#19419 [Fbk->Opn]: Curl cannot resolve hosts

ID: 19419 User updated by: msopacua@idg.nl Reported By: msopacua@idg.nl -Status: Feedback +Status: Open -Bug Type: cURL related +Bug Type: Network related Operating System: BSD/OS 4.1 PHP Version: 4.2.3 New Comment: I've debugged this further and it seems to be a more general issue with resolver functions. gethostbyname() does the exact same thing as does Apache, when run in 'HostnameLookup' mode - they only find host in /etc/hosts and connect 'somewhere', which is not on port 53 anywhere on my system. A script: <?php print gethostbyname('bugs.php.net'); ?> with a breakpoint at dns.c:194 shows that 'hp' is NULL and h_errno is 2 (TRY_AGAIN). When the exact same code is run as a normal program, all is well, so somewhere in the php/apache combination, something goes wrong with gethostbyname and related functions, which apparently affects extension modules and apache behavior. I'll test HEAD later on.

(just give up, install Linux :) I tried with the latest CVS HEAD though. ------------------------------------------------------------------------ [2002-09-15 12:58:24] msopacua@idg.nl Curl cannot resolve hosts in php, while it can on the command line, same curl version/package.
