COPY file from one server to another

ssh cp scp

Looks like your prod server can't reach the dev server (on ssh). I assume you can reach both from your workstation. You can use scp 3 hosts copy, which copies between hosts using a 3rd one (in your case prod05 -> workstation -> dev 01). Of course it's not the fastest way to copy, both perfect when you have to copy once and you have firewall issues.

Run the following on your workstation (where you can reach both):

scp -3 prod05:/tmp/sbg.snappy [email protected]:/tmp

From the man page of scp:

 -3      Copies between two remote hosts are transferred through the local host.
         Without this option the data is copied directly between the two
         remote hosts.  Note that this option disables the progress meter.

I have to get some files from production to DEV server. SCP command gives the timeout.

I do not have ip and I connect to the server using ssh command as below.
```
ssh [email protected]
sudo -u xxx_bio_xxx -i
```

  If scp is giving Timeout , first that has to be fixed! Check ConnectTimeout parameter in ssh config! It could also be that the remote server is not reachable.

  Can you specify more? Where you start the scp command, on the prod server or on the dev server? (please copy&paste the ommand as well) And when it gives you timeout? It can not start the copy or starts the copy, but runs into timeout later?

  @komz OS Name- cat /proc/version , run this command: scp -vvv /tmp/sbg.snappy [email protected]:/tmp, this will give info about the problem. Update the Question with these outputs.

  Also run ping <dev_server_ip> command from prod to the other server! This would tell you about the connectivity!

  scp is based on SSH, that would mean that you could not even connect by SSH, are you able?

If scp is giving Timeout , first that has to be fixed! As man rsync says For remote transfers, a modern rsync uses ssh for its communications unless otherwise modified. So ConnectTimeout parameter is critical. It could also be that the remote host is not reachable. Its just not that the scp failed but rsync is going to work.
