This is to announce the availability of ntop packages for RedHat EL9 / RockyLinux 9 at packages.ntop.org. This has forced us to change many things in the way we build packages due to the deprecation of the SHA-1 algorithm. Because of this we had to modify the GPG signing keys used to sign the ntop […]
Welcome to ntopng 5.4: Enhanced Traffic Analysis and Cybersecurity

The level achieved made us think it justified even a major release. Welcome, n2n 3.0 ! Starting from this stable platform, future versions of n2n’s 3.x series will further […]
Introducing PF_RING ZC Support for Mellanox Adapters
PF_RING ZC is ntop’s high-speed zero-copy technology for high speed packet capture and processing. Until now ZC supported 10/40/100 Gbit adapters from Intel based on ASIC chips, in addition to the FPGA-based 100 Gbit adapters already supported by PF_RING including Accolade/Napatech/Silicom. This post is to announce a new ZC driver, known as mlx, supporting a new […]
