Moving or Reusing a Shared Directory
If you rename an NFS-mounted directory, NFS clients must unmount and remount the
imported directory before they can see the new contents.
For example, if a server is sharing /opt/myapp, and you move /opt/myapp to /opt/
myapp.old then rebuild and repopulate /opt/myapp, all the NFS clients must unmount
and remount the directory, for example (as superuser on each client):
# umount /opt/myapp
# mount -a
Any client on which this is not done will continue to see the former contents of /opt/
myapp, that is /opt/myapp.old.
You can encounter the same problem in a slightly different way when you reuse an
LVM volume.
For example, suppose you unmount an obsolete file system named /projects from
a file server named fp_server, and subsequently reuse the logical volume, mounting
a file system /newprojects on it.
Any client that fails to unmount /projects will see the contents of fp_server:/
newprojects, labeled /projects.
Configuring File Transfer Protocol (FTP)
File Transfer Protocol (FTP) is a mechanism for copying files from one system to another.
These sections provide configuration procedures and troubleshooting information.
IMPORTANT: With FTP and other Internet Services protocols (such as rlogin, rsh, and
rcp) information (including passwords) is passed between two systems in clear text
and is not encrypted. Use Internet Services only between hosts that are well-known
and defined to each other and within a private internal network behind a firewall.
When communicating over an untrusted network, secure the communications using
IPSec or Kerberos. For more information regarding Internet security with HP-UX, see
HP-UX System Administrator's Guide:Security Management.
A secure alternative to FTP is sftp (Secure File Transfer Protocol), which is provided
as part of the secure shell, ssh. For information about these alternatives, see HP-UX
System Administrator's Guide:Security Management and the manpages sftp(1) and ssh(1).
Configuring Anonymous FTP
Anonymous FTP allows users who do not have an account on a given system to send
files to, and retrieve them from, that system.
