Working Android Marshmallow (6.0) for Nexus 7 (2012) – Update 2

In my blog post from Sep. 2015 (Speeding up Nexus 7 (2012) Tablet after Lollipop upgrade) I evaluated several options to get the Nexus up to speed again even with Android 5 (Lollipop).

But even with the changes in place I still got a lot of lag and unresponsive apps. I considered a downgrade to 4.4 when I noticed that there is a Android M Firmware for the Nexus 7 on XDA-Developers.

Stalled connections using SCP/SFTP/SSH with large files through VPN connections

Sometimes you have to push data using SCP/SFTP/SSH via a VPN connection on a customer server. Especially if Cisco VPN hardware is being used and the files are large, the transfer sometimes is stalled and fails even. This also happens with other hardware as well and may be because of a poor implementation of SACK. It might help to switch SACK of in the kernel network stack.

How to mount a encrypted drive from a ISP backupserver using encfs and autofs. (update)

ISPs often offer external disk space, together with their server packages, to store several GB of data for backups. Usually this storage space can be accessed via ftp/sftp , nfs or cifs (Samba / Windows shared folder). But that usually means that our data is stored unencrypted on an external server we don’t control.

But there is quite an elegant solution to this using autofs and encfs to automount and encryt that storage space.
