libident binary package in Ubuntu Bionic s390x

 This is a small library to interface to the Ident protocol server;
 "ident" enables a remote host to find out who's the owner of a
 network connection.
 .
 /usr/sbin/in.identtestd is a small daemon (to be started from inetd)
 that does an ident lookup on you if you telnet into it. Can be used
 to verify that your Ident server is working correctly.
