Note: if the system you SSH from is ever compromised, then assume the passwordless targets are also compromised!

Seems my interest in Ubiquiti needs more research: [WayBack] Linus Torvalds – Google+: Working gadgets: Ubiquiti UniFi collection.
Hopefully by now I’ve time to re-design the WiFi coverage in the house and invest in a few of those access points.

Controller
service unifi stop mongod --repair --dbpath /srv/unifi/data/db service unifi start
https://unifi.ubnt.com/5.8.24.0/unifi/site/default/dashboard?d=############000000000#######000000000#######00000000######## where # are digits, 0 are usually zero digits and 5.8.24.0 is .0 prepended by the first 3 parts of your Unifi Controller Version (mine had Version 5.8.24-11016 at that time).
Splitting 5Ghz and 2.4Ghz SSIDs: two ways (I think the second is cleaner)
For both the first and second one, you need to configure under “Config” -> “WLANs”.
For the second one, you can clone from the first, then change the SSID names.

Two installation options for TigerVNC:
The [WayBack] TigerVNC viewer gives a bit more details on failing VNC connections than the stock OSX Screen Sharing.app does: after performing the logon, the connection would just stall, but TigerVNC would should “write broken pipe (32)” after the logon. Most of the linked search results indicated the VNC server was having a state problem.
So I restarted the VNC server, after which connections could be made again in both tools.
I actually prefer the stock Screen Sharing.app as:
open vnc://192.168.178.55:5900 if your VNC server is listening on 192.168.178.55:5900TIL that Apple’s “Screen Sharing” app is command-line accessible.
ssh username@hostname -L5910:localhost:5900open
vnc://username:password@localhost:5910

Somehow I managed to get a OnePlus phone to have the read data limit line stuck at ~5 gigabyte whereas the warning was at ~15 gigabyte.
This caused all sorts of havoc when I passed the 5 gigabyte mark: cellular data would turn off, I would get all sorts of warnings and – worst of all – I could not reset the red line.
The solution was at [WayBack] Unable to remove “Cellular data limit exceeded” notification even after changing the data limit on OnePlus 2’s OOS 3.5.5:
There are numerous discussions offering a solution to this:
- Goto
Settings>Backup & reset>Network settings reset.- Now select the affected SIM card
- Now click
Reset Settings.

Cool stuff if you want to make your own WOL devices out of spare parts.
From old to new:
They can be woken up by anything sending magic WOL packets, including Raspberry Pi (which cannot be woken up by them, though you could use a Whack-on-LAN for that).
Basically the Raspberry Pi cannot be woken up with WOL because of a few reasons:
It can be a WOL server though: [WayBack] Raspberry Pi As Wake on LAN Server: 5 Steps (with Pictures)

With the advent of WebSockets, it looks like TCP tunnels over HTTP/HTTPS are gaining more ground and I need to put some research time in them.
Some old to new links:
CONNECT requests are not supported by many HTTP proxies, especially in larger organisations, so chisel and crowbar have a much bigger chance there.
However, that is a VPN solution which is much broader than just a single TCP tunnel. You can so similar things with OpenVPN, but over HTTP/HTTPS, also requires CONNECT:
SoftEtherVPN seems to be more versatile though. I blogged about that before, but back then didn’t have needs for it yet. VPN over HTTPS: Ultimate Powerful VPN Connectivity – SoftEther VPN Project.

10 years after the publication of the [WayBack] Top 25 Most Dangerous Programming Mistakes, the list for me is still the same.
You can see this from the CWE/SANS revisions: 1.0 in 2009 until 1.0.3 in 2011: not much changed.
