Subject: [PATCH 456/557] ssh: log the libssh2 error message when ssh session
|
|
startup fails
|
|
|
|
When a ssh session startup fails, it is useful to know why it has
|
|
failed. This commit changes the message from:
|
|
"Failure establishing ssh session"
|
|
to something like this, for example:
|
|
"Failure establishing ssh session: -5, Unable to exchange encryption keys"
|
|
|
|
Closes #3481
