Migrate any mail server to hestiacp (vestacp fork)

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.

iptables geoip too many countries specified


Знадобилося заблокувати деякі країни однією строкою:

iptables -I INPUT -m geoip --src-cc

Але отримав таку помилку:

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

Edit Java Security Exception list in Linux

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

Вирішується достатньо просто:

echo "" >> ~/.java/deployment/security/exception.sites

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

YELLOW status in Elasticsearch

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}}'
