R80.20 - new interesting commands

[HeikoAnkenbrand]

I've been testing R80.20 very intensively in the lab over the last few days. Here I have discovered some interesting new commands on CLI. What did you discover that didn't exist before?

# cphaprob stat     > with more clusterxl informations

# fwaccel ranges   > show's anti spoofing ranges

# fw ctl multik utilize   > shows the CoreXL queue utilization for each CoreXL FW instance

# fw ctl multik print_heavy_conn   > shows the table with heavy connections

More see:

Command Line Interface R80.20 Reference Guide

# cphaprob stat

Exciting command show's anti spoofing ranges:-)

You have to take a closer look.

# fwaccel ranges

Heiko

[HeikoAnkenbrand]

Shows the CoreXL queue utilization for each CoreXL FW instance

# fw ctl multik utilize

[Yoni-Indeni]

Have you ever seen the queue fill up? Is this something worth tracking and adding a script to Indeni for?

[HeikoAnkenbrand]

Shows the table with Heavy Connections (that consume the most CPU resources) in the CoreXL

Dynamic Dispatcher.

# fw ctl multik print_heavy_conn

[Ofir_Shikolski]

fw ctl multik stop / start

The blacklist blocks all traffic to and from the specified IP addresses.

The blacklist drops occur in SecureXL, which is more efficient than an Access Control Policy to drop the packets.

This can be very helpful e.g. with DoS attacks to block an IP on SecureXL level.

# fwaccel dos blacklist -a <ip>

# fwaccel dos blacklist -s

# fwaccel dos blacklist -d <ip>

This looks a lot like #sim dropcfg which has the same functionality.

edit:

Off course its handy to have a link to more information of this useful feature

See Accelerated Drops which is supported since 75.40

# fw ctl chain

The new fw monitor chain modules (SecureXL) do not run in the virtual machine (vm):

SecureXL inbound (sxl_in)                    > Packet received in SecureXL from network

SecureXL inbound CT (sxl_ct)              > Accelerated packets moved from inbound to outbound processing (post routing)

SecureXL outbound (sxl_out)               > Accelerated packet starts outbound processing

SecureXL deliver (sxl_deliver)             > SecureXL transmits accelerated packet

[HeikoAnkenbrand]

There are more new chain modules in R80.20:

vpn before offload (vpn_in)                  > FW inbound preparing the tunnel for offloading the packet (along with the connection)

fw offload inbound (offload_in)            > FW inbound that perform the offload

fw post VM inbound  (post_vm)            > Packet was not offloaded (slow path) - continue processing in FW inbound

[HeikoAnkenbrand]

More see here:

R80.20 SecureXL + new chain modules + fw monitor 

[HeikoAnkenbrand]

In firewall kernel (now also SecureXL), each kernel is associated with a key (blue) witch specifies the type of traffic applicable to the chain modul.

# fw ctl chain

# fw monitor -e ...

Key	Function
ffffffff	IP Option Stip/Restore
00000001	new processed flows
00000002	wire mode
00000003	will applied to all ciphered traffic (VPN)
00000000	SecureXL offloading (new in R80.20+)

Fetches and unloads Threat Prevention policy.

Threat Prevention policy applies to these Software Blades:

• Anti-Bot
• Anti-Virus
• Anti-Spam
• Threat Emulation
• Threat Extraction
• IPS

# fw amw unload                    -> To unload the current Threat Prevention policy.

# fw amw fetch localhost      -> To fetch the Threat Prevention policy stored locally on the Security Gateway.

"iotop" watches I/O usage information output by the Linux kernel  and displays a table of current I/O usage by processes or threads on the system. Only available on gateway with R80.20 3.10 kernel (see Check Point R80.20 with Gaia 3.10 for Security Gateways).

# iotop -b -n 1

great job
