Need to combine “Sudo” and “ScpTo” examples of JSch

问题

I'm unsuccessful with combining "Sudo" and "ScpTo" cases.

I noticed, that both work through "exec" channel.

Clean "ScpTo" case finishes with "Permission denied" message.

"Sudo" case

Channel channel = session.openChannel("exec");
((ChannelExec) channel).setCommand("sudo -S -u <supervisor> whoami");

works fine.

When I connect to my server through FarManager I write server option:

sudo su -l <supervisor> -c /usr/libexec/openssh/sftp-server

Also, I can run usual SFTP client like this:

sftp -s 'sudo su -l <supervisor> -c /usr/libexec/openssh/sftp-server'  "usual user"@"host"

and give put command.

But such option (-s) is not implemented in JSch.

How can I configure my case (Sudo & ScpTo) with JSch?

回答1:

In ScpTo.java example, there's this code:

String command="scp " + (ptimestamp ? "-p" :"") +" -t "+rfile;

Change that to:

String command="sudo su -l <supervisor> -c scp " + (ptimestamp ? "-p" :"") +" -t "+rfile;
