I am running Kali Linux (installed on ssd) on an old Fujitsu PC, spec
wise its an old 8 core i7, 20gb of memory and a 240gb ssd and a 250gb
spinney hard disks. Kali is all update
The reason for running Kali is that I am trying to hack my own router (
I mentioned a few months ago I had lost the password). I thought it
would be an interesting fun project to learn a bit of hacking skills, it
it gets to a point where I need to get onto the router then I will
simply stop and reset the router.
Anyway I have produced some 6 digit wordlists, they are approximately
329mb in size and contain around 49,000,000 words, the maximum Hydra the
program I am using can handle is 50,000,000. Now the PC is running 24/7
trying to crack the password. It takes around 24 to 28 hours to complete
a single wordlist, but what I am finding is that when the PC approaches
running for 2.5 days the processing of attempts slows right down from
something like 28000 to as low a 4000 an hour and then take 4 days to
complete.
Now memory does not seems to be a problem (see below) nor does SSD free
space 185GB in my Home partition, using ext4 format, there no high cpu,
it bumbles around 8% per processor. PC is connected to 1gbit switch (HP
1910) which is in turn connected to the router.
mit@NX1:~$ free

Swap: 10238972 768 10238204
There no noticable difference when using the router when the scans are
running at full throttle or low throttle. Rebooting the PC resolve the
slow down issue but after couple of days it is back.
Anybody any idea why I am getting the slowdown
