Set Mtime and Atime of symbolic link

[araneolus]

Hi,

Is it possible to create a remote symbolic link and set the atime and mtime to anohter time as the create time.
I have tried it with the SFTPEngine setAttributes method (SESTATUS) and the RemoteFile set Attributes method (FSESTATUS) but it doesn't work.
Perhapse it is not possible by the ssh Daemon ??

What part doesn't work? Do you get an exception? They're just ignored?

There is no error. I am able to create the symbolic link with
this.sftpClient.symlink(target, newLink);
and than set the file Attributes to the link with
this.sftpClient.getSFTPEngine().setAttributes(file,attrs);
The Values of FileAttributes are
[uid=0,gid=1001;atime=1663518244,mtime=1663518244]
and the file path is
/etc/letsencrypt/live/hupssotest.alfa-cloud.net/cert.pem
After this, the link has still the root uid, and root gid (uid=0,gid=0)
lrwxrwxrwx 1 root root 49 Sep 18 18:58 cert.pem -> ../../archive/hupssotest.alfa-cloud.net/cert8.pem
There are no exception during execution.
It is the same, if I execute a chmod to the link without the '-h' option at linux.

I have also tried to override the setAttributes funktion with FSETSTAT, without success :-(

    public void setAttributes(String path, FileAttributes attrs)
            throws IOException {
        doRequest(
                newRequest(PacketType.FSETSTAT).putString(path, sub.getRemoteCharset()).putFileAttributes(attrs)
        ).ensureStatusPacketIsOK();
    }
