Hey, I just need to clarify something as I have been testing this and seems to be true using OpenSSH 2.9p2. It seems you cannot do an SSH version 2 protocol (ssh -2 ...) to establish authentication when using RSA version 1 keys (ssh-keygen -t rsa1 ...). Is this the case? If not, are there any specific sshd or ssh config options that allow one to usa RSA1 keys to establish an SSH2 authenticated session. Thanks. __________________________________ Raymond T Sundland Internet Security Analyst Internet Infrastructure & Security Group E-commerce Strategy & Delivery Email: [EMAIL PROTECTED] __________________________________ Merck-Medco Managed Care L.L.C. http://www.merckmedco.com/ <http://www.merckmedco.com/>
