As your phone is often carried than your pc, it's good to have essential software, that can do basic functions in your phone.  It can find information from Google using phone browser, play games, or others function when you need.

Having Windows Mobile smartphone is not just like have a phone, but it's like have a personal computer, in more simple and little form.  It can do many things for you. Although now it's not popular again, but it still has many purpose.

According to release from Juniper website, Juniper now enter mobile security market by releasing Junos Pulse Mobile Security Suite. 

Cited from NSN people blog, new iPhone OS, iOS 4.2, tests by Nokia Siemens Networks have shown that iPhone iOs 4.2 support a technology called Network Controlled Fast Dormancy, which have already introduced into NSN networks. This will cut smartphone signalling down to size.  Basically, the technology makes the network and the handset work together to create the best conditions for smartphones to work quickly, yet have a long battery life and minimize network congestion.

Today internet is rather different with few years ago.  Few years ago, internet is very dependent to Tier 1 ISP.  If you have many Tier 1 IP Transit, you can have better internet access, because more route can you reach with best path. 

Many IP transit now have their own CDN, but it is likely not a free service.  Traditional CDN, like Akamai, are open for ISP to partner with them.

Deleting Statement from JunOS Configuration
Here example for deleting a statement from JunOS Configuration.  I use BGP configuration for example.

Cisco router can be used as VPN server, using L2TP and IPSec, for client from internet accesing private network.

This post will describe how to create VPN Client using L2TP and IPSec on Windows 7.

This post will describe how to create VPN Client using PPTP on Windows 7.

Cisco router can be used as VPN server, using PPTP, for client from internet accesing private network.

As using route reflector is a way simplifying and scaling iBGP configuration, it is recommended to use if you have many routers in your AS.

IBGP require all BGP systems within the AS are a fully meshed, so that any external routing information is redistributed among all routers within the AS. 

Look here for complete TelisSonera BGP Community:

Communities of Tiscali International Network (TINet) - AS3257

---

This is the list of BGP communities that can be set by customers

(after engineering@ip.tiscali.net approval):

• 3257:1030 do not announce to upstream.
• 3257:1031 prepend 1x to upstream.
• 3257:1032 prepend 2x to upstream.
• 3257:1033 prepend 3x to upstream.

Customer Setup Information

Multi-homing with BGP (Border Gateway Protocol) is the practice of connecting to multiple service providers and having simultaneous external BGP peering sessions with each provider. A Multi-homed customer typically owns an Autonomous System Number and exchanges routing table information with two or more upstream Internet
Service Providers (ISPs).

In iBGP, there is a rule to avoid routing loop by not advertise any route receive from other iBGP neighbor.  The rule have consequence that every router in the AS needs peer with all router so every router have routing from other router in the AS.  This is called full mesh configuration. 

This post will shows applications of BGP Community.  It doesn't show deep description about BGP Community.  BGP communities are tags, or attributes that can be attached to BGP prefixes announcement.  Based on that community, policy can be define to do something to that routes.  BGP Communities are descibed in RFC 1997.  According to RFC 1997, BGP Communities describe as a group of destinations which share some common property.  Each autonomus system administrator may define which communities a destination belongs to.  By default, all destinations belong to the general Internet community.  BGP Community have 32 bit value.

Cisco has support EIGRP as PE CPE routing protocol in MPLS VPN.  It is just like another routing protocol using for PE CPE roituing protocol.  The mechanism is common.  EIGRP in PE talk with EIGRP in CPE to exchange routing, then routing receive from CPE is redistribute to MP BGP (multi protocol BGP) running under address family configuration.  EIGRP receive all VPN routing from reditributing form MP BGP (multi protocol BGP) running under address family configuration.

Peer group in a set of BGP neighbor that share some policy.  Policy that can be the same, for example, route-map, filter-list, prefix-list, update-source, route-reflector client.  Peer group can reduce cpu process consumption, also configuration effort.

This procedure will explain how to recover JunOS password.

Olive is PC running JunOS not in Juniper machine. Not like Cisco IOS that have Dynamips as ready to use IOS simulator, there is no ready to use JunOS simulator yet.

IPTables, combine with IP Forwarding feature of Linux, can be configured for creating static nat.  This post will give example configuration to have static nat in Linux machine.

By creating interface configuration, ip address, and gateway configuration will remain when machine reboot.  In Debian, this configuration can be writen in configuration file name "interfaces" in directory "/etc/network/".  The configuration file will have like this:

Iptables provides packet filtering, network address translation (NAT) and other packet mangling.

Two of the most common uses of iptables is to provide firewall support and NAT.

Configuring iptables manually is challenging for the uninitiated. Fortunately, there are many configuration tools (wizards) available to assist: e.g., fwbuilder, bastille, ferm.

This procedure is used for recover switch 2900, 3500, and 3750 series.
1. Connect to switch with console
2. Unplug power cable
3. Hold down mode button when reconnect the power cable to bring to switch: mode

Sometimes you lost your router password, or you work as network administrator in new places, that no one knows the password of your new company router. Here the procedure for recover the password.

Configuring nat and without nat is pretty simple. It's just configuring nat and global configuration. Nat id correspond with with same global id. For example, you want all traffic from inside interface will be been nat to outside interface ip address when going to internet through outside interface, then you need configure this.

This post will show example of configuring firewall filter to protect routing engine in Juniper.  In Junos, to protect router itself (local routing engine) against attack, like DDoS attack, and TCP Sync attack, or unauthorized access, can be created using firewall filter then apply filter in loopback interface. This post will describe examples for protecting local routing engine against unauthorized access, also icmp, and tcp floods.

By creating new folder, and rename it to GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}, you have all you need for configuring your Windows 7.

If you have familiar with Linux or Unix, you must know about change ownership or chown. Windows 7 has such a concept like that. Like on Linux or Unix, if you are an administrator, you can change or take ownership of file and folder. To do that, here are the way:
