Fedora :: Add / Remove Software - Could Not Do Simulate
Sep 2, 2010
How to get rid of the following error I've been receiving from Yum. I'm fairly new to Fedora. The following message appears when Add/Remove Software is launched. It also pops up periodically in the notification window.
could not do simulate: Traceback (most recent call last):
File "/usr/share/PackageKit/helpers/yum/yumBackend.py", line 3270, in __init__

For backup and pre-functionality purposes, I need to simulate a VirtualHost in my Fedora (14) machine. I found some interesting links to carry out that process but with an IP fix.So, how can I simulate a VH through a localhost with a dynamic IP?

I wrote software which access and reads a serial device. I would like to test this software on my computer without loop-wiring or without a second computer.
How could I use pty's to simulate a serial device?
Actually I would like to temporary replace the /dev/ttyS1 file by one end of the pty. How could I do this? Is there a command to create a pty pair?

Anyone else seeing this? I do 'safely remove' to remove USB flash drive. disappears. Five seconds (or less) later, it reappears. The second time I do 'safely remove', it stays gone.

When I drink tea, the water splashed on my keyboard. It didn't cause any problems until a few mins ago. Now my Enter and right hand side shift key don't function any more (The new line in this text is copied from other thread).
So I would like to know how can I simulate an enter key press so that e.g. a command can be executed in terminal. Because I have some source code uncommitted, I want them at least get committed first.

I'm trying to save the output of the script I wanna run but for some reason I cant manage to do it with "script.sh > Output_4.txt"
The thing is that the script was already run and it extracted some directories so when I try to run it again (to save the log to a Output_4.txt) bash says (see screen-capture) and of course the log's empty!!!!

I have ack-grep installed on my local machine, and find it indispensable for quickly 'acking' through a codebase when debugging. However, on my cheap shared hosting, there is no ack-grep. One of the testimonials on betterthangrep.com mentions a
Rube Goldberg mess of find/grep/xargs which sounds like what I need, but coming from the opposite direction.

I want to simulate a bad block or sector on a drive or even a virtual drive image to test my data recovery distro. I wish I would have bookmarked when I read about it before. It was some type of low level command, I remember something about scsi subsystem or kernel thingabob.

I have a G15v1. After going through hoops and loops to get it working only to discover that you only needed to install g15daemon through the Ubuntu Software Center, I found myself with one big problem. I migrated from windows just now, and there, I had my macro keys(the extra ones) bound to CTRL+W, CTRL+T and to a simulated mouse-wheel scroll so I could navigate the web more easily. How would I go about doing that? I figured, if I used the System->Preferences->Keyboard Shortcuts thingy and bound my key, in my case XF86Launch5, to a command similar to "simulate keypress CTRL+W"(I know it's totally wrong, just to give you an idea), I might be able to get it working again. Only problem is, I can't find anything like that. Any of you has any clue about it? I googled but I only find C++/Java/coding related results, which are not exactly what I need to do.

I need to simulate a 500Mbps link with a 100ms delay and a loss probability of 0.0001% on an ethernet link between two gigabit ethernet cards...I tryed to use these commands:
# tc qdisc add dev lo root handle 1:0 netem delay 100ms loss 0.0001
# tc qdisc add dev lo parent 1:1 handle 10: tbf rate 500Mbit buffer XXXX limit YYYYY
But during some simulation throughputs are very low ( 190Kbps....210Kbps....) for different values of XXXX and YYYY.... (I don't want that the loss probability is caused by the buffer and the limit value but only by the loss probability setted on netem...)

I have a program that receive user input.
I want to run this program automatically without user interaction, and in order to do that I need to simulate key events.
How can I do such a thing?
The program I am running is partly java and partly shell.
The shell part is easily done by using:
./prog.sh <parameters (Parameters being a file containing parameters)
But the java doesn't work similarly.

I have a computer with no floppy drive (x64 ubuntu lucid installed) I have a program (wine windows xp) that will only save data and export data from/to a floppy drive. I found information on setting up an emulated floppy drive. i.e.
sudo dd bs=512 count=2880 if=/dev/zero of=imagefile.img
sudo mkfs.msdos imagefile.img
sudo mount imagefile.img /media/floppy -o loop
I modified the winecfg to include under the drive section A: /media/floppy. Problem is I cannot write to the drive as a normal user. I have tried everything I know but only root can read write to the drive. Is there someway to set up this emulated floppy to allow me as a user to write and read contents.

I have a test RHEL5 box, sitting in a brand new Dell blade rack on a PowerEdge M610, with a lovely Emulex OCm10102-F-M FCoE card connected to a Cisco Nexus 5000 switch. The whole setup is extremely new (the cards only recently became available for purchase.) We've finally worked with Emulex to get the cards functional, and we are ready to some stress testing to the SAN. My question now is, is there a good tool I can use to generate a large amount of traffic to a LUN? The Wintel team used a windows-only tool that showed an average of 6gigs/second throughput, so I need something that can generate very large files and simulate a consistent throughput to the LUN. I found iozone, but I'm having a devil of a time with it.

I have acer aspire one netbook with synatics ps2 touchpad. It works fine, but I'd like to emulate left button by just pressing somewhere in the touch area (same as it works in windows or ubunntu). I think this is called tapping. How can I configure that? I have been in touchpad settings and management, but I have not found any checkbox helpful. In OS 11.3 I need to press left button next to the touchpad.

Using a fresh copy of server 10.04 im trying to simulate a failed raid array on a pair of 2tb disks. Here is the procedure i have been following so far:
- Remove the dead disk partitions from each of the raid 1 arrays (substitute the correct md devices and partitions)
- mdadm /dev/md0 -r /dev/sdb2
- mdadm /dev/md1 -r /dev/sdb3
[code]....
I get an error here that sfdisk does not support gpt (guid partition table). I thought sfdisk did support gpt? It says to use parted, but i cant find a command that copies a partition table over from another disk in parted documentation. Any suggestions? I suppose i could make the partitions manually, but im writing a procedure for people who arent that technical and i need it to be simple enough to be run in my absence. manually building the partitions would be too hard for them.

I'm trying to simulate a script for two UES connected with a high speed common channel. The file is the same I've used in not enhanced umts with some changes, and it worked perfectly. The changes are indicated in the EURANE guide.
There are two lines of code:
Code:
$bs setErrorTrace 0 "UE1_trace_file"
$bs setErrorTrace 1 "UE2_trace_file"
that give me an error when I try to run the file .tcl
I've downloaded files I needed from EURANE page: SNRBLERMatrix and Ray_corr-3kmh-300m-0-200s-UEnr1,Ray_corr-3kmh-500m-0-200s-UEnr1,Ray_corr-3kmh-700m-0-200s-UEnr1
I've tried to use the first and the third for UE1 and UE2 respectively
[Code]...
I edit: The definition of the connection of TCP agents and sinks was incorrect.

I want to simulate a serial protocol in user space program to test reception algorithm. The protocol is similar to UART protocol but frame format is different. The duration of 1 bit is 114,46 us. In my main function I'm creating two threads. Tx for simulating transmitting data and Rx for reception data. For measure time I use create_timer() function and signals. Each thread has its own timer and signal handler. Tx timer uses SIGUSR1 and Rx timer uses SIGUSR2. Tx thread sets the global variable and Rx reads it.
The timers are set to sample with 114,46 us period. When they reach this value signal handler should set the flag. Flag is check in thread and some operation are made. When I set the timers period for longer time (100 ms) everything works fine but when I change it to default value (114,46 us) the Rx thread doesn't receive the proper data. I am wondering if the 114,46 timer period is possible to simulate in user space? Whether the time will give me the proper resolution ? Theoretically it should provide 1 ns resolution.
