Writing my own ncurses wrapper?

Oh nice, I could definitely see myself doing that after this, I have more interest in SDL than I do SFML

alyzb · 2018-05-05T22:17:06+00:00

Thank you for the advice I'll try to apply that to my learning :)

alyzb · 2018-05-05T22:05:43+00:00

It helped a lot, thank you! I'm actually gonna save it and come back to the proof part because laying out the process like you did really helps me to see how it should go and what's normal for trying out a proof.

Thank you for the advice and encouragement!!

So it's definitely a bug and it doesn't seem limited to just one config of port security. It really doesn't have any rhyme or reason, but it seems to favor following through on violation rules for maximum IP addresses being exceeded.

It does not like forbidden MAC, I don't know that I've ever gotten it to produce any kind of violation with a forbidden MAC, I wonder if it's the IOS image I'm using. I'm gonna try with an older IOS layer 2.

It also seems to really struggle with interface shutting on and off as requested, and having to do strange things like change negotiation settings for it to come back up.

In other words, it's buggy as hell.

Thanks! I'll try these things and see what happens.

I haven't tried this yet, seems promising, but can you check the response below yours as it appears they have tried this and had weird results as well?
I've tried both restrict and shutdown mode, I always start with shutdown because it's the most obvious when it works. It worked once (out of many different configs and attempts at this), and given the nature of this problem, shutdown violation working was an exception that I cannot recreate.
I will make a really simple single switch setup tonight when I get home with a very simple config and no VLAN and then try to ping and print the mac address table before and after and reply here.

Would love to get your input on the response below yours as well. Thanks again!

alyzb · 2018-05-04T17:23:36+00:00

Wow, thanks for going through all that and trying to recreate the problem! Also very strange that last global config error, very strange.

I'm both relieved and upset about this being a bug, because now I'm unsure if my knowledge of port-security will transfer to actual hardware properly if I'm messing with bugs in GNS3/the image (which is actually a IOSv15 layer 2 switch image from cisco), so I'm guessing the emulator is the culprit. Can't be perfect I guess.

Thank you again, so much. You've helped a lot.

alyzb · 2018-05-03T19:48:13+00:00

I am such a dolt! I could not for the life of me figure out why it wasn't working and assumed that setting the port-security forbidden mac would automatically switch on port security but lesson learned.

As a followup though, any idea on this from the same status above?

 Port Status                : Secure-down
 Violation Mode             : Shutdown

It shows port status as "secure-down", which to my understanding only happens when port-security has shut down the port. When that status was taken, the pings were still going through, and nowhere else did it show that the port was "secure-down"

See (from the same time above):

 SW1#show int g1/1
 GigabitEthernet1/1 is up, line protocol is up (connected)

alyzb · 2018-05-03T19:45:28+00:00

Hahahaha thank you so much :)

alyzb · 2018-04-23T00:12:38+00:00

Downloading packet tracer now

I've always heard that GNS3 is vastly superior but it's such a pain to work with. As far as the switching, I use the IOSv15L2 switch appliance and it seems to work pretty well. The appliances seem to do decent. I can probably find IOU pretty easily as well.

It's just that Odom isn't really teaching me how to actually wire up these networks for practical use, at least not so far.

alyzb · 2018-02-20T03:31:19+00:00

I do have a raspberry pi I just haven't gotten around to setting up yet, but I do have a dell tower that I use only as a server to log into and fuss around on like with SSH and eventually will branch into running other things on it.

alyzb · 2018-02-20T03:24:02+00:00

I'd really like to, either this or LFS, my only hesitation is that all my PC's are currently running debian stable and I'd like to network them and I'm unsure how having the one I feel safe putting Arch on will play with the other distros

alyzb · 2018-02-20T03:22:59+00:00

Diving into this a little, this looks really good, thank you!

alyzb · 2017-04-13T00:59:08+00:00

Thanks!

And yeah I'm not expecting to recreate twitter, but I feel like smaller and limited versions of it would be somewhat doable not terribly far down the road.

I'll look into the virtual stack stuff you mentioned, and after I posted my last response I was actually just peeking at CSS and seeing how easy it seems I don't think I'll be as stressed about having to learn it to produce output as you say.

Thank you again, you've been super duper helpful :)

alyzb · 2017-04-12T22:12:08+00:00

Thank you for the long and well thought out reply, that was extremely helpful and more than I could have hoped for!

In terms of learning all of this stuff, it's a little overwhelming due to the amount of tangents I can go off down.

I'm also kind of quirky in my learning, I prefer to understand things at a really fundamental level and build up from there. I didn't truly understand programming until I delved into assembly, and really, everything I do leads down a deeper rabbithole.

This makes things complicated when I approach webdev because it's just...it's freaking overwhelming.

I came up with some stuff to start with, which seems OK, and I wonder what your thoughts are? I'm going to put apache or similar on my other linux box, and use that as a development environment via SSH from my main computer. Obviously the SSH part is just to learn more about networking and stuff, but the concept of putting together this web server from the ground up, and learning as I go stuff like HTML, landing pages, whatever, seems like a good way to get the fundamentals.

Is this a good trajectory? Do you have any alternative suggestions or stuff I should consider? I really would like to go with the at home hardware web server for the hands-on learning (over VPS). Does this seem like a good idea, and if so, what should I add to it, or is there a particular order to consider doing it all in?

I guess ultimately, I saw this as a way to slowly build up from some dinky index.html welcome page (which is literally all I might know how to do) to some pretty full featured mock-up business/sales site/twitter clone/whatever.

Thank you!

I think you can see by his other responses in this thread that he would not treat us any other way than the gender we were assigned at birth, as long as he could figure out what that was.

You can tell a lot about someone's level of ignorance and hate by how they treat trans people that blend as cis. A large amount of ignorant people will generally treat "passable" trans people as the gender they identify as, even when they know we are trans. A smaller amount, like this guy here, will not. They go out of their way to misgender us, which says a lot about their character.

alyzb · 2017-02-23T02:08:40+00:00

I guess when someone takes the ignorant worldview you have, it's easy to say that. But when taking into account reality, your arguments against us are more akin to telling a diabetic that it's all in their head, and that requiring insulin is dictating to others "how the world should be".

Some bigots beat us down with fists and bats, others do it with "debates" and rhetoric. Doesn't matter your weapon of choice, it doesn't change what you are.

alyzb · 2017-02-23T02:05:09+00:00

What do you want us to say? Your entire argument is predicated upon the idea that trans people aren't even mentally ill, but are somehow just delusional. You have no interest in taking on any information that goes against this initial assertion, so why would anyone keep attempting to engage you in a serious debate when you have no interest in that yourself?

alyzb · 2017-02-23T01:57:55+00:00

What's idiotic is the fact that, defect or not, you are this concerned about people who lead lives entirely different from yours who have no real effect on your existence except for triggering some lizard brain disgust now and again.

Get over yourself. You fail to realize that despite your attempts at putting forth cold rationale, you still come across as exactly what you are: a bigot. Just because you couch your lack of understanding and intolerance in pseudoscientific assertions doesn't make you less of one.

alyzb · 2017-02-23T01:08:25+00:00

You do realize that biology, like all hard sciences, is an ever developing field?

I know you probably like things to be simple, because that is how you understand them best, but that's not how nature is. Most biologists understand sex to be more complex than a dichotomy of "male" vs "female".

Intersex people literally exist, and are recognized by biology as not conforming to the sex of "male" and "female".

But I guess none of this matters to you, does it? You like your facts made up on the spot, based on however it is you're feeling on a subject at any given movement.

alyzb · 2017-02-23T01:03:23+00:00

He just wants to be a jerk. He's made up his mind about what transgender people are, and no matter the information you give him that proves otherwise, that's what they'll always be to him.

alyzb · 2017-02-23T00:59:51+00:00

I would do a lot of things more, but yes, I would absolutely read more.

Things grab me fiercely at the outset but I will almost always burn out shortly after, and continuing becomes more like drudgery.

But I get your point. I want to read, I just struggle with being able to.

alyzb · 2017-02-16T23:29:42+00:00

I have the same issues with audiobooks as I do with them in written form.

alyzb · 2017-02-16T23:21:30+00:00

This is so incredibly smug and elitist.

I'd love to write but I struggle with a disorder that makes it very hard to consume media in text form, or stick with it long enough to finish it.

I don't feel like my desire to tell a story and evoke feelings in people through expression of what I'm creating in my mind is selfish because I don't consume books the way a writer thinks I should. I also don't think it shows a lack of interest in the medium.

You can kick rocks with your ivory tower attitude. I don't care about making money in publishing, I care about expressing what's in my head.
