Mail server installation EXIM4

Posted by Pablo Gonzalez on July 3 2012rd

Good afternoon, in this article we will see how to makeMail server installation EXIM4with a dynamic IP address.

Personally, I do not recommend this configuration because we have serious problems blocking blacklist, so, this article has only academic value. To inspire the reader to other servers and services.

We start from an installation of GNU / Debian default 6 in an old notebook.

Add repositories / Etc / apt / sources.list

deb squeeze main contrib non-free
deb-src squeeze main contrib non-free

rename with # the line that begins with deb cdrom.

We enter the following command with the username root:

aptitude update (With this update we have added the repositories above).

Install the no-ip client, since I have dynamic ip address and in many cases (the vast majority) must match the domain to your ip when mail is delivered, otherwise, the target server will consider it as spam. I assume that you generate a suitable account if necessary.

We can decompress with xvzf tar noip-duc-linux.tar.gz and we will create a folder.

We continue with the following commands:

cd-2.1.9-1 noip

make install noip2.c

We requested email address, password and the update interval, which in my case I have considered going down to 5. We also ask if you want to run any programs in each update, and in my case I select No.

We generated the configuration file non-ip2.conf. Megacrack read »

Training program on free software (Introduction)

Posted by Pablo Gonzalez on June 8th 2012

Some time ago, my colleague told me xavixaus help in the development of the environment Free softwarefor this blog.

Well, it's already time to start it, and first I would like to comment briefly on how we will organize it.

First we will make an introduction to this world and see some aspects legalwe need to know, whether we are users and programmers, case studies to try to put the different concepts and continue to appreciate Basic management environments GNU / Linux(Choice of our distribution, installation, basic commands and routing).

The second part of this chapter will be the advanced administration in which address issues such as installation and compilation of the kernel and modules, NIS servers, exim4, LDAP, WebDav and Apache, authentication, snort, MySQL, subversion ... and something more ...

In the next module we will give some management, A staple for a migration to free software environment, with guidelines and best practice guidelines. At this point we will refer to success stories in government.

I think it's also interesting to do a course on free software utilities such as DIA, LibreOffice, forges where to find substitutes to proprietary software, etc ...

Finally, I would like to end articles with networks, focusing on routers, security (basic), audio, video and IP telephony.

It is an ambitious plan for each chapter because many items will be generated and we would like to implement a test environment to display settings and "tweak" the system. This last point for now is an idea. We will gradually giving.

I hope you enjoy it and bear your opinions through comments.
