Alpine Boot switcher
I boot from a USB boot drive using UEFI. Because of the UEFI boot, it just a matter of copying the files from the alpine ISO to a USB thumbdrive VFAT32 partition.

Securing rsync on ssh
Reference: positon.org You have 2 systems and you want to set up a secure backup with rsync + SSH of one system to the other. Very simply, you can use: backup.example.com# rsync -avz --numeric-ids --delete [email protected]:/path/ /backup/myserver/ To do the backup, you have to be root on the remote server, because some files are only root readable. Problem: you will allow backup.example.com to do anything on myserver.example.com, where just read only access on the directory is sufficient. ...

Yealink W52P
Yealink W52P So I was looking to replace my analog cordless phones mainly because I wanted to have a centralized way to maintain phonebooks. Right now I have two cordless phone that I have to manually enter phonebook entries on the two handsets independently. Initially I was thinking of getting small/cheap Android tablet and load it with a SIP soft phone. Trying with a couple of tablets I had was not very successful. On one hand my network topology did not work very well, on the other hand, the integration of the SIP soft phone with the directory and the other phone functions did not work as well as I expected. So when I came across the W52P, I was initially attracted to the low price. Grandstream had a cheaper phone, but it did not have remote phonebooks. After checking the documentation of the W52P, I confirmed that it did have a remote phonebook functionality. So bought it and tried it out. As a phone itself, it is about the same as the analog phones that it was replacing. The voice quality was pretty good. ...
