One Peanut Bar and Black Group
This article can be seen as the "Blood Case" triggered by Fiji's K2 brushing old Maozi firmware. According to the usual first drying out of the box diagram:

Let's introduce what a peanut bar is. (The old driver shouldn't bother.)
Peanut stick is a piece of hardware that comes with peanut shell software, can be seen as a small host, what use? It is convenient for you to access devices in the intranet environment, such as a company or home, and to remotely control or connect intranets when you are on a foreign network.
Do not look at this concept is very simple, Peanut Shell official website and BBS did not say clearly. . . (Or disdain to talk about it). Many newcomers (including myself) saw the official website forum discussions in full swing, often confused.
Why should I buy it? After the Fiji K2 got on the vehicle for advertising filter function and scientific Internet access, the firmware of Lao Maozi was used. It was so cool that it was impossible to control the router remotely. Look at the "millet wifi" APP on the mobile phone, and don't toss me. Think of peanut bars
This is the goods
Peanut Bar - Oray Mall Oray Online Mall Peanuts 2 is a hardware that implements the intranet penetration dynamic domain name resolution technology. The peanut shell service will be opened to the peanut stick built-in account, with the peanut shell (intranet version) service use. Direct link to store.oray.com Every Tuesday at 11 am, 98 yuan snapped up
First, set a simple
1. The peanut bar is connected to the mobile phone charger and then connected to the router that can automatically allocate the intranet IP
2, landing Peanut shell official website, select peanuts SN landing (is out of the box in the coding area), and then set the intranet mapping
3, landing outside the network access address can be connected to the intranet
Second, compared with the PC running peanut shell, saving electricity, compared with the router + peanut shell, peace of mind
Old Peanut shell PC client no longer has to open the computer, the electricity fee saves a lot
If you have a router or peanut shell, think about the troubles of various operators' intranet environments.
First, the flow is not enough
Peanut sticks are free accounts, the only difference is 2G traffic per month.
I tried to backup the mobile phone photos through peanut bar + black group Hui, as shown above, 100M gone, save it
Second, port mapping is not enough
Traffic tricks do not say, the port mapping can only set two ... I used to access the DSM, one used to access the PhotoStation, it is used up. . . Say a good remote control router
Go out and turn left and go black Let's take a look at the old computer at home, using the notebook
Lenovo Y550A
Listed in 2009, T6400 Core Duo 2.0GHZ
How to brush machine is not introduced, the Internet catch a lot, simple and fast
Let me talk about the needs of my group
1, Thunder remote download
2. Remotely backup mobile photos via WIFI (weapons when traveling)
3, home media center
In fact, the first and second Thunderbolt download treasure will be able to achieve, but also cheap, stable, the key is no flow restrictions (but limit the remote download intranet hard disk video)
In fact, think about the Thunder has to make money Baobao Yao, Thunderbird can provide free bandwidth, this point back up the mobile phone photos, sprinkle sprinkler friends
The key is the third point, and Qunhui impressed me.
It is said that the group sells the service, and the machine is a bonus. At the beginning, I couldn't understand until I heard that there is a notestation (equivalent to the private cloud version of Evernote or Cloud Notes, for me who is used to collecting subscriptions). Words, really pain points. However, the notestation collection subscription number article has not been able to capture the picture... is still honest and practical to know notes) and the photostation (website photo wall is too like), as shown below
Waterfall flow waterfall flow
Go Out Right Experience Falls Flow Heckles.cn.quickconnect.to Direct Links In addition, the iOS and Android versions of DS PHOTO (official APP) are all extremely smooth on the intranet.
The goddess in the hard disk can see the sky again
to sum upIn fact, electronic products, this thing, some people burn equipment, some people love toss, "burn yourself", I have no money to burn equipment, you can only toss.
Originally peanut bars bought back to want to penetrate the network + remote control, but unfortunately two ports + 2G monthly traffic restrictions, but also pushed me to the black group Hui whitewash the road.
Come to buy advice
First, peanut bars if used to penetrate the internal network backup data, quite tasteless (the same flow with my mobile phone package ...), bought just to control the network equipment and not worthwhile (download mainstream Thunder, Thunder remote or Download treasure comes with the function of penetrating the internal network, other features may not as good as buying a WiFi socket practical)
Second, the Group's service is good, if there is important information you need to back up frequently synchronized, it is recommended on the white skirt (white wash does not know when the official will rise to the block). If you just want to be a home media center, you can use old equipment to experience it.
Write so much first, plan next dual-gigabit routers, and own a USB3.0 + Gigabit LAN + SATA3.0 NAS as a home media center, peanuts right after the black skirt to prevent whitewash An insurance policy
PS: I am soft whitewashing, some soft wash tutorials on the Internet have omitted the steps to generate SN that can be verified, do not know if the official verification becomes stricter (how to generate your own mother)
Product Description
SPD Surge Protective Device,Lightning Surge Protector
Surge Protection Device (SPD)
It is a device used to limiting instant surge voltage and discharge surge current, it at least including a non-linear component.
Surge protective Device Model Selection
With the impact of international information flow, the rapid development of microelectronic science and technology, communication, computer and automatic control technology, make the building start to go for high quality, high functional area, formed a new building style-intelligent building. As inside the intelligent building there are lot of information system, <<Building lightning protection design norm>> GB50057-94(2002 vision)(hereafter brief as <<lightning protection norm>>) put forward the relative requirement to install the surge protective device, to ensure the information system safely and stable running.
SPD essentially is a equipotential connection material, its model selection is according to the different lightning protection area, different lightning electromagnetic pulse critical and different equipotential connection position, decide which kind of SPD used in the area, to achieve the equipotential connection with the common earth electrode. Our statement will based on SPD's maximum discharge current Imax, continuous operating voltage Uc, protection voltage Up, alarm mode etc.
As per << Lightning Protection Norm>> item 6.4.4 stipulation "SPD must can withstand the expected lightning current flow and should confirm to the additional two requirements: the maximum clamp voltage during surge across, capable to extinguish the power frequency follow-on current after lightning current across." That is the value of SPD's max. clamp voltage add its induction voltage of two ends should be same with the system's basic insulation level and the equipment allowed max. surge voltage.
SPD for Power Supply System Series Selection Guide
The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity.
The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose.
SPD for power supply system specification selection principle
Max. continuous operating voltage: bigger than protected equipment, the system's max. continuous operating voltage.
TT System: Uc≥1.55Uo (Uo is low voltage system to null line voltage)
TN System: Uc≥1.15Uo
IT System: Uc≥1.15Uo(Uo is low voltage system to line voltage)
Voltage Protection Level: less than the insulation withstand impulse voltage of protected equipment
Rated discharge current: determined as per to the lightning situation of the position installed and lightning protection zone.
