Q. i have a compaq presario 7470 with a 533mhz AMD k-6 processor, 15GB hard drive, and 256MB of ram. What linux firewall distrobution should i load up onto it? any other ideas besides a firewall for this machine? what else could i use it for?
i want to use it as an extra layer of protection to protect my home network (about 4 pc's, 1 mac, and 3 tablets) from "bad" things on the internet. i just wanted to load up a firewall distro, configure it ( i have configured a friends before, but never installed myself) and just let it run and protect me. A. I suggest pfSense. You will need 2 ethernet ports. PCI ethernet cards are cheap.

I have activated a port for a office but have internet connection problems?
Q. Recently I have activate a port for a office room and i'm gettting internet connection but if i type something in search it gives me connect to office or offline. I'm currently running a linux firewall do i need to do some setting? or what should i do to fix it?
A. Make sure the port you specifies is not interfering with other services that is using the same port. You can also flush all the port to see which port is having problem. Also make sure your internet daemon is running.
You can always ping your router or any outside network to see if it has internet connection.
I hope this help.
Linux Firewall on a home network?
Q. What would be the use of a linux firewall in a home network? Is there any point in making one?
A. The primary purpose would be to learn more about how firewalls, routers and IPTables work. It used to be that it took some big iron to run firewall and router software, "back in the day"
Today, of course, you can buy a $40 home router that does most everything you need
Here are some other reasons to set up a Liniux
1. you want to monitor all traffic in and out of your home network. Using a Linux machine as a router/firewall allows you to tap the Ethernet port with Wireshark and sniff the traffic coming to and from the whole network, not just one machine..
2. You want complete control of what all the machines can do and when they can do it on the network.
Home routers give you some control.
A Linux firewall/router gives you control that only a high priced router can give you.
Bandwidth allocation and limits are not available on low end home routers. Linux would give you the same controls as a full business router costing $500 or more.
But these days - mostly for fun and to learn

A. Some software is distributed in "Source form". This means you download a file containing all the source code for the application you want to install, unpack it, and compile it on your system. Compiling is the process of turning the source code into an executable binary. It is a fairly straight forward process.
Typically applications you must compile from source will come as a ".tar.gz", ".tar.bz2", or ".zip" file.
You'll probably want to operate from inside your home directory. If your user is (for example) username, your home directory will be /home/username/. Downloaded your zip file containing install files to /home/username/src. If you do not have a src directory, you can create it with the following "mkdir" (make directory) command:
Code:
mkdir /home/username/src/
So, we have our source package in /home/username/src/.
Change to the /home/username/src/ directory with the "cd" (change directory) command like so:
Code:
cd /home/username/src/
Use the "ls" (list directory contents) command, to see the file is present:
Code:
ls
We now need to unzip the zipped file, this is done differently depending on the file extension.
for files ending in .tar.gz, use:
Code:
tar -zxvf <filename>
(replacing <filename> with the name of the file).
for files ending in .tar.bz2, use:
Code:
tar -jxvf <filename>
for files ending in .zip, use:
Code:
unzip <filename>
You should now have a new directory, containing all of the source files. To confirm it exists, and to get its name, use the "ls" command again.
Code:
ls
we now need to go into the new directory, so use the cd command:
Code:
cd <directory>
This is where things will differ. Some packages will have an INSTALL or README file which will contain installation instructions. use "ls" to see if the software has an install or readme file. If it does have one, you can use the "more" command to read it, like so:
Code:
more INSTALL
Generally, the final 3 stages are as follows:
- Configure the installation
- Compile the software
- Install the binaries
The pre-installation configuration is done by executing ./configure:
Code:
./configure
This will perform some requirements testing on your system, and create a "Makefile" which will explain to the "make" utility how the software should be compiled.
The next stage is to compile the software, this is done using "make". When you run "make" it will read the instructions in the Makefile and build the application binaries.
Code:
make
The final stage is to install these binaries, ie, copy them to a more permanent location. Typically only the "root" user can do this, so you will need to swich to the root user with the "su" command:
Code:
su
Once you are root, install the binaries using the "make" command, followed by "install", like so:
Code:
make install
How can i unzip and rename the output a zip file using Linux CLI?
Q. my problem is that the files inside the zip have a windows non unicode titles so after i "unzip" ,linux fails to write them to the Hdd because of their kwirky names ,so is there a way to unzip and rename the output immidiatly?
A. Unzip seems to be flawed in this capability.
Although I know of no way to change file filename on extraction, you could try these options:
-p extract files to pipe (stdout). Nothing but the file data is
sent to stdout, and the files are always extracted in binary
format, just as they are stored (no conversions).
-a convert text files. Ordinarily all files are extracted exactly
as they are stored (as ``binary`` files). The -a option causes
files identified by zip as text files (those with the `t` label
in zipinfo listings, rather than `b`) to be automatically
extracted as such, converting line endings, end-of-file charac-
ters and the character set itself as necessary. (For example,
Unix files use line feeds (LFs) for end-of-line (EOL) and have
no end-of-file (EOF) marker; Macintoshes use carriage returns
(CRs) for EOLs; and most PC operating systems use CR+LF for EOLs
and control-Z for EOF. In addition, IBM mainframes and the
Michigan Terminal System use EBCDIC rather than the more common
ASCII character set, and NT supports Unicode.) Note that zip`s
identification of text files is by no means perfect; some
``text`` files may actually be binary and vice versa. unzip
therefore prints ``[text]`` or ``[binary]`` as a visual check
for each file it extracts when using the -a option. The -aa
option forces all files to be extracted as text, regardless of
the supposed file type.
-b [general] treat all files as binary (no text conversions). This
is a shortcut for ---a.
-b [Tandem] force the creation files with filecode type 180 (`C`)
when extracting Zip entries marked as "text". (On Tandem, -a is
enabled by default, see above).
-b [VMS] auto-convert binary files (see -a above) to fixed-length,
512-byte record format. Doubling the option (-bb) forces all
files to be extracted in this format. When extracting to stan-
dard output (-c or -p option in effect), the default conversion
of text record delimiters is disabled for binary (-b) resp. all
(-bb) files.
If you know the encoding format of the files inside the archive, read the whiteboard section of this post for a possible clue:
https://blueprints.launchpad.net/unzip/+spec/unzip-detect-filename-encoding
It might be easier to extract them and rename on a windows machine.
Are there any free programs to unzip compressed files?
Q. I used win zip for the free trial and it worked well, I liked it. But now my free trial is over and I'm without a program to unzip compressed files. Normally this isn't a big deal, but I need to download GIMP brushes or fonts to do photo manipulations. Anyone know of a good program to use for this purpose? It needs to be free all the time. I could use a free trial again for now but I'd really like to have a "free all the time" program for this. Thanks!
A. 7Zip is free always. But it only works on Microsoft's Winduhs, if I recall correctly.
If you are running Linux, gzip is already present. Plus, the file managers already know how to zip and unzip, so no addons are required.

The question then becomes what other services you want/need. And frankly, this also depends on what you are familiar with. If you've done the RHE isntall 25 times, then you know it well and it should be quick and easy. Likewise if you've done the Windows install 25 times, then it should be quick and easy. Otherwise, it's going to take longer in both cases.

You download the ISO. image of Linux Mint 9 then you need to create a Bootable LiveCD for installation
Linux Mint 9 can also be run direct from the LiveCD from Booting up without touching your Hard Drive
