[Original article http://www.5ilinux.com/vsftp01.html]
This is the first article written by my rookie to learn Linux. It is the application of the basic FTP erection application. If I have any questions, please advise, I will continue to move in the FTP in various details. Configure to discuss with everyone. What I use is the system architecture of Redhat Linux as vsftpd-1.2.0-4, which illustrates if it is not very familiar with the configuration file, it is best to make a backup, so as not to operate:
Connection of anonymous servers (separate servers)
Add a few items in the /etc/vsftpd/vsftpd.conf profile:
Anonymous_enable = yes (Allow anonymous login) DirMessage_enable = YES (When switching the directory, display the contents of the directory. Message)
Local_umask = 022 (Local file permissions on FTP, default 077)
Connect_form_port_20 = yes (Enable data connection for FTP data port) *
Xferlog_enable = YES (Activate the log of uploading and the log)
Xferlog_std_format = yes (using standard log format)
ftpd_banner = xxxxx (welcome information)
PAM_SERVICE_NAME = VSFTPD (Verification Mode) *
Listen = YES (independent VSFTPD server) *
Function: You can only connect to the FTP server, you can't upload and submit: where all and log welcome information related to the option, the asterisk, no matter what account, you have to add, it is the basic option belonging to FTP.
Open anonymous FTP server uploading authority
Add the following information to the configuration file:
Anon_upload_enable = yes (open upload authority)
Anon_mkdir_write_enable = yes (can create a directory to upload files in this directory)
Write_enable = YES (Open Local User Write Permissions)
Anon_other_write_enable = yes (anonymous account can have permission to delete)
Open the permissions issued by anonymous server
Add the following information in the configuration file:
Anon_World_Readable_only = no
Note: Pay attention to the properties of the folder, an anonymous account is other (other) user to turn on its read and write permission (R) read ----- Upload (W) Write ---- Upload (X) Execution ---- If you don't open the directory of FTP, you can't get it.
Ordinary user FTP server connection (independent server)
Add the following information in the configuration file:
Local_enble = YES (local account can log in)
Write_enable = no (no right to delete and modify file after login)
Function: You can log in to the VSFTPD server with a local account, there is a permission to download upload Note: An anonymous server can be logged in after anonymous login, but can not be uploaded
User login restrictions into other directories, can only enter its home directory
Set all local users to perform chroot
Chroot_local_user = yes (all accounts can only be in their own directory)
Set the specified user to execute Chroot
Chroot_list_enable = yes (the list in the file can be called)
CHROOT_LIST_FILE = / Any specified path /VSFTPD.CHROOT_LIST
Note: vsftpd.chroot_list is not created, you need to add yourself, you want to control your account directly to add an account in the file.
Limit local users access FTP
UserList_enable = YES (with UserListLai to limit user access)
UserList_Deny = NO (people in the list are not allowed)
UserList_file = / Specifies the path to the file / (the path placed by the file)
Note: Open UserList_enable = YES Anonymous account cannot be logged in
Security Option Idle_Session_Timeout = 600 (second) (10 minutes after the user session is idle)
DATA_CONNECTION_TIMEOUT = 120 (seconds) (2 minutes to connect data)
Accept_timeout = 60 (seconds) (after passing the client 1 minute later)
Connect_timeout = 60 (seconds) (reconnected after 1 minute)
Local_max_rate = 50000 (Bite) (Local User Transfer Rate 50K)
Anon_max_rate = 30000 (Bite) (Anonymous User Transfer Rate 30K)
PASV_MIN_PORT = 50000 (transform the client's data connection port
PASV_MAX_PORT = 60000 50000-60000)
MAX_CLIENTS = 200 (the maximum number of ftps)
Max_Per_ip = 4 (maximum number of connections per IP)
Listen_Port = 5555 (data connection from the 5555 port)

[Original article http://www.5ilinux.com/vsftp02.html]
I am not a master! ! ! ^ _ ^ I just a rookie, do my best to write the master articles I feel this rookie, so if there is any mistake, please refer to it! ! !
Environment: System architecture of Linux AS 3.0 vSFTPD-1.2.0-4 is under the standalone server! I hate xinetd ^ _ ^
Configure the FTP accessible for local groups
First create the main directory of user group TEST and FTP
GroupAdd Test
MKDIR / TMP / TEST
Then create a user
UserAdd -g test -d / tmp / test -m usr1
Note: g: The group of users d: indicates that the location of the creating the user's own directory is given
M: Do not build a default home directory, that is, there is no direct directory under / home.
UserAdd -g test -d / tmp / test -m usr2
Then change the owner and permissions of the folder
Chown usr1.test / tmp / test - "This means that the / TMP / TEST is the most USR1
CHMOD 750 / TMP / TEST ---- 7 indicates that WRX 5 indicates that the RX 0 does not have any permissions.
The purpose of this experiment is USR1 with permissions for uploading, deleting and downloading.
And USR2 only downloaded permissions without uploading and deleting permissions
Of course, don't forget our main configuration file vsftpd.conf
To determine local_enable = yes, write_enable = yes, chroot_local_usr = YES These three options are there!
Non-port standard mode for configuring independent FTP servers for data connection
This is very easy: in vsftpd. Add
Listen_Port = 33333
Yes!
Configure a separate virtual FTP, use virtual FTP users, and make different permissions in the four accounts.
(Two permissions with read directory, a permission with browsing, uploading, downloading, a permission with browsing, download, deletion, and change the writing name) A: Configuring the NIC
The first network card address is 10.2.3.4 mask is 255.255.0.0.0
IFConfig Eth0: 1 211.131.4.253 Netmask 255.255.255.0 Up
B: Write / etc / sysconfig (in order to restart, IP address will not be lost)
CD / ETC / Sysconfig / Network-scripts
CP ifcfg-eth0 IFCFG-ETH0: 1
VI ifcfg-eth0: 1 in it is modified as follows
Device = eth0: 1
Broadcast = 211.131.4.255
Hwaddr = MAC address of the NIC
Ipaddr = 211.131.4.253
Netmask = 255.255.255.0
NetWork = 211.131.4.0
Onboot = YES
TYPE = Ethernet
WQ exits
C: Enter the folder where vsftpd.conf is located
CP vsftpd.conf vsftpd2.conf
Modify vsftpd.conf Add the following information
Listen_address = 10.2.3.4
Modify vsftpd2.conf Add the following information
Listen_address = 211.131.4.253
FTPD_BANNER = this is a Virtual FTP TEST
This virtual FTP server is established.
D: Establish logins.txt
Vi /TMP/logins.txt
Add information:
Longlei ------------ User Name
Longlei ------------ password
ZhangWeibo
ZhangWeibo
Jinhui
Jinhui
LXP
LXP
In the format, follow me, a user name, a password.
E: Establish a visitor's password library file, then modify its permissions
DB_LOAD -T -T HASH -F /TMP/LOGINS.TXT / Etc/vsftpd_login.db
F: Enter ftp.vu in /etc/pam.d/
Add the following information to this file
Auth Required /Lib/security/pam_userdb.so db = / etc / vsftpd_login
Account Required /Lib/security/pam_userdb.so db = / etc / vsftpd_login
G: In / var / ftp / creation directory and change its properties and its homeowner
UserAdd -d / var / ftp / test qiang
CHMOD 700 / VAR / FTP / TEST
Add Test_File test files in the catalog
H: Enter vsftpd2.conf to modify the information
Listen_yes
Anonymous_enable = no
Local_enable = YES
Write_enable = no
Anon_upload_enable = no
Anon_mkdir_write_enable = no
Anon_other_write_enable = no
Chroot_local_user = yes
Guest_enable = yes ---------- Enperse virtual users
Guest_username = qiang ------ map virtual users to local users
Listen_Port = 5555
MAX_CLIENT = 10
MAX_PER_IP = 1
Ftpd_banner = this is a Virtual Server and Users
PAM_SERVICE_NAME = ftp.vu Note: The lower the permissions given in the primary configuration file, the larger the space for the permissions of the support when the user is managed later, because the highest restriction service of the main configuration file first reads the master profile, Then read the user's configuration file
Repeated service. It's just built in this virtual user.
I: Create a Virtaul file directory in the directory where vsftpd.comf is located and create a configuration file named by your username in the file directory.
Longlei ZhangWeiBo Jinhui LXP
Add:
Anon_World_Readable_only = no
Add in LXP
Anon_World_Readable_only = no
In this way, the two users have the right to browse the directory.
Add in jinhui
Anon_World_Readable_only = no
Write_enable = YES
Anon_upload_enable = yes
This user has permission for uploading, downloading and browsing.
Add from ZhangWeibo
Anon_World_Readable_only = no
Write_enable = YES
Anon_upload_enable = yes
Anon_other_write_enable = yes
This user has an upload, download, delete file directory, modify the file name and browse.

Now there is no information on maintaining the VSFTP server. Welcome everyone to edit 2
Some supplements used by VSFTP
Add 1: How do I choose to limit the user to my home directory?
We have to build a file yourself, in the / etc directory
#touch /etc/vsftpd.chroot_list
Benan and NANBEI are limited to their home directory, while other FTP users do not do this.
In the vsftpd.chroot_list this file, add Beinan and Nanbei to the line, pay attention, each user occupies a row.
Beinan
Nanbei
Then change the /etc/vsftpd/vsftpd.conf file, find the following two lines
# chroot_list_enable = yes
# chroot_list_file = / etc / vsftpd.chroot_list
Take the front ##, that is, this
Chroot_list_enable = yes
Chroot_list_file = / etc / vsftpd.chroot_list
If there is no such two lines, you can add it to you.
After setting up, re-vsftpd servers.
Supplementary Supplement: How to limit all FTP users in the system in the catalog? ? After Juliaugong's prompt, I found the foreign language description of VSFTPD, prove that this option is a knife to solve all users can limit the directory at home.
We can add the following line by changing the vsftpd.conf file.
chroot_local_user = yes
Don't forget to restart the VSFTPD server
[root @ linuxsir001 root] # /etc/init.d/vsftpd restart
Turn off vsftpd: [OK]
Start VSFTPD for VSFTPD: [OK]
[root @ linuxsir001 root] #
Supplement 2: Open the log function of the VSFTP server
Try the # number in front of the xferlog_file below, that is, open the VSFTP's log function so that we can view vsftpd.log in / var / log directory. This is VSFTP log function, which is extremely important for us.
# xferlog_file = / var / log / vsftpd.log
Add 3: How to make the bound IP to VSFTP?
That is, how to let users access FTP through an IP. In fact, this feature is very interesting. If binding is the IP of the intranet, there is no way to access it outside. If binding is an external service IP, the intranet can only access FTP through an external service IP.
Plus a line in /etc/vsftpd/vsftpd.conf, take my local area network as an example, please see the operating environment in the first post, so that the external network can not access my FTP, the intranet may also pass 192.168.0.2 Access FTP
Listen_address = 192.168.0.2
After adding, restart the VSFTP server
[root @ Linuxsir001 root] # /etc/init.d/vsftpd Restart Close VSFTPD: [OK]
Start VSFTPD for VSFTPD: [OK]
[root @ linuxsir001 root] #
Supplement 4: How to make the VSFTP server limit the number of links, and the maximum number of links to each IP? ?
A: You should change the formulation of the VSFTP server vsftpd.conf, add the following two lines:
MAX_CLIENTS = number
MAX_PER_IP = number
Example: I want my VSFTP to maximize the number of links, each IP, up to 5 links, so I should add the following two lines in vsftpd.conf:
MAX_CLIENTS = 100
MAX_PER_IP = 5
Change the formulation of the file, don't forget to start the VSFTP server.
Supplement 5: How to limit the speed of download?
Anon_max_rate = Note: This is anonymous download speed local_max_rate = number Note: This is the download speed of ordinary users on the VSFTP server
Note: The unit of this number is byte, so we have to calculate it. For example, I want to let the users on the anonymous user and VSFTP in 80kb, so this number should be 1024x80 = 81920 so we have to add the following two lines in vsftpd.conf.
Anon_max_rate = 81920
LOCAL_MAX_RATE = 81920
Don't forget to restart VSFTPD services
Add 6: My hard disk is limited, what should I do?
My hard disk space is limited, how do I change my account ftp default path / VAR / FTP? Or, all of my Linux is placed in / root partition, because the space is tight, can I put the default path of the FTP user to another partition?
Yes, you should do it as follows!
First of all, remove the FTP user
# urserdel -r ftp
There will be error messages, but it is normal.
Then we add this user again. For example, I want to set the account FTP home directory in / mnt / ling / ftp, we can do the following
[root @ Linuxsir001 root] # MKDIR / MNT / LING
[root @ Linuxsir001 root] # adduser -d / mnt / ling / ftp -g ftp -s / sbin / nologin ftp
Just don't do this, because this still can't let anonymous user find its home directory, so we must change the permissions of / mnt / ling / ftp.
[root @ linuxsir001 root] # chmod 755 / mnt / ling / ftp /
[root @ linuxsir001 root] # chown -r root.root / mnt / ling / ftp /
Supplementary 7: How to customize welcome information
How to appear after we log in to some FTPs: Welcome to LinuxSir FTP, here, you will get the most sincere help, if there is any questions and suggestions, please let me know, thank you.
It is not difficult to implement this, we can view the vsftpd.cof file, whether there is this line.
DirMessage_enable = YES
If you don't add, if DirMessage_enable = YES has ##, you will remove the ##.
Then we develop a .message file, write something you want to write, such as. Message content is as follows: Welcome to LinuxSir ftp!
Here you will get the most sincere help;
If there is any questions and suggestions, please let me know, thank you.
We can use the editor to write this. Message, I don't want to say this process.
Then we copy the .message file to the home directory of each user. For example, a user of my FTP is Beinan, the home directory where the user is located is / Home / Beinan
We have to put it in the / home / beinan in this directory. If the system user ftp, his directory is / var / ftp this directory, this is the default, and when an anonymous user logins is the / var / ftp directory. We want an anonymous user to see welcome information. It is necessary to put it in / var / ftp directory. Other users, nothing more than similar operations.
Supplement 8: How to implement a virtual path?
For example: / home / a mapping to ftp: // localhost / A / home / b / c is ftp: // localhost / c
In fact, this cannot be said to be vsftpd content. In fact, we have already touched it, probably we don't pay attention, we can be implemented by the following methods.
#mount --bind [Original Contents] [New Directory]
For example, my FTP's default directory is / var / ftp, I want to put the / mnt / ling / winsoft folder, mapped to / var / ftp directory, I will do this
We must first build a directory in / var / ftp directory
#mkdir / var / ftp / winsoft
Then execute the mount command
#mount - Bind / MNT / LING / WINSOFT / VAR / FTP / WINSOFT
This is OK.
Supplement Nine: How to get anonymous access, upload, and support download and execute?
In the default, VSFTP does not support access to anonymous users, so we have to open the appropriate options yourself. Now I am in response to this problem, we have to open the following options.
Anonymous_enable = yes Note: Allow anonymous access
Anon_upload_enable = yes Note: Allow upload
Anon_mkdir_write_enable = yes Note: Allows the establishment of a corresponding directory
Anon_umask = 022 Transmitted to FTP file or directory change permission
Of course, open these options or not, we also want to let anonymous write files have written rights, with the FTP I have made, the FTP I have done is / var / ftp In VSFTPD, / var / ftp is not allowed to make an anonymous users write permissions. This is for security considerations, so we must build a directory in / var / ftp directory, let this directory written right .
For example: I built a UPLOAD directory in / var / ftp directory, and then set it to 777, so anonymous users can write.
#mkdir / VAR / FTP / UPLOAD
#CHMOD 777 / VAR / FTP / UPLOAD
Change a series of files, don't forget to restart the vsftpd server
I used Standalone mode, of course, using the following method
[root @ Linuxsir001 root] # service vsftpd restart
Turn off vsftpd: [OK]
Start VSFTPD for VSFTPD: [OK]
[root @ linuxsir001 root] #
If you use the xinetd mode to start vsftpd, we have to restart the xinetd server [root @ Linuxsir001 root] # Service Xinetd Restart
Stop xinetd: [OK]
Start xinetd: [OK]
[root @ linuxsir001 root] #]
Add 10: Adding a virtual user through the PAM authentication method
With PAM certification, add users with DB_LOAD, is a real virtual user. Now we briefly introduce, through future learning, we will further add:
1. Create a file FTP in the /etc/pam.d/ directory
[root @ Linuxsir001 root] # Touch /etc/pam.d/FTP
2. Inside /etc/pam.d/ftp plus the following two lines
Auth Required /Lib/security/pam_userdb.so db = / etc / vsftpd_login
Account Required /Lib/security/pam_userdb.so db = / etc / vsftpd_login
3. Create a user-friendly file logins.txt
[root @ linuxsir001 root] # Touch logins.txt
In the logins.txt file, enter the following content. You can be your own. For example, I will below. In fact, LinuxSir007 is a virtual user name of FTP. password.
Linuxsir007
123456
Linuxsir008
234567
Linuxsir009
567890
Linuxsir010
678901
Linuxsir011
789012
4. Create a real user name LinuxSir006, this LinuxSir006 user, the home directory is scheduled by you. I have said not much here. I am added by the system default.
[root @ Linuxsir001 root] # UserAdd Linuxsir006
5. Copy / etc / hosts to / home / linuxsir006 and change its host
[root @ Linuxsir001 root] #CP / etc / hosts / home / linuxsir006 / hosts
[root @ Linuxsir001 root] #Chown Linuxsir006.LinuxSir006 / HOME / LinuxSir006 / Hosts
6. Create a library file of a virtual user via db_load. We built a logins.txt file in front, I am in the / root user directory. So we have to switch the directory to the / root directory to create a library file for the virtual user.
[root @ Linuxsir001 root] # db_load -t -t hash -f logins.txt /etc/vsftpd_login.db
7. Change the vsftpd.conf file, join the following lines
PAM_SERVICE_NAME = FTP
Guest_enable = yes
guest_username = linuxsir006
Anon_World_Readable_only = no
8. Restart the VSFTPD server; change a series of files, don't forget to restart the vsftpd server
I used Standalone mode, of course, using the following method
[root @ Linuxsir001 root] # service vsftpd restart close vsftpd: [OK]
Start VSFTPD for VSFTPD: [OK]
[root @ linuxsir001 root] #
If you use the xinetd mode to start vsftpd, we have to restart the Xinetd server
[root @ linuxsir001 root] # service xinetd Restart
Stop xinetd: [OK]
Start xinetd: [OK]
[root @ linuxsir001 root] #
9. If you want the user to log in to FTP, log in to successful information, please copy you .Message to your user's home directory, please refer to the previous supplements.
10. test:
[root @ linuxsir001 root] # ftp 192.168.0.1

Reix 11: How to start the system with Standalone boot to start with xinetd?
How to install the system defaults in Redhat 9.0, the system default vsftpd is started with the Standalone launch method, changed to the xinetd startup mode? If it is installed with the source package, the XINETD mode is installed after installation. If it is installed with an RPM package, in Redhat 9.0, you should use the following method to solve it.
1. Create a file vsftpd in the /etc/xinetd.d/ directory
[root @ linuxsir001 root] # Touch /etc/xinetd.d/vsftpd
/etc/xinetd.d/vsftpd content is as follows:
Service ftp
{
Socket_type = stream
Wait = NO
User = root
Server = / usr / sbin / vsftpd
# Server_args = # log_on_success = DURATION UserId
# log_on_failure = UserID
Nice = 10
Disable = no
}
2. Copy vsftpd.conf to / etc / directory, because Xinetd is in / etc directory, so we must copy this file to the / etc directory, otherwise there will be a LOCAL user in the system cannot log in, that is To put it, you don't have a copy of this document that FTP non-anonymous users cannot access it, only with anonymous user access.
[root @ Linuxsir001 root] # CP /etc/vsftpd/vsftpd.conf /etc/vsftpd.conf
3. Change the formulation file /etc/vsftpd.conf, note the following items: That is
Listen = yes
Change to
# listen = yes
Or delete this line.
4. Remove the /etc/init.d/vsftpd file. In fact, the best backup is elsewhere, because we sometimes go to the experiment, may also go to the Standalone mode startup. I move directly to other directories, such as the Backup directory below / root.
[root @ Linuxsir001 root] #MKDIR / ROOT / BACKUP
[root @ linuxsir001 root] # mv /etc/init.d/vsftpd / root / backup
5. Run NTSYSV, cancel the service of VSFTPD
[root @ Linuxsir001 root] #ntsysv
vsftpd
6. Restart the xinetd service
[root @ linuxsir001 root] # service xinetd Restart
