Faking the Uptime in Linux

Submitted by on May 4, 2015 – 10:05 pm

If, for whatever reason, you need to fake the Linux server uptime, there is a hacked kernel module you can use. The instructions are below.

cd /tmp ; wget ; unzip ; cd uptime_hack-master ; make; insmod uptime_hack.ko uptime=0; echo 1020210 > /sys/module/uptime_hack/parameters/uptime ; echo y > /sys/module/uptime_hack/parameters/hideme ; uptime

Replace the “1020210” string with a number where 1 is approximately 1001 seconds, thus 1020210 means uptime of about 11830 days.
