NAME Net::Ident - lookup the username on the remote end of a TCP/IP connection SYNOPSIS use Net::Ident; $username = SOCKET->ident_lookup($timeout); ($username, $opsys, $error) = SOCKET->ident_lookup($timeout); $obj = Net::Ident->initconnect(SOCKET, $timeout); $fh = $obj->getfh; $obj->query; $status = $obj->ready; $username = $obj->username; ($username, $opsys, $error) = $obj->username; use Net::Ident 'lookup'; $username = lookup(SOCKET, $timeout); ($username, $opsys, $error) = lookup(SOCKET, $timeout); OVERVIEW Net::Ident is a module that looks up the username on the remote side of a TCP/IP connection through the ident (auth/tap) protocol described in RFC1413 (which supersedes RFC931). Note that this requires the remote site to run a daemon (often called identd) to provide the requested information, so it is not always available for all TCP/IP connections.
