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.
|
||
|
|
|
||
|
|
Please note that '/' is used as host, path separator not ':' as you may
|
||
|
|
be used to, also '~' can be used to specify user HOME, but again after '/'
|
||
|
|
|
||
|
|
Example SRC_URI:
|
||
|
|
SRC_URI = "ssh://user@host.example.com/dir/path/file.txt"
|
||
|
|
SRC_URI = "ssh://user@host.example.com/~/file.txt"
