• ubuntu server slowly filling up

  - by Crash893

  We had our samba server (ubuntu 8.04 ltr) share fill up the other day but when I went to look at it I cant see any of the shares have to much on them we have 5 group shares and then each users has an individual share one users has 22gigs of stuff a few others have 10-20mb of stuff and everyone else is empty so maybe like 26gigs total I deleted a few files yesterday and freed up about 250mb of space today when i checked it it was completely full again and i deleted some older files and freed up about 170mb of stuff but i can watch it slowly creep down in free space. I keep running a df -h Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 241690180 229340500 169200 100% / varrun 257632 260 257372 1% /var/run varlock 257632 0 257632 0% /var/lock udev 257632 72 257560 1% /dev devshm 257632 52 257580 1% /dev/shm lrm 257632 40000 217632 16% /lib/modules/2.6.24-28-generic /volatile what can I do to try to hunt down whats taking up so much of my hdd?

• How to get gigabit network speeds on Windows XP?

  - by JB

  We've just installed gigabit switches at work, and things on the Linux side are going well. Our linux boxes, which use a Intel Corporation 82566DM-2 Gigabit nic (according to lspci), consistently get over 900 mbits/sec: iperf -c ipserver ------------------------------------------------------------ Client connecting to ipserver, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.40.9 port 39823 connected with 192.168.1.115 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 1.08 GBytes 929 Mbits/sec We have a bunch of Windows XP 64-bit machines that use Broadcom NetXtreme 57xx cards. I spent around a day trying to get equivalent speeds on them, but couldn't get above 200 Mbits/sec. I noticed the Windows iperf tests said that the TCP window size was 8 Kb by default (as opposed to 16 Kb on Linux, so I modified my test to reflect that. Still no love. I went to Broadcom's site, downloaded the latest drivers for the card and installed. Still no love. However, finally, I tried a 64 Kb window size with the new drivers, and finally an improvement! $ iperf -c ipserver -w64k ------------------------------------------------------------ Client connecting to ipserver, TCP port 5001 TCP window size: 64.0 KByte ------------------------------------------------------------ [ 3] local 192.168.40.214 port 1848 connected with 192.168.1.115 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 933 MBytes 782 Mbits/sec Much better, but still not really taking advantage of the full capabilities of the network. If the Linux box can reach 950 Mbits/sec consistently, this box should be able to as well. Also, if you're wondering about the medium, this is over the same cable...I'm switching back and forth. Any suggestion or ideas would be really welcome. Thanks!

• How do you cache web pages with a personalized header using caching reverse proxy such as Squid, Var

  - by Continuation

  Pretty much every page of my website is dynamically generated. However they don't change that frequently (kinda similar to a forum page). So I'd like to cache them using a caching reverse proxy such as Squid, varnish or Nginx. The problem is that for my logged-in users, each of them will see a personalized header saying "Welcome John Doe. Logout" on the upper right corner of the page (just like serverfault). While users who aren't logged in will see a header that says "Login" instead. So basically even though every user will see the same page in general, they all slightly different version due to that personalized header. Is there any way so that I can cache the "main" part of the page and serve it from cache while generate the personalized header dynamically for each individual user? This must be a very common problem. How is it solved in general?

• Maintenance Plan Reporting - Append To File - Clean Up?

  - by Adam J.R. Erickson

  Background: (SQL Server 2005, Standard Ed.) I have a maintenance plan running backups, taking a full backup 1/day, and t-log every 15 minutes. I have it set to create a text file report of each run, but that creates A LOT of files on the file server. These are hard to sort through, which makes them less useful. Question: There is an option in "Reporting and Logging" settings for appending all logs together, but how do you clean this out? If you're appending to the same log file every time, how should you make sure this file doesn't grow indefinitely? Is there a build-in function to clean out portions of appended logs like there is for cleaning out individual old log files?

• Nagios3 gives a warning on HTTP service monitoring

  - by Dez

  Already set up my local net configuration to be monitored by Nagios3. I found a problem that Nagios3 reports a warning in the HTTP monitoring service of a Debian server set at ip 192.168.1.52, that has an individual virtual host and a mass virtual host for application development. I get this status message: HTTP WARNING: HTTP/1.1 404 Not Found I used the Nagios tools to check. servername is the name of the vhost server name I used in the Apache configuration. /usr/lib/nagios/plugins/check_http -H servername -I 192.168.1.52 receiving this status message: HTTP OK HTTP/1.1 200 OK - 37900 bytes in 0.504 seconds |time=0.503946s;;;0.000000 size=37900B;;;0 But when I check like this: /usr/lib/nagios/plugins/check_http -I 192.168.1.52 I get the same status message as the warning, so I assume that I don't have Nagios completely well set up because doesn't recognize the vhosts for that server, how it should be as the check_http service shows. Where should I look to fix that warning?

• SQL Server: Is it possible to prevent SQL Agent from failing a step on error?

  - by franklinkj

  I have a stored procedure that runs custom backups for around 60 SQL servers (mixes 2000 through 2008R2). Occasionally, due to issues outside of my control (backup device inaccessible, network error, etc.) an individual backup on one or two databases will fail. This causes this entire step to fail, which means any subsequent backup commands are not executed and half of the databases on a given server may not be backed up. On the 2005+ boxes I am using TRY/CATCH blocks to manage these problems and continue backing up the remaining databases. On a 2000 server however, for example, I have no way to prevent this error from failing the entire step: Msg 3201, Level 16, State 1, Line 1 Cannot open backup device 'db-diff(\PATH\DB-DIFF-03-16-2010.DIF)'. Operating system error 5(Access is denied.). Msg 3013, Level 16, State 1, Line 1 BACKUP DATABASE is terminating abnormally. I am simply asking if anything like this is possible in SQL 2000 or if I need to go in a completely different direction.

• Remotely managing Hyper-V VMs from Windows 8 Client

  - by Vazgen

  Currently, I have a core Hyper-V Server hosting VMs for a domain controller and several domain-joined VDI infrastructure servers. The VMs are connected in that domain environment, but the remote management of the physical Hyper-V Server is set up using the same WORKGROUP (as the Windows 8 client I'm managing from) This makes it cumbersome to manage the VMs hosted on the physical server from my remote management Windows 8 client because I can only connect to the physical Hyper-V server and not the individual VMs hosted inside. Can I make my set up more flexible by hosting a second domain controller in a VM hosted on my Windows 8 machine and switching my remote management set up to use the same domain through? Meaning ALL physical and virtual machines including the VDI infrastructure under the same domain? I'm new to this just looking for some suggestions.

• Get cryptic error when trying to create a snapshot of any of my VMs

  - by Zolt

  I'm using Oracle VM VirtualBox. I have 6 VMs that I've imported. When I click on an individual VM, and then click the camera image (or Ctrl+Shift+S) to take a snapshot, the snapshot process fails and VirtualBox gives the following error: Failed to create a snapshot of the virtual machine vmName. Details: Result Code: VBOX_E_IPRT_ERROR (0x80BB0005) This happens not only for one of my VMs, but all of them, if I try to take a snapshot of each one separately, one at a time. My computer is a Windows 7 machine. I have 200 GB free on my hard drive, and I see no reason why the error should occur. I can import VMs, run them, and clone then without any problems. Can anyone tell me what to do to fix the issue?

• Unix copy command that has a progress bar, but not as heavy as rsync

  - by Rory McCann

  I need to copy lots of files. Usually I use rsync because I pass it the -aP options and I can see (a) how many files are left to process and (b) how much of each individual file is copied. However rsync also does lots of things with checksums to verify that a file was copied. However I don't really need that now. But normal cp doesn't include the above mentioned count of files left, which is very helpful. Is there anything like cp that includes progress of how many files left, but isn't as heavy as rsync?

• Universal Windows XP With Ghost and Sysprep

  - by RobertPitt

  Hey I have an idea but im not sure whether it is possible and looking for advice on how to accomplish this. If i was to try and deploy Windows XP Sysprepped image from a Lenovo Thinkcentre 6073-CTO and tried to drop it onto a Dell Optiplex for instance I would get a BSOD due to the hardware change. What im looking to do is create a few images like so: Windows XP x86 SP3 (Sysprepped) Windows XP x64 SP3 (Sysprepped) ... So that we can use throughout the organization without having to create individual images per computer type. Is there anyway's to accomplish this such as some modification of files pre-ghost, removal a certain drivers pre-sysprep Any advice is appreciated.

• How to maintain one file across many production servers (Windows and Linux)

  - by Brien

  My organization wants to centrally manage an Oracle TNSnames file for all of their production servers. When that file changes, they want to be able to push out the changes to all servers that use it with a minimal effort. Approaches that have been considered: Centralized file server (drawback: if the file server or the network connection to the file server goes down, the servers have no access to the critical file) Subversion client on each server (drawback: using a source control tool in production, added complexity) Store an individual copy of the file on each server (drawback: changing the file contents involves making changes on many different servers) Update Can I use DFS to do this?

• How to clear stuck locked maildrop pop3 process

  - by Joshua

  I am using cyrus for imap and pop One of my users is getting the following error: Unable to lock maildrop : Mailbox is locked by POP server. I can see where it starts in the log. I've read that there is no physical lock file anymore (i've tried looking for it anyways) and that the solution is to just wait for the timeout, or kill the offending pop3 process. I know that this is happening because of a lossy connection on the part of the affected user, and that pop3 can only have 1 session active at a time. I need to manually clear the lock and I am having trouble finding the offending pop process. I have tried lsof, but it doesn't say how long the individual files (sockets) have been opened for. I've reduced the tcp keepalive time down to 5 mins, but I still need to reset this guy's lock. I could use some pointers. Thanks!

• Overcrowded Windows XP Folders

  - by BlairHippo

  I know that, technically, an individual Windows XP directory can hold an immense number of files (over 4.29 billion, according to a quick Google search). However, is there a practical ceiling where too many files in one directory starts having an impact on reads to those files? If so, what factors would exacerbate or help the issue? I ask because my employer has several hundred XP machines in the field at client sites, and the performance on some of the older ones is getting "sludgy." The machines download and display client-defined images, and my supervisor and I suspect that our slacktastic approach to cache management could be to blame. (Some of the directories have tens of thousands of images in them.) I'm trying to gather evidence to support or contest the theory before spending time on a coding fix.

• Joining H264 *without* re-encoding

  - by jdmuys

  Hi, I have two halves of a single show in two .MP4 files, encoded in H264. I would like to join them without re-encoding. Is this possible? I managed to create a joined video as a Quicktime file (.mov) using Quicktime Pro, but then Quicktime Pro will not convert it back to .MP4 without re-encoding. This may be because looking inside the .mov file, the two H264 videos are in there still separated as individual "objects". I am also struggling with MPEG StreamClip without reaching a real solution. But I may have missed something. Note that I have the same issue with MPEG2 files. I can export them to a .MPEG container or a .TS file for example, but I don't know how to join them without re-encoding. Any suggestion welcome, preferably using Mac software.

• How to configure/save layout of SQL Server's Log File Viewer?

  - by gernblandston

  When I'm viewing the job history of a particular SQL Agent Job, I typically want to see whether it succeeded, its duration and maybe the duration of the individual steps of the job. When I open the history in the Log File Viewer, I always need to scroll over and shrink the 'Message' column and drag the 'Duration' column over next to the 'Step Name' column. Is there a way to configure the layout of the Log File Viewer (e.g. reposition columns, resize columns) and save it for future sessions? Thanks!

• What's the difference between these Intel things?

  - by Coldblackice

  My head still spins with the various Intel "things" that may (or may not) need installing/configuring/yaddayadda'ing: Intel Rapid Storage Technology (is this driver? a software manager/package?), Intel Chipset (i.e., Intel INF Update Utility, Intel RST OROM, Intel RST driver, Intel Matrix Manager, etc. I think I have a basic understanding that the OROM is the low-level BIOS "driver", which communicates with the higher-level RST driver (in Windows). But what's the Chipset Installation software? What's the INF installation/update software? I'm confused as to what the other pieces are (or why there are so many to begin with). And as for a practical matter -- I'm wanting to upgrade my BIOS with a recent Intel OROM included, and then also update the Intel RST drivers in Windows -- BUT, as for the Windows side of things, I don't know what I should uninstall -- the Intel Chipset installer thing (through official uninstaller), Intel RST Manager, finding the individual Intel devices in Device Manager and right-clicking-uninstall/deleting, etc.

• Password expiration notice for Active Directory

  - by keithosu

  Are there any tools/apps/scripts out there that will do password expiry notification for Windows 2008 Active Directory credentials? This is needed for our web apps that use Active Directory for LDAP authentication. The problem is those apps do not notify you that your password is going to expire when you login. We have many offsite users who do not have machines bound to the AD. So there is no way to let them know to reset their password. I'd like the user to be notified 30,7 and 1 day before it expires. I'd also like our help desk to get an email for the expiring passwords for the week and recently expired passwords. I've looked at oldcmp.exe from link text and that gets me my reports but it does not do the automation that I'm looking for on the individual users.

• TIME column in TOP command for mysql

  - by michael

  When I run top on my database server I get that mysqld has been running for 4:00.51 and it continues to go up. I assume this means that one process with mysql has been running this long from other posts on here. Its not set to cumulative mode as best I can tell as the heading looks like it would change to CTIME if that be the case. What I'm wondering is if this is normal for a site that makes a lot of individual connections using PHP. I shouldn't have any long running processes that would hold on to a mysql connection for this long, only seconds at most. Am I incorrect to assume that this time relates to one connection/process running? I think usually I see it flash up and away on the TOP, not just stay there with this number increasing.

• Building a PC, advice on SSD/Hybrid Hard Drives

  - by Jamie Hartnoll

  I am looking at building a new PC, it's mainly for office (graphics heavy) use and programming. Looking for good performance with opening and closing programs and files as well as a fast boot. I plan to have 3 primary hard drives Windows 7 Programs (photoshop etc) Current Files (There'll also be a large storage capacity back up drive, but this will be the Seagate drive I already have.) So, my question is, looking at standard "old fashioned" hard drives and SSD drives, obviously there's a massive price difference. I have been looking at drives like this: http://www.ebuyer.com/268693-corsair-120gb-force-3-ssd-cssd-f120gb3-bk-cssd-f120gb3-bk and this: http://www.ebuyer.com/321969-momentus-xt-750gb-sata-2-5in-7200rpm-hybrid-8gb-ssd-in-st750lx003 Having no experience of using either I don't know what's the most efficient thing to go for. Clearly the SSD will have better performance, but: If, for example, I had an SSD for Windows (say about 100gB), that would clearly give me the boot speed I want, then I guess my real questions are: If I were to buy one more SSD, would it give the greatest improvement on standard performance if used to store programs, or currently used files? Given that the OS is on an SSD, should I not bother with the 3 drives and instead, partition that Hybrid drive to store programs and currently used files on it? Obviously, option two is cheaper and option one could cause me storage issues, but that's when I can dump files I am not currently using onto another drive. Any, I am open to suggestions... so what do you suggest?!

• Alsa hardware volume with PulseAudio

  - by Jan Hudec

  Before installing pulseaudio, I was able to control volume for the front (meaning on the front panel, the "headphone" jack) and rear (meaning on the back panel, the "line out" jack) separately. When I installed pulseaudio, it became possible to control volume for each playing process separately, but the individual controls for outputs disappeared. While the default device in alsa now routes via pulseaudio, the sysdefault device provides access to the hardware. But kmix does not seem to let me show them now. Is there any way to beat kmix into showing the sysdefault device too? Or something else X-based that would not fight with kmix too much? The system is Debian Jessie (testing) amd64, updated, KDE version 4:4.13.3-1.

• How can I get Skype to not stay minimized in the task bar?

  - by Johannes Rössel

  Since two or three updates Skype insists taking up a taskbar slot for its main window (I set it to use the “Compact View”, but it applies to the default view as well). Since I don't need the main window most of the time since I have individual windows for the contacts I'm writing to this is ? a taskbar button wasted if no other Skype windows are open and ? still in the way when there are other windows open as it's a window I never need but still sometimes mis-click on when the thumbnails show up. Is there a way to send Skype to the Notification area again?

• Passing a file with multiple patterns to grep

  - by Michael Goldshteyn

  Let's say we have two files. match.txt: A file containing patterns to match: fed ghi tsr qpo data.txt: A file containing lines of text: abc fed ghi jkl mno pqr stu vwx zyx wvu tsr qpo Now, I want to issue a grep command that should return the first and third line from data.txt: abc fed ghi jkl zyx wvu tsr qpo ... because each of these two lines match one of the patterns in match.txt. I have tried: grep -F -f match.txt data.txt but that returns no results. grep info: GNU grep 2.6.3 (cygwin) OS info: Windows 2008 R2 Update: It seems, that grep is confused by the space in the search pattern lines, but with the -F flag, it should be treating each line in match.txt as an individual match pattern.

• How important is patch management?

  - by James Hill

  Problem I'm trying to sell the idea of organizational patch/update management and antivirus management to my superiors. Thus far, my proposition has been met with two responses: We haven't had any issues yet (I would add that we know of) We just don't think it's that big of a risk. Question Are there any resources available that can help me sell this idea? I've been told that 55-85% of all security related issues can be resolved by proper anti-virus and patch/update management but the individual that told me couldn't substantiate the claim. Can it be substantiated? Additional Information 1/5 of our computers (the ones on the building) have Windows update turned on by default and anti-virus installed. 4/5 of our computers are outside corporate and the users currently have full control over anti-virus and Windows updates (I know this is an issue, one step at a time).
