We all know how beautiful vestacp and hestiacp are. Especially hestiacp :)
Exim4 is installed out of the box, but one little thing is missing - workable blacklist and whitelist.

My friend asked me to help with the migration of mail from a server running ispmanager5 lite to a server running vestacp. But this script is suitable for migration from any imap server to hestiacp panel.
I found imapsync utility and I'll use it. The email.txt file should contain a list of mailboxes and passwords, one account per line.

Create server:
hcloud server create --name=myserver --image=ubuntu-18.04 --type=cx31 --datacenter=hel1-dc2 --ssh-key=vitich

List our servers to get server ID:
hcloud server list

Add floating-ip
hcloud floating-ip create --type=ipv4 --home-location=hel1

List floating-ip to get floating-ip ID:
hcloud floating-ip list

Знадобилося заблокувати деякі країни однією строкою:

iptables -I INPUT -m geoip --src-cc
AR,BR,CN,CO,DZ,HK,IN,IR,KP,LA,MY,OM,PK,SC,TH,TW,VN -j DROP

Але отримав таку помилку:
iptables v1.6.0: geoip: too many countries specified

Оскільки я використовую кастомне ядро - я збираю xtables-addon самостійно.
Отже, нам потрібно збільшити XT_GEOIP_MAX та перезібрати.

I have been using this weather service for several years. Almost no problems.
Add to your conky config:
${texeci 300 curl -A "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.131 Safari/537.36" http://wttr.in/Kyiv_0pq_transparency=200_lang=uk.png -o $HOME/.conky/out.png}
${image $HOME/.conky/out.png -p 0,0}


I have two FullHD monitors and I want to launch the browser in kiosk mode so that Google will always open on the first monitor, and Facebook on the second one.
Let's specify the position, window size and path to the browser profile.
First monitor:

If I run skypeforlinux on openbox or lxde I get some crappy tray icon:

But if I run env XDG_CURRENT_DESKTOP=Unity skypeforlinux everything works fine.

1) install ansiweather
2) add to your conky config
${texeci 300 ansiweather -l Kyiv,UA -u metric -s true -d true -a false | awk '{split($0,a,"-"); print a[1]; print a[2]; print a[3]; print a[4]; print a[5]}'}

Or run in terminal:

Якщо ви користуєтеся IP-KVM / iLO / IPMI то мабуть Ви стикалися з помилкою "java application blocked by security settings".

Вирішується достатньо просто:

echo "https://10.0.0.1" >> ~/.java/deployment/security/exception.sites

Якщо хочеться додати всі можливі адреси в локальній мережі, то робимо скрипт і додаємо свої мережі:

The status is yellow because we have unassigned shards.
In this case we have one node cluster, but our indices all have number_of_replicas: 1 (which is the default). So we have to add a second node to our cluster, or just set "number_of_replicas: 0" globally:
curl -XPUT -H "Content-Type: application/json" 'localhost:9200/_all/_settings' -d '{"index" : {"number_of_replicas" : 0}}'
