This is possible with many Unix boxes (just tested it on Debian Linux with OpenSSH), but requires some changes to 'sudo' configuration files. It mostly deals with sftp, although the same applies to scp as well. We already investigated a similar scenario several years ago, so I'm sharing our findings here.

If you can, please send us a communication log from WinScp - if we knew exactly which commands you issue there, we would be able to let you know how to reproduce the same with Rebex libraries. Instead, you have to open an SshChannel and use RequestExec, but more on that below. To make this work, you would have to start the scp command in the same session where you executed 'sudo su USER' (perhaps you are doing something like this in WinSCP), but this is not going to work with Scripting sessions because those have a pseudo-terminal allocated, which would interfere with SCP traffic. Even though both sessions run over the same SSH connection, they are distinct. The sudo su USER command only affects the scripting session, not the SCP session you established later. Unfortunately, this approach is not going to work.

Any ideas what I am doing wrong? Note that I am able to do basically the same thing using WinSCP, so it is not a server configuration / password issue.Īny help would be greatly appreciated. I have played with this for awhile and tried a number of different combinations of the above with the same results. Scp.GetFile(remotePath, localPath) // Permission failure. Var response = scripting.ReadUntilPrompt() Var scripting = ssh.StartScripting('sudo su USER') Then I am binding the ssh session to a SCP object and attempting the file transfer. I am creating a SSH session, logging in, executing my 'sudo su USER' command and executing a whoami to confirm the login change. I need to login with one set of credentials and then change to another set to access the file I need.Īpparently, this is not supported by SFTP, so I am using SCP instead.

I am trying to download a file on a server.
