I have accounts on two Centos servers, A and B, each hosted on a remote VPS by a different provider/datacenter.
Until yesterday night, I could connect without problems via SSH to both servers from my home Fedora 16 desktop.
Yesterday I completed (fingers crossed) the switch to a different ADSL provider. From the moment I turned on the modem on the new ADSL line, I became unable to ssh into server A. All attempts abort with this message:
ssh_exchange_identification: Connection closed by remote host
<snip> This would be obnoxious, but have you checked with your ADSL provider, to see if they're blocking ssh traffic?

Also. Could the server A have a firewall that had allow ranges for your original ip range? Or denyhosts... something like that
