Bug #27163 [Com]: gethostbyname() returns server IP for non-existent hosts

Edit report at https://bugs.php.net/bug.php?id=27163&edit=1 ID: 27163 Comment by: s at finalclass dot net Reported by: turtle at rawx dot net Summary: gethostbyname() returns server IP for non-existent hosts Status: Not a bug Type: Bug Package: Network related Operating System: Linux 2.4.24 PHP Version: 4.3.5RC2 Block user comment: N Private report: N New Comment: Try removing this line: domain YOUR_DOMAIN_NAMe from /etc/resolve.conf file. In my case this solved the problem. Previous Comments: ------------------------------------------------------------------------ [2004-02-05 21:26:00] iliaa@php.net It works fine here, when it fails to resolve the original domain string is returned. If you get anything else it could be due to named issues on your system. ------------------------------------------------------------------------ [2004-02-05 15:13:09] turtle at rawx dot net Description: ------------ gethostbyname() is returning my own IP address for non-existent domain names. The expected behavior is that it will return the original name back to you. Resolving a real domain returns it's correct IP address. This issue affects other DNS resoluton commands too... for example, checkdnsrr('totallyfake456jh47r.com','A') returns TRUE. Using local resolution commands, the expected result (NXDOMAIN) is returned: /:~# host totallyfake456jh47r.com Host totallyfake456jh47r.com not found: 3(NXDOMAIN) This may similar (same?) as bug ID <a href='http://bugs.php.net/bug.php?id=21487&edit=2'>21487</a>. PHP configuration: ./configure --with-apxs2=/www/bin/apxs --with-config-file-path=/etc --with-mcrypt --enable-ftp --with-gd=/usr/local --with-zlib-dir=/usr/local --with-jpeg-dir=/usr/local --with-png-dir=/usr/local --with-mysql --with-xml --enable-track-vars Reproduce code: --------------- echo gethostbyname('totallyfake456jh47r.com'); Expected result: ---------------- totallyfake456jh47r.com Actual result: -------------- 66.166.160.74 (my server's own IP) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=27163&edit=1
