FTP in PHP generating failed to open stream: Permission denied

I have a working script on an existing web server Linux (FC7) that I'm now moving to a brand new sever just installed with FC10 and Apache.

The script attempts an FTP connect to copy files locally but is failing with a "failed to open stream: Permission denied".

All the directories have 777 permissions. Safe_mode is off via PHP_info. Since this a brand new install, I'm assuming something is set by default that I have to change (I've had to change a couple of things with setsebool so far to allow remote MySQL connections, etc, so maybe there's another switch affecting FTP that I'm unaware of.)

I can't find any problem with the code.  Have you tried doing the FTP transfer manually?  Can you try it as the httpd/php user?

If I ssh in as the cer user (the owner of the folder I'm trying to use), I can ftp to the machine and grab the file. I'm not sure I know how to start an ftp session as the apache or php user.

Well, If you have root access, you can `su <apache user>` (will likely need root password) and then try the same ftp command.  Apache (httpd) on linux often runs as `nobody` or `www`.  The username should be set in httpd.conf.

I'm sorry, this is a bit of trial an error.  Maybe someone else will have a more inspired idea.

One of our local tech guys pointed out the problem. Actually it turns out that it's the new SElinux security addons that are new in FC10 that were causing the problem. I just disabled that and it all works now.
