Jenkins sometimes a little bit strange but it works at is.
you have addes a new ssh key and you got following error “you have requested strict checking”
Under configuration “Global Security” scroll down and choose what you need
look a the screen snipet, this config works well.
zypper remove package
will not work you got an error like this
In case ‘exmaple’ is not a typo it’s probably not a built-in command, but provided as a subcommand or plug-in (see ‘zypper help subcommand’).
In this case a specific package providing the subcommand needs to be installed first. Those packages are often named ‘zypper-exmaple’ or ‘zypper-exmaple’.
zypper remove -u package
In the good old days you are used ifdown and ifup and so you can bring up a network interface. Now you have systemd and you should use

networkctl shutdown interface
networkctl bring up interface
dmidecode | grep--color -i serial
how to install manually
but we want to compile itself and build a deb package
we need java and ant
apt-get install ant
Choose your version as source code
https://github.com/apache/tomcat/tags in our example we use 9.0.64
extract the folder and you can run /usr/bin/ant in the extraced tomcat folder after a frew seconds you can find your compiled tomcat under the folder /output/build
apt build-dep tomcat9
dpkg-buildpackage -rfakeroot -b -uc -u
MariaDB and MySQL sometimes realy strange. The last time I had offen dumps between sql server versions. you must not use my pipe for compression this is optional.
mysqldump –events –routines –triggers –single-transaction –default-character-set=utf8mb4 –opt database.dump | gzip > database.sql.gz
If you are need some stresstest for your MySQL server you can use mysqslap. I offen use this command
mysqlslap --auto-generate-sql --concurrency=100 --iterations=200
If you are searching for an alternative for Backblaze Backup. You can try rclone with s3 storage from Scaleway.
In these Blogpost you can find out how to install and configure it. But how to use it? I have some example for you.
Thats for a Windows machine, on Linux only other path K:test = /home/ubuntu/myfiles
rclone sync --progress K:\test Scaleway:allmybackup
If you want to store your data directly in to the GLACIER storage you can use
rclone sync --progress --s3-storage-class=GLACIER K:\test Scaleway:allmybackup
or you can configre rclone directly to use GLACIER directy without define storage class
Simple example if you are using encryption with rclone
rclone sync --progress K:\test crypt:
Now we have more options for bandwith usage
Attention rclone is using Megabyte not Megabit 1M are 8Mbit
rclone sync --progress --log-file=rclone_log.txt --bwlimit "06:00,2M 23:00,4M" K:\test crypt:
If you have a SQL cluster under heavy load you can use proxy sql but is nowhere an alternative software? Of course last month was publish ReadySet comes with a nice a GUI to analyze your cache.
If you have multi servers Linux Distribution and should check only Ubuntu. Then you can use this script to select the os and if only match the OS then execute the command.
if [ -e "/etc/issue" ] ;
set -- $issue
if [ $1 = "Ubuntu" ] ;
