GPIO Sensors Fun – Keyes DS18b20 1-Wire for the Raspberry Pi
I’ve been using my Raspberry Pi as a replacement for another bulky server/heating element I used two years ago. Since then, the Credit Card sized hardware with it’s 8 Gigabyte SD-card, has endured the role of a NTP, DNS, OpenVPN, HTTP and SSH-terminal server. With no crashes or slowdowns (within expectable limits) to speak of,…
How to: Mount remote storage using sshfs
For me, SSH has replaced three very flaky protocols. Telnet (true story) for an networked shell, FTP handling simple file transfers and finally NFS mounting network attached storage. SSH provides the -encrypted- networked shell, handles simple file transfers using SCP or SFTP, and has the power to mount filesystems using SSHFS. All in one protocol!…
How To: Monitor NetCat File Upload Progress using PV
Using NetCat to upload files can sometimes be handy, however it would be awesome if you could track the upload ETA and not just stare patiently for a prompt. PV, or “Pipe Viewer”, is a handy little command that allows you to track the progress of any Unix pipe. Using it as an replacement for…
How to: Piece together Port and PID using Netstat, In Linux
Linux and networking go hand in hand, whether running on the fancy desktop or noisy server. Regardless of which packages you choose to install, chances are, that they require networking for some functionality. A desktop may have some dns-cache, filtering proxy, anonymous socks or ssh-tunnel listening in the background. The server equally busy with its…
Axel, the Accelerated Wget
When downloading large files in Linux, wget gets the job done but isn’t very fast. When speed is of the issue, a multi-connection tool is needed. That is where axel, a simple command-line based download accelerator, comes in. Axel is as easy to use as wget, it may not have the advanced features such as…
