Dear participants,
We have undergone a maintenance of our evaluation system. It took a bit longer than expected, so thank you very much for your patience!
After the maintenance, you may encounter the following problem when you want to clone, push, etc. to your repo with the following error message.
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: POSSIBLE DNS SPOOFING DETECTED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
The ECDSA host key for gitlab.aicrowd.com has changed,
and the key for the corresponding IP address 52.71.130.83
is unknown. This could either mean that
DNS SPOOFING is happening or the IP address for the host
and its host key have changed at the same time.
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:9OaZOZ1sUusrIvpRucI9yLCZNWzs1mN6FFVT7zm+PuI.
Please contact your system administrator.
Add correct host key in /home/ec2-user/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/ec2-user/.ssh/known_hosts:1
ECDSA host key for gitlab.aicrowd.com has changed and you have requested strict checking.
Host key verification failed.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
This is expected, as aicrowd migrated their server. There are two ways, either of which should resolve the problem.
- Run the command
ssh-keygen -f ~/.ssh/known_hosts -R gitlab.aicrowd.com. - Open the file
~/.ssh/known_hosts, and delete the line that corresponds togitlab.aicrowd.com.
Best,
Yilun Jin
