This option takes both group names and usernames. In addition, you can specify NIS netgroups by preceding them with an as well; if the netgroup is not found, Samba will assume that you are referring to a standard Unix group. Be careful if you assign an entire group administrative privileges to a share. The Samba team highly recommends you avoid using this option, as it essentially gives root access to the specified users or groups for that share.
If you wish to force read-only or read-write access to users who access a share, you can do so with the read list and write list options, respectively. These options can be used on a per-share basis to restrict a writable share or grant write access to specific users in a read-only share, respectively. The write list option cannot override Unix permissions. If you've created the share without giving the write-list user write permission on the Unix system, he or she will be denied write access regardless of the setting of write list.
As mentioned earlier, you can specify users who have guest access to a share. The options that control guest access are easy to work with. The first option, guest account , specifies the Unix account that guest users should be assigned when connecting to the Samba server. The default value for this is set during compilation, and is typically nobody. However, you may want to reset the guest user to ftp if you have trouble accessing various system services.
If you wish to restrict access in a share only to guests - in other words, all clients connect as the guest account when accessing the share - you can use the guest only option in conjunction with the guest ok option, as shown in the following example:.
Make sure you specify yes for both guest only and guest ok in this scenario; otherwise, Samba will not use the guest acount that you specify. Table 6. This option specifies a list of users that perform file operations as if they were root. This means that they can modify or destroy any other user's work, no matter what the permissions. Any files that they create will have root ownership and will use the default group of the admin user.
The admin users option is used to allow PC users to act as administrators for particular shares. We urge you to avoid this option. These two options let you enumerate the users and groups who are granted or denied access to a particular share. You can enter a list of comma-delimited users, or indicate an NIS or Unix group name by prefixing the name with an at-sign. The important rule to remember with these options is that any name or group in the invalid users list will always be denied access, even if it is included in any form in the valid users list.
By default, neither option has a value associated with it. If both options have no value, any user is allowed to access the share. Like the valid users and invalid users options, this pair of options specifies which users have read-only access to a writeable share and read-write access to a read-only share, respectively.
The value of either options is a list of users. You can specify NIS or Unix group names by prefixing the name with an at sign such as users. Neither configuration option has a default value associated with it. This option specifies the maximum number of client connections that a share can have at any given time. Any connections that are attempted after the maximum is reached will be rejected.
The default value is 0 , which means that an unlimited number of connections are allowed. Use a comma-separated list to deny share access to multiple accounts. Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. Runs the cmdlet in a remote session or on a remote computer. The default is the current session on the local computer.
Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
Specifies the maximum number of concurrent operations that can be established to run the cmdlet. The throttle limit applies only to the current cmdlet, not to the session or to the computer. The Microsoft. The path after the pound sign provides the namespace and class name for the underlying WMI object. I'm not understanding how that restricts access to I'm sure what you posted will work, I just don't understand how it works.
Sorry to be a pain, I'm just trying to learn as much as I can. Edit: I think fukawi2's example are fine, I forgot to look a the "deny" section. You might consider reading this article about network addressing to understand how CIDR notation works. It should make total sense once you understand how network addressing works.
Also, there are CIDR to iprange converters available via webapps, as well as some console-based ones such as "ipcalc" available in the arch repositories. Sorry fukawi2, I forgot to look at the "deny" line, when I was calculating things. No problem, just wanted to make sure I wasn't missing something.
