Create new file and add the next lines inside (for example pushtogit.sh)
#!/bin/bash echo " ====================== running command from" $PWD cd $PWD git add . echo -n " ====================== commit message: " read message git commit -m "$message" git push -u origin master echo " ====================== done..." |
Save the changes and add the alias inside .bashrc
alias pushtogit="/home/USER/PATH/pushtogit.sh" |
Sudo is a powerful utility built in almost all Linux distributions and we have a bad news for you – a recent privilege escalation vulnerability (CVE-2021-3156) has been discovered.
The vulnerability affects all the following sudo versions:
All legacy versions from 1.8.2 to 1.8.31p2
All stable versions from 1.9.0 to 1.9.5p1
A successful exploitation allows any unprivileged user to escalate its privileges to root on the vulnerable host. Of course, since it’s a privilege escalation vulnerability, it requires access to a local user on the vulnerable host in order to actually exploit it.
To test your host for this vulnerability just execute the next command
sudoedit -s / |
In case you receive the next response
usage: sudoedit [-AknS] [-r role] [-t type] [-C num] [-D directory] [-g group] [-h host] [-p prompt] [-R directory] [-T timeout] [-u user] file ... |
your host is safe but in case you receive the something like
sudoedit: /: not a regular file |
please upgrade
For CentOS 7 and CentOS 8 this is not a problem (yum -y update sudo) but if you’re using CentOS 6 then there are no way to upgrade from the official mirrors (since CentOS 6 is EOL)
You can download the rpm files from HERE (https://www.sudo.ws/download.html#binary)
Or directly
https://github.com/sudo-project/sudo/releases/download/SUDO_1_9_5p2/sudo-1.9.5-3.el6.x86_64.rpm
https://github.com/sudo-project/sudo/releases/download/SUDO_1_9_5p2/sudo-logsrvd-1.9.5-3.el6.x86_64.rpm
Then install the rpms with
rpm -U sudo-1.9.5-3.el6.x86_64.rpm rpm -U sudo-logsrvd-1.9.5-3.el6.x86_64.rpm |
NTP stands for Network Transport Protocol and it is used to keep the time on the servers synced with each other using a common reliable source to get the time.
The example below is for a basic NTP client/server setup.
NTP client
Install NTP with
yum install ntp |
Then check timezone with
timedatectl |
If you’re not satisfied with your timezone and you wish to change, first list available zones with
timedatectl list-timezones |
and set your time zone with command below: (e.g. Berlin)
timedatectl set-timezone Europe/Berlin |
Active the NTPD service at boot:
systemctl enable ntpd systemctl start ntpd |
To get a basic report you can use commands ntpstat or date
And to get some information about the time synchronization process
ntpq -p |
All of your NTP configurations is available in /etc/ntp.conf file.
To be able to use your server as a NTP server for local network, please be sure you have a line
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap |
where 192.168.1.0/24 is a local network you want to sync with your NTP server.
You can get the public NTP servers specific to your region from pool.ntp.org.
As of Laravel 5.5.13, there’s a new feature that allows you to blacklist certain variables in config/app.php under the key debug_blacklist.
When an exception is thrown, whoops will mask these values with asterisks * for each character.
To activate this feature, add the next lines inside config/app.php
... 'debug_blacklist' => [ '_ENV' => [ 'APP_KEY', 'DB_PASSWORD', 'REDIS_PASSWORD', 'MAIL_PASSWORD', 'PUSHER_APP_KEY', 'PUSHER_APP_SECRET', ], '_SERVER' => [ 'APP_KEY', 'DB_PASSWORD', 'REDIS_PASSWORD', 'MAIL_PASSWORD', 'PUSHER_APP_KEY', 'PUSHER_APP_SECRET', ], '_POST' => [ 'password', ], ], ... |
Save the file and clear the config cache with
php artisan config:clear
After this, all keys added inside debug_blacklist array will be replaced with asterisks (************)

The latest Skype for Linux update (8.13.) seems broken on Ubuntu 14.04/Mint Linux 17.x. The application loads but all I can see is the white window with the menu.
During load, I see the application screen for a second before the center of the application window turns white again. Reinstall process didn’t help
Since official fix doesn’t exist (for now), the only solution is to remove the latest version and install the older one
sudo apt-get remove skypeforlinux sudo apt-get install skypeforlinux=8.11.0.4 |
optionally you can “lock” Skype so it won’t ask for update (at least until they fix this problem)
sudo apt-mark hold skypeforlinux |
The idea to build and use the phone OS which doesn’t rely on Apple or Google is quite old. Since the Ubuntu Edge project, there have been several attempts, but nothing which can even scratch those two giants.
The new attempt is here – The Purism project, which is seeking funds right now (link here). The idea is to build a true Linux powered smartphone that focuses on security by design and privacy protection by default.
The device will ship with GNOME Shell UI or KDE Plasma Mobile UI by default. Also, through various partnerships and development efforts in the community, the users will be able to replace it with other UIs!
Once again, here is the LINK. Pledges starts from $20 so you can support it if you like.
Some PHP packages may stop working after update with error message: “There is no suitable CSPRNG installed on your system”.
The reason for this that they stopped using OpenSSL and now they need access to /dev/urandom which isn’t readable by your PHP configuration.
To fix this problem, all you need to do is to add /dev/urandom to your open_base configuration which limits the files that can be accessed by PHP to the specified directory-tree (or trees).
In case you’re using php-fpm, add the “/dev/urandom” in existing php_admin_value[open_basedir] definition (or add this line if it doesn’t exist)
For example:
php_admin_value[open_basedir] = /var/www/html/domain.tld:/usr/share/php5:/usr/share/php:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin:/dev/random:/dev/urandom |
or if you’re using mod_fcgi, inside .php-fcgi-starter script add parameter
-d open_basedir="/var/www/html/domain.tld:....:/dev/urandom" |
If you’ve just installed CentOS 6.x on software RAID and it won’t boot from /dev/md0, don’t worry. It can be fixed.
– Insert CentOS media/DVD and boot in rescue mode (select “Rescue mode” during boot)
– Select the “start shell” option
– chroot with
chroot /mnt/sysimage |
– install GRUB into /dev/md0 with
grub-install /dev/md0 |
– enter exit and than reboot
The other option is to enter into rescue mode and inside grub shell type the next commands:
grub> device (hd0) /dev/sda grub> device (hd1) /dev/sdb grub> root (hd0,0) grub> setup (hd0) grub> root (hd1,0) grub> setup (hd1) grub> quit |
Default “Java” version of Mint Linux 17.3 (or Ubuntu 14.04) is OpenJDK 1.7 which works fine, but some SDKs won’t install until you upgrade to 1.8 (for example Tizen IDE studio complains on OpenJDK 1.7)
Before you start, check the current version with “java -version”
java version "1.7.0_121" OpenJDK Runtime Environment (IcedTea 2.6.8) (7u121-2.6.8-1ubuntu0.14.04.1) OpenJDK 64-Bit Server VM (build 24.121-b00, mixed mode) |
Add the PPA, update and install oracle-java8-installer
sudo apt-add-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer |
(During the install process you’ll need to accept the Oracle terms)
Now, check again with “java -version”
java version "1.8.0_111" Java(TM) SE Runtime Environment (build 1.8.0_111-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode) |
In case you’re still receiving the 1.7 versions as response, install “oracle-java8-set-default” package with
sudo apt install oracle-java8-set-default |
and check again.
