Capabilities

Capabilities allow the system administrator to control the set of features users have access to. They can be granted or revoked using capability directives. No capabilities are granted to users by default.

forward

The forward capability allows users to forward Ident queries to another server. The host and port arguments specify the host and port of the receiving Ident server. This server must support forwarding (e.g., oidentd with the --proxy option).

Forwarding does not allow users to send replies they otherwise would not be able to send. For example, if the receiving Ident server replies with the name of another user, the reply will be sent back to the client only if the user that owns the connection was granted the spoof and spoof_all capabilities. This restriction does not apply to force forward statements in the system-wide configuration file.

Imperative syntax: forward <host> <port>

hide

The hide capability allows users to hide their connections. When used, oidentd reports a HIDDEN-USER error to clients.

Imperative syntax: hide

numeric

The numeric capability allows users to reply with their user ID (UID) instead of their user name.

Imperative syntax: numeric

random

The random capability allows users to send random alphanumeric Ident replies. Replies are logged so that the system administrator can identify the user responsible for a particular connection.

Imperative syntax: random

random_numeric

The random_numeric capability allows users to send random numeric Ident replies of the form userNNNNN, where N represents a digit from 0 to 9. Replies are logged so that the system administrator can identify the user responsible for a particular connection.

Imperative syntax: random_numeric

reply

The reply capability cannot be granted or revoked. However, using it may require one or more of spoof, spoof_all, and spoof_privport, depending on the replies and type of connection.

If more than one reply is given, a random reply is chosen from the list for each incoming query. At least one reply must be specified.

Imperative syntax: reply <replies ...>

spoof

The spoof capability allows users to send custom Ident replies, except in cases that require the spoof_all or spoof_privport capabilities.

This capability does not have an imperative syntax.

spoof_all

The spoof_all capability allows users to reply with the names of other users on the system. It only works in conjunction with the spoof capability.

This capability does not have an imperative syntax.

spoof_privport

The spoof_privport capability allows users to spoof replies for connections to privileged foreign ports (port numbers below 1024). It only works in conjunction with the spoof capability.

This capability does not have an imperative syntax.
