# Installation

IPTraf is most readily available on the Internet, but some may receive it on a diskette. Here are the instructions for both types of distributions.

## System Requirements

IPTraf requires:

### Hardware Requirements

- 16 megabytes of physical RAM (more recommended, at least 64 MB for very busy networks)

- 2 megabytes of free disk space for installation (more will be needed if you log high amounts of traffic over time)

- Pentium-class processor or higher (Pentium-II 200 MHz or higher recommended) or equivalent.

- One or more of the supported network interfaces.

### Operating System Requirements

- Linux kernel 2.2.0 or higher

- GNU C Library 2.1 or later

- ncurses 4.2 or later with the complete terminfo database in `/usr/share/terminfo`. Support for `linux`, `vt100`, `xterm`, `xterm-color` recommended.

### Compilation Requirements

The following components are required when compiling IPTraf from the source code.

- gcc 2.7.2.3 or later

- GNU C (glibc) development library 2.1 or later

- ncurses development libraries 4.2 or later

## Availability

IPTraf can be downloaded from the Internet from the official FTP site at ftp://iptraf.seul.org/pub/iptraf/.

The software is available in source form in compressed `.tar.gz` files named `iptraf-`x.y.z`.tar.gz` where ``x.y.z`` is the version number. Precompiled ready-to-run software is available in the `iptraf-`x.y.z.machinetype`.bin.tar.gz` files. (``machinetype`` indicates what platform the precompiled binaries run on. The official distribution will only be for the Intel x86 architecture indicated as `i386`.)

## Installing Downloaded Packages

You will need to have GNU tar and GNU zip installed. All modern Linux installations already have these utilities ready.

1. Decompress the `.tar.gz` file by entering

       tar zxvf iptraf-x.y.z.tar.gz

   for the source code or

       tar zxvf iptraf-x.y.z.i386.bin.tar.gz

   for the precompiled x86 programs.

   If your tar doesn't support the z option, you can separately decompress the `.tar.gz` file then extract the resulting `.tar` archive.

       gunzip iptraf-x.y.z.tar.gz
       tar xvf iptraf-x.y.z.tar

   This will decompress the sources into a directory called `iptraf-`x.y.z`` (source code) or `iptraf-`x.y.z`.bin` (precompiled). (`x.y.z` here should be the IPTraf version number you're installing, like `3.0.0`).

2. Change to the created top level directory.

3. To compile and install the software, run the Setup program by entering

       ./Setup

   while you are logged in as root. The Setup script will recognize the source distribution and compile the software before installing. It will immediately install a precompiled distribution.

The resulting binaries will be placed in the `/usr/local/bin` directory. All needed directories will also be created.

After installation, you will be asked if you want to read the `RELEASE-NOTES` file. It is recommended that you do so at that point, since the `RELEASE-NOTES` file contains important information about the new version.

## Installing a Floppy Distribution

If you received IPTraf on a diskette, the sources are already decompressed. The diskette is in Second Extended filesystem format. Perform the following steps to install the software.

1. Insert the floppy in the drive.

2. Mount the floppy on an empty directory. For example, to mount the floppy in the first floppy drive under a directory called `/mnt`, enter

       mount -t ext2 /dev/fd0 /mnt

   This assumes your floppy is in `/dev/fd0`. You can use any empty directory in place of `/mnt`. With most Linux installations, this will work fine.

3. After mounting, change to the `/mnt` (or whatever) directory.

4. Enter

       ./Setup

   while logged in as root. Setup will determine whether the diskette contains a source code distribution or ready-to-run precompiled software. This will copy the binaries to `/usr/local/bin`, and create the necessary working directories.

5. Unmount the diskette by typing

       umount /mnt

   (That's umount, not unmount.)

   You can then eject the diskette. Store it in a safe place.

   You will also be asked if you want to view the `RELEASE-NOTES` file. It is recommended that you do so at that point.

   In both cases (downloaded and floppy), the installation will store the program in `/usr/local/bin` with the binaries owned by user root, readable, writable, and executable by the owner, no permissions for the group, no permissions for all others. (700 octal, or `-rwx------`).

   | Note
   | You must be `root` to do the installation. The old style of installation (cd src;make install) is still supported.

Be sure `/usr/local/bin` is included in your environment's `PATH` variable. You can edit the appropriate command in your login customization file (`.profile` for the Bourne-type shells, `.cshrc` for the C shell and its relatives).
