Good
morning,
good
afternoon,
good
evening,
wherever
you're
hailing
from
welcome
to
another
episode
of
red
hat
enterprise,
linux
presents-
I
am
chris
short
host
of
with
the
most
of
all
things
red
hat
live
streaming.
I
am
joined
by
mr
redhat
enterprise,
linux
himself,
scott
and
eric
the
it
guy
there's
a
story
behind
that,
both
of
them
probably
but
welcome.
Narendev
back
to
the
channel.
I
haven't
seen
you
in
a
while
scott.
What
are
we
talking
about
today?
Buddy.
C
A
C
Yeah
yeah
and
to
be
fair
like
it,
it
wasn't
fully
baked
then
maybe,
and
it
was
a
big
departure
from
what
we
knew
and
loved
with
with
configuration
files
and
stuff.
But
we
closed
that
gap
significantly
in
seven
and
in
row.
Eight
network
manager
is
the
default
and
networking
is
still
distributed,
but
it's
deprecated
and
not
recommended
anymore
great.
C
Right
yeah
sure,
so
a
lot
of
people
probably
have
not
yet
noticed,
but
the
level
up
hour
has
changed.
Hosts
yes,
langdon
white,
unfortunately,
is
no
longer
with
red
hat,
he's
moved
to
pursue
a
career
in
academia,
and
so
I've
moved
over
there
to
be
one
of
three
hosts
on
the
level
up
hour,
and
because
of
that,
mr
eric
hendricks
is
going
to
be
taking
over
the
red
hat
enterprise.
Linux
presents
live
stream
with
elsinore
short.
B
D
Definitely
yeah
great
to
be
here.
Well,
I
guess
a
long
time
fan
first
time
caller,
ironically,
that
that's
the
the
chance
I
get
to
to
kind
of
try
and
follow
scott
and
kind
of
help
make
this
live
stream,
continue
to
provide
the
the
great
information
that
it
has.
So
I
am
a
technical
marketing
manager
here
at
red
hat,
I
work
with
scott
and
team
to
produce
a
lot
of
the
content.
D
D
I
used
to
run
arch
by
the
way
on
my
on
my
home
systems,
wow,
so
a
little
bit
of
everything,
linux
and
open
source,
and
then,
before
coming
to
red
hat,
I
actually
kicked
off
a
podcast.
It's
called
the
pseudo
show
quick
disclaimer.
It
has
no
nice
co2
keeping
an
eye
on
my
chin
on
the
chat,
quick
disclaimer.
The
pseudo
show
is
not
affiliated
with
red
hat,
but
glad
to
be
doing
that
show
as
well
as
this
one
to
to
talk
about
rel
so
glad
to
be
here.
B
A
C
D
I
want
to
play
the
krusty
sysadmin,
but
you
know
that's
fine
whatever,
so
with
network
manager,
it
allows
you
to
write
from
the
command
line,
make
all
the
changes
to
any
of
your
network
information
or
to
your
network
devices.
It
allows
you
to
pull
up
network
information,
so
you
can
see
link
status.
You
can
see
what
the
primary
protocol
is,
whether
that's
static
or
dhcp.
B
D
D
But
the
the
the
real
problem
with
the
iaf
config
files
is,
there
are
so
many
options.
Some
of
them
are
a
little
bit
obscure
some
of
them.
Don't
really
some
of
them
do
multiple
things,
so
it's
it.
It
can
be
kind
of
a
pain
to
try
and
keep
a
consistent
network
configuration
across
your
entire
enterprise.
D
D
A
C
Yeah,
I
will
tell
you
that
I
can't
speak
to
fedora,
because
definitely
I
don't
use
that
on
my
primary
box.
You
can't
edit
the
configuration
files,
even
though
they're
managed
by
network
manager,
and
it's
fine
like
you-
can
update
the
settings
in
there
and
network
manager
as
though
my
magic
picks
up
the
change,
because,
unlike.
C
I
know
right
so
in
the
in
the
olden
days
like
there
were
six
days
when
it
was
not
the
greatest
yeah.
What
ended
up
happening
was
we
stood
up
like
a
parallel
infrastructure
for
network
manager
under
completely
different
directory
and
had
its
own
files
actually
under
there
that
managed,
but
it
didn't
talk
to
the
other
files.
C
So
if
you
go
in
and
edit
the
files
it
gets
reflected
in
the
the
data
that
now
commander
has
access
to
as
well.
You
know
there
are
often
several
different
ways
to
do
things.
As
eric
pointed
out
like
sending
a
subnet
mask,
you
can
set
the
net
mask
or
you
can
set.
The
prefix
network
manager
knows
all
of
those,
and
so
all
the
stuff
that
was
documented
in
the
init
scripts
documentation,
which
is
what
was
the
holder
of
all
the
lexicon
of
rosetta
stone
for
those
settings.
C
You
know,
network
manager
does
all
that
plus
plus
plus
way
more
oh
yeah
yeah,
so
so
for
the
people
that
are
like,
I
like
editing
files,
you
could
still
edit
the
files,
I'm
not
stopping
you
from
editing
files.
Do
it
bye
be
aware
that
there's
more
that
you're
missing
by
editing
files,
if
that's
the
way
we're
doing
if
you
want
to
copy
files
to
other
boxes
and
that's
cool
too,
like
network
manager
will
be
able
to
hang
but
yeah.
C
A
C
All
right
so
one
of
the
other
tmns
on
my
and
eric's
team's
name's
jarrett.
He
wrote
this
networking
basics
lab
in
his
admin
101
series.
So
if
you're
interested
it's
on
lab.redhat.com,
I'm
sure
short,
we'll
paste
the
about
the
link
in
there
right
now
and
it's
about
using
nmcli.
But
before
we
do
that.
Just
pick
out
a
small
left.
A
C
D
C
D
B
C
C
C
C
C
D
A
A
C
B
D
C
B
C
C
B
D
D
C
All
right,
so
if
we
do
a
show
on
just
not
in
general
but
actually
on
an
individual
interface
or
connection,
as
the
case
may
be,
it
actually
shows
us
all
the
additional
settings
that
could
be
applied
to
this
interface,
which
in
the
past
to
eric's
point
very
early
in
the
show
right.
You
would
have
to
know
all
of
the
configuration
parameters
to
set
in
your
individual
file
ahead
of
time
in
order
to
utilize
them,
whereas
here
you're
showing
them
all
and
then
you
can
make
changes
with
nmcli.
D
C
B
A
D
D
B
So
for
my
cluster
here
at
home
right,
it's
all
sitting
on
one
dell
r820
in
the
basement,
and
it's
like
I
need
a
bridge.
I
need
multiple
interfaces,
it
was
all
done
through
cockpit
and
it
was
just
easy
as
it
could
be.
It's
like
you
want
a
bridge.
What
ip
do
you
want
it
to
have?
Oh
you
wanted
to
use
dhcp.
Okay,
that's
fine!
You
know
set
up
a
reservation
for
dhcp
and
the
network
devices
and
just
all
went
back.
C
D
C
You
could
do
the
10
steps
necessary
to
grow
your
lvm
file
system
through
the
command
line.
I
know
the
commands,
you
know
the
commands
we
can
do
that
or
you
can
go
into
the
web
console
highlight
the
thing.
Click
grow
file
system,
there's
a
slider,
so
you
can
grow
it
to
whatever
size
you
want,
as
opposed
to
being
like
wait.
How
big
is
it
again?
Oh
now,
I
need
to
go
back
out
and
like
look
at
the
command
to
see
how
much
space
is
left
in
the
device.
Oh
and
rounding.
D
D
C
A
A
A
B
C
A
C
C
D
D
Most
my
lab
itself
is
virtualized,
so
between
between
setting
up
all
the
virtual
machines
through
cockpit
and
doing
all
the
networking
it
was
so
nice
after
after
I,
I
was
one
of
those,
this
admins
who
would
who
would
grab
a
a
blog
post
off
the
internet.
That
worked
for
me
just
get
a
certain
thing
set
up
like
like
a
network
bond
and
I'd,
save
it
into
evernote
or.
D
D
And
then
I
went
to
set
up.
I
went
to
rebuild
my
lab
environment
just
a
few
months
ago
and
it's
like
cockpit
networking
bonds.
I
want
this
interface,
I
want
this
ip
range
activate,
sat
back
and
went
that's
going
to
break.
Isn't
it
a
few
seconds
later
the
the
cockpit
ui
refreshed
everything
worked.
I
was
like
well
I
just
I'm
just
gonna
log
out.
I
set
myself
like
two
hours
for
this.
It
took
two
minutes.
This
is
amazing.
I'm
just
going
to
go
to
sleep
so
there's.
C
C
B
C
And
if
you're,
coming
from
a
microsoft
background,
probably
teaming
is
more
similar
to
your
existing
experience
because
looks
really
similar.
The
configuration
settings
and
parameters
that
are
passed
is
very
familiar.
If
you're
coming
from
a
microsoft
background
on
making
network
interfaces
appear
as
one
and
then
they
also
have
some
additional
aggregation
modes.
If
I'm
remembering
in
teaming,
yes,
are
not
there
in
bonding,
so.
A
B
C
C
C
A
A
C
It's
not
a
small
class,
so
I
had
been
banging
away
at
it
for
a
while.
It
was
due
on
a
monday.
So
of
course,
I
had
worked
through
the
weekend
to
do
it,
because
I'm
terrible
at
planning
things
and
I
was
putting
together
the
final
pdf-
renders
that
I
could
upload
it
to
the
printer
on
monday,
like
the
print
shop
that
did
our
book
creation
friday
yeah.
C
C
C
But
yeah
so
so
I
ended
up
like
literally
staying
up
for
so
many
two
straight
hours
after
that
to
recreate
all
the
work
that
had
taken
me
a
prior
week
to
create
yeah,
but
so
what
I
learned
from
that
was
number
one:
don't
do
things
at
four
o'clock
in
the
morning
on
sunday
and
number:
two
wait
until
you
have
your
final
work
product
complete
before
you
do
anything
else.
Yes,.
B
A
B
D
All
right
I'll
share
mine,
there's,
there's
something
bad
about
just
working
when
you're
not
working.
I
there's
there's
a
theme
here
today,
because
there
was
a
time
I
was
working
as
a
sysadmin,
and
I
had
the
very
simple
task
of
we
want
some
archive
files
off
of
a
atlassian
hipchat
server,
because
hipchat
was
was
this
great
great,
instant
messaging
platform,
where
the
the
brilliant
idea
was
you
kind
of
had
to
reinstall
it
more
or
less.
That
was
the
upgrade
process
yeah.
Although.
D
Yeah
exactly
that
was
the
upgrade
process,
although
folks
got
kind
of
savvy
later
on
and
realized
that
I
could
just
clone
the
vm
do
the
upgrade
and
then
just
swing
to
the
new
vm
right.
So
we
did
that
and
then
someone
realized.
Oh
wait.
We
didn't
copy
all
the
archive
data
over.
So
let's
just
let's
just
power
up
the
old
vm
grab
those
files
drop
it
on
the
new
vm
and
you
know
no
big
deal
right.
It's
like
sure.
Well,
I'm
going
to
lunch
here
in
15.
A
D
We
we
got
to
leave
lunch
early,
that
day
came
back
to
the
office
and
go
figure.
I
needed
to
change
the
mac
address
on
the
old
vm,
because
we
didn't
want
any
interruption,
any
issues
with
the
load
balancer,
because
that
means
opening
a
ticket
with
the
networking
team
to
change
the
load
balancer.
So
we'll
just
we'll
keep
the
same
mac
address,
we'll
just
swing
it
over
to
the
new
vm.
No
problems
right!
D
Well,
brilliant
me
forgot
to
change
the
mac
address,
so
I
shut
it
down,
removed
the
networking
interface
completely
and
then
used
one
of
vmware's
tools
to
get
to
the
virtual
machine's
disk
said.
I
am
not
touching
this
thing
ever
again,
downloaded
it
to
my
desktop
uploaded
it
to
the
team
drive
and
just.
D
B
A
B
B
A
D
B
B
B
B
A
B
B
C
B
D
C
D
B
D
B
A
C
C
A
C
C
Figure
out
where
to
line
it
back
up
again
anyway,
so
I
have
these
punch
cards
that
are
punched,
which
also
is
somewhat
magical
and
around.
It
is
the
line
printed
program
that
was
written
for
the
cards
that
were
punched
for
it,
and
each
card
has
the
instruction
right
now
too,
but
it's
like
it's
it's
pretty
cool
and
many
years
ago.
C
Well,
actually,
not
that
many
years
ago,
a
long
time
ago,
I
wrote
something
for
training
and
much
to
my
sugar
in
it
was
production
for
17
years
and
the
reason
I
know
it's
production
for
17
years
is
because
on
year
17
they
came
to
me
and
they
were
like
hey.
We
need
you
to
make
a
change,
and
you
were
the
last
one
to
work
on
this,
and
I.
C
A
B
C
C
B
C
A
B
B
A
D
Coming
up
so
we've
got
a
we've,
got
a
few
different
ideas,
so
here
here
over
the
next
couple
months,
we
were
actually
looking
at
doing
kind
of
a
day
in
the
life
of
a
redhead
engineer.
So
we
talk
about.
We
talk
about
rel
all
the
time
we
talk
about
some
of
the
different
features
and
how
it
fits
into
the
industry.
So
we
thought
it
might
be
fun
to
bring
someone
in
from
engineering
to
kind
of
talk
about
what
what
do
you
do
every
day?
D
What's
you
know
just
just
a
day
in
the
life
we've
also
talked
about
building
building
system
d
unit
files,
and
then
a
little
known
fact
about
rel
eight
is
ntpd
is
not
the
the
default
anymore.
It's
crony
nowadays.
So
those
are.
These
are
some
topics
we're
considering
and
chris,
and
I
are
pretty
much
going
to
keep
the
show
format
exactly
how
it
has
been.
A
B
Because
it's
a
kernel
module
right
so-
and
this
is
from
you
know
a
case
person
so
like
kate,
cni
psyllium,
going
all
in
on
ebpf
is
something
that
they've
done
recently.
So
could
you
like
on
a
railbox
use?
Ebpf?
The
answer
is
yes,
anything
that
you
can
do
with
the
kernel
can
be
done
in
rel
and
ebpf.
I
mean
it's
incredibly
powerful.
It's
a
great
way
to
do
a
lot
with
network
policy,
and
you
know
firewalling
whatever
you
want
to
do.
C
So
we
typically
work
with
evpf
as
the
in
kernel
virtual
machine
for
performance
analytics,
so
there's
actually
in
the
bcc
tools.
There's
you
know:
tcp
latency
and
a
variety
of
other
networking
information
that
we
can
gather
from
the
eppf
virtual
machine
and
that's
typically,
where
I
see
it
used.
The
took
the
most
benefit.
B
A
C
A
A
A
B
B
You
know,
which
is
global
learning
services,
putting
the
three
of
them
together,
I
think,
will
create
a
powerhouse
show
for
the
level
of
power.
So
yeah
I
will
be
producing
other
shows.
But
yes,
I've
kind
of
handed
that
whole
show
kitten,
caboodle
off
minus
the
sweet,
sweet
internet
points
we'll
keep
those
going
as
long
as
the
team
wants
them
so
yeah.
So
eric
will
be
here
in
two
weeks
when
we
do
the
show
again
and
hopefully
we'll
have
something
cool
figured
out
for
you.
C
A
B
B
To
answer
your
question,
I
will
not
be
on
the
level
of
power
unless
they
ask
me
to
be,
but
red
hat
open
shift
is
always
watching
aka,
the
restream
account
so
yeah.
So
