scp a remote file to a local machine

Posted by jpluimers on 2019/03/15

For me, scp is like tar; somehow I Google this every time…

  1. On the remote machine, find out the full path of the remote file: 
    ~ # ssh username@192.168.71.123
...
~ # ls -alh `find /vmfs/volumes/ | grep -w W81Entx64CI | grep '\.vmdk$'`
-rw-------    1 root     root      200.0G Aug 26 22:48 /vmfs/volumes/552f5788-33e30274-8dba-001f29022aed/VM/PSO/W81Entx64CI/W81Entx64CI-flat.vmdk
-rw-------    1 root     root         500 Aug 19 16:36 /vmfs/volumes/552f5788-33e30274-8dba-001f29022aed/VM/PSO/W81Entx64CI/W81Entx64CI.vmdk
  2. On the local machine, go to the right directory, then copy the file from the remote machine: 
    ~ # cd /vmfs/volumes/Samsung512NVME/PSO/VM/W81Entx64CI/
~ # time scp -v username@192.168.71.123:/vmfs/volumes/552f5788-33e30274-8dba-001f29022aed/PSO/W81Entx64CI/W81Entx64CI-flat.vmdk W81Entx64CI-flat.vmdk

 

I don't know what's worse--the fact that after 15 years of using tar I still can't keep the flags straight, or that after 15 years of technological advancement I'm still mucking with tar flags that were 15 years old when I started.

The last line will logon over ssh and shows the file transfer in a verbose way.

Requirements:

  • both machines have ssh
  • local machine has firewall entry to allow client ssh
  • remote machine has sshd and firewall entry to allow sshd server connections
