Top Forums UNIX for Advanced & Expert Users Connect direct - SFTP - List of servers that I can connect Post 303041452 by Chubler_XL on Sunday 24th of November 2019 03:39:11 PM

I believe IBM connect direct uses a proprietary protocol which is separate to and incompatible with SFTP.

Quote:
I was under the impression that SFTP will be successful between the servers only for which connect-direct is configured (atleast at server-level and not user-id level) between them.
SFTP runs over SSH and is used on thousands of systems around the world that don't have connect direct installed or configured.

Here are some answers to you specific numbered questions.
  1. SFTP is just a file transfer mechanism that runs over the SSH protocol. If you have SSH access to a computer you would normally also have SFTP access. If you have a password for an account on a remote computer that's running SSH and PasswordAuthentication is enabled (Servers can be configured to only allow public key authentication), and the User/Group is enabled for SSH access the you will be able to use SFTP. There is no file that lists all the servers you can access, but for each server you can check if password authentication is allowed and which users/groups have access.
  2. SFTP uses SSH for connection and transmission authentication can be configured to use password or public/private keys or both.
  3. What do you mean by refer? The starting directory for SFTP is configurable but defaults to the local account's home directory.
  4. Yes in the sshd_config on the target machine you can specify DenyUsers DenyGroups AllowUsers AllowGroups to control which accounts have access.
  5. direct connect uses it's own protocol which many have public/private keys but I would expect these would be separate to the SSH public/private keys.
