Multiple interfaces on the same machine

Nuno_Santos · November 29, 2020, 9:11pm

Hi there. I have implemented a suricata solution in one interface. That interface is a mirrored WAN port. So all the traffic that i see is to the internet.

I want to monitor my internal traffic as well. Is it possible to add another interface on the suricata.yaml?

Andreas_Herz · November 29, 2020, 9:25pm

yes, you can write a second interface section like this:

af-packet:
  - interface: eth0
   <snip options>
   -interface: eth1

Nuno_Santos · November 29, 2020, 9:51pm

Thanks. Imagining if the new interface is a mirred trunk port with all my VLANs.

Do i have to do something special or just define my networks on the yaml?

Andreas_Herz · December 27, 2020, 8:59pm

Just define the network in the yaml in the HOME_NET section, you might want to check the vlan use-for-tracking option and set it to yes.

Hello,

I need to implement two interfaces (bond0 and bond1).

RHEL 8.4
Suricata 6.0.3

I need to edit two files (/etc/sysconfig/suricata and/etc/suricata/suricata.yaml).

In “/etc/sysconfig/suricata” I have:
OPTIONS = “- i bond0 -i bond1”

In “/etc/suricata/suricata.yaml” I have:

# Linux high speed capture support
af-packet:
  - interface: bond0
  - interface: bond1
    # Number of receive threads. "auto" uses the number of cores
    #threads: auto
    # Default clusterid. AF_PACKET will load balance packets based on flow.
    cluster-id: 99
    # Default AF_PACKET cluster type. AF_PACKET can load balance per flow or per hash.
    # This is only supported for Linux kernel > 3.1
    # possible value are:
    #  * cluster_flow: all packets of a given flow are sent to the same socket
    #  * cluster_cpu: all packets treated in kernel by a CPU are sent to the same socket
    #  * cluster_qm: all packets linked by network card to a RSS queue are sent to the same
    #  socket. Requires at least Linux 3.14.
    #  * cluster_ebpf: eBPF file load balancing. See doc/userguide/capture-hardware/ebpf-xdp.rst for
    #  more info.
    # Recommended modes are cluster_flow on most boxes and cluster_cpu or cluster_qm on system
    # with capture card using RSS (requires cpu affinity tuning and system IRQ tuning)
    cluster-type: cluster_flow
    # In some fragmentation cases, the hash can not be computed. If "defrag" is set
    # to yes, the kernel will do the needed defragmentation before sending the packets.
    defrag: yes
    # To use the ring feature of AF_PACKET, set 'use-mmap' to yes
    use-mmap: yes
    # Lock memory map to avoid it being swapped. Be careful that over
    # subscribing could lock your system
    #mmap-locked: yes
    # Use tpacket_v3 capture mode, only active if use-mmap is true
    # Don't use it in IPS or TAP mode as it causes severe latency
    tpacket-v3: yes
    # Ring size will be computed with respect to "max-pending-packets" and number
    # of threads. You can set manually the ring size in number of packets by setting
    # the following value. If you are using flow "cluster-type" and have really network
    # intensive single-flow you may want to set the "ring-size" independently of the number
    # of threads:
    #ring-size: 2048
    # Block size is used by tpacket_v3 only. It should set to a value high enough to contain
    # a decent number of packets. Size is in bytes so please consider your MTU. It should be
    # a power of 2 and it must be multiple of page size (usually 4096).
    #block-size: 32768
    # tpacket_v3 block timeout: an open block is passed to userspace if it is not
    # filled after block-timeout milliseconds.
    #block-timeout: 10
    # On busy systems, set it to yes to help recover from a packet drop
    # phase. This will result in some packets (at max a ring flush) not being inspected.
    #use-emergency-flush: yes
    # recv buffer size, increased value could improve performance
    # buffer-size: 32768
    # Set to yes to disable promiscuous mode
    # disable-promisc: no
    # Choose checksum verification mode for the interface. At the moment
    # of the capture, some packets may have an invalid checksum due to
    # the checksum computation being offloaded to the network card.
    # Possible values are:
    #  - kernel: use indication sent by kernel for each packet (default)
    #  - yes: checksum validation is forced
    #  - no: checksum validation is disabled
    #  - auto: Suricata uses a statistical approach to detect when
    #  checksum off-loading is used.
    # Warning: 'capture.checksum-validation' must be set to yes to have any validation
    #checksum-checks: kernel
    # BPF filter to apply to this interface. The pcap filter syntax applies here.
    #bpf-filter: port 80 or udp
    # You can use the following variables to activate AF_PACKET tap or IPS mode.
    # If copy-mode is set to ips or tap, the traffic coming to the current
    # interface will be copied to the copy-iface interface. If 'tap' is set, the
    # copy is complete. If 'ips' is set, the packet matching a 'drop' action
    # will not be copied.
    #copy-mode: ips
    #copy-iface: eth1
    #  For eBPF and XDP setup including bypass, filter and load balancing, please
    #  see doc/userguide/capture-hardware/ebpf-xdp.rst for more info.

  # Put default values here. These will be used for an interface that is not
  # in the list above.
  - interface: default
    #threads: auto
    use-mmap: yes
    tpacket-v3: yes

It is right?

Thank you for your help

Michael

Change /etc/sysconfig/suricata – the option you want is --af-packet

The suricata.yaml file should change. Each interface should have it’s own options; minimally, the cluster-id should be unique for each interface.

This example is from our documentation at suricata.readthedocs.io You can use defaults for most of the options but make sure cluster-id is unique for all interfaces; you can comment out (or remove) the items you don’t need.

- interface: eth1
  # Number of receive threads. "auto" uses the number of cores
  threads: 18
  cluster-id: 99
  cluster-type: cluster_qm
  defrag: no
  use-mmap: yes
  mmap-locked: yes
  tpacket-v3: yes
  ring-size: 100000
  block-size: 1048576
- interface: eth1
  # Number of receive threads. "auto" uses the number of cores
  threads: 18
  cluster-id: 99
  cluster-type: cluster_qm
  defrag: no
  use-mmap: yes
  mmap-locked: yes
  tpacket-v3: yes
  ring-size: 100000
  block-size: 1048576

Hello Jeff and Team!

Is there anyway of confirming what interfaces Suricata is listening on?

I also have a bonded interface on Ubuntu 20.0.04 composing of two interfaces and therefore have my configuration such as:

af-packet:
  - interface: bond0
   <snip options>
   cluster-id: 99
   -interface: eno1np0
   <snip options>
   cluster-id: 98
   -interface: eno1np0
   <snip options>
   cluster-id: 97

Where <snip options> have the same defaults for all interfaces apart from a unique cluster-id.

Thanks for your help in advance! TYIA!

Andreas_Herz · October 19, 2022, 7:43am

You can check the output of the suricata.log and also use suricatasc to get interface specific stats with iface-stat bond0 and so on.

ADudeWhoSurfs · October 19, 2022, 3:43pm

Thanks so much @Andreas_Herz !

I read up the docs about this Python script and followed pre-requisites via:

https://manpages.ubuntu.com/manpages/bionic/man1/suricatasc.1.html
https://suricata.readthedocs.io/en/suricata-6.0.0/unix-socket.html

Ensuring I had python-simplejson installed etc.

I also changed my /etc/suricata.suricata.yaml config from “AUTO” to “YES” and again restarted Suricata process.

# Unix command socket that can be used to pass commands to Suricata.
# An external tool can then connect to get information from Suricata
# or trigger some modifications of the engine. Set enabled to yes
# to activate the feature. In auto mode, the feature will only be
# activated in live capture mode. You can use the filename variable to set
# the file name of the socket.
unix-command:
  enabled: yes
  #filename: custom.socket

srw-rw---- 1 root root 0 Oct 19 15:33 /var/run/suricata/suricata-command.socket

When I try to invoke the Python script, I always yield the error:

# sudo suricatasc /var/run/suricata/suricata-command.socket
Unable to connect to socket /var/run/suricata/suricata-command.socket: [Errno 111] Connection refused

If I run systemctl status suricata, I do not see any mention of Unix socket and not sure if this is related.

Am I missing something here? Apologies in advance if so.

In the meantime, I will have a look through /var/log/suricata/suricata.log for any related information about interface statistics which is a hefty file

Andreas_Herz · October 19, 2022, 3:53pm

The config option etc. look correct. So hard to tell why the connection is refused, is there anything in the log related to that?

Also paste suricata --build-info an in general how did you install suricata?

I followed the docs at * Installation guides for Ubuntu.

I have a very similar setup on a different server on "Ubuntu 20.04.4 LTS" and sudo suricatasc /var/run/suricata/suricata-command.socket works with no issues.

Nothing in the /var/log/suricata/suricata.log either

Update:
Apologies, forgot to mention I used this reference for deployment as an initial guide:

Do I need to amend some config somewhere? This does seem to be related IMO
It doesn’t seem to be supporting/picking up multiple interfaces from the config file by looking at the logs.

OR, does the format need to be like in the config file: (separating the - interface with af-packet segment?)

**af-packet:**
  - interface: bond0
   <snip options>
   cluster-id: 99
**af-packet:**
   -interface: eno1np0
   <snip options>
   cluster-id: 98
**af-packet:**
   -interface: eno1np0
   <snip options>
   cluster-id: 97

TYIA!

Please accept my sincere apologies, please ignore my portion of above comment relating to tertiary-defined interface eno2np0… this was an extremely dumb typo of the interface eno2np1 and is no longer an issue.

Hello,
Apologies, but I managed to remediate the issue!

# Linux high speed capture support

  - interface: bond0

I allocated (as per example config above) 20 cores to each interface (3 x 30 = 60 out of 80) as it looks like they were overlapping and causing the issue

This has also fixed suricatasc, thanks for all your help!!
