Cargo Bike Tire Sizes

I was needed to buy some new tyres for my cargo bike.  I couldn’t see the tire sizes on the tire and no-one seems to put the specs on the internet.  After some measuring, I can confirm that the tires are:

  • Front Tires – 20″ x 1.75
  • Rear Tire – 26″ x 1.75

I hope this helps someone.

Bluetooth Really Quiet / Low Volume on Bluetooth iPhone

I have an Audio Pro T10 bluetooth speaker. I use it to play music from my iphone. For some reason this morning, when I tried to use, I could not hear any music coming out. The iphone was connected and playing music. I tried my wife’s phone and this played perfectly. I finally realised that the music was coming through but really quietly at a really low volume.

It seems that you have reset your bluetooth connection. Go into bluetooth setting. Click the information button.


Then forget the device.


Then re-pair the phone with the bluetooth speaker.  The sound should then work again.  If it doesn’t then repeat the process.

OpenSSH Xauth Command Injection Vulnerability – Ubuntu 14.04 – PCI Compliance

I’m just going through PCI Compliance for a company that I work for. The security scan picked an apparent vulnerability in the open-ssh server. The vulnerability had been patched in Ubuntu 14.04 and so this is a false positive. I thought that I post put about it because I found lots of posts where people are trying to compile their the latest open-ssh servers to get around this problem – when in fact it isn’t actually a problems. Compiling your own version of the open-ssh server isn’t recommended because you will have to continually patch the package yourself from then on.

The warning text said:

OpenSSH (OpenBSD Secure Shell) is a set of computer programs providing encrypted communication sessions over a computer network using the SSH protocol.

The sshd server fails to validate user-supplied X11 authentication credentials when establishing an X11 forwarding session. An authenticated user may inject arbitrary xauth commands by sending an x11 channel request that includes a newline character in the x11 cookie.
Please note that Systems with X11Forwarding enabled are affected.

Affected Versions:
OpenSSH versions prior to 7.2p2
An authenticated, remote attacker can exploit this vulnerability to execute arbitrary commands on the targeted system.
Users are advised to upgrade to the latest version of the software available. Refer to OpenSSH 7.2p2 Release Notes for further information.

Following are links for downloading patches to fix the vulnerabilities:

OpenSSH 7.2p2
SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.8 detected on port 22 over TCP.

I hope this is helpful to someone.
