Martin AJ's questions

I've added this in the .htaccess the file located in the root of the project:

<Files *.php>
    Require host lamtakam.test lamtakam.com
    Require ip ::1 95.216.xx.xx
</Files>

I've used xx.xx to keep my real ip hidden in a public community, in reality, there are numbers instead of xs.

Now I need to call a file daily (using a cron job crontab) from the same server, something like this:

0 22 * * * wget /path/to/file.php

But I get this error:

--2020-09-13 13:33:55--  https://lamtakam.com/path/to/file.php
Resolving lamtakam.com (lamtakam.com)... 104.31.74.192, 172.67.174.239, 104.31.75.192, ...
Connecting to lamtakam.com (lamtakam.com)|104.31.74.192|:443... connected.
HTTP request sent, awaiting response... 403 Forbidden
2020-09-13 13:33:55 ERROR 403: Forbidden.

Note: I use Cloudflare and these IPs belongs to it: 104.31.74.192, 172.67.174.239, 104.31.75.192

Any idea how can I make file.php accessible when I can it from the same server? (And not from anywhere else)

I've installed ssl on both my pure-domain and www subdomain. They works as well. I need to redirect all http protocol requests to https. Here is the config of the apache:

<VirtualHost *:80>

    ServerName lamtakam.com

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html/myweb

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    RewriteEngine on
    RewriteCond %{SERVER_NAME} =lamtakam.com
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

</VirtualHost>

<VirtualHost *:80>
    ServerName www.lamtakam.com
    DocumentRoot /var/www/html/myweb

RewriteEngine on
RewriteCond %{SERVER_NAME} =lamtakam.com [OR]
RewriteCond %{SERVER_NAME} =www.lamtakam.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

</VirtualHost>

<Directory /var/www/html/myweb>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    allow from all
</Directory>

Any idea how can I make that redirection? Currently some cases works as expected and that redirection happens. The only domain that redirection doesn't happen for it is:

• http://www.lamtakam.com/questions

Noted that this doesn't work: (however not sure if I place it correctly in the configuration)

RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^(www\.)?lamtakam\.com$
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [END,NE,R=permanent]

I use Ubuntu 16.04 and everything was fine until I installed git on the server. Now apparently MySQL is stopped and it doesn't start.

Here is the result of mysql -V:

mysql  Ver 14.14 Distrib 5.7.20, for Linux (x86_64) using  EditLine wrapper

And here is the result of sudo /etc/init.d/mysql start:

[....] Starting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
failed!

An here is the result of mysql -u root -p<myPassword>

mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Any idea how can I fix the problem?

EDIT: Here is the result of systemctl status mysql.service command:

I use ubuntu 16.04 on my server and recently I've installed postfix MTA on my server following this tutorial.

The problem is the email I send goes into spam, not inbox. Any idea what's wrong and how can I fix it? Noted that my domain name isn't into black list. Because few months ago, I did in on another server and emails sent as well (they went into inbox).

Also I send email via command line interface like this:

echo "This is the body of the email" | mail -s "This is the subject line" <my_email>

What should I do now?

Also this is my /etc/postfix/main.cf file on the server and this is my DNS records on cloudflare:

I'm not good in English and I cannot understand what does this mean:

I've followed the first code block of image above and my current configuration looks like this:

. . . 
mydestination = $myhostname, lamtakam.com, Ubuntu-1604-xenial-64-minimal, localhost.localdomain, , localhost
. . .

What change should I make now?

Note: lamtakam.com is the same as example.com in my case.

I use Ubuntu 14.04 on my server and I've added these lines into /etc/ssh/ssh_config: (as it's mentioned here)

ServerAliveInterval 300
ServerAliveCountMax 2
ClientAliveInterval 300
ClientAliveCountMax 2

Now my server is broken :(. I cannot connect to it through neither regular SSH connection nor tunneling:

Regular SSH Connection:

Tunneling To MySQL For Accessing Databases On The Server

I really have valuable data into server's databases without any backup. Any idea?
