So I installed the inotify-tools package.  I still get
the

File notification error: No file notification program found on /ssh:root@fs2:

message, though.

But automatic refresh of dired buffers in tramp does
now work.

What about those messages?

Ciao; Gregor

Did you restart Emacs, in order to avoid stale caches?

Hmm.

They tell you to run Tramp with tramp-verbose 6, and to send the Tramp
debug buffer. Preferred directly to me, in order not to clog the mailing
list.

As usual, start with

--8<---------------cut here---------------start------------->8---
# emacs -Q --eval '(setq tramp-verbose 6)'
--8<---------------cut here---------------end--------------->8---

Tramp: needs file notification program on remote machine, what to install?

[Gregor Zattler]

Hello, I'm visiting a directory which is under version
control (git) on a remote machine (still debian/buster)
and get the following error:

Tramp: Opening connection nil for root@fs2 using ssh...done
File notification error: No file notification program found on /ssh:root@fs2:

While I can work with the files there the message is
shown all the time and is at least annoying, and file
notification might be useful.  But I did not find what
to do in the fine manual.

I assume I should instal a helper program on the remote
machine, but AFAIK there are several file system change
notifiers.  Does anyone know which is best/easiest for
tramp?

Thanks, Gregor

Tramp supports "inotifywait" and "gio monitor" calls on the remote side.
