I am having a problem with sound in a range of applications. Playing an mp3 file is OK for 30 seconds or so, and then it seems to skip and make crackling noises. Stopping and replaying the file causes the same thing to happen again. I have installed all the mp3 codecs so i'm not sure what's going on.
View 14 RepliesI am not a networking expert by any means (in fact I have never taken a networking course), but I have taken several security courses, and generally we wind up discussing replay attacks. For example, the Needham-Schroeder protocol (using symmetric-key cryptography anyway) is flawed because it allows for replay attacks, and I understand why.
I guess my question is actually how someone would perform a replay attack. I know I can sniff network traffic by downloading wireshark. I also have downloaded winpcap and npg on my WinXP virtual machine. I'm trying to use this guide to help me, but I'm quite lost:[URL]What I did was to post a "link" to my facebook profile and I sniffed the traffic using wireshark. What I would ultimately like to accomplish is to copy that packet out of the wireshark output, and then use a tool like npg to transfer the raw packet back to facebook, which should result in a second, redundant post. I just can't figure out how to do that.
I'm pretty sure this should be possible. Facebook only uses an SSL session for authentication during login. After that, the information is just sent in the clear, so I'm pretty sure this should be possible.Can anyone explain how to do such a thing? It would really help my research paper that I'm working on this semester if you can. As of right now the attack we are trying to demonstrate/defend against is using a Windows VM, which is why I'm using winpcap/npg. The attack is actually possible using just about any OS (depending on the exploit used), but our POC is Windows only at the moment

Boot of a new minimal system hangs on "Stopping save kernel messages" or "stopping system v runlevel compatibility". I have ubuntu minimal iso x86_64 from usb stick created with unetbootin (don't have a cd drive on the machine in question), and after that I didsudo aptitude install gnome-terminal network-manager-gnome gdm geditsudo rebootnever got a system back. Annoyingly I can't boot into the recovery mode either, and it seems the keyboard is only semi-responsive (i.e. many dead keys when at the grub menu).qualms about reinstalling, but I've done this a few times and ended up at the same place every time.

I notice that when I leave my machine and come back the screen has locked. I have tried to turn off the screensaver, but it hasn't worked. I have Googled, but unfortunately the screen shots don't look like what I have and the instructions to stop this do not seem to match what I am seeing on the screen.
Is there a way to do this via the command line?

View 2 Replies View RelatedI want to modify ioctl TIOCMWAIT to return the same thing that ioctl TIOCMGET returns. Currently wait returns an int of zero or -1 when a change in status occurs. Why not make it return the new status?
This will make the operation faster by not requiring another call to ioctl.The extra call requires 2 to 16 uSeconds to complete on my x64 laptop. How would I make this proposal to the kernal people?
Its on an older laptop, a Toshiba Sattelite M50-252. A friend of mine had this laying around, and it wasn't running windows very well. So I installed Ubuntu 9.10 on it and it was performing decently enough for browsing and mailing.
On Ubuntu 9.10 there was a problem sending large images for printing. It would make the printer (A brother HL-4050 CDN, placed on the network) say out-of-memory. Same print job from windows would not make this error. Upgrading the system to Ubuntu 10.04 worked.
Actually, I had before tried 10.04 on the machine but ended up formatting and reinstalling 9.10. This was because browsing on 10.04, no matter what browser, would simply hang randomly. A search on google could be performed, and some pages loaded. But some pages didn't load at all or only a few % of them, and the browser would just claim to be "resolving host".
On 9.10, on all 3 installs i've done on the machine, this problem was NOT to be found.
Here goes the real issue: 4 days ago I installed 10.04 to test again(6 months after its release, lots of updates has been done), and browsing worked great. The laptop has been used a lot since then and now yesterday it started stalling again. The most interesting thing is that APT-GET works fine. New software downloads with a snap. Also WGET with a single file works (although it seems to hang at the resolve once in a while).
Why on earth did it suddenly start to behave like this? Nobody with even the knowledge of using SUDO has been using the machine and it has been used ONLY for browsing. Automatic updates are disabled as well. Even weirder, this happens both using the wireless network card and cable.
I have no idea whats going on. Ubuntu 9.10 works always. 10.04 worked the second time (after a few months of updates) but started stalling after a few days. The system itself runs perfectly well, and there is nothing wrong with apt-get and so on as i said.
I want to resize and eventually remove some partitions on my drive but I need to know how this will affect grub and what to do if I need to fix it.I currently have 3 standard partitions and 1 extended partition on a 160Gb drive.
1st Partition -Windows XP about 60Gb with about 35Gb used. NTFS
2nd Partition -Ubuntu Lucid 10.04 amd64 about 40Gb, 22Gb used ext4
3rd Partition -Linux swap about 2.5Gb
Extented Partition -Ubuntu 9.10 about 49Gb with 23Gb used ext4
I'd like to shrink the Extended partition down and add the space to the 2nd partion where Lucid is. Eventually, I'll want to delete the whole extended partition and add all the space to the Lucid partition.
After using GParted to resize these partitions, what will happen when I boot? Will I need to tell grub where the swap and 9.10 are? I am not changing the start of the first two partitions so I would assume there will not be any problem with them (I'm not sure how moving the start of the swap might affect the Lucid installation though).
i am considered a power user in windows but in ubuntu ima total noob. in the users settings, manage groups, i see like 100 groups. and thats just annoys me, all i want is to be the admin and everything to work its not rocket science is that so hard for linux?

1) does it overwrite existing configuration files that is will i need to reconfigure every service after running yum update
2) If somebody pushes the reset button or electricity to the system is reset while yum update is running what will happen i think there can be two stages to that
a) if it is still downloading while the electricity to system is reset
b) it is installing while electricity to system is reset
