Repurposing Old Smartphones for Home Automation | Linux.com | The source for Linux information

Posted by jpluimers on 2019/03/13

Interesting read and watch:

At the recent Embedded Linux Conference and OpenIoT Summit, Mozilla Technical Evangelist Dietrich Ayala proposed a simple and affordable solution to home automation: A discarded smartphone can handle some of the most useful home automation tasks without requiring expensive hubs and sensors — or risking data security in the cloud.

Accessing storage (NAS) over the Internet via FTP | FRITZ!Box 7490 | AVM International

Posted by jpluimers on 2019/02/13

Of course you don’t want this. So by the time you read this, the connection has been closed.

For testing some Internet of Shit stuff from a client that cannot do SFTP, I needed a temporary FTP accessible connection.

These links helped:

TL;DR:

  1. Preparing the USB stick:
    1. Ensure the USB disk is FAT/FAT32/NTFS
    2. Create a directory in the root of the USB disk for the FTP user (for now: FtpDirectory)
    3. Insert the USB disk in the Fritz!Box
  2. Logon to the Fritz!Box web UI
    1. Configure a user for FTP:
      1. In the menu, go to System, then FRITZ!Box Users
      2. Click Add user
      3. Name the user (for now: MyFtpUser)
      4. Ensure that user *only* has a checkmark for `Access to NAS contents`
      5. Click the button Add directory
      6. In the popup click Select folder
      7. Choose the FtpDirectory you just made
      8. Click OK
      9. Ensure the read and write checkboxes are enabled
      10. Click OK
    2. Configure the USB stick for FPT access
      1. In the menu, go to Home Network, then USB Devices
      2. Observe if the device is visible and has the correct file system (if not: ask AVM)
      3. In the menu, go to Internet, then Permit Access
      4. Click on the FRITZ!Box Services
      5. Ensure there is a checkmark at Internet access to your storage media via FTP/FTPS enabled
      6. At TCP Port for FTP/FTPS, fill in 21 (many IoT devices cannot use a different port)
      7. Ensure there is *no* checkmark at Allow only secure FTP connections (FTPS)
      8. Make a note of the value after FTP address (something like ftp://example.org:21`)
      9. Click Apply
  3. Test

SSH: Connection Reset by Peer – Server Fault

Posted by jpluimers on 2018/11/22

One occasion I had SSH throw a Connection Reset by Peer on my when was the SD-card of a Raspberry Pi started failing and the ext4 filesystem got mounted in read-only mode.

Then sshd was still listening on port 22, but since it could not write to disk any more, it threw a Connection Reset by Peer to the client.

It was on OpenSuSE Tumbleweed, but would failed just as well using Raspbian.

Lessons learned:

  • IoT hardware will fail.
  • ext4 breaks when the hardware breaks.
