  • McAfee ePolicy-Orchestrator (ePO) - policy ownership by groups?

    - by bkr
    Is there a way to grant ownership of an ePO policy to a group? Alternatively, is there a permission that can be set that would allow owners of an ePO policy to add other owners to that policy without making them ePO admin? In the case I'm looking at, ePO is deployed within a large heterogeneous organization with a large amount of delegation in the form of create/modify policy rights to allow multiple IT departments to customize to their needs for their sections of the system tree. The problem is that the policies are owned by the creator of the policy. This causes problems when they leave (staff turnover) or when other people on their teams need the ability to modify the existing policy. Unfortunately, as far as I can see, only someone who is an ePO admin can change the owners. Even the owner of the policy cannot add other owners (unless they are also an ePO admin). Ideally, I should be able to assign ownership of a policy to a group - since that would be easier to manage than me or another admin having to continually fix policy ownership or remove orphaned polices. Even just allowing the owners of the polices to add other owners would be sufficient. How are other people handling policy ownership when dealing with a large amount of delegated control of polices? Is there a way to delegate this out without making users full ePO admins?

  • Connecting a Wifi router to receivers with a cable instead of antenna?

    - by 31eee384
    This is a very strange question--I'd go so far as to say it's a stupid question. I'm being told that it is possible to, to describe it briefly, use a cable to connect an access point and a receiver directly to one another. This means that I would unscrew the access point's antenna, and attach one end of a cable to the port. Then, on the wireless receiver, I would also unscrew the antenna and plug in the other side of the cable. I'm being told the connection would work after this, just as a normal Wifi connection would. Bonus mini-question: if this works, would it still work if a splitter were attached to the access point and multiple receivers plugged in to the network? What would happen if I do this? Based on my surprisingly deficient knowledge of radio transmission, I don't think it would work. I would like some help knowing why it won't (or will) though, if possible. This is a somewhat hypothetical question--I realize that Ethernet does this exact job very handily, and I could just throw in a switch instead of the splitter. I simply feel that I should understand this scenario. Thanks for any help you can offer.

  • Recover badly recorded DVDs

    - by CesarGon
    A few years ago (2003-2005) I bought a Sony USB external DVD recorder for my Dell laptop and I used it to burn a lot of discs. Much later, when I tried to use one of these discs, I realised that I could not read it. The disc behaved as if it was scratched or dirty. I tried on a couple of different DVD drives but got the same effect. Sadly, all the discs that I burnt with that recorder suffer from the same problem. Edit. When I read one of these discs with ImgBurn, I get lots of unrecovered read errors in multiple sectors, even at 1x speed. The sectors that cause read errors seem to be quite random; it's not always the same one. I have no idea what could be wrong with the discs. I doubt that they are scratched or dirty; it would be too much of a coincidence that all the discs that I burnt with that recorder got damaged at the same time. Also, they don't show any physical defects. Is there any way to diagnose what the problem is and, hopefully, recover the contents of the discs? Many thanks.

  • Outdoor WiFi Mesh Topology vs. Repeaters

    - by IronJaxor
    Here's the current configuration in our organization (which I believe is incorrect): We have a number of Cisco 1500 series AP's (22 in total), that are mounted outdoors to provide seamless WiFi coverage over a large area. Each AP however has its own physical ethernet connection back to the WLC (All the AP's are marked as Root AP's). They are all broadcasting the same SSID. We have tried to stagger the channel selection but because there are only three non-overlapping channels to choose from, and in some areas the density of AP's is quite high, there is multiple places of channel interference. With this configuration we experience 100-150 disconnects from clients every day. (Our clients are mobile so they move throughout the coverage area constantly). My idea is to switch the AP's to the same channel thereby forming a wireless mesh, use the built in functionality of the 1500 series to use 802.11a as the backhaul, designate one or two AP's as root AP's and wire them back to the WLC. Thereby forming a WiFi mesh, which if I'm not mistaken is the point of the 1500 series in the first place! I am however completely new at WiFi networks and wondering if I am simply mistaken in what I believe my proposed changes will enable, or if there is a better way to tackle the WiFi topology.

  • Computer randomly shuts itself off

    - by Decency
    I have not been able to determine a pattern for why this happens, despite my best efforts. I've attempted to run it on full power with Prime95 and this doesn't trigger a restart. Generally the restarts occur while I'm playing games, watching videos, or even just having multiple tabs open in a browser. However, I often play processor intense games for hours without any restarts occurring, and sometimes they'll happen 3-4 times in an hour during less intense activity, so I don't think that is the problem. I imagine it has something to do with overheating or power consumption so I've been monitoring CPU temperature and cleaning with compressed air, but the problem keeps happening. I don't know how to track power consumption, and assume that this is the problem. Whenever this occurs, the sound gets stuck in a short loop of whatever was playing at the time, though restarts also occur when nothing is playing. Here is a screenshot of temperatures: and under load: Here's the parts list: http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=10546754 As shown in the list, the case includes a 585W Power Supply, which I've been told should be plenty. I built the computer myself with a friend's guidance but it's very possible I did something wrong. Right now I'm looking into ensuring that I have the latest drivers for all components. Any help would be appreciated- thanks.

  • Windows Server 2008 IIS Random disconnect

    - by d123
    I am having a bit of a quirk with my IIS server. I'm running my IIS with 2 sets of IPs configured, one in the 192 range and the other in 172 range. I then have multiple apps which will talk to this server for information. Server has no AV or firewalls configured. I noticed that my apps when talking to the server on the 172 range, at random intervals, the server would just not respond. My apps would then disconnect and just try again, and every thing would be fine. This doesn't happen on the 192 range. So what I did is on a Linux box I did a watch command and to wget a file every half second on the 172 and 192 IPs. I noticed the same issue, every once in awhile wget on the 172 range would not get through, but there is no issues at all on 192. Thus I went around to Wireshark and did a dump. This is the last 3 packets, no other packets were received. 7010 100.871877 200.100.30.7 172.0.0.1 TCP 59619 http [ACK] Seq=140 Ack=85242 Win=64128 Len=0 TSV=1072818795 TSER=1660246133 7011 100.872238 200.100.30.7 172.0.0.1 TCP 59619 http [FIN, ACK] Seq=140 Ack=85242 Win=64128 Len=0 TSV=1072818796 TSER=1660246133 7013 100.873081 200.100.30.7 172.0.0.1 TCP 59619 http [ACK] Seq=141 Ack=85243 Win=64128 Len=0 TSV=1072818796 TSER=1660246133 So this is my issue, there is a random disconnect every once in awhile. The server doesn't receive the next SYN packet. HELP?

  • Blocking of certain file downloads

    - by Philip Fourie
    I have a problem where I cannot completely download a certain file from a server. The file is 1.9MB in size but only 68% is downloaded and then it hangs. I tried and these cases, which failed: Downloaded the file with HTTP Downloaded the file with FTP Moved the file to different FTP and web servers behind the ISA firewall Tried with IIS 6.0 & IIS 7.0 Multiple download clients. Which included FireFox, FileZilla (on Windows) and wget (on Linux) This worked: Downloading other files from the same location on the server. Both bigger and smaller and in size than the original. FTP and HTTP worked. Earlier version of this file (.DLL) works. It is as if the content of this file has an influence on this file being served. Network architecture: Client Machine - Internet (ISP) - ISA Server - IIS 7.0 The only constants are the ISP, Cisco router and the ISA server. Is it possible that something is rejecting the download because of the contents of the file? I am hoping ISA is the culprit... I am not a ISA expert is there somewhere I can look to establish if it is indeed ISA causing this? Update: Splitting the file into two parts with a hex editor results in one half of the file being served correctly and the other part not. Zipping the file results in the file being downloaded successfully. However this is not an option for this particular scenario. Renaming the file and its extension also doesn't work. Update 2009/10/22: It does NOT seems to be ISA that is causing this problem. We connected a laptop (running IIS) on an available public IP and still the file download to 68% before it hanged. The two remaining components are the ISP and the Cisco 800 series router. Anyone knows about an issue on the router perhaps?

  • Setup ejabberd with SQL Server 2008

    - by wonster
    Here's what I have got so far. Windows 2008 Server 64 bit. Installed the latest version of ejabberd, ejabberd-2.1.8-windows-installer.exe. The windows service starts up fine but seems ineffective. However, using the start & stop scripts work. I am able to login to the admin page which so far doesn't seem that versatile. Opened up ports 5222, 5226 and 5280 for my workstation to talk to the server. I've got Spark and Jabbear Windows clients to register, login and instant message with multiple accounts using the server. After confirming that I've got the very basics working, I've decided to make use of SQL Server 2008 as the database. Reason? Mainly, I am very comfortable with SQL Server. I can deal with redundancy, failover, data analysis easily. Not sure if ejabberd's built in DB provides all that. Following the instructions from ejabberd's documentation, I setup a system DSN that points to another physical database. The DSN checks out fine. (Tried both Named Pipes and TCP/IP) Modified ejabberd.cfg. Commented line %%{auth_method, internal} and uncommented line {auth_method, odbc} Uncommented and modified {odbc_server, "DSN=ejabberd;UID=somelogin;PWD=somepassword"}. After making these changes, I restarted. No errors are found in the log files. The jabber clients are no longer able to register new accounts. I'm not sure where to look for errors besides the /logs/ folder as I'm new to all this. I am basically stuck here on step 5. Has anyone got this setup to work recently? Some of the posts I've found around are years old and of no help. I can't be the only one setting up ejabberd with MS SQL. Any help would be appreciated!

  • Interaction between two Clouds

    - by Snehal Masne
    I have setup the Cloud-A with 1 - [CLC+CC] and 2 - [NC] computers. I have another Cloud-B with same configuration. [using the Ubuntu Enterprise Cloud] Both of them working fine individually, in the same LAN. Now if I want to add the NC of Cloud-A to CC of Cloud-B, [in case the resources of Cloud-B are exhausted] how can I make it possible ? I guess this calls for the interoperability stuff... Could you please explain what happens exactly when we ask for instance, the direct interaction happens between the client and NC or it goes through the CLC and CC ? What I want to say is, say there are multiple cloud providers. A user is subscribed to any one of them, say Cloud-A for IaaS. As the requirements are dynamic, all the resources of Cloud-A may get exhausted. There may be another Cloud-B which can provide the services but that Cloud-A can't ask the client to go for Cloud-B. So if it is possible to have some co-ordination between this two providers to share resources mutually, making client fully unaware of whats going on in the background....? Please reply.. I am sorry if I'm doing mistake anywhere... Thanks in advance :) Regards, www.TechProceed.com

  • How to deal with ssh's "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!"?

    - by Vi.
    I often need to login to multiple remote stations that are just placed to the same static IPs for me. SSH complains about changed keys in this case: $ ssh [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ ... Offending RSA key in /home/vi/.ssh/known_hosts:70 ... I usually just run vim /home/vi/.ssh/known_hosts +70, dd wq and re-run the SSH command. How to do it simpler? Requirements: The warning should be displayed, and not like this: The authenticity of host '172.1.2.3 (172.1.2.3)' can't be established. It is easy to accept the key change. I expect something like this: $ ssh [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ ... The fingerprint for the RSA key sent by the remote host is 82:cd:be:7a:ae:1b:91:2c:23:c1:74:4d:8a:38:10:32. Change the host key in /home/vi/.ssh/known_hosts (yes/no)? yes Warning: Changed host key for '172.1.2.3' (RSA) in the list of known hosts. [email protected]'s password: Simple and differs from usual "The authenticity of host can't be established." message.

  • Apache Named Virtual Hosts and HTTPS

    - by Freddie Witherden
    I have an SSL certificate which is valid for multiple (sub-) domains. In Apache I have configured this as follows: In /etc/apache2/apache2.conf NameVirtualHost <my ip>:443 Then for one named virtual host I have <VirtualHost <my ip>:443> ServerName ... SSLEngine on SSLCertificateFile ... SSLCertificateKeyFile ... SSLCertificateChainFile ... SSLCACertificateFile ... </VirtualHost> Finally, for every other site I want to be accessible over HTTPS I just have a <VirtualHost <my ip>:443> ServerName ... </VirtualHost> The good news is that it works. However, when I start Apache I get warning messages [warn] Init: SSL server IP/port conflict: Domain A:443 (...) vs. Domain B:443 (...) [warn] Init: SSL server IP/port conflict: Domain C:443 (...) vs. Domain B:443 (...) [warn] Init: You should not use name-based virtual hosts in conjunction with SSL!! So, my question is: how should I be configuring this? Clearly from the warning messages I am doing something wrong (although it does work!), however, the above configuration was the only one I could get to work. It is somewhat annoying as the configuration files have an explicit dependence on my IP address.

  • Remote Desktop Services Licensing - Does server have to have a RDS role?

    - by transistor1
    I recently set up a "micro" size Windows 2008 Datacenter server on Amazon AWS. My small group needs several concurrent RDS users to be able to access the machine. Without installing the "Remote Desktop Server" role, it allows 2 concurrent connections. I read on MS' website that in order to set up multiple users, we needed to install the RDS role. I did so, but now the application we are trying to share is running much slower than it was before. Prior to the role installation, it was taking about 5 seconds to open; now it is taking a few minutes to open -- without any other users logged on except me. My assumption is that the RDS role may be too much for this micro instance to handle, and currently, changing to another size instance is not an option (it may be possible later if we were to receive enough funding). This leads me to the following questions: 1) Is it a sensible assessment to assume that it is the RDS role is slowing things down, or are there other things that I could look at to speed it up? We are talking about a machine with ~600MB of memory. 2) If I revert back to the pre-RDS role, is there any legitimate way (in terms of purchasing RDS licenses) to get more than 2 concurrent desktops? I did read this, and am not questioning that the answerer is knowlegeable; but someone else may have some other experience. I am also making it clear that we want to do this in a legitimate way. Thanks in advance for any assistance that can be provided! EDIT: if it is helpful in answering the question, the application in question is a Lotus Approach database. Also, I am asking this from a technical perspective: not a legal one. I want to know if it is possible to install valid licenses without the RDS role.

  • How to perform this Windows 7 permissions change on many files via GUI or command line

    - by hippietrail
    After using my external hard drive on another Windows 7 computer to tweak photos with Windows Live Photo Gallery then upload them to Facebook I found the modified images were now not visible on the original Windows 7 computer. I'm not sure if the things I tried to get it working subsequently changed anything, but I do know this is the sequence of actions that makes the permissions of the modified files match those of the unmodified files: Right click on broken image file, select "Properties" On the "Security" tab press the "Advanced" button In the "Permissions" tab press the "Continue" button with the shield icon on it Tick the box marked "Include inheritable permissions from this object's parent Click the "Remove" button to remove the only current entry "Type: Allow, Name: Administrators (XYZ\Administrators), Permission: Full control, Inherited From: OK on the "Permissions" tab. OK on the "Security" tab. Now this same procedure does not work at the folder level. It results in "access denied" dialogs. I'm looking for some way to perform this exact modification on all the images I edited on the other computer. I'm happy to use the Windows GUI in Explorer or any other included tools. I'm happy to use the Windows command line. I'd prefer not to use a third-party tool since I'd have to be satisfied it's not doing anything else. I'm not looking for a different way to change permissions to other settings to make an external drive full of photos editable on multiple computers. At least not in this question.

  • Can a OS be copied from one hard drive to another and still boot?

    - by AlexMorley-Finch
    Background My computer gets stuck on the make and model screen after the BIOS screen, aka the Toshiba screen. After some research I've realized that the problem is the hard drive. I'm using an old 250gb model that USED to be used for backup purposes, however I loaded windows 7 ultimate onto it This hard drive has trouble getting up to full RPM therefore cannot boot correctly until its warmed up. meaning that my pc needs to be restarted several times before it boots (once it took my 13 reboots to get my pc on!) From my research its either that, or lack of power supply, and I've tried multiple PSUs. Question I have my OS and all my files on this 250gb HDD... If I were to literally open the explorer, and copy EVERYTHING (including hidden files obviously) from this 250gb, to a spare 500gb I've got knocking about... Will it boot if I just copy everything? I cannot be bothered to load another OS onto my PC so if there is a way I can just copy the existing one over from one HDD to another and have it boot normally. This would be epic! I've heard about HDD cloning software. But before I purchase and/or download this software, I need to know if i can just copy the OS over through the windows explorer

  • Linux Centos 6 becomes unavailable from time to time - OS&network issue

    - by adoado0
    I am encountering following problem. There is one server (DL160 G5) running Centos 6.3 with default kernel 2.6.32-220.2.1.el6.x86_64 - at this point I'd like to add that issue appeared also at older version - 6.1 and older kernel (do not remember exactly which version). There is cPanel installed and from time to time it becomes unavailable (network connection). What I've checked is (via KVMoIP): load average is completely normal it does not lack memory or disk space when problem occurs no console notifications checked all access logs and there is no sign that it can be caused by a client script cannot even access local interface (127.0.0.1) or main IP address running tcpdump I can only see packets arriving to server - no responses all services seem to be running properly (mail,sql,http,ssh) checked crontab and all clients' crontabs too network port utilisation is low ( up to several Mbits) arriving packet rate is low - hundreds per second (according to tcpdump) console (via kvmoip) works fine, no lags there is no conntrack at this server there is no ipv6 at this server flushing iptables, unloading modules does not resolve problem restarting network does not resolve problem, no errors appear it also occurs when two sepearate networks are configured (and multiple gateways) as well as one IP, one default gw and one network is configured - so it seems network configuration independent it seems to repeat randomly (load,packet rate,bandwith usage,load independent) checked server with different rootkit detection tools - it seems to be clean server has been rebooted, it did not change anything there are no interface errors it apperas randomly can be once a week or several times per day It usually works fine after 1-15 minutes. What I can also check? It is definitely OS issue - there is traffic at interface only in one direction when problem occurs, can not even ping loopback. Any ideas? Recommended checks? Anything I did not checked above.

  • Synchronize folder on network, preserving hard links

    - by Waleed Hamra
    I have few computers using Windows XP Pro. I want to synchronize/back a folder from one machine, to another one. This far, It's a simple problem, and I've used FreeFileSync for such operations, with very satisfactory results. But, this all changes when hard links come into play. Today's folder contains lots of hard links, using such backup programs will result in hard links being treated as multiple files, and copied as such, greatly increasing folder size on destination, and defeating the purpose of using all these hard links in the first place. It gets more complicated when we take into consideration the fact that network shares on Windows DON'T expose hard linking facilities, meaning that running a hard-link-aware tool like rsync using --hard-links will be of no use. So my question, how can i backup my folder to the other computer, while preserving hard links? I don't mind installing 3rd party tools to do it, as obviously, the standard windows shares approach won't work... I am guessing there might be some tool that can be installed on both machines and works in a server/client mode? anyone has any idea how to do this?

  • Separate domains vs. one domain with alias-domains

    - by Quasdunk
    I have tried to ask this question a few days ago but I'm afraid it was not clear enough, so here's another try. I have set up a LAMP-server using ISPConfig 3 for the administration. PHP is running over Fast-CGI. I have several domains, like my_site.com, my_site.net and my_site.org, but they all point to the same application/website. Each domain has its own web-root-folder and is running under its own user. The application itself is in a common directory which is owned by another user, like so: # path to my_application (owned by web1) /var/www/clients/client1/web1/web/my_application/ # sym-link to my_application from my_site.com-web-root (owned by web5) /var/www/my_site.com/web -> /var/www/clients/client1/web1/web/ # sym-link to my_application from my_site.net (owned by web4) /var/www/my_site.net/web -> /var/www/clients/client1/web1/web/ With a setup like this I have encountered a few problems concerning the permissions when performing filesystem-operations with PHP. For instance, if the application is called via my_site.com, the user web5 is trying to write something to the application-folder. But the application-folder is owned by the user web1, so web5 is not allowed to write there. As far as I unterstand, this is how Fast-CGI works. After some research and asking a few people, the solution seems to be to break it all down to one domain (e.g. my_site.com) and define the other domains (my_site.org, my_site.net) as alias for this one domain. That way, there would be only one user who has all necessary permissions. However, this would mean that we'd have to buy a multidomain SSL-certificate - but we already have an SSL-certificate for each domain. We were able to use them with our previous provider (managed hosting), and there we also had only one web-directory and multiple domains. So if this was possible, I wonder: Is putting all the domains together into one v-host with one main- and several alias-domains the right approach in this case? Or may I have misunderstood something?

  • How do you update without cutting off users?

    - by Griffin
    I searched around and I was surprised that I couldn't find an answer to this question. My assumption is that you have multiple servers. Normally they both will be doing their specific take (for the rest of this I will assume a simple website). Now lets say server A & B need updates. Do you update server A while server B keeps pushing out the webpage and then when server A is okay you update server B? This seems like it would work in small scale but seems horrible in large scale due to the fact that you'd need twice the power that you normally have. When dealing with a large number of servers do you update small sections at a time? I thought the problem with this would be if server A can't work alongside server B C D E or F any-longer that's not that bad. But when you start updating you slowly lose this small percentage. What is the proper way to deal with updates like this?

  • linux shutdown hang with wifi cifs mounts

    - by Sirex
    Since fedora 15 (and now with 16) it seems that wireless clients take a long while to shutdown when they have network filesystems mounted at shutdown time. I've pushed out a cifs mount via puppet, and all clients have it, including those on wireless. If say a laptop is on a wired connection it shuts down just fine, but if its on the wifi at the time (and no wired connection) it'll hang at the fedora f logo. I'm not sure if its indefinite or just a really long while, but ill give it a test when i shut this machine down in a second. Needless to say its pretty annoying, so is there a way of causing the machine to shutdown even if network connectivity has been lost at unmount time, -- or an official way to reorder events so the wireless card is kept up until after the unmount happens during the shut down process (short of writing a custom script for shutdowns which is a bit of a kludge) ? It does this on multiple machines, and all started doing it when we went from fedora 14 to 15. It was such an obvious issue i'd kind of assumed someone must have reported it or there was an easy fix, but i've not discovered anything yet. Additional info: I can confirm that manually unmounting the mounts then shutting down (sudo shutdown or the xfce shutdown button) will shutdown just fine, it only hangs if the mounts are still mounted The puppet config that sets the mount looks like this (now with the _netdev entry that is indeed pushed to clients successfully, but makes no difference): file { "/mnt/share": ensure = directory,} mount { "/mnt/share": atboot = true, ensure = mounted, remounts = false, fstype = cifs, device = "//srv/share", options = "user,gid=shareusers,uid=${user},file_mode=0700,dir_mode=0700,credentials=/root/.smbcreds,_netdev", require = [ File["/mnt/share"], Group["shareusers"] ], } }

  • How to always show titles on Windows 7 Taskbar thumbail preview?

    - by Cooper
    I often use the Win+n shortcuts to 'alt-tab' between windows of pinned application (i.e. Win+2 to basically 'alt-tab' multiple putty windows, where putty is pinned as app #2 on the taskbar). The Win+n always pops up the thumbnail previews of all the windows, but sometimes it shows window titles above the thumbnail, sometimes it doesn't. Is there any way to always show the titles (i.e. registry setting?)? For putty sessions this would be especially nice, as the title contains the hostname, and the thumbnail is too small to determine what host that window is for. I've noticed that the titles usually show up with there are more than ~4-6 windows of that pinned item open - but the number seems to vary - is there a threshold setting for this? Update: So I just noticed the titles show up whenever the taskbar buttons combine, which varies based on how many windows from other apps are open... So I'm now looking for a way to combine buttons (but I'd like to keep labels, so the options in the 'Taskbar and Start Menu Properties' are close, but probably finding the registry settings behind should do it.

  • Suspected Corrupted Windows 7 MBR?

    - by AridDecay
    So, this may not be the correct place to put up my question, but i'll give it a shot. I'm having an issue repairing this computer. It was brought to me with the described issue of 'Not turning on' Later, I found that it would come with the error of 'No boot sector found on internal hard drive.' I assumed it was an MBR issue due to a virus or cutting a Windows update short. I booted into my trusty recovery enviroment and ran bootrec.exe /FIXMBR and restarted -- No luck I started to think (After multiple attempts to get the MBR sorted out, including creating a new boot sector) that the Hard-drive was possibly starting to cave in on itself, so I booted into a linux bootable CD and went to check the SMART data. Odd, say's it's inaccessible. That seems odd to me, considering it's a newer (two years old or so) Windows 7 computer. All new Hard-drives have SMART. So, I checked the BIOS. No mention of SMART anywhere. Greaaaat. I decided as a last-ditch effort to switch the hard-drive type to ATA in the BIOS (God knows why, I was getting frusterated) instead of AHCI. VOILA! It actually attempts to boot, gets halfway through the little windows animation, does an incredibly (Half a second) quick BSOD, and shuts down. Does anyone have ideas on what's going on here? I'm at my wits end.

  • What is the risk of introducing non standard image machines to a corporate environment

    - by Troy Hunt
    I’m after some feedback from those in the managed desktop or network security space on the risks of introducing machines that are not built on a standard desktop image into a large corporate environment. This particular context relates to the standard corporate image (32 bit Win XP) in a large multi-national not being suitable for a particular segment of users. In short, I’m looking at what hurdles we might come across by proposing the introduction of machines which are built and maintained by a handful of software developers and not based on the corporate desktop image (proposing 64 bit Win 7). I suspect the barriers are primarily around virus definition updates, the rollout of service packs and patches and the compatibility of existing applications with the newer OS. In terms of viruses and software updates, if machines were using common virus protection software with automated updates and using Windows Update for service packs and patches, is there still a viable risk to the corporate environment? For that matter, are large corporate environments normally vulnerable to the introduction of a machine not based on a standard image? I’m trying to get my head around how real the risk of infection and other adverse events are from machines being plugged into the network. There are multiple scenarios outside of just the example above where this might happen (i.e. a vendor plugging in a machine for internet access during a presentation). Would a large corporate network normally be sufficiently hardened against such innocuous activity? I appreciate the theory as to why policies such as standard desktop images exist, I’m just interested in the actual, practical risk and how much a network should be protected by means other than what is managed on individual PCs.

  • Export-Mailbox - fails with large folders

    - by grojo
    I am trying to move messages from a rather large mailbox to an archive mailbox. However I run into errors all the time. the command I am executing is Export-Mailbox -Identity MAILBOX_FROM -TargetMailbox ARCHIVE -TargetFolder ARCHIVE_FOLDER -StartDate 2009-02-01 -EndDate 2009-02-28 -DeleteContent -Confirm:$false I can copy/move some messages, but run into frequent "an unknown error has occurred" (statuscode -1056749164) I run the console as administrative user, and all permissions are set right, as far as I can tell. I've restricted the start and end dates in case the number of messages moved/deleted should create problems. Anything I am missing in my setup? Corrupted messages? Over-limit message sizes? Update: What I've learnt so far, is that folder with more than approx 3000 messages will generate errors. If mail retention is set (default 30 days), Export-Mailbox will scan all messages whether these were deleted in previous runs or not, and date restriction to limit number of messages will not work. To avoid errors, I've switched off deleted message retention for the mailbox, and moved the messages from one large folder to multiple folders, and moved these one by one...

  • What mobile phones are viable for a "nerdy" person? [closed]

    - by Blixt
    This community wiki is for determining a list of good mobile phone choices if you are "nerdy" (definition follows.) As a point of reference, the almost two years old N95 8GB will be used. Mostly because that's what I can most relate to since I've had it since it came out. Today, iPhone and other modern mobile phones really out-shine it in usability and interface. However, it still does everything I want it to do (and here's the definition of "nerdy"; modify as needed): Syncs contacts, calendar, tasks and mail in the background Can run multiple installable applications in the background (Google Maps with Latitude, for example) Good amount of space for music etc. Lets you develop your own little toy applications (Python; not to mention it can also run an Apache server with a public URL!) Tethering! Supports Flash (maybe not very important, but it has its uses) Has a manufacturer that believes in the nerdiness! (The people at Nokia Labs make lots of cool stuff and share early versions with the community and are generally open) A high resolution screen (at least 320x240) Special hardware features such as an accelerometer and GPS What's missing from the N95 8GB but still qualifies as good, "nerdy", qualities: 7.2 Mbit/s (or faster) internet through HSDPA or HSPA+. A good web browser that can do most of the stuff a desktop browser can (especially render sites properly and run JavaScript correctly) Touch (especially multi-touch) More special hardware features such as a compass Intuitive and fluent user interface (Shiny stuff) Ability to configure it to trust root certificates of my own choice A processor fast enough to run Quake 3! =)

  • Apache, logerror and logrotate: what is the best method?

    - by OlivierDofus
    Here's a vhost example of my sites: <VirtualHost *:80> DocumentRoot /datas/web/woog ServerName woog.com ServerAlias www.woog.com ErrorLog "|/httpd-2.2.8/bin/rotatelogs /logs/woog/error_log 86400" CustomLog "|/httpd-2.2.8/bin/rotatelogs /logs/woog/access_log 86400" combined DirectoryIndex index.php index.htm <Location /> Allow from All </Location> <Directory /*> Options FollowSymLinks AllowOverride Limit AuthConfig </Directory> </VirtualHost> I've got 12 sites running now. This gives something like: [Shake]:/sources/software/mod_log_rotate# ps x | grep rotate /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/error_log 86400 /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/error_log 86400 [snap (as many error_log as virtual hosts)] /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/access_log 86400 /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/access_log 86400 [snap (as many access_log as virtual hosts)] grep rotate [Shake]:/sources/software/mod_log_rotate# !!! I've been looking everywhere but I've only found mod_log_rotate. The "little" problem is that the author (very good C developper) explains: "Unfortunately Apache error logs are handled in such a way that we can't work the same log rotation magic on them. Like transfer logs they support piped logging though so you can still use rotatelogs for them. " So my question is: what would be the best way to handle multiple logs? If I just do a very classical log and I use the system's "logrotate" program couldn't this be a good deal? How would/do you deal with that? Thank you!
