[Buildroot] vsftpd

[Buildroot] vsftpd

[Charles Krinke]

its my day to be a "noob" again as I am having trouble getting vsftpd
accepting connections on an MPC8321 project. I am near the end of my
project after a year and started with buildroot 2011.03 last spring
and today is the day to enable vsftpd and ntp-wait.

I enable the vsftpd package, it builds, and I get a /usr/sbin/vsftpd
and /etc/init.d/S70vsftpd on the MPC8321 target. When the target
boots, it does say "Starting vsftpd: OK" on the console.

The package does not create an /etc/vsftpd.conf, so I created one that
looks like this:

# cat /etc/vsftpd.conf
anonymous_enable=YES
anon_root=/home/econolite
local_enable=YES
#

Now for the bad news. Connections are refused from an external host,
making me think vsftpd is not really running. A "ps" does not show
vftpd in its list. A "netstat" does not show ftp. Invoking vsftpd from
a bash prompt says:

# vsftpd
500 OOPS: vsftpd: not configured for standalone, must be started from inetd
#

So, can someone help me navigate through the "Valley of Confusion"
towards the "Ridge of Enlightment" so I can get to the next problem
which is "why the frick cannot I get microperl to compile".

Do we have inetd/xinetd? Can't find them. http://en.wikipedia.org/wiki/Xinetd seems to be unsupported. What is the modern way of running daemons on demand-?

By the way, I have trouble compiling vsftpd at least with the latest linaro toolchain (haven't tried other toolchains so far):

Busybox has an inetd applet, but we don't have any of the standalone
versions, if that's what you mean.

It works here with the default internal arm toolchain, but I haven't

Dear Yegor:

I would also suggest trying the default arm toolchain in busybox and
seeing if it compiles vsftpd. Personally, I am currently using
CodeSourcery's toolchain for a glibc build this week and recommend
them for an external toolchain. I also have not used Linaros toolchain
at all.

[Buildroot] vsftpd

[Markus Königshaus]

You forget to set listen to YES, I thing - look at man vsftpd.conf:

[ ... ]

   listen If  enabled,  vsftpd will run in standalone mode. This means
that vsftpd must not be run from an inetd of some kind. Instead, the
vsftpd executable is run once directly. vsftpd itself will then take care of
              listening for and handling incoming connections.

              Default: NO

[Buildroot] vsftpd

[Charles Krinke]

Dear Markus:

This helps, thank you. Adding "listen=YES" to the /etc/vsftpd.conf
file gets from 'connection refused' to:

ckrinke at hwa:~$ ftp 10.1.15.129
Connected to 10.1.15.129.
500 OOPS: vsftpd: cannot locate user specified in 'ftp_username':ftp
ftp> quit
ckrinke at hwa:~$ ftp rude at 10.1.15.129
ftp: rude at 10.1.15.129: Name or service not knownftp>
ftp>
ftp>

Would you mind getting this "Noob for the Day" to the next step? That
is, I would expect users that exist on the PPC target to be valid ftp
users. I did "RTFM" man vsftpd.conf but missed the importance of
listen. I also dont see ftp_username in the man page, so my
understanding if a bit better, but still incomplete.

[Buildroot] vsftpd

[Markus Königshaus]

Look at the example config file, I think, you need to tell vsftpd witch
users are allowed to login (without comments):

local_enable=YES
local_umask=022
userlist_deny=NO
userlist_enable=YES
userlist_file=/etc/vsftpd.user_list

and

secure_chroot_dir=/var/empty (or something equal, must exists, must be
empty)

In /etc/vsftpd.user_list put the system - users, you want to allow for
login, the users must exists. Use the user's password for login.

As an alternate you can enable anonymous logins with
"anonymous_enable=YES" and setting "ftp_username" to a system - user you
want to use for anonymous logins.

[Buildroot] vsftpd

[Charles Krinke]

Thank you kindly, Markus. I now have vsftpd accepting connections and
navigating directories on my MPC8321 target using buildroot. The key
was the config files that were missing. Once they had appropriate
entries as you described, everything works.

A "ps" shows vsftpd. A "netstate" shows ftp as a consequence of the
"listen=YES" statement. The rest was user configuration as described.

We can close this part of the thread and see if we can help Yegor with
his ARM compilation of vsftpd.

Charles "Noob for the Day" Krinke

p.s. Microperl next. But I will start a new thread.

Since you solved your problem, could you submit a patch to Buildroot so
that the vsftpd package installs at least a basic and minimally working
vsftpd.conf configuration file? It's better if such packages work
outside of the box with a minimal configuration.

Thanks!

Dear Thomas:

I will. Basically, I need to download the latest buildroot in a
seperate directory on my laptop, build the vsftp and other packages
and put a patch together. I need a bit of time, but will work on this
in the background to help move it forward.

I found the problem. See this post: https://www.lonelycoder.com/redmine/boards/7/topics/531

To link against SSL you need both -lssl and -lcrypto. This info can be also found in output/build/vsftpd-2.3.5/vsf_findlibs.sh
