Dealing with unexpected RCODE (SERVFAIL)
Hello list, In my logs I see numerous line like these: Mar 16 04:59:13 mx02 named[4606]: unexpected RCODE (SERVFAIL) resolving 'hotmeil.com/MX/IN': 10.2.1.3#53 Mar 16 04:59:14 mx02 named[4606]: unexpected RCODE (SERVFAIL) resolving 'hotmeil.com/MX/IN': 10.0.1.3#53 Mar 16 04:59:15 mx02 named[4606]: unexpected RCODE (SERVFAIL) resolving 'hotmeil.com/MX/IN': 10.1.1.3#53 The hostname that's being tried to resolve obviously has a typo in it, users tend to make such mistakes a lot. In our case mx02 runs it own caching nameserver, which uses our internal caching nameservers (10,[012].1.3) as forwarders. Is there something I can change in the configuration of either (or both) mx02 or 10.[012].1.3 to prevent the unexpected? Is it safe to ignore these error completely (either in our filters or in bind's configuration)? I'm a bit hesitant to do so, since I got the feeling that I might miss out on actual problems occuring (other than users not being able to spell). I google'd around several times, but could never find any useful information on this subject. -- Regards, Ruben Laban Senior Systems and Network Administrator ISM eCompany ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

Re: How to Create a MX record for a subdomain.

Such as : smtpMX 10.0.106.1 but this occurs an error: dns_rdata_fromtext: /var/named/named.domain.com:18: near '10.0.106.1': not a valid number You missed the preference number, and a MX record should point to an A record, not an IP. E.g.: smtpMX 10 mail.example.net. -- Regards, Ruben Laban Systems and Network Administrator ISM eCompany ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
