Version: 3.0.5-0.3
Severity: normal
Tags: upstream

Dear Maintainer,
Problem:
The vsftpd.conf man page in Debian (package vsftpd 3.0.5-0.3) states that both
"max_clients" and "max_per_ip" have a default value of "0 (unlimited)".
However, according to the source code in "tunables.c", the compiled-in defaults
are actually 2000 for "max_clients" and 50 for "max_per_ip".
[ man 5 vsftpd.conf ]
> max_clients
> If vsftpd is in standalone mode, this is the maximum number of
> clients which may be connected. Any additional clients connect‐
> ing will get an error message.
>
> Default: 0 (unlimited)
> max_per_ip
> If vsftpd is in standalone mode, this is the maximum number of
> clients which may be connected from the same source internet ad‐
> dress. A client will get an error message if they go over this
> limit.
>
> Default: 0 (unlimited)
Details:
In the source file "tunables.c", these lines define the built-in defaults:
> tunable_max_clients = 2000;
> tunable_max_per_ip = 50;
Historical reference:
According to the upstream changelog (vsftpd-2.2.0pre2), the defaults were
explicitly changed to 2000 / 50:
security.appspot.com/vsftpd/Changelog.txt
https://security.appspot.com/vsftpd/Changelog.txt
> (vsftpd-2.2.0pre2)
> - Revert listen to be "NO" by default and also set max_per_ip / max_clients
> to 2000 / 50 as a default. Thanks to Solar.
