This depends which tools are installed on the client device / supported by the kernel.
Possible methods for file transfer (unordered):
netcat or socat or with bash and /dev/tcpwget or curl from a web serverRead Simple file transfer and How to get file to a host when all you have is a serial console? for more possibilites.
desktop.jpg from the device to your pc with the netcat/nc method:On your pc, disable temporarily (or reconfigure if possible) any firewall and run
and on the device
where you need to replace A.B.C.D with the IP address of your pc.As soon as the transfer was successful, the netcat process on your pc should stop automatically. If not, something is wrong and you can stop it with Ctrl+C
For the other direction, just exchange < and > on both sides. Make first a backup of the original desktop.jpg (cp desktop.jpg desktop_orig.jpg).
I have no ssh or ftp(or etc) on the device.
So, I do next:
telnet a.b.c.d tee telnet.logcat file.txttelnet.log from trashIt should be easy to write utility to download/upload file over telnet
Try with rcp command.
Use man rcp for more information in case you want to automate transfers.
By the way, you do know this is very insecure, right?
@jofel and all others, Thank you very much for your kind assistance. I think device has a customized os installed as it recognized some specific linux commands only. netcat is not recognized by the device. However today I got success to transfer the file using tftp command. I successfully replaced desktop.jpg file with this command. What I did is, created tftp server on window system. login via telnet on device and run these commands:
download filetftp -l -p tftp -l desktop.jpg - 192.168.0.249 69
Standard ahci 10 serial ata controller driver 2017. As of March 2014, the current version of the specification is 1.3.1. AHCI is separate from the SATA 3 Gbit/s standard, although it exposes SATA's advanced capabilities (such as and ) such that host systems can utilize them. The specification describes a system memory structure for computer hardware vendors to exchange data between host system and attached. AHCI gives software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters.
upload filetftp -l desktop.jpg -g 192.168.0.249 69
I have done this now by these methods:
Create ftp server (by installing solerwinds) on window system. login via telnet on device and run these commands:
To download a file:
Example:
or to upload file:
Example:
default location of tftp file is C:TFTP-Root
I just uploaded a ~7 Kb firmware file to a BusyBox based Linux embedded system over the serial port.
No networking, no file transfer utilities; no Base64 utils or anything remotely useful on the device.
On the host, I trivially encoded a firmware into the following format; a kind of hex-dump consisting of shell literals combined with printf commands:
basically shell printf commands with x escape sequences that printf interprets. On the device I did:
then used the minicom's ASCII file send (Ctrl-AS) to send this file to the host. I could just have used copy and paste, since the amount of data is small.
Then, marked executable and ran the printf script:
Checked using BusyBox's md5sum that the firmware.bin checksum on the device matches the original firmware image on the host.
P.S. The shell double quote syntax passes through x verbatim because it's not a recognized escape sequence; hence we don't have to double up the backslashes.
I use the following method to download small binary files via telnet into my windows box:
