Subject: ssh versions on unstable machines

Hi,

I cannot login on unstable 9x anymore, but can on 9s:

rmottola at login [login]:~ > ssh unstable9x
ssh_exchange_identification: Connection closed by remote host
rmottola at login [login]:~ > ssh unstable9s
Last login: Wed Jan 21 15:26:34 2026 from unstable10s.bo.
Sun Microsystems Inc.?? SunOS 5.9?????? Generic May 2002


I suppose unstable9x has an older ssh version or has some key exchange
