identd(1M) identd(1M)

-n The -n ﬂags tells identd to always return user numbers instead of user names if you wish to

keep the user names a secret.

-N The -N ﬂag makes identd check for a ﬁle .noident in each homedirectory for a user which

the daemon is about to return the user name for. It that ﬁle exists then the daemon will give the

error HIDDEN-USER instead of the normal USERID response.

-m The -m ﬂag makes identd use a mode of operation that will allow multiple requests to be pro-

cessed per session. Each request is speciﬁed one per line and the responses will be returned one

per line. The connection will not be closed until the connecting part closes it’s end of the line.

Please note that this mode violates the protocol speciﬁcation as it currently stands.

-d The -d ﬂag enables some debugging code that normally should NOT be enabled since that

breaks the protocol and may reveal information that should not be available to outsiders.

kernelfile kernelﬁle defaults to the normally running kernel ﬁle.

kmemfile kmemﬁle defaults to the memory space of the normally running kernel.

INSTALLATION

identd is invoked either by the internet server (see inetd(1M)) for requests to connect to the IDENT port

as indicated by the

/etc/services

ﬁle (see services(4)) when using the -w

or -i modes of operation or

started manually by using the

-b mode of operation.

EXAMPLES

Since the server is located in /usr/lbin/identd

one can put either:

ident stream tcp wait bin /usr/lbin/identd identd -w -t120

or:

ident stream tcp nowait bin /usr/lbin/identd identd -i

into the /etc/inetd.conf ﬁle.

To start it using the unsupported

-b mode of operation one can put a line like this into the

/sbin/init.d/sendmail

ﬁle under the ’start’ section:

/usr/lbin/identd -b -u2 -g2

This will cause identd to be started as daemon whenever sendmail is running. It will run in the back-

ground as user 2, group 2 (user ’bin’, group ’bin’).
