Fedora 9: Selinux policy is preventing the ftp deamon from writing to apublic directory

I am trying to upload a file from Windows Vista smart to my fedora server and my server is giving me the message:

SElinux AVC denial:
 Selinux policy is preventing the ftp deamon from writing to a public directory

the I am given more detailed description:

" Summary:

SELinux policy is preventing the ftp daemon from writing to a public directory.

Detailed Description:

SELinux policy is preventing the ftp daemon from writing to a public directory.
If ftpd is not setup to allow anonymous writes, this could signal a intrusion
attempt.

Allowing Access:

If the ftp daemon should be allowed to write to this directory you need to turn
on the allow_ftpd_anon_write boolean and change the file context of the public
directory to public_content_rw_t. Read the ftpd_selinux man page for further
information: "setsebool -P allow_ftpd_anon_write=1; chcon -t public_content_rw_t
"

Fix Command:

setsebool -P allow_ftpd_anon_write=1

Run it from the commandline on your Fedora server as Root-user:

setsebool -P allow_ftpd_anon_write=1



setsebool(8)          SELinux Command Line documentation          setsebool(8)

NAME
       setsebool - set SELinux boolean value

SYNOPSIS
       setsebool [ -P ] boolean value | bool1=val1 bool2=val2 ...

DESCRIPTION
       setsebool  sets the current state of a particular SELinux boolean or a list of booleans to a
       given value. The value may be 1 or true or on to enable the boolean, or 0 or false or off to
       disable it.

       Without  the  -P  option,  only the current boolean value is affected; the boot-time default
       settings are not changed.

       If the -P option is given, all pending values are written to the policy  file  on  disk.  So
       they will be persistant across reboots.

Be certain this is what you want to do. From a security standpoint, anonymous FTP access is usually limited to read only; write acces requires an authenticated user, both to control access to resources on your server, and to provide an audit trail for the access. Hence the standard FTP policy.

If you decide to do authenticated access, there are plenty of ways create an environment where both the Linux systems and the Windows Vista share a single user space (one set of accounts for all systems) so that you don't have to worry about managing separate accounts on different platforms.
