Learning to configure VSFTP for FTP file transfer

I. FTP instructions

The common FTP in Linux system is vsftp, that is, very Security File Transfer Protocol. There is also a proftp (profession FTP). Here is also a simple description of the configuration under Vsftp.

VSFTP provides 3 types of remote login options:

(1) Anonymous login method

Just don't need username, password. You can log in to the server computer.

(2) Local user mode

You need an account name and password to log in. And, this account name and password, are in your Linux system, already have users.

(3) Virtual user mode

You also need a user name and password to log in. But the difference with the above is that this username and password is not in your Linux system (no user account)

Two.UBUNTU FTP setup:

2.1 Installation

VSFTP installation package, can be found in the installation. The installation process with Yum is also simple.
Install command: Yum install vsftpd--------"I've tried this, and I'm not in Ubuntu,

Recommended for this: Run the new FTP service command at Terminal:Sudo apt-get install vsftpd

3. To change the configuration, configure the following:

Listen=yes

Anonymous_enable=no

Local_enable=yes

Write_enable=yes

Anon_upload_enable=yes

Anon_mkdir_write_enable=yes

Dirmessage_enable=yes

Use_localtime=yes

Xferlog_enable=yes

Connect_from_port_20=yes

Chown_uploads=yes

Chown_username=sa

Xferlog_file=/var/log/vsftpd.log

Pam_service_name=vsftpd

Rsa_cert_file=/etc/ssl/private/vsftpd.pem

4. Restart the FTP service sudo/etc/init.d/vstpd restart

---------"Restart here I tried not to, use a few, you can

2.2.1 Start and close

[[Email protected] ~]# service VSFTPD start

Starting vsftpd for VSFTPD: [OK]

[[Email protected] ~]# service VSFTPD stop

Shutting down VSFTPD: [OK]

[Email protected] ~]# service vsftpd restart

------The following can be done without looking, you want to try it--------

Shutting down VSFTPD: [FAILED]

Starting vsftpd for VSFTPD: [OK]

[[email protected] ~]#/etc/init.d/vsftpd start

Starting vsftpd for VSFTPD: [FAILED]

[[email protected] ~]#/etc/init.d/vsftpd stop

Shutting down VSFTPD: [OK]

[Email protected] ~]#/etc/init.d/vsftpd restart

Shutting down VSFTPD: [FAILED]

Starting vsftpd for VSFTPD: [OK]

[Email protected] ~]#/ETC/INIT.D/VSFTPD status

VSFTPD (PID 3931) is running ...

[Email protected] ~]#

2.2.2. Other commands

--View vsftpd boot status

[[email protected] ~]# chkconfig--list vsftpd (this piece can you need to download Chkconfig:sudo apt-get install chkconfig)

VSFTPD 0:off 1:off 2:off 3:off 4:off 5:off 6:off

--------did not try, I do not have a firewall, do not have to try----------------------

[Email protected] ~]# chkconfig vsftpd on

[Email protected] ~]# chkconfig--list vsftpd

VSFTPD 0:off 1:off 2:on 3:on 4:on 5:on 6:off

As you can see here, from 2 to 5 is set to on by default. 2 to 5 is a multi-user level. This corresponds to the different operating levels of Linux.

We can also add the level option to specify:

[[email protected] ~]# chkconfig--level 0 vsftpd on

[Email protected] ~]# chkconfig--list vsftpd

VSFTPD 0:on 1:off 2:on 3:on 4:on 5:on 6:off

We see that 0 is set to ON.

We can use the man chkconfig to see the help:

--level levels

Specifies the run levels an operation should pertain to. It is given as a string of numbers from 0 to 7. For example,--level specifies Runlevels 3 and 5.

Traditional init defines 7 runlevel (run level), each representing some specific services that the system should complement:

(1) Level 0 is a complete shutdown of the system

(2) Class 1 or S-class stands for single-user mode

(3) Level 2-5 is a multi-user level

(4) 6 level is the level of reboot
