Summary:
Editing the Windows "hosts" file to override the network DNS resolution
Problem or Goal:
How to edit the "hosts" file on windows machine, this overrides the network DNS answer.
Cause:
In most cases, especially while testing new website installs on hostgator cpanel for domain names that are already in production, i find myself in a situation where i have to edit the "hosts" file on my PC to point to a hostgator server. when am done testing, i delete the entry i had made in the hosts file and point the domain to the hostgator DNS servers.
This helps me to test the site locally on my laptop without interfering with the live website.
Solution:
File Location: C:\Windows\System32\drivers\etc

Configuring TACACs+ for Juniper Routers and Switches with virtual routing instances
Summary:
Today i found myself in a situation where i have to add some juniper switches (EX4200s and EX4500s) to our TACACs+ server, for the switches where the remote access IP was configured on the management interface (me0) or any other interface but accessible from the global routing table (inet.0) i didn't face any issues.
However, for switches were the operation and maintenance IP was configured within a routing instance, i had issues because there is no routing-instance specific configuration for TACACs+
TACACs+ server has to be reachable from the global routing table.
Problem or Goal:
Configuring TACACs on a switch with routing instances and VRFs
Cause:
TACACs+ server has to be reachable from the global routing table.
Solution:
Instead of using vlan routed interfaces or the normal interfaces bound to a routing instance, use the management interface (me0).
Juniper has an interface dedicated for management that uses the control plane and is useful for out-of-band management.
Example:
If you have virtual chassis enabled:
set interfaces vme unit 0 family inet address 10.172.2.2/24
if you are working on a single switch without virtual chassis:
set interfaces me0 unit 0 family inet address 10.172.2.2/24
You will need to connect the MGT interfaces to your LAN network.
You also need to add this part of configuration on the switch according to your TACACs server details:
set system login user remote full-name "Tacacs+ System User"
set system login user remote uid xxxx
set system login user remote class super-user
set system authentication-order tacplus
set system authentication-order password
set system tacplus-server 10.0.X.X port 49
set system tacplus-server 10.0.X.X secret tacacs_secret_key
set system tacplus-server 10.0.X.X single-connection
set system tacplus-server 10.0.X.X source-address 10.172.2.2
set system accounting events [ change-log interactive-commands login ] destination tacplus server 10.0.X.X
Don't forget to create a failover local login incase TACACs+ is offline:
set system login user admin uid xxxx
set system login user admin class super-user
set system login user admin authentication plain-text-password
Problem Solved?
Yes
