• File creation time on Windows vs Linux

  - by Sergei

  We have following setup: mountserver - debian linux fileserver1 - Windows 2008 R2 Storage server fileserver2 - Celerra NS20 exporting CIFS share workstation - windows 7 with mapped drive to share on fileserver2 What we are doing: mounted share from fileserver1 on mountserver, e.g. /shared/fileserver1 mounted share from fileserver2 on mountserver, e.g. /shared/fileserver2 ran rsync on mountserver to sync data from fileserver1 to fileserver2.Used atime as parameter to sync data not older than X after a while tried to delete data older that Y on /shared/fileserver2. From what I see, linux stat command on mountserver returns following when quering file on /shared/fileserver2: At the same time when I open property for the same file using mapped drive connected to fileserver2,I see following for the same file: As you can see, Created date of 12 August shown in Windows Explorer is nowhere to be seen using stat command Am I missing something here?

• Are there any free voice transcription software?

  - by netvope

  I have some 1-hour-long voice recordings containing useful information that I may need to look up in the future. Instead of transcribing them myself (which will take me many hours), I want to automate it using software. I don't need an accurate transcription; it's OK as long as I can get an idea of what was being talked about by skimming over the transcription. With this, I can quickly figure out which part of the audio contains the information I need, and is much more convenient than seeking randomly. In theory I could write a program to split the audio into 3 minutes chucks and pipe them into Google Voice's free voicemail transcription service... But I hope there are better solutions. Do you know any free voice transcription software? Note: Free trials are also acceptable

• Port 53 UDP Outgoing flood

  - by DanSpd

  Hello I am experiencing very huge problem. I have 4 computers in network, and from each a lot of data is being sent to ISP name servers. Sometimes data is being sent a little from each computer in network, sometimes it is just a lot of data from one computer. I have antivirus (Avast) and malware scan (SpyBot) I know port 53 UDP is dns which resolves domain IP so its' needed. Also I have read that ISP name server might have been infected. So what is the best thing to do in this situation. Also sometimes internet starts to lag really because of port 53

• Using Gentoo's `ebegin`, `eend` etc under Ubuntu

  - by Marcus Downing

  We're quite fond of the style of the ebegin, eend, eerror, eindent etc commands used by Portage and other tools on Gentoo. The green-yellow-red bullets and standard layout make for very quick spotting of errors, on what would otherwise be very grey command line output. #!/bin/sh source /etc/init.d/functions.sh ebegin "Copying data" rsync .... eend $? Producing output similar to: * Copying data... [ OK ] As a result we're using these commands in some of our common shell scripts, which is a problem for the people using Ubuntu and other linuxes. (linuces? linuxen? linucae? other distros) On Gentoo these functions are provided by OpenRC, and imported with functions.sh file (whose exact position seems to vary slightly). But is there a simple way of getting these commands on Ubuntu? In theory we could replace them all with dull echos, but we'd rather not?

• ganglia graphs like munin for cpu, etc?

  - by CarpeNoctem

  I'm coming from munin and a CPU graph contains data for system, user, nice, etc ALL on one graph. I just installed ganglia and setup the basic monitoring. It appears that each type of cpu data is a separate graph! WTF is this and can I change the defaults to combine these into a single per host? That is my question, how do I combine cpu data into a single graph. Also, can I change the layout to something closer to munin's day-week side-by-side layout? I'm trying to be impartial and give ganglia a chance. ;)

• Weather Logging Software on Windows Home Server

  - by Cruiser

  I'm looking for some weather logging software that I can run as a Windows Home Server add-in, or as a service on my Home Server, so I don't need to log into my Home Server to log weather data. I have an Oregon Scientific WMR918 weather station, and an HP MediaSmart EX485 Windows Home Server. The two are currently connected through a serial bluetooth adapter, but that shouldn't matter as the computer sees it basically as a serial device. I'm currently using Cumulus to log data and upload to Weather Underground, but it is a regular windows application, so I need to remain logged into my Home Server by RDP in order to run the software (I disconnect, but don't log off so the session remains open). Ideally I would like something to run as a service or WHS add-in, so that it runs all the time without logging in, can log data from my WMR918, and can upload to Weather Underground. Thanks!

• In TCP/IP terms, how does a download speed limiter in an office work?

  - by TessellatingHeckler

  Assume an office of people, they want to limit HTTP downloads to a max of 40% bandwidth of their internet connection speed so that it doesn't block other traffic. We say "it's not supported in your firewall", and they say the inevitable line "we used to be able to do it with our Netgear/DLink/DrayTek". Thinking about it, a download is like this: HTTP GET request Server sends file data as TCP packets Client acknowledges receipt of TCP packets Repeat until download finished. The speed is determined by how fast the server sends data to you, and how fast you acknowledge it. So, to limit download speed, you have two choices: 1) Instruct the server to send data to you more slowly - and I don't think there's any protocol feature to request that in TCP or HTTP. 2) Acknowledge packets more slowly by limiting your upload speed, and also ruin your upload speed. How do devices do this limiting? Is there a standard way?

• SQL Server Replication Agent priority

  - by Wikser

  Every hour a server replicates SQL server data with some external web server. During this time, which takes about 2-5minutes, the database seriously slows down. Colleagues, which work with the front end applications of that on another terminal server, even regularly start complaining. The databases are also synchroniously mirrored (via SQLServer mirroring, no replication) to a third server. Note that 99% of the data is replicated outgoing, so the server should rarely need to update its data. As the (merge and transactional) replication tasks are not time-critical, I would like to reduce their priority or somehow slow them down, so they don't affect the database performance that much. How would you implement that?

• What does this WinImage Error Mean?

  - by Kryten

  Hi, I am using WinImage (version 8.0) on Windows XP SP3 to create a VHD File from my Hard Drive, however, everytime I try to, everytime it says: "I/O error in reading data on position 000000007cd40000:00010000. Error 23: Data Error (cyclic redundancy check)." with the options "Abort", "Retry", "Skip" & "Skip All". Everytime I try "Retry" the message comes, if I click skip another message comes up (same as above, except the data position). I have run "CHKDSK /F /R" several times, but the error always appears. What is wrong? Can I safely skip the Errors? Is there anything I can do to fix the error?

• How is it possible that Winrar can repair any volume with one .rev file?

  - by Coldblackice

  I just learned about .rev files with Winrar -- that if you have a 10-part RAR volume, for example, plus one .rev (recovery) volume -- that .rev volume will be able to "fix" any -one- corrupted volume. How is it able to do this? Obviously there's something I'm not understanding, as I don't understand how one volume could have the "data" to fix any/all of the individual broken volumes. I'd guess that it's because the volumes aren't broken up like I tend to imagine -- each volume having individual files of the whole packed into them, but rather, it's viewed as one continuous "file", so to speak, of data. And that there must be some type of CRC'ish repair work -- But I just don't understand how you could have 9 working volumes, with 1 damaged, but a recovery volume that would be able to repair -any- one of those volumes. How is it able to hold "all" of the data in just one recovery file?

• Beginners advice on Small business network disk(s)

  - by Rob

  We are having 10 PCs used by various user and presently use one network disk (a LaCie NAS) for all our data. Everything is Windows Vista and our collective IT hardware knowledge is minimal. This worked well generally. However, recently the disk freqently loses connection from the network (2-3 times per week) and the only way back seems to be the "turn it off and back on" trick. This obviously cant be any good for the disk. I understand that there are various more sophisticated ways of storing data and was wondering what people would recommend. One of the worries is obviously disk failure (either in part or as a whole) and the lack of continued availability due to network issues. I would guess that a disk which replicates data wouldnt work as a sole solution due to the network connection, but dont know what hardware (and/or software) would/could work in our case. In terms of size, we are looking at very small amounts, ie. less than 500 GB in total.

• redundant/multi-site terminal server

  - by Adam

  Hi We have a Hyper-V cluster running 5 virtual terminal servers using HA. We need to be able make this system redundant and so if this site was to fail our users could log into the backup system at another location and access their data via the terminal servers. Any ideas? We were thinking of maybe using a NAS which replicated the data to the other location in real-time(pass-through disks)? and having a similar Hyper-V cluster setup in the backup location. However we would need to create the users in both location and create a virtual mirror without the data ie applications, directories, settings etc. Is this the best way to achieve this? We have read that using Hyper-v pass through disks is a big performance de-grade.

• Snow Leopard, PHP, and MySQL

  - by Peter

  I have just installed Snow Leopard and now my PHP/MySQL program ends in a "Segmentation fault". I have been searching the web for a solution, I realize that there are some issues with SL/PHP/MySQL, but I have not found anything that works yet. I downloaded the binary MySQL package mysql-5.1.42-osx10.6-x86_64. I have updated the php.ini file as suggested at various posts. When I run PHP and connect to the MySQL server the behavior is a bit random. In many cases it works fine to connect and read data. In my specific case the PHP program constructs a LOAD DATA LOCAL INFILE ... statement to load data from a text file. It should do several such queries after each other in a loop. It works one time but the halts in a "Segmentation fault". The program worked fine in Leopard, but not now. My versions are: OS 10.6.2, PHP 5.3.0, MySQL 5.1.42

I want to run program test.exe located at C:\data\test.exe and to use dir. C:\data so it could use other data in relative path. so test.exe would access file .\file.txt without using absolute path Hope I wrote it understandable, sorry for bad English.

• why do i get an SPF Softfail?

  - by johnlai2004

  I installed SPF on my LAMP server with postfix. But for some reason, I get this error Received-SPF: softfail (mta1070.mail.re4.yahoo.com: domain of transitioning [email protected] does not designate 1.1.1.1 as permitted sender) I have two questions: 1) how do I trouble shoot this error 2) I've been looking through my configuration files in an attempt to change [email protected] to [email protected] because anotherurl.com has the correct SPF TXT records. Where do i go to change this? I tried editing myhostname under /etc/postfix/main.cf, but it didn't do anything.

• how to setup sonicwall tz210 to port forward packets received from external ip to another external ip

  - by lplp

  i have a sonicwall tz210 on a fixed ip, say ip1. And then i have, let's say a legacy server, with external ip ip2, which sends data to ip1 (and I have another server on ip1 behind the sonicwall which receives and processes that data). I would like to set up a new server on a different external ip ip3 that will receive and process data from the legacy server. How can I setup the sonicwall so that the packets received from the legacy server (from an external ip) are port forwarded to the external ip address ip3?

• Can someone correct me about Windows 2008 DFS implementation

  - by cwheeler33

  I have 2 two Windows 2003 file servers using DoubleTake at the moment. They are in an 2003 AD domain. And each server has it's own disk set. It is time to replace the servers... I want to use Windows 2008 64bit Ent. I was thinking of using DFS-R to replace DoubleTake. The part I'm not sure about is clustering. Do I need to have shared storage if each server has a copy of the data? I want to have the data available to the same share name, so maybe I don't fully understand how DFS is set up. I currently have about 6TB of data. I expect to grow by 3TB a year on these file servers. Any resources/books that could teach me would be good to know as well.

• Centralize proxy settings for all the application on my workstation

  - by Leonardo

  As a consultant, I used to work at different clients premises. It happens frequently that most of them has specific proxy settings, but not all the application I have installed on my laptop get settings from system preferences, for allowing me to change settings in one place. Some of them bypass system preferences completely, proposing their own mask for entering specific data such as username, host and password. I am looking for a convenient and not much intrusive way to share a common access point on which I could enter data, and maybe persist them. An 'automatic' switching would be ideal, for example based on some network identification, but there's no problem for me to enter data manually. I am not an IT expert, but to explain myself clearly, I am looking for a solution like .pac file is for browsers. Relevant OS I am using are MacOSX and Linux (Ubuntu).

• environment variable issue in shell

  - by George2

  I am using Red Hat Linux Enterprise 5. I know the theory that -- using export to set environment variable, the environment variable will apply to current and child environment, but without using export to set environment variable, the environment variable will only apply to the current environment. My confusion is, what is the exact definition of "child environment" and "current environment"? For example, $ var1=123 $ echo "Hello [$var1]" the value of var1 (which is 123) is printed in shell, but I think echo is a command invoked by current shell, and it (the echo command) should be a child environment of current shell and the value of var1 should not (because not using export var1=123) impact echo. Any comments? Thanks in advance!

• Excel graph: turn stacked bar chart into part bullet chart

  - by Mike

  I've a simple data file that has one column of actuals and another of target against categories. I would like to turn the TARGET figure into a 'Bullet marker'. I've seen it done on other graphs but I'm struggling with the category column being overwritten with the xy axis values. Or if I get close to doing it then the xy markers are not central. I've checked out Peltier but his examples are based on even more comlicated data than mine, so the steps required didn't seem to match up. Help greatly appreciated. Thanks Mike.

• Is Family Tree Maker 2011 the right upgrade?

  - by bill weaver

  My father has used Family Tree Maker for years, but hasn't upgraded since version 11. It is difficult to tell from reviews at Amazon and other places whether upgrading to FTM 2011 is a good choice. File incompatibilities and upgrade woes sound like customer service is lacking, and i've read reports of it uploading your data to their database but then trying to sell you a download of data. Looking at the ancestry.com site makes me think it's solely about selling add-ons and upgrades. On the other hand, the feature set seems fairly rich and the software has a pretty strong following. I was able to get Gramps working on my system, but that's not going to work for my dad. Any advice on a good upgrade path? Doesn't necessarily have to be FTM. The only requirement is a way to import his existing data.

• Unset the system immutable bit in Mac OS X

  - by skylarking

  In theory I believe you can unlock and remove the system immutable bit with: chflags noschg /Path/To/File But how can you do this when you've set the bit as root? I have a file that is locked, and even running this command as root will not work as the operation is not permitted. I tried logging in as Single-User mode to no avail. I seem to remember that even though you are in as root you are in at level '1'. And to be able to remove the system-immutable flag you need to be logged in at level '0'. Does this have something to do with this issue?

• Audio and video streaming using Network Simulator in Linux

  - by Parth_90

  I am working on a project which is to show the simulation of streaming of audio and video data in wireless networks. I want to show the simulation that involves a base station, with few wireless stations. The base station should start sending data once it computes a certain value . On receiving the data, each wireless must begin communicating with the base station. I have gone through basic NS-2 tutorials from over here but I am not getting how to go about integrating it with my project. Can anyone tell me how to do it using NS2 or any other network simulator?
