Linux Default route remove and add

說明:
  由於筆者管理中的某台機器裝上雙網卡後怪怪的, 第一個網卡對外掛掉後不會切到第二張網卡, 因此筆者簡單筆記怎麼重設default route
顯示系統的routing table
shiun@test:~$ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.0.253 0.0.0.0 UG 0 0 0 eth0 192.168.0.0 * 255.255.255.0 U 0 0 0 eth0 192.168.1.0 * 255.255.255.0 U 0 0 0 eth1

將第二張網卡(eth1)改為default
# 刪除對應到eth0的default shiun@test:~$ sudo route del default # 將192.168.1.1(eth1)改為新的default shiun@test:~$ sudo add default gw 192.168.1.1
這樣就ＯＫ了

樹莓派 Raspberry Pi2 John the ripper (開膛手約翰XD?)

應觀眾要求測試Pi2跑John的效能, 結果如下列資料所示

由於筆者對john沒有研究, 分析的工作只好無限延期XDDDD
