Hi,
I’m just migrating some stuff from my old production server to a new machine. So far everything runs nicely, and I managed to migrate a dozen WordPress sites from various domains to the new machine without too much downtime.
One domain is giving me headaches though. Here’s the updated zone file for microlinux.fr (simplified for readability):
; /var/named/zone.microlinux.fr
$TTL 86400
$ORIGIN microlinux.fr.
@ IN SOA ns.microlinux.fr. hostmaster.microlinux.fr. (
2024010606 ; sn
10800 ; refresh (3 hours)
600 ; retry (10 minutes)
1814400 ; expiry (3 weeks)
10800 ) ; minimum (3 hours)
IN NS ns.microlinux.fr.
IN NS nssec.online.net.
IN MX 10 mail.microlinux.fr.
microlinux.fr. A 51.159.21.129
ns IN A 51.159.21.129
mail IN A 51.159.21.129
@ IN TXT "v=spf1 mx ~all"
01._domainkey IN TXT ( "v=DKIM1; k=rsa; "
... ----- DKIM key 01 for microlinux.fr
_dmarc IN TXT "v=DMARC1; p=none; sp=quarantine"
cloud CNAME microlinux.fr.
docs CNAME microlinux.fr.
formation-linux CNAME microlinux.fr.
; New prod server
blog IN A 163.172.82.215
bsco IN A 163.172.82.215
compta IN A 163.172.82.215
archives IN A 163.172.82.215
www IN A 163.172.82.215
I seem to have a problem with blog.microlinux.fr.
When I do this on the DNS server itself, I get the expected result:
# host blog.microlinux.fr
blog.microlinux.fr has address 163.172.82.215
But on any other machine, I still get the old (stale) record:
# host blog.microlinux.fr
blog.microlinux.fr is an alias for microlinux.fr.
microlinux.fr has address 51.159.21.129
microlinux.fr mail is handled by 10 mail.microlinux.fr.
Of course, I did think to increment the serial number in the zone file and reloaded BIND’s configuration.
Curiously enough, all other subdomain migrations went instantly and without a hiccup. Only this one keeps stuck.
Any suggestions ?
