By default when you use FreeBSD’s BASH shell and if you hit Home, Del, Insert keys all of them just prints ~ (some garbage is printed ). To get rid of this problem, edit /etc/profile file and define key binding.

1) Open your bash global profile file:
# vi /etc/profile

2) Add following line to it:
export INPUTRC=/usr/local/etc/inputrc

3) Close and save the file

4) Open the file /usr/local/etc/inputrc and define / modify key binding:
# vi /usr/local/etc/inputrc

5) Append following config data:

set meta-flag on
set input-meta on
set convert-meta off
set output-meta on

“\e[1~”: beginning-of-line
“\e[4~”: end-of-line
“\e[5~”: beginning-of-history
“\e[6~”: end-of-history
“\e[3~”: delete-char
“\e[2~”: quoted-insert
“\e[5C”: forward-word
“\e[5D”: backward-word

IMPORTANT

The effect of installing phpmyadmin is to discard mysql host based authentication, as connections via phpmyadmin will appear to come from localhost. For this reason, phpmyadmin should be protected by .htaccess as described below.

Install

* ApacheWebServer

* ApacheNexusAuthentication

*

cd /usr/ports/databases/phpmyadmin

make

make install

ln -s /usr/local/www/phpMyAdmin /usr/local/www/data/phpMyAdmin

cd /usr/local/www/data/phpMyAdmin

cp config.inc.php.sample config.inc.php

vi config.inc.php

And change:

$cfg['PmaAbsoluteUri'] = ”;

$cfg['blowfish_secret'] = ”

$cfg['Servers'][$i]['auth_type'] = ‘config’; // Authentication method (config, http or cookie based)?

$cfg['ShowChgPassword'] = FALSE; // simple users or not

to:

$cfg['PmaAbsoluteUri'] = ‘https://yourhost.yourdomain/phpMyAdmin/’;

$cfg['blowfish_secret'] = ‘YourSecRet’

$cfg['Servers'][$i]['auth_type'] = ‘cookie’; // Authentication method (config, http or cookie based)?

$cfg['ShowChgPassword'] = TRUE; // simple users or not

* Add to /usr/local/etc/apache/httpd.conf:

<Directory /usr/local/www/data/phpMyAdmin>

Allow from all

AllowOverride All

</Directory>

* Create /usr/local/www/data/phpMyAdmin/.htaccess as shown in ApacheWebServer in the mod_auth_radius section, except instead of:

require valid-user

use

require user list-of-users

where list-of-users is a space separated list of trusted users

The reason for the .htaccess on the phpMyAdmin directory is to protect the mysql databases from unauthorized access. Often, mysql is configured to permit access from specific hosts, typically localhost, and weak passwords may be employed. phpMyAdmin will connect to the local database and appear to come from localhost, rendering useless mysql host based permissions.

  • Its too bad she won’t live. But then again who does?
  • My mother, I’ll tell you about my mother.  BANG.

The process is now complete, and applications may be installed or upgraded using the updated Ports Collection.

To run both processes consecutively, issue the following command:

# portsnap fetch update

phpMyAdmin-3.2.0 has been installed into:

/usr/local/www/phpMyAdmin

Please edit config.inc.php to suit your needs.

To make phpMyAdmin available through your web site, I suggest
that you add something like the following to httpd.conf:

Alias /phpmyadmin/ “/usr/local/www/phpMyAdmin/”

<Directory “/usr/local/www/phpMyAdmin/”>
Options none
AllowOverride Limit

Order Deny,Allow
Deny from all
Allow from 127.0.0.1 .example.com
</Directory>

===

add to /usr/local/etc/nginx/nginx.conf

location /phpmyadmin {

alias /usr/local/www/phpMyAdmin/;

}

dd if=/dev/random of=test bs=1m count=2

This will create 2.0M file called “test”.

This also works on linux, but he doesn’t understand “m” as unit.

I’m affraid /dev/random will be very slow for creating large files or benchmarking.

/dev/urandom is the choice to go with.
