View source for SSH Key Enable/Disable

==Firewall==

To allow Roaring Penguin support staff to ssh to your remote CanIt system, you need to open up
access on your firewall such that we can get to your machine on port 22. If you do this through
the forwarding of an alternative port, please let Roaring Penguin staff know this port number
each and every time you make a new support request.

You can limit this access to our IPs. Currently we use these three IP addresses:
*72.137.191.171
*108.63.66.105
*206.248.171.190

The third is expected to be discontinued, but we will keep this wiki up to date.

Once connected to one machine, we should be able to hop from there to any other CanIt machine in
a clustered scenario, so you should not have to set up SSH to each individual node.

==Support Key==

CanIt appliances will automatically install and enable our support SSH key. If you have disabled
that key previously, or simply want to ensure that it is enabled before submitting a request, you
can do so by running the following from the command line on the CanIt machine:

    /usr/share/canit/scripts/canit-service-key --enable

When we have finished you can disable access with:

    /usr/share/canit/scripts/canit-service-key --disable

It can save a lot of time if the keys are enabled prior to a support request, so you may want to 
leave them enabled at all times. If access is limited to only our IPs, then this is 
generally safe.
