Hi thanks Roger. Well I'm just using Ubuntu Server 16.04 LTS I only ran that command as a few guides say that's how to establish if a daemon is compiled with tcp wrappers:
https://www.cyberciti.biz/faq/tcp-wrappers-hosts-allow-deny-tutorial/ I haven't really used TCP wrappers before so I'm not even sure if my hosts.allow entries are correct: upsd : ipaddressofclientgoeshere ups : [email protected]/32 monuser@masterstaticIP monuser@slavestaticIP If yourself or anyone could please advise if this should work or if I need something different in my hosts.allow file Thank you very much once again.
