mldonkey-server: 2.9.2-2ubuntu0.1

1.安装

sudo apt-get install mldonkey-server

2.速度设置

网上有很多，有一些是不正确的。只要留意一下说明就可以了。这里的环境是4M的带宽，公网IP。主要设置如下：

max_hard_upload_rate = 10

    (* The maximal download rate you can tolerate on your link in kBytes/s (0 = no limit)
      The limit will apply on all your connections (clients and servers) and both
      control and data messages. Maximum value depends on max_hard_upload_rate:
      >= 10    -> unlimited download
      < 10 > 3 -> download limited to upload * 4
      < 4      -> download limited to upload * 3 *)
 max_hard_download_rate = 400

    (* Second maximal upload rate for easy toggling (use bw_toggle) *)
 max_hard_upload_rate_2 = 10

    (* Second maximal download rate for easy toggling (use bw_toggle) *)
 max_hard_download_rate_2 = 200

    (* Maximal number of opened connections *)
 max_opened_connections = 50

    (* Amount of indirect connections in percent (min 30, max 70) of max_opened_connections *)
 max_indirect_connections = 30

3.定时改变下载速度

 每天1点下载速度设置为400KB/s，8点设置为200KB/s。在/var/lib/mldonkey/download.ini 中的calendar直接写入：

 calendar = [
  ([
      0;
      1;
      2;
      3;
      4;
      5;
      6;], [
      1;], bw_toggle);
  ([
      0;
      1;
      2;
      3;
      4;
      5;
      6;], [
      8;], bw_toggle);]
 

1. SYSTEM

此种模式适合希望在台式机或笔记本上使用Eucalyptus的用户设置。在节点VM实例启动前，Euca会为每个实例分配一个随机MAC地址，并且通过节点本地的Xen桥接程序将虚拟实例的以太网设备与物理以太网连接。

2. STATIC

适合拥有MAC/IP资源池并随时想为虚拟机实例分配MAC/IP地址对的用户。当虚拟机实例化的时候，Euca会以静态方式开启DHCP服务器取出下一个IP/MAC地址对。并通过节点本地的Xen桥接程序将虚拟实例的以太网设备与物理以太网连接。

3. MANAGED

用户自定义一个自命名的网络，虚拟机实例从这个网络中获得IP，与STATIC模式类似，用户可以对一个静态IP槽进行管理和分配，另外，管理员可以对某自定义网络定义一个外部规则并运用于属于此网络的所有实例。这一部分功能与Amazon的弹性IP机制类似。

4. MANAGED-NOVLAN

提供了MANAGED mode的动态IP和自定义网络的特性，但不支持虚拟局域网之间的隔离
 

Gave up waiting for root device.Common programs:
—Boot args(cat /proc cmdline)
—Check rootdelay=(did the system wait long enough?)
—Check root=(did the system wait for the right device?)
—Missing modules (cat /proc/modules: ls /dev)

没理由那么杯具吧。按照提示来检查：

1.Boot args

安装好之后没有修改过grub.cfg，也没有重启，估计不是这个问题。

2.rootdelay

难道服务器启动慢？新到的R525，双U，8G内存，没理由啊。不会是因为加了个LSI HBA卡就这样吧？算了，还是加上延迟来试试。

使用server 的安装光盘启动，选择 Rescure a broken system，像装系统那样一步步进行，最后在选择执行shell 位置的时候选择原来系统的根/。由于之前把/boot单独分来出来，这里挂载一下并修改/boot/grub/grub.cfg为可写，然后在 kernel        /boot/vmlinuz-2.6.32-24-generic root=UUID=7e4d787a-8081-4f79-b2c4-9945912697a4 ro quiet 后面加上 rootdelay=60 ，用sed -i 's/quiet/quiet\ rootdelay=60/' /boot/grub/grub.cfg 可直接替换，不熟悉就用vi吧， rootdelay=60表示延迟60秒。重启！

Lucky ，搞掂！

3.后面的就不用检查了^_^

参考：https://help.ubuntu.com/community/UEC/CDInstall

安装完成之后最好配置一下dhcp3-server，以免出现重启后运行实例时无法自动获取到ip。

解释如下：

 参考自：www.vmware.com/pdf/vmware_timekeeping.pdf

1.安装需要用到的包
sudo apt-get install ssl-cert

2.证书默认是1个月的有效期，这里是测试用，改成10年。
sudo sed -i -e 's/keyout $output/keyout $output -days 3650/' /usr/sbin/make-ssl-cert

3.建立目录，并生成证书
sudo mkdir /etc/apache2/ssl
sudo make-ssl-cert /usr/share/ssl-cert/ssleay.cnf /etc/apache2/ssl/apache.pem

过程要求输入：
Country Name (2 letter code) [GB]:CN
State or Province Name (full name) [Some-State]:GD
Locality Name (eg, city) []:GZ
organization Name (eg, company) [Internet Widgits Pty Ltd]:3gcomet
organizational Unit Name (eg, section) []:3gcomet.com
Common Name (eg, YOUR name) []:3gcomet.com
Email Address []:comet#3gcomet.com

4.启用 ssl 模块
sudo a2enmod ssl
确认一下443端口启用了：
cat /etc/apache2/ports.conf

<IfModule mod_ssl.c>
Listen 443
</IfModule>

5.建立站点文件，复制默认的，稍作修改：
sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/ssl

修改 /etc/apache2/sites-available/ssl ：
因为ssl用的是443端口，所以把80端口改成443，在<VirtualHost *:443>下面加上以下两行
SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.pem

6.启用ssl站点配置
sudo a2ensite ssl

7.重启apache2
/etc/init.d/apache2 restart

1. Free Redistribution
The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.

2. Source Code
The program must include source code, and must allow distribution in source code as well as compiled form. Where some form of a product is not distributed with source code, there must be a well-publicized means of obtaining the source code for no more than a reasonable reproduction cost preferably, downloading via the Internet without charge. The source code must be the preferred form in which a programmer would modify the program. Deliberately obfuscated source code is not allowed. Intermediate forms such as the output of a preprocessor or translator are not allowed.

3. Derived Works
The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.

4. Integrity of The Author's Source Code
The license may restrict source-code from being distributed in modified form only if the license allows the distribution of "patch files" with the source code for the purpose of modifying the program at build time. The license must explicitly permit distribution of software built from modified source code. The license may require derived works to carry a different name or version number from the original software.

5. No Discrimination Against Persons or Groups
The license must not discriminate against any person or group of persons.

6. No Discrimination Against Fields of Endeavor
The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.

7. Distribution of License
The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties.

8. License Must Not Be Specific to a Product
The rights attached to the program must not depend on the program's being part of a particular software distribution. If the program is extracted from that distribution and used or distributed within the terms of the program's license, all parties to whom the program is redistributed should have the same rights as those that are granted in conjunction with the original software distribution.

9. License Must Not Restrict Other Software
The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open-source software.

10. License Must Be Technology-Neutral
No provision of the license may be predicated on any individual technology or style of interface.
