Red Hat Bugzilla – Bug 19485
"host" utility shows incorrect results when searching multiple domains
Last modified: 2007-04-18 12:29:25 EDT
Red Hat 7.0 system, configured as a slave nameserver for 3 domains. Those three domains are listed in the 'search' directive within /etc/resolv.conf: search abc.com xyz.com foo.net The 'host' utility in bind-utils-8.2.2_P5-25 doesn't work properly for lookups within the second and third domains. Typing "host server-name", where "server-name" exists in the second or third zone, will not display the address of the host. But it will display other zone info, such as "mail is handled (pri-nn) by". If you type "host -v server-name" then the A record DOES appear in the output. If you change the order of the domains in the resolv.conf 'search' directive such that "server-name"'s domain is listed first, then "host server-name" displays the expected result: server-name.xyz.com has address 192.168.1.38 I have a Red Hat 6.1 server that is also a slave nameserver for the same three domains. It is configured the same as the 7.0 server as far as named is concerned. /etc/resolv.conf and /etc/named.conf are identical. On the 6.1 server, 'host' is from bind-utils-8.2.2_P3-1. This version works as expected.
The host command is in the bind-utils package. Reassigning to the "bind" component.
The bind-8.2.2_P7-0.6.2 package was released for Red Hat 6.x to fix a DoS attack (see RHSA-2000:107-01). This updated package introduces this same bug into Red Hat 6.x - the resolver search list is broken.
Fixed in 7.1
