Public bug reported:
After upgrading the house server to 12.04 vsftpd no longer accepts
uploads to / in a chroot account.
This is needed because the Brother Multi Function Printer has a scan to
ftp function (which rocks, just scan and forget about the documents)
which uploads such file names as this:
Fri Jun 1 13:03:28 2012 [pid 3] [mfpscan] FAIL UPLOAD: Client
"192.168.1.8", "/scan__000227.pdf", 0.00Kbyte/sec
There is no newer firmware and I can't seem to persuade it to not
specify / in the filename.
When loging into the server this message is produced:
OOPS: vsftpd: refusing to run with writable root inside chroot()
OOPS: priv_sock_get_cmd
Googeling this there seems to be multiple patches to work around the
problem (resulting in the "allow_writeable_root" in the submitted
vsftpd.conf), but none of them are applied on 12.04 it seems. strings on
the binary does not give me any hope that any other configuration
directive has been added for this.
I understand the reason for the security patch that produces this
problem, but it seems quite acceptable since there is anonymous login
and the ftp server is not reachable from the internet. This would be
the case for most people using vsftpd for this purpose.
