nutcpc-dbgsym binary package in Ubuntu Xenial s390x

 NuFW is an authenticating firewall based on netfilter's NFQUEUE target.
 It allows one to write filtering rules based on user identity, in addition
 to classical network criteria. Unless other solutions, NuFW uses a
 strict security model and can apply different access rules to users
 connected on the same host, for example.
 .
 nutcpc is a console-mode client for the NUFW authenticating firewall.
 It is in charge of authenticating the user, and replying to nuauth requests
 to send information on network connections.
