[jira] Created: (TS-597) when using SplitDNS, the common dns
setting is not honored
when using SplitDNS, the common dns setting is not honored
----------------------------------------------------------
Key: TS-597
URL: https://issues.apache.org/jira/browse/TS-597
Project: Traffic Server
Issue Type: Sub-task
Components: DNS
Affects Versions: 2.1.4
Reporter: Zhao Yongming
When using the trunk codes, and setup a splitdns.config without wild cast rule:
dest_domain=yahoo.com named="68.180.131.16"
dest_domain=inktomi.com named="68.180.131.16"
dest_domain=google.com named="8.8.8.8"
and records:
CONFIG proxy.config.http.no_dns_just_forward_to_parent INT 0
CONFIG proxy.config.dns.search_default_domains INT 1
CONFIG proxy.config.dns.splitDNS.enabled INT 1
CONFIG proxy.config.dns.max_dns_in_flight INT 2048
CONFIG proxy.config.dns.url_expansions STRING NULL
CONFIG proxy.config.dns.round_robin_nameservers INT 0
CONFIG proxy.config.dns.nameservers STRING 202.106.0.20
CONFIG proxy.config.dns.resolv_conf STRING NULL
CONFIG proxy.config.dns.validate_query_name INT 0
CONFIG proxy.config.diags.debug.tags STRING split.*|dns.*|hostdb.*
splitdns will just make the default dns server as 127.0.0.1 regards of the setting from /etc/resolv.conf etc

[jira] Updated: (TS-597) when using SplitDNS, the common dns
setting is not honored
Posted by "Zhao Yongming (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-597?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zhao Yongming updated TS-597:
-----------------------------
Attachment: TS-597.patch
I have removed the codes in SplitDNS which take care of the default server, and now, SplitDNS just work when a hostname match in rule, and leave other request to default dns processor.
this patch also removed the default domain config, as it should not be used.
the change passed regression test on trunk.
here is the debug log after change:
