BitBake 'Fetch' implementations
|
||
|
|
|
||
|
|
This implementation is for Secure Shell (SSH), and attempts to comply with the
|
||
|
|
IETF secsh internet draft:
|
||
|
|
http://tools.ietf.org/wg/secsh/draft-ietf-secsh-scp-sftp-ssh-uri/
|
||
|
|
|
||
|
|
Currently does not support the sftp parameters, as this uses scp
|
||
|
|
Also does not support the 'fingerprint' connection parameter.
