review
base on gre_keepalive_06.c
繼續前進
gre_keepalive_07.c
已經能搭配 libpcap 抓取到 gre tunnel keepalive response
讓程式可以吃參數吧
把需要的參數列出來
- device
- tunnel device
- local address
- remote address
- period
- <0-32767> Keepalive period (default 10 seconds)
- retries
- <1-255> Keepalive retries (default 3 times)
寫得差不多了
還差 keepalive retries 機制
還有去控制 tunnel device 的 up/down 狀態
gre_keepalive_08.c
已經達到目前我想要的樣子
可以開始設計 icos 的模組了
繼續前進之前先上 code 吧
m330[release/v0.08] - implement grek - GRE Tunnel Keepalive

找一台其他家的來對測一下
直接去隔壁搬一台 cisco 來做測試
幫 jessy 加一下 web ui
build 一份 m330[release/v0.08] 最新的 code
- Vendor/Products = GENERIC/1_GENERIC_WIFI
m330[release/v0.08] - add 'Country Code' field at 'WAN > WiFi STA' web page

從 shin 那邊借了一台 cisco 2800
網路線插上標示著 FE 0/0
的接頭
Router>show interface
FastEthernet0/0 is up, line protocol is up

...
FastEthernet0/1 is up, line protocol is down
...
利用 show interface 會發現 FastEthernet0/0 is up, line protocol is up
先把該 interface 的 ip 改成適合我環境需要的

可以來建 gre tunnel 了
連最基本的 gre tunnel 都建不起來...
明天繼續
