NOTE TO SELF: change DNS on TransIP VPS machines. Today I got an email from TransIP. Nameservers are changed. Please update your virtual machine. Old info : 80.69.67.66, 80.69.67.67, 2a01:7c8:a::c53, 2a01:7c8:b::c53 New info is : 195.8.195.8 195.135.195.135 2a01:7c8:7000:195::8:195:8 2a01:7c8:7000:195::135:195:135 Ok, now I have to get into my machine and update this stuff. I used my normal SSH login to get a prompt. (user oetelx can use sudo because this user is in admin group ) I checked if the new IP adresses actually are running a valid DNS server before assuming anything. oetelx@www:~$ dig @195.135.195.135 www.oetelaar.com ; <<>> DiG 9.11.3-1ubuntu1.13-Ubuntu <<>> @195.135.195.135 www.oetelaar.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 3218 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 2, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 1280 ;
