TagSpaces File Organiser

TagSpaces is an open source personal data manager. It helps you organize files with tags on every platform. It helps you organize files with tags on every platform. Organize your photos, recipes or invoices in the same way on every platform. Cross platform support for Windows, Linux, OS X, Android, Firefox and Chrome. With the help of tags you can do research better or you can manage projects using the GTD methodology. The application persists the tags in the file names. As a consequence, the tagging information is not vendor locked and can be used even without the TagSpaces application. The absence of a database, makes syncing of the tag meta information easy across different devices with services like Dropbox. TagSpaces features basic file management operations, so it is a kind of tag-based file manager.

Open and Extensible

TagSpaces is open sourced and published under the AGPL license. It is designed to be easily extended with different plugins for visualization of directory structures or for opening of different file types.

No Backend – No Login – No Cloud

TagSpaces is running completely offline on your computer, smartphone or tablet and does not require internet connection or online registration. You can still use platforms like ownCloud, Dropbox or Bittorrent Sync in order to sync your files between devices.

Ease of use

TagSpaces offers you a convenient web interface to your local file system. It is implemented in JavaScript and HTML5, which are the technologies behind most of the modern web applications.

Mysterious cab files fill-up temp folder

A Windows server disk space is filling up fast due to cab files.

Upon closer inspection I found that every hour an unknown process would attempt to write a .cab file of approx 60MB to the Windows temp folder. Checking with Process Explorer I found that it was makecab.exe writing these files. Makecab was invoked by services.exe, so that was a bit of a dead end. I looked through the list of Windows scheduled tasks, but did not find anything that was supposedly run every hour.

The SFC.exe program writes the details of each verification operation and of each repair operation to the CBS.log file. The CBS.persist.log is generated when the CBS gets to be around 50Mb in size. CBS.log is copied to cbs.persist.log and a new cbs.log file is started. A bit of Google foo and we determine that the cbs logs would only be useful for serious troubleshooting issues. If the system is running fine, we can delete this file. SFC.exe will create a new one, next time it is run. I now speculate that the file size is larger than what is supported and the process fails, hence resulting in a partial .cab file that sits in the temp folder, rather than a complete .cab file in the CBS log folder.
I have deleted the offending .cab file and most of the other ones too, just keeping a few recent ones in case we need them. No more mysteries!

Shodan https://www.shodan.io/ is a search engine that lets the user find specific types of computers (routers, servers, etc.) connected to the internet using a variety of filters. Some have also described it as a search engine of service banners, which are meta-data the server sends back to the client.[1] This can be information about the server software, what options the service supports, a welcome message or anything else that the client can find out before interacting with the server.

Shodan collects data mostly on web servers (HTTP, port 80), as well as FTP (port 21), SSH (port 22) Telnet (port 23), SNMP (port 161), SIP (port 5060),[2] and Real Time Streaming Protocol (RTSP, port 554). The latter can be used to access webcams and their video stream.[3]

Test Internet connection speed with iperf in Linux

How do I test my Internet connection download speed from the console over the ssh session without using HTML5 or Adobe flash/Java applets based websites? How do I test my upload speed from the console?

You can use iperf utility for Linux – see https://iperf.fr/ iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). For each test it reports the bandwidth, loss, and other parameters. This is a new implementation that shares no code with the original iPerf and also is not backwards compatible. iPerf was orginally developed by NLANR/DAST. iPerf3 is principally developed by ESnet / Lawrence Berkeley National Laboratory. It is released under a three-clause BSD license.
