Did you know that if you press “~” then C while in an ssh session, you get access to several useful commands? You can set up new local and remote forwarding, or stop existing forwarding, all while the connection is still running. From inside the session. But one little-known fact is that you can also run arbitrary local commands too.
The Problem: You need to access a remote system with
rsync to back it up. But some of the files or directories you need to back up need root permissions to read. You need to automate the backups, so you can’t use a password or passphrase. But you really don’t want to allow passwordless logins to the remote, and especially not as root! So what to do?

Someone asked on the Ubuntu users mailing list how they could set up a keypress that would resize the currently active window to 75% of its present width. It took a little thought, but eventually the tools were found…

The full story is here, but this blog entry is about how I added the necessary default route. You wouldn’t think that would be a big deaI, but it turns out that adding specifically a default route to one of these units is surprisingly tricky. Continue reading

In the end an alternative was found, but just for the exercise, our team at the camp used my new hotspot, and it worked really well.
After much time thinking about it, I have kicked off a new business venture – Into6. The new venture specialises in IPv6 – training, analysis, consultancy, technical support, you name it. If you are interested in IPv6, do check out the Into6 website, because that is where I will be doing all my future blogging about IPv6. Over time I will move or copy the IPv6-related blog entries from this site to the Into6 site, too.
As part of starting up Into6, I’ve also set up a Twitter account
