Aero AIO: Folding@Home is a plugin for Aero AIO to monitor your Folding@Home client. It comes with a simple configuration dialog to set the update interval and client path.

It was inspired by navyrains folding-karamba theme.

Folding@Home is a distributed computing project to understand protein folding, misfolding and related diseases (http://folding.stanford.edu).

File::Save::Home is a Perl module to place file safely under user home directory.

SYNOPSIS

use File::Save::Home qw(
get_home_directory
get_subhome_directory_status
make_subhome_directory
restore_subhome_directory_status
conceal_target_file
reveal_target_file
make_subhome_temp_directory
);

$home_dir = get_home_directory();

$desired_dir_ref = get_subhome_directory_status("desired/directory");

$desired_dir_ref = get_subhome_directory_status(
"desired/directory",
"pseudohome/directory", # two-argument version
);

$desired_dir = make_subhome_directory($desired_dir_ref);

restore_subhome_directory_status($desired_dir_ref);

$target_ref = conceal_target_file( {
dir => $desired_dir,
file => file_to_be_checked,
test => 0,
} );

reveal_target_file($target_ref);

$tmpdir = make_subhome_temp_directory();

$tmpdir = make_subhome_temp_directory(
"pseudohome/directory", # optional argument version
);

In the course of deploying an application on another users system, you sometimes need to place a file in or underneath that users home directory. Can you do so safely?

This Perl extension provides several functions which try to determine whether you can, indeed, safely create directories and files underneath a users home directory. Among other things, if you are placing a file in such a location only temporarily -- say, for testing purposes -- you can temporarily hide any already existing file with the same name and restore it to its original name and timestamps when you are done.

Script for a multi-homed firewall is an example IPTables 1.2.1 script for a dual-homed firewall.

This script has not yet been tested thoroughly on a dual-homed firewall. If you find any problems, please drop me an email.

## User-defined Chains ##

Chain KEEP_STATE
The KEEP_STATE chain holds a few rules for generic stateful packet filtering.
This chain is called from many of the INPUT/OUTPUT chains to DROP "INVALID"
and perhaps "UNCLEAN" packets and allow other packets from "RELATED" or
"ESTABLISHED" connections.

CHECK_FLAGS
The CHECK_FLAGS chain contains a few rules to filter based on TCP flags.
These rules do indeed filter mainly bogus/malicious traffic(scans, etc). It
would be a good idea to keep an eye on what these rules send to the logs.
Null scans are also logged and dropped, in the mangle table.

DENY_PORTS
The DENY_PORTS chains contains a few rules to DROP and/or LOG packets based
on the source and/or destination port number of the packet.

Packets destined to/from the following ports are dropped by default in the script. These are just some examples of some commonly used ports that certain daemons/trojans/DDoS agents may utilize.

## TCP ##
137:139 SMB
2049 NFS
6000:6063 X
20034 Netbus 2 Pro
12345:12346 Netbus
27374 SubSeven
27665,27444,31335 Trinoo
10498,12754 Mstream

## UDP ##
2049 NFS
31337 BO2k
27444,31335 Trinoo
10498 mstream

These are just examples to stare at. They guarantee no real protection against the associated trojans.

For more common port numbers check out:

ALLOW_PORTS
The ALLOW_PORTS chain simply ACCEPTs packets based on port number. If you have
a default FORWARD policy of DROP, then you would need to utilize a chain like
this if you are DNATing/routing connections behind the firewall or perhaps
running services on(!!!) the firewall.

ALLOW_ICMP
The ALLOW_ICMP chains simply allows packets based on ICMP type. Currently
the firewall allows the flow of the following ICMP types:
Echo Reply (pong)
Destination Unreachable
Echo Request (ping)
TTL Exceeded (traceroute)

SRC_EGRESS && DST_EGRESS
The SRC_EGRESS and DST_EGRESS chains filter packets that have a source or
destination IP address matching an array of private or reserved subnets.

TOS_OUTPUT
The TOS_OUTPUT chain exists in the mangle table and mangles the TOS(Type
of Service) field in the IP header of locally generated, outgoing packets.

TOS_PREROUTING
The TOS_PREROUTING chain exists in the mangle table and mangles the TOS(Type
of Service) field in the IP header of packets being routed through the firewall.

The following user-defined chains are pretty obvious. The firewall script is designed to have a user-defined INPUT and OUTPUT chain for every available interface. From these user-defined chains are called the user-defined chains
mentioned above, which I call "Special Chains". The chains below are then called by the built-in INPUT/OUTPUT/FORWARD chains. This isnt really the rule, of course, alot of the user-defined chains mentioned above are called directly from the built-in INPUT/OUTPUT/FORWARD chains. This is done to assure proper flow of the packets through the filters.

EXTERNAL_INPUT
INTERNAL_INPUT
DMZ_INPUT
LO_INPUT
EXTERNAL_OUTPUT
INTERNAL_OUTPUT
DMZ_OUTPUT
LO_OUTPUT
