rorton Posted November 13, 2021 Share Posted November 13, 2021 Hi, running an Ubuntu 20.04 VM (its an appliance, provided by LibreNMS) and am struggling to get it to resolve internal IP addresses on my LAN. I have a PiHole acting as my local DNS Server - all my clients on my network point to the PiHole, and they can all resolve local addresses set-up in there, EG, if I ping the name UnRaid from a client, it resolves fine to 192.168.10.8 Now, on the Ubuntu box, this doesn't work, I can't ping anything local. I can ping stuff on the internet (ping bcc.co.uk for example) and that's perfect, its just the internal hosts. If I do an NSLOOKUP for 192.168.10.8 (the IP of the unraid box) I do get a response.. nslookup 192.168.10.8 8.10.168.192.in-addr.arpa name = UnRaid. But if I PING UnRaid from the Ubuntu box I get ping: unraid: Temporary failure in name resolution Any ideas? Im using Netplan to setup and my Netplan.yaml file is: network: version: 2 renderer: networkd ethernets: enp2s0: dhcp4: no addresses: [192.168.1.13/25] gateway4: 192.168.1.1 nameservers: addresses: [192.168.1.14] Quote Link to comment
ffgdad Posted December 31, 2021 Share Posted December 31, 2021 im having a similar problem. I dont know if its at all the same though. I as of last night added a ubuntu VM. and now I dont have access to the web UI. I tried localhost:23 and that didnt work. Im about to call comcast for my router password. (I should write that down.) I thought I would come here first to see if anyone else had this problem. I have had acess to the web login up until I installed ubuntu. Quote Link to comment
ffgdad Posted December 31, 2021 Share Posted December 31, 2021 My thing has been taken care of. I had to log into my comcast router and change my server settings from DHCP to Reserved. Then I gave it a static IP. I dont know if it was a ubuntu thing or if it was the modem. This took care of my problem. 1 Quote Link to comment
