ffcfstress(1) General Commands Manual ffcfstress(1)NAME
ffcfstress - constant force stress test for force-feedback devices
SYNOPSIS
ffcfstress [-d <device>] [-u <update rate>] [-f <frequency>] [-a <amplitude>] [-s <strength>] [-x <axis>] [-A] [-o]
DESCRIPTION
ffcfstress stress tests constant non-enveloped forces on a force feedback device. It simulates a moving spring force by applying a fre-
quently updated constant force effect.
Beware, the stress test may damage your device!
OPTIONS
At least one option is required.
-d <device>
The device to test (by default /dev/input/event0).
-u <update rate>
The update rate in Hz (25 by default).
-f <frequency>
The spring center motion frequency in Hz (0.1 by default).
-a <amplitude>
The spring center motion amplitude, between 0.0 and 1.0 (1.0 by default).
-s <strength>
The spring strength factor (1.0 by default).
-x <axis>
absolute axis to test (default: 0)
[0 = X, 1 = Y, 2 = Z, 3 = RX, 4 = RY, 5 = RZ, 6 = WHEEL]
-A switch off auto-centering
-o Dummy option, useful when all defaults should be used.

gr_plot_fft_c - plot complex binary data using GNU Radio
SYNOPSIS
gr_plot_fft_c: [options] input_filename
DESCRIPTION
Takes a GNU Radio complex binary file and displays the I&Q data versus time as well as the frequency domain (FFT) plot. The y-axis values
are plotted assuming volts as the amplitude of the I&Q streams and converted into dBm in the frequency domain (the 1/N power adjustment out
of the FFT is performed internally). The script plots a certain block of data at a time, specified on the command line as -B or --block.
This value defaults to 1000. The start position in the file can be set by specifying -s or --start and defaults to 0 (the start of the
file). By default, the system assumes a sample rate of 1, so in time, each sample is plotted versus the sample number. To set a true time
and frequency axis, set the sample rate (-R or --sample-rate) to the sample rate used when capturing the samples.
OPTIONS -h, --help
show this help message and exit
-B BLOCK, --block=BLOCK
Specify the block size [default=1000]
-s START, --start=START
Specify where to start in the file [default=0]
-R SAMPLE_RATE, --sample-rate=SAMPLE_RATE
Set the sampler rate of the data [default=1.0]

Hi All,
I was wondering if low strength Ciphers could be avoided on Linux.Following is one kind of solution that I came up with, but not sure if this is correct. Any help would be appreciated!
Solution:
Add the following lines in ssl.conf file:
SSLProtocol all -SSLv2

I'm looking for a script or some other application that will use up a lot of memory on a Solaris or Linux server, in order to test a monitoring application. So far I have found a script that's good for CPU usage but it does nothing for memory. I have also tried the application called 'stress'... (0 Replies)
I have an AIX server running 6.1. My SAN switch is reporting that it is only receiving 5.9 uWatts (micro watts) and it should be well over 100 uWatts. How can I see the transmit strength of my fiber card from within AIX? I have Emulex fiber cards. (1 Reply)
Hi Folks,
Currently we are having the below configuration in one of our AIX 6.1 server.
RAM:- 8 GB
Paging space :- 19 GB
CPU processor:- 1
CPU type: 64 bit
But we would like to upgrade the configuration to below to improve the system performance and resolve some memory issues.

Hi
i want know to how to check NTP update frequency for a server?
what should be its ideal value or range ?
also, i have configure one switch and on gui i can see NTP update frequency value is 1440. also no idea what should be its ideal value
i am not sure if this is correct or not .... (1 Reply)
I want to test the effectiveness of sshguard on some of my systems so I'm trying to write a script that simulates a brute force attack by sending a bunch of different username and password combinations to the servers being tested. So far I have this:

Hi there.
First things first, this is nothing to do with the internet or ISP speed, I know what that is, I know what it's doing.
I have a cluster of 128 single board computers running a branch of Debian. I want to run some kind of stress test to ensure they can transfer data (a) to each... (2 Replies)
