IP network calculator

=====================

[![License Badge][]][License] [![GitHub Status][]][GitHub] [![Coverity Status][]][Coverity Scan]



netcalc is a slimmed down clone of [sipcalc][], using the output format

of [ipcalc][].  It is written in C and only depends on a POSIX compliant

C library.  Both IPv4 and IPv6 are supported.

Build & Install

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



### Debian/Ubuntu



    curl -sS https://deb.troglobit.com/pubkey.gpg | sudo tee /etc/apt/trusted.gpg.d/troglobit.asc

    echo "deb [arch=amd64] https://deb.troglobit.com/debian stable main" | sudo tee /etc/apt/sources.list.d/troglobit.list

    sudo apt-get update && sudo apt-get install netcalc



### Docker



Automatically built images available here:



* https://hub.docker.com/r/troglobit/netcalc



A Dockerfile is provided to simplify building and running `netcalc`.



    docker build -t netcalc:latest .

    docker run --rm netcalc:latest netcalc 172.16.10.10/16



### Building from Source



First download the latest official release from GitHub:



* https://github.com/troglobit/netcalc/releases



Always use the versioned tarballs, they contain all required files to be

able to build.



### Configure & Build



The GNU Configure & Build system use `/usr/local` as the default install

prefix.  Here we override that to use `/usr/`, the netcalc binary will

then be installed in `/usr/bin`:



    $ ./configure --prefix=/usr

    $ make -j5

    $ sudo make install-strip



### Building from GIT



If you want to contribute, or simply just try out the latest but

unreleased features, then you need to know a few things about the

[GNU build system][buildsystem]:



- `configure.ac` and a per-directory `Makefile.am` are key files

- `configure` and `Makefile.in` are generated from `autogen.sh`,

  they are not stored in GIT but automatically generated for the

  release tarballs

- `Makefile` is generated by `configure` script



To build from GIT; clone the repository and run the `autogen.sh` script.

This requires the GNU tools `automake`, `autoconf` and `libtool` to be

installed on your system.  Released tarballs do not require these tools.



    $ sudo apt install git automake autoconf



Then you can clone the repository and create the `configure` script,

which is not part of the GIT repo:



    git clone https://github.com/troglobit/netcalc.git

    cd netcalc/

    ./autogen.sh

    ./configure && make



GIT sources are a moving target and are not recommended for production

systems, unless you know what you are doing!



Origin & References

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



The original `sipcalc` project was created by Simon Ekstrand in 2001.

It is no longer actively maintained, but has a lot of features and is

available on major Linux distributions and works on *BSD and Solaris.
