Update:  this was hacky and clumsy, see the more recent SSH on Port 995 for something better.

I’ll leave this up, though, rather than attempt to whitewash my mistake.

So, I’m piddling around, cleaning up old kernels on my crappy Ubuntu server.  I thought I’d make a note for future reference, I always have to Google whenever it occurs to me to do this.

Find the running kernel (so I know what not to delete):

root@schoolserver:~# uname -r
3.19.0-47-generic

Here’s what I’ve got installed:

root@schoolserver:~# dpkg --list | grep linux-image | grep -v module
ii  linux-image-3.19.0-43-generic        3.19.0-43.49~14.04.1                 i386         Linux kernel image for version 3.19.0 on 32 bit x86 SMP
ii  linux-image-3.19.0-47-generic        3.19.0-47.53~14.04.1                 i386         Linux kernel image for version 3.19.0 on 32 bit x86 SMP
ii  linux-image-generic-lts-vivid        3.19.0.47.32                         i386         Generic Linux kernel image

Lemme remove the old, unused one:

root@schoolserver:~# apt-get purge linux-image-3.19.0-43-generic

There’s no power button on this weird machine, it boots when you plug it in.  My workaround for powering it off is that I’ve set the grub timeout to 3 minutes. Reboot, then unplug it at the grub menu.

Way back in 2010, I set up Southside XO Techs on Blogspot (or Blogger or whatever Google’s Blogging service is called now).  That’s where I made notes on XO and XS stuff.

Anyway, now that I’ve got this WordPress thing, I went ahead and migrated the content from there.  That’s why you’re seeing posts in the archive here starting from 2010 even though I set this up for work practice in March of 2015.

I guess I’ll leave that blog up over there, though I haven’t posted to it in years.  Exporting and importing the xml file with all the posts was really easy.  Though it kept the image links the same, pointed at Blogspot, so I had to manually fix the images to be hosted here.

I’ve been meaning to move this WordPress installation to its own cPanel account and subdomain.  While I was at it, I updated WordPress and switched to the 2016 theme.

This is still a crappy site with barely any content, cause I basically just use it for practice for work, but hopefully it’s more secure now.  Oh, and I got a free SSL cert from our favorite CA – Startcom.
