There are two categories of MOTDs: the cluster-level MOTD and the data Vserver-level MOTD. A user logging in to a data Vserver’s clustershell will potentially see two messages: the cluster-level MOTD followed by the Vserver-level MOTD for that Vserver. The cluster administrator can enable or disable the cluster-level MOTD on a per-Vserver basis. If the cluster administrator disables the cluster-level MOTD for a Vserver, a user logging into the Vserver will not see the cluster-level message. Only a cluster administrator can enable or disable the cluster-level message.

Parameters

-vserver <Vserver Name> - Vserver Name

Use this parameter to specify the Vserver whose MOTD will be modified. Use the name of the cluster admin Vserver to modify the cluster-level message.

{ [-message <text>] - Message of the Day (MOTD)

This optional parameter can be used to specify a message. If you use this parameter, the MOTD cannot contain newlines (also known as end of lines (EOLs) or line breaks). If you do not specify any parameter other than the -vserver parameter, you will be prompted to enter the message interactively. Messages entered interactively can contain newlines. Non-ASCII characters must be provided as Unicode UTF-8.

The message may contain dynamically generated content using the following escape sequences:

\\ - A single backlash character.
\b - No output: supported for compatibility with Linux only.
\C - Cluster name.
\d - Current date as set on the login node.
\t - Current time as set on the login node.
\I - Incoming LIF IP address (prints 'console' for a console login).
\l - Login device name (prints 'console' for a console login).
\L - Last login for the user on any node in the cluster.
\m - Machine architecture.
\n - Node or data Vserver name.
\N - Name of user logging in.
\o - Same as \O. Provided for Linux compatibility.
\O - DNS domain name of the node. Note that the output is dependent on the network configuration and may be empty.
\r - Software release number.
\s - Operating system name.
\u - Number of active clustershell sessions on the local node. For the cluster admin: all clustershell users. For the data Vserver admin: only active sessions for that data Vserver.
\U - Same as \u, but has 'user' or 'users' appended.
\v - Effective cluster version string.
\W - Active sessions across the cluster for the user logging in ('who').

A backslash followed by any other character is emitted as entered.

| [-uri {scheme://(hostname|IPv4 Address|'['IPv6 Address']')…}] - Download URI for the MOTD }

Use this parameter to specify the URI from where the message of the day will be downloaded. Note that the message must not exceed 2048 bytes in length. Non-ASCII characters must be provided as Unicode UTF-8.

[-is-cluster-message-enabled {true|false}] - Is Cluster-level Message Enabled?

Use this parameter to enable or disable the display of the cluster-level MOTD for the specified Vserver.

Examples

This example shows how to enter a MOTD interactively:

cluster1::> security login motd modify -vserver vs0

Enter the message of the day for Vserver "vs0".
Max size: 2048. Enter a blank line to terminate input. Press Ctrl-C to abort.
