How to change time from command line without messing up with SSL handshake












0















I am using Linux in an embedded machine and would like to implement time/date change functionality. I discovered and tried to use timedatectl, but it caused a couple of problems in my Qt application.



What I do when I want to change time is,



timedatectl set-local-rtc true

timedatectl set-ntp false

timedatectl set-time .....

hwclock --systohc


I can always get back to using Network time with:



timedatectl set-local-rtc false

timedatectl set-ntp true


However, as soon as I set NTP to false, I get SSL handshake errors (i.e. QML Image: SSL handshake failed) when I try to make a request from an API in my Qt application. This problem occurs at several places. I simply want to be able to turn on/off network time and adjust time on a Linux system. Any ideas how to tackle this issue would be greately appreciated.

          Accessing regular linux commands in Huawei's Dopra Linux

          Image
          4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
