If I want to specify for LAN addresses that I don't want to deal with host keys, how do I do that? Understanding the risks, knowing almost everyone will say not to do this - it's a horrible idea, but deciding I want to do it anyway. Tired of having to remove entries from known_hosts with the multiple VM's I have that often change fingerprints, and am willing to live with the risks.

Perfect, thanks. This winds up working for me (as far as I've tested so far.) Match exec "ping -q -c 1 -t 1 %n | grep '192\.168\.'"

Hello & thanks for reading. I'm having a problem configuring known_hosts from scripts so an accept key yes/no prompt doesn't appear. I'm using this command to detect if the server is known and add it to known_hosts: if ! ssh-keygen -F ${IP_ADDR} -f ~/.ssh/known_hosts > /dev/null 2>&1; t hen ssh-keyscan -p ${PORT} ${IP_ADDR} >> ~/.ssh/known_hosts; fi This works

Well, first I disagree that this method is improper. The

Trying to get SSH agent forwarding working for a popular open source configuration management system called Ansible. I?ve had some unexpected behaviour, the only cause of which I can find is how I express the command line arguments. http://stackoverflow.com/questions/20952689/vagrant-ssh-agent-forwarding-how-is-it-working?noredirect=1#comment31511341_20952689 In summarise: In the first

Hello there, I'm a little afraid of writing here, hope I don't make any mistake doing so. I'm trying for days and searching the web too, but no obvious solution, no reply from the specialized forum I wrote in. Here is the situation: I would like to have a lighter security inside our domain, without changing when going outside. By "lighter security" I mean at least, no

As far as I can tell, there currently isn't a straightforward way to use password authentication for connecting to hosts where the host key changes frequently. I realize this is a fairly niche use case, but when developing software for devices that often get reimaged (resulting in a host key change), it can get pretty tedious to attempt to connect, get a warning, remove the old host key via

Hi! Is it somehow possible to disable the known_hosts checking for some hosts? The StrictHostKeyChecking affects only the asking about new computers, but doesn't affect the changed ones. I need it for the test computers, which are reinstalled twice/hour and I really don't like editing .ssh/known_hosts each time :-( Thanks Michal

Let me start by saying that I think OpenSSH is a great tool and thanks to everyone contributing to it's existence. However, I have a request: I'd like to have a flag that ignores the check of the host key. I'm fully aware of that this opens up for man-in-the-middle attacks and that there is a risk of lazy users mis-using this feature, but it would be very useful for us using SSH in a
