  • Heartbeat won't start up from a cold boot when a failed node is present

    - by Matthew
    I currently have two ubuntu servers running Heartbeat and DRBD. Let's say one node is down... The servers are directory connected with a 1000Mbps cross over cable on eth1 and have access to a IP camera LAN on eth0 The node that is still functioning won't start up heartbeat and provide access to the drbd resource. I have to manually restart heartbeat by "sudo service heartbeat restart" to get everything up and running. How can I get it to start fine from a cold start? Here is the my ha.cf and some material from the syslog... If I'm missing any information that might be of some help. http://pastebin.com/rGvzVSUq <--- Syslog http://pastebin.com/VqpaPSb5 <--- ha.cf

  • Intraforest user account merge with Active Directory

    - by Neobyte
    I have a scenario where there is a root domain (RD) and two child domains (CD1 and CD2). Users have accounts on both CD1 and CD2, with identical samAccountNames, names etc, and various applications either use the CD1 or CD2 account for authentication to resources. I need to collapse CD2 into CD1, so I want to merge the accounts together. However ADMT does not allow me this option (merge options are greyed out), I think because it does not support intraforest merge of accounts (although it does not explicitly state this anywhere in the documentation). My question is - what is the easiest way for me to merge these accounts? Ultimately all I really need (I think) is for the SID of CD2\user1 to be added to the SIDHistory of CD1\user1 - is there a tool that supports this? Computer accounts and profiles are not a concern for this scenario. Group migration is unlikely to be an issue either - CD2\user1 is usually granted resource access through membership of a group on CD1.

  • Patch msp into msi package

    - by Kvad
    The latest update of Windows Live Messenger is an msp added to the package. I want to patch a msp into an msi. Reference download http://wl.dlservice.microsoft.com/download/8/3/D/83D75746-DF04-45E9-8374-BD31B9419128/en/wlsetup-all.exe I extract all msi and msps from this. (To get the msp and msi's I did the following Use resource hacker to open up wlsetup-all.exe In the left hand tree browse to PACKAGE Right click PACKAGE, save PACKAGE resources Save to a new temp folder Eg. D:\temp\package.rc This will output a whole lot of .bin files These are just cab files so we need to do a mass rename “ren *.bin *.cab” Once done select all cab files and extract to a new sub folder \extracted In \extracted you will see all the msi, msp and 7z files you need) I try to apply the msp directly with no result msiexec /p messenger.msp /a messenger.msi I also try doing a admin install with nothing being extracted.

  • Installing Domain Controller on Hyper-V Host

    - by MichaelGG
    Given a resource limited setup consisting of 2 host machines (HyperV-01 and HyperV-02), is it OK to put the domain controllers in parent partition, instead of their own VM? The main reason is that if the DCs go into a child partition, starting from cold on both machines could lead to a bit of an issue, as there'd be no DCs around until well after both parents have booted. I'm guessing this might cause undesirable effects. Am I correct to be worried about joining the host systems to a domain that's only on VMs? The biggest drawback I've heard so far is that if AD gets heavily used, its resources could cut into HyperV's. I'm not concerned about that for this deployment. Any other suggestions? (Besides finding a 3rd machine and running AD on it.)

    - by Mit Naik
    Just found userfull information on Internet and thought it would help all of users. This list of startup applications is a really handy resource for cleaning up msconfig entries that have overtaken old computers. It catalogs tons of different startup programs, what they do, and which ones you should delete, leave running, or decide based on the program's usefulness. It even has a nice search box so you can search through the tens of thousands of entries. Hit the link below to check it out, and if your relatives' computer is especially broken, be sure to check out our guide to fixing your relatives' terrible computer. http://www.sysinfo.org/startuplist.php Please update the list here if you got any other tools or sites which can be help full to others

  • decrypting AES files in an apache module?

    - by Tom H
    I have a client with a security policy compliance requirement to encrypt certain files on disk. The obvious way to do this is with Device-mapper and an AES crypto module However the current system is setup to generate individual files that are encrypted. What are my options for decrypting files on-the-fly in apache? I see that mod_ssl and mod_session_crypto do encryption/decryption or something similar but not exactly what I am after. I could imagine that a PerlSetOutputFilter would work with a suitable Perl script configured, and I also see mod_ext_filter so I could just fork a unix command and decrypt the file, but they both feel like a hack. I am kind of surprised that there is no mod_crypto available...or am I missing something obvious here? Presumably resource-wise the perl filter is the way to go?

  • setting nproc in /etc/security/limit.conf prevents ssh login

    - by omry
    I am trying to use /etc/security/limit.conf on Linux (Debian) to limit the number of processes per user. for starters, I tried to limit my own user processes by adding this to /etc/security/limit.conf: omry hard nproc 100 this locked my user out of ssh. I could open new processes (verified with su omry), but could not log into ssh with that user : sshd reported this in it's log: fatal: setreuid 1000: Resource temporarily unavailable also, I am certain my user is not running anything near 100 processes (actually 6). what can be the reason for this?

  • java: can't use constructors in abstract class

    - by ufk
    Hi. I created the following abstract class for job scheduler in red5: package com.demogames.jobs; import com.demogames.demofacebook.MysqlDb; import org.red5.server.api.IClient; import org.red5.server.api.IConnection; import org.red5.server.api.IScope; import org.red5.server.api.scheduling.IScheduledJob; import org.red5.server.api.so.ISharedObject; import org.apache.log4j.Logger; import org.red5.server.api.Red5; /** * * @author ufk */ abstract public class DemoJob implements IScheduledJob { protected IConnection conn; protected IClient client; protected ISharedObject so; protected IScope scope; protected MysqlDb mysqldb; protected static org.apache.log4j.Logger log = Logger .getLogger(DemoJob.class); protected DemoJob (ISharedObject so, MysqlDb mysqldb){ this.conn=Red5.getConnectionLocal(); this.client = conn.getClient(); this.so=so; this.mysqldb=mysqldb; this.scope=conn.getScope(); } protected DemoJob(ISharedObject so) { this.conn=Red5.getConnectionLocal(); this.client=this.conn.getClient(); this.so=so; this.scope=conn.getScope(); } protected DemoJob() { this.conn=Red5.getConnectionLocal(); this.client=this.conn.getClient(); this.scope=conn.getScope(); } } Then i created a simple class that extends the previous one: public class StartChallengeJob extends DemoJob { public void execute(ISchedulingService service) { log.error("test"); } } The problem is that my main application can only see the constructor without any parameters. with means i can do new StartChallengeJob() why doesn't the main application sees all the constructors ? thanks!

  • How to check the backtrace of a "USER process" in the Linux Kernel Crash Dump

    - by Biswajit
    I was trying to debug a USER Process in Linux Crash Dump. The normal steps to go to the crash dump are: Go to the path where the dump is located. Use the command crash kernel_link dump.201104181135. Where kernel_link is a soft link I have created for vmlinux image. Now you will be in the CRASH prompt. If you run the command foreach <PID Of the process> bt Eg: crash> **foreach 6920 bt** **PID: 6920 TASK: ffff88013caaa800 CPU: 1 COMMAND: **"**climmon**"**** #0 [ffff88012d2cd9c8] **schedule** at ffffffff8130b76a #1 [ffff88012d2cdab0] **schedule_timeout** at ffffffff8130bbe7 #2 [ffff88012d2cdb50] **schedule_timeout_uninterruptible** at ffffffff8130bc2a #3 [ffff88012d2cdb60] **__alloc_pages_nodemask** at ffffffff810b9e45 #4 [ffff88012d2cdc60] **alloc_pages_curren**t at ffffffff810e1c8c #5 [ffff88012d2cdc90] **__page_cache_alloc** at ffffffff810b395a #6 [ffff88012d2cdcb0] **__do_page_cache_readahead** at ffffffff810bb592 #7 [ffff88012d2cdd30] **ra_submit** at ffffffff810bb6ba #8 [ffff88012d2cdd40] **filemap_fault** at ffffffff810b3e4e #9 [ffff88012d2cdda0] **__do_fault** at ffffffff810caa5f #10 [ffff88012d2cde50] **handle_mm_fault** at ffffffff810cce69 #11 [ffff88012d2cdf00] **do_page_fault** at ffffffff8130f560 #12 [ffff88012d2cdf50] **page_fault** at ffffffff8130d3f5 RIP: 00007fd02b7e9071 RSP: 0000000040e86ea0 RFLAGS: 00010202 RAX: 0000000000000000 RBX: 0000000000000000 RCX: 00007fd02b7e9071 RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000040e86ec0 RBP: 0000000040e87140 R8: 0000000000000800 R9: 0000000000000000 R10: 0000000000000000 R11: 0000000000000202 R12: 00007fff16ec43d0 R13: 00007fd02bcadf00 R14: 0000000040e87950 R15: 0000000000001000 ORIG_RAX: ffffffffffffffff CS: 0033 SS: 002b If you check the above backtrace it shows the kernel functions used for scheduling/handling page fault but not the functions that were executed in the USER process (here eg. climmon).

  • Redirect some URL requests to CloudFront and the rest direct to the normal server?

    - by indiehacker
    Say I have two types of URL requests that must be handled by my REST API: http://query.restapi.com/image.png?apikey=abc123 http://query.restapi.com/2.0/<apiKey>/resource.json?from=umi.us_census00.state_geometry Is it possible to redirect only some URL requests for static images (ie., regex: *.png?.*) to take advantage of CloudFront's caching and have the rest of the requests go directly to the normal EC2 server (or at least take a speedier indirect route to the normal EC2 server?). Perhaps the added request time for the misses to CloudFront is irrelevant to worry about? Or perhaps my situation is not best to use for CloudFront? I understand I will need to make DNS change where the current URL requests having http://query.restapi.com/some.png?apikey=0123 get redirected to http://d1234.cloudfront.net/some.png, but I am hoping there is some way for just redirecting static .png requests to take advantage of CloudFront?

  • Logging another person off in Windows 7 using Task Manager

    - by BBlake
    Under WinXP, I could use Task Manager's Users tab to log off my wife's account which she always leaves logged in so I don't have to log in to her account and log it out. It's an older machine so I used that trick to free up every resource I could which might potentially slow down the game I'm playing at the time. I recently upgraded the machine to Win7 and when I try the same trick, I get an access denied popup. My logged in account does have Admin rights, so is it as simple as runing Task Manager "as an Administrator" in order to allow this? If so, how can I pull up Task Manager (other than the standard CTRL-ALT-DELETE) to have it pop up with Admin rights in order to log her account off in this manner?

  • Windows 7 stopped connecting to samba share

    - by Jan
    I have a problem with Windows 7 Home connecting to samba on linux server. It's worked fine for a year and without any changes in configuration or updates it suddenly stopped working. The strangest thing for me is that it stopped working for no reason that I could think of. After a few minutes after trying to connect I get: \\ip is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Other computers in that network (XP machines) connect to samba without any problem. I've tried adding LmCompatibilityLevel as described here: http://www.tomshardware.com/forum/75-63-windows-samba-issue , but it didn't help.

  • How does the data storage work? [closed]

    - by Andres Adhi
    I am really new to the whole concept of Data storage, Domain, Server and everything else related to this. Can someone pleases explain what a Domain is? How are server part of the Domain and How are Database stored in the Server or Domain? How does a new server be able to connect to existing database server to get all the data needed. I tried to find this information in the web but I am not really finding a good resource. It may be because these is really basic information. I will really appreciate if someone can explain these concept in plain terms. Thanks in advance.

  • First time setting up a MySQL database.

    - by Wilduck
    In trying to learn how to work with the LAMP stack, I've hit a wall with MySQL. I can't seem to find a good reference for the first time setup of MySQL to be used with Apache and python. So, my question is four-fold: 1) Under what circumstances should I create my first database. That is, what user do I use (Apache's http user? root?) 2)How do permissions work? 3) Do I have to do anything on the MySQL side to make MySQL talk to Apache, or MySQL to talk to Python/Django? 4) Is there a good resource online that describes setting all of this up? I've found a bunch for using a database once it's in place, but none for the initial setup? Notes: I'm trying to run my LAMP stack on a dedicated little box for testing/learning purposes only, so I don't have access to any DBA that could help me, as much as I'd like one.

  • Microsoft Cluster or Oracle Fail Safe error

    - by osdm
    Trying to get Oracle Database 10g to work on Microsoft cluster (using Oracle Fail Safe, not RAC). Everything installed, but when trying to verify group or add database to group I get following error: FS-10220: Network name MSK00-NST01-1 maps to IP address 10.1.11.74 in the cluster resource but maps to IP address 10.1.1.74 on the system MSK00-NST01-1 is cluster name, 10.1.11.74 is first node IP, 10.1.1.74 is second node IP. Oracle documentation says "The cluster and the system must have the same IP address mapping for a network name. Check that either the network name server or the local host file has the same IP address mapping as the cluster." Where is the error - in Oracle configuration or in cluster configuration? What are possible ways to correct it? Thanks a lot for any ideas.

  • Virtual Machine files on ramdisk doesn't run faster than on physical disk

    - by Landy
    I installed total 36G memory (4x8G + 2x2G) in the host (Windows 7) and I used ImDisk to create a 32G ramdisk and format it to NTFS file system. Then I copied the virtual machine (in VMware Workstation format) folder, including vmx, vmdk, etc... to the new created ram disk. Then I tried to power on it in VMware Workstation. What made me surprised is that the performance is not better than before. It cost almost the same time to power on the Windows 7 VM. I check the Resource Monitor in the Windows 7 host, and the statistics of CPU, disk, network are rather normal. The memory has reported 3000+ hard fault/sec when guest OS boot then drop to 0 after the guest powered on. Any idea about this issue? I had thought the performance of ramdisk will be better than physical disk in this case. Am I wrong? Thanks.

  • Chrome drag and drop download links

    - by Brad
    In Chrome, I used to be able to take a link to a file and just drag to a folder on my system. Chrome would then download whatever resource was at the URL for the link and put it into the folder dropped into. This was particularly handy when using Gmail. If there was an attachment, I could just click and drag it into a folder, and Chrome would download it for me to the correct place. Now I have to hit download, and then drag from the download bar when it is finished. Has this feature been removed? Is there any way to bring it back?

  • Is it illegal to download (from torrents) software that you have already legally bought?

    - by joshhunt
    With Snow Leopard now out, I decided to order myself a copy. But as I bought it online, it takes six to eight weeks three to five days for to to arrive via snail mail, but I want it now. Seeing that I have already legally bought a license for Snow Leopard, can I download a retail version of Snow Leopard from a torrent, without breaking the law? I understand that the law varies from country to country, so I acknowledge that this may be a tough question to answer sufficiently. I am in Australia, so I suppose I am mostly interested in answeres regarding Australian law, but other counties (or a general response) are also fine NOTE: SuperUser is NOT a legal resource and any advice/answers here should NOT be used as legal advice in any way.

  • Slow LAN transfer from 3rd party computer

    - by Chris
    Hi Everyone, I've got an odd problem that I'm not really sure where to start the troubleshooting process. I have a 'server' with Windows Server 2008R2 (64-bit) installed and it has a couple of hard drives. If I Remote Desktop into the server and transfer files from one HD to the other, all it fine. If however, I use my workstation (Windows 7 64bit) and open up a shared resource on the server and transfer a file from one hard drive on the server to another HD on the server (not using Remote Desktop, just Windows explorer/Network places), the transfer crawls... It takes about 5mins to discover files/calculate the transfer and then starts transferring at speeds like 56KB/s - 200KB/s. Both machines have Marvel GigE network ports with a TrendNet 8-port green GigE switch. I've set Jumbo packets to 9K on both machines...

  • Can I use a Google Appliance/Mini to crawl and index sites I don't own?

    - by SkippyFire
    Maybe this is a stupid question, but... I am working with this company and they said they needed to get "permission" to crawl other people's sites. They have a Google Search Appliance And some Google Minis and want to point them at other sites to aggregate content. The end result will be something like a targeted search engine. (All the indexed sites relate to a specific topic) The only thing they will be doing is: Indexing Content from the other sites/domains Providing search functionality on their own site that searches the indexed content (like Google, displaying summaries and not the full content) The search results will provide links back to the original content Their intent is not malicious in nature, and is to provide a single site/resource for people to reference on their given topic. Is there anything illegal or fishy about this process?

Tanenbaum and I wonder if anyone else has any experience with that title. It’s expensive but I could probably loan a copy for £3 from the library or so.
