can you fake *nix uptime?
提问by c2h2
Just curious, Can you fake an uptime, for instance increase it to 10 years?
只是好奇，你能伪造一个uptime，例如将它增加到 10 年吗？
I have tried changing system time, and it won't do this trick.
我试过改变系统时间，但它不会做这个把戏。

alias uptime='echo " 11:07:17 up 10 BILLION YEARS!, 4 users, load average: 0.38, 0.52, 0.41"'
If you want to get extra-fancy, you could take the actual uptime output and modify that.
如果你想变得更花哨，你可以获取实际的正常运行时间输出并修改它。

Yeah, you should be able to attach a gdb to the running kernel, and hack the uptime value. You'd need to know where it was kept, and have a symbols file. I am assuming here, that uptime is held in something statically allocated.
是的，您应该能够将 gdb 附加到正在运行的内核，并破解正常运行时间值。您需要知道它的保存位置，并有一个符号文件。我在这里假设，正常运行时间是静态分配的。
Alternatively, write a small kernel module which hacks the uptime when you load it (and immediately unloads again).
或者，编写一个小的内核模块，它会在您加载（并立即再次卸载）时缩短正常运行时间。
