Re: [Nut-upsuser] Can't get NUT slave to connect to master

Hi thanks for all the help with this. I may have now resolved this and got things working... All I've ended up doing is making the slave the master and the master the slave! They now connect! What is strange though is that one machine is Ubuntu and one is Debian - with Debian as the Master

Re: [Nut-upsuser] Can't get NUT slave to connect to master

Try ALL:ALL in /etc/hosts.allow temporarily. If that still doesn't work, it's likely something else. If it does, only then screw with creating narrow rules . . . - Tim On November 25, 2016 6:37:02 AM CST, Roger Price wrote: >On Fri, 25 Nov 2016, Jonah Naylor wrote: > >>

Re: [Nut-upsuser] Can't get NUT slave to connect to master

Hi, When on the same LAN it just worked without anything in the hosts.allow file. It's difficult for me to now put the slave back on the same lan as the master due to the way the production servers are being used... Causing downtime etc... I do have another spare server though which I could put

Hi thanks Roger, I've amended my hosts.allow file to your suggested one - thanks for that. I'm still getting "Connection refused on the client cgi screen as well as in the shell it gives me UPS upsname@ipaddresshere is unavailable... Any ideas what I can try next to debug why it's not working.

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

Hi thanks for helping. I don't think nut is built with TCP wrappers support, although the package is listed as depending on libwrap... I ran this command: ldd /sbin/upsd | grep libwrap.so and it has returned no output. Does this mean I have to compile from source or is there a way to add the

Hi thanks for the reply. The servers can ping each other... The router log doesn't show anything and I am the admin for the servers. The machines firewalls allow each other's ips etc. Part of the issue is possibly that I just don't know if I've set up NUT correctly for this arrangement? Like I

Hi can anyone please help. Although I have two servers in the same cabinet/room and sharing the same UPS - they're on different networks. I've tried everything I can find online, but whatever I do I can't get the slave nut client to connect to the master. When testing then on the same LAN, they
