The clients scp command starts an ssh session and passes<br class="">along an scp command to be executed on the server's end. On a<br class="">Unix-like system the server would execute the scp command as a<br class="">separate process, but on OVMS I have implemented the scp protocol<br class="">within console_ssh.<br class=""><br class="">So, for example, I can use scp to fetch my startup script so I can<br class="">edit it to remove the extra command I added to set the logging level<br class="">for ssh while I was debugging and then write back the updated script:<br class=""><br class="">auge1224> scp -r ovms:/store/events .<br class="">startmeup 100% 72 0.1KB/s 00:00<br class="">auge1225> scp events/system.start/startmeup ovms:/store/events/system.start/<br class="">startmeup 100% 56 0.1KB/s 00:00<br class="">auge1226><br class=""><br class="">In these examples you see that I am using public key authentication so<br class="">I don't have to enter a password. Secure and very convenient!<br class=""><br class="">The SSH implementation is a bit slow doing the public key calculations<br class="">so there is a pause of a few seconds as each command begins, but then<br class="">the files are transmitted expediously. I have not attempted yet to do<br class="">tuning of build options for wolfssh for speed and memory usage. I<br class="">have also not figured out yet how to perform the rekeying procedure<br class="">with this wolfssh library. Because the rekeying is not implemented<br class="">properly some data may be lost when it occurs. However, rekeying will<br class="">be triggered after about 1GB of data transfer, so it seems unlikely<br class="">that we will hit that trigger right away.<br class=""><br class="">For those who have been wondering when this would be completed, sorry<br class="">for the delay. The scp protocol is somewhat crude and there is no<br class="">document to specify it which meant I had to do experiments to figure<br class="">out the right actions at each step. Finally I found the OpenSSH<br class="">implementation on github so I could RTSL. After that testing all the<br class="">corner cases took a while. I'm sure you all will let me know if you<br class="">find problems!<br class=""><br class=""> -- Steve<br class="">_______________________________________________<br class="">OvmsDev mailing list<br class=""><a href="mailto:OvmsDev@lists.teslaclub.hk" class="">OvmsDev@lists.teslaclub.hk</a><br class="">http://lists.teslaclub.hk/mailman/listinfo/ovmsdev<br class=""></div></div></blockquote></div><br class=""></div></body></html>
