them.

## SSH keys: `keyfunc ssh`

@@ -100,24 +94,22 @@ Adds the `pub` line to `~/.ssh/authorized_keys` on the host. No command is run
|
||||
on the host: the file is fetched, changed here, and written back with the
|
||||
system `sftp` client in batch mode.
|
||||
|
||||
The first connection lists `~/.ssh` and then fetches
|
||||
`~/.ssh/authorized_keys` from it. The file reads as empty in two cases only:
|
||||
`sftp` reported `~/.ssh` itself as not being there, or the listing came up and
|
||||
the file was not in it. Any other outcome of that connection fails the run — a
|
||||
`~/.ssh` that is there but cannot be entered, an `authorized_keys` that is there
|
||||
but cannot be read, or a connection that did not come up — and the tool prints
|
||||
what `sftp` said and exits with status 1 without writing anything, rather than
|
||||
put a file back holding the new key alone. The listing is what tells a missing
|
||||
directory from one shut to the user, which `sftp` reports on a fetch the same
|
||||
way; the wording of a missing file elsewhere does not count either, since `ssh`
|
||||
writes `No such file or directory` about an `-i` it cannot find on a session
|
||||
that then authenticates through the agent. If an identical line is already in
|
||||
the file, the tool prints `already present` and connects no further. Otherwise
|
||||
the line is added (after a newline, if the file did not end with one) and a
|
||||
second connection:
|
||||
The first connection fetches `~/.ssh/authorized_keys`. The file reads as empty
|
||||
only when `sftp` reported that file as not being there — the one line naming
|
||||
that path. The same wording anywhere else in the session does not count: `ssh`
|
||||
writes `No such file or directory` about an `-i` it cannot find, on a session
|
||||
that then authenticates through the agent. When `sftp` failed for any other
|
||||
reason — the file is there and cannot be read, the connection did not come up —
|
||||
the tool prints what `sftp` said and exits with status 1 without writing
|
||||
anything, rather than put a file back holding the new key alone. What `sftp`
|
||||
cannot tell apart is a missing file and one in a directory it cannot enter, so a
|
||||
`~/.ssh` whose mode shuts the user out reads as a host with no file; the second
|
||||
connection sets that mode to `0700` and writes, as on a host that has none. If

an identical line is already in the file, the tool prints
