Mosh: mobile shell (ssh replacement) with roaming support and supporting intermittent connectivity

Recently I was confronted with very low data throughput on my mobile data connection. Because of the high latency you have to wait a long time for the server reply before you can even see you your own typing. That’s really awful. In addition, dropping connections can really be a problem.

The solution is Mosh – the mobile shell. The key features are:

– allows roaming
– supports intermittent connectivity
– provides intelligent local echo and line editing of user keystrokes

The installation is easy. For debian type

 apt-get install mosh

That’s it.

Now you have to open a suitable port (UDP) in your firewall. I chose 63310.

OpenWRT wireless non-spooling printserver

With p910nd, a small daemon acting as non-spooling printserver, it’s easy to get non WiFi or non Ethernet Printers in your network. I use this configuration for a Brother (QL-500) labelprinter. You must have installed the regular printer drivers on your PC.

At first you have to install a few packages:

opkg update

opkg install kmod-usb-printer p910nd


Then you can connect your printer and turn it on. Run dmesg and look for entries like

[ 10.530000] usb 1-1: new full-speed USB device number 2 using ehci-platform

[ 10.570000] usbcore: registered new interface driver usblp
[ 10.750000] usblp0: USB Bidirectional printer dev 2 if 0 alt 0 proto 2 vid 0x04F9 pid 0x2015


Change the config file /etc/config/p910nd to the following (assuming you connect a usb printer to the OpenWRT device):

Install Debian on MiniX NEO X7

notice NOTICE: Your Minix will boot from SD-Card automatically. Internal Flash will not be used and won’t be available.

To install Debian on the MiniX NEO X7 you need:

– a SD Card (minimum 4GB)
– a Linux Machine
– a Windows Machine
– these both zip-files: (needed on the linux machine) & (needed on the windows machine)


At first boot up your Linux Box, and insert your SD Card.

Find the right partition of the SD Card, it should contain only one partition:

cat /proc/partitions

Then format the partition as ext4:
