Protect Ubuntu from Fork Bombs

In computing, the fork bomb is a form of denial-of-service attack against a computer system which makes use of the fork operation (or equivalent functionality) whereby a running process can create another running process.
A fork bomb works by creating a large number of processes very quickly in order to saturate the available space in the list of processes kept by the computer's operating system. If the process table becomes saturated, no new programs may start until another process terminates.

the following example may look innocent, but running it on an unprotected system may take the whole system down:

Do not run this code on an unprotected system!

$ :(){ :|:& }; :

The above shell script will actually keep forking at an exponential rate until system resources are exhausted.
To protect a system against such attacks, there is a file for limiting the number of processes per user. It is /etc/security/limits.conf. Add the following two lines to it:

*            hard       nproc                    20

user       hard       nproc                   300

or

@users          soft       nproc                  100
@users          hard       nproc                  150

These lines prevent anyone in the users group from having more than 150 processes, and issue a warning at 100 processes.
Your system may not have a users group, so you may want to edit the lines to match your needs.

Mint Backup In Ubuntu

-----------------------------

Install MintBackup In Ubuntu

MintBackup: it can backup and restore files and directories (doh!) but not only that - it can also backup and restore your complete software selection (something you can also easily do via command line, but some are scared by the terminal) so you can install all the packages you had installed when you install a newer Ubuntu version.

Other MintBackup features:
It can check differences in files and perform incremental backups/restorations
It can check the integrity of the files after it copies them
It can backup straight to an archive and compress it on the fly

Since MintBackup is designed for non-geeks mostly, it can only do local backups so if you want something more advanced, I suggest you see what the WebUpd8 readers consider to be the best Linux backup tool.

Reserved IPv4 addresses

Reserved IPv4 addresses

The Internet Assigned Numbers Authority (IANA) has set aside a number of IPv4 address sectors for special purposes. But because the IPv4 address space has turned out to be insufficient and some reserved sectors are hardly used, some of this space has been made available again. RIPE organizes the issue of IP addresses in Europe. Users generally do not get them directly, however, but rather from their provider.
Information on addresses not listed here is provided at our whois search.

0.0.0.0/8
Host in "this" network. The address 0.0.0.0/32 designates the host itself. This address can only be used for source addresses, for instance for the assignment of DHCP and PPP before the host has received an address. Defined in RFC 5735, page 3.

10.0.0.0/8
Addresses for private networks; address need not be registered for use. They may not, however, be used on the public internet. RFC 1918 defines how these addresses are to be handled.

127.0.0.0/8
Loopback addresses: Each packet sent to one of these addresses is sent back internally instead of leaving the host. Defined in RFC 1700, page 4.

169.254.0.0/16
Addresses for automatic configuration (APIPA, Zeroconf). These addresses should only occur within this network. Defined in RFC 3927.

172.16.0.0/12
Addresses for private networks; address need not be registered for use. They may not, however, be used on the public internet. RFC 1918 defines how these addresses are to be handled.

192.0.0.0/24
Reserved, will be made publicly available if need be. Defined in RFC 5736.

192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24
Reserved as example addresses to be used in documentation (in a similar way the domain names example.com and example.net from RFC 2606 are used). Addresses in this range may not be used on the public Internet. Defined in RFC 5737.

192.88.99.0/24
RFC 3068 defines addresses that connect IPv6 networks via IPv4 ("6to4 anycast address").

192.168.0.0/16
Addresses for private networks; address need not be registered for use. They may not, however, be used on the public Internet. RFC 1918 defines how these addresses are to be handled.

198.18.0.0/15
Addresses for tests of network components. Defined in RFC 2544.

224.0.0.0/4
Multicast for the broadcasting of data from one sender to a select group of recipients. The IANA specifies the use of individual multicast addresses. Defined in RFC 3171.

240.0.0.0/4
Reserved for later use. Defined in RFC 1112

255.255.255.255/32
Address for limited broadcasting. It can only be used as a target address, and packets with that address should not be routed from the network they come from. Defined in RFC 1700, page 4.

Formerly reserved IPv4 ranges

14.0.0.0/8
Was reserved for a service for the transmission of IP packets via "Public Data Networks" (PDNs), such as protocol X.25 detailed in RFC 1356. Released in RFC 5735 as regular address space.

24.0.0.0/8
Was reserved for IP over TV systems, but managed by The American Registry for Internet Numbers (ARIN) now manages this address range. Defined in RFC 3330. Released in RFC 5735.

39.0.0.0/8
In 1995, this address range was reserved for the "Class A Subnet Experiment" (see RFC 1797). Released in RFC 5735.

128.0.0.0/16
Defined in RFC 3330. Released in RFC 5735.

191.255.0.0/16
Defined in RFC 3330. Released in RFC 5735.

223.255.255.0/24
Defined in RFC 3330. Released in RFC 5735.

Medibuntu:
"Medibuntu is a packaging project dedicated to distributing software that cannot be included in Ubuntu for various reasons, related to geographical variations in legislation regarding intellectual property, security and other issues:

* patentability of software, algorithms, formats and other abstract creation
* legal restrictions on freedom of speech or communication
* restrictions on the use of certain types of technical solution, such as cryptography
* legal restrictions on imports of software technology, requiring for example specific permissions
* etc...

A lot of excellent free software and non-free software is affected by such restriction somewhere in the world, thus preventing its inclusion into Ubuntu that, for economy and simplicity, are generally identical for all countries.

We refuse to resign ourselves to abandoning software that may be legally useful somewhere, and we have chosen to provide it with "professional" quality packaging, easily usable within the context of Ubuntu.
This repository provides packages for Ubuntu distribution."

It is your legal responsibility to make sure that the software you are installing can be legally used in your country and for your intended purpose."

HAVP - HTTP Anti-Virus Proxy

Using the HAVP anti-virus proxy to protect from web attacks

HTTP Anti-Virus Proxy (HAVP) is such a proxy, and it supports the integration of multiple parallel scanners including those that are completely free or available to home users free of charge. It only takes a few steps to have HAVP and additional scanners installed and ready for action on a current system such as Ubuntu 10.04.

In Ubuntu, ClamAV can simply be installed by opening a Terminal Ctrl+Alt+T ;

$ sudo apt-get install clamav

and then manually running sudo freshclam once to update the signatures. Doing this means that the current signatures become available immediately; the service will download signature updates automatically once a day from then on.

For the next step, install HAVP by running

$ sudo apt-get install havp

Ubuntu will launch HAVP in the background, but with only a default configuration file. This file can be opened by running

$ sudo gedit /etc/havp/havp.config

To make HAVP accessible through the net and allow it to accept more than just local connections, the BIND_ADRESS 127.0.0.1 entry must be commented out with a hash sign (#) at the start of the line. Setting ENABLECLAMLIB to true tells HAVP that it can use the ClamAV scanner via the library function – other third-party scanners supported by HAVP listen on either TCP ports or on Unix domain sockets.

Enter

$ sudo /etc/init.d/havp restart

to integrate the custom configuration into HAVP. To run a first test in your web browser, enter the address of the server as the proxy and 8080 as the port. Launching the test files at Eicar.org should now provoke a HAVP alert in the browser window, warning you that ClamAV has detected a virus. So far so good, but unfortunately the detection rates of ClamAV is relatively low compared to other scanners. Thankfully, version 0.91 of HAVP also supports the Linux version of the virus scanner by vendor AVG Technologies, which is freely available to home users and provides more respectable detection results.
