General :: Data Written To Unformatted Disk

Jan 14, 2011

I went and fdisk'd a USB disk and put the Fat32 filesystem onto it. Then I thought I ran dosfsck over it which I thort formatted the disk - apparently not. Then I copied a bunch of files and directories to it. Now I am unable to recover the files and data. In the rare instances when I perform a sloppy mount I see directories named 001, 002, 003 and 004. These directories variously contain files named 001, 002, 004 (no 003) etc.

Fdisk gives me:

I don't know enough to use dd, kpartx, parted, partmon, partprobe, partx et al

General :: "written Data In Track 1 Differs From Original"

Mar 3, 2011

I just tried to burn an ISO to a CD-R in K3B, and it finished with the message "written data in track 1 differs from original." I get that a lot; until now, I blamed it on my failing CD drives . What can I do to avoid it besides burning at a slow speed? I know that, having heard years ago that I should burn at 4x; but my new DVD-RW burner's slowest writing speed is 16x. (I'm annoyed at that. It was a Christmas gift, and I didn't think of specifying a write speed. I wouldn't be surprised if new CD drives can't burn at such a slow speed, though.)

General :: /var/log/messages Is Not Being Written To?

Nov 1, 2010

I was attempting to get crontab to kick off a daily job, but the job wont start. I opened /var/log/messages and noticed all the logs were from 6 months ago. I cleared the log and then did a tail -f so I could watch it for activity. I then hit my box with anunsuccessful log in attempt. Nothing happened to the log. The uptime of my box is 22 days and the logs that were in it before I cleared it were from months ago.Is there a daemon I can check or another file I can mod to get logs writing again?

Ubuntu Servers :: Monitor Data Usage - With A Proxy ?

Jul 3, 2010

Is there something which can act as a fully fledged proxy (exactly like squid) but which can also monitor data usage?

At the moment what I do is I log data usage of IP addresses (allocated by DHCP) by using IPFM. Obviously getting a new IP address from a DHCP server isn't hard and this could be abused.

So I was thinking if I require proxy authentication and log usage that way, there is no way for anyone to abuse the system.

Does anyone know of a proxy server capable of logging data usage?

Ubuntu Networking :: Bandwidth Monitor - How Much Incoming Data Had In The Last 24 Hours

Feb 18, 2010

I'd like to find some sort of program which can tell me how much incoming data I've had in the last 24 hours. It goes by hours, not by days, but anything that's simple and that can display this will do. Is there any sort of program that does this? Something that would fit well with Ubuntu's style wouldn't hurt, but I'm not that worried about it as long as it does the job.

Programming :: Getting A Script To Continuously Monitor Appended Data To A Log File?

Oct 13, 2010


if ! [ -f ${PATH}/myfile.txt ];then
echo $(date +%Y%m%d"_"%H%M%S)": Nu am gasit fisierul ${PATH}/myfile.txt"
ps -fxu pin | grep "/usr/local/coreutils/bin/tail -f ${LOG_PATH}/x.log$" | awk '{system("kill "$2)}'
cat ${LOG_PATH}/x.log | sed -n -e '/LONG/{x;1!p;g;;}' -e h > ${PATH}/myfile.txt


I have a continuously growing log file (x.log) in which i have to look for certain lines that contain "Long". The line above each line containing the word "Long" it contains a time stamp. I want to extract each line containing the time stamp into myfile.txt and check the difference between time stamps. Whenever there is a difference i need to run another script (${CAL_PATH}/${APP_NAME}), then sleep 1, then continue searching. Lines with "Long" do not appear continuously, but in blasts. The script runs fine until the first pause encountered. Starting with the first pause, tail -f doesn't write in myfile.txt anymore. Can someone help me understand why "tail -f" it stops writing into myfile.txt? Or does someone know an alternative to "tail -f" of achieving the initial scope of the script?

Programming :: Monitor Temps And Values Fed In From A Data Acquisition Device

Feb 7, 2010

I'm thinking of a web based app that will monitor temps and values fed in from a data acquisition device but am seeking advice on what to use to produce the web page would php be powerful enough? The app will also have to have access to a shell for scripting, I know thats a security risk but it will not be in an exposed env. The web page will have a series of lcd readouts displaying the aquired data refresh rates will probably be around 5 seconds along with control buttons to turn on and off values. Storing data in a mysql database for statistical reports would be needed eventually. Ubuntu 9.10 will be the os. Is python easily integrated into apache?

Ubuntu Networking :: Traffic Monitor - How Much Data Downloaded/uploaded On An Interface This Month And Previous Month

Nov 20, 2010

I'm looking for a powerful network traffic monitor that can do all of the following (or at least a combination of tools that can do the following):

Tell me how much data was downloaded/uploaded on an interface this month and the previous month tell me how the traffic was used throughout the monthshow which internal IPs (IPs in the network) used how much traffic show which ports/protocols on those IPs used all that traffic

Hhow LIVE traffic flow statistics that can tell me total speed of traffic going through an interface as well asshow which internal IPs (IPs in the network) are using how much of the traffic show which ports/protocols on those IPs are using that traffic

This tool will run on a linux router through which all my internal PCs are connected to the Internet. This means the tool(s) need to work with NAT (traffic being forwarded and not necessarily destined for the interfaced being monitored).

The distribution being run doesn't have a package manager so any packages or dependencies have to be manually compiled and SCPed over file by file. For this reason, the tool/tools need to be simple (things like vnstat, not things like ntop that have their own web interface).

I know that vnstat can tell me the first bullet point so it's only there incase there's a tool out there that can do everything. If there's a tool that can only do the second or third bullet point, that's great too - I'll just keep using vnstat and look for something else to do the other task.

Ubuntu :: Nothing Written In Fstab ?

As you can see my fstab is blank, I was just wondering, is this a problem? Or is it totally normal?

Fedora :: Verifying Files Written To A DVD?

Dec 26, 2009

I've been having trouble writing to DVDs on one computer, and I am trying to figure out whetgher the problem is hardware or software related, or, perhaps, both. The brasero CD/DVD writer puts the md5 checksums of each of the original files in a hidden file on the DVD. I think it then calculates the sums of the copies and compares, but the last time I did it, it told me it had permission problems with the drive, and that failed. When I put the DVD in, udev finds it and mounts it in /media with me as its owner. Apparently, brasero mounted it some other way, and presumably that caused the problem.

Secondly, after I brought it up again, I went into the /media mount point and did md5sum on the files there. One of them a gzipped tar file, produced and input/output error. Yet if I use cmp to compare that file with the original it finds no difficulty. So what is going on? Finally, I have tried to write shell scripts which use cmp to compare the original files with the copies. The general form is

find $* >> /tmp/X
for i in `cat /tmp/X`
cmp $i YYYY/$i

where XXX is the mount point in /media and YYY is the original directory containing the relevant files. This works fine except that if the file names have spaces in them, the shell script treats each word as a new file name. So I need some way to arrange things so that `cat /tmp/X` returns the complete file name. Nothing I've tried works.
