Hi Fergus!!

Hello Fergus

or is it gangster of love?

F-F-Fritz

hey bud :)

But you can call me Maurice

Has role been called?

For some reason Rich's screen is hard to read. Anyone have that challenge? I wonder if I should change my resolution?

I love that question: What a terminal device really is: a place that has a name for you you read things from it and write things to it

I can see everything correctly

username = first 3 letters of lastname + 3 letters first name+90

IT != psychic

the CTC server room is very quite too

quiet

Is it too late to send a mugshot?

if you forget the username for an account you need to SU into you can look in the /etc/passwd file

thanks. concatenate. the verb "cat-out" was new to me.

can't view shadow

that helps

Can we see who is trying to brute force us personally? like on our own wifi router? at comcast or wherever?

is there a way to check that on the opus-ii server? if so is there a command to check that?

I have that question too Chris!

must be cat /var/log/wtmp

like is on the slide

the "lastb" command does not give me the permission

ah ok tx

Im denied

yeah

we are in the wrong directory proably

I tried cat /var/log/wtmp and I got a screen full of putty that I had to control c out of

me too haha

what was your path?

type pwd

lab due tonight? from last week? I thought it was due last night before midnight?

ok so you were in the ~ direcotry

tonight

six random words will be guessable if someone knows you well perhaps - like the 20 questions game- you know a bit what your friends are thinking of or associating to

then pick random words--use a random number generator to pick pages and lines of the dictionary, or something like that

budget audit: why does cabrillo need a titan xp? because ethical hacking lab

what is a titan xp

Would you use a GPU for cracking?

this is like passing notes during class

yeah gpu hashing

That's more of a CPU thing, right?

We host space for other schools

Oh, yeah.

I asked rich that last week

yes, you would use a gpu

And the server space is rented out to other schools

thanks professor you just answered my question about lab 1. I thought labs were due on Tuesdays before midnight.

do you use 'ntpdate time.nist.gov' ?

@rich is verify local only to your server?

after we finish this class do our opus accounts get deleted ?

hit the SUBSCriBE button

does setting up a homelab with msserver that is also hosating stuff for me count as "educational use"

oh bother, how do we join the group on linkedin?

my local host won't work

localhost is a system name (hostname) not a user name

༼ つ ◕_◕ ༽つ

Why is it clipping off the "e"

is that universal?

or is that local to the server?

my debain server doesent have banner and its unable to locate a package for it

so will most types be located in the main intstallation folder?

so what do we need to memorize - how to learn these commands?

you will probaly memorize the ones you use alot

The goal is to have a small queue size, which is good for inter‐activity while not disturbing TCP/IP traffic with too many suddendrops after a burst of traffic.Depending on if ECN is configured, marking either means droppingor purely marking a packet as overlimit.

why not just use PWD

pwd?

Which paths have priority?

is it possible to corrupt them?

echo is built in

how do i draw

can't get my annotation lines to work must have missed something in lecture

༼ つ ◕_◕ ༽つ

To draw, you need to go to the options at the top of the window and click on 'anotate', but it's only available when Rich enables it
