RPMs and Yum Repository

We provide selected releases of our tools as RPM packages, both via a Yum repository and as direct downloads. We currently build for the following distributions:

• Red Hat Enterprise Linux 10 (since May 2026)
• Red Hat Enterprise Linux 9
• Red Hat Enterprise Linux 8

We build RPM packages for the following software packages, with some default configuration:

• fixbuf-tools since 4.0.1 (RHEL10 since 4.0.4)
• libfixbuf since 2.5.1 (with OpenSSL support enabled) (RHEL10 since 2.5.4)
• SiLK since 3.23.2 (with IPv6, GnuTLS, fixbuf, PySiLK, Snappy, and MaxMind (since 3.23.4) support enabled) (RHEL10 since 3.24.2)
• super_mediator since 1.11.2 (with SiLK support enabled) (RHEL10 since 1.13.2)
• YAF since 2.16.2 (with applabel, plugins, OpenSSL, and zlib support enabled) (RHEL10 since 2.17.6)

Yum Repository

The easiest way to use the NetSA Tools Yum repository is to install the appropriate repository RPM:

# Install the repository RPM for RHEL8:
sudo dnf install -y \
  https://tools.netsa.cert.org/yum/reporpms/netsa-tools-repo-2025.1-1.el8.noarch.rpm

# Install the repository RPM for RHEL9:
sudo dnf install -y \
  https://tools.netsa.cert.org/yum/reporpms/netsa-tools-repo-2025.1-1.el9.noarch.rpm

# Install the repository RPM for RHEL10:
sudo dnf install -y \
  https://tools.netsa.cert.org/yum/reporpms/netsa-tools-repo-2026.2-1.el10.noarch.rpm

Installing these repository RPMs will add the NetSA GPG signing key to your system, and the NetSA Tools Yum repository to your Yum repos. You can then install individual packages like:

# Install fixbuf IFPIX tools, SiLK analysis tools, rwflowpack, and YAF:
sudo dnf install -y fixbuf-tools silk-analysis silk-rwflowpack yaf

Direct RPM download

If you can't use the yum-based installation method or would prefer not to use it, you may access all of the RPMs directly from the Yum repository.
