• Real RAM latency

  - by user32569

  Hi, very quick question. When I look for RAM timing, I got 2 different explanations on what is CAS latency. First states, its the time after command to read has been issued from CPU and data are send to data bus. Second says its time betwen column in memory layout has been activated. So, where is the truth? I mean, when I want to know total RAM latenci, in case 1, ot would be just CAS times one clock time. In second case, it would be CAS+other things like RAstoCAS and so times one clock time. Thanks.

• What does the [0/0] indicator mean when entering copy mode in tmux?

  - by bps

  When entering copy mode in tmux, an indicator in the upper right corner shows "[0/0]". I can't find any documentation in the man page about what these numbers mean, and it's difficult to search since Google throws away the brackets and slash. This is generated by window_copy_write_line() in window-copy.c: if (py == 0) { size = xsnprintf(hdr, sizeof hdr, "[%u/%u]", data->oy, screen_hsize(data->backing)); if (size > screen_size_x(s)) size = screen_size_x(s); screen_write_cursormove(ctx, screen_size_x(s) - size, 0); screen_write_puts(ctx, &gc, "%s", hdr); but the variable names aren't very instructive to someone who isn't familiar with the code. Any hints as to what these numbers mean?

• Do I have a bad SD card?

  - by User1

  I'm trying to copy data from my computer to an SD card. After a few hundred megs, I keep getting the following errors in dmesg: [34542.836192] end_request: I/O error, dev mmcblk0, sector 855936 [34542.836284] FAT: unable to read inode block for updating (i_pos 13694981) [34542.836306] MMC: killing requests for dead queue [34542.836310] end_request: I/O error, dev mmcblk0, sector 9280 [34542.837035] FAT: unable to read inode block for updating (i_pos 148486) [34542.837062] MMC: killing requests for dead queue [34542.837066] end_request: I/O error, dev mmcblk0, sector 1 [34542.837074] FAT: bread failed in fat_clusters_flush [34542.837085] MMC: killing requests for dead queue These were all files I copied from a smaller SD card. I just want to transfer them to my new, larger card for my phone. I tried the same experiment with different files on a different machine and the card failed again. Reading data from the old card went fine. My systems are older and the new SD card is new (16GB Class 4). Could this be that my computers are too old? Is there a definitive test to verify if my SD card is bad?

• Migrating users and IIS settings from a workgroup win2k3 machine to a new win2k8r2

  - by amber

  I am retiring my old Windows Server 2003 Standard 32bit machine to a new machine with Windows Server 2008 R2 Standard. The two sticking points are migrating user accounts (and there are a lot of them) and IIS settings/websites (again, there are a lot). The new machine has not been provisioned yet. I'm at that point where I'm about install the OS on it. The old machibe is configured with a mirrored set for its OS and data partitions. I have broken the mirror set, replicated all of the data to an external drive, and then rebuilt the mirror set. In short, I have an image of the old machine to play with while safely leaving it up and running. Thanks!

• XP SP3 PRO - Delayed write failed $mft- can I get which particular file caused the problem ?

  - by user35020

  Hi - I sometimes get that error when resuming from hibernation : Delayed Write Failed : Windows was unable to save all the data for the file G:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. I know this is caused because the hard drive (G:, a usb external drive) which was plugged in when I hibernated was not read at the right moment - or sometimes I simply forgot to plug it when resuming from hibernation. My question is : is there any way to see which particular file/folder/folder status/don't know what failed to be written ? Hard drive functions correctly before and after - no problem. Is there a detailed log someplace or a utility ? Searched and searched but nothing. Thanks for any help !

• Move MySQL master

  - by Noodles

  I currently have a master db server (lets call it db1) and 6 slaves (slave1-6). I've setup a new server (db2) as a slave of db1 and it's in sync. I want to change all the slaves to use db2 instead of db1, but with minimal downtime/data loss. At the moment the only way I can think of doing it is shutting down our website (so data stops being written to db1), waiting until all the slaves are up to date, flush logs on db1, shut it down. Reset master on db2, change all slaves to point to db2 with log position = 0. Is this the right way to do it or is there a way to do it without taking the site offline?

• Turn off write barriers on ext4 whiche FS is mounted

  - by user462982

  I am doing some IO intensive DB imports that run for several days now and the IO performance has dropped tremendously over times. The DB data files (log files) are on an ext4 formatted logical volume which is mounted with default options (did not specify something special in fstab). Since I just learned that ext4 enables write barriers by default: Q: Is there some way to disable write barriers online (i.e. while the file system is in use), because I cannot interrupt the import and don't want to restart it again. I am aware that write barriers might not be the only thing impeding performance it is a bad idea to have write barriers disabled on journalling file systems if data safty is important (e.g. on a production system)

• Hard disk failure. Can I recover my "move"d folders?

  - by Doug

  I am in the process of moving all my files from an old laptop to new one. I just moved 11gb of data from my old laptop to a hard drive (external) and then upon moving it out to the new hard drive, the hard drive is getting a CRC (Data Error (Cyclic Redundancy Check). Now I am looking for a solution to recover the files that I moved on my old laptop (not the external). I understand they they are just marked for potential overwriting to free up space. I was getting ready to test out GetDataBack, but it says to install it on a healthy windows and use the recover-needed drive as an external. However, I don't want to turn off my computer without first getting the okay since it is in a "moved" state. Please help! What can I do to recover the Moved files. I haven't touched the computer since it has been moved. What can I use to recover them?

• Sync two external harddrives?

  - by acidzombie24

  A little mishap happened earlier today and i am thinking i should have a copy of my external harddrive since 10% of it is very valuable. What is the best solution to keep two external harddrive in sync? i'll probably use one as regular and maybe use the other only to copy data. The easiest way to keep it in sync is to clear one drive and copy the other but 1T of data will take a long time. Whats a good existing app that will keep them in sync? freeware preferred.

• Most secure way to access my home Linux server while I am on the road? Specialized solution wanted

  - by Ace Paus

  I think many people may be in my situation. I travel on business with a laptop. And I need secure access to files from the office (which in my case is my home). The short version of my question: How can I make SSH/SFTP really secure when only one person needs to connect to the server from one laptop? In this situation, what special steps would make it almost impossible for anyone else to get online access to the server? A lot more details: I use Ubuntu Linux on both my laptop (KDE) and my home/office server. Connectivity is not a problem. I can tether to my phone's connection if needed. I need access to a large number of files (around 300 GB). I don't need all of them at once, but I don't know in advance which files I might need. These files contain confidential client info and personal info such as credit card numbers, so they must be secure. Given this, I don't want store all these files on Dropbox or Amazon AWS, or similar. I couldn't justify that cost anyway (Dropbox don't even publish prices for plans above 100 GB, and security is a concern). However, I am willing to spend some money on a proper solution. A VPN service, for example, might be part of the solution? Or other commercial services? I've heard about PogoPlug, but I don't know if there is a similar service that might address my security concerns? I could copy all my files to my laptop because it has the space. But then I have to sync between my home computer and my laptop and I found in the past that I'm not very good about doing this. And if my laptop is lost or stolen, my data would be on it. The laptop drive is an SSD and encryption solutions for SSD drives are not good. Therefore, it seems best to keep all my data on my Linux file server (which is safe at home). Is that a reasonable conclusion, or is anything connected to the Internet such a risk that I should just copy the data to the laptop (and maybe replace the SSD with an HDD, which reduces battery life and performance)? I view the risks of losing a laptop to be higher. I am not an obvious hacking target online. My home broadband is cable Internet, and it seems very reliable. So I want to know the best (reasonable) way to securely access my data (from my laptop) while on the road. I only need to access it from this one computer, although I may connect from either my phone's 3G/4G or via WiFi or some client's broadband, etc. So I won't know in advance which IP address I'll have. I am leaning toward a solution based on SSH and SFTP (or similar). SSH/SFTP would provided about all the functionality I anticipate needing. I would like to use SFTP and Dolphin to browse and download files. I'll use SSH and the terminal for anything else. My Linux file server is set up with OpenSSH. I think I have SSH relatively secured. I'm using Denyhosts too. But I want to go several steps further. I want to get the chances that anyone can get into my server as close to zero as possible while still allowing me to get access from the road. I'm not a sysadmin or programmer or real "superuser". I have to spend most of my time doing other things. I've heard about "port knocking" but I have never used it and I don't know how to implement it (although I'm willing to learn). I have already read a number of articles with titles such as: Top 20 OpenSSH Server Best Security Practices 20 Linux Server Hardening Security Tips Debian Linux Stop SSH User Hacking / Cracking Attacks with DenyHosts Software more... I have not implemented every single thing I've read about. I probably can't do that. But maybe there is something even better I can do in my situation because I only need access from a single laptop. I'm just one user. My server does not need to be accessible to the general public. Given all these facts, I'm hoping I can get some suggestions here that are within my capability to implement and that leverage these facts to create a great deal better security than general purpose suggestions in the articles above.

• Reading a file from an alternate location

  - by Highstaker

  I have a certain file (data.abc) located in, say, my home folder. I make a copy of it to another location (for example, "/mnt/ramtemp/"). Whenever the file in my home folder is accessed by any process, I want it to be read not from home folder, but from "/mnt/ramtemp/". As you might have guessed from the path of the latter, it is where I mount the ramfs. So, basically, I want a process to access not the file on my HDD (which is slower), but its copy on ramfs (which is way faster). At the same time, I want the file data.abc to remain in my home folder under that name, I don't want to rename or delete it. Is there any way I could guide the system to redirect the processes to read the file from alternative location whenever they try to read it from home folder?

• What are the recognized ways to increase the size of the RAID array online/offline?

  - by user149509

  Is it possible, in theory, increase the size of the RAID-array of any level just by adding new drive(s)? Variant like "backup whole data - delete old array - add/replace disks - create new array - restore data" is obvious so what are the other options? Does it depend on the RAID-level only or on the implementation of RAID-controller only, or on both? Adding new disks to a striped array necessarily leads to a rebuilding of the array with the redistribution of the strips to the new drives? What steps should be done to increase size of RAID-array in online/offline scenarios? Especially interesting RAID-5 and RAID-10. I would like to see the big picture.

• WIndows Hosted Network

• Is it safe to set MySQL isolation to "Read Uncommitted" (dirty reads) for typical Web usage? Even with replication?

  - by Continuation

  I'm working on a website with typical CRUD web usage pattern: similar to blogs or forums where users create/update contents and other users read the content. Seems like it's OK to set the database's isolation level to "Read Uncommitted" (dirty reads) in this case. My understanding of the general drawback of "Read Uncommitted" is that a reader may read uncommitted data that will later be rollbacked. In a CRUD blog/forum usage pattern, will there ever be any rollback? And even if there is, is there any major problem with reading uncommitted data? Right now I'm not using any replication, but in the future if I want to use replication (row-based, not statement-based) will a "Read Uncommitted" isolation level prevent me from doing so? What do you think? Has anyone tried using "Read Uncommitted" on their RDBMS?

• How to explain DRM cannot work?

  - by jerryjvl

  I am looking for the shortest comprehensive way to explain to people that are trying to use DRM as a technology to prevent users from using their data in some fashion deemed undesirable, why their solution cannot work by definition. Ideally I'd like something that: Covers why technically it is impossible to have people access local data, but only in such-and-such a way Imparts an understanding of why this is, to avoid follow-on "But what if" rebuttals Is intuitive enough and short enough that even a politician (j/k) could grasp it When faced with this situation I try to be clear and concise, but I usually end up failing at least on one of these points. I'd really like to have a 'stock' answer that I can use in the future.

• Will you install software on the same partition as Windows system?

  - by Tim

  I was wondering if you always install software on the same partition as Windows 7 system? What kinds of software do you install on the same partition as Windows system? What kinds of software you install on another partition? If you install software on another partition, do you install them on a dedicated partition to these software? Or do you install them on the same partition as data (personal data)? How do you plan the sizes for the partition(s) in either case? What are to consider when making plans about the above questions? The software I am installing include: Matlab, Mathematica, IDEs, compilers or Interpreters for C++, C, Java, R, Python, Perl, Lisp, Latex, and database. Mainly for programming and typesetting kinds of studies and projects.

• Why do I see different TCP behaviour between IIS and FTP server applications on Windows 2003?

  - by rupello

  I am comparing Wireshark traces of a 10MB file download file from: the FileZilla FTP server and IIS (using HTTP) on the same Windows 2003 server. The FTP download performs faster and the trace shows the server behaving as expected, sending more data to the client with every ACK received: Link to full-size image The HTTP server trace shows a more bursty pattern. The timing of the send bursts are sometimes unrelated to any ACKs received from the client (circled in red): Link to full-size image Anyone have a suggestion as to why IIS traffic is having like this? Update: We have tried modifying the http.sys registry settings (setting MaxBytesPerSend to 256k and MaxBufferedSendBytes to 64k as recommended). Changing MaxBytesPerSend does seem to improve performance by increasing the amount of in-flight data , but we still see the same bursty pattern.

• Allow PHP to write file without 777

  - by camerongray

  I am setting up a simple website on webspace provided by my university. I do not have database access so I am storing all the data in a flat file. The issue I am experiencing is related to file permissions. I need PHP to be able to read and write the data file but I don't really want to set the file to 777 as anybody else on the system could modify it, they already have read access to everyone's web directories. Does anyone have any ideas on how to accomplish this? Thanks in advance

  Hi everyone Im looking for an app pr line of code that could let me observe a process, save the info in a number of variable and then put the gathered info on a file. Ive been trying with variations of top but no luck. I am running several CentOS virtual servers, VM is 2gb ram 2 processor. Maybe a script that works over a specified amount of time while writing lines with the info on a text file so at the end i can have a sort of table with the data.

• Filename Case issue with over WebDav

  We are accessing SAMBA shared directory from a Windows Client with WebDav client WebDrive. But we are having the issue that it is showing same contents in both the directories ( data/ & Data/ ) though they are entirely different. I know this is because of Windows Filesystem being case insensitive and Linux being Case Sensitive. is there any solution for this? We had the same issue when viewed through the SAMBA mounted directory but we solved it by editing the SMB.conf as said in the following link Does Samba work well with Windows when case-sensitive names are enabled? Please help to solve this when accessed from the WebDav

• FreeNAS 8 and ext fs

  - by oraclecow

  i'm trying out freenas8 for my personal NAS, i have lots of data that was in an ubuntu server, but somehow i never got the file sharing right. on freenas things just worked. i installed on usb, tried sharing the windows disk, and i can see it on my windows 7 right away. my question is, is it ok to use ext4 fs from my ubuntu instalation ? i only saw zfs, ufs, ntfs, and ext2 option to import, i havent plugged in the disks yet, but im wondering the consequences, like if it asked to format like in windows to use. i can format the disks of course, but 5-6 TB of data juggling and reformatting is a lot of work, unnecessary work i think, does the zfs worth the trouble of formatting everything ? since i'm thinking to use it if i have to format it anyway and zfs looks more interesting than ext2.

• How to lookup a value in a table with multiple criteria

  - by php-b-grader

  I have a data sheet with multiple values in multiple columns. I have a qty and a current price which when multiplied out gives me the current revenue (CurRev). I want to use this lookup table to give me the new revenue (NewRev) from the new price but can't figure out how to do multiple ifs in a lookup. What I want is to build a new column that checks the "Product", "Tier" and "Location/State" and gives me the new price from the lookup table (above) and then multiply that by the qty. e.g. Data > Product, Tier, Location, Qty, CurRev, NewRev > Product1, Tier1, VIC, 2, $1000.00, $6000 (2 x $3000) > Product2, Tier3, NSW, 1, $100.00, $200 (1 x $200) > Product1, Tier3, SA, 5, $250.00, $750 (5 x $150) > Product3, Tier1, ACT, 5, $100.00, $500(5 x $100) > Product2, Tier3, QLD, 2, $150.00, $240 (2 x $240) Worst case, if I just get the new rate I can create another column

• One huge drive (network share) from many computers, with folder priority redundancy.

  - by Exception Duck

  Not sure if this exists, but I have a huge amount of data to store (about 5-50mb files) and as it is now, I have 5 computers, each with raid 5 providing about 6TB hard drive each. This is causing some problems with the software I am using (something home made) so I'm wondering, is there some software that I can install on all those computers that will mask it as one huge drive... Running windows on those computers, from Xp 64 bit to windows server 2008 I would also like to set a priority on each folder on the redundancy it has, some folders I can live without no online backup (I have a backup in a safe of that data) but some I need full online backup system if one hard drive fails. Something open source, as I try to use that as much as I can, but all ideas welcome.

• Debian: Give users permission

  - by 50ndr33

  I have a www-data that was automatically set up when I installed Apache. I have a ftpuser that I configured myself to use with ProFTPd. I use a MySQL database with users that use this user to log on. The problem is that Apache with PHP is working as it should, but I cannot add files with FTP. I tried to do chmod 777 mysite.com, and it worked, but now Apache gave me a 500 internal error. I suppose chmod isn't the correct way to go. I deleted my folder and made a new one. How can I give ftpuser permissions to read and write, while www-data should not loose its permissions. I don't have much experience with Linux command line. Thanks!
