I have 777 and hesk user for attachments directory, but I recieve attaches with rights "nobody", and I can't download it.. Only when I make 777 again and set group and permissions recursively I can get them. How can I solve it?

This all boils down to how your server is setup. Your PHP probably runs under user "Nobody" hence all the files it generates are under user "Nobody".
To fix the issue your server would need to be configured to run PHP under your account username (for example using SuPHP).

Wait, you mean you can't download files when you click from within the "View ticket" page, or when you try downloading directly over FTP?
Do you have email piping/pop3 fetching enabled?

Then this is definitely permissions problem because the PHP pipe is running under a different user.
You can try setting chmod and see if that helps:
1. open file inc/attachments.inc.php
2. inside find
3. just ABOVE that add
Code: Select all
@chmod(dirname(dirname(__FILE__)).'/'.$hesk_settings['attach_dir'].'/'.$file_name, 0644);
3. save, upload and test to see if it works on new tickets
Not sure if your host allows it, but you could also try to change the owner instead in step 2 above:
Code: Select all
@chown(dirname(dirname(__FILE__)).'/'.$hesk_settings['attach_dir'].'/'.$file_name, USER);
(replace USER with the username PHP runs under, either as "username" or numerical value (again check with your host to confirm under what user your scripts execute via browser, not pipe).

Thank you!
The problem was that MTA Postfix making pipe commands from "nobody" by default. I made in default_privs real user and it works correct now.
Another problem that all files still have 0600. This is not a big problem, but
@chmod(dirname(dirname(__FILE__)).'/'.$hesk_settings['attach_dir'].'/'.$file_name, 0644);
this did not solve the problem((

If the chmod doesn't work then it's either disabled in PHP or user running PHP doesn't have permissions to modify it?

I made a test file with this code:
Code: Select all
$text = "Test text";
$fp = fopen("file.txt", "w");
fwrite($fp, $text);
fclose($fp);
I got file created with 0644
I don't know why
Code: Select all
@chmod(dirname(dirname(__FILE__)).'/'.$hesk_settings['attach_dir'].'/'.$file_name, 0644);
not working

Because on your server piped script is running under a different username than the script you open via browser.
