I am away from my office for the week. In Sacramento for the IEEE 802.1 interim meeting (for anyone in the neighborhood...). And I am working on SSH with my Centos install(s). 1) For right now I am using my XP drive with Tectia client. I have SSHed into my Centos server using password method and uploaded my public key and such. I see everything there. I think. I then delete all authentication methods but public key and am told that no recognized authentication match. When I add password back into my client, I get the password authentication method. My hunch is there is something I need to do with the SSH server config to access client certificate authentication? What do I need to do, and remember, all I have is a text window into my machine (can su) and I do not have my VI manual with me! (I will go and look for one online). 2) later this evening, I will pop in my Centos drive and then SSH from a Centos client. But of course my keys and such are on my XP drive. I know where Tectia keeps all of its keys, as I have moved them from one XP drive to another. Anyone know what I need to do? I do have a USB drive for the transfer. Or I can upload everything to my Centos server, then download to my Centos client. Thank you for your continued help. Oh, I have been going back into all of my threads here and pulling out notes on what to do to avoid asking something more than once.
