Generating a Certificate Signing Request (CSR) using Apache (with mod_ssl) & OpenSSL

Generating a Certificate Signing Request (CSR) using Apache (with mod_ssl) & OpenSSL

To generate your CSR, you will need to log in to your server and use the OpenSSL software to generate a CSR and private key.

1. Log in to your server, and enter the following command:

openssl req -nodes -newkey rsa:2048 -keyout myserver.key -out server.csr

This will generate two files: a CSR called 'server.csr' and a 2048-bit private key called 'myserver.key'.

2. You will be prompted to enter some information for your CSR:

Country Name (2 letter code) [AU]: GB
State or Province Name (full name) [Some-State]: Yorks
Locality Name (eg, city) []: York
Organization Name (eg, company) [Internet Widgits Pty Ltd]: MyCompany Ltd
Organizational Unit Name (eg, section) []: IT
Common Name (eg, YOUR name) []: mysubdomain.mydomain.com
Email Address []:

Please enter the following 'extra' attributes to be sent with your certificate request

A challenge password []:
An optional company name []:

The 'CN' field (Common Name) is where you should enter the fully qualified domain name of the website you require the certificate for.
Note: for wildcard certificates, the Common Name should be in the format: *.mydomain.com

3. Your CSR is now generated. Open the 'server.csr' file with a text-editor and copy and paste the contents into the enrollment form when requested.

Notes:
The 'myserver.key' file should be kept secure (e.g. readable only by root on linux systems).

Removing the '-nodes' option from the openssl command will request a password and encrypt the private key. This can increase security, but note that the password will be required each time Apache is restarted.

EV certificates require a minimum of a 1024-bit keysize if valid before 2011, and 2048-bit if they are valid into 2011. We recommend that a 2048-bit keysize is the minimum used for all certificates.

The two-letter 'Country Name' field must be the ISO-3166 standard country code. Please note that 'GB' is correct for Great Britain, not 'UK'. A complete list can be found here: http://www.iso.org/iso/country_codes.htm

Limitasi Mikrotik port SMTP dan POP3 pada jaringan lokal

Limitasi Mikrotik port SMTP dan POP3 pada jaringan lokal. Di bawah ini configurasi port SMTP(25) dan POP3(110) pada mikrotik.

1. Buat mangle untuk SMTP dan POP3
SMTP:
    ip firewall mangle add action=mark-packet chain=prerouting dst-port=25 protocol=tcp new-packet-mark=smtp_pack passthrough=yes comment=Limitasi_SMTP


POP3:

    ip firewall mangle add action=mark-packet chain=prerouting dst-port=110 protocol=tcp new-packet-mark=pop3_pack passthrough=yes comment=Limitasi_POP3


2. Buat limitasi menggunakan "Queue Tree"

SMTP:

    queue tree add name=smtp-q parent=global-out packet-mark=smtp_pack queue=default priority=8 max-limit=256000


POP3:

    queue tree add name=pop3-q parent=global-out packet-mark=pop3_pack queue=default priority=8 max-limit=256000



Pada configurasi diatas dibatasi untuk SMTP dan POP 256kb bandwidth.
Dengan demikian limitasi port SMTP dan POP3 selesai.

How to perform a Cisco router password recovery without losing your configuration.

How to perform a Cisco router password recovery without losing your configuration.

In order to perform a password recovery, you will need to reboot the router a couple of times.  This means downtime, but it is a good sacrifice to make in order to get your passwords reset.

First, hook up the DB9 end of the standard light blue serial cable to your serial port.  The other end of the cable should plug into the port labeled “Console” on the back of the Cisco router.  If you do  not have a serial port, then you'll need to go purchase a USB-to-serial adapter cable and install it on your computer.

Now that your hardware is connected, establish a serial connection with the router.
The settings you need are:
Baud: 9600
Data bits: 8
Parity: No
Stop bits: 1
Flow Control: None

On Windows, I use putty for this connection.  Yes, putty can be used to make serial connections as well as telnet/ssh.  Hyperterminal works great as well.  On Linux, I use minicom and on FreeBSD/OpenBSD, I use cu (cu -s 9600 -l /dev/cuad0).

Reboot the router and press the Break key to interrupt the boot sequence.
For break key sequences, refer to this Cisco link: http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note0...

Type confreg 0x2142.  This tells the router to bypass NVRAM during bootup.  In other words, your existing configuration won't be loaded.  The good news is that it won't be deleted either.

Type reset to reboot the router.  Answer No when prompted to run setup.

Type copy start run.  This loads your startup configuration into memory.  Now, if you type a show run config, you'll see the router configuration.  Also, you should notice that your router name is now in the prompt instead of the default “Router”.

Change the enable secret - “enable secret new_password”

Change the register back to 0x2102:
config-register 0x2102

When the router reboots it will load the old configuration with the new password.

Save the password so that it will be persistent during reboots, type copy run start

Reboot the router by typing reload at the enable prompt.
