At the time of this writing, I could not find a Docker container for ntopng community edition. The install guide seem to be pretty easy, but I encountered an issue where I could not install these packages pfring-dkms, n2disk, nprobe, ntopng and cento. I just want to share how I got this working.
Update the CentOS 8 LXC and install tmux, vim, and openssh-server.
yum update -y yum install -y epel-release yum install -y tmux vim openssh-server
Start and enable the
sshd to allow us to SSH-in to the container.
systemctl start sshd systemctl enable sshd
SSH-in to the CentOS LXC then execute the
tmux, so that just in case we get disconnected we can continue our session by using the
tmux attach command.
Navigate to the
/etc/yum.repos.d/ and download the
ntop.repo. Once done, install the latest epel-release for CentOS 8 via
cd /etc/yum.repos.d/ wget http://packages.ntop.org/centos-stable/ntop.repo -O ntop.repo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
Installing what is needed for ntop will take awhile, I would suggest to use
tmux as mentioned earlier.
yum erase zeromq3 yum clean all yum install -y pfring-dkms n2disk nprobe ntopng cento
Once the installation is complete, start the ntopng service and enable the ntopng service.
systemctl start ntopng systemctl enable ntopng
This is optional. See it here: https://www.ntop.org/products/packet-capture/pf_ring/pf_ring-zc-zero-copy/
yum install -y pfring-drivers-zc-dkms
At this point, navigate to the web UI via http://<ip-address>:3000.
- Login with admin/admin as shown in Figure 1
- The next page will prompt your to change the admin password
Hope you’ll find this usefull. Cheers!
This manual was very usefull! Except one missing part:
Yes, this is true with bare-metal and VM install. However, I was using LXC container and firewalld is not part of the LXC package. I guess for those who are going to be reading this in the future and wanting to use firewalld on an LXC container.
dnf install firewalld
Then follow the comment above to allow the web UI port.
