Example sshd_config file has bad path to sftp-server. Should be /usr/lib/openssh/sftp-server, not /usr/libexec/openssh/sftp-server

[Paul Mackinney]

Silly error, can't believe it wasn't found or reported earlier.

SFTP wasn't working, auth.log showed "cannot stat /usr/libexec/openssh/sftp-server: No such file or directory"

I checked /etc/ssh/sshd_config and /usr/share/doc/openssh-server/examples/sshd_config, which is apparently the source file. Both had the "libexec" path to the file.

I ran "locate openssh/sftp-server" and got "/usr/lib/openssh/sftp-server"

Corrected the path in the config file & all was well.

This is peculiar, because I don't believe we've ever written it out with the upstream libexec path. Yes, the examples file shows it as libexec, but we've written out "Subsystem sftp /usr/lib/openssh/sftp-server" for new installations since 2005.

Is it possible that you had hand-edited your sshd_config at some point?

[Paul Mackinney (sq-paul)]

Yes, I'm certain that I hand-edited the file, feel free to close the bug. I
_assumed_ that the example file would be correct for the installed package,
silly me.

Cheers,

Paul

OK, thanks. I've just pushed a patch to fix up the "Subsystem sftp" line in the example sshd_config file, too.

[Launchpad Janitor (janitor)]

This bug was fixed in the package openssh - 1:7.1p1-3

---------------
openssh (1:7.1p1-3) unstable; urgency=medium

  * Drop priority of openssh-client-ssh1 to extra (closes: #807518).
  * Redirect regression test input from /dev/zero, since otherwise conch
    will immediately send EOF.
