解释如下：

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

tftp 192.168.1.2 192.168.1.200 rgnos.bin -main -go 

其中192.168.1.2是指定路由的ip，192.168.1.200是tftp服务器的ip，rgnos.bin是路由的OS。升级过程不要断电或重启路由。

升级后的版本如下：

R1762#sh ver
System description      : Ruijie Router(R1762) by Ruijie Network
System start time       : 2010-6-29 15:18:14
System hardware version : 1.3
System software version : RGNOS 10.2.00(2b35), Release(67341)
System boot version     : 10.2.67341
System serial number    : 1234942570132

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

8.通过https访问
https://ServerIP

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.
