Receive files from remote device (scp)
How to copy files to or from a remote device
Sometimes a workflow demands to receive files from a remote edge device like a Raspberry Pi. One example could be a log file that needs further analysis. Alternatively, you might need to copy a file to the device. When the device is not in the same local network and behind a firewall this can be a lot of hassle. In this example we will show you a workflow which uses qbee-connect to download the syslog file from a remote device. This gives you a simple solution to transfer files from an edge device or to an edge device and it also helps you to debug.
qbee allows you to work with files on remote devices in a few different ways. These are:
- file distribution through the integrated file manager: This works from the system to the edge device and applies full configuration management principles
- remote two-way file access through
scpas described in this guide
- remote two-way file and folder syncronization with
rsyncas described here
- remote file browsing capabilities with
sshfsas described here
Task - download remote syslog file
- open qbee-connect on your machine and connect to the remote device with ssh on port 22
- qbee-connect maps
port 22on a different
localhost port. In this case it is
- run a
scpcommand from your local machine to the remote device using the
-Pcommand to use the mapped port
scp -P 62530 root@localhost:/var/log/syslog syslog_ctr-700
- this copies the remote syslog file to the local device
- task completed. This works also across firewalls or NATs.
If you are on Windows and want a graphical UI you can also look at the free tool WinSCP. This allows to do the whole process graphically.
Please configure it like this. The port is the port mapped by qbee-connect.
Then you will have full access to the remote file system:
This works of course in both directions and is just another example how you can use the port mapping functionality of qbee to achieve a simple file transfer. Here is a short remote file transfer video showing the above.
