In November 2018, gcc118 suffered from a filesystem issue after upgrading the kernel.
Thanks to the excellent support from OSUOSL students, the machine has been reinstalled with a more recent OpenSUSE version (15.0) and is available again for farm usage! Unfortunately, we couldn't recover any user data.
The SSH key of the server has changed. You will need to clear the old key from your
ssh-keygen -R gcc118.fsffrance.org
ssh-keygen -R 126.96.36.199
We will look at a way to backup the server SSH keys on all machines to avoid this kind of inconvenience in the future.
