Securing SSH

The best way of Securing your server via ssh is to let connection just from ssh key.
So how we do that ?
Generate a ssh key pair on your computer

# ssh-keygen

now youll have 2 files id_rsa &
so what you have to do is change the to authorized_keys

# mv authorized_keys

Go to your server via ssh try to connect somewhere with ssh just so that you
create a .ssh folder on your home folder, or you can even do it manually than get back to your pc and:

# scp authorized_keys

You can do that also to root but anyway.

Enable Drupal URL cleaner

Thanks to James Michael Dupont I was able to enable my Drupal’s Site Url cleaner.
Actually first you have to enable mod_rewrite module, than edit your virtual host so that
it includes the .htaccess file, than edit your .htaccess file and reload apache.

What you should do first is enable mod_rewrite module

# a2enmod rewrite

Than to make it easier to work edit change .htaccess to htaccess.conf on your drupal folder (mine: /var/www/drupal-7.0)

# mv /var/www/drupal-7.0/.htaccess /var/www/drupal-7.0/htaccess.conf

Before including some lines on your vhost go to /var/log/apache2/ and create some log files:

# touch drupal7-rewrite.log drupal_access.log  drupal_error.log  drupal-rewrite.log

So now you have to include htaccess.conf in your vhost, by adding these lines: Continue reading “Enable Drupal URL cleaner”

Fix SSH from disconnecting

I use ssh client a lot…Sometimes happens that it disconnects and to keep that session alive you can try this…

Global Configuration
open /etc/ssh/ssh_config file and add in the end :

ServerAliveInterval 60

Current user configuration
Do the same with  ~/.ssh/config file if you don’t have the file create it

Host *
ServerAliveInterval 60

Indent the second line with a space.

Per-host configuration
If you want to do this just for a single server then in ~/.ssh/config file type :

Host *
ServerAliveInterval 60

Thanks, hope it helps !
