Buried Treasure. What a great name for a book. Oh, yes. The mystery, the intrigue Who among us wouldn't rather unearth a hidden treasure than win a lottery? Marry rich? Well, okay then--forget that last example. I've read Allan's previous novels and love her writi. When the bough breaks This is Luke's third guest appearance on my blog.

Yep, I think he has a crime series going here Who partied in the woods? As per yesterday's blog, I could tell from prints I found in the snow that the bears had awoken from hibernation One footprint in the snow. A footprint in the snow on my walk this morning, set my head abuzz. There was a story in that single print, a reminder to be concise in my own writing, to show not tell.

To weave the past into the future. To build suspense.


Yes, all of that from just one print. The lone bear print I found in the snow It was a fresh a print. I could tell because this was Monday and on Saturday we had received a lot of rain, which would have wiped out the print, or at the very least smudged the ed. Keto Krumbs -- My Advice. When I posted my keto diet comment on Facebook bemoaning the fact I was not losing weight , I was looking more for sympathy than advice. But I got lots of advice and sympathy, too. I didn't need advice as I'm under the care of both a registered dietitian and my family doctor.

Obviously, I'm not the only one battling a weight problem. I recently acquired what I fondly refer to as my "snoring machine".

It took me a couple of weeks to get used to the trial machine, despite the fact. Harvest Poetry. Bright spell.

Dusty, musty new-mown smellsof harvest. I feel. Mushrooms and Roses. I felt somewhat like young Katrina, the protagonist in The Traz, out there today in the mellow autumn sun with my basket.

See a Problem?

However, Katrina accomplished a lot more with her mushroom picking, than I did. Female Writer, Male Protagonist Although I have male characters in all my published novels, the main character has always been female. I'll break with that tradition in my upcoming SciFi trilogy, Project W. Olf to be released by WolfSinger Publications in I remember writing a short story in Grade 6 and my teacher complimenting me on writing first person from a male perspective.

She said children usually stick to writing from their own gender view point. So immersed had I been in my story, until the teacher. Three Things I didn't know until today. It seems one mindlessly accepts the world as it is until something, for reasons not understood, piques one's interest. Eileen Schuh, Canadian writer www.

Chetan Soni - Sr. Security Specialist, Secugenius Security Solutions. What is Advanced Policy Firewall? Advanced Policy Firewall APF is an iptables netfilter based firewall system designed around the essential needs of todays Linux servers. The configuration is designed to be very informative and easy to follow. The management on a day-to-day basis is conducted from the command line with the apf command, which includes detailed usage information on all the features. APF is developed and maintained by R-fx Networks.

The technical side of APF is such that it utilizes the latest stable features from the iptables netfilter project to provide a very robust and powerful firewall. The filtering performed by APF is three fold: 1 Static rule based policies not to be confused with a static firewall 2 Connection based stateful policies 3 Sanity based policies.

North-south firewalls control mutual access between tenant network users and external networks. Understanding these concepts helps you better understand service traffic forwarding of the solution. Tenant virtual router tenant vRouter is a dedicated VRF on a gateway node created for a tenant. A tenant vRouter connects tenant vFWs and PEs and applies to the scenario where firewalls are deployed in bypass mode. The virtual systems of firewalls are classified into two types: Public virtual firewall public vFW : is a special virtual system that exists on firewalls by default.

After the virtualization function is enabled, the public vFW inherits the previous configurations on the firewalls. Virtual system VSYS : is a logical device divided on a firewall. Each VSYS works independently. I n a large Layer 2 data center network, there are many physical and virtual machines. A large number of ARP broadcast packets will pose huge pressure on gateways and tenants.

Gateways may be affected greatly because they need to learn and manage ARP entries. In addition, a massive number of ARP packets will occupy high bandwidth.

The following figure shows the implementation of ARP broadcast suppression. When the leaf switches receive local ARP requests, they convert broadcast packets into unicast packets based on host information before forwarding packets. I n dual-firewall hot standby, two firewalls are deployed. The active firewall forwards services, and the standby firewall monitors the forwarding. The active firewall periodically sends status and backup information to the standby firewall. When the active firewall is faulty, the standby firewall immediately takes over services on the active firewall.

  • Dual-firewall hot standby is characterized by a dedicated backup tunnel heartbeat line. The service interfaces of the two firewalls use the same IP address. Therefore, they can be considered as one firewall. After dual-firewall hot standby is enabled, most configuration commands only need to be executed on one firewall, and will be automatically synchronized to the other firewall. VPN encrypts data packets and converts destination addresses at both ends data egress to transmit data in enterprise interconnection.


    You can configure IPSec VPN to enable communication between the enterprise data center and enterprise private network. T he FabricInsight is a data center network-based big data analysis platform developed by Huawei. It can collect and analyze application and flow information on data center networks and display the information to users, helping users monitor the health status of networks and applications and quickly demarcate and rectify faults.

    The FabricInsight provides the following functions:. Network insight Collects statistics about network parameters, such as the number of SYN events, traffic volume, average delay, and maximum delay, in real time. Clearly displays the status of network devices and links. Application insight Uses the application map to clearly display the interaction relationship and quality of applications, and collects statistics on key parameters, such as the number of applications, number of hosts, average inter-application delay, and average intra-application delay.

    Flow insight Enables users to view flow event details, including the quintuple information, status normal or abnormal , delay, traffic volume, all flow events such as link establishment and disconnection events of the current flow in a specified period, and topology paths used in specific events. It has the following functions:. Visualizes attack paths to show the attack process and path.

    Supports security posture awareness to predict attack trends. M icrosegmentation, also called EPG-based security isolation, groups servers on a data center network based on rules. It provides identity authentication, data encryption, integrity check, and anti-replay to protect Ethernet frames and prevent attack packets.
