JUNOS : New Features - ALG Overview

An Application Layer Gateway (ALG) is a software component that is designed to manage specific protocols such as Session Initiation Protocol (SIP) or FTP on Juniper Networks devices running JUNOS Software. The ALG module is responsible for Application-Layer aware packet processing.
ALG functionality can be triggered either by a service or application configured in the security policy:
  • A service is an object that identifies an application protocol using Layer 4 information (such as standard and accepted TCP and UDP port numbers) for an application service (such as Telnet, FTP, SMTP, and HTTP).
  • An application specifies the Layer 7 application that maps to a Layer 4 service.
A predefined service already has a mapping to a Layer 7 application. However, for custom services, you must link the service to an application explicitly, especially if you want the policy to apply an ALG.
ALGs for packets destined to well-known ports are triggered by service type. The ALG intercepts and analyzes the specified traffic, allocates resources, and defines dynamic policies to permit the traffic to pass securely through the device:
  1. When a packet arrives at the device, the flow module forwards the packet according to the security rule set in the policy.
  2. If a policy is found to permit the packet, the associated service type or application type is assigned and a session is created for this type of traffic.
  3. If a session is found for the packet, no policy rule match is needed. The ALG module is triggered if that particular service or application type requires the supported ALG processing.
The ALG also inspects the packet for embedded IP address and port information in the packet payload, and performs Network Address Translation (NAT) processing if necessary. The ALG also opens a gate for the IP address and port number to permit data exchange for the session. The control session and data session can be coupled to have the same timeout value, or they can be independent.

JUNOS : Install Software via CLI from Junos software copied to USB stick

Follow these steps to install the software via the CLI from a USB stick:
  1. Download the Junos upgrade file to the USB stick. 
  2. Locate the USB device ID that Junos is associating to the USB stick:
    user@srx> start shell
    user@srx% ls /dev/

  3. Insert the USB device into the USB slot.  For example, slot 0 would return the following:
    root# umass0: USB USBFlashDrive, rev 2.00/1.00, addr 2
    da0 at umass-sim0 bus 0 target 0 lun 0
    da0: <USB USBFlashDrive 0100> Removable Direct Access SCSI-0 device
    da0: 1.000MB/s transfers
    da0: 980MB (2007040 512 byte sectors: 64H 32S/T 980C)

    Run the following command

    user@srx% ls /dev/

    Locate difference in outputs to locate drive label. (It will usually be da#s1, i.e. da0s1)
  4. Create a mount directory:
    user@srx% mkdir /tmp/usb
  5. Mount the USB to the directory:
    user@srx% mount -t msdosfs /dev/<drivelabel, e.g. #da0s1> /tmp/usb

    Example:
    user@srx% mount -t msdosfs /dev/da0s1 /tmp/usb (there is a space between the label name and /tmp)

    Verify that the USB is mounted to the device:
    root@% pwd
    /cf/root
    root@% cd /var/tmp/usb/
    root@% pwd
    /cf/var/tmp/usb
    root@% ls
    junos-jsr-11.4R5.7-export.tgz
  6. Exit shell and install the software:
    user@srx% exit
    user@srx> request system software add /tmp/usb/<upgrade filename> no-validate no-copy
  7. Upon completion, reboot the SRX:
    user@srx> request system reboot

JUNOS : ACTIVATE YOUR SRX SERIES AND J SERIES FEATURES




Four Easy Steps to Activate Your Juniper Networks Product Features
 



1. Gather your Authorization Code and Device Serial Number.

Authorization Code:

The 16-digit alphanumeric Authorization Code is sent via email in response to your order and is required to generate the license activation key for your SRX Series device. The Authorization Code is required to generate your license key—it is not the actual license key.

Device Serial Number:
The device serial number is a unique 12-digit alphanumeric code used to identify your SRX Series device when generating license keys. You can find the SRX Series device serial number either on the bottom or sides of the unit. You can also find the serial number via the NSM Device Inventory Hardware tab by executing the CLI command, “show chassis hardware,” or through the J-Web Monitor Dashboard.

2. Sign in to the Juniper Networks License Management System at  www.juniper.net/generate_license ,

Select the J Series and SRX Series device link, and follow the instructions in the system user interface.

3. The Juniper License Management System provides you with your license key in one of two ways:

Download your license key to your computer from the Juniper Networks License Management System.

• You receive an email that contains the license key.

4. On the SRX Series Device:

CLI: request system license add terminal > Press Enter >
When prompted, type the license key separating multiple license keys with a blank line > Ctrl-D.

J-Web Interface:
Click Maintain > Licenses and enter the license key in one of the following ways:
In the license File URL box, type the URL for the license key website.

•Or copy the license key text, and paste it into the License Key Text box, separating multiple license keys with a blank line.

• Click OK

JUNOS : Configure System Log

By default, control protocol activity is logged as a separate system log facility, dfc. To modify the filename or level at which control protocol activity is recorded, include the following statements at the [edit syslog] hierarchy level:
[edit syslog]
file dfc.log {dfc any;}
To cancel logging, include the no-syslog statement at the [edit services dynamic-flow-capture capture-group client-name control-source identifier] hierarchy level:
[edit services dynamic-flow-capture capture-group client-name control-source identifier]no-syslog;
