Easy ssh configuration with .ssh/config file

2011-04-11 1 min read Bash Learning Linux

If you ssh to many hosts then you are aware of the pain that it takes to ssh with different username and hostname. There is an alias that you can creat with native ssh though. Here I will show you the same with an example.

  <td>
    <div class="text codecolorer">
      cat <<EOF >>~/.ssh/config<br /> Host <alias><br /> Username <user name><br /> Port <port number><br /> Hostname <hostname>
    </div>
  </td>
</tr>

You can optionally omit the parameters that you do not require explicitly. For example, if your port number is default then you can simply ignore the parameter.

I was using the pkg-get util from the freesunware.com

The utility was using wget and it was failing constantly. From the looks of it, it was very clear that the wget utility was unable to find the <a class="zem_slink" title="IP address" rel="wikipedia" href="http://en.wikipedia.org/wiki/IP_address">IP address from the name. <a class="zem_slink" title="Name resolution" rel="wikipedia" href="http://en.wikipedia.org/wiki/Name_resolution">Name resolution was not happening, while dig and <a class="zem_slink" title="Nslookup" rel="wikipedia" href="http://en.wikipedia.org/wiki/Nslookup">nslookup was able to do the DNS lookup.

If you have your domain in the Dynamic DNS located at : <a href="http://freedns.afraid.org">Freedns then you know how difficult it is to get the Dynamic DNS client to work with Fedora. Not that it does not work, but you need to configure it properly and there are lot of parameters. But not any more. Now you can install the afraid Dynamic DNS client and just put your Account Hash in the config file and you are ready with the setup to update the DNS entry whenever your IP changes. So lets get started:
