Server 18.04 and vstfpd

If someone would have some guidance on what might be my problem I would appreciate it very much. I have a fresh install of ubuntu server 18.04 running in esxi 6.5. Vmtools installed and all the updates done to the server. I installed vstfpd and when I transfer files via filezilla to it the server is hit and miss. When I say hit or miss the vm will lock up and sometimes it will not. Not sure if the guide I followed will help any but I followed it to a T except for me trying to trouble shoot and changed the pam_service_name=vsftpd to pam_service_name=ftp and then un-commented out the following

Uncomment this to enable any form of FTP write command.

write_enable=YES
Below is the vsftpd.conf

Example config file /etc/vsftpd.conf

The default compiled in settings are fairly paranoid. This sample file

loosens things up a bit, to make the ftp daemon more usable.

Please see vsftpd.conf.5 for all compiled in defaults.

READ THIS: This example file is NOT an exhaustive list of vsftpd options.

Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd’s

capabilities.

Run standalone? vsftpd can run either from an inetd or as a standalone

daemon started from an initscript.

listen=NO

This directive enables listening on IPv6 sockets. By default, listening

on the IPv6 “any” address (::slight_smile: will accept connections from both IPv6

and IPv4 clients. It is not necessary to listen on both IPv4 and IPv6

sockets. If you want that (perhaps because you want to listen on specific

addresses) then you must run two copies of vsftpd with two configuration

files.

listen_ipv6=YES

Allow anonymous FTP? (Disabled by default).

anonymous_enable=NO

Uncomment this to allow local users to log in.

local_enable=YES

Uncomment this to enable any form of FTP write command.

write_enable=YES

Default umask for local users is 077. You may wish to change this to 022,

if your users expect that (022 is used by most other ftpd’s)

#local_umask=022

Uncomment this to allow the anonymous FTP user to upload files. This only

has an effect if the above global write enable is activated. Also, you will

obviously need to create a directory writable by the FTP user.

#anon_upload_enable=YES

Uncomment this if you want the anonymous FTP user to be able to create

new directories.

#anon_mkdir_write_enable=YES

Activate directory messages - messages given to remote users when they

go into a certain directory.

dirmessage_enable=YES

If enabled, vsftpd will display directory listings with the time

in your local time zone. The default is to display GMT. The

times returned by the MDTM FTP command are also affected by this

option.

use_localtime=YES

Activate logging of uploads/downloads.

xferlog_enable=YES

Make sure PORT transfer connections originate from port 20 (ftp-data).

connect_from_port_20=YES

If you want, you can arrange for uploaded anonymous files to be owned by

a different user. Note! Using “root” for uploaded files is not

recommended!

#chown_uploads=YES
#chown_username=whoever

You may override where the log file goes if you like. The default is shown

below.

#xferlog_file=/var/log/vsftpd.log

If you want, you can have your log file in standard ftpd xferlog format.

Note that the default log file location is /var/log/xferlog in this case.

#xferlog_std_format=YES

You may change the default value for timing out an idle session.

#idle_session_timeout=600

You may change the default value for timing out a data connection.

#data_connection_timeout=120

It is recommended that you define on your system a unique user which the

ftp server can use as a totally isolated and unprivileged user.

#nopriv_user=ftpsecure

Enable this and the server will recognise asynchronous ABOR requests. Not

recommended for security (the code is non-trivial). Not enabling it,

however, may confuse older FTP clients.

#async_abor_enable=YES

By default the server will pretend to allow ASCII mode but in fact ignore

the request. Turn on the below options to have the server actually do ASCII

mangling on files when in ASCII mode.

Beware that on some FTP servers, ASCII support allows a denial of service

attack (DoS) via the command “SIZE /big/file” in ASCII mode. vsftpd

predicted this attack and has always been safe, reporting the size of the

raw file.

ASCII mangling is a horrible feature of the protocol.

#ascii_upload_enable=YES
#ascii_download_enable=YES

You may fully customise the login banner string:

#ftpd_banner=Welcome to blah FTP service.

You may specify a file of disallowed anonymous e-mail addresses. Apparently

useful for combatting certain DoS attacks.

#deny_email_enable=YES

(default follows)

#banned_email_file=/etc/vsftpd.banned_emails

You may restrict local users to their home directories. See the FAQ for

the possible risks in this before using chroot_local_user or

chroot_list_enable below.

chroot_local_user=YES
user_sub_token=$USER
local_root=/home/$USER/ftp
pasv_min_port=40000
pasv_max_port=50000
userlist_enable=YES
userlist_file=/etc/vsftpd.userlist
userlist_deny=NO

You may specify an explicit list of local users to chroot() to their home

directory. If chroot_local_user is YES, then this list becomes a list of

users to NOT chroot().

(Warning! chroot’ing can be very dangerous. If using chroot, make sure that

the user does not have write access to the top level directory within the

chroot)

#chroot_local_user=YES
#chroot_list_enable=YES

(default follows)

#chroot_list_file=/etc/vsftpd.chroot_list

You may activate the “-R” option to the builtin ls. This is disabled by

default to avoid remote users being able to cause excessive I/O on large

sites. However, some broken FTP clients such as “ncftp” and “mirror” assume

the presence of the “-R” option, so there is a strong case for enabling it.

#ls_recurse_enable=YES

Customization

Some of vsftpd’s settings don’t fit the filesystem layout by

default.

This option should be the name of a directory which is empty. Also, the

directory should not be writable by the ftp user. This directory is used

This option should be the name of a directory which is empty. Also, the

directory should not be writable by the ftp user. This directory is used

as a secure chroot() jail at times vsftpd does not require filesystem

access.

secure_chroot_dir=/var/run/vsftpd/empty

This string is the name of the PAM service vsftpd will use.

pam_service_name=ftp

This option specifies the location of the RSA certificate to use for SSL

encrypted connections.

#rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
#rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
rsa_cert_file=/etc/ssl/private/vsftpd.pem
rsa_private_key_file=/etc/ssl/private/vsftpd.pem
ssl_enable=YES
allow_anon_ssl=NO
force_local_data_ssl=YES
force_local_logins_ssl=YES
ssl_tlsv1=YES
ssl_sslv2=NO
ssl_sslv3=NO
require_ssl_reuse=NO
ssl_ciphers=HIGH

Uncomment this to indicate that vsftpd use a utf8 filesystem.

#utf8_filesystem=YES
