记折腾电信4K IPTV盒子的周末给自己带来的新知识

 

上个月家里宽带升级了200M, 顺带看到可以免费享受一路4K的IPTV.

其实一直都知道电信的宽带可以免费申请IPTV, 但是一直都没弄, 主要原因是一直都没找到合适的办法去只用一根网线来解决我上网出口跟IPTV的问题..曾经看到一些方案但是都觉得不合适或者说不够理想, 而在几周前,在Chiphell毒坛看到了一个近乎完美的解决方案https://www.chiphell.com/thread-1421026-1-1.html, 这样一来4K的IPTV自然就可以顺理成章的入住了.

ASUS梅林固件配置IPv6

 It took me a bit to get this going so i thought i would share. When you are done you will have IPv6 in your home for all your devices.

High level instructions
1. sign up for a (free!) tunnel account @ http://tunnelbroker.net/
2. change your DDNS settings in asuswrt to reset your v4 IP if it changes
3. Setup a ipv6 6in4 tunnel
4. put an ip6tables firewall script on
5. run the test @ http://test-ipv6.com/ and enjoy!

OK, some details.
I assume you can all do #1 without trouble.

For #2, On your asuswrt interface, go to WAN/DDNS. Select the 'www.tunnelbroker.net' provider. In the 'Host Name' put the tunnel ID your tunnel has. This is a ~5 digit number, and appears on your 'Tunnel Details' page on the tunnelbroker.net website after you have logged in. In the "User Name or Email Address" put your user-id which is a really long alphanumeric string for User ID that you will see if you click on "Main Page" (just above account info) on the tunnelbroker.net site. Then enter your password. Once this is done, the DDNS client on the router will update HE each time your IP changes.

For #3, select 'IPV6' on the asuswrt interface. Select 'Tunnel 6in4' for connection type. Enter the Server IPv4 Address from your HE tunnel details page. Enter the Client IPv6 address (without the mask... this should end in ::2). Select 64 for ipv6 prefix len. Select 1480 for Tunnel MTU. Select 255 for Tunnel TTL. In the IPv6 lan settings, take the value from the 'Routed /64' on your tunnel details page, and enter it as LAN ipv6 prefix. Do not put the mask, but end in :: (e.g. X:X:X:X:. Enter 64 for the prefix len. In the IPv6 DNS resolvers, put 2001:470:20::2, 2001:4860:4860::8888, and 2001:4860:4860::8844. Now select 'Enable Router Advertisement'.

@ this stage you should have ipv6 connectivity, you can check that here: http://test-ipv6.com/, or run 'ifconfig' on your linux machine, or ipconfig on your windows machine. These should have gotten an ipv6 from the router via router advertisement. If not, debug until you do.

For #4, you are going to want to do some firewalling I think (If you are happy with all your interior machines open on the internet, skip). Go to the administration/System tab, enable JFFS. Now create a file called /jffs/scripts/firewall-start [i did this via SSH] based on the attachment to this thread. You need to change the top 3 lines to match your tunnel IP interfaces.

This will allow any machine inside your house to do what it wants, but disallows incoming connectivity.

At this stage, re-run the ipv6 test http://test-ipv6.com/, and you should be good to go.

You may wish to remove the bottom 3 lines of the script (the LOG) ones, they are for debugging, but cost a lot of perf.

The "debug menu" (also called the "maintenance mode") on a Garmin Nuvi 750 is a utility that allows you to reset your device back to factory settings. 
You can reset any addresses saved to the device as well as custom points of interest, such as restaurants, hotels or whatever. 
You don't need to do anything special to enter this menu on the device, you simply just need to press in the right location at the right time.

Steps to Enter Debug Menu

1.Turn off your Garmin Nuvi 750.
2.Press and hold your finger in the lower, right-hand corner of the Nuvi 750's touchscreen.
3.Turn on your Nuvi 750 while continuing to press on the unit's screen. This will launch the debug menu on the device.
4.Press "Yes" or "No" when asked if you want to restore your device factory settings. You can also press the other button on-screen to continue into "maintenance" or "debug" mode.

Exit the Debug Menu
To exit out this special menu on your Garmin Nuvi 750, simply turn the device off and turn it back on again.

Netgear A6210 802.11ac无线抓包网卡安装使用说明

 功能需求

在处理无线网络问题时,一般会有一个初步排查的过程,判断具体出问题的节点。由于无线网络是电磁波,传输介质是在空气,没有实际存在的物理链路。经过初步排查后,如果怀疑问题出在AP到无线终端这一端,常常无法判断具体问题是出在无线客户端上还是在AP上。此时就需要采集到报文在空间传输过程中的交互,再定位具体问题出在哪个节点。

TTL和RS232之间的详细对比

之前就听过TTL,一直没搞懂其和RS232的区别。

最近,打算去买个USB转RS232的芯片,结果找到此产品:
