SSH Apache server with Ubuntu Problem

S

i want to increase the security of SSH

service of our machine that is configured by default, we will do is change some options for extra safety file / etc / ssh / sshd_config

, but before you edit it, do a backup to restore the same, if we have something that we should not be amended by the following lines of code:

sudo cp / etc / ssh / sshd_config / etc / ssh / sudo chmod sshd_config.original a-w / etc / ssh / sshd_config.original

Once copied to a new file and write-protected can not change it, proceed to its amendment: 1. Assigned to the service port (22) as change by 5301. We sought

line "Port 22"
and instead write

"Port 5301" .


2. We set the maximum number of failed login attempts to 1. If you do not have it yet, add the line
"MaxAuthTries 1"

.

3. Indicate that the maximum number of concurrent unauthenticated connections are 2 with the following line "MaxStartups 2" .

4. Establish the direction of listening to our Private IP:
"ListenAdrress 192.168.2.100 (IP machine)"

.

5. Indicate which users can connect and from which IP:
"AllowUsers usuario@192.168.0.11"

6. We must also realize that probably, when administrators need to connect from any machine regardless of whether it is in our network or not, we must add a user for that purpose:
"user2 user3 user AllowUsers"

.

7. Finally, we disable the option to connect as root, to prevent external intrusion attempts, the line editing
"PermitRootLogin no"

.

If we complete even more security, you can set the permission of the host to attempt to connect to the service. For this we make the following changes:

1. In file / etc / hosts.deny

add the following line:
"ALL: ALL"

.

2.
edit the file / etc / hosts.allow and add the host

those who allow access. In this case we will do only a single computer.

"sshd: 192.168.0.104 (IP notebook)"
.

After saving the changes, we restart the service to take effect:

sudo / etc / init.d / ssh restart

. htaccess in Apache with Ubuntu

D e must bear in mind that with the default server will not recognize the file

. Htaccess
. To solve this problem we must modify a file in the Apache configuration, particularly in / etc/apache2/sites-available/default

, which modify the policy in our working directory line

AllowOverride None

For line AllowOverride All

Once the change will restart the service and solved the problem.

An example of this configuration is: \u0026lt;Directory

/home/usuario/httpd> AllowOverride All

Order Deny, Allow Allow from all

\u0026lt;/ Directory>

E-Learning 2010 (ELRN10)

Hi everyone, this new entry is intended to raise awareness of the expectations of the courses ELRN 2010. But before we begin, I would like to know is (ELNR).

ELRN is a course that will allow us to explore a set of concepts and trends related to the area of \u200b\u200blearning supported by information and communication technologies (ICTs). From this review, mission will develop a personal critical stance (although it seems redundant) on the issues of greatest concern to their immediate reality, to have a starting point for assessing the impact of computer technology (and other emerging technologies) in the formal education system.

In the first week of class will answer the following questions What do you hope to learn here? What questions to clarify expected? What are your initial perceptions about the course topic?

First Instance in what I hope is to delve into the subject matter and further strengthen my knowledge in such a way to apply it in my daily life and in my teaching. For Furthermore I hope that the questions that appear on the course and development of course be resolved in a clear manner. As for the perceptions I can say that it brings contextual elements to the reality of educational settings, and surely enrich the practice of university teaching or any other level.

I welcome your comment!
