Dear Maintainer,

According to the changelog entry for 1.3.8.b+dfsg-3, mod_delay, mod_ls, mod_xfer should be in core modules, but they aren't.

Trixie box :
$ > proftpd -l
Compiled-in modules:
  mod_core.c
  mod_rlimit.c
  mod_auth_unix.c
  mod_auth_file.c
  mod_auth.c
  mod_log.c
  mod_site.c
  mod_facts.c
  mod_dso.c
  mod_auth_pam.c
  mod_cap.c
  mod_ctrls.c
  mod_lang.c

Bullseye box :
$ > proftpd -l
Compiled-in modules:
  mod_core.c
  mod_xfer.c
  mod_rlimit.c
  mod_auth_unix.c
  mod_auth_file.c
  mod_auth.c
  mod_ls.c
  mod_log.c
  mod_site.c
  mod_delay.c
  mod_facts.c
  mod_dso.c
  mod_auth_pam.c
  mod_cap.c
  mod_ctrls.c
  mod_lang.c

This causes some config directives to make proftpd fail to start. For example : TimeoutNoTransfer, TimeoutStalled
I suppose there is also missing runtime functionality, but I didn't test further.

Hello Sylvain,

I guess there is some misunderstanding. The command "proftpd -l"
lists the modules / features, which could be built as modules, but
are actually built into the proftp binary. The changelog says, that
the 3 features were moved out of the binary into modules files, which
are packaged in the Debian package, see [1].

So you just have to load them and the needed features are there.  And
yes, you are right: I could have added the "LoadModule xxxx"
statements into the /etc/proftpd/modules.conf file to make sure the
features are available, even after the upgrade (users may later
disable them).

Let me know, if I should implement this.
