  • Why can I not edit, delete directories inside of this directory

    - by user43053
    Hello there, First, I thought this was PHP related, but maybe it isn't. My original post, which may be irrelevant now is located at the bottom. The problem is I have a directory : /articles/. In it are 10 sub directories. I have been changing the permissions lately, but now it seems all the permissions of the parent folder, sub-folders and files are either chmod 755 or 777. I cannot move, delete or edit files inside of this parent directory or sub-directories with my FTP-client. I can however edit, delete, create new files and directories and change them with PHP-functions without problems. What may the problem be? OLD POST. Ignore everything below this line: If I create a directory with mkdir(), or create a file with fopen(), file_put_contents() or SimpleXMLElement::asXML(), I am unable to access the file with my FTP-client or c-Panel File Manager. If I try to delete or edit them, I get errors. Dreamweaver suggests it is a permission problem or a network or filesystem fault (but I've set the permissions with chmod() to 0777, and when I check the cPanel, it confirms chmod 777. I also tried to use fileowner() and the function returns int(99), the same owner as those files that I could access with my FTP-client. It seems files and directories created with PHP can only be modified or be deleted with PHP. I thought this must be a server setup related issue, so I write it here. I am on a shared server, and I have no idea about setting up servers. EDIT: It seems the problem is different. I cannot move files with FTP-client to the parent, or sub-directories either. This problem may not be PHP related, then. It seems the problem applies to any directory, regardless of whether it was created by PHP. EDIT 2: The parent directory has chmod 755. Thank you for your time. Kind regards Marius

  • Microsoft Word 2008 on the Mac sometimes "Disappears" documents, really.

    - by Ross Charette
    This happens in a computer lab environment, has happened at least 3 times. We are running Microsoft Office 2008 for mac on Leopard, everything is updated. Our user's home directories are on a network drive, but the /Library/Cache folder is running locally. Typically a student will have a Word file that they have been working on, it's been saved before they even logged onto the computer that day. They log on, open the document, click the save icon (not go to File Save), sometimes even save multiple times, then close Word. The document is now gone. It's not hidden, there are no autosaves or anything in the Cache folder. Definitely not in the trash or trashes folder. It can't find it when you click on it in 'recent documents'. Searching meticulously though every folder in their home drive turns up nothing. They look using Finder, I look ssh'd as root into their home using ls -la. I look for similar files in case they renamed it by mistake. It's gone. Disappeared. Vaporized. It's happened to at least 3 different users in the past year. Much whining. Any idea?

  • Monitor torrent user in network [closed]

    - by Usman
    I am using active directory in windows server 2008 R2 having IP address is 10.10.10.10 and my DSL modem Ip is 10.10.10.101. All clients are using 10.10.10.101 default gw to access the Internet. I don't know who is using Torrent in network or downloading something via IDM or something else. I just want to Monitor my clients for who are download via torrent or whatever. Is there anything in Windows Server 2008r2 that would allow me to do this monitoring, or do I need something else?

  • Win7 loses connection to network shares after resume unless server specified using FQDN

    - by Szonja Zemkó
    My Win7 client has a connection to a Linux server and its shared folders. The problem occurs when the computer wakes up after a sleep and then one of the shared folders is not accessible. I receive the following message: Error code: 80070035, The network path was not found. I have problem with one specific folder only. When I restart the computer this problematic folder is accessible again. When I log off before sleep the folder is accessible after wakeup. If I try to access the folder by using the FQDN of the server or the server IP it is also accessible. As a temporary solution I mapped the folder to a network drive using the FQDN and it's working fine but it's inconvenient since every other folder is accessible on the server. To summarize: \server\problematicshare no longer works after resume (the Samba server sees my client connect, then disconnects a few seconds later while I receive the above error message) \server\othershare works after resume \fqdn.of.server\problematicshare always works \ip.of.server\problematicshare always works once the problem manifests, I'm no longer able to restart the "Workstation" service (it is not responding) restarting the "Computer Browser" service has no apparent effect the event log doesn't contain anything that seems relevant "ping server" works

  • Cannot connect to a shared network drive

    - by dublintech
    I am using windows 7, I cannot connect to a shared network drive on another machine. I can ping the machine. I can remote desktop connect to the machine. The machine is on the same subnet My friend with the exact same laptop as me (and on the same network, same workgroup) can connect to the shared folder. The machine I am trying to connect to and my friends machine can both see shared folders on my machine. I also cannot see shared folders on the friends laptop. When I select diagnose, windows tells me nothing useful. When I select see details on the error pop up, I see: Error code: 0x80004005 (google doesn't help much) I can nbtstat -a the machine who has the shared folder. When I try with my firewall turned off the same happens. I have ensured my windows 7 has all updates. I run security essentials to ensure my laptop is clean. I run ccleaner to clean up my registry. Same error. I have tried with my laptop on both wireless and ethernet. As you can imagine, I am banging my head against the wall on this one.

  • I have just created a subnet for a local network, connecting to a standalone server on another network, now I cannot connect to the internet

    - by Seth
    I am just learning some new aspects of servers and networking. We have a network of 5 subnets that all interconnect with each-other. In order to get two computers on the subnet that we were setting up, I changed the IP from the subnet where the standalone server is on (where they used to be set up)to the local subnet we are remotely hooking up. Likewise I also changed the gateway to coincide with the new subnet. Only problem is that since doing this, I am unable to establish a connection to the internet. I can ping the server and correspong gateway & DNS server, but cannot get connected to the internet. We do have a dumb-switch (non-programmable) connected that receives both the internet and private network inputs and distributes (or should do so) to about 5 other computers. Bottom line, I cannot currently connect to the internet, and am wondering what could be causing this.. It is likely something very obvious and pardon me being more vague than I probably should be, but I could use some help resolving this! Thanks for any help!

  • Query total page count via SNMP HP Laserjet

    - by Tim
    I was asked to get hold of the total pages counts for the 100+ printers we have at work. All of them are HP Laser or Business Jets of some description and the vast majority are connected via some form of HP JetDirect network card/switch. After many hours of typing in IP addresses and copying and pasting the relevant figure in to Excel I have now been asked to do this on a weekly basis. This led me to think there must be an easier way, as an IT professional I can surely work out some time saving method to solve this issue. Suffice it to say I do not feel very professional now after a day or so of trying to make SNMP work for me! From what I understand the first thing is to enable SNMP on the printer. Done. Next I would need something to query the SNMP bit. I decided to go open source and free and someone here recommended net-snmp as a decent tool (I would like to have just added the printers as nodes in SolarWinds but we are somewhat tight on licences apparently). Next I need the name of the MIB. For this I believe the HP-LASERJET-COMMON-MIB has the correct information in it. Downloaded this and added to net-snmp. Now I need the OID which I believe after much scouring is printed-media-simplex-count (we have no duplex printers, that we are interested in at least). Running the following command yields the following demoralising output: snmpget -v 2c -c public 10.168.5.1 HP-LASERJET-COMMON-MIB:.1.3.6.1.2.1.1.16.1.1.1 (the OID was derived from running: snmptranslate -IR -On printed-media-simplex-count Unlinked OID in HP-LASERJET-COMMON-MIB: hp ::= { enterprises 11 } Undefined identifier: enterprises near line 3 of C:/usr/share/snmp/mibs/HP-LASER JET-COMMON-MIB..txt .1.3.6.1.2.1.1.16.1.1.1 ) Unlinked OID in HP-LASERJET-COMMON-MIB: hp ::= { enterprises 11 } Undefined identifier: enterprises near line 3 of C:/usr/share/snmp/mibs/HP-LASER JET-COMMON-MIB..txt HP-LASERJET-COMMON-MIB:.1.3.6.1.2.1.1.16.1.1.1: Am I barking up the wrong tree completely with this? My aim was to script it all to output to a file for all the IP addresses of the printers and then plonk that in Excel for my lords and masters to digest at their leisure. I have a feeling I am using either the wrong MIB or the wrong OID from said MIB (or both). Does anyone have any pointers on this for me? Or should I give up and go back to navigationg each printers web page individually (hoping not).

  • Lock ups, crashing, transferring files using TrueCrypt with iSCSI

    - by Anthony
    I have looked into this error and it seems that it hasn't been discussed yet - or at least I can't find any information relating. I'm having issues transferring files, usually larger files over a couple of hundred MB. Here is the setup: QNAP 410 as iSCSI Target with multiple LUNs. (CRC is turned on (Data Digest and Header Digest) Server 2003 with iSCSI Initiator version 2.08 - build 3825 (I'm copying files from anothe machine to shares on Server 2003 = into TrueCrypt volume ergo onto the NAS) I have mounted the LUN and formatted it with TrueCrypt using NTFS (Full format, not a quick one). What happens is some files, mainly RAR/Compressed files, appear as if they copy but fail. I've tested this in a number of ways and can repeat the process every time. So I thought to check transfer over iSCSI without TrueCrypt in between, a plain NTFS format - no problem at all. So it would seem TrueCrypt is at least part of the problem here. I haven't tried copying directly from the server yet, I will try that. I also haven't tried it without CRC but fail to see how that would affect this. I will update with my findings later. In the meantime does anyone have any ideas as to what could be wrong? Thanks for your time. Update: I copied a set of files, the ones I was having issues with, to the server then from there I copied those into two places within the TrueCrypt volume (Mounted on the NAS). A seperate directory create in the root of the volume The same initial directory I was using in the first instance Both worked fine. So it now seems clear that this is a link between TrueCrypt, iSCSI and Windows Shares. I say this because I originally setup the whole system using TrueCrypt volume files, not iSCSI. I changed it as it didn't suit my requirements - day wasted as well. While I had this setup though I copied my entire file set to the volume files and all files copied without error - over the network, from a pc, to the server where TrueCrypt had the volume files mounted from the NAS. I didn't bother turning off CRC on the iSCSI system as I highly doubt that is the cause in light of this finding. So any ideas?

  • XP shared folders not accessible after BIOS changed

    - by stijn
    Here's what worked for over a year: PC A runs Windows 7, PC B runs Windows XP. Both are on the same subnet behind a router. A uses user account X, but logs in to PC B using the Administrator account. PC B is a Dell Precision 470. A known problem with these is that sometimes when plugging in their power cable they somehow loses all BIOS settings. This happened yesterday. After this happens Windows won't boot, because the default BIOS setting is 'RAID ON' while there is no RAID configured. No problem though, changing the BIOS settings to 'RAID OFF' makes it boot without problems. Note that in the meantime, nothing config-related was changed on machine A. It wasn't even on. Indeed after doing this, everything is fine. Everything includes all normal operations, remote desktop from PC A to PC B, running Synergy between A and B, accessing shared folders from B to A. But accessing the shared folders on B from A does not work any more. I tried pretty much everything I found via Google (fiddling with policies/registry kes/...) but no avail. > ping -a 192.168.2.2 Pinging A [192.168.2.2] with 32 bytes of data: Reply from 192.168.2.2: bytes=32 time<1ms TTL=128 > net view \\192.168.2.2 System error 5 has occurred. Access is denied. > net use /persistent:no K: \\A\myshare /user:A\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:192.168.2.2\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:USERNAME PASSWORD System error 86 has occurred. The specified network password is not correct. A solution to this would be great: I haven't been able to do any work since yesterday ;] update after taking the hard drive out of B and putting it in another Precision 470 with almost exactly the same hardware (at first sight, only the video card differs) the shared folders work.. Putting the disk back into A, same problem remains. Why does this depend on hardware, and more important, on which hardware?

  • Is there a Distributed SAN/Storage System out there?

    - by Joel Coel
    Like many other places, we ask our users not to save files to their local machines. Instead, we encourage that they be put on a file server so that others (with appropriate permissions) can use them and that the files are backed up properly. The result of this is that most users have large hard drives that are sitting mainly empty. It's 2010 now. Surely there is a system out there that lets you turn that empty space into a virtual SAN or document library? What I envision is a client program that is pushed out to users' PCs that coordinates with a central server. The server looks to users just like a normal file server, but instead of keeping entire file contents it merely keeps a record of where those files can be found among various user PCs. It then coordinates with the right clients to serve up file requests. The client software would be able to respond to such requests directly, as well as be smart enough to cache recent files locally. For redundancy the server could make sure files are copied to multiple PCs, perhaps allowing you to define groups in different locations so that an instance of the entire repository lives in each group to protect against a disaster in one building taking down everything else. Obviously you wouldn't point your database server here, but for simpler things I see several advantages: Files can often be transferred from a nearer machine. Disk space grows automatically as your company does. Should ultimately be cheaper, as you don't need to keep a separate set of disks I can see a few downsides as well: Occasional degradation of user pc performance, if the machine has to serve or accept a large file transfer during a busy period. Writes have to be propogated around the network several times (though I suspect this isn't really much of a problem, as reading happens in most places more than writing) Still need a way to send a complete copy of the data offsite occasionally, and this would make it very hard to do differentials Think of this like a cloud storage system that lives entirely within your corporate LAN and makes use of your existing user equipment. Our old main file server is due for retirement in about 2 years, and I'm looking into replacing it with a small SAN. I'm thinking something like this would be a better fit. As a school, we have a couple computer labs I can leave running that would be perfect for adding a little extra redundancy to the system. Unfortunately, the closest thing I can find is Dienst, and it's just a paper that dates back to 1994. Am I just using the wrong buzzwords in my searches, or does this really not exist? If not, is there a big downside that I'm missing?

  • How to use AD/GPO/Print Services to "push out" a new printer driver to replace a broken one? How did my server get a broken driver?

    - by Zac B
    Context: We have an AD/GPO-managed corporate network with a little over a hundred PCs running Windows 7 x64, and a few managed printers. Our Server2008R2 primary domain controller is configured as a print server for them all. Problem: After a recent windows update and restart (no printer driver updates were included) on the DC, a particular shared printer (Lexmark T650) has begin exhibiting some strange behavior. First, it prints a preceding and following blank page for almost every document, on jobs submitted by about half of client machines (no separator page is configured on the server or any of the clients I've seen). Second, whenever someone tries to access "Printing Preferences" on any client, they recieve the following error message (this happens everywhere, 100% of the time, and didn't happen before the update on the DC): Once they click "OK", the prefs screen appears (with no separator page selected) and everything seems fine. I'm not even sure if these two issues are related, but everyone seems affected by one or both of those issues. What I've Tried: I've been hesitant to un-deploy the problem printer, or remove it via GPO, as it's pretty heavily used. I've tried updating (via MS update and our internal WSUS server) client machines and the DC. No printer driver updates have appeared, and no number of updates or restarts on the server or the client seems to have achieved anything other than my boss getting grumpy that I'm bouncing the domain controller so often. I've tried deleting the drivers on the server, and re-installing them from the original source that has worked for the past year...no change. I've tried selecting "New Driver" for one of the shared printers on a client machine, running as domain admin, and pushed the latest driver found by MSupdate back up to the DC. This changed the version number of the driver recorded in the print server manager, but caused no change--on the client I pushed from, or on any other. The error still appears. Question: Why the heck is this happening? Obviously, I got a bad driver from somewhere, but how do I get rid of it? I don't know of any "roll back drivers" functionality for centrally managed print drivers like Windows offers for other devices. How would I a) get this issue resolved on a client, and b) push the fix to the other members of the domain?

  • After 10 Years, MySQL Still the Right Choice for ScienceLogic's "Best Network Monitoring System on the Planet"

    - by Rebecca Hansen
    ScienceLogic has a pretty fantastic network monitoring appliance.  So good in fact that InfoWorld gave it their "2013 Best Network Monitoring System on the Planet" award.  Inside their "ultraflexible, ultrascalable, carrier-grade" enterprise appliance, ScienceLogic relies on MySQL and has since their start in 2003.  Check out some of the things they've been able to do with MySQL and their reasons for continuing to use MySQL in these highlights from our new MySQL ScienceLogic case study. Science Logic's larger customers use their appliance to monitor and manage  20,000+ devices, each of which generates a steady stream of data and a workload that is 85% write. On a large system, the MySQL database: Averages 8,000 queries every second or about 1 billion queries a day Can reach 175,000 tables and up to 20 million rows in a single table Is 2 terabytes on average and up to 6 terabytes "We told our customers they could add more and more devices. With MySQL, we haven't had any problems. When our customers have problems, we get calls. Not getting calls is a huge benefit." Matt Luebke, ScienceLogic Chief Software Architect.? ScienceLogic was approached by a number of Big Data / NoSQL vendors, but decided against using a NoSQL-only solution. Said Matt, "There are times when you really need SQL. NoSQL can't show me the top 10 users of CPU, or show me the bottom ten consumer of hard disk. That's why we weren't interested in changing and why we are very interested in MySQL 5.6. It's great that it can do relational and key-value using memcached." The ScienceLogic team is very cautious about putting only very stable technology into their product, and according to Matt, MySQL has been very stable: "We've been using MySQL for 10 years and we have never had any reliability problems. Ever." ScienceLogic now uses SSDs for their write-intensive appliance and that change alone has helped them achieve a 5x performance increase.

  • Boosting my GA with Neural Networks and/or Reinforcement Learning

    - by AlexT
    As I have mentioned in previous questions I am writing a maze solving application to help me learn about more theoretical CS subjects, after some trouble I've got a Genetic Algorithm working that can evolve a set of rules (handled by boolean values) in order to find a good solution through a maze. That being said, the GA alone is okay, but I'd like to beef it up with a Neural Network, even though I have no real working knowledge of Neural Networks (no formal theoretical CS education). After doing a bit of reading on the subject I found that a Neural Network could be used to train a genome in order to improve results. Let's say I have a genome (group of genes), such as 1 0 0 1 0 1 0 1 0 1 1 1 0 0... How could I use a Neural Network (I'm assuming MLP?) to train and improve my genome? In addition to this as I know nothing about Neural Networks I've been looking into implementing some form of Reinforcement Learning, using my maze matrix (2 dimensional array), although I'm a bit stuck on what the following algorithm wants from me: (from http://people.revoledu.com/kardi/tutorial/ReinforcementLearning/Q-Learning-Algorithm.htm) 1. Set parameter , and environment reward matrix R 2. Initialize matrix Q as zero matrix 3. For each episode: * Select random initial state * Do while not reach goal state o Select one among all possible actions for the current state o Using this possible action, consider to go to the next state o Get maximum Q value of this next state based on all possible actions o Compute o Set the next state as the current state End Do End For The big problem for me is implementing a reward matrix R and what a Q matrix exactly is, and getting the Q value. I use a multi-dimensional array for my maze and enum states for every move. How would this be used in a Q-Learning algorithm? If someone could help out by explaining what I would need to do to implement the following, preferably in Java although C# would be nice too, possibly with some source code examples it'd be appreciated.

  • How can i monitor syslog messages in c# console app with TCP

    - by djerry
    Heya, In my application, i need to monitor all messages sent by syslog. I've tried with UDP, but after one message, i didn't respond anymore (no error, just no heads up anymore). And setting up a tcp server isn't really the solution either i think. Can anyone guide me to a solution where i can log messages form syslog with tcp (normally on port 514). Thanks in advance.

  • Best tools to monitor Tomcat

    - by Pier Luigi
    Hi all, I'm searching free tools for monitor tomcat (traffic, memory usage, threads, requests, CPU, logs,...). I'm currently using lambdaprobe on Tomcat 5.5.x, but it seems that is no more developed (or not? the site lambdaprobe.org is always down for me...). Has someone good experiences to share? In lambdaprobe there are some info available only if tomcat is instrumented with JMX. Well, JMX is something of strange and mysterious for me. Is a good solution in a production server? It's worth to spend my (little) time to learn it?

  • How to know about MySQL 'refused connections'

    - by celalo
    Hello, I am using MONyog to montitor my two mysql servers. I get alert emails from MONyog when something goes wrong. There is an error I could not find out why. It says: Connection History: Percentage of refused connections) - 66.67% the percentage is not important, this is just about having refused connections. I get this email every half an hour. So this is like a constant situation. This must be my mistake, because I just set up those servers and there is no chance somebody else could be interfering the servers. MONyog advices me: Try to isolate users/applications that are using an incorrect password or trying to connect from unauthorized hosts. A client will be disallowed to connect if it takes more than connect_timeout seconds to connect. Set the value of log_warnings system variable to 2. This will force the MySQL server to log further information about the error. I added log_warnings=2 to my.cnf and I enabled logging like this: [mysqld_safe] . . log_warnings=2 log-error = /var/log/mysql/error.log . . . . [mysqld_safe] . log-error=/var/log/mysqld.log . . I cannot see any warnings at /var/log/mysql/error.log I can see some warnings at /var/log/mysqld.log but they are about something else. In sum, my question is how can I detect refused connections? Please let me know if any more info is required. Thanks in advance.

  • theoretical and practical matrix multiplication FLOP

    - by mjr
    I wrote traditional matrix multiplication in c++ and tried to measure and compare its theoretical and practical FLOP. As I know inner loop of MM has 2 operation therefore simple MM theoretical Flops is 2*n*n*n (2n^3) but in practice I get something like 4n^3 + number of operation which is 2 i.e. 6n^3 also if I just try to add up only one array a[i][j]++ practical flops then calculate like 3n^3 and not n^3 as you see again it is 2n^3 +1 operation and not 1 operation * n^3 . This is in case if I use 1D array in three nested loops as Matrix multiplication and compare flop, practical flop is the same (near) the theoretical flop and depend exactly as the number of operation in inner loop.I could not find the reason for this behaviour. what is the reason in both case? I know that theoretical flop is not the same as practical one because of some operations like load etc. system specification: Intel core2duo E4500 3700g memory L2 cache 2M x64 fedora 17 sample results: Matrix matrix multiplication 512*512 Real_time: 1.718368 Proc_time: 1.227672 Total flpops: 807,107,072 MFLOPS: 657.429016 Real_time: 3.608078 Proc_time: 3.042272 Total flpops: 807,024,448 MFLOPS: 265.270355 theoretical flop: 2*512*512*512=268,435,456 Practical flops= 6*512^3 =807,107,072 Using 1 dimensional array float d[size][size]:512 or any size for (int j = 0; j < size; ++j) { for (int k = 0; k < size; ++k) { d[k]=d[k]+e[k]+f[k]+g[k]+r; } } Real_time: 0.002288 Proc_time: 0.002260 Total flpops: 1,048,578 MFLOPS: 464.027161 theroretical flop: *4n^2=4*512^2=1,048,576* practical flop : 4n^2+overhead (other operation?)=1,048,578 3 loop version: Real_time: 1.282257 Proc_time: 1.155990 Total flpops: 536,872,000 MFLOPS: 464.426117 theoretical flop:4n^3 = 536,870,912 practical flop: *4n^3=4*512^3+overheads(other operation?)=536,872,000* thank you

    Does anyone know of an app that can monitor a beanstalkd queue? I'm looking for something that shows stats on tubes and jobs, and allows you to inspect the details. I'm not really picky about language/platform, just want to know if there's something out there before I write my own.

  • Is there a way in .NET to access the bytecode/IL/CLR that is currently running?

    - by Alix
    Hi. I'd like to have access to the bytecode that is currently running or about to run in order to detect certain instructions and take specific actions (depending the instructions). In short, I'd like to monitor the bytecode in order to add safety control. Is this possible? I know there are some AOP frameworks that notify you of specific events, like an access to a field or the invocation of a method, but I'd like to skip that extra layer and just look at all the bytecode myself, throughout the entire execution of the application. I've already looked at the following questions (...among many many others ;) ):     Preprocessing C# - Detecting Methods     What CLR/.NET bytecode tools exist? as well as several AOP frameworks (although not in great detail, since they don't seem to do quite what I need) and I'm familiar with Mono.Cecil. I appreciate alternative suggestions, but I don't want to introduce the overhead of an AOP framework when what I actually need is access to the bytecode, without all the stuff they add on top to make it more user-friendly (... admittedly very useful stuff when you don't want to go low-level). Thanks :)
