Host-Specific Subconfiguration

The HostSpecifiConfig variable specifies host-specific subconfiguration files for sshd2. The syntax is the following:

HostSpecificConfig pattern subconfig-file

pattern will be used to match the client host as specified under AllowHosts (see the sshd2_subconfig man page). The file subconfig-file will then be read, and configuration data amended accordingly.

The file is read before any actual protocol transactions begin, and you can specify most of the options allowed in the main configuration file. You can specify more than one subconfiguration file, in which case the patterns are matched and the files read in the order specified. Later defined values of configuration options will either override or amend the previous value depending on which option it is. The effect of redefining an option is described in the documentation for that option. For example, setting Ciphers in the subconfiguration file will override the old value, but setting AllowUsers will amend the value.

For more information, please see the sshd2_subconfig and sshd2_config man pages.
