| Managing multiple hosts at the same time | ||
| </h2></div></div></div> | ||
| <p> | ||
| Cockpit allows you to access multiple hosts in a single session, | ||
| by establishing SSH connections to other hosts. This is quite | ||
| similar to logging into these other hosts using the | ||
| <span class="command"><strong>ssh</strong></span> command on the command line, with one very | ||
| important difference: | ||
| </p> | ||
| <p> | ||
| Code from the local host and all the remote hosts run at the same | ||
| time, in the same browser context. They are not isolated from | ||
| each other in the browser. All code effectively has the same | ||
| privileges as the primary session on the local host. | ||
| </p> | ||
| <p> | ||
| Thus, <span class="emphasis"><em>you should only only connect to remote hosts that | ||
| you trust</em></span>. You must be sure that none of the hosts that | ||
| you connect to will cause Cockpit to load malicious JavaScript | ||
| code into your browser. | ||
| </p> | ||
| <p> | ||
| Therefore, Cockpit will warn you before connecting to more than | ||
| one host. It is also possible to disable multiple hosts entirely, | ||
| and some operating systems do this already by default. | ||
| </p> | ||
| <p> | ||
| You can prevent loading of JavaScript, HTML, etc from more than | ||
| one host by adding this to <code class="filename">cockpit.conf</code>: | ||
| </p> | ||
| <pre class="programlisting"> | ||
| [WebService] | ||
| AllowMultiHost=false | ||
| </pre> | ||
| <p> | ||
| When you allow multiple hosts in a single Cockpit session by | ||
| setting <code class="code">AllowMultiHost</code> to true, then the user will be | ||
| warned once per session, before connecting to the second host. If | ||
| that is still too much, you can switch the warning off completely | ||
| by adding the following to <code class="filename">cockpit.conf</code>: | ||
| </p> | ||
| <pre class="programlisting"> | ||
| [Session] | ||
| WarnBeforeConnecting=false | ||
| </pre> | ||
| </div> | ||
