Git says “Warning: Permanently added to the list o

Question

Every time I use git to interact with a remote, such as when pulling or pushing, I am shown the following message:

Warning: Permanently added '...' (RSA) to the list of known hosts.

How can I prevent this annoying message from displaying? It is only an annoyance—everything functions properly.

Answer 1

That message is from SSH, which is warning you that you are connecting to a host which you've never connected to before. I wouldn't recommend turning it off, since it would mean that you might miss a warning about a host key changing, which can indicate a MITM attack on your SSH session.

Answer 2

To suppress warning messages for ssh you can add the following lines to ~/.ssh/config:

Host *
LogLevel error

That will disable warnings but not error messages. Like the other settings in ~/.ssh/config you can configure the LogLevel on a per-host basis if you want a more finegrained control.

Answer 3

Add ssh key

ssh-keygen -t rsa -b 4096 -C "[e-mail]"

eval "$(ssh-agent -s)"

ssh-add ~/.ssh/bitbucket_rsa

crate config file

crate ~/.ssh/config

add below line.

UserKnownHostsFile ~/.ssh/known_hosts

Then add pub key and clone your repository... Done.....

Answer 4

I had faced the same error in Linux/Cent OS VM and it was because the IP was changing after restart. In order to get around this problem, I defined a static IP in the network and added that entry to /etc/hosts file. For static IP mention a slightly higher range value. For example if your current IP (ipconfig/ifconfig) is 192.168.0.102, next time after restart this may become 192.168.0.103. So define your static IP in IPV4 settings as 192.168.0.181 which should do the trick.

Answer 5

Solution: create a ~/.ssh/config file and insert the line:

UserKnownHostsFile ~/.ssh/known_hosts

You will then see the message the next time you access Github, but after that you'll not see it anymore because the host is added to the known_hosts file. This fixes the issue, rather than just hiding the log message.

This problem was bugging me for quite some time. The problem occurs because the OpenSSH client compiled for Windows doesn't check the known_hosts file in ~/.ssh/known_hosts

ssh -vvvvvvvvvvvvvvvvvvv [e-mail]

debug3: check_host_in_hostfile: filename /dev/null
debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts
debug3: check_host_in_hostfile: filename /dev/null
debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts
Warning: Permanently added 'github.com,207.97.227.239' (RSA) to the list of known hosts.

Answer 6

Set LogLevel to ERROR (not QUIET) in ~/.ssh/config file to avoid seeing these errors:

Host *
   StrictHostKeyChecking no
   UserKnownHostsFile /dev/null
   LogLevel ERROR
