一、基础环境
1、版本
cat /etc/debian_version
7.8
2、内核
uname -r
3.2.0-4-amd64
3、proftpd版本
ProFTPD Version 1.3.4a
4、ip(eth0)
10.1.10.117服务端
10.1.10.160客户端
5、proftpd官网
http://www.proftpd.org/
6、需求
只允许fileftp用户连接并登录ftp并锁定在自定义的家目录中 其他系统(匿名)用户不能登录ftp，监听在本机的eth0地址
二、安装配置proftpd服务端10.1.10.117
1、apt方式安装
apt-get -y install proftpd-basic
2、创建ftp目录
mkdir /opt/ftpdata -p
3、创建ftp账户并修改密码
1)useradd -s /bin/false fileftp -d /opt/ftpdata
2)echo fileftp:redhat|chpasswd
4、修改配置
1)备份下配置
cp /etc/proftpd/proftpd.conf /etc/proftpd/proftpd.conf.bak
2)cat /etc/proftpd/proftpd.conf
Include /etc/proftpd/modules.conf
RootLogin off
IdentLookups off
UseReverseDNS off
ServerIdent off
AllowStoreRestart on
AllowRetrieveRestart on
ServerName "Debian"
ServerType standalone
MultilineRFC2228 on
DefaultServer off
ListOptions "-l"
DenyFilter \*.*/
DefaultRoot /opt/ftpdata
RequireValidShell off
DefaultAddress 10.1.10.117
SocketBindTight on
Port 21
MaxInstances 30
User proftpd
Group nogroup
Umask 022 022
AllowOverwrite on
TransferLog /var/log/proftpd/xferlog
SystemLog /var/log/proftpd/proftpd.log
5、配置说明
Include /etc/proftpd/modules.conf
RootLogin off #禁止root登录
IdentLookups off #禁止DNS反查
UseReverseDNS off #禁止DNS反查
ServerIdent off #隐藏版本号
AllowStoreRestart on #支持上传续传
AllowRetrieveRestart on #支持下载续传
ServerName "Debian" #服务器名称
ServerType standalone #使用standalone方式启动服务
MultilineRFC2228 on #FTP安全扩展
DefaultServer off #关闭默认主机
ListOptions "-l" #
DenyFilter \*.*/ #
DefaultRoot /opt/ftpdata #锁定在/opt/ftpdata目录中，可以进下一级目录
RequireValidShell off #不指定ftp用户的shell
DefaultAddress 10.1.10.117 #监听地址
SocketBindTight on
Port 21 #监听端口
MaxInstances 30 #最大线程数
User proftpd #以proftpd用户运行
Group nogroup #以nogroup组运行
Umask 022 022 #用户文件属性
AllowOverwrite on #能重写、覆盖
TransferLog /var/log/proftpd/xferlog #日志
SystemLog /var/log/proftpd/proftpd.log #日志
6、修改/etc/shell配置文件增加/bin/false
echo "/bin/false" >> /etc/shells
7、/etc/proftpd/modules.conf还需要注释掉1个modules
sed -i "s/LoadModule mod_tls_memcache.c/#LoadModule mod_tls_memcache.c/g" /etc/proftpd/modules.conf
8、配置/etc/ftpusers使只能fileftp用户登录ftp
1)cp /etc/ftpusers /etc/ftpusers.bak
2)cat /etc/passwd|grep -v "fileftp"|awk -F: ‘{print $1}‘ > /etc/ftpusers
9、重启proftpd服务
/etc/init.d/proftpd restart
[ ok ] Stopping ftp server: proftpd.
[ ok ] Starting ftp server: proftpd.
10、查看端口
netstat -tupnl |grep 21
tcp 0 0 10.1.10.117:21 0.0.0.0:* LISTEN 7441/proftpd: (acce
11、查看进程
ps -ef |grep proftpd
proftpd 7441 1 0 15:03 ? 00:00:00 proftpd: (accepting connections)
三、客户端测试10.1.10.160
1、先安装lftp
apt-get -y install lftp
2、创建fileftp用户ftp传输目录
mkdir /opt/ftpdata/fileftp -p && cd /opt/ftpdata/ && chown fileftp.fileftp fileftp
3、linux下使用lftp命令测试
lftp fileftp:‘redhat‘@10.1.10.117
lftp jimmy:‘redhat‘@10.1.10.117
lftp root:‘redhat‘@10.1.10.117
lftp 10.1.10.117
4、查看日志可以看到只有fileftp用户可以登录

5、工具测试(FlashFXP)
四、服务端配置ssl 1、安装包 apt-get -y install openssl 2、创建一个证书(时间365天)并填写相关一些信息 openssl req -x509 -nodes -days 365 -newkey rsa:2048 -out /etc/ssl/certs/proftpd.pem -keyout /etc/ssl/certs/proftpd.pem Generating a 2048 bit RSA private key ............................................................................................................................+++ ...................+++ writing new private key to ‘/etc/ssl/certs/proftpd.pem‘ ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter ‘.‘, the field will be left blank. ----- Country Name (2 letter code) [AU]:CN State or Province Name (full name) [Some-State]:shanghai Locality Name (eg, city) []:shangahi Organization Name (eg, company) [Internet Widgits Pty Ltd]:aaa Organizational Unit Name (eg, section) []:aaa Common Name (e.g. server FQDN or YOUR name) []:aaa Email Address []: 3、修改权限 chmod 0400 /etc/ssl/certs/proftpd.pem 4、修改/etc/proftpd/proftpd.conf支持tls 添加在最后 TLSEngine on TLSRequired on TLSProtocol TLSv1 SSLv23 TLSLog /var/log/proftpd/tls.log TLSRSACertificateFile /etc/ssl/certs/proftpd.pem TLSRSACertificateKeyFile /etc/ssl/certs/proftpd.pem 5、重启服务 /etc/init.d/proftpd restart [ ok ] Stopping ftp server: proftpd. [ ok ] Starting ftp server: proftpd. 6、工具测试(FlashFXP)
7、查看日志 Aug 05 16:11:30 mod_tls/2.4.3[8577]: using default OpenSSL verification locations (see $SSL_CERT_DIR environment variable) Aug 05 16:11:30 mod_tls/2.4.3[8577]: TLS/TLS-C requested, starting TLS handshake Aug 05 16:11:30 mod_tls/2.4.3[8577]: TLSv1/SSLv3 connection accepted, using cipher DHE-RSA-AES128-SHA (128 bits) Aug 05 08:11:31 mod_tls/2.4.3[8577]: Protection set to Private Aug 05 08:11:31 mod_tls/2.4.3[8577]: starting TLS negotiation on data connection Aug 05 08:11:31 mod_tls/2.4.3[8577]: TLSv1/SSLv3 renegotiation accepted, using cipher DHE-RSA-AES128-SHA (128 bits) Aug 05 08:11:31 mod_tls/2.4.3[8577]: client reused SSL session for data connection Aug 05 08:11:31 mod_tls/2.4.3[8577]: TLSv1/SSLv3 data connection accepted, using cipher DHE-RSA-AES128-SHA (128 bits) Aug 05 16:33:45 mod_tls/2.4.3[8609]: using default OpenSSL verification locations (see $SSL_CERT_DIR environment variable) Aug 05 16:33:45 mod_tls/2.4.3[8609]: SSL/TLS required but absent for authentication, denying USER command Aug 05 16:33:45 mod_tls/2.4.3[8610]: using default OpenSSL verification locations (see $SSL_CERT_DIR environment variable) Aug 05 16:34:48 mod_tls/2.4.3[8611]: using default OpenSSL verification locations (see $SSL_CERT_DIR environment variable) Aug 05 16:34:48 mod_tls/2.4.3[8611]: TLS/TLS-C requested, starting TLS handshake Aug 05 16:34:48 mod_tls/2.4.3[8611]: client supports secure renegotiations Aug 05 16:34:48 mod_tls/2.4.3[8611]: TLSv1/SSLv3 connection accepted, using cipher DHE-RSA-AES256-GCM-SHA384 (256 bits) Aug 05 08:35:11 mod_tls/2.4.3[8611]: Protection set to Private Aug 05 08:35:11 mod_tls/2.4.3[8611]: starting TLS negotiation on data connection Aug 05 08:35:11 mod_tls/2.4.3[8611]: TLSv1/SSLv3 renegotiation accepted, using cipher DHE-RSA-AES256-GCM-SHA384 (256 bits) Aug 05 08:35:11 mod_tls/2.4.3[8611]: client reused SSL session for data connection Aug 05 08:35:11 mod_tls/2.4.3[8611]: TLSv1/SSLv3 data connection accepted, using cipher DHE-RSA-AES256-GCM-SHA384 (256 bits)
