Goldstein Lyor reassigned SSHD-753:

    Assignee: Goldstein Lyor

> SSHD cannot read its keyfile through a symlink
> ----------------------------------------------
>                 Key: SSHD-753
>                 URL: https://issues.apache.org/jira/browse/SSHD-753
>             Project: MINA SSHD
>          Issue Type: Bug
>    Affects Versions: 1.5.0
>            Reporter: Anthony Wood
>            Assignee: Goldstein Lyor
> In {{AbstractGeneratorHostKeyProvider.loadFromFile()}} the configured {{keyPath}} is
checked using {{LinkOption.NOFOLLOW_LINKS}}.  If the path is a symlink, the key will be ignored.
 Perversely, this class then generates and writes out a new key (if overwriteAllowed) writing
through the symlink and clobbering the original; on every startup it will ignore its own previous
key and do it again.
> Note this is *not* about following or listing symlinks for, e.g., SFTP clients (SSHD-733).
> Since the key path is purely server-side configuration, SSHD should not interfere with
deployment details such as whether its private key is behind a symlink.
