Network weathermap plugin for Cacti 1.0

Следвайки инструкциите на е възможно да имате отново работещ weathermap в Cacti 1.x. Все още има какво да се корегира по кода, но основната функционалност като визуализиране (без clickable maps) на weathermap и тяхното редактиране работят.

Ключови моменти на които трябва да обърнете внимание (quick & durty method for install):

cd /usr/local/share/cacti/plugins
tar zcvvf weathermap-backup.tgz weathermap/* && rm -rf weathermap
git clone
mv network-weathermap weathermap
cd weathermap
npm install -g bower
fetch -o composer-setup.phar
php composer-setup.php –install-dir=bin –filename=composer
bower install —allow-root
composer update –no-dev

Върнете съдържанието на вашата директория ./configs/*.conf от архива който сте направили ( в примера по горе наречен weathermap-backup.tgz ).

tar xvf weathermap-backup.tgz weathermap/configs/*.conf

След това може да достъпите уеб интерфейсът на вашата cacti инсталация и да инсталирате и активирате отново weathermap plugin от settings.

Quick way to upgrade from PHP5.6 to PHP7.2 on FreeBSD

There are many reasons why anyone will need to switch to PHP 7.2 his machine – here, here, here and many more PoC …

Use script like attached bellow:

for FILE in `pkg info | grep php56 | cut -f1 -d’ ‘` ; do
PKGNAME=`pkg info „$FILE“ | grep ‘Origin’ | cut -f2 -d’:’` ;
NEWPKGNAME=“${PKGNAME//php56/php72}“ ;
echo „Replacing port $FILE with $NEWPKGNAME“ ;
portmaster -o „$NEWPKGNAME $FILE“ ;
portmaster pecl\*
portmaster pear\*

Next you should check that everything from dynamic libraries is correctly linked with command „php -v“.

Hints for some “missing“ packages:

portmaster -o devel/php72-intl pecl-intl-3.0.0_12
portmaster -o security/pecl-mcrypt php56-mcrypt-5.6.34

Using Hurricane Electric free DNS service for slaves

So apart from setting ns[2345] as your DNS servers at your registrar and adding a slave at you need to do the following:

  1. Allow transfer AXFR to Server that pulls zones is, not
  2. Remove from allow transfer ACLs if it was there.
  3. Set the server to send NOTIFY’s to Yes, to ns1, not to doesn’t listen for any DNS requests including NOTIFY’s.

BIND example

The NOTIFY part is a bit tricky, so here’s an example from my setup.

Creating an ACL for

At the top level of named.conf:

acl he-slaves
{; // IPv4
2001:470:600::2; // IPv6

Basic zone setup

zone "" in
type master;
file "data/";

Notification setup

Add this to the zone:

notify explicit;

So the zone looks like:

zone "" in
type master;

notify explicit;
{; //

file "data/";

PowerDNS 4 example

execute this commands on PowerDNS machine

pdnsutil set-meta ALLOW-AXFR-FROM AUTO-NS
pdnsutil set-meta ALSO-NOTIFY

The result can be checked via:

pdnsutil get-meta

Suppress warning messages using mysql from within Terminal, but password written in shell script

Here’s how I got my bash script for my daily mysqldump database backups to work more securely.
1. First use mysql_config_editor (comes with mysql 5.6+) to set up the encrypted password file. Suppose your username is „db_user“. Running from the shell prompt:

mysql_config_editor set –login-path=local –host=localhost –user=db_user –password

It prompts for the password. Once you enter it, the user/pass are saved encrypted. Of course, change „system_username“ to your username on the server.

2. Change your shell script from this:

mysqldump -u db_user -pInsecurePassword my_database | gzip > db_backup.tar.gz

to this:

mysqldump –login-path=local my_database | gzip > db_backup.tar.gz

No more exposed passwords.
