dd if=/dev/zero of=/usr/swap0 bs=1m count=128

chmod 0600 /usr/swap0

echo ‘md99 none swap sw,file=/usr/swap0 0 0’ >> /etc/fstab

swapon -aq

cd /usr/ports/sysutils/fusefs-ntfs && make BATCH=yes install clean
or
pkg install fusefs-ntfs
Then add to /boot/loader.conf

fuse_load=”YES”
Now run it:

/usr/local/etc/rc.d/fusefs start

Now – make dir for NTFS partition, for example:

mkdir /mnt/ntfs

Now – you can mount your NTFS in rw mode:

ntfs-3g -o rw,locale=zh_CN.UTF-8 /dev/ada0s3 /mnt/ntfs

After all – add to /etc/fstab:

/dev/ada0s1 /mnt/ntfs ntfs-3g rw,locale=zh_CN.UTF-8, mountprog=/usr/local/bin/ntfs-3g,uid=1001,gid=1001,late 0 0

http://pkg.freebsd.org/ 在这个页面上可以看到：

pkg0.bme.freebsd.org
pkg0.nyi.freebsd.org
pkg0.twn.freebsd.org
pkg0.ydx.freebsd.org

第一步：ee /ec/rc.conf中加入

sendmail_enable=”NO”

sendmail_submit_enable=”NO”

sendmail_outbound_enable=”NO”

sendmail_msp_queue_enable=”NO”
killall sendmail

第二步：安装ssmtp:

pkg install ssmtp

ee /etc/mail/mailer.conf

sendmail /usr/libexec/sendmail/sendmail
send-mail /usr/libexec/sendmail/sendmail
mailq /usr/libexec/sendmail/sendmail
newaliases /usr/libexec/sendmail/sendmail
hoststat /usr/libexec/sendmail/sendmail
purgestat /usr/libexec/sendmail/sendmail
to

sendmail /usr/local/sbin/ssmtp
send-mail /usr/local/sbin/ssmtp
mailq /usr/libexec/sendmail/sendmail
newaliases /usr/libexec/sendmail/sendmail
hoststat /usr/libexec/sendmail/sendmail
purgestat /usr/libexec/sendmail/sendmail
第三步：创建ssmtp用户

pw useradd ssmtp -g nogroup -h – -s /sbin/nologin -d /nonexistent -c “sSMTP pseudo-user”

第四步：

cd /usr/local/etc/ssmtp

chown ssmtp:wheel .

chmod 4750 .

第五步：

cp ssmtp.conf.sample ssmtp.conf

chown ssmtp:wheel . ssmtp.conf

chmod 640 ssmtp.conf

第六步：编辑ssmtp.conf文件

mailhub=smtp.exmail.qq.com:465
UseTLS=YES
AuthUser=from@mydomain.com
AuthPass=123456
FromLineOverride=YES
Hostname=serverkvm
RewriteDomain=exmail.qq.com
Root=postmaster
cp revaliases.sample revaliases

root:from@mydomain.com:smtp.exmail.qq.com:465
from:from@mydomain.com:smtp.exmail.qq.com:465
chown ssmtp:nogroup /usr/local/sbin/ssmtp
chmod 4555 /usr/local/sbin/ssmtp

测试：echo “test” | mail -v -s “test mail” your_mail@domain.com

cd /usr/ports/net/shadowsocks-libev

make install clean;rehash

ee /etc/rc.conf 加入

shadowsocks_libev_enable=”YES”
shadowsocks_libev_flags=”-c /usr/local/etc/shadowsocks-libev/config.json”

在/usr/local/etc/shadowsocks-libev/config.json中加入

{
“server”:”136.0.16.99″,
“server_port”:1234,             //服务端端口
“local_address”: “127.0.0.1”,
“local_port”:4321,                 //客户端端口
“password”:”password”,      //客户端连接密码
“timeout”:300,
“method”:”aes-256-cfb”     //加密方式
}

然后客户端，在本地，用config.json文件内容对shadowsocks-gui进行相应配置并运行客户端，

shadowsocks-gui下载地址：http://sourceforge.net/projects/shadowsocksgui/files/dist/

最后设置浏览器代理。Chrome 推荐使用 SwitchySharp 切换代理设置。把浏览器代理设为下列参数即可：

协议: socks5

地址: 127.0.0.1

端口: 你填的 local_port

service shadowsocks-libev restart

ok应该可以科学上网了

1、首先安装需要配置好apache2/mysql/php等服务！前面有过笔记。

2、安装pure-ftpd

cd /usr/ports/ftp/pure-ftpd/

make with_language=simplified-chinese install clean;rehash

安装时，会有选择项；勾选：

MYSQL Support for users in mysql database

PRIVSEP Enable privileges separation

PERUSERLIMITS Per-user concurrency limits

THROTTLING Bandwidth throttling

BANNER Show pure-ftpd welcome upon session start

UTF8 Support for charset conversion (expreimental)

安装完成后 添加pureftpd_enable=”YES”到/etc/rc.conf文件中。

3、创建MySQL数据库，登陆mysql

INSERT INTO mysql.user (Host, User, Password, Select_priv, Insert_priv, Update_priv, Delete_priv, Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv, File_priv, Grant_priv, References_priv, Index_priv, Alter_priv, ssl_cipher, x509_issuer, x509_subject)

VALUES(‘localhost’,’ftp’,PASSWORD(‘tmppasswd’),’Y’,’Y’,’Y’,’Y’,’N’,’N’,’N’,’N’,’N’,’N’,’N’,’N’,’N’,’N’, Hex(“”), Hex(“”), Hex(“”));

FLUSH PRIVILEGES;

CREATE DATABASE ftpusers;

USE ftpusers;

drop table if exists ftpusers.admin;

CREATE TABLE ftpusers.admin (

Username varchar(35) NOT NULL default ”,

Password char(32) binary NOT NULL default ”,

PRIMARY KEY (Username)

) ;

—

— Data for table ‘admin’

—

INSERT INTO ftpusers.admin VALUES (‘Administrator’,MD5(‘tmppasswd’));

—

— Table structure for table ‘users’

—

drop table if exists ftpusers.users;

CREATE TABLE ftpusers.users (

`User` varchar(16) NOT NULL default ”,

`Password` varchar(32) binary NOT NULL default ”,

`Uid` int(11) NOT NULL default ’14’,

`Gid` int(11) NOT NULL default ‘5’,

`Dir` varchar(128) NOT NULL default ”,

`QuotaFiles` int(10) NOT NULL default ‘500’,

`QuotaSize` int(10) NOT NULL default ’30’,

`ULBandwidth` int(10) NOT NULL default ’80’,

`DLBandwidth` int(10) NOT NULL default ’80’,

`Ipaddress` varchar(15) NOT NULL default ‘*’,

`Comment` tinytext,

`Status` enum(‘0′,’1’) NOT NULL default ‘1’,

`ULRatio` smallint(5) NOT NULL default ‘1’,

`DLRatio` smallint(5) NOT NULL default ‘1’,

PRIMARY KEY (`User`),

UNIQUE KEY `User` (`User`)

) ;

—

— Data for table ‘users’

—

INSERT INTO ftpusers.users VALUES (‘ftpuser_1’,MD5(‘tmppasswd’),65534, 31, ‘/usr’, 100, 50, 75, 75, ‘*’, ‘Ftp user (for example)’, ‘1’, 0, 0);

配置pure-ftpd.conf

cp /usr/local/etc/pure-ftpd.conf.sample pure-ftpd.conf

编辑pure-ftpd.conf文件 ee pure-ftpd.conf

MySQLConfigFile /usr/local/etc/pureftpd-mysql.conf

CreateHomeDir yes

DisplayDotFiles no

保存退出

配置pureftpd-mysql.conf

cd /usr/local/etc/

fetch http://machiel.generaal.net/files/pureftpd/v2.x/pureftpd-mysql.conf

或者自己网站上镜像下载

/usr/local/etc/rc.d/pure-ftpd restart

安装User manager for PureFTPd

cd /usr/ports/www/usermanager/

make install clean;rehash

以上全部正确安装完毕后：进入ftp目录下载

http://machiel.generaal.net/files/pureftpd/ftp_v2.1.tar.gz或自己网站镜像

解压后http://ip/ftp/install.php安装即可。

Step [1 – 7]

This configuration script has carried out a few checks to see if everything is ready to start the configuration.

Checking if config.php exists OK!

Checking if config.php is writable OK!

Checking if PHP Extension MYSQL is enabled OK!

Checking if PHP Extension PCRE is enabled OK!

Checking if PHP Extension POSIX is enabled OK!

Checking if PHP Extension SESSION is enabled OK!

Please choose your configuration type:.选择New installation,create a new database.

Step [3 – 7]输入正确的root用户和root的密码。

Settings MySQL database.直接按默认设置(要是你改过密码，就输入你的密码)

Step [4 – 7]语言选择中文，选择Quota support，Ratio support(上传下载比可以选择或不选择)按Save按钮保存配置文件，然后点Setp5进行下一步。

Step [5 – 7]这里你可以更改管理员Administator的密码，也可以创建一个自己的帐号代替Administrator

Step [6 – 7]系统有一些提示，说需要编辑那2个配置文件，因为前面已经编辑过了。所以直接下一步。

Step [7 – 7]恭喜你安装完成了。建议把install.php文件更改一下名称

解决方法:

开机后进入单机模式,选择4

或者是输入#boot -s

然后执行

/sbin/fsck

/sbin/mount -a

重新启动ok

服务器上的一些统计数据：

1)统计80端口连接数

netstat -nat|grep -i “80”|wc -l

1

2）统计httpd协议连接数

ps -ef|grep httpd|wc -l

1

3）、统计已连接上的，状态为“established’

netstat -na|grep ESTABLISHED|wc -l

2

4)、查出哪个IP地址连接最多,将其封了.

netstat -na|grep ESTABLISHED|awk ‘{print $5}’|awk -F: ‘{print $1}’|sort|uniq -c|sort -r +0n

netstat -na|grep SYN|awk ‘{print $5}’|awk -F: ‘{print $1}’|sort|uniq -c|sort -r +0n

netstat快速查看一下TCP连接情况

netstat -n | awk ‘/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}’

通过man netstat可以了解SYN_RCVD的意义。SYN_RCVD表示当前未完成的TCP SYN队列

用命令：

# netstat -an | grep SYN | wc -l

$netstat -an | grep SYN_RECV | wc

97 582 7857

$netstat -an | grep 80 | wc

916 5500 74164

vi /etc/rc.conf

以下是我在虚拟机中的一个绑定多IP示例：

# Created: Sat Apr 10 17:06:56 2010

# Enable network daemons for user convenience.

# Please make all changes to this file, not to /etc/defaults/rc.conf.

# This file now contains just the overrides from /etc/defaults/rc.conf.

# — sysinstall generated deltas —

ifconfig_em0=”inet 192.168.245.11 netmask 255.255.255.0″

gateway_enable=”NO”

defaultrouter=”192.168.245.2″

hostname=”192.168.245.11″

ifconfig_em0=”inet 192.168.245.14 netmask 255.255.255.0″

ifconfig_em0_alias0=”inet 192.168.245.15 netmask 255.255.255.0″

ifconfig_em0_alias1=”inet 192.168.245.16 netmask 255.255.255.0″

ifconfig_em0_alias2=”inet 192.168.245.17 netmask 255.255.255.0″

defaultrouter=”192.168.245.2″

hostname=”192.168.245.11″

sshd_enable=”yes”

最后执行如下命令，让rc.conf立即生效

# sh /etc/rc

今天在FreeBSD用dmesg命令查看信息时，发现最后几行出现了错误 提示信息：

/usr was not properly dismounted
/tmp was not properly dismounted
/var was not properly dismounted

几经周折，终于解决了，解决方法如下：

shutdown -h now /halt/reboot/
