31.14. Very Secure ftpd

vsftpd can provide access to installation trees for para-virtualized guests (for example, the Red
Hat Enterprise Linux 5 repositories) or other data. If you have not installed vsftpd during the server
installation you can grab the RPM package from your Server directory of your installation media and
install it using the rpm -ivh vsftpd*.rpm (note that the RPM package must be in your current
directory).
1. To configure vsftpd, edit /etc/passwd using vipw and change the ftp user's home directory to
the directory where you are going to keep the installation trees for your para-virtualized guests. An
example entry for the FTP user would look like the following:
ftp:x:14:50:FTP User:/xen/pub:/sbin/nologin
2. Verify that vsftpd is not enabled using the chkconfig --list vsftpd:
$ chkconfig ---list vsftpd
vsftpd 0:off
3. Run the chkconfig --levels 345 vsftpd on to start vsftpd automatically for run levels 3, 4
and 5.
4. Use the chkconfig --list vsftpd command to verify the vsftpd daemon is enabled to
start during system boot:
$ chkconfig ---list vsftpd
vsftpd 0:off
5. use the service vsftpd start vsftpd to start the vsftpd service:
$service vsftpd start vsftpd
Starting vsftpd for vsftpd:

31.15. Configuring LUN Persistence

This section covers how to implement
without multipath.
Implementing LUN persistence without multipath
If your system is not using multipath, you can use udev to implement LUN persistence. Before
implementing LUN persistence in your system, ensure that you acquire the proper UUIDs. Once you
acquire these, you can configure LUN persistence by editing the scsi_id file that resides in the /etc
directory. Once you have this file open in a text editor, you must comment out this line:
1:off 2:off 3:off
1:off 2:off 3:on
LUN
persistence in guests and on the host machine with and
4:off 5:off 6:off
4:on 5:on 6:off
