Is it possible to upload/download files using the serial console ?

Thu Jun 09, 2022 1:52 pm

Hello,

Is it possible to dowload/upload backup files using the serial console port (RJ45 port) ?
And if it is possible, how can this be achieved ?

Thank you in advance!

Not, the serial is just for terminal debug, but you can launch /export command and save the results.

Only the RouterBoot firmware... Been there, tried that, I was trying reload the entire OS. RouterOS has to come from the Ethernet port..

Otherwise it is similar to using the keyboard and monitor to transfer a file on Windows.. You can't. You use your keyboard and monitor to tell Windows to transfer a file.

Yeah, ROS console is really missing simple zmodem/xmodem download/upload functionality, for getting backups, certificates and other files to/from device with just serial port.
Currently this is not possible.
Only way to transfer files over serial is to set up PPP connection over it instead of console. Then you can run IP and winbox or SSH/SFTP over it.

nowadays is not only about enabling a feature, is about not creating a security risk with it

If someone has access to the console port of your device, you have already lost all security..

I have a dead RouterBoard because I can only transfer RouterBoot using XModem, it won't accept RouterOS using XModem.

Interesting.. I didn't know this was possible.. May need to try it, just to know that it works and I can say I did it... ;)

If you can upload RouterBoot via serial, you should be able to install RouterOS using Netinstall. But if the single Netinstall-capable Ethernet port is dead, it's the end of all hopes for the Routerboard.

PPP over serial works but you need a running RouterOS to configure it, and the serial port can either work as a console or for PPP, so if Ethernets and wireless are all broken, you'd need an USB hub with two serial adaptors to have a serial console access together with PPP (or a multi-channel USB to serial adaptor, it also works fine).

Yes... In troubleshooting the dead Ethernet port, I tried to reinstall RouterOS.. That is when I discovered that while RouterBoot accepts XModem transfers, it is ONLY for RouterBoot, it will not work for RouterOS too.. Wasted a lot of hours transferring RouterOS using XModem having it fail at the end.
