Hi,
I think it's possible an analysis I left running might have created more files than what I had available and now I am not being able to SSH. Could you please check this situation, this is what I get:
ssh asilva@core.cluster.france-bioinformatique.fr
kex_exchange_identification: Connection closed by remote host
Thanks for your help
Ana
Hi Ana
We have had to reboot the login node to resolve the access issue. You should be able to ssh to it now.
Thanks Nicole
Thank you so much for your fast reply, it works now!
Cheers,
Ana
Bonjour,
J'ai le même message d'erreur lorsque je tente de me connecter, il semble que le problème ne soit pas résolu pour moi.
Merci!
Bonjour Alexis,
En effet, nous avons aussi constaté des problèmes de connexions.
Nous avons pris d'autres mesures (ban IP). Cela devrait être bon maintenant.
C'est réglé, merci pour la réactivité !
Anyone else not being able to ssh? It asks me for my password but then nothing happens, as if it is stuck.
Thanks for your help
Ana
Hi @asilva
I don't see any error on our side.
Coul you retry or try in a verbose mode (ssh -vvv) to debug ?
Thanks for your fast reply, maybe it's my work internet connection, going to try in a bit at home. Here is the output of the verbose mode:

Thanks!
No error with your account, the storage or on our server.
Maybe there is something wrong with your environment or with your locale settings (LANG = en_AU.UTF-8).
Could you try to unset local variables and reconnect:
unset LANG
unset LC_MONETARY
unset LC_NUMERIC
unset LC_MESSAGES
unset LC_COLLATE
unset LC_CTYPE
ssh asilva@core.cluster.france-bioinformatique.fr
Or just restart your computer and retry ?
Thanks for your help, it seems to work from home so it might have been something with internet at work which is weird because I was able to use another cluster. It was the first time I tried ssh with nothing happening but next time I know it might be more about my connection than the cluster.
Thanks!
Hi,
Apologies for yet another issue with ssh, I think this time I might have done a mistake when I was doing a test with LINK, but then it got stuck without me being able to cancel it, and now I am trying to ssh again but without success.
Sorry for this
Thanks for your help
Ana
Hi @asilva
Maybe just some slowness on core.cluster.france-bioinformatique.fr server. It's seems ok now.
Could you retry ?
It works! Thanks again for your patience.
Cheers,
Ana
