This works for me;
nmap -sU -sT -p T:22-80,U:22-80 volcanobase

Not shown: 127 closed ports
PORT   STATE         SERVICE
22/tcp open          ssh
25/tcp open          smtp
53/tcp open          domain
80/tcp open          http
88/tcp open          kerberos-sec
53/udp open|filtered domain
88/udp open|filtered kerberos-sec
