identd(1M)identd(1M)NAMEidentd - TCP/IP IDENT protocol server
SYNOPSIS
seconds] seconds] uid] gid] port] address] charset]
DESCRIPTION
is a server which implements the TCP/IP proposed standard IDENT user
identification protocol as specified in the RFC 1413 document.
operates by looking up specific TCP/IP connections and returning the
user name of the process owning the connection.
Options
The protocol server recognizes the following options:
Specify the local address to bind the socket to if using
the mode of operation. Can only be specified by the IP
address and not by the domain name. The default value in
IPv4 is and in IPv6 is which normally represents all the
local addresses.
Run in standalone mode without
assistance from This mode is the least preferred mode and not
supported by HP. A bug or any other fatal condition in the
server will make the server terminate, and it will then have
to be restarted manually.
Add the optional (according to the IDENT protocol) character set
designator to the reply generated. charset should be a valid
character set as described in the MIME RFC in uppercase char‐
acters.
Enable some debugging code that normally should
be enabled since it breaks the protocol and may reveal infor‐
mation that should not be available to outsiders.
Always return
instead of the or errors.
Specify a group id number which the
server should switch to after binding itself to the TCP/IP
port if using the mode of operation.
Default mode.
This mode should be used when starting the daemon from with
the "nowait" option in the file. Use of this mode will make
start one daemon for each connection request.
Use the system logging daemon
for logging purposes.
Use a mode of operation that allows multiple requests to be
processed 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 its end of the line.
Always return user numbers instead of user names in order to
keep the user names a secret.
Check for a file
in each home directory for a user which the daemon is about
to return the user name for. If that file exists then the
daemon will give the error instead of the normal response.
Do not reveal the operating system type it is run on and always return
instead.
Specify an alternative port number to bind to if using
the mode of operation. The port can be specified by name or
by number. It defaults to the IDENT port (113).
Used to specify the timeout limit.
This is the number of seconds a server started with the flag
will wait for new connections before terminating. The server
is automatically restarted by whenever a new connection is
requested if it has terminated. A suitable value for seconds
is 120 (two minutes), if used. It defaults to no timeout.
That is, it will wait forever, or until a fatal condition
occurs in the server.
Specifies the maximum number of seconds a server will wait for the
client's input before closing the connection on timeout. By
default, the timeout limit is 0 (zero); that is, the server
waits for an indefinite amount of time. This option is
ignored for invalid timeout intervals.
Specify a user id number which the
server should switch to after binding itself to the TCP/IP
port if using the mode of operation.
Display the version number and exit.
Use this option when starting the daemon from
with the "wait" option in the file. The daemon will either
run forever or until a timeout, as specified by the flag,
occurs.
INSTALLATION
is invoked either by the internet server (see inetd(1M)) for requests
to connect to the IDENT port as indicated by the file (see services(4))
when using the or modes of operation or started manually by using the
mode of operation.
WARNINGS
The and options are currently not supported on HP-UX.
EXAMPLES
Assume the server is located in Add either of the following two lines
into the file:
or:
To start using the unsupported mode of operation, add the following
line to the file under the start section:
This will cause to be started as daemon whenever is running. It will
run in the background as user 2, group 2 (user group
