#Netmap veth drivers#
Rtt min/avg/max/mdev = 0.052/0.052/0.052/0. Now all the netmap-provided drivers are available (e1000, e1000e, igb, ixgbe, i40e, veth, virtionet, forcedeth). #Packet sender container gets the ICMP echo reply ping 172.25.0.2 -c1 Uncover suspicious networks by accessing better data NetMap accesses broad claims data from ClaimSearch and uses sophisticated node link analysis and fraud analytics to find connections among massive amounts of data. #Decoder shows two ICMP packets - one for the echo request and other likely for the echoĭate: – 06:51:00 (uptime: 0d, 00h 07m 25s) – 06:43:40 - eth1: enabling zero copy mode by using data release call If you use GKEs CNI, one end of the Virtual Ethernet Device (veth) pair is attached to the Pod in its namespace, and the other is connected to the Linux.
– 06:43:40 - Using 8 AF_PACKET threads for interface eth1 First, I tested FdNetDevice with a pair of two virtual ethernet, peerd togheter: ip link add name veth0 type veth peer name veth1 ifconfig veth0. – 06:43:40 - 8 cores, so using 8 threads – 06:43:39 - Using defrag kernel functionality for AF_PACKET (iface eth1) – 06:43:39 - Using flow cluster mode for AF_PACKET (iface eth1) – 06:43:39 - Enabling tpacket v3 capture on iface eth1 – 06:43:39 - Enabling locked memory for mmap on iface eth1 – 06:43:35 - This is Suricata version 5.0.4 RELEASE running in SYSTEM mode
suricata.yaml -i eth1 -D -init-errors-fatal -vvv` by means of native support for Linux veth devices (over 40 Mpps). ICMP echo reply goes out of this interface.Īlso observed this same behavior with a veth-pair. The Netmap framework provides a simple and efficient user-space API for direct access. If I run Suricata on this same interface, my expectation was that Suricata will consume the ping request packet before it enters the Linux network stack, and hence I won’t see the ICMP echo reply. In absence of Suricata daemon, this ICMP ping request packet enters the Linux stack and ping response is generated and sent back on the same interface. The packet rx’ed on Suricata’s input interface is a ICMP echo request packet with destination address same as the one configured on that interface.
