• Generate CA files

  A. setting and folder

    1. Edit "C:\Apache2.2\conf\openssl.cnf" with below command. To make sure "dir" setting

         "C:\Program Files\Windows NT\Accessories\wordpad.exe" C:\Apache2.2\conf\openssl.cnf

          [ CA_default ]

          dir = ./ssl       # Where everything is kept

    2. Create ssl folder in "C:\Apache2.2\bin".   Folder "C:\Apache2.2\bin\ssl" will be placed some files with regard to SSL/CA files.
    3. Create a empty file "index.txt" in in folder "C:\Apache2.2\bin\ssl"
    4. Create "serial" file in folder "C:\Apache2.2\bin\ssl", filling "01" in the file.
    5. Create a folder "newcerts" in "C:\Apache2.2\bin\ssl"

  B. Create "ca.crt" CA file
    6. In dos command windows, change working direction to "C:\Apache2.2\bin"
    7. hit "openssl genrsa -des3 -out ssl/ca.key 1024"     ,and provide a pass phrase, like "654321"
    8. hit "openssl req -config ../conf/openssl.cnf -new -key ssl/ca.key -out ssl/ca.csr"
    9. hit "openssl x509 -days 3650 -req -signkey ssl/ca.key -in ssl/ca.csr -out ssl/ca.crt"

  C. Create "server.crt" CA file
    9. hit "openssl genrsa -out ssl/server.key 1024"
    10. hit "openssl req -config ../conf/openssl.cnf -new -key ssl/server.key -out ssl/server.csr"
    11. hit "openssl ca -config ../conf/openssl.cnf -days 3650 -cert ssl/ca.crt -keyfile ssl/ca.key -in ssl/server.csr -out ssl/server.crt"

  D. Creating a client certificate pkcs12 file (.p12)
    12. openssl pkcs12 -export -name "Client Certificate" -in ssl\ca.crt -inkey ssl\ca.key -out ssl\ca.p12
    13. provide a import pass phrase that is using for import pkcs12 file on PC side.

E. copy ssl folder to ...
    14. There are 12 files and 1 folder in "C:\Apache2.2\bin\ssl".
    15. copy ssl folder to to "C:\Apache2.2\conf"

• Import pkcs12(.p12) file into web browser

* 比對
$ git diff master
* 產生patch
$ git diff master > xxx.patch

* 放棄修改, 恢復到目前的commit
$ git checkout -f

* 列出commit
$ git log --pretty=oneline

defaults
{
        instances = 60
        log_type = SYSLOG authpriv
        log_on_success = HOST PID
        log_on_failure = HOST
        cps = 25 30
}
includedir /etc/xinetd.d
