IP network calculator
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 apt-key add -
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:
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:
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-directoryMakefile.am
are key filesconfigure
andMakefile.in
are generated fromautogen.sh
, they are not stored in GIT but automatically generated for the release tarballsMakefile
is generated byconfigure
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It is no longer actively maintained, but has a lot of features and is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.
