Now all I remember is the pain. Why would a Workgroup show up? The ghosts of Windows 3. The Network icon in my File Explorer stubbornly only showed my laptop.
Still a no go. Finally another Google search and saw a recommendation to try connecting to the Samba share by using the ip address. I was in. I recently impulse purchased a pack of NFC tags from Amazon. Here is how to calculate the minimum number of backup browsers that will be allocated on a workgroup:.
There is currently no upper limit on the number of backup browsers that can be allocated by the local master browser. Browsing is a critical aspect of any Windows workgroup.
However, not everything runs perfectly on any network. At this point the Windows NT Workstation in the spare parts department might agree to take over the job. However, that computer is currently running a large, poorly written program that has brought its processor to its knees. The moral: browsing has to be very tolerant of servers coming and going.
Because nearly every Windows system can serve as a browser, there has to be a way of deciding at any time who will take on the job. This decision-making process is called an election.
An election algorithm is built into nearly all Windows operating systems such that they can each agree who is going to be a local master browser and who will be local backup browsers. An election can be forced at any time. As the server comes online, it will announce its presence, and an election will take place to see if the PC in the spare parts department should still be the master browser.
When an election is performed, each computer broadcasts information about itself via datagrams. This information includes the following:. These values determine which operating system has seniority and will fulfill the role of the local master browser.
Chapter 7 describes the election process in more detail. The architecture developed to achieve this is not elegant and has built-in security problems. While a browsing domain can be integrated with domain security, the election algorithm does not take into consideration which computers become browsers. Thus it is possible for any computer running a browser service to register itself as participating in the browsing election and after winning being able to change the browse list.
Nevertheless, browsing is a key feature of Windows networking, and backward-compatibility requirements will ensure that it is in use for years to come. The Windows password functions in a manner that might be a source of confusion for Unix system administrators. It is not there to prevent unauthorized users from using the computer. Instead, the Windows password is used to gain access to a file that contains the Windows Networking and network resource passwords.
This file is encrypted using the Windows password as the encryption key. As a security measure, you might want to check for junk. The first time the network is accessed, Windows attempts to use the Windows password as the Windows Networking password.
If this is successful, the user will not be prompted for two separate passwords, and subsequent logins to the Windows system will automatically result in logging on to the Windows network as well, making things much simpler for the user.
Shared network resources in the workgroup can also have passwords assigned to them to limit their accessibility. The first time a user attempts to access the resource, she is asked for its password, and a checkbox in the password dialog box gives the user the option to add the password to her password list. This will be discussed further in Chapter 9.
The peer-to-peer networking model of workgroups functions fairly well as long as the number of computers on the network is small and there is a close-knit community of users. However, in larger networks the simplicity of workgroups becomes a limiting factor. Workgroups offer only the most basic level of security, and because each resource can have its own password, it is inconvenient to say the least for users to remember the password for each resource in a large network. Even if that were not a problem, many people find it frustrating to have to interrupt their creative workflow to enter a shared password into a dialog box every time another network resource is accessed.
To support the needs of larger networks, such as those found in departmental computing environments, Microsoft introduced domains with Windows NT 3. A Windows NT domain is essentially a workgroup of SMB computers that has one addition: a server acting as a domain controller see Figure A domain controller in a Windows NT domain functions much like a Network Information Service NIS server in a Unix network, maintaining a domain-wide database of user and group information, as well as performing related services.
The responsibilities of a domain controller are mainly centered around security, including authentication , the process of granting or denying a user access to the resources of the domain. This is typically done through the use of a username and password.
Security identifiers are used to represent objects in the domain, which include but are not limited to users, groups, computers, and processes. The number after the rightmost hyphen is called a relative identifier RID and is a unique number within the domain that identifies the user, group, computer, or other object. However, ACLs are more versatile. To access the Samba share from Windows Explorer, start typing the IP address to our share in the search area.
I am using the hostname of the Samba server. In my case, it is centos. You can also access the share by using the IP address of the Samba server. You might be prompted to enter the username and password to access the share if you skipped the local user creation process. If you get prompted for credentials, enter the Samba username and password we created in the previous article.
You will need to enter the Samba share path every time you want to access the share. There is a better way to access the share by mapping a drive to Samba share in Windows.
Accessing a Samba share on Linux and Windows is easy. With this basic setup, you will be able to access file shares from client machines in your network. With somewhat more configuration, you can deploy Samba shares in a domain environment. Samba can do more than file share. If you would like to learn more about Samba, read this article about Windows and Linux interoperability.
This is a basic set up, but you can do so much more with Samba. Take a skills assessment today. When he is not playing in the CLI, you will find him playing Cricket. More about me. Relive our April event with demos, keynotes, and technical sessions from experts, all available on demand.
