#18966 [Com]: gethostbyaddr() crashes Apache on certain IPs

ID: 18966 Comment by: msopacua@idg.nl Reported By: php@silisoftware.com Status: Bogus Bug Type: Reproducible crash Operating System: Windows XP Home (NT5.1b2600) PHP Version: 4.2.2 New Comment: This does have a very suspicious nameserver: For authoritative answers, see: mitsui.com 3600 IN SOA nyc0x001.mitsui.com amonty.nyc.mitsui.com( 130 ;serial (version) 3600 ;refresh period 600 ;retry refresh this often 86400 ;expiration period 3600 ;minimum TTL ) nyc0x001 But indeed - if Webalizer freaks out, the bug is probably in XP. You may have stumbled upon something really nice here.

I run your script on a Windows 2000 machine and it worked just fine. It simply printed '208.133.226.85'. ------------------------------------------------------------------------ [2002-08-19 11:07:07] php@silisoftware.com gethostbyaddr() crashes Apache (v1.3.24) when looking up certain IPs. Example script: echo gethostbyaddr('208.133.226.85'); Every other IP I've tried (so far about 40,000) didn't have any problems. I tried the above line on another server running PHP4.2.2, Apache v1.3.26 and some form of Linux (2.4.9-31) and that had no problems. Probably related: the Windows port of Webalizer crashes when performing DNS lookups on the same line of the log file, so I suspect it's something to do with DNS lookups in Windows (?). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18966&edit=1
