[ecco-support] Problems accessing Research Servers

[Tingyi Lu]

Hi,

I'm working on a UROP with Sara Ellison, and I'm trying to get access to the research servers. I think Tommy has already spoken to Carl about this issue, but I'm getting some errors in the process. I already had access to the server a year ago, but it no longer seems to work.

When I enter ssh tingyilu at supply.mit.edu into my terminal, I get the following message:


@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@       WARNING: POSSIBLE DNS SPOOFING DETECTED!          @

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

The ECDSA host key for supply.mit.edu has changed,

and the key for the corresponding IP address 18.1.35.57

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:dptCPySal3/F5jGNnUmVzEccgxVU2+YwP0aPrk2W39Y.

Please contact your system administrator.

Add correct host key in /Users/tinalu/.ssh/known_hosts to get rid of this message.

Offending ECDSA key in /Users/tinalu/.ssh/known_hosts:1

ECDSA host key for supply.mit.edu has changed and you have requested strict checking.

Host key verification failed.


If you know how to fix this issue, I would really appreciate it!

Thank you!
Tina Lu
