500 OOPS: vsftpd: refusing to run with writable root inside chroot() with vsftpd 2.3.5+

Posted on by

If you encounter this errormessage after a recent update or fresh install with vsftpd 2.3.5 or newer, here is whats happend:

As of vsftpd 2.3.5, the chroot directory that users are locked to must not be writable. This is in order to prevent a security vulnerabilty.

Depending on the configuration you utilize this can be a problem. If so I suggest for the moment to downgrade to 2.3.4 (I’m aware not the best solution!), or change your setup. People with ArchLinux have another solution to this, they can install vsftpd-ext via AUR and then set in the config allow_writable_root=YES. If someone has the patch agains the source for this, I would love to get a copy.

Downloadlinks for 2.3.4

As soon I find a better solution to this problem, I will write again.

Mounting an iOS 5.0.1 device on Ubuntu – how to fix it

After you upgraded your iOS device to 5.0.1 you probably get an error like “Unhandled Lockdown Error (-15)”. The problem is the shipped libimobiledevice which don’t like iOS 5 devices. To fix it do the following:

  • In a terminal type: “sudo apt-get install ifuse libimobiledevice-utils” (without the ” :)
  • Unlock iDevice from device’s lock screen (only needed the first time), plug it in
  • In the terminal type: “idevicepair unpair && idevicepair pair”
  • Unplug the iDevice
  • Make sure the lock screen is still unlocked
  • Plug it back in

After that it works fine, even with a locked iDevice (iPhone in my case). Most information for this article came from an article over at askubuntu.com.
