I'm setting up a "data analysis on the cloud" class and most of the students will probably be using Windows.
The students will have to set up EC2 Ubuntu instances and connect to them.
What is the easiest way to set up SSH for Windows XP-7?
I've tried PuTTY but Puttygen can only convert the public key to putty format if I manually add newlines in a text editor. This is too involved for the class of 80.
I've tried OpenSSH but I can't seem to find the correct permissions for the public key file. On Mac OS/Linux it's just chmod 600
.
Is there a decent SSH client that supports Amazon's key format that I can set up easily?
亚马逊网络服务为您提供的 .pem 文件由 openssh 客户端实现支持,但对于直接使用 .pem 文件而不使用 puttygen.exe 进行转换的基于 Windows 的客户端,请查看Bitvise Tunnelier 。
Another possible solution is to use PuTTY but follow Amazon's guide for doing so. I found some other guide's that weren't as clear in the steps but I was able to get PuTTYgen to work correctly when I used their guide.
As for newlines, maybe you need to run unix2dos or some other program that will fix that for you?
Step1: Download the keypair
The download will create a .pem file on your local system. It contains a private key that you can use to connect to the EC2 instance via SSH
Step 2: Launch your linux instance
Copy the public ip address for the future use to connect the linux instance
Step 3: Download puttyGen from https://the.earth.li/~sgtatham/putty/latest/w32/puttygen.exe
Step 4: Execute the PuttyGen exe and load the private key(the pem file you have downloaded while launching the instance)
Step 5: Save the private key, it will give the .ppk file which will be used to connect the linux instance
Step 6: Download and install the Putty software, open the putty, and paste the public ip address which you copied from the linux instance
Step 7: Now load the .PPK file which we have saved
If anybody's looking for windows 10 solution.
In Windows 10, you can use powershell. Use above command.
ssh -i \..\location-to-pem-file.pem ubuntu@X.X.XXX.XXX
If ssh is not supported in your windows 10 machine, follow this url for installation.
I used it and suggested the same.
I borrowed the method giving in this video. https://youtu.be/P1erVo5X3Bs Open power shell and run below commands. You can open power shell at any location by print powershell in the nevigation bar and press enter. enter image description here
1.reset premission:
icals.exe key.pem /reset
2.check the current user id
whoami
3.add permision to specific user id
icacls.exe key.pem /grant:r "YOUR USER ID GIVEN BY WHOAMI"
4.remove permission of other user
icacls.exe .\ec2.pem /inheritance:r
Now it should work.
If anybody's looking for windows 10 solution.
icacls.exe .\Desktop\xxxx.pem /reset
icacls.exe .\Desktop\xxxx.pem /grant:r "$($env:USERNAME):(r)"
icacls.exe .\Desktop\xxxx.pem /inheritance:r
ssh -i .\Desktop\xxxx.pem ec2-user@54.229.xxx.x
