Suricata 4.0.0-rc1 ready for testing!

suri-400x400

We are proud to announce that the first release candidate for the upcoming Suricata 4.0.0 is ready for your testing. Since the beta1 release we’ve received much valuable feedback, leading to lots of fixed issues.

Notable changes: initial merge of Pierre Chiffliers Rust parsers work. This uses external Rust parser ‘crates’ and is enabled by using –enable-rust-experimental. This is even more experimental than –enable-rust, so use with care. Initially this adds a NTP parser.

The NFS parser adds support for catching up after packet loss, adds UDP support and basic NFSv2 support.

EVE was extended to optionally log the HTTP request and/or response bodies. Also new in EVE, the (partial) flow record is added to alert records.

We’re aiming for a final 4.0.0 release one month from now. If needed a rc2 release may be added to the schedule. Please help us test!
