I’m not a huge Video guy. I mean I have a lot of videos but I’m not really a
“Video expert” If that makes any sense. I’m an expert “Watching” videos :)

Although I do know a thing or two about it. “How to get to watch them” I use
ffmpeg a lot because I like to do stuff from the command line.
ffmpeg fits the bill https://ffmpeg.org/

I use it for converting / combining / etcetra….

Small script below that I use for combining videos.

timc@sc2:~$ cat concat.sh
ECHO="/usr/bin/echo"
FFMPEG="/usr/bin/ffmpeg"

$ECHO " ========================================================="
$FFMPEG -f concat -safe 0 -i ./concat.txt -c copy output.mp4
$ECHO "========================================================="
exit
timc@sc2:~$ 

Where concat.txt is as follows. These are the two files I want to combine

timc@sc2:~$ cat concat.txt 
#file './Moby.Dick.Part.1.1998.480p.AMZN.WEB-DL.DDP2.0.H.264-playWEB.mkv'
#file './Moby.Dick.Part.2.1998.480p.AMZN.WEB-DL.DDP2.0.H.264-playWEB.mkv'
file './Les.Vampires.1915.Part.1.mkv'
file './Les.Vampires.1915.Part.2.mkv'
timc@sc2:~$ 

and the file output.mp4 is a combination of the two files above. It works it’s way
through the files giving me any issues it sees and if audio is off and by how much
as well as stream issues.

Really cool free program. These guys rock. I’m planning to donate to them at some
point, but haven’t yet. Highly recommend that program for working with video from
the command line

How many movies do I have?
What years are they from?
Resolution?
Type of encoding?
HEHEHE.

I have a openvpn tunnel up normally for certain things and want to kill some processes
if the tunnel goes down…

Check every minute

* * * * * /root/bin/tun.up.sh >> /var/log/tunnel.up.log

Which checks for the tunnel tun0 and kill some processes if it’s not.

IFCONFIG=/sbin/ifconfig
GREP=/usr/bin/grep
ECHO=/usr/bin/echo
AWK=/usr/bin/awk
PS=/usr/bin/ps
PKILL=/usr/bin/pkill
DATE=`/usr/bin/date +"%m.%d.%y.%H.%M"`
PGREP=/usr/bin/pgrep

TEST=`$IFCONFIG | $GREP tun | $AWK '{print $1}'`
TOKILL=`$PS | $GREP ktorrent`

if [ $TEST == "tun0:" ]; then
 $ECHO $TEST " UP " $DATE
 exit
fi

PROC=`$PGREP ktorrent`
#$ECHO "Killing " $PROC
$ECHO $TEST " DOWN " $DATE
$PKILL -f ktorrent

Going to write a bit more code in the near future to bring the tunnel back up when it goes down
but that’s something for a different day.

Gotta Schedule it with crontab -e (I use joe a wordstar equivalent)

My recent review of the latest IETF NGFW performance testing Draft for RFC:

I think these guys are way off base with no grasp of reality. If you just want a raw
number of what a firewall can do without any real world issues, then MAYBE it’ll work
although I would argue that point…

I also, wanted to chime in regarding this and again, I also apologize for not reviewing earlier.

I’ve not really been too involved in security devices until the last couple years, but boy has it changed
drastically from when I was. Also, I noted that this document is basically following prior standards that
are also a bit out dated.

Some of the evolution, I’ve noticed which I think should at least be addressed in. I think you tried
to exclude these in the Scope.? However I’m not really sure you are covering but maybe 1/2 of the devices
that are being deployed at this time without addressing:

Virtualization. / Remote FWs in the next gen.

*) Large FWs are compartmentalizing Customers and serving multiple customers with the same firewall. So while
you have said what would happen to a customer when The Firewall is UT, you don’t really address what’s going
on with all the other customers on this DUT. If there are 10 Customers going through 1 large FW, what are the
other 9 experiencing when this is under Test. Would be interesting to have multiple parallel tests underway
and verify that behaviour is consistent across every “VDOM” within the system?

*) Time to Change. If things are changed during your Load profile.perhaps even on a different virtual Firewall
within the system,

*) Sandbox dips. Several of the firewall vendors send stuff through labs / temp work spaces either online or
offline that allow them to test against Zero Day scenarios. What happens to traffic flows during anomalies
in the traffic flows. Does it change the throughput of the DUT? I know this is kind of an open ended question.
but not sure you have good benchmark stats for a FW without it…

*) Cloud based scenarios. If the firewall is removed, and I’m not really sure how you would test this with
consistent results, but if the FW is offsite and the traffic is being routed through a Cloud based FW What does
that do to your traffic results?
