Kevin K's questions

I am looking for a versioning file system like VMS used to have. Are there any modern equivalents I can host for Windows clients? Requirements:

• Ability to map a drive to the shared file system from XP, Vista, Win7, Samba (Linux)

• Ability to host this file system either on a Windows Flavor, or CentOS

• Completey transparent to the end users - looks like a normal drive / share. I am sure I could hack something together with something like SVN, but it would not be transparent.

I have searched Google, and here and found nothing so far.

I need to automate a way to distribute files to many servers. The problem of course is I need to use a secure protocol (SSH or SCP) and the username / password on each server is different.

The scenario is we have a master server a, with user a_prod and we need to send updated scripts / configs, etc. to servers b, c, d, ... and on these servers the usernames are say b_dev, c_test, d_prod with each having unique passwords.

The usernames need to be unique across environments for a few reasons, dealing with DB2 and corporate security.

Shared keys will not work in this scenario, so I need to pass the usernames and passwords via a script. It is an AIX environment, and I do not have the ability to install expect.

Any ideas?

Shared keys are mentioned in multiple responses below: I have tried a few ways to do this, I think the main issue is the remote user ID's do not exist on any other host, so I can not do an ssh-keygen for them on the host I want to ssh from to do a shared key implementation with the main user (a_prod) having multiple identities depending upon the target host (b_dev, c_test_d_prod). The private key for these users needs to be generated on host a for the remote users, and then their public keys need to be copied to the target hosts.
