In-class discussion: Introductory workshop

http://course.fast.ai/start.html

That’s a link to the getting started page; the AWS setup video is worth watching and very helpful, but will be somewhat different this year due to the new software setup (so don’t actually install the AMI, for example)

@yinterian Will Slack be used for communicating for this course or will everything be done through this forum ?

I remember @jeremy saying we would use discourse (this forum) for all the discussions and communications. If you want mobile access to forum you can download the discourse app and link forums.fast.ai to stay connected.

Hello world!

I like this guide in particular because it discusses how to setup SSH with no password.

This is awesome because I can login my rig from anywhere and still use my mac :slight_smile:

Thanks to everyone who contributed code snippets, links, etc to this discussion. The next step is to get all this stuff consolidated into the wiki thread, which is here: Wiki thread: Intro workshop . Anyone who has a moment and is interested in reviewing what was shared during the lesson, please help us by copying useful snippets from this thread into the wiki thread - thanks! :slight_smile:

Any update on this possibility @jeremy?

I don’t have any particular connections there in appropriate places to ask for this. If anyone here does, feel free to ask!

I got this error while SSHing
sumanths-MacBook-Pro:~ sumanthnandamuri$ ssh -i .ssh/fastai.pem.txt ubuntu@54.237.97.183
ssh: connect to host 54.237.97.183 port 22: Connection refused

I think that is because of proxy for my internet connection, someone please help me resolve this issue i.e how to make ssh work with an internet connection with proxy ??

Hi Ankit,

In my case my key file is downloaded in the windows download folder. How can I move it to the .ssh in ubuntu using powershell?

Once this is done I can run ssh -i .ssh/aws-key.pem ubuntu@AWS IP xx.xxx.xx.xxx

Anyone faced same issue.

Rgrds,

@ravimahar
Do copy the contents of the the aws_key_pair file in Windows by opening it in a suitable editor…
After that,
in WSL type

'$>touch <aws_key_file_name>.pem 
in the .ssh/ directory (as in the video)
$>nano <same_file_name.pem> followed by a left-click
and then ctrl+X and Y
$>cd ..
$> ssh command..'

Mission Accomplished…
Hope it helps…

Thanks Aditya. I did as instructed but getting below error.
