ident2 [options]


ident2 is an advanced ident daemon, which can run as an inetd service or on it's own. It has various features such as user defined and random replies, extensive logging, and full administrative control.


The program follows the usual GNU syntax command-line unless it is unsupported on your system. GNU options begin with two dashes(`-') and have much more descriptive names.

-a, --force-inetd

Force inetd mode, if autodetection isn't working.

-d, --force-daemon

-i, --use-user-ident

Allow user defined ident replies. Just do a echo 'ident ar' > ~/.ident to change your ident reply.

-y, --user-reply-file

File ident2 should look for in user's homedir for replies. Default is ~/.ident

-n, --allow-noident-file

Disable replies for user if user has a ~/.noident file. This behavior is disabled by default.

-o, --client-timeout

Clients timeout after this many seconds

-s, --dont-change-uid

Ident2 will normally try to change it's uid to something less privileged if it finds it's uid to be 0. This option disables this behavior altogether.

-r, --always-random

Always send a random reply, regardless of what kind of request the client made. This is useful for abusing the ident protocol as well as assisting outgoing IP masqueraded connections.

-m, --daemon-maxclients

Daemon-only: Accept no more than this many connections at a time.

-p, --daemon-port

Daemon-only: Bind this port, instead of 'auth' aka 113
