    <title>Transition Technology: Ticket #673: Install mosh - the mobile shell</title>
    <link>http://localhost:8080/trac/ticket/673</link>
    <description>&lt;p&gt;
The mobile shell enables terminal connections to stay up when using really bad connections, for example on a train, see:
&lt;/p&gt;

          &lt;ul&gt;
            &lt;li&gt;&lt;strong&gt;hours&lt;/strong&gt;
                changed from &lt;em&gt;0.0&lt;/em&gt; to &lt;em&gt;0.25&lt;/em&gt;
            &lt;/li&gt;
            &lt;li&gt;&lt;strong&gt;totalhours&lt;/strong&gt;
                changed from &lt;em&gt;0.0&lt;/em&gt; to &lt;em&gt;0.25&lt;/em&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;p&gt;
Mosh was installed a while ago on the servers and this was documented in the &lt;tt&gt;/root/Changelog&lt;/tt&gt; but not on a ticket or the wiki (sorry):
&lt;/p&gt;
&lt;p&gt;
Install on &lt;a class="wiki" href="http://localhost:8080/trac/wiki/ParrotServer"&gt;wiki:ParrotServer&lt;/a&gt;:
&lt;/p&gt;
&lt;pre class="wiki"&gt;2014-01-03      chris
        *       mosh : installed
&lt;/pre&gt;&lt;p&gt;
Install on &lt;a class="wiki" href="http://localhost:8080/trac/wiki/PenguinServer"&gt;wiki:PenguinServer&lt;/a&gt;:
&lt;/p&gt;
&lt;pre class="wiki"&gt;2013-12-26      chris
        *       mosh : installed
&lt;/pre&gt;&lt;p&gt;
Install on &lt;a class="wiki" href="http://localhost:8080/trac/wiki/PuffinServer"&gt;wiki:PuffinServer&lt;/a&gt;:
&lt;/p&gt;
&lt;pre class="wiki"&gt;2014-01-10      chris
        *       mosh : installed
&lt;/pre&gt;&lt;p&gt;
However it doesn't currently work on &lt;a class="wiki" href="http://localhost:8080/trac/wiki/PuffinServer"&gt;wiki:PuffinServer&lt;/a&gt; as the CSF firewall blocks it. The changes needed to enable mosh to work have been made to the &lt;tt&gt;/etc/csf/csf.conf&lt;/tt&gt; script:
&lt;/p&gt;
&lt;pre class="wiki"&gt;# Allow incoming UDP ports
UDP_IN = "20,21,53,123,161,33434:33523,60000:60040"
# Allow outgoing UDP ports
# To allow outgoing traceroute add 33434:33523 to this list
UDP_OUT = "20,21,53,113,123,161,33434:33523,60000:60040"
&lt;/pre&gt;&lt;p&gt;
UDP ports 60000 to 60040 have been opened here, however the updated csf config hasn't yet been applied as it takes quite a long time to reload the firewall config.
&lt;/p&gt;

          &lt;ul&gt;
            &lt;li&gt;&lt;strong&gt;hours&lt;/strong&gt;
                changed from &lt;em&gt;0.0&lt;/em&gt; to &lt;em&gt;0.2&lt;/em&gt;
            &lt;/li&gt;
            &lt;li&gt;&lt;strong&gt;status&lt;/strong&gt;
                changed from &lt;em&gt;new&lt;/em&gt; to &lt;em&gt;closed&lt;/em&gt;
            &lt;/li&gt;
            &lt;li&gt;&lt;strong&gt;resolution&lt;/strong&gt;
                set to &lt;em&gt;fixed&lt;/em&gt;
            &lt;/li&gt;
            &lt;li&gt;&lt;strong&gt;totalhours&lt;/strong&gt;
                changed from &lt;em&gt;0.25&lt;/em&gt; to &lt;em&gt;0.45&lt;/em&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;p&gt;
Replying to &lt;a href="http://localhost:8080/trac/ticket/673#comment:1" title="Comment 1 for Ticket #673"&gt;chris&lt;/a&gt;:
&lt;/p&gt;

&lt;p&gt;
UDP ports 60000 to 60040 have been opened here, however the updated csf config hasn't yet been applied as it takes quite a long time to reload the firewall config.
&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;
The &lt;a class="wiki" href="http://localhost:8080/trac/wiki/PuffinServer"&gt;wiki:PuffinServer&lt;/a&gt; reboot resulted in the firewall being reloaded and now mosh works.
&lt;/p&gt;
&lt;p&gt;
The documentation has been updated for all three servers:
&lt;/p&gt;

&lt;/li&gt;&lt;li&gt;&lt;a class="wiki" href="http://localhost:8080/trac/wiki/PenguinServer#ConsoleandSSHAccess"&gt;wiki:PenguinServer#ConsoleandSSHAccess&lt;/a&gt;
&lt;/li&gt;&lt;li&gt;&lt;a class="wiki" href="http://localhost:8080/trac/wiki/ParrotServer#ConsoleandSSHAccess"&gt;wiki:ParrotServer#ConsoleandSSHAccess&lt;/a&gt;
&lt;/li&gt;&lt;/ul&gt;
