CVS access probably blocked

Hello list, As a newcomer, I've tried to setup my account on fas.rpmfusion.org, and uploaded my RSA public key. After a few tries to connect to the CVS, making mistakes before getting the right method, it seems that my account is blocked. With environment variables set like this : export CVSROOT=:ext:nvieville@cvs.rpmfusion.org:/cvs/nonfree export CVS_RSH=ssh Here's what "cvs co common" print: ssh_exchange_identification: Connection closed by remote host cvs [checkout aborted]: end of file from server (consult above messages if any) and if I try "ssh -v nvieville(a)cvs.rpmfusion.org" I get: OpenSSH_5.6p1, OpenSSL 1.0.0e-fips 6 Sep 2011 debug1: Reading configuration data /home/nico/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to cvs.rpmfusion.org [195.10.6.64] port 22. debug1: Connection established. debug1: identity file /home/nico/.ssh/id_rsa type 1 debug1: identity file /home/nico/.ssh/id_rsa-cert type -1 debug1: identity file /home/nico/.ssh/id_dsa type 2 debug1: identity file /home/nico/.ssh/id_dsa-cert type -1 ssh_exchange_identification: Connection closed by remote host To finish "ssh -v -i ~/.ssh/id_rsa nvieville(a)cvs.rpmfusion.org" gives : OpenSSH_5.6p1, OpenSSL 1.0.0e-fips 6 Sep 2011 debug1: Reading configuration data /home/nico/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to cvs.rpmfusion.org [195.10.6.64] port 22. debug1: Connection established. debug1: identity file /home/nico/.ssh/id_rsa type 1 debug1: identity file /home/nico/.ssh/id_rsa-cert type -1 ssh_exchange_identification: Connection closed by remote host So, I would be grateful if someone could unblock this situation, or could point me to the mistakes I've done. For information, if necessary, my actual IP and my login name on fas: 78.216.52.19 nvieville Thanks in advance for your response. Cordially, -- Nicolas Viéville
