After over a month, I have managed to piece together how to setup an AWS EC2 server. It has been very hard to upload files as there are very conservative (size) limits when done via the upload button in Rstudio Server. The error message when this is attempted is "Unexpected empty response from server".
I am not unique in this respect e.g. Trouble Uploading Large Files to RStudio using Louis Aslett's AMI on EC2
I have managed to use the following commands through putty and this has allowed me to upload files via either filezilla or winscp.
sudo chown -R ubuntu /home/rstudio
sudo chmod -R 755 /home/rstudio
Once I use these commands and log out, I can no longer access rstudio on the instances in future logins. I can relogin to my instances via my browser, but I get the error message: Error Occurred During Transmission
Everything is fine other than once I use Putty I lose browser access to my instances.
I think this is because the command is change of ownership or similar. Should I be using a different command?
If I don't use a command I cannot connect between filezilla/winscp and the instance.
If anyone is thinking of posting a comment that this should be closed as it is a hardware issue, I don't have a problem with hardware. I am interested in the correct coded commands.
Thank you :)
Ok so eventually I realised what was going on here. The default home directory size for AWS is less than 8-10GB regardless of the size of your instance. As this as trying to upload to home then there was not enough room. An experienced linux user would not have fallen into this trap, but hopefully any other windows users new to this who come across this problem will see this. If you upload into a different drive on the instance then this can be solved. As the Louis Aslett Rstudio AMI is based in this 8-10GB space then you will have to set your working directory outside this, the home directory. Not intuitively apparent from Rstudio server interface. Whilst this is an advanced forum and this is a rookie error I am hoping no one deletes this question as I spent months on this and I think someone else will too.
Don't change the rights of /home/rstudio unless you know what you are doing, this may cause unexpected issues (and it actually does cause issues in your case). Instead, copy the files with filezilla or winscp to a temporary file (let say /tmp), then ssh to your instance with putty and move the file to the rstudio directory with sudo (e.g sudo mv /tmp/myfile /home/rstudio).
