Trying to install 10.10 netbook edition on my MSI U230 netbook from a USB drive. Keep getting the error "hyper transport sync flood error occurred on last boot" Press F1 to Resume. F1 causes just a reboot and the same thing happens. Anyone seen this error? It happens with both the netbook and desktop version.

my problem is: i wanted to repartition (shrink xp and create partition for data storage) my hdd using gparted live cd 0.5.2-9. everything went fine until i clicked exit and reboot. after the cd tray automatically ejected i got a flood of "VFS: busy inodes on changed media or resized disk srO". this doesnt stop until i press enter. after that it reboots normally and there is no problem with the os.
my questions: 1) is that flood anything bad, is there a way to avoid this. i read somewhere that the problem is solved when using the terminal sudo eject - then push back the cd tray - then sudo eject -t. i tried that but it said failed because gparted cd is in use.
2) the first time that happened i didnt know what to do, so it flooded like for 15min or more until i pressed enter. my question is if the flood is being saved anywhere on the pc so that i have to delete it?
and a question regarding extended partition: 3) i have 50gb left that i want to use for data storage. i read that you can only have one extended partition. so since there is already one extended partition from ubuntu, i cant have another one for windows? so i can only make the data partition as primary or is there another reason why the "create extended partition" is greyed out?
last question: 4) when i set up the partition for swap i made it 1032gb big but in gparted it shows 980.53mb. is that still enough or why is it like that because somehow the sizes of the partitions seem a bit different than how they originally should be. im actually used in seeing the size shrinking a bit but i found it weird that the ubuntu partition shows 4.76 when it should be 4.5gb. i know its not much different but im just curious to know why..
partitions order: windows - unallocated (-->data partition) - ubuntu (primary) - home folder (extended) - swap
in windows the partitions are shown as: windows xp (31,74gb) - unallocated (50,05gb) - 4,76gb unkown - 24,27gb unkown - 981mb uknown
in gparted: its almost the same, only difference: there is unallocated space (7 or 8mb) between home folder and swap

how to do iptables log to file UDP Flood under 64 packages?
View 14 Replies View RelatedBanning the IP is the best way to protect your server but of course, attacker can use another IP and use a lot of your bandwidth until you find and ban the IP. So the only thing we can do to prevent this is, block the packets my iptables length module.
I check the bandwidth usage through "iftop". Incoming traffic is always like 120kb/second and that has to be that way because the traffic enters my server no doubt that it gets dropped by iptables later.
The actual thing what the Ddos ( UDP Flood ) does it that it causes an outbound traffic that eats up like 5mb/second easily and my servers lag. Only if the IP is banned, the outbound traffic comes to an end.
Now I want to use the length module to block it but it just won't work. I've tried the following and shuffled them too but no help.
Code:
iptables -I INPUT -p udp -m length --length 15 -j DROP
iptables -A INPUT -p udp -m length --length 15 -j DROP
Packet length is 15 according to tcpdump:
Code:
19:49:34.504864 IP fms-02.colt.net.belgamanagement.be.56413 > nyc.v1servers.com.20100: UDP, length 15
my computer froze solid, and it would not react to anything. X didn't react to Ctrl+Alt+Backspace, not Ctrl+Alt+Del, so I had to turn it off using the power button.
This is the first time my computer freezes like this, the log files did not reveal any HW errors. Is it possible that someone in the channel did not like my level of Java skill, and flooded me to disconnect?
By the way; Im using slackware 13.1 with the default kernel (2.6.33.4) and irssi as IRC client.
I know that if you eg. ICMP-flood someone, the traffic will be denied and, but can it provoke other behavior from the computer?
So my question is; can a IRC flood/DDoS attack cause a computer to freeze sub zero?
I run a Centos server that quite a few people have access to. I trust every user on the system, but i've had problems before like one user's account gets hacked and someone starts using my box to DDOS. Each user has their own ip.. And I would like to write a script or use an existing solution (if one exists) to monitor number of tcp/udp connections each minute and see if it's unusually high. I don't want it to stop the flooding or anything, I just want to be notified by email or something.
View 1 Replies View Relatedone thing I'm not quite certain about is suitable limit rates for SYN, LOG & ping flood prevention. I suppose it depends a bit on traffic, as well as bandwidth. However, I don't want to limit the former. FWIW, I expect about as much traffic as a country road in the middle of nowhere, and my bandwidth for requests is 15 Mbps (Don't laugh. Content delivery is a pathetic 2 Mbps. That's a residential cable connection for ya...)Of all the tutorials/examples, I chose to go with Rusty Russel's limits, though they're dated 2002. Thus an excerpt of my firewall "script":

Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps, the parameter is the maximum samples per second by which the audio is changed. -async 1 is a special case where only the start of the audio stream is corrected without any later correction.Searching the net makes one believe that this command is just some sort of magic.People just put it in the line and it just works. Isn't that nice?
It says nothing about how to change the TIME the audio starts syncing. Like do I want it to start 5 seconds delayed? Or what about 5 seconds sooner?What if the audio gets more out of sync as the video goes on? Can I slip it a little at a time? What? No magic?No one mentions a file that already has badly synced audio.So what -async 1 really does is simply start the audio at the beginning of the file. LIKE AS IF THAT ISN'T STANDARD PROCEDURE?So what is the exact solution to syncing a messed up video? And why can't it just do the proper "timestamp" sync in the first place?No docs, no info and you are left out in the cold.
I'm trying to run Mac OSX Leopard + Ubuntu on my Macbook White 4,1. I've read multiple user guides, but for some reason it screwed up when I hit the partition button on rEFit. I received the 'gpsync' (sp?) error. I couldn't delete any of my partitions or make them go back to normal... As we speak I'm wiping my hard drive. I would really LOVE to start over FRESH. With Mac OSX, then to install Ubuntu. How can I go about installing Ubuntu on my Macbook without getting the sync error, and screwing up my partitions. Yes I read the user guide, and yes.. I did it step by step and still received the errors. I would love to fool around on Ubuntu, but the errors were stopping me.

I have a CentOS 5.3 server. All of the other computers I have are Windows or Ubuntu. The Ubuntu machines sync to the time on the CentOS machine correctly. The problem is, some of the windows 2000 Pro and Windows XP Pro machines are an hour off when they sync. The CentOS machine is set to New York time.
When I run: (Assume the time is currently 10:06 AM on the server) net time \xxx.xxx.xxx.xxx /set /yes
On the correct machines I get the message:
Current time at \xxx.xxx.xxx.xxx is 11/1/2010 10:06 AM
The command completed successfully.
But on the other machines I get:
Current time at \xxx.xxx.xxx.xxx is 11/1/2010 9:06 AM
Local time (GTM-04:00) at \xxx.xxx.xxx.xxx is 11/1/2010 10:06 AM
The command completed successfully.
Then the time on the windows computer is 9:06 instead of 10:06.
Is there something that needs changed on the CentOS Machine for the times to be correct?
I use jpilot on opensuse 11.3 64bit to sync pim data with my Palm Treo 680 via bluetooth. This worked fine until today. Now I get the following error message when I try to sync: Syncing on device bt: Press the HotSync button now dlp_ReadSysInfo error Exiting with status YNC_ERROR_PI_CONNECT Finished.
The last successfull sync was on the 20th October and today is the 24th October. I did not change any settings in jpilot or on my palm device. So I guess there must have been an update of opensuse which causes this error. But I do not now how to look up the updates during this period or how to undo them. Was there an update between the 20th and the 24th Oktober, which might affect either jpilot or bluetooth functionality?

I have a production box I am trying to get CA's XCOM transport utility running on. I have been able to successfully transmitt a file but on a receive I get the following error.

I do have a ticket open with CA and they are doing there best to assist me, but this is not a supported version, they only support RedHat distros. They want to know what the equivilant RedHat kernel is to my CentOS install. I guess my biggest question is: Anyone out there running XCOM on CentOS? I searched and searched and can't find anyone else running XCOM like this. It's hard to believe I'm the only one out there trying to do this.
I am running an installation of Scientific Linux 6.0 (it is literally RHEL 6 minus the brand), and have successfully setup Citadel Groupware, and synced it with a Mozilla Thunderbird client with the Lightning calendar extension. It is very nice!
However, for the Citadel server to sync with my iPhone, I need to, and have have downloaded and successfully started the latest Groupware Sync Server from here. The Groupware Sync Server is basically an installation of Funambol, specially made to work with Citadel.
I tried to connect to the server from my iPhone with the Funambol connector app, and the Synthesis SyncML app, but none of them worked when I pointed them to: http://[hostname]:8080/funambol/ds (which is what the Groupware Sync Server documentation told me). Of course, I replaced [hostname] with my actual hostname.
I checked the logs of both sync apps, and they both say the following:
Quote:
[ERROR] processItemStatus: server sent status 506 in SYNC
[ERROR] Error #506 in source addressbook
On the Citadel and Groupware Sync Server forums, I was told that error 506 meant its something on the server going on, so I got the two relevant log files, /opt/Funambol/logs/ds-server/ds-server.log, and /opt/tools/tomcat/logs/catalina.out (the links point to pastebins of the output).
What does "error 506" mean, and how do I correct it?
BTW, I disabled my entire firewall just in case that was the issue.
I'm new to ubuntu but i do have a basic understanding of programming, but nothing too serious. The reason I am mentioning this is because I have a little project. Currently I use JACK to control the transport of all the aps i use to make music with ardour, hydrogen and rosegarden mainly. I also have an external midi drum machine that I sometimes hook up into the mix via midi in/out, my drum machine (yamaha ry to be exact can send and receive midi data. My question is can I use the transport controls on my external drum machine to control JACK's transport controls? If there is already am app that does something like that, excellent!

View 2 Replies View RelatedI installed 10.04 on a Hyper-V virtual machine and a few hours later discovered that the server was unusually sluggish. Top revealed that ksoftirqd was sucking up around 97% CPU. Reading up on the issue focused on earlier kernel issues, which I knew didn't apply to 10.04. I eventually discovered that I set two CPU cores in Hyper-V. Decreasing this to just one CPU solved the issue.
