NETMAP ENABLE ZERO COPY WITH HOST STACK INSTALL
NETMAP ENABLE ZERO COPY WITH HOST STACK DRIVERS

Just went through the upgrade here and everything went fine. It means literally what it says - when your VLAN ID of 400 is tacked on to the package generated string for the interface PID filename, it results in a string longer than the 11-character limit. That particular error is being thrown by the Snort binary itself, I believe.

Suffix must less than 11 characters and not have '.' or '/' in the name.įirst question is was this a working install on the previous Snort version, or is this a new installation, or have you added this new VLAN interface recently?

Not all NIC drivers currently do this, but a few do. This is most efficiently done using the SID MGMT tab options.įor users on pfSense-2.5.0 DEVEL, the new Snort package includes support for multiple host rings when the physical NIC in the netmap connection pair exposes multiple rings. Inline IPS Mode lets you do that by selectively modifying the Action of rules you select from ALERT to DROP. The new Inline IPS Mode will be especially useful to security admins using the OpenAppID rules where you would like to drop selected traffic to a host, but not block all traffic from that host.

The new update will finally bring Inline IPS Mode using netmap to Snort on pfSense-2.4.5 systems! This is the same type of IPS operation currently available with Snort when using pfSense-2.5.0 DEVEL, and it's the same IPS mode available in the Suricata package.

However, the biggest change will be to users of Snort on pfSense-2.4.5 RELEASE. The updates include the latest Snort-2.9.16.1 binary from upstream. I've posted updates for the pfSense team to review and merge. Look for some changes in the Snort package in the near future.
