The client currently can not use rsize larger than CIFSMaxBufSize. CIFSMaxBufSize defaults to 16K and may be changed (from 8K to the maximum kmalloc size allowed by your kernel) at module install time for cifs.ko. Setting CIFSMaxBufSize to a very large value will cause cifs to use more memory and may reduce performance in some cases. To use rsize greater than 127K (the original cifs protocol maximum) also requires that the server support a new Unix Capability flag (for very large read) which some newer servers (e.g. Samba 3.0.26 or later) do. rsize can be set from a minimum of 2048 to a maximum of 130048 (127K or CIFSMaxBufSize, whichever is smaller). The Common Internet File System (CIFS) is a network file-sharing protocol. CIFS is a form of SMB. Installing CIFS utilities on Ubuntu and Debian: sudo apt update sudo apt install cifs-utils Installing CIFS utilities on CentOS and Fedora: sudo dnf install cifs-utils The package name may differ between Linux distributions.To verify that the remote Windows share is successfully mounted, use either the mount or df -h command. Once the share is mounted, the mount point becomes the root directory of the mounted file system. You can work with the remote files as if they were local files.To get a list of all mount options type man mount in your terminal. The line must include the hostname or the IP address of the Windows PC, the share name, and the mount point on the local machine. Next time you reboot the system, the Windows share will be mounted automatically. The umount command will fail to detach the share when it is in use.

upcall gets the hostname but if I check the DNS records A,PTR seem to be ok. And netbios resolution does also work. Does it extract the hostname out of the UNC-Path. Nevertheless another server with the same windbind, samba, cifs.upcall and kerberos Version does work. The resolv.conf has also the same entries. There are some other samba-shares that work perfectly with kerberos. So I am a little bit stuck now. Any help would be appreciated. Now it works! The -t Option does the following: With krb5 upcalls, the name used as the host portion of the service principal defaults to the hostname portion of the UNC. Let us know so we can fix it. When the Windows server is configured to not allow SMBv1 the. Windows server will send a TCP RST to the Negotiate Protocol. Request sent from the SLES server with an SMBv1 header. This is to be expected. This TCP RST results in an. This protocol is used by Windows for network shares and shared printers.This is an outstanding tool for ensuring seamless integration of Linux servers and the office desktop machines still running Windows.This book only focuses on the use case where Samba is used as a standalone server, but it can also be a NT4 Domain Controller or a full Active Directory Domain Controller, or a simple member of an existing domain (which could be a managed by a Windows server).Winbind also integrates cleanly with PAM and NSS. This allows setting up Linux machines where all users of a Windows domain automatically get an account.The Falcot Corp administrators rejected this option, since they intend to use the Samba server itself as the WINS server.This option has been removed from the default configuration in Buster and must be added manually if desired.Each user must authenticate before accessing any share.The Unix step is done quite normally (using adduser for instance).A Samba account can also be temporarily disabled (with smbpasswd -d user ) and re-enabled later (with smbpasswd -e user ).

The required programs are available in the cifs-utils and smbclient packages.It accepts a -U user option, for connecting to the server under a specific identity.Two options in particular can be interesting: uid and gid allow forcing the owner and group of files available on the mount, so as not to restrict access to root.When the smbclient is installed, CUPS allows installing Windows shared printers automatically.It should look like the following:Then enter the description and location of the printer. Those are the strings that will be shown to end users to help them identify the printers. It is sufficient to proceed with the preceding operation on one host. The Storage Repository should now be created for the whole pool or for a single host, if there is only a single host used without the pool. This can be especially true when operating in environments that either have a large Microsoft Windows footprint, or in a legacy application that has been containerized. A mechanism to communicate with Windows storage backends is through CIFS (Common Internet File System), an implementation of the SMB (Server Message Block) protocol. Even though OpenShift does not have direct support for CIFS as a volume plug-in, storage backends, such as CIFS, can still be accessed through an alternative plug-in type called FlexVolumes. A diagram of the architecture can be found below: Since SELinux is enabled on all machines in the cluster, additional options need to be provided at mount time to properly label the directory used to mount the share with the appropriate security content, thus enabling containers running within pods the ability to access the file system. While it could have been possible to require this mount option parameter to be specified by end users, improper configuration would result in runtime errors, thus the entire process was abstracted.

Instead of specifying the username, password and optional domain inline as mount options, these values are instead stored in a file that can only be read by the root user and referenced as a mount option. Finalize the installation by restarting the OpenShift node service. The Ansible assets are located within the project repository in a folder called ansible where a single playbook called setup-openshift.yml and an inventory file can be found. Since the driver is to be installed on all OpenShift nodes, a single nodes group is used. If the inventory file from the OpenShift installation is available, it can be used instead. Otherwise, fill in the inventory with the OpenShift nodes and then run the playbook However, by default, the FlexVolumes plugin is not available for most users. The ability to leverage a volume plugin is defined within one of the security features of OpenShift, Security Context Constraints. When a typical user launches a pod in OpenShift, the pod is associated with the restricted SCC. Aside from a limited number of volume plugins that can be used, the most common trait is that containers will run with a randomly assigned user ID. To enable FlexVolumes for users within an OpenShift environment, it is recommended that a custom SCC be created instead of modifying the built in types.

Since the desired functionality is to retain the remaining security features employed in OpenShift by default, and add a new available volume plugin, as a cluster administrator, export the existing restricted SCC to a file: Locate this property, remove system:authenticated and replace it with an empty array as shown below: Add the following to the list of enabled plugins: First, create a new project called “cifs-flexvolume-demo”: Execute the following command to grant the default service account in the cifs-flexvolume-demo project access to the restricted-flexvolume SCC: Credentials are stored as a secret, declared within the volume definition and exposed to the driver at mount time. An OpenShift template called cifs-secret-template.yml is available in the examples folder to help streamline the secret creation process. Execute the following command passing in the appropriate credentials for the CIFS share in the following command: The application consists of a simple Red Hat Enterprise Linux container that has been configured with a sleep loop to help it remain up and active. The goal is for you to be able to use a remote terminal to explore the container file system and confirm the ability to access the CIFS share. A template called application-template.yml is also available in the examples folder. Open the template file and take note of the volumes section: Review the default parameters (where available) at the bottom of the file. If the volume mounted successfully, the pod will transition into a Running state. Otherwise, it will remain with a status of ContainerCreating. If there were issues mounting the share, by executing an “ oc describe ”, a timeout error waiting for the volume to attach to the container would be shown.

Since the actual mounting occurs on the node where the container is ultimately being run, inspecting the journald logs for the atomic-openshift-node service will most likely identify the ultimate cause of any issues: Obtain a remote shell session within the container by first locating the name of the running pod and starting the remote session: Given the fact that CIFS is a shared file protocol, it enables the use of a storage type that is common in many applications and expands the footprint of applications that can be utilized within OpenShift. Serverless is a great.Tired of cutting and pasting pieces of output to create new kubectl and oc commands. If you answered yes, take a look at the Visual Web.Red Hat is. This driver allows for the creation of a PersistentVolume or direct mount to access storage that is exposed by a CIFS share. Tehe vendor for this driver is openshift.io and the driver name is called cifs.The inventory groups align with the group names utilized in the OpenShift installation meaning that inventories created for existing environments can be utilized. Otherwise, fill out the nodes group with the instances that are desired to be configured with the CIFS FlexVolume driver. Credentials to access CIFS volumes can be placed in a secret and then referenced in the FlexVolume definition. If desired, add the domain key to the secret. FlexVolumes are not one of the allowed volume types. Instead of modifying the existing restricted SCC, it is recommended that a custom SCC be created instead. An example of an SCC based upon the restricted SCC with support for FlexVolume's is provided in the examples folder called restricted-flexvolume-scc.yml. The following example describes how to grant the default service account to the custom SCC. An example is defined below: In addition, it is recommended (almost required) that the above mountOptions be specified in order to comply with OpenShift's security model.

You may override this with a different context, however it is no recommended. However, due to the combination of OpenShift's security requirements, as well as the architecture of the controller-manager, it became necessary for another implementation to be created.

Depending on the length of the content, this process could take a while. BUT, for many of us, having to deal with Windows is a fact of life. For example, you may want to use a Linux server to back up Windows files. This can be made easy by mounting Windows shares on the server. You will be accessing Windows files as if they are local and essentially all Linux commands can be used. Mounting Windows (or other samba) shares is done through the cifs virtual file system client (cifs vfs) implemented in kernel and a mount helper mount.cifs which is part of the samba suite. The following names are used in our examples.Note that cifs-utils is for CentOS-6 (or later) only. Use of the uid flag is optional. However, it may be required for certain applications (for example, Acrobat) to work because they are picky about the permissions. You may want to use different options for cifs. For example, nocase allows case insensitive path name matching.Username and password are visible to everyone. Encrypted passwords cannot be used. Make sure it is not readable by others.This might cause problems if the remote share becomes unavailable, resulting in stale mounts.
