• Small, simple LDAP server as an alternative to OpenLDAP

  - by jstarek

  I have taken a look at the installation and configuration instructions for the newer OpenLDAP releases and decided that it's too much work to set up for my small userbase. Basically, I only use LDAP to synchronize user accounts on a small number of machines (ok, this does not really require a directory server) and to give those users access to some web-based tools, avoiding the need to create user accounts in several places. Can you recommend a small, simple LDAP server for use on *nix systems? My only requirements are the ability to serve up PosixAccount and Group objects via LDAP.

• What statistics app should I use for my website?

  - by Camran

  I have my own server (with root access). I need statistics of users who visit my website etc etc... I have looked at an app called Webalyzer... Is this a good choice? I run apache2 on a Ubuntu 9 system... If you know of any good statistics apps for servers please let me know. And a follow-up question: All statistics are saved in log-files right? So how large would these log-files become then? Possibility to split them would be good, dont know if this is possible with Webalyzer though...

• Windows 7 to search a network drive

  - by John

  Is there any way that I can have windows 7 clients be able to go to "start" and type in the name of a file that is located on a network drive? I have read that this is possible through indexing, but to get through the indexing steps I need to make files available offline. This network drive I speak of has about 2tb of files on it. How in the heck can I keep all this straight. I imagine there would be syncing errors everywhere if I were to make all of these files available offline. Not to mention not all files being current due to the large amounts of files. Anyone have suggestions?

• Stream tar.gz file from FTP server

  - by linker

  Here is the situation: I have a tar.gz file on a FTP server which can contain an arbitrary number of files. Now what I'm trying to accomplish is have this file streamed and uploaded to HDFS through a Hadoop job. The fact that it's Hadoop is not important, in the end what I need to do is write some shell script that would take this file form ftp with wget and write the output to a stream. The reason why I really need to use streams is that there will be a large number of these files, and each file will be huge. It's fairly easy to do if I have a gzipped file and I'm doing something like this: wget -O - "ftp://${user}:${pass}@${host}/$file" | zcat But I'm not even sure if this is possible for a tar.gz file, especially since there are mutliple files in the archive. I'm a bit confused on what direction to take for this, any help would be greatly appreciated.

• Running 32 bit SQL Server 2005 on 64 bit Windows Server?

  - by TooFat

  If I have a 32 bit version of SQL Server 2005 running on a 64 bit Windows Server does the max amount of memory avail. the SQL Server process increase from 2gb to 4gb. In reading this blog entry by Mark Russinovich in which he states that "All Microsoft server products and data intensive executables in Windows are marked with the large address space awareness flag" and "Because the address space on 64-bit Windows is much larger than 4GB, something I’ll describe shortly, Windows can give 32-bit processes the maximum 4GB that they can address and use the rest for the operating system’s virtual memory." which leads me to believe that the answer is "yes" but I not totally confident.

• How to block null/blank user-agents in IIS 7.5

  - by Jeremy

  We are going through a large scale DDOS attack, but it isn't the typical bot-net that our Cisco Guard can handle, it is a BitTorrent attack. This is new to me, so I am unsure how to stop it. Here are the stats IIS is processing between 40 and 100 requests per second from BitTorrent clients. We have about 20% of the User Agents, but the other 75% are blank. We want to block the blank user agents at the server level. What is the best approach?

• Best practice for administering a (hadoop) cluster

  - by Alex

  Dear all, I've recently been playing with Hadoop. I have a six node cluster up and running - with HDFS, and having run a number of MapRed jobs. So far, so good. However I'm now looking to do this more systematically and with a larger number of nodes. Our base system is Ubuntu and the current setup has been administered using apt (to install the correct java runtime) and ssh/scp (to propagate out the various conf files). This is clearly not scalable over time. Does anyone have any experience of good systems for administering (possibly slightly heterogenous: different disk sizes, different numbers of cpus on each node) hadoop clusters automagically? I would consider diskless boot - but imagine that with a large cluster, getting the cluster up and running might be bottle-necked on the machine serving the OS. Or some form of distributed debian apt to keep the machines native environment synchronised? And how do people successfully manage the conf files over a number of (potentially heterogenous) machines? Thanks very much in advance, Alex

• Hadoop Rolling Small files

  - by Arenstar

  I am running Hadoop on a project and need a suggestion. Generally by default Hadoop has a "block size" of around 64mb.. There is also a suggestion to not use many/small files.. I am currently having very very very small files being put into HDFS due to the application design of flume.. The problem is, that Hadoop <= 0.20 cannot append to files, whereby i have too many files for my map-reduce to function efficiently.. There must be a correct way to simply roll/merge roughly 100 files into one.. Therefore Hadoop is effectively reading 1 large file instead of 10 Any Suggestions??

• Why does Outlook 2010 give the message "Creating a new item from the selected items could take some time...are you sure you create a new item...?

  - by Matt

  I'm using Outlook 2010 with Exchange 2007. I am moving emails from my Deleted Items folder to a user-created folder. When I move a "low" number of messages, say a few hundred or less, the operation completes successfully. When I move a "large" number of messages (in this example it's over 800) I get the message shown in the screenshot below. If I click Yes, a new email is generated and has links to all the emails I selected in the Attachment field. When I cancel that email, not only have the messages not moved but they appear to be deleted entirely. What does the message mean and why does it get presented? Why does clicking Yes do the behavior I described above?

• Extract photo stills from .vob files

  - by Eric Rath

  My parents had all the family slides scanned by a photo lab. The lab returned the digital photos on two DVDs as movies; there's some stock music over a slideshow with fades between each photo. The discs contain only a handful of files, including some very large VOB files. I'd like to extract these photos and import them into iPhoto. I saw this answer about capturing stills, and that might work if I can figure out the right offset from the beginning and the right capture rate. But this approach seems very error-prone for this purpose. Is there a better way? I wish the individual photo files were stored in a directory on the discs, but they're not there.

• Limiting memory usage and mimimizing swap thrashing on Unix / Linux

  - by camelccc

  I have a few machines that I machine that I use for running large numbers of jobs where I try to limit the number of jobs so as not to exceed the available RAM of the machine. Occasionally I mis-estimate how much memory some of the jobs will take, and the machine starts thrashing the swap file. I resolve this by sending the kill -s STOP to one of the jobs so that it can get swapped out. Does anyone know of a utility that will monitor a server for processes by a specific name, and then pause the one with the smallest memory footprint is the total memory consumption reaches a desired threshold so that the larger ones can run and complete with a minimum of swap file thrashing? Paused processes then need to be resumed once some existing processes have completed.

• Empty AAAA DNS Record with long TTL?

  - by Joel K

  I pay for a DNS service based on queries per second. We are not using IPv6, but a large number of queries (that I pay for) are coming in for AAAA records. I understand that most DNS stacks will now ask for A and AAAAs at the same time, and that I can't change that. What I /would/ like to do is put something in the AAAA records with a long TTL. (decreasing my hit rate) Is there anything I can put? Null? The equivalent IPv4 Address? Any guidance would be appreciated.

• Hard drive placement

  - by zm15

  I'm a video editor working with large HD files. I am building a new computer and need some help. I will be running 2 hard drives. One with the operating system and all the programs. And one with all the project files I will be working from. I am keeping these seperate. I will be purchasing a 10k rpm hard drive. So i will have a 10k rpm drive, and a 7200rpm drive. Should I put the OS on the faster drive, or put my working files on the faster drive?

• copying corrupted images from a dvd.

  - by Pennf0lio

  Hi, Are there software you know that can copy images from a DVD? now the problem is there images in the DVD that are corrupt that I won't force to copy, If the software can recover the file and copy it that would be cool, If it cannot then skip the file. The dvd is kinda large and I don't want to sit and wait there. I want the DVD do the decision, If it can recover then recover if it cannot, then skip. And do you know other solution copying corrupt files? thanks!

  - by Matthewhall58

  I have a windows server and a centos linux server. I want the nightly backup file (targz) that copies to the windows machine to use a different nic so that the main nic is not burdenend with moving the large file. Each server has 2 Nics in it. the network is 10.173.10.0 mask 255.255.255.192 Centos Linux Box: Eth0 is configured with 10.173.10.80 mask 255.255.255.192 gw 10.173.10.65 Eth 1 is configured with 10.173.10.71 mask 255.255.255.192 gw 10.173.10.65 Windows Box Eth 0 is 10.173.10.72 mask 255.255.255.192 gw 10.173.10.65 Eth 1 is 10.173.10.70 mask 255.255.255.192 gw 10.173.10.65 I can ping each machine from each machine. On the linux machine I use the command route add -host 10.173.10.70 dev eth1 but then when i ping 10.173.10.70 it is unreachable..... WHY?

• What is your approach to draw a representation of your network ?

  - by Kartoch

  Hello, I'm looking to the community to see how people are drawing their networks, i.e. using symbols to represent complex topology. You can have hardware approach, where every hardware unit are represented. You can also have "entity" approach, where each "service" is shown. Both are interesting but it is difficult to have both on the same schema (but this is needed, especially using virtualization environment). Furthermore, it is difficult to have complex informations on such representation. For instance security parameters (encrypted link, need for authentication) or specific details (protocol type, ports, encapsulation). So my question is: where your are drawing a representation of your network, what is your approach ? Are you using methodology and/or specific softwares ? What is your recommendations for information to put (or not) ? How to deal with the complexity when the network becomes large and/or you want to put a lot of information on it ? Examples and links to good references will be appreciated.

• Why does yum index get corrupted?

  - by TomOnTime

  Occasionally yum's cache gets corrupted and we see errors like this: error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery error: cannot open Packages index using db3 - (-30974) error: cannot open Packages database in /var/lib/rpm The workaround is rm -f /var/lib/rpm/__db* and then the next "yum" command regenerates the data. My question is: what is likely to be causing this? Is there some common task that ignores locks or has other problem that causes this? We have hundreds of CentOS machines and there is no pattern to which see this problem. It could be a "one in a million" issue, which at large scale is seen often. NOTE: I realize this is a very "open ended" question, but if an answer finds the cause, I will go back and turn the question into something more canonical that directly relates to the specific issue.

• InnoDb Overhead?

  - by Rimary

  I just converted several large tables from MyISAM to InnoDB. When I view the tables in phpMyAdmin, they are showing a significant amount of overhead (One table has 6.8GB). Optimizing the tables (which isn't a supported command on InnoDB) has no affect like it does on MyISAM. Is this a result of InnoDB having the ever growing data file that never returns space even after deletes? If that's the case, I've never seen overhead like this before from other InnoDB tables. Is there a way to clean this up? Edit: Here are the things I've tried (with no success): Optimize Table Reorder table by primary key Defragment table

• What is OpenSVC?

  - by sh-beta

  OpenSVC was just ported to the FreeBSD platform. The little blurb in that announcement intrigued me so I went to the OpenSVC website and found this: OpenSVC is a 'service' manager, as in clustered service manager, designed for real-world heterogeneous datacenters and large-scale operations orchestrator (disaster recovery, for example). Services are collections of resources (virtual machine, ip, disk groups, filesystems, file synchronizations, and application launchers). Services can be started, stopped and queried for status, providing a consistent command set for wildly different service integration types. Service configurations, status and logs are pushed to a central database coupled to a web front-end (collector). Services can be administered using the stand-alone GPLv2 software stack deployed on the nodes (nodeware), or through the web-front end. Plus some UML-type graphics. Which is all neat, but I still don't understand: what does it do? Am I just being dense? What's the use case for this system?

• Linux freezes every few seconds

  - by Zeppomedio

  We're having an issue where one our Linux boxes (Ubuntu 10.04 LTS, running on EC2 with a quadruple-large size, 68GB of RAM and 8 virtual cores with 3.25GHz each) freezes up every few seconds. Typing in an ssh session will freeze, and running strace on one of the Postgresql processes that's running usually shows: 02:37:41.567990 semop(7831581, {{3, -1, 0}}, 1 for a few seconds before it proceeds (it always gets stuck at that semop). OProfile shows that most of the time is spent in the kernel (60%) versus 37% in Postgresql. The result of these halts (which began suddenly a day ago) is that load on the box has gone from 0.7 to 10+, and causes our entire stack to slow done. Any ideas on how to track down what's going on? iostat doesn't show the disks being particularly slow or overloaded, and top shows user cpu % spike from 8% to about 40% whenever these back-ups happen.

• Can the JVM(Oracle) run into an OutOfMemory error if the heap size is below the max?

  - by user439407

  I am running a Tomcat site(with an NGinx front end) that seems to be randomly running out of memory even though the max heap size is pretty large. My question is is it possible for the JVM to get an OutOfMemory error even if the heap size is significantly less than -Xmx? For instance, here is a snapshot I took just 15 seconds before an OutOfMemory error: Tue Dec 18 23:13:28 JST 2012 Free memory: 162.31 MB Total memory: 727.75 MB Max memory: 3808.00 MB I guess theoretically it's possible that my code generated 3 gigs worth of objects in 15 seconds, but I highly doubt it. It seems like the JVM was unable to grow the heap even though it theoretically had room....Is it possible that other processes started using memory to the point that the JVM could not grow? I am running 64-bit Oracle Hotspot on a 64 bit vm running CentOS 5 with 6 gigs of ram.

• Excel 2010 -Excel cannot complete this task with available resources

  - by Jestep

  Getting this error when trying to sort a document (Excel cannot complete this task with available resources). Document isn't particularly large, about 4,000 lines. Can't seem to figure out why this would start on this. I can sort this same file fine on everything back to Excel 2000 on older crappy computers. Computer is running Win 7 x64, 16 Gb RAM, and another 16 Gb of virtual. There's no possible way that all of the memory is actually getting exhausted when I can perform this on an older XP machine with 512 Mb of RAM, unless 2010's memory usage is inconceivably poorly designed. I found a few posts on forums stating that there might be a security update related bug. Any suggestions would be appreciated.

• SSL on Apache seems to significantly affect WebDAV performace

  - by takesides

  I'm using Apache 2.2 running on Windows Server 2008 R2 as a WebDAV server for clients to upload large media files (roughly 100-2000MB). I am finding that when I have SSL enabled (openSSL 0.9.8o) and use HTTPS for the uploads the throughput is around 13Mbps but when I disable it and just use HTTP I get around 80Mbps. I can't understand why this is happening as my understanding was that the heavy SSL work was done at the beginning of the connection. Does anyone have any idea why the performance is so drastically affected by enabling SSL? Cheers.

• Move /var directories to to /mnt on an EC2 instance

  - by Geoff Lanotte

  I am trying to work on a standard configuration for a set of EC2 instances running ubuntu 12.04. These servers are going to be primarily web servers for a Ruby on Rails application. When you configure a new large instance, you are given a primary of 8GB and then ephemeral storage of 400 GB that is mounted to /mnt. It seems logical to me to move some directories that have a potential for growth off to the /mnt directory, I was specifically thinking of /var/www and /var/log. My question is two-fold: Is this a good idea or are there pitfalls that I cannot see? If this is a good idea, how should I go about configuring this. I do have the ability to configure new instances and down our old instances. My concern is over long term, doing this in such a way that it prevents downtime. I am a developer with some experience in devops, but mounting drives is something I have not faced before, so explicit directions would be greatly appreciated.
