Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Assume

  • Single server
  • One account to access the server (ssh), authentication based on PPK
  • Multiple clients

What is the good practice

  • Configure for each different client an additional key
  • copy the private key from one client to another

Are there any other approaches ?

Why the requirement for a single account? This is usually a very bad idea, as you have no way of doing any form of audit or accountability logging. –  growse Nov 10 '11 at 12:57
    
Private keys should never be generated by anyone/anything but the user themselves. –  EEAA Nov 10 '11 at 14:04
    
@growse: Why a single account - this is the use case. I'm working for multiple customers. Each of these customers require that I use their workstation setup (so I'm switching machines a lot). Still I need to be able to access my machine. –  Francis Martens Nov 11 '11 at 8:29
