If you are unfortunately working on a JUNOS chassis cluster that does not have the out-of-band management patched (fxp0) then you must use an alternate way to connect to specific nodes and copy files. You are able to copy files and login from to the non active node via the following methods.
To copy files or log in JUNOS gives you the following options:
Copy files from one node to another
[plain]
Copy Method A, using CLI:
> file copy /var/tmp/abc.log node1:/var/log/
Copy Method B, using shell, follow the commands in order:
> start shell user root
% rcp -T /var/tmp/abc.log node1:/var/log/
[/plain]
Ref link http://kb.juniper.net/InfoCenter/index?page=content&id=KB17410
Login from node0 to node1
The command mentioned does not work on 3k and 5k devices.
[plain]
% rlogin -Jk -T node1 (This is shell command)
[/plain]

So application identification / firewall / secure has made it way to the branch. This is awesome news. So I have managed to obtain a 30 day trial to see how it performs on my home SRX100. With ym simple rule base I have seen 1ms increase in my latency!!
After adding the license you can now perform the following:
Install Application identification
request services application-identification download
Check the status:
- request services application-identification download status
Application package 1980 is installed successfully.
Create a Application Ruleset
All that is ahppening here is youtube is BLOCKED, everything else is allowed.
[plain]
set security application-firewall rule-sets block-webtraffic rule youtube match dynamic-application junos:YOUTUBE
set security application-firewall rule-sets block-webtraffic rule youtube then deny
set security application-firewall rule-sets block-webtraffic default-rule permit
[/plain]
Add to a security policy:
There is now the 'application-firewall' settings to apply to policies ...
cooper@noona-gw# set security policies from-zone trust to-zone untrust policy trust-to-untrust then permit application-services ?
Possible completions:
> application-firewall Application firewall services
+ apply-groups Groups from which to inherit configuration data
+ apply-groups-except Don't inherit configuration data from these groups
gprs-gtp-profile Specify GPRS Tunneling Protocol profile name
gprs-sctp-profile Specify GPRS stream control protocol profile name
idp Intrusion detection and prevention
redirect-wx Set WX redirection
reverse-redirect-wx Set WX reverse redirection
> uac-policy Enable unified access control enforcement of policy
utm-policy Specify utm policy name
Example Policy:
[plain]
set security policies from-zone trust to-zone untrust policy trust-to-untrust match source-address any
set security policies from-zone trust to-zone untrust policy trust-to-untrust match destination-address any
set security policies from-zone trust to-zone untrust policy trust-to-untrust match application any
set security policies from-zone trust to-zone untrust policy trust-to-untrust then permit application-services application-firewall rule-set block-webtraffic
set security policies from-zone trust to-zone untrust policy trust-to-untrust then log session-init
set security policies from-zone trust to-zone untrust policy trust-to-untrust then log session-close
[/plain]
TODO: Play with 'application-tracking'. Will update blog post once I have.
So it's that simple ... Application firewalling is now accross the whole SRX range ... win.

Do you have Junos devices? If you do, excellent choice. Do you have MiToken? Once again, love your work there. If you don't have MiToken, it's a plug-in to the M$ IAS/NPS servers that allows mutiple types of hard and soft tokens to be used allowing secure OTPs with dual factor authentication with your Active Directory domain(s).
This post will guide you though configuring Junos to use MiToken for two factor authentiucation to help hardern your Junos devices.
For more information on MiToken visit mi-token.com.
This configuration has been tested with Junos11.1r3.5, Junos is a registered trademark of Juniper Networks.
Junos Device Config:
Now go jump into Junos configuration mode and set the following:
[text]
# Add radius to the password auth order
set system authentication-order radius
set system radius-server x.x.x.x port 1812
set system radius-server x.x.x.x secret "SECRET"
set system radius-server x.x.x.x timeout 10
set system radius-server x.x.x.x retry 2
set system radius-server x.x.x.x source-address x.x.x.x
# Block everyone access by default
set system login user remote full-name Radius-User
set system login user remote class unauthorized
# Create users who should get access
set system login user john full-name "John Smith"
set system login user john class super-user
[/text]
MiToken / NPS Configuration:
Now lets configure the MiToken side to accept radius packets from our Junos device(s). The only down side to MiToken is it runs on Windows :-(.
1) Define a Radius client in NPS
Right click on radius clients and choose 'New RADIUS Client'
2) Define a connection request policy
Set up your policy to identify your Junos devices ... For more information refer to the MiToken Admin guide.
This step is optional. You do not have to require Windows Authentication to be active - This would take you back to single factor OTP auth
3) Enable MiToken on the connection request policy for Junos devices
4)
Enjoy you radius dual factor authentication. Your auditors and boss will now love you. Hit them up for a raise.
5)
Send some praise Cooper's way 🙂

So a co-worker and I spent some time playing around with JunOS 11's (I believe it came in with 11 - correct me if wrong) reth's ability to now be LACP interfaces, as well as just plain redundant. It was not immediately clear how the switch was required to be set up in order to facilitate this new, awesome feature.
- This was used with a ex4200 virtual chassis cluster and SRX Chassis Cluster -
Here is how we got it happily working (assuming you have a chassis cluster up and running):
SRX Config:
set interfaces ge-2/0/0 gigether-options redundant-parent reth1
set interfaces ge-2/0/1 gigether-options redundant-parent reth1
set interfaces ge-2/0/2 gigether-options redundant-parent reth1
set interfaces ge-2/0/3 gigether-options redundant-parent reth1
set interfaces ge-11/0/0 gigether-options redundant-parent reth1
set interfaces ge-11/0/1 gigether-options redundant-parent reth1
set interfaces ge-11/0/2 gigether-options redundant-parent reth1
set interfaces ge-11/0/3 gigether-options redundant-parent reth1
set interfaces reth1 redundant-ether-options redundancy-group 1
set interfaces reth1 redundant-ether-options lacp passive
EX Config:
set interfaces ge-0/0/0 ether-options 802.3ad ae1
set interfaces ge-0/0/1 ether-options 802.3ad ae2
set interfaces ge-0/0/2 ether-options 802.3ad ae1
set interfaces ge-0/0/3 ether-options 802.3ad ae2
set interfaces ge-1/0/0 ether-options 802.3ad ae2
set interfaces ge-1/0/1 ether-options 802.3ad ae1
set interfaces ge-1/0/2 ether-options 802.3ad ae2
set interfaces ge-1/0/3 ether-options 802.3ad ae1
set interfaces ae1 aggregated-ether-options lacp active
set interfaces ae2 aggregated-ether-options lacp active
Now we have LACP bandwidth and redundancy - Either the switch or SRX can die, in theory.
* Have not tested the failover yet - But will before this set up goes to production - Will update the post *

So I am a very large geek, and proud of it. It hurt to walk past a cupboard at work knowing there was 30+ Cisco PIX 501 firewalls sitting in there collecting dust. One day it dawned on me, I wonder how crap internet would be sitting behind 30 of those slow ass god awful to use and configure firewalls. So here are the results:
Network Diagram
(Click for larger image)
Sample PIX 501 conf:
[plain]
hostname fwX
password cisco
enable password cisco
domain-name cooperlees.com
ip address inside 10.N.0.1 255.255.255.0
ip address outside 10.N1.0.2 255.255.255.0
interface ethernet0 auto
interface ethernet1 100full
route outside 0 0 10.N1.0.1
nat (inside) 1 10.N.0.0 255.255.255.0
global (outside) 1 interface
access-list outbound permit any any
access-group outbound in interface inside
access-list ping_acl permit icmp any any
access-group ping_acl in interface outside
[/plain]
