How do I transfer a file from my local machine to a remote host to which I need to get through a jump host? These are the steps I follow to connect to the remote host
1. ssh myname@jump-host
2. enter password
3. sudo su - another-random-name
4. ssh name@remote-host
Now I want to transfer a file from my local machine to the remote-host. How would I achieve this? I have already tried scp -oProxyCommand but I don't quite know where I should include step 3 as part of this command?
回答1:
Use port forwarding to get third host ssh port on your localhost, in this way:
ssh -L 2222:remote-host:22 myname@jump-host
then (on another tab/shell on first host):
scp -P 2222 file myname@localhost:
will copy directly to remote host.
回答2:
On the jump host under another-random-name run
ssh -L 2222:remote-host:22 myname@jump-host
then on your local computer you can run
scp -P 2222 file name@jump-host:
SCP will try to connect to jump-host, while in fact this connection will be forwarded to jump-host. And will use name as it is connecting to remote-host.
You are probably still facing problem with certificate for another-random-user. You can either create certificate on your machine for your-local-user and put public key on remote-host in user allowed keys.
