컴퓨터실 내부에서 윈도우 클라이언트로 로그인 하는 경우는 그렇다 치자.
프로필에서 삼바 서버를 직접 정확하게 적어주면 바로 저장서버로
연결이 되니까 말이다. 하지만 FTP로 서버를 NFS로 거쳐 저장서버로 연결이 되면
직접 연결될 때보다 불필요하게 오가는 신호가 생기는 것이다 ㅡㅡa
[[서버1: FTP]] ---NFS --- [[저장서버]]
해결중인문제... 끄응...
Raid장비를 안 쓰는만큼
Raid와 컴퓨터를 오가는 정보가 네트워크를 오가는거지 ㄱ-...;
일단은 그 현상을 완화해보고자 했다.
스토리지서버니까 AD유저의 정보를 getent passwd로 읽을 수는 있게 하기 위해.
system-config-authentication
을 실행시켜서 LDAP과 관련된 것을 잘 설정하고
nsswitch.conf도 잘 수정해준다.
/etc/pam.d/system-auth
파일을 수정해서 ldap과 관련된 라인은 코멘트 처리한다.
이제 이 파일을 vsftpd로 복사한다.
이 파일에서만 ldap관련 라인을 코멘트 해제처리.
그러면 ftp에는 유저가 접속하여 파일을 받아갈 수 있는 것이다.
필자의 vsftpd파일 (stack을 써서 효율적으로 만들 수 있겠지만.)
root의 로그인을 불허하는 것도 넣어주었다.

vsftpd.conf설정
# 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.
# 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.
#
# 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 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
#
# 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

#
# 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 turning on ascii_download_enable enables malicious remote parties
# to consume your I/O resources, by issuing the command "SIZE /big/file" in
# ASCII mode.
# These ASCII options are split into upload and download because you may wish
# to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),
# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be
# on the client anyway..

# You may fully customise the login banner string:

# (default follows)
#banned_email_file=/etc/vsftpd.banned_emails

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

# users to NOT chroot().
chroot_list_enable=YES
chroot_local_user=YES
# (default follows)
chroot_list_file=/etc/vsftpd/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

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