smbctune.conf File

Purpose

Contains the tunable parameter settings that are associated with the Server Message Block (SMB) client file system.

Description

The /etc/smbc/smbctune.conf file contains the tunable parameters and its corresponding values that are used by the smbctune command. The smbcd daemon makes the tunable parameter changes persistent.

This file contains the same tunable parameters as specified by the smbctune command. By default, the format of the /etc/smbc/smbctune.conf file is as follows:

default:
        smbc_lookup_cache_size=32
        smbc_max_concurrent_mount=8
        smbc_max_connections=0
        smbc_request_timeout=0
        smbc_krb5_lifetime=0
        smbc_krb5_renew_till=0
        smbc_oplock_enable=1
        smbc_file_lease_enable=1
        smbc_protocol_version=auto
        smbc_signing=enabled
        smbc_secure_negotiate=desired
        smbc_encryption=desired

The default keyword must be used to indicate that the same tunable parameters are applicable for each SMB client system that connects to the SMB server.

Example

To set the maximum number of concurrent mount operations to 1024, the number of maximum available connections on the SMB client system to 4096, and the request timeout duration to 20 seconds, enter the following text in the smbctune.conf file:
```
default:
  smbc_request_timeout=20
  smbc_max_concurrent_mount=1024
  smbc_max_connections=4096
```
