• Mail Enabled Sharepoint 2010 Loop Detected

  - by vlannoob

  I have setup a small Sharepoint 2010 deployment and it is working fine, for now. I have run through one of the more popular step by step guides to mail enable the install and what I have is internal and external mail going to my mail enabled list hitting my Exchange 2010 server (on another Win2k8R2 box) and sitting in the submissions queue with a Loop Detected error and they progres no further. Everything appears OK as per the guide. I have setup an SMTP role on the Sharepoint box, as per the guide. I have setup a new Send Conenctor on the Exchange 2010 server, as per the guide. Any ideas on troubleshooting here?

• Top ten security tips for non-technical users

  - by Justin

  I'm giving a presentation later this week to the staff at the company where I work. The goal of the presentation is to serve as a refresher/remidner of good practices that can help keep our network secure. The audience is made up of both programmers and non-technical staff, so the presentation is geared for non-technical users. I want part of this presentation to be a top list of "tips". The list needs to be short (to encourage memory) and be specific and relevant to the user. I have the following five items so far: Never open an attachment you didn't expect Only download software from a trusted source, like download.com Do not distribute passwords when requested via phone or email Be wary of social engineering Do not store sensitive data on an FTP server Some clarifications: This is for our work network These need to be "best practices" tips for the end-user, not IT policy We have backups, OS patches, firewall, AV, etc, all centrally managed This is for a small business (less than 25 people) I have two questions: Do you suggest any additional items? Do you suggest any changes to existing items?

• Secure PHP environments with PHP-FPM and SFTP

  - by pdd

  I'd like to set up secure environments for a small number of untrusted PHP websites on a Debian server. Right now everything runs on the same Apache2 with mod_php5 and vsftpd for administrative file access, so there is room for improvement. The idea is to use nginx instead of apache, SFTP through OpenSSH instead of vsftpd and chrooted (in sshd_config), individual users for each website with their own pool of PHP processes. All these users and nginx are part of the same group. Now in theory I can set 700 permissions on all PHP scripts and 750 on static files that nginx has to serve up. Theoretically, if a website is compromised all the other users' data is safe, right? Are there better solutions that require less setup time and memory per website? Cheers

• Changed folder contents not updating in Finder (OS X 10.8)

  - by speedofmac

  I've been having this problem for a number of days now. When I update the contents of a folder using terminal commands, by decompressing archives, or by using "Save As", the affected folder often fails to reflect these changes. Sometimes it takes quite a while for any files to be shown, even if the total size of the folder is fairly small (< 10 MB). I'm running an '09 MacBook Pro 13", so it isn't the newest system, but it certainly has enough oomph to display a list of files in a folder. Does anyone know what might be causing this?

• Run a MongoDB configuration server without 3GB of journal files

  - by Thilo

  For a production sharded MongoDB installation we need 3 configuration servers. According to the documentation "the config server mongod process is fairly lightweight and can be ran on machines performing other work". However, in the default configuration, they all have journalling enabled, and with preallocation this takes up 3 GB of disk space. I assume that the actual data and transaction volume of a config server is quite small, so that this seems a bit too much. Is there a way to (safely!) run these config servers with much less disk use for the journal? Do I need journalling at all on config servers? Can I set the journal size to be smaller?

• Best way to backup and restore millions of files

  - by bongo

  Hi, I'm facing a rebuilding of the volume on which I host the mail storage (kerio mailserver, which uses maildirs). I need to backup and restore as quick as possible the 3.5+ millions (for about 600GB) small files of the store directory. It takes more than 12 hours via rsync to a NFS share, but I also have a 1TB firewire 800 raid1 disk that I can use (from some preliminary tests it's faster). I'm working off a XServe intel. What is the fastest way to do it? Rsync? Finder copy? tar?

• Firefox "auto-complete" is very slow

  - by netvope

  Firefox version: 3.6 My places.sqlite is rather big (114MB, after being optimized by SpeedyFox.) If I turn on auto-complete, it may take 1 or 2 seconds for Firefox to accept a newly typed URL. To reproduce the issue: Type a URL into the URL bar, press enter. Nothing happens, and Firefox consumes 100% CPU (actually 50% of 2 cores) for 1 to 2 seconds Then Firefox start the network connection and load the webpage. Since it consumes 100% CPU, I don't think the bottleneck is the disk. I have some experience with SQLite and I know a 100MB DB is very small. To achieve the delay Firefox must be doing some expensive processing or inefficient queries. The issue does not appear if: auto-complete is turned off, or the URL is frequently used, or a new profile with no history is used Does anyone have any idea how to solve the problem? Should I file this as a bug? I don't want to give up my 100MB history, but I don't want to give up auto-complete either :)

• Additional mailboxes in Outlook 07 SP2

  - by Nick

  I have had my Outlook 2007 open additional mailboxes via the advanced account settings. After updating to Office SP2, the list of emails in the additional account still displays, but I get a message for each mailbox item: This item cannot be displayed in the Reading Pane. Open the item to read its contents. After double clicking the message, I get a small error box which displays just Cannot open this item. Unknown Error. Also, if I try to re-add the mailbox in the Advanced tab of my account settings, I get an error message The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action. However, the status bar indicates Online with Microsoft Exchange, and I can both send and receive emails from my primary account. What could be going wrong?

• Different block sizes for partition and underlying logical disk on HP Raid Controller (Linux)

  - by Wawrzek

  Following links collected in this thread I started to check blockdev and found the following output indicating different sizes for partition c0d9p1 and the underlying device (c0d9): [root@machine ~]# blockdev --report /dev/cciss/c0d9 RO RA SSZ BSZ StartSec Size Device rw 256 512 4096 0 3906963632 /dev/cciss/c0d9 [root@machine ~]# blockdev --report /dev/cciss/c0d9p1 RO RA SSZ BSZ StartSec Size Device rw 256 512 2048 1 3906959039 /dev/cciss/c0d9p1 We have a lot of small files, so yes the block size is smaller than normal. The device is a logical driver on an HP P410 raid controller, simple disk without any raid - RAID 0 on one disk to be precise. (Please note that above configuration is a feature not a bug). Therefore, I have the following questions. Can the above discrepancy in the block size affect disk performance? Can I control the block size using hpacucli?

• Can i enlarge os c drive of my windows 8?

  - by Sorgatz

  Last year I got a new Western Digital WD Blue 500GB HDD to replace my old drive. The first thing I did was to install latest Windows 8. While installing Windows 8 I created 3 partitions, C drive for the OS and others for storage. The OS partition is 120GB (which at the time I thought would be plenty big) but I'm now realizing its too small! I wonder if it's possible to re-size HDD partition without reformatting and re-install my Windows 8. So that is my question, Can i enlarge os c drive of my windows 8 without having to re-format? I've used the Norton Partition Magic and Disk Management to make this happen but there doesn't seem to be any options to make it happen. Thanks for any help you guys can give regarding my question. I've worked hard to optimize my current install of Windows 8 and would hate to start all over again.

• Automatic time tracking with central server, web reports

  - by user124209

  I need a software for automatic time tracking on Windows. With the following features: It should record time spent using the computer each day. Start time and end time. It should record what programs the employee used and total time for that program for specified period of time. It must have a centralized server that collects and stores all data. It could be a cloud server outside of a company network. It must have a web interface for viewing the monthly reports (the last but the most important requirement!). A nice feature to have would be an automatic generation of timesheets and Mac OS X support. I am looking to use it for a small team, this is not for personal use. Does anybody knows about software with these features?

• WYSIWYG editor for structured text (suitable for SVN versioning)

  - by chris_l

  I'm looking for an open source cross platform WYSIWYG editor that I can use to write documentation. I'm not looking for a web based solution - i.e. it should work without a web server, and I want to save my files directly to disk. The result could be any structured format, like Wiki markup, ReStructuredText, DocBook, or a small subset of HTML, ... But it's important, that Subversion diff can be used to see differences between the versions easily (this wouldn't work with .odt or .rtf files for example) I'm currently thinking about using Open Office, and saving the files as HTML, but is there a better solution?

• How can I download videos from this website?

  - by user82171

  I wanted to downlaod some of these short videos from chinadaily.com. For example, http://video.chinadaily.com.cn/2013/1012/1388.shtml I have tried NetVideoHunter with Firefox, which works for me for many other sites. But here, NetVideoHunter shows me very small segments of less than 200 KB and when I try to play them (in the NVH panel itself), it says 'Connecting' and then 'Stream not found'. I have seen other question on SuperUser about how to download a Flash video. The URL shows something likes this for each segment. definst/mp4:ugc/2013/1012/1762_video_9829_6_1381544755203.mp4/media_b580746_w1896927931.abst/Seg1-Frag80"http://videostream.chinadaily.com.cn:1935/app_1/definst/mp4:ugc/2013/1012/1762_video_9829_6_1381544755203.mp4/media_b580746_w1896927931.abst/Seg1-Frag80 Is there a way to download these videos? Or is this method of segmenting done to prevent downloads? Thank you

• How much should a Systems Administrator be making?

  - by Curtis

  Hello, I'm a Sys Admin for a small (but successful and growing) company (~60 employees). I've got roughly 5-6 years of actual sys admin experience, plus another 5+ years of lower level work in the industry. I'm responsible for most everything above a helpdesk level in the company (server[windows]/network[cisco]/firewall/SAN[emc] setup/configuration/maintenance/troubleshooting), lead many projects, analyze system data -- I'm sure you've heard it all before...I have a bunch of certs, most are just "nice to have", but the ones that actually apply to my role are CCNA, MSCE, VCP (VMware). If things go wrong, I'm first in line to resolve the issue. I'm not management (no one reports to me). I've seen many of these sorts of questions online before, and I know the typical response is "too many variables, depends on location, industry type" etc etc. I'm just wondering (ballpark) what I should be looking for. I've tried to give as much detail as I can, but if I'm missing something, I'd be glad to post it. Thanks anyone.

• Determining who is running with administrator rights?

  - by Alex C.

  I work at a small non-profit organization with about 55 desktop PCs running Windows XP Pro. The domain controller is running Windows Server 2003. I have a two-part question (note that I'm a bit of a newb when it comes to network administration). Part 1: Is there some simple way that I can determine which accounts are logged in with administrator rights? Part 2: Is there a way that I can remove administrator rights from users without sitting down at each individual machine? Thanks for considering my questions.

• VPN Network intermittantly fails to provide internet: What could be possible causes

  - by Jake M

  We have a small office with our own VPN setup. We occasionally experience failures in our internet connection where we cannot access the internet. Most of the time the internet connection will resume by itself(without me doing anything) after a period of time(10 mins). Would you be able to suggest possible causes of the connection failure so I can then go and run some tests? Our network architecture is like so: A 'Billion' brand router that is connected to the internet via phone cable and then connected to our Cisco Switch A Cisco Switch/Bus which is connected to all our office nodes, our external harddrive and also to our router as stated above. All connections are via ethernet cable A series of work computers(nodes) connected via ethernet cable to the Cisco switch. Our ISP is TPG Australia We have a Virtual Private Network All the ethernet cables are about 3 years old Do you think that the causes of our intermittant connection problems could be due to the following: Data collisions in the ethernet cables Old/Faulty ethernet cables Our ISP has bad service Can you think of any other causes of the problem?

• Microsoft VDI 2012 - VDI Personal collection vs Session-based deployment

  - by Vazgen

  I have a small confusion about the differences between the 2 types of set ups: When deploying using Add Roles and Features the Wizard requests to choose from one of two Deployment Scenarios: Virtual machine-based desktop deployment : Virtual machine-based desktop deployment allows users to connect to virtual desktop collections that include published RemoteApp programs and virtual desktops. Session-based desktop deployment : Session-based desktop deployment allows users to connect to session collections that include published RemoteApp programs and session-based desktops. Although this seems intuitive now, if I continue with "Virtual machine-based desktop deployment" I later have another two options when creating a collection: Pooled virtual desktop collection Personal virtual desktop collection This is where my confusion lies. What is the differences between a Session-based deployment and Virtual machine-based deployment with Personal virtual desktop collections? I'm mostly finding information pertaining to Windows Server 2008 but I know there are some core improvements in VDI 2012 so would someone please comment on that. Thank you

• IIS FTP service - download timeouts and restarts getting the data twice

  - by accel229

  We have an IIS FTP site on a Windows Server 2003 x64 machine. Application Layer Gateway service is disabled (so http://support.microsoft.com/kb/931130 does not apply). Windows Firewall service is disabled as well. Connection timeout for the FTP site (there is only one) is set to 1,200 seconds = 20 minutes. An external client can connect to the site, list directory contents and download small files. When a client attempts to download a large file (eg, if the download continues for 3 minutes, which is still under 20 minutes, but relatively long), the server sends all data, then the connection times out, the client issues REST / RETR commands attempting to restart the download since after the last byte (which I believe should succeed and receive exactly 0 bytes), and the server behaves as if the client tried to restart after byte 0, that is, it sends the entire file all over. Any ideas on how to fix this?

• ZFS: Redistribute zvol over all disks in the zpool?

  - by growse

  Is there a way in which ZFS can be prompted to redistribute a given filesystem over the all of the disks in its zpool? I'm thinking of a scenario where I have a fixed size ZFS volume that's exported as a LUN over FC. The current zpool is small, just two 1TB mirrored disks, and the zvol is 750GB in total. If I were to suddenly expand the size of the zpool to, say, 12 1TB disks, I believe the zvol would still effectively be 'housed' on the first two spindles only. Given that more spindles = more IOPS, what method could I use to 'redistribute' the zvol over all 12 spindles to take advantage of them?

• NFS failover WITHOUT DRBD?

  - by user439407

  So I am trying to set up a redundant NFS share in a cloud environment(all links internal, half gig links), and I am looking into using heartbeat for failover, but all the guides seem to be about combining DRBD and heartbeat to create a robust environment. If need be I can do that, but since my content is almost completely static, I would like to avoid the extra overhead and complexity of DRBD if possible, but still be able to fail over if one of the NFS servers fails. Is it possible to use heartbeat with NFS to achieve high-availability without using DRBD to copy the blocks? I am not married to NFSv4, so if NFSv3 over UDP is necessary, that won't be a problem(only a very small number of clients will be connecting to the share) Any comments are appreciated.

• Why use multiple partitions on a rhel server?

  - by Jakobud

  I'm about to reformat and reinstall CentOS onto an old server. The server runs on a modest 30 node small business network and has a variety of responsibilities including MySQL, a Samba share, DHCPd & SVN/Trac. The old sysadmin had this server setup with almost a dozen different partitions for various things. I'm trying to understand what the advantages of multiple partitions are as opposed to a just one filesystem at /. Speed? Flexibility? Security? It seems like if you misjudge the necessary size for any given partition and it ends up filling up too fast, it requires a sysadmin to go in and expand the partition, etc... Seems like it would be easier if everything was just one flat / filesystem. But I'm sure there are some advantages I'm not aware of. The server is currently running a handful of HDDs raided to ~2TB (raid 0).

• Win7 to Win7 Remote Desktop Not working, Xp to 7 working fine

  - by vlad b.

  Hello, I have a small home network and recently i tried to enable remote desktop for one of the pc's. I have a mix of Windows 7, Windows Vista and Xp runing alongside ubuntu, centos and others (some virtual, some real). I have a few Windows 7 pc`s that can be connected to using remote desktop from inside and outside the network (port redirects on routers, etc, etc) and some Xp ones. The trouble is when i tried to do the same thing to a Win7 laptop i discovered i can't connect to it from another win7 pc inside the home network. To sum it up Working: xp -- win7 not working: win7 -- win7 What i tried - disable and enable remote desktop (my computer - remote settings) - removing and adding users to the remote settings window - adding a new user to the machine, administrator or 'normal' user - checking the firewall settings on the machine and set 'allow' to remote desktop for both 'home/work' and 'public'networks Any tips on what should i do next? It displays ' .. secure connection' and after that the window with 'Your security credentials did not work' and it lets me try again with another user/password..

• What's the strategy to implement a "knowledge base" in my company. [closed]

  - by Oscar Reyes

  In my current work we think we can get benefit from having a knowledge base, so the next time someone has a question/problem etc, that base can be consulted and an answer will show up. Also, it will reduce the risk from having people leaving the company with the knowledge and we would have to start all over again. My question is, what strategy can we follow to implement/buy/get/build/etc this knowledge base? Are there software ready for this? Would it be better to have something build by ourselves ( we have some programmers ) This is an small company ( < 30 ) and the base should be accessible from outside the office ( when the employees are with the customer etc.) so I guess a webapp is in order.

• How to get a good current VMWare browser appliance?

  - by Brooks Moses

  I'd like to have a small VMWare virtual machine that runs a copy of Firefox, with Flash enabled. (Or some equivalently-capable browser.) I tried doing some Google searching with no luck finding good keywords, and tried looking through VMWare's "marketplace" of VMs, but all I found were things from 2006 or so. Is there a reasonably easy way to get a current one? Ideally, I'd like to just download one somewhere, but in the alternative, a quick how-to guide would be useful. I know I could go through the whole process of getting a full-Linux-install VM and setting things up, but that seems like quite a lot of trouble and ends up with a pretty heavyweight solution to the problem, so I'm hoping there's a simpler way.
