Q: One line command in windows to get computer's wifi address

I have a windows server setup where I would like to get the wifi address of server dynamically. The problem is that ipconfig returns a huge string and the script I am using wants the address straightaway. Is there any command to get this straightaway? I am open to the idea of an external .bat sc...

command-line ip

wifi address?

JohnMerlino

00:52

why would a computer require two network cards?

A single nic contains a unique mac address which suffices to communicate over a network. So why would a computer need another network card?

Michael Frank

redundancy, or for use as a hardware firewall

JohnMerlino

redundancy? Something like RAID?

Journeyman Geek

@JohnMerlino: with some setups, you can use both together.

or you have wired and wifi - I use both on my desktop for redundancy

or for multithreaded tasks you can bond them together with something like dispatch/dispatch proxy

or with two identical (or similar cards) you can use NIC teaming

or with server 2012/windows 8 you can use multipath smb for MOAR SPEED.

enough reasons? ;p

Michael Frank

@JourneymanGeek :O

I WANT THIS

Journeyman Geek

@MichaelFrank: Apparently its by default, and samba 4.0 will support it

Michael Frank

I don't have two NICs though :(

Journeyman Geek

I have a mess of different things ;p

@MichaelFrank: I am slightly tempted to add a second, but there's really nothing on my home network that needs it ;p

I'm barely getting much use from gig-e since I have bottlenecks everywhere else ;p

"without the metal guard" = cost cutting ;p

Bob

@JourneymanGeek Or, easier filling :P

Apparently a similar Hero model has it, but some people prefer it without.

The say it's easier to get a good fill.

A: How to boot from CD even if BIOS doesn't allow this?

There's significantly simpler solutions to using a VM just to bootstrap an installation. I'd personally install plop bootloader - it chainloads your current bootloader, and lets you boot a currently unsupported device like a cd or usb key from it. Its much safer than using a VM (especially on a s...

Bob

@JourneymanGeek I dunno, but apparently they do - and those ones have terrible tips, leak, etc..

@JourneymanGeek I'm assuming it was one of those systems that needs a floppy boot disk.

I'd actually recommend that over installing another bootloader on-disk...

@JourneymanGeek The Hero actually slides and clicks shut very nicely.

Journeyman Geek

11:01

@Bob: I have no idea how he did what he thought he did

He formatted a system and reinstalled an OS by mounting the drive from a running system on the same drive

that shouldn't work ;p

Bob

@JourneymanGeek ...wut

Journeyman Geek

Thats how I parse the answer

Bob

@JourneymanGeek I think another method was to create a partition and 'burn' the CD onto it.

Journeyman Geek

You'd need a custom bootloader

and you can't resize a running partition

Bob

@JourneymanGeek Apparently most Linux distros will Just Work (TM)

Journeyman Geek

11:05

You could use a tool that re-sized it when you rebooted...

Bob

But I haven't tried.

Journeyman Geek

but thats not what he's doing

Bob

@JourneymanGeek Surprisingly - you actually can.

Journeyman Geek

@Bob: in windows XP? Using what?

Bob

Dunno about XP, but the built in Disk Management on 7 has no issues resising a running parition.

Journeyman Geek

11:06

I'm sure it'll fail if it isn't a dynamic disk

Bob

The problem is you can't move sertain FS structures and open files, so there's a limit on how much you can shrink it.

Journeyman Geek

However, none of this involves mounting a running system in a VM ;p

Bob

Ya.

Journeyman Geek

and if I was running windows 7, it isn't that hard to chainload something else, or boot off a VHD

Bob

That's just a recipe for disaster.

Journeyman Geek

11:07

and if its new enough, it bloody better USB boot

Bob

I'm sure XP isn't gonna be too happy with another OS clobbering its writes to NTFS structures.

@JourneymanGeek Booting off a VHD isn't the best way to replace the main OS :P

Journeyman Geek

@Bob: no, not really ;p

bleh, I need to wash my keys. Lazy though

Bob

@JourneymanGeek I can't decide if I should just start posting or change the blog software :P

Bob

comments are possible, but a bit of a hack

@JourneymanGeek I guess that's one way to handle it :P

CBenni

11:29

I have a couple of questions regaring VPS applications/setup if you dont mind...

Firstly, if I want to have my server (a DigitalOcean droplet) to be available under a url, say cbenni.com, I need to reserve the URL for that and somehow link the URL to the server

how do you do that?

Secondly, I still need to decide on the programming language I use, I need an application that runs 24/7 in the background and a website frontend; For the frontend, PHP on nginx/fastcgi is the way to go I feel

but what about the backend? Java has proven to be very resourcehungry

Journeyman Geek

you get a domain name, and set an A name pointing to the ip address of the VPS

Bob

@CBenni You register the domain name (not URL, URL is domain + path) with a domain registrar.

We like NameCheap here :P

They offer .com.

Journeyman Geek

and you're going about the wrong way in terms of 'front end/backend'

Bob

Then you go into their nameserver settings and set up an A record pointing to your VPS>

Which is what @JourneymanGeek said, but I didn't read until now :P

Journeyman Geek

You're 'only' going to need a web server/scripting language/(optional) db back end

Bob

11:33

@CBenni What kind of application is this?

Some larger enterprise systems have a backend you need to communicate with. Normally because this backend allows multiple services, from web to desktop to whathaveyou.

Journeyman Geek

I tend to run lighttpd/php-fpm/postgres (for ttrss) or the same stack with mysql for wordpress

Bob

Depending on what you're doing, splitting it off into a 'backend' and 'frontend' might be a bit... overkill.

Journeyman Geek

I also know of a guy who 'just' runs a python/django app and nothing else.

Bob

Personally, I hate PHP :P

Journeyman Geek

write what you know. run what you need. write what you need if nothing you have is good enough

Bob

11:35

And Java.

Journeyman Geek

@Bob: meh, a lot of cool stuff is php based. Pity about the language ;p

CBenni

mh, the application is PGSQL, connecting to IRC etc

Bob

You can write web services/apps with just about any server-side language (JS is a requirement for client-side, though there are some translation layers).

Journeyman Geek

@CBenni: so essentially a bot?

CBenni

meaning, it definitely has to run 24/7, while the website is just for controlling the bot

yeah

Journeyman Geek

11:36

I'd go with python

CBenni

a bit more than that, but essentially a bot

Bob

@JourneymanGeek Annnnd you beat me to it, again :P

Journeyman Geek

and have something on the website talking to the bot.

Bob

You don't necessarily need a separate website.

CBenni

I was considering python, and since I recently learned python while giving a python course ( :P ) I know a bit of it now

Journeyman Geek

11:36

or write the bot with a webapi to start with, and get your app to talk to the bot with curl ;)

Bob

The bot itself could also serve a website.

Journeyman Geek

yup

Bob

Though, the better way might be to have a separate bot.

In case one goes down. Also, it's generally cleaner.

You can then pass config changes through a unix socket or similar IPC.

CBenni

lemme read what you guys said real quick... :D

Journeyman Geek

eh

Bob

11:39

@CBenni I'd personally start with the bot. While building it, keep in mind how you want to communicate with it - generally some IPC method. Then a web interface that takes input and sends updates via the IPC should be fairly simple.

Just make sure you secure the web interface.

CBenni

ok, soo. I would have a python app running the bot, writing stuff into the database (PGSQL I guess) and then how do I best run the website? PHP/HTML on nginx? or can I somehow integrate that into the python script aswell?

Bob

As for the web interface, I'd recommend you stick with the same language, though that's by no means a requirement.

Journeyman Geek

@CBenni: python can run a web server perfectly well

CBenni

I have never created a webpage using python

Journeyman Geek

You'd probably want a framework like django or twisted

which makes life a lot easier

Bob

11:40

If you don't want to mess around with the proper/modern way of doing Python websites (WSGI, etc.), there's always plain CGI. Which is really easy to understand.

@JourneymanGeek For a basic web interface that doesn't really need to look pretty, all the MVC crap can end up being a hindrance, sometimes.

Journeyman Geek

@Bob: True, but that crap might help prevent technical debt

Bob

Of course, some of those can handle authentication for you, making securing it much easier.

Journeyman Geek

and a LOT of stuff is handled for you

^^^^ that

Bob

@JourneymanGeek Eh, a basic CGI Python script is very easy.

The learning curve is basically nonexistent.

(assuming you know some HTML, but you'll need that either method you choose)

For the heavier MVC stuff, I'd honestly not use Python (personal preference)

Journeyman Geek

@Bob: eh, I don't know much about programming. I do run a few python based apps, or have in the past ;p

CBenni

11:43

I know HTML and PHP very well, but I am new to server hosting

Journeyman Geek

@CBenni: eh, server hosting is simple after initial setup

Bob

Both Java (multiple methods, Servlets being the basic one, other options like Spring) and .NET (ASP.NET) are rather heavy, but can make large apps easier to develop/maintain and have better IDE support than Python.

CBenni

yeah the "initial setup" is where I am at ;)

Bob

But, those are far from optimal for a basic web interface to control a bot.

@CBenni So, register a domain name.

Point the A record to your server's IP

CBenni

also, will the 5$ droplet (512 mb ram, 1cpu, 30 gigs) suffice? The bot takes essentially 0 resources

Journeyman Geek

11:44

@CBenni: howtoforge has great install guides

Bob

install some webserver software and run it on port 80

Journeyman Geek

@CBenni: probably if its postgres

CBenni

okies

Journeyman Geek

my home testbox is probably less ram than that XD

Bob

@CBenni I tend to stretch resources for crap I don't care about. Yay 128MB VPSes! :P

But DO is almost certainly better as far as reliability goes.

Journeyman Geek

11:47

CBenni

ok, ill stick with the $5 one for now

soo, ill be doing alot of stuff now, thanks alot for your help until here
