I installed Linux Mint on a system, then later I changed the hostname to cw. But nslookup reports both names. I tried
/etc/init.d/dhcp stop then start, I tried
/etc/init.d/network restart but no luck. Is there a way to flush this record ? thank you.
18.104.22.168.in-addr.arpa name = cw.lan.
22.214.171.124.in-addr.arpa name = mint.lan.
Yes, you can restart unbound. If this happens again, this is a bug.
Thank you. Restarted unbound and it cleared the PTR record.
This happens often in my network, I bring in a laptop, do an install, change hostname, reboot laptop and then nslookup reports 2 PTR records. If I change the hostname again, 3 PTR records.
Could you report this on Bugzilla, please?
