[thelist] User permissions, ftp and apache/php

[Simon Wheatley (lists)]

Hello

I'm wrestling with a new Linux webserver setup. The problem seems to be 
that file permissions reset whenever I upload a new file to the site. I 
have recursively chmod'd the files to 755, when they work fine, but as soon 
as I edit one and re-upload they lose their permissions become 
"rw-r-----"??

I'm a newbie with Linux, how can I prevent this from happening?

TIA

Simon
