Test FTP service, installed in the ali cloud VSFTPD, FTP can be the connection is successful, but the ls, dir is not display content, get file also failed, turn to the great god,
1, the conf file
# Example config file/etc/VSFTPD/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.
# both Please see VSFTPD. Conf. 5 for all compiled in defaults.
#
# READ THIS: THIS example file is NOT an exhaustive list of VSFTPD options.
# do read the VSFTPD. Conf. 5 manual page to get a full idea of VSFTPD 's
# "capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
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 2 (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.
# the When SELinux is enforcing the check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access
# 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
#
# 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 company user. Note! Using "root" for uploaded files is not
# it!
# chown_uploads=YES
# chown_username=whoever
#
# You may override the where the log file goes if You like. The default is to
# below.
# xferlog_file=/var/log/xferlog
#
# 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 It that you define on your system a unique user which the
# 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
# it for security (the code is non - trivial). Not enabling it,
# clear that may confuse older FTP clients.
# async_abor_enable=YES
#
# By default, the server will pretend to ASCII mode but in fact ignore
# the request. Turn on the below options and the server later do ASCII
# mangling on files when in ASCII mode. The VSFTPD. Conf (5) man page explains
# the behaviour when these options are disabled.
# Beware that on some FTP servers, ASCII support allows a "of the service
# attack (DoS) via the command "SIZE/big/file" in ASCII mode, VSFTPD
# predicted this attack and has always had safe, reporting the size of the
# raw file.
# ASCII mangling is a latest 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
# (the default follows)
# banned_email_file=/etc/VSFTPD/banned_emails
#
# 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
# (the default follows)
# chroot_list_file=/etc/VSFTPD/chroot_list
#
# You may activate the "of" the -r option to the builtin ls. This is disabled by
# default to get remote users being able to cause excessive I/O on large
# sites. Or, some other FTP clients to as "NCFTP" and "mirror" assume
# the presence of the "-r" option, so there is a strong case for enabling it.
# ls_recurse_enable=YES
