dos2unix on a file upload

[david]

Hi there,

Does anybody know of some restriction that stops the apache user on
doing a dos2unix on a file upload from php? I'm getting 'permission
denied' on some temp file that it tries to create.

I tried doing it from the command line by manually placing a fake
upload file in /tmp:

[dave@willow dave]$ ls -ltr /tmp
-rw------- 1 apache apache 307 Mar 10 11:32 phpjmyaQR
[dave@willow dave]$ sudo -u apache dos2unix /tmp/phpjmyaQR
dos2unix: converting file /tmp/phpjmyaQR to UNIX format ...
Failed to open output temp file: Permission denied
dos2unix: problems converting file /tmp/phpjmyaQR

However if I change the owner and group to me, it will work fine:

[dave@willow dave]$ ls -l /tmp
-rw------- 1 dave dave 307 Mar 10 14:53 phpjmyaQR
[dave@willow dave]$ sudo -u dave dos2unix /tmp/phpjmyaQR
dos2unix: converting file /tmp/phpdave to UNIX format ...
[dave@willow dave]$
Red Hat Linux 3.2.2-5
Apache 2.0.40

Ta,
Dave

Correct me if I am wrong but the following
[dave@willow dave]$ ls -ltr /tmp
-rw------- 1 apache apache 307 Mar 10 11:32 phpjmyaQR

tells me that you are logged in as user dave true?

And the file phpjyaQR has read/write permissions for owner/group
apache/apache only - nobody else.

Thus - since only user/group apache/apache has access to the file, this
would explain when you are user dave as to why you get a 'Failed to
open' and permission denied message.

If you have access to user 'apache' then su to it and try and perform
your dos2unix command and it should work from there.

In addition, check the syntax for the command as I *think* you should be
executing

$ dos2unix originalFile > convertedFilename
