DESCRIPTION
identd is a server which implements the TCP/IP proposed standard IDENT user identification protocol
as specified in the RFC 1413 document.
identd operates by looking up specific TCP/IP connections and returning the user name of the process
owning the connection.
Arguments
-i The -i flag, which is the default mode, should be used when starting the daemon from
inetd
with the "nowait" option in the
/etc/inetd.conf
file. Use of this mode will make inetd
start one identd daemon for each connection request.
-w The -w flag should be used when starting the daemon from
inetd with the "wait" option in
the
/etc/inetd.conf
file. The identd daemon will run either forever, until a timeout, as
specified by the
-t flag, occurs.
-b The -b flag can be used to make the daemon run in standalone mode without the assistance
from inetd. This mode is the least preferred mode, and not supported by HP, since a bug or
any other fatal condition in the server will make it terminate and it will then have to be res-
tarted manually.
-tseconds
The -tseconds option is used to specify the timeout limit. This is the number of seconds a
server started with the -w flag will wait for new connections before terminating. The server is
automatically restarted by inetd whenever a new connection is requested if it has ter-
minated. A suitable value for this is 120 (2 minutes), if used. It defaults to no timeout. That is,
it will wait forever, or until a fatal condition occurs in the server.
-uuid The -uuid option is used to specify a user id number which the
ident server should switch to
after binding itself to the TCP/IP port if using the
-b mode of operation.
-ggid The -ggid option is used to specify a group id number which the
ident server should switch
to after binding itself to the TCP/IP port if using the
-b
mode of operation.
-pport The -pport option is used to specify an alternative port number to bind to if using the
-b
mode of operation. It can be specified by name or by number. Defaults to the IDENT port
(113).
-aaddress
The -aaddress option is used to specify the local address to bind the socket to if using the -b
mode of operation. Can only be specified by the IP address and not by the domain name. The
default value in IPv4 is INADDR_ANY, and in IPv6 it is in6addr_any, which normally
represents all the local addresses.
-V The -V flag makes identd display the version number and the exit.
-l The -l flag tells identd to use the System logging daemon syslogd for logging purposes.
-o The -o flag tells identd to not reveal the operating system type it is run on and to instead
always return "OTHER".
-e The -e flag tells identd to always return UNKNOWN-ERROR instead of the NO-USER or
INVALID-PORT errors.
-ccharset The -ccharset flags tells identd to add the optional (according to the IDENT protocol) char-
acter set designator to the reply generated. <charset> should be a valid character set as
described in the MIME RFC in upper case characters.
-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 home directory for a user
which the daemon is about to return the user name for. It that file exists then the daemon will
