Intro to SSH (Secure Shell) Part 1: What is SSH, and Why do I want to use it?

[xXphilipcuiXx]

Thanks for explaining of what SSH is in such short concise video.

[Msripper97]

and masterbating over ssh 1:50

[mysteryloser24]

Of course SSH works on Android and the iPhone. Android uses a stripped down Linux kernel and the iOS is a UNIX-like system, same as Linux.

[glowcode]

I installed a bash/ssh terminal emulator to my android phone and ssh'd into my desktop's vm's.

[Vorbis5]

you made me subscribe

[Jzarecta]

I notice that you have lots of C++ books, would be nice if you can talk a bit about C++ tools in Linux.

Maybe reviewing IDEs like Ajunta.

[lolascestlavie]

you talk like my professor....

[mgedier]

man, thank you very much for your videos, Im an Engineering student and your videos help me too much!!!

[Freespire44]

Jordon Shs sounds like some thing I could use because I have stories I'm writing and wanted it to share them with others but was worried they;d get swiped over the inter net . Now on a Different subject, Since your going to write and sing your own songs. I would like to suggest Jamendo as a great place to send your songs so that others can hear them over the Inter net. What's More Jamendo use Creative Commons. That Helps artist who want to share their work with others.

[thisweekinlinux]

@Freespire44 depending on who you're sharing it with, ssh/scp might work, but it requires a login to the person's computer.

About the music, I wasn't planning on making my content Creative Commons, sorry.

[morgohill]

bsd remember open ssh was ported from bsd

[morgohill]

bsd rember open ssh was ported from bsd

[QueeeeenZ]

Hey Jordan, why don't you allow your videos to be downloaded from YouTube like other partners do..

from Google answers...

"Some partners on YouTube allow you to download their videos in the MP4 file format, using the H.264 video codec and the AAC audio codec."

[thisweekinlinux]

@QueeeeenZ I don't have the option to make it available for download.

[analyzingfunny]

lolol Twill sings...this should be good. You can do all of this (ssl) but cant broadcast a series of videos to JTV (the standard of quality). I dont get it...come on man.show us this JTVLC thing, and we can learn about tar files and how to install them at the same time.

[thisweekinlinux]

@analyzingfunny I can broadcast to JTV, just can't get sound working. I'm working on it, man...

[AnxiousNut]

Just don't forget to mention ssh in nautilus feature! ;)

[thisweekinlinux]

@AnxiousNut will do

[fatkasuvayu]

Hey Jordan,

quick question did you really mean pipe an application over ssh or were you referring to piping the output of one program over ssh to some other machine? something like this,

remote$ cat image.png | ssh local display -

[thisweekinlinux]

@fatkasuvayu you could do that as well, but I was talking about forwarding an X-based application over ssh.

[fatkasuvayu]

@thisweekinlinux ah ok, usually i m working on machines across the pond, so not a very good option for me :-p I wish there was a good solution to that ... I try to keep things always on the terminal but often its just not possible to avoid the gui any more :-/

[thisweekinlinux]

@antimatterball21 if I remember correctly, I don't think Ubuntu comes with openssh-server preinstalled.

[dxiri]

also you should include some troubleshooting steps :D

[thegasgranny]

Hi Jordon!

It would be nice to see how to setup remote desktop access using the SSH server service. Even nice would be how to setup remote access to your desktop over the net :)

Cheers.

TGG.

[thisweekinlinux]

@thegasgranny will do

[francccis]

@thisweekinlinux AppArmor vs SELinux would be great! Really appreciated

[rtsownage]

What a coincidence, I just set up an open SSH server for the first time last week. Very interested in the port forwarding stuff though :)

[alambpencil]

looking forward to more on this!

[thisweekinlinux]

@GrudgyDiablo I use Kdenlive for all my video editing.

[supereater14]

can you talk about scp?

[thisweekinlinux]

@supereater14 that's the plan. one of the most useful features, imho.

[TheAndroid111000]

When is part 2 out?

[thisweekinlinux]

@TheAndroid111000 planning to do it this coming week. working on laying out an actual schedule for the future.

[FNCelliers]

I would like some information on the actual encryption type of ssh. Is it 128bit or what?

[thisweekinlinux]

@FNCelliers it depends on the encryption type you choose. OpenSSH supports different methods (Triple DES, Blowfish, AES, Arcfour)

[TheFusionIcon]

I have a feeling this is going to be one of the best and most useful tutorial series you have made so far. Thank you!

[thisweekinlinux]

@TheFusionIcon I hope so!

[pritamdodeja]

You're awesome! Keep up the good work!

[japafi]

Topics you should cover: ssh tunneling, reverse tunneling, example of using such tunnels eg nat connections (vnc?), disabling interactive authentication in favor of public key auth, ssh-agent (not having to type in your passwd several times), etc.

[thisweekinlinux]

@japafi excellent suggestions. I'll try to cover some of those.

[Donflorgon]

Thanks, finally something new & practical I can learn about Linux!

Ive never tried to learn SSH

[thisweekinlinux]

@Donflorgon it's insanely useful.

[Tununias]

Free BSD, Net BSD, Open BSD, ReactOS, Solaris, Open Solaris, Haiku, Free DOS, thats all I can think of off the top of my head.

[thisweekinlinux]

@Tununias they all work with it, as far as I know. :)

[TheSushiDude]

What about setting up a Socks5 Proxy?

[thisweekinlinux]

@TheSushiDude is that SSH-related?

[francccis]

How about an intro to SELinux?

[thisweekinlinux]

@francccis to be honest, I tend to disable it, especially now that AppArmor is built into the kernel.

At some point I really need to get back into doing the TWILTalks (the actual topical vlogs on the second channel) and do an SELinux vs AppArmor talk.

[kcj1993]

Can't wait for the next video!

[russjr08]

Yay! Can't wait for the next! Also, are you working on the Arch Wireless Tutorial? Hopefully after that tutorial, I can install it on my laptop!

[thisweekinlinux]

@russjr08 that's the next Arch one to come, I just have to get myself motivated to wipe out everything on my laptop...

[woeskwee]

Glad to see you getting back to tutorials; yours are the best.

More Linux please!

[thisweekinlinux]

@woeskwee agreed. more tutorials, more distro reviews to come. :)

[foxh8er]

1 person uses Windows 98.

All kidding aside, excellent intro. Something I have always wanted to know, but never could find out. 

[marios2liquid]

Waiting for the next ssh tutorial woooo!!

[papagaulo]

Dude I always watch you but now I have to put you up there with gotbletu nixie pixel and metalx so glad your are delving deaper into tutorials

[thisweekinlinux]

@papagaulo woohoo!

[apagao666]

That's nice , I am waiting the next video

[mytube232]

@thisweekinlinux It would be great is you could go over seahorse. That little proggie enables easy setup of key based authentications for SSH. All you need to do is to generate a key, enter server IP or domain where key should be used to login and then enter username and password on that server. Program will do the rest...

[thisweekinlinux]

@mytube232 nice suggestion.

[mytube232]

@thisweekinlinux glad you like it. I know that program helped me a lot!

[TWILisawesome]

I find SSH and VNC are useful for pranking my parents from my laptop. :P

I want these tutorials! They are going to be soooo useful. Will you be touching on VNC, or is it strictly SSH? I personally prefer VNC because it gives me a GUI. But, is it possible to share files with VNC?

[mytube232]

@TWILisawesome VNC and SSH are two completely unrelated things. VNC is a remote desktop protocol while SSH is used mainly for remote administration by issuing commands (and many other uses). Former transmits image stream, while SSH sends commands.

[thisweekinlinux]

@TWILisawesome @mytube232 is right, VNC and SSH are entirely different. You can, however, run VNC over SSH, so all the data from the remote desktop session is encrypted from one end to the other.

[linuxsport]

I use ssh with my GF... Go make me a sandwhich and sshhhhhhh...

[thisweekinlinux]

@linuxsport nice one.

[roflschofel]

Have been using SSH for 2weeks now. Just doing it over the local network since the SSD in my little thinkpad isn't ideal for mass storage. Will be watching these to see the last few things I might have missed.

[analyzingfunny]

Thank god you are not singing dancing and playing guitar in a friggin penguin suit...

Any chance you can show us all the mystery that is brocasting with Linux to JTV? This is very important. Show us how to do this. I cannot get any help. No camera, just a playlist of 10 vids, test patterns or something keep playing in a loop.

[thisweekinlinux]

@analyzingfunny yeah, I can do that, shouldn't take long. just have to change the security settings for flash.

[analyzingfunny]

@thisweekinlinux OH THANK YOU, THANK YOU THANK YOU. I need to broadcast a list of 10 videos in a loop to JTV. JTV is the only one messing with. The wiki page says you have to use JTVLC with VLC? Please do this WITHOUT the camera to makes things simple. Do a separate vid on that. I feel this is very important to mankind to know how to broadcast int his powerful effective medium.

and again thank you

[thisweekinlinux]

@analyzingfunny oh, my mistake, I misread. i thought you wanted to stream a camera. It's possible to stream through jtvlc, but I haven't had any luck getting audio to stream.

[analyzingfunny]

@thisweekinlinux (As Homer Simpson) "DAMN YOU!!! Damn you to hell!!!!"

[miscible21]

Great video! Looking forward to the rest.

[qadison]

can it stop man in the middle attacks?

[elnegrobembon]

@qadison

all the data going to and from an ssh client and ssh server is encrypted. that way, if a person was to do a man in the middle attack, all he/she would see is junk.

so technically, i don't think it stops people from doing a man in the middle attack, but there would not be really any point in doing it because the info they get is worthless...

[qadison]

@elnegrobembon thanks 

[sekal123]

I use ssh a lot lately, but i will watch yout tutorials just for un. Maybe i will learn something new.

[04IT934]

nice initiative....

[gaglamesh731]

Can't wait for the series to be complete :D

[EleCtrOx666]

Links at the end to other videos don't work with me :/ Well I'm under Windows currently may be the cause \o/(ok just trolling, I doubt it is Windows :) ).

[thisweekinlinux]

@EleCtrOx666 ooooops, haven't done the annotations yet. I fail! :) About to go home for lunch, and I'll do it then. Thanks for the reminder!

[QueeeeenZ]

SSH is totally new to me but I have always wanted to learn it cuz all the cool guys are talking about it :) Looking forward to more videos SOON! :)

[elnegrobembon]

i already know a little about ssh, but the way you worded the part about x forwarding and viewing applications on remote computers was a little confusing lol! at least i think it would confuse me if i was a noobie with no experience with ssh...

btw, i like that new music you got there...

[thisweekinlinux]

@elnegrobembon yeah, watching it back I can see the X forwarding stuff being a bit confusing. when the time comes, I'll try to take it slow and explain exactly what's going on.

Thanks! That's actually something I threw together in like 3 minutes on my piano last night.

[Ki12B]

SSH can transmit data? So I could deinstall FileZilla?

[thisweekinlinux]

@Ki12B you can actually use FileZilla to connect to an SSH(SCP) server

[Ki12B]

@thisweekinlinux I know but I would like to know, how I could copy data from my HDD to the server due an SSH-Terminal.

[bmw328driver]

Great subject; I am looking forward to future episodes in this tutorial series. I hope the series might lead up to covering secure remote desktop access via VNC over an SSH tunnel. I would suggest recommending to people that telnet and ftp, due to their security risks, probably should not be used anymore, replaced by ssh and sftp / scp, respectively.

[thisweekinlinux]

@bmw328driver that is indeed one of the things I want to talk about (as well as how to do it from Windows, because it's something I have to do pretty often).

The ftp/telnet insecurity thing was one item I was trying to stress with this video. plaintext = bad.

[fantasmaofdoom]

Ok this is interesting! Looking forward to it!

[THEKINGOFEUR0PE]

Will SSH make my wireless card work on linux?

[thisweekinlinux]

@THEKINGOFEUR0PE not that I know of.

[THEKINGOFEUR0PE]

@thisweekinlinux QQ

[thisweekinlinux]

@THEKINGOFEUR0PE what sort of wireless card do you have, and what distro are you on?

[THEKINGOFEUR0PE]

@thisweekinlinux

Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)

Linux Mint 10

I'm at work currently and the laptop is at home.

[thisweekinlinux]

@THEKINGOFEUR0PE Crap, I remember seeing this in my inbox, started researching for it, and something else came up. Sorry, man.

According to community.linuxmint. com/hardware/view/1042, it says it worked perfectly out of the box with Isadora (LM 9), so in theory it should be working in LM10, unless they broke something. Hm, according to greendusk. com/?p=433, you need to download the firmware for ipw2200 and copy it to /lib/firmware.

[THEKINGOFEUR0PE]

@thisweekinlinux oh cool! I'll try this when I get home! Thanks so much! :D

At the moment I'm trying to save servers from melting! Our server air con has broke lol!

[mohamedansari05]

Can't wait

[davexunit]

This will be a great series. I use ssh all the time at my internship. Hoping to learn some new tricks. :]

[saket3143]

What about Live shows

lets like if u want more shows

[Carrera1123]

SSH is the best remote-control tool ever... i have 0 port forwardings on my router, but about 20 (reverse)-ssh-tunnels from my machines in my home network to server in germany... i loooove it... over these things i'm able to mount my raid(in the dektop) to every machine i'm working on, i can control my lights at home over these tunnels (got a embeded linux system which handles everythin). i can do EVERYTHING with HIGH-SECURITY! tell me that on a default windows system with unsecure samba/telnet!

[thisweekinlinux]

@Carrera1123 I've never tried reverse ssh, to be honest. I'll need to read up on it, and perhaps make a video about that too. :P

[Carrera1123]

@thisweekinlinux i promise: you'll never touch portforwarding again if you have set up properly these reverse tunnels... because the security aspect is just so great! if you need some information about how i did (to make shure a tunnel is up 7/24 and tricks like that), just ask;-) btw looking forward to the tutorials! i'm sure i going to learn some new tricks i wasn't aware of before...;-)

[thisweekinlinux]

@Carrera1123 I would definitely appreciate any information you could pass along. :) Just shoot me an email, admin@thisweekinlinux. com

[elnegrobembon]

@Carrera1123

i've never heard of that... that sounds pretty cool. i hope we see that in the tutorials because i would love to learn about that too...

[Carrera1123]

@elnegrobembon i love it!=) i hope you gonna hear it! i just sent him an e-mail with an howto. hope he's digging it! if yes you probably gonna know everything you need;-) otherwise write me an PM and i'll send you the same e-mail.

[elnegrobembon]

@Carrera1123

cool. thanks a lot man! i think i'll give him a chance to put up a video though and see how it comes out. i like the way he does his tutorials. if not, then i'll definitely send you a pm for the info.

[siechtum]

Damn. Have you read my mind? I was connecting a LMDE PC with a LM PC yesterday over LAN.

[thisweekinlinux]

@siechtum ssh can definitely help out there. :) 

[thisweekinlinux]

@movogra I think it should be possible to do that. I'll keep reading and see if I can find a good way

[GreenMeanieUK]

Awesome iv literally been thinking about learning about setting up servers.

Thanks

[thisweekinlinux]

@GreenMeanieUK awesome! I'm hoping to talk more about servers in the future (possibly Apache, CMS's like Wordpress/Joomla/Drupal, media sharing servers, stuff like that)

[elnegrobembon]

@thisweekinlinux

that would be great for me too... i've also been wondering about how to go about setting up servers in linux.

are you also thinking about doing tutorials about how to set up domain controllers and active directory in linux??

i've been looking for some good tutorials about that, setting up group policies, and basically trying to replace a windows dc with a linux dc...

linux seems to be a good option for all kinds of servers, so i'd definitely love to learn about that...

[psychoclown420]

I used to use it a lot to install custom themes on my jailbroken ipod touch and to install windows 95 on it. Yes, windows 95 ran on it, but unfortunately it was so slow, that it was basically unusable. Maybe it would run better on the 4th generation models with the 1ghz processor and 256mb ram.. I also had a macintosh-plus emulator on it and i used ssh to move the roms over to my ipod. I had OS 1.0 running smooth as silk

[thisweekinlinux]

@psychoclown420 win95 on a touch? wow.

[fakaras99]

I can't wait to see the next video

[hfsjansharr]

Cool! I SSH everyday, I ssh all my traffic when Im at a wifi cafe. I set up a $20 a mo virtual machine in Fremont (ca) for that very purpose. I also set up aliases in my .bashrc file so I dont have to type: "ssh -D 8080 username@xxxx.xxx.xxx.xxx" in terminal every time. Also setting up socks5 in Chrome is a breeze.More people should do/know about this.

[hfsjansharr]

@hfsjansharr oops I should mention that I route my wifi cafe traffic through that virtual machine in Fremont.

[thisweekinlinux]

@hfsjansharr Nicely done. :)

Generally I use SSH for doing stuff at home while I'm at work, and I can reconnect to a screen session to just pick back up where I left off.

I've also used it to tunnel ports for web proxy, like you mentioned. :)

[pacorocks1]

X11 fowarding FTW!

[tazz1418]

you should sell me your iPhone !

[thisweekinlinux]

@tazz1418 planning to stick it up on eBay sometime soon if you're interested in it. got to pay off the AT&T early termination fee. :P
