An interruption / maintenance for these February 13rd took place for migration of the calculation nodes to a new system.

New login.matrics.u-picardie.fr !

$ ssh Your_login@login.matrics.u-picardie.fr
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: POSSIBLE DNS SPOOFING DETECTED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
The ECDSA host key for login.matrics.u-picardie.fr has changed,
and the key for the corresponding IP address 194.57.107.34
is unchanged. 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.
Offending key for IP in /home/renault/.ssh/known_hosts:11
remove with:
ssh-keygen -f "/xxxxx/xxx/.ssh/known_hosts" -R "194.57.107.34"
