php5 3 years old and php4 7 years old

php 5.2.3 release!


"The PHP development team would like to announce the immediate availability of PHP 5.2.3. This release continues to improve the security and the stability of the 5.X branch as well as addressing two regressions introduced by the previous 5.2 releases. These regressions relate to the timeout handling over non-blocking SSL connections and the lack of HTTP_RAW_POST_DATA in certain conditions. All users are encouraged to upgrade to this release."

I’ll do upgrade for my box but my hosting service still use 5.1.2 ( from phpinfo() ).

While php4 already  reach 7 years of deployment make this version still in my favourite ( I install php4 as apache module and php5 as cgi)

for windows user xampp or wamp provide the latest version of php for complete. Switch to php4 and php5 very easy as switch menu available.

with slow migration php4 to php5 then php6 become more difficult to adopt since it force user to make secure programming with superglobals and register_globals Off.

Life is option so with the php version 🙂

Oh no, fedora 7 is out too, no ‘core’ , just plain fedora in the name.

time for wget 😉

Lab topology for your ccna, ccnp, ccie certification or just playing around

While surf on internet I found a lot of topology ready to test and explore, more come from hacki forum. I just remember Solarflux collecting various pf.conf sample for learning purpose. Same purpose I try to do with this post before take my Cisco Certified Network Associate (CCNA) 640 802. Like 101 resources for self learning cisco, I’ll update this list regularly once I found new topology.

List of books that might useful in understanding the topology :

15. MPLS VPNs with duplicate customer addressing

Here’s a topology file I’ve created with a 4-node MPLS network. Two MPLS VPNs are configured with identical LAN and WAN addressing. The 4 PE routers exchange routes using MP-BGP and use OSPF for the full mesh of MPLS connections. Each CE router has two connections to the network. I’ve included a PDF file that lays out the topology, IGP and VPN routing. ( Justin White CCIE #14745)

It consists of a Hub and a Spoke router emulated on the Dynamips emulator

18. MPLS VPNs v1.5 with MPLS-TE instead of LDP

Here’s the version 1.5 of my MPLS lab updated to use MPLS-TE instead of LDP for distribution of labels. There aren’t any other changes over version 1, so the diagrams should be identical. Remember that this version consists of a 4-node MPLS network. Two MPLS VPNs are configured with identical LAN and WAN addressing. The 4 PE routers exchange routes using MP-BGP and use OSPF for the full mesh of MPLS connections. Each CE router has two connections to the network ( Justin White CCIE #14745 )

19. MPLS VPNs v2.5 with MPLS-TE instead of LDP

Here’s the version 2.5 of my MPLS lab updated to use MPLS-TE instead of LDP for distribution of labels. There aren’t any other changes over version 2, so the diagrams should be identical. Remember that this version consists of a 6-node MPLS network with a pair of P-core routers that also act as route-reflectors for the PE routers. ( Justin White CCIE #14745 )

22. ccie practice lab dynamips

.net topology that is smaller but very useful for IP Services practice like Proxy Arp, NAT, HSRP and all the things you want to test that do not require a full lab of 13 routers.

the lab was prepared from the IEWBv4 IPServices book under Advanced Technologies also to people that do not have this Work Book it can be very handy as it is not very hard to figure the structure of the lab.

26. Sample topology for Inter-AS MPLS VPNs

After reading a section from “MPLS and VPN Architectures, Vol 2”, I looked closer at a feature that allows VPNv4 routes to be exchanged between two MPLS networks without requiring LDP or MPLS-TE, just BGP. Here’s the Cisco document:

MPLS VPN—Interautonomous System Support

Only the sample in the Cisco docs doesn’t document every step involved, so I’ve used their topology and filled in my own blanks. The attached ZIP file has a PDF showing the topology. Table 3 shows the specific platforms and minimum versions of IOS that support this feature.

Personally, this might be one of the coolest features that might appear on the CCIE SP lab. This was really fun to put together and I hope it helps someone one else too.

27. IPV6 RIPng

28. BGP/Default Route Lab (Brian)

Here’s a topology that mimics a network I just completed building. It consists of one location (AS65000) multihomed to 2 ISP’s (AS300,400), with a remote site (R2) connected to ISP B (AS400). Both sites, (R1,R2) are connected with a T1.

What I’m doing with this lab is sending a default route to R2 via BGP, full tables to R65000, and redistributing the default path to OSPF.

Since I’m using IOS firewall images, you could also have IPSec/GRE tunnels setup and run OSPF between R1 and R2.

29. IPv6 EIGRP Topology

Here is an IPv6 EIGRP Topology over Frame-Relay with an OSPFv3 route redistributed in to EIGRP.

Frame-Relay Cloud
R1 – IP Address ABCD::AC0C:7B01/96 (s1/0)
R2 – IP Address ABCD::AC0C:7B02/96 (s1/0)
R3 – IP Address ABCD::AC0C:7B03/96 (s1/0)

Fast Ethernet
R2 – IP Address BCDE::AC0C:1702/96 (fa1/0)
R3 – IP Address BCDE::AC0C:1703/96 (fa1/0)
R4 – IP Address BCDE::AC0C:1704/96 (fa1/0)

Point-to-Point Serial
R3 – IP Address CDEF::A02:203/96 (s1/1)
R4 – IP Address CDEF::A02:204/96 (s1/1)

R1 – IP Address 1111:1111::/16 (Lo0)
R2 – IP Address 2222:2222::/16 (Lo0)
R3 – IP Address 3333:3333::/16 (Lo0)
R4 – IP Address 4444:4444::/16 (Lo0)
R4 – IP Address 4545:4545::/16 (Lo1)

To use a Full Mesh Frame-Relay you have to map the link-local and interface addresses to the dlci. Only the link-local will have to be broadcast. Link-local addresses may vary from mine.
The command is frame-relay map ipv6 <IP Address> <DLCI>

Do a show ipv6 interface f0/0 to get the Link-Local address for each router connected to the frame-relay cloud.

To enable IPv6 routing type ipv6 unicast-routing followed by ipv6 cef globally

Then type ipv6 router eigrp <process> followed by no shutdown.

The EIGRP process by default, is in a shutdown status. Just like an interface. You will have to type no shutdown in the EIGRP process. This is a common error for those new to IPv6 EIGRP.

EIGRP also has to be enabled at the interface level by typing ipv6 enable followed by ipv6 eigrp <process>

Put R4’s Loopback 1 into OSPFv3 area 0, then redistribute it into IPv6 EIGRP.

Ping all Address.

If you want to duplicate this topology you need at least IOS Version 12.4(6)T. Thats when Cisco introduced EIGRP for IPv6.

30. IPv6 running OSPFv3 & RIPng

Here is an IPv6 Routing Lab – Using 4-3640 Routers

It is running OSPFv3 and RIPng. Redistribution will be set up on R3. This will be a pure IPv6 environment. (as pure as I can get it)

I recommend IOS 12.3 or better

R1 & R2 are connected via Serial links using these ipv6 addresses
R1 — 0:1111:2222:3333::1/48 (s0/0)
R2 — 0:1111:2222:3333::2/48 (s0/0)

R2 & R3 are connected via Serial links using these ipv6 addresses
R2 — 0:2323:2222:3333::2/48 (s0/1)
R3 — 0:2323:2222:3333::3/48 (s0/0)

R3 & R4 are connected via Ethernet links using these ipv6 addresses
R3 — 0:3434:3333:4444::4/48 (e1/0)
R4 — 0:3434:3333:4444::3/48 (e1/0)

The Loopbacks for each router
R1 — 0:1111:1111:1111::1/48
R2 — 0:2222:2222:2222::2/48
R3 — 0:3333:3333:3333::3/48
R4 — 0:4444:4444:4444::4/48

The first thing you should do is enable ipv6 unicast-routing and ipv6 cef globally.

Then enter the IPv6 addresses.
Note: some IOS require you to type ipv6 enable at the interface level.

Router 1
Enable a router-id of for the OSPFv3 process
The Loopback and the Serial interface should be in area 0
Turn off ipv4 routing

Router 2
Enable a router-id of for the OSPFv3 process
The Loopback and both Serial interfaces should be in OSPFv3 area 0
Turn off ipv4 routing

Router 3
Enable a router-id of for the OSPFv3 process
The Loopback interface should be in OSPFv3 area 3
The Serial interface should be in OSPFv3 area 0
The Ethernet interface should be in RIPng process
Turn off ipv4 routing

Router 4
The Loopback and Ethernet interface should be in the RIPng process
Turn off ipv4 routing

Redistribution on Router 3
1.) Redistribute RIPng routes into OSPFv3 with a metric of 120 and include connected routes.
2.) Redistribute OSPFv3 routes into RIPng with a metric of 3 and include connected routes.

Make sure you can ping all routes.

Some Basic IPv6 commands
ping 0:6754:4567:8899:33:84:4
show ipv6 route
show ipv6 rip
show ipv6 ospf
show ipv6 interface brief

Cisco Lab for Free

amazing, I never imagine if Cisco lab can accessed online. Just signup, make reservation and do real thing you want in real lab. While you’re in China you can access Cisco lab in USA 🙂

I found two labs that might be useful for you :

1. Firewall CX

From their site :

The Cisco lab is a project that started in November 2004. Its purpose, to create the world’s first free, fully equipped Cisco lab and help the community learn and gain hands-on experience with Cisco equipment.

The investment made on this project is remarkable and next to none. Over $US10,000 has been spent on the lab equipment and various peripherals, aiming to provide the best possible simulations a lab can give. Hundreds of hours in research and development have been put in by our Team and other developers in order to enhance the labs and deliver an outstanding quality of service not found even on rented Cisco labs currently on the market.

Our lab is based on real Cisco equipment complemented by services such as ISDN simulators providing real ISDN calls between our routers, TFTP servers to allow you to save and restore your configurations and many more.

Each lab is split into two or more tutorials to gradually increase the experience and knowledge gained. The tutorials are carefully designed to focus on important details that might be required in the real world, while at the same time covering sections of Cisco’s CCNA and CCNP certifications.

The equipment comprising our labs make it possible to cover up to the CCNP level of Cisco certifications.

The flexibility offered by our labs is equally impressive; you are not confined in any way, and are allowed to freely modify all equipment you have access to. This gives you the ability to create and test your own setups, to help you troubleshoot problems or test new designs which can then be applied in your real working environment

Provide Cisco lab equipment has been installed in a 26U – 19′ inch rack, complemented by blue neon lighting and a 420VA UP to keep everything running smoothly, should a blackout occur.

Firewall CX have three labs :

  • The lab’s Catalyst 1912 supporting two cascaded 1603R routers, and a 501 PIX Firewall.
  • The lab’s two 1603R routers
  • Three high-end Cisco switches flooded in blue lighting, making VLAN services a reality. Also optical links connecting the three switches together, permitting complex STP scenarios.

Make sure check lab 1 tutorial

2. FreeCiscoLab

The lab is powered by a cisco access server which gives full access to the console port of each device in the lab. When your registered timeslot becomes avaiable, you telnet into the access server on port 23 using any standard telnet client.

Same as Firewall CX, make reservation first 🙂

3. Free Labs supplies access to live cisco equipment over the internet. Certification Candidates and Network Analysts can study protocol behavior, simulate network problems, or test new deployments.

Why are we doing this for free? – Because we know how difficult it can be to afford access to real Cisco equipment while working on your certifications. Also, we hope that by offering you this exceptional service, you will become comfortable enough with our company to buy our Expert-Labs timeslots, when the time comes for more serious network analysis or deeper CCIE-level study.

Overview – Pod #1

The Pod 1 Lab Topology includes 7 routers, 1 switch, 9 serial links and 7 Ethernet links. The star topology hubbed on router 7 is ideal for Frame Relay or any NBMA type protocol simulation. All devices are equipped with the most feature-rich software available, allowing simulations of virtually all routing protocols, and even IPv6.

Overview – Pod #3

Pod #3’s Topology is slightly different, with 2 less routers. Use the Frame Relay Mesh to learn your Routing Protocols inside out!

After learning how to configure the lab, I suggest that you increase your knowledge in security and experience by receiving a cissp certification or by attending a computer forensics boot camp course.

I’ll update this list, soon as I find other lab.

Free, secure and smart dns with OpenDNS

Recent surf activity sent me to interesting website, OpenDNS

What is OpenDNS?

OpenDNS helps you navigate the Internet in a safer, faster, smarter and more reliable way. Our service is free and requires nothing to download. OpenDNS doesn’t replace your existing Internet connection, it just makes it better.

Important useful things for me (taken from their FAQ) :

Why is OpenDNS safer than what I’m using now for DNS?

OpenDNS intercepts phishing attempts. OpenDNS customers will be warned if they attempt to visit a phishing site.

Why is OpenDNS faster than other DNS services?

Two things make OpenDNS faster than similar services. First, OpenDNS runs a really big, smart cache, so every OpenDNS user benefits from the activities of the broader OpenDNS user base. Second, OpenDNS runs a high-performance network which is geographically distributed (see network map) and serviced by several redundant connections. OpenDNS responds to your query from the nearest location. That means we’re very fast (and extremely reliable, to boot).
