how can I lock a cell? 

Jovan Stosic March 10, 2021

Router do not have such feature for force Cell ID.

But using AT commands via SSH you could try to force Cell ID. There is a risk to lost connection, so remember to which Cell ID router was connected and save all commands and outputs which you was used for recovering.

Commands example:

root@Teltonika-Router:~# ifdown ppp

root@Teltonika-Router:~# /etc/init.d/gsmd stop

root@Teltonika-Router:~# microcom /dev/modem_cmd

ATE1

OK

AT+QCSQ=0

OK

AT+CGREG=2

OK

AT+CGREG?

+CGREG: 2,1,”2620″,”BCA9802″,7

OK

AT+QENG=”servingcell”

+QENG: “servingcell”,”NOCONN”,”LTE”,”FDD”,250,02,BCA9802,62,2850,7,5,5,2620,-109,-9,-80,15,18

OK

Thank you!

but i’m not not able to do this…stuck at AT+QNLOCK

What output you get after this command: AT+QENG=”neighbourcell”

Dears,

is it possible to implement a similar script to lock a 3g wcdma cell?

In my neighbourcell list I have something like this (RUT955):

AT+QENG=”neighbourcell”

+QENG: “neighbourcell”,”WCDMA”,3038,-935,495,-1000,-75,3,-32768,-

+QENG: “neighbourcell”,”WCDMA”,3038,-935,129,-1040,-115,3,-32768,-

+QENG: “neighbourcell”,”WCDMA”,3038,-935,200,-1060,-120,3,-32768,-

+QENG: “neighbourcell”,”WCDMA”,3038,-935,424,-1100,-145,3,-32768,-

+QENG: “neighbourcell”,”WCDMA”,3038,-935,3,-1050,-155,2,-32,-

+QENG: “neighbourcell”,”WCDMA”,3038,-935,35,-1140,-195,3,-32768,-

+QENG: “neighbourcell”,”WCDMA”,3038,-935,5,-1150,-200,3,-32768,-

+QENG: “neighbourcell”,”WCDMA”,3038,-935,330,-1180,-240,3,-32768,-

It there a QNWLOCK command to lock one of these cells?
Thank you

How can I create a keyboard shortcut for highlighting text in LO Writer? – Ask LibreOffice

Jovan Stosic February 23, 2021

Highlighting text is not an “action” on text. It is an additional attribute on a character.

To achieve your goal, you must first define a character style with the specific colour selected as Background. Give a name to this style. You can now give it a keyboard shortcut.

This shortcut is not auto-toggling like Ctrl+B or I. I suggest you also associate a keyboard shortcut to character style Default Style so that you can cancel the effect of highlighting from the keyboard.

dm-crypt

Jovan Stosic February 23, 2021

dm-crypt is a transparent disk encryption subsystem in Linux kernel versions 2.6 and later and in DragonFly BSD. It is part of the device mapper infrastructure, and uses cryptographic routines from the kernel’s Crypto API. Unlike its predecessor cryptoloop, dm-crypt was designed to support advanced modes of operation, such as XTS, LRW and ESSIV (see disk encryption theory for further information), in order to avoid watermarking attacks. In addition to that, dm-crypt also addresses some reliability problems of cryptoloop.

dm-crypt is implemented as a device mapper target and may be stacked on top of other device mapper transformations. It can thus encrypt whole disks (including removable media), partitions, software RAID volumes, logical volumes, as well as files. It appears as a block device, which can be used to back file systems, swap or as an LVM physical volume.

Some Linux distributions support the use of dm-crypt on the root file system. These distributions use initrd to prompt the user to enter a passphrase at the console, or insert a smart card prior to the normal boot process.
