    <p>Another possibility: change it manually on one server. Get the encrypted password out of /etc/shadow. Now, do something like this:</p> <pre><code>for host in $HOST_LIST; do ssh $host "passwd -p 'encrypted_passwd' user" done </code></pre> <p>Of course, 'encrypted_passwd" is what you got out of /etc/shadow where you manually changed the password. And $HOST_LIST is a list of hosts where you want the password changed. That could be created simply with:</p> <pre><code>export HOST_LIST="server1 server2 server15 server67" </code></pre> <p>Or perhaps with a file (as others have suggested):</p> <pre><code>export HOST_LIST=`cat host_list.txt` </code></pre> <p>Where the file "host_list.txt" has a list of all the systems where you want the password changed.</p> <p><strong>Edit:</strong> if your version of passwd doesn't support the -p option, you might have the 'usermod' program available. The example above remains the same, simply replace 'passwd' with 'usermod'.</p> <p>Furthermore, you might consider the <a href="https://code.google.com/p/pdsh/" rel="nofollow" title="pdsh">useful tool pdsh</a>, which would simplify the above example to something like this:</p> <pre><code>echo $HOST_LIST | pdsh -Rssh -w- "usermod -p 'encrypted_passwd' user" </code></pre> <p>One last "gotcha" to look out for: the encrypted password likely contains the dollar sign character ('$') as a field separator. You'll probably have to escape those in your for loop or pdsh command (i.e. "$" becomes "\$").</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
