#14897 [Opn->Fbk]: "unable to fork" - cause & solution (well, at least for me)

ID: 14897 Updated by: iliaa@php.net Reported By: louis@steelbytes.com -Status: Open +Status: Feedback Bug Type: Program Execution Operating System: Windows 2000 PHP Version: 4.1.1 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip Previous Comments: ------------------------------------------------------------------------ [2002-01-21 07:16:43] louis@steelbytes.com re enable access to cmd.exe for php: if you are using IIS, then PHP will be run using the IWAM_<machinename> account. so you would have to set the right for cmd.exe to include this account. if you are using a different web server, then I have no idea what account would need access to cmd.exe re stopping php from prepending "cmd /c ": not that I know of, and hence the bug report that I posted requesting the developers changing it. ------------------------------------------------------------------------ [2002-01-21 06:32:42] davidfelton@codemasters.com Is there a way to enable access to cmd.exe so that it is only available to php.exe? Or a way of stopping php prepending "cmd.exe /c " in front of any calls to exec? thanks. ------------------------------------------------------------------------ [2002-01-17 19:40:26] louis@steelbytes.com this is a suggestion to the developers to do, because the only way for a script writer to solve this is to enabled access to cmd.exe which many would perfer to not have to do. ------------------------------------------------------------------------ [2002-01-17 05:56:27] davidfelton@codemasters.com clarification: is this a suggestion of a way to fix the problem myself (so I can call programs), or a suggestion to the developers? ------------------------------------------------------------------------ [2002-01-06 22:00:12] louis@steelbytes.com in 4.0.6, popen() would just call CreateProcess() with the specified command. this was ok. in 4.1.0 popen() now prepends "cmd.exe /c " (or "command.com /c " on win9x). the problem with this, is that many web admins will disable access for the web apps to access cmd.exe (eg, MS's IISLockDown does this), and hence even though the web app may have access to c:\utils\myapp.exe, a command like exec("c:\utils\myapp.exe") now fails on 4.1.0 but works on on 4.0.6. also, the hardcoding of cmd.exe should not be done. it should get it from the enviroment. summary: have commands that prepend the result of an enviroment lookup on "%comspec% /c " to the front of a command AND have commands that dont, so that I can call exec("c:\utils\myapp.exe"); without having to enable access to cmd.exe OR any interpretation of these issues, that allow for a sensible amount of flexibilty.
