend the use of ssh as described above.
Because telnet has been and continues to be widely used to date, we are providing the ability to use telnet for remote access. However, as ssh usage increases, it is our intention to remove telnet access from future releases of the server. Because of the inherent security weakness mentioned above, we strongly recommend that you leave this set to No Access the default and instead use ssh as described above. If you do need to enable telnet access, we suggest that you enable "public" or.
If "public" access is enabled, a red warning will appear at the top of every server manager screen. Because of these security concerns, we do not allow administrative command line access connecting as 'root' using telnet. Please use ssh instead. Your SME Server provides services to machines on the local network and it gives machines on that network special privileges and access.
For example, only machines connected to the local network can access the mail server on your server to send mail. When you configured your server, you provided it with sufficient information to deduce its own local network.
Machines on the network are automatically identified by the server as being eligible for these privileges and access. If your company only has one network that is being serviced by the server, you do not need to add any information here. Some advanced users may wish to extend privileges to more than one network of computers.
If you would like your server to identify one or more additional networks for those privileges, you will be asked to enter those network IDs and the subnet mask for each network here. Note that depending on the architecture of your network infrastructure, the instructions for configuring the client machines on that additional network may be different than the instructions outlined in the chapter in this user guide.
If you have questions regarding adding another network, you may wish to contact Contribs. Accessing this section allows you to set the system date and time either manually or using a network time server. Pull-down menus for month and time zone ensure accurate entry. The server manager will reset the time automatically during daylight savings time. There are worldwide time zones with multiple selections for countries with multiple time zones.
This ensures that regional variations in time zones and daylight savings time are accurately reflected. Instead of setting the time manually, you can use a network time server.
A time server is a device on the Internet that keeps accurate time and is able to communicate the time to other computers over the Internet using the Network Time Protocol NTP.
Many organizations around the world provide Internet time servers for free. After you start using a network time server, you should NOT set the time or date manually.
If you do so, the network time synchronization will no longer function. This screen in the server manager allows you to configure your server to connect regularly to a time server and synchronize the clock on the server with the time provided by the time server. Using a time server is optional but doing so can greatly increase the accuracy of your system. You should always use a secondary time server also called a stratum 2 server to lighten the load on the primary time servers.
In order to make sure the network time server is set to your timezone, you should go through this screen once and manually set the time to be correct and with the correct timezone. After doing that, go back to this panel and set the server to use a network time server.
If you are using a computer on a local network and you wish to access the server via Windows file sharing, it is important that you are logged onto the same workgroup as your SME Server. This screen allows you to enter the name of the Windows workgroup the server should appear in.
You should also enter the Windows server name. If you wish you can change the workgroup name to correspond with an existing workgroup. Macintosh users need only enter a server name or accept the defaults. Also in this section, you can specify whether the server should be the domain master for your Windows workgroup. Most sites should choose "Yes" unless you are adding an server to an existing network which already has a domain master. If you have a Windows NT server or Windows server on your network that is functioning as a network server, you should most likely answer "no" because that other server will act as the domain master.
This batch file is executed by Windows clients that have been configured to "Logon to domain". The netlogon. As the "admin" user, you will need to connect to the share or map a drive to it, by using the specific path:. The sample file contains a few examples of setting the system time for each machine and also for mapping a common drive for all Windows client.
Your SME Server provides an easy mechanism for creating a company directory. Each time you create or delete an e-mail account, your directory will be automatically updated with the new information.
In this section of the server manager, you specify the default directory information for new accounts - the user's department, company, street address, city and phone number. Each time you create an e-mail account, the fields will contain the information entered here as the default. If you wish, you can change the information for each user.
At any time in the future, you can change the default information and have the new information apply to all new users or to all existing users as well. The field to do this is located near the bottom of the screen. Choosing "update with new defaults" is a convenient one-click method of revising your directory when, for example, your company has moved to a new address.
Your SME Server enables all users on your network to easily share a printer. The printer can be either locally attached to a parallel or USB port on your server or can be a network printer. All the server needs is some basic information: the printer name which can be anything you want, as long as it starts with a lower-case letter and consists only of lower-case letters and numbers, with no spaces , a brief description for example, "the printer down the hall" and the location of the printer - whether it's on the network or directly connected to your server through a parallel or USB port.
If you choose "Network printer", you will see an additional screen that will ask for the hostname or IP address and the network printer name. Enter that information where requested. For the network printer name, you can use the default setting, raw , unless you have some reason to do otherwise. For maximum flexibility in making changes later, we suggest that you enter the hostname for a network printer here and enter the IP address of the printer through the Hostnames and addresses panel of the server manager.
This allows you to have one central location listing IP addresses and allowing you to make changes. Note that many modern network printers can be configured automatically. To do so, enter their hostname, IP address and Ethernet address in the Hostnames and addresses panel.
Note also that the server printing system does not perform any filtering and passes the print requests directly from the client computers to the printer in the "raw" or "pass-through" machines. For this reason, the SME Server does not have a list of "supported printers". Most printers are supported as long as the appropriate driver is installed in the operating system on your client computers.
However, there are some newer printers that only have a Windows driver available and rely heavily on that operating system to perform their print functions. These printers cannot be used on the server. If you are concerned about whether your printer will work with your server, you can visit Red Hat's Hardware Compatibility List or explore the information found at LinuxPrinting.
As a final item, you should be aware that in order to use the printers available through your server a user must be logged in to their client system with a user name and password that is valid on the server. For instance, if a user is logged in as tturtle on their Windows desktop and that user account does not exist on the server, the user will not be able to print to the printers managed by the server.
Either the user will have to logout and log back in as a valid user or the tturtle. When you installed your SME Server, you were asked to provide a name for your system.
That name and several other "standard" names are automatically configured in your system's host table during the installation process. This host table is consulted as part of the name resolution process. The "Hostnames and address" web panel allows you to modify this table and specify different host "names" for each domain on your system, as well as to control how those names resolve both for systems on your local network and also for systems on the larger Internet.
For instance, when someone tries to connect to " www. As seen in the image below, this screen in the server manager allows you to view these default settings, and also to modify the configuration. Throughout the screens linked to from the Hostnames panel, you will find the text "Publish globally? Suppose, for example, your company's web site was hosted at some other location, such as on your ISP's web servers. If you wanted " www. The image below shows the screen in which you would perform the task:.
Creating new hostnames simply involves selecting one of the links at the top of the Hostnames and addresses panel and filling out the appropriate fields. Note that if your system is configured with any virtual domains , you will have the choice of the domain in which you want to create the hostname.
This allows you, for instance, to have " www. Additional names for your server: For instance, you might want to set up "intranet.
All you do here is enter the hostname and, if appropriate, choose the domain for the hostname. Remote hosts: As mentioned in the example earlier, you might want to point a hostname such as "www" to a remote system. While "www" is created by default, you can create other names such as "home", "research", or any other appropriate name.
In the form, you simply enter the hostname, choose the domain, and enter the remote IP address. Local hosts: This screen is a bit more complicated because you have more options. At a basic level, you can create a hostname in a domain that points to another computer on your local network.
For instance, you might want "research" to point to a computer system inside your network. Where this gets complicated is when you want "research. The challenge is that your local IP addresses are only accessible inside your network. For that reason, the target computer system will need to have two network interface cards - one connected to the internal network and one connected to the external network.
The "Ethernet address" field when creating a hostname pointing to a local host is only used for reserving IP addresses through DHCP as mentioned in the next section. Another task you can perform through this panel is to reserve an IP address for a given system based on its Ethernet address. For instance, you might have another intranet web server within your company that you want to always have the same IP address. One method of assigning that address is to manually configure the client machine to have a static IP address.
The negative aspect of doing this is that if you later want to change the network settings for that machine, you must manually go and configure that machine. Additionally, you have to keep track somewhere of the fact that you have assigned a specific IP address to that machine. Rather than configuring the machine manually, you can reserve an IP address from the DHCP server for that specific machine.
This has the same result as manually configuring a static IP address, but offers two benefits. First, you have one location to keep track of all assigned static address. Second, through the DHCP server you will provide network settings. If you wish to change those settings, the change can be simply done on your server. To reserve an IP address, you must first determine the Ethernet address of your client system.
Once you have determined the client's Ethernet address, click on the link to create a new hostname for a local host. Add the hostname of the target system, the Ethernet address along with the desired IP address into the web panel. From this point on specified IP address will only be provided to a client system with the matching Ethernet address. As shown below, this section of the server manager allows you to specify the protocol used to retrieve e-mail from your ISP and configure other settings regarding the retrieval of e-mail.
Your choice of e-mail retrieval mode will depend on the arrangements you made with your Internet service provider:. This secondary mail server will provide temporary e-mail storage when your server is not connected to the Internet. If you arranged "multidrop" mail service from your ISP , choose "multidrop" and then scroll down to the field that asks for the IP address or hostname of your ISP's secondary mail server.
This secondary mail server will receive all e-mail for your domain and store it in a single POP mailbox. Further down the screen, you will need to specify the user account and password assigned by your ISP for this POP mailbox.
Your server will periodically fetch this mail and distribute it to individual POP mailboxes on the server. Note that due to problems receiving mail for mailing lists, we strongly encourage people to. If you want to forward e-mail to another mail server for processing , enter the mail server IP address in the box marked Delegate mail server.
A common use for this is if your server is receiving inbound e-mail from the Internet, but you would like to pass that mail to a different mail server on your internal network. If you have a dialup connection, the server allows you to control how frequently it fetches e-mail from your ISP.
This is particularly useful in situations where you incur phone or Internet charges each time your system contacts your ISP.
The default settings are every 15 minutes during standard office hours and every hour outside normal office hours on weekdays or on weekends. The fields allow you to customize those settings.
Finally, if you have "multidrop" mail service you need to select the sort method used by the server to decide which user each message should be delivered to. Your server has a default method for this it examines various headers such as "To" and "Resent-To" which works in most circumstances but is not suitable for certain purposes such as mailing list messages.
Some ISPs add a header to each e-mail message which can help your server determine the correct recipient. If your ISP does not add a header to multidrop e-mail, select the "Default". Because you will experience problems with mailing-lists when using multi-drop e-mail, we strongly recommend that you work with your ISP to have a special header added to each message. The "Default" sort method should be only used as a last resort. This screen presents you with additional options for controlling how your system handles e-mail.
Forwarding address for administrative notices: The default address for administrative notices i. If you'd like those messages to be sent elsewhere, enter the address here. Be aware that all messages sent to postmaster , root or mailer-daemon at your domain are sent to either admin or the address that you enter in this field.
E-mail to unknown users: This field allows you to choose whether incoming messages to unknown users are bounced back to the sender or forwarded to the system administrator. Some users prefer the latter setting because it allows them to catch and reroute e-mail that was incorrectly addressed.
If you choose to have messages forwarded to the system administrator, they will be sent to either "admin" or the e-mail address specified in the forwarding address field mentioned above. Internet provider's SMTP server: Normally the server will send outgoing messages directly to their intended destination.
If, however, you have an unreliable connection or are using a residential Internet service, it may be advisable to route e-mail via your provider's SMTP server. In fact, if you have a temporary dial-up connection to the Internet, you may find that you need to use your ISP's mail server in order to deliver mail to some locations.
