Where can i host a file to be downloaded

The script will loop over the names sites and modify the. The GitHub and GitLab keys may change if they get compromised. In this case, check the most recent ones here and there. Remark : You may need to ensure that the key is not added twice. For this, refer to other answers. This is the only way to authenticate the server. Without it, your SSH connection can be subject to a man-in-the-middle attack.

The first "accept-new" will automatically accept hitherto-unseen keys but will refuse connections for changed or invalid hostkeys. This is mostly write enabled even in a read-only file system. If you already have a. I'm setting up a test harness that will, from a central client, launch a number of virtual machine instances and then execute commands on them via ssh.

This answer from StackOverflow has a better more correct answer. You must obtain the. Since those are "VM's", you should be able to go into them by other means ex: mount the filesystem , and get the keys. Or the other way back: push a known private key on each slave by accessing the filesystem of the VM's. This solution is overkill for simple cases where you master your environment, but it is not sensible to "men-in-the-middle" attack I'm creating a fabric 2.

At one point, it will create a ssh key, and add the public key to gitlab using it's api. Then, it will clone a repo containing the website source code.

The clone command failed in the script, and when I went on the server and manually launched the command I had the The authenticity of host 'host. Sign up to join this community.

The problem I'm having is that the first ssh command run against a new virtual instance always comes up with an interactive prompt: The authenticity of host '[hostname] [IP address] ' can't be established.

RSA key fingerprint is [key fingerprint]. Improve this question. For a test environment which is self-contained and physically secure, automated key acceptance may work just fine. But automatically accepting public keys in a production environment or across an untrusted network such as the Internet completely bypasses any protection against man-in-the-middle attacks that SSH would otherwise afford.

The only valid way to make sure you're secure against MITM attacks is to verify the host's public key through some out-of-band trusted channel. There is no secure way to automate it without setting up a moderately complicated key signing infrastructure. Add a comment. This should permit the download to go ahead next time you download a file from the host.

We have done so for Ingenta - see the link to a separate FAQ on this. Look also for pop-up alerts near the top of the browser and enable the pop-up if you trust the site - the publishers' sites that we link to may be trusted as they are known to us. Once the pop-up is enabled, it may open automatically, or you may need to refresh the page you were on. If no solution works for you, please email e-library brunel. Was this helpful? Yes 7 No If you need to add a key during a build process then you should follow steps of the manual process above.

Having done that, examine the contents of your github-key-temp file and make a script to add those contents to your known hosts file. You should now get rid of any ssh commands which have StrictHostKeyChecking disabled. The easiest way is to manually fetch the keys using ssh-keyscan , verify them manually:.

I have been trying to do this in Python on Jupyterhub for a little while but Michael's answer was really helpful! Let us be clear -- by design this step to confirm a known host should NOT be automated given susceptibility to man in the middle attacks more info here , but it should be obvious why this is a concern. The insecure workaround -o "StrictHostKeyChecking no" was alright for testing but glad to have an alternative. You can now use a python assertion to ensure authenticity of our trusted RSA fingerprint vs the Scanned-over-your-internet RSA fingerprint:.

So far, I've found I guess I'm asking the following: How do I get the fingerprint for a key returned by ssh-keyscan?

That's kind of a good thing, unless you're releasing a new version of your software and signing with a brand new certificate. While an EV Code Signing Certificate does get you instant reputation with SmartScreen, it is relatively easy to gain reputation using a standard certificate too. You need a computer, Internet Explorer or Edge and a bit of time. Do that about multiple times and the the messages will go away relatively quickly.
