Build FTP and error on Linux

First build FTP.

Note: This example is installed in the REDHAT6 64 system; Most Linux configurations are the same

One. Installation

1. Confirm that the Yum source "my yum source is directly used Redhat disk is relatively simple, while confirming that the disc has been used Mount/dev/cdrom/media This command is attached to the/media"

rm-rf/etc/yum.repos.d/*

Vi/etc/yum.repos.d/yum.repo

[Yum]

Name=yum

Baseurl=file:///media

Enabled=1

Gpgcheck=0

Wq Save exit

2. Confirm the network configuration

Vi/etc/sysconfig/network-scripts/ifcfg-eth0

Device=eth0

Onboot=yes

Bootproto=static

ipaddr=192.168.10.126

netmask=255.255.255.0

gateway=192.168.10.1

dns1=202.106.0.20

Wq Save

Detection: You can ping the gateway 192.168.10.1 detect if the

3. Install the required packages for FTP

Yum-y Install VSFTPD

Two. Configuration and explanation

FTP configuration file in the/etc/vsftpd/directory

Ftpusers---------used to specify which users cannot access the FTP server

②.user_list ---------used to add FTP users so that they can log on or not log on to the FTP server (in the same color font as detailed)

③.VSFTPD.CONFG ---------The main configuration file for FTP

The ②.FTP server starts when the vsftpd.conf file is detected first, if the following statement is detected in the file

Userlist_deny=yes

The user that exists in the User_list file is not allowed to log on to the FTP server, and yes is the default option for that sentenceUserlist_deny=noonly allow users in the file to log on to the FTP server, and other users cannot log on to the FTP server. The file is in the same format as ftpusers. If you want to add a user, each user name has a single row③.

User Login Control:

Anonymous_enable=yes, allowing anonymous users to log on.

No_anon_password=yes, anonymous users do not need to enter a password when they log on.

Local_enable=yes, allowing local users to log on.

Deny_email_enable=yes, you can create a file to save the blacklist of some anonymous emails to prevent these people from using Dos attacks.

Banned_email_file=/etc/vsftpd/banned_emails, the directory where the email blacklist is saved (default)

User Rights control:

Write_enable=yes, turn on global uploads

local_umask=022, the local file upload umask is set to 022, system default.

Anon_upload_enable=yes, allow anonymous users to upload, of course, in the case of Write_enable=yes. You must also create a directory that allows FTP users to read and write.

Anon_mkdir_write_enable=yes, allow anonymous to create a directory with flowers

Chown_uploads=yes, anonymous users upload the file is the main conversion to other users, the general recommendation is root.

Chown_username=whoever, change the whoever here to the owner to be converted, suggest root

Chroot_list_enable=yes, use a list to limit which users can only be active in their own directory.

Chroot_list_enable=/etc/vsftpd/chroot_list, specifying the user list file

Nopriv_user=ftpsecure, specify a secure account to allow FTP to be fully isolated and without privileged accounts

Other recommendations are not configured.

User connection and timeout settings:

idle_session_timeout=600, default time-out

data_connection_timeout=120, setting the default data connection time-out

Server logs and welcome information

Dirmessage_enable=yes, allowing information to be displayed for the configuration directory

Ftpd_banner=welcome to blah FTP service. Welcome information for FTP

Xferlog_enable=yes turning on the logging feature

Xferlog_file=/var/log/xferlog the location of the log record file

Three. Configuration Complete reboot

Service VSFTPD Restart

Four. Verify

Can be verified with Windows Server ftp://192.168.10.126

PS: Access vsftpd in cmd

Help available command query

PWD current Directory

CD entry

Bin binary transfer (facilitates fast download

Mrdir Deleting a directory

Quit quitting

Five. Error
