JICMP is a small library to allow the use of IPv4 ICMP (raw) packets in Java.
Requirements:
- git
- automake
- autoconf
- libtool
- Java JDK 1.8+
The repository has a git submodule which contains Macros required to compile from source code.
Clone the respository on local disk
git clone https://github.com/OpenNMS/jicmp.git
Switch into source code repository
cd jicmp
Initialize and update the git submodule.
git submodule update --init --recursive
Update generated configuration files with
autoreconf -fvi
Generate make files using /usr/local/lib
as install path and compile JICMP
./configure
make
Tip
If you want to change the install path the ./configure --prefix=/your/custom/path
can be used.
Install the library on your system, root permissions may required when working as non-root user.
sudo make install
Mac OS X supports non-root ICMP through the $$SOCK_DGRAM$$ interface, which JICMP uses by default.
Linux supports this as well, but you additionally need to set a sysctl OID to allow ping for non-root users.
You can set this temporarily by running:
sysctl -w net.ipv4.ping_group_range="0 429496729"
... or by creating a sysctl
configuration file in /etc
:
echo "net.ipv4.ping_group_range=0 429496729" > /etc/sysctl.d/03-non-root-icmp.conf
