Somehow, our Ubiquiti (UBNT) antennas beat thunderstorms, which then had to be repaired, changed and naturally tuned again. Therefore, I decided to make an automatic copy of the configuration.Continue reading “Backup Ubiquiti Device Configuration (UBNT)”
It was necessary recently to write a script that executes a sql query into the MySQL database.
# Description, here I wrote for others that the script is added to the crontab, so that it is not moved mysql -u USER -pPASSWORD -h 127.0.0.1 -e "UPDATE nika_system.abon SET otkl=0 WHERE depozit > '10' AND (otkl='-1' OR otkl='-2');";
In order for the script to run automatically, open the crontab file in any text editor (in the nano editor CTRL+X for the output and y/n for saving or canceling the changes):
sudo nano /etc/crontab
Add the following line to it:
0 9 * * * root /home/nika/scripts/reset_credit_nika.sh > /dev/null 2>&1
Now every day at 9 am the script will be executed.
Here is an example of daily automatic output of data from a sql table into a text file:
#!/bin/bash mysql -u USER -pPASSWORD -h 192.168.1.1 -s -N -e "SELECT id FROM nika_system.abon WHERE tarif=109;";
In /etc/crontab we add:
0 8 * * * root /scripts/freektb.sh > /srv/samba/dir/mirazh/$(date +%Y-%m-%d).txt
For security reasons, it’s better not to specify the password in scripts, see my article – Connecting to MySQL from localhost without entering a password
I noticed that some cheap managed network equipment can start working incorrectly in a few days or weeks, so I had an idea to write a reboot script and add it to the cron.
Content of the script:
#!/bin/bash ( sleep 5 echo "admin" sleep 5 echo "password" sleep 5 echo "reboot" sleep 5 echo "y" sleep 5 echo "quit" ) | telnet 192.168.1.10
sleep 5 means a pause of 5 seconds after each command, this value is optimal for long thinking equipment. For example, for client switches D-Link DES-3200 pause can be completely removed or set 1.
