• Why does the IIS_IUSRS user need read permission on the ApplicationHost.config file in my Exchange 2010 OWA environment?

  - by CrabbyAdmin

  Previously I was experiencing issues where users in my Exchange 2010 environment would periodically receive an error stating: The custom error module does not recognize this error. However, following the advice of a thread I read somewhere, I granted the computername\IIS_IUSRS user Read permissions on the ApplicationHost.config file in the OWA environment. After making this change, the problem has not yet resurfaced. However, I'm not satisfied to simply settle for the fix, I'd like to understand why it worked. So can somebody please tell me why does this user need read permissions on this file and why would that have resolved the issue?

• ESXi and Windows Server CPU parking

  - by Chris J

  For those that don't know, CPU parking is a feature in recent Windows Server releases that allows Windows to pretty much drop a CPU core to zero use, and having nothing use it. It's been introduced as a power-saving measure. There's more detail about it here, amongst other places. However what I'm curious about is whether this matter on a virtualised guest - or is CPU parking more of a hindrance than a help, given that the physical CPUs are managed by ESXi, not Windows, and that a parked CPU is less likely to deal with traffic unless the scheduler deems there's enough work to unpark the CPU? I've not found anything about this - I do suspect it will be very much based on a given workload, but I've not seen any discussion (unlike, say, whether hyper-threading has any effect, which seems to be discussed regularly). Whilst I do understand the "test with your workload" I was wondering if there was any advice/guidelines out there that I've missed.

• w2k3 chkdsk errors as vmware 1.8 guest

  - by Sean Kirkpatrick

  We have two Dell servers (CentOS 5.x) hosting a variety of VMs including 3 W2K3 and 1 W2K servers as guests as well as a handful of other Linux guests. Each Windows VM has 2 drives, C: and D:. on 2 of the W2K3 and the W2K boxes we have recurring errors appearing on a daily basis as reported by CHKDSK. We'll run CHKDSK /f and reboot all affected machines and the errors are reported as fixed. The next day CHKDSK will report the same errors. None of the linux guests nor either host report errors when the are rebooted. The RAID controllers are not reporting errors. We're beginning to think that these are phantom errors somehow, but I'm not willing to go to the bank on that just yet. Anybody have similar experiences or advice? Thanks! Sean

• Can't figure out error in Cisco ASA log "regular translation creation failed for icmp ..."

  - by Martijn Heemels

  Every few seconds our new Cisco ASA 5505 firewall is logging errors that I can't figure out with my limited Cisco experience. Severity Date Time Syslog ID Source IP Destination IP Description 3 Mar 25 2010 17:21:14 305006 8.8.8.8 regular translation creation failed for icmp src inside:10.10.0.200 dst outside:8.8.8.8 (type 3, code 3) 3 Mar 25 2010 17:18:37 305006 8.8.4.4 regular translation creation failed for icmp src inside:10.10.0.200 dst outside:8.8.4.4 (type 3, code 3) The logged inside IP is our internal DNS resolver, and the outside IP's are Google's public DNS servers. ICMP Type 3 Code 3 means "Port Unreachable" Our "outside" interface has a fixed IP and our "inside" interface is in the 10.10.0.0/16 subnet. The 'Inspect DNS' Service Policy is enabled, with the preset DNS inspection map. Furthermore there's an ACL that allows all inbound ICMP on the "outside" interface. I've spent hours trying to figure this one out, so any and all advice is welcome!

• Google shows subdomain of main site instead of add on domain URL [closed]

  - by Welsher

  I have my host (lunarpages) set up with a few add on domains to my main account. These show up as sub-domains of my main account, but they can be reached by using the new domain I've created. So: subdomain1.domain.com -- www.mynewsite.com subdomain2.domain.com -- www.myothersite.com etc. The problem is, mynewsite.com shows up in google with that domain, but myothersite.com shows up with subdomain2.domain.com. I don't have a clue what might be causing this to happen. If anyone has an advice or can point me in the right direction, I'd really appreciate it! Thanks.

  - by techastute

  Problem Got java.io.IOException: Too many open files in solr indexing through jenkins. Did some googling and found we have to set the ulimit for the box in where we are running the job. So set the ulimit in a linux box with spec Linux x86_64 GNU/Linux in both of the following fashions ulimit -n 1000000 /etc/security/limits.conf userx soft nofile 1000000 userx hard nofile 1000000 Given userx is the user through which the jenkins job is being executed. when doing ssh to the box as userx manually through terminal and check ulimit -n am getting 10000000 Question But when executing the same ulimit -n through a jenkins job, only getting 1024 which is the default. Any advice would be much helpful?

• Configuring RAID1 on HP Proliant Microserver N54L / Ubuntu 14.04.1 LTS [duplicate]

  - by Chris Beach

  This question already has an answer here: Cant find my harddrives in ubuntu installation? 2 answers I've bought a N54L and fitted two 3GB drives. Keen to get set up with RAID1. BIOS: SATA controller mode set to "RAID" RAID Option ROM utility: both physical drives set up as one logical drive When I came to install Ubuntu (14.04.1), both drives appeared during the setup process. I was only expecting to see the logical drive, although I'm a complete novice with RAID. I've read that the HP Proliant Microservers don't have "proper" RAID support, and require some kind of driver to be installed. I've tried a few HP utilities from the following apt repo: deb http://downloads.linux.hp.com/SDR/repo/mcp wheezy/current non-free On installation, most say "server not supported" Would appreciate your advice.

• MySQL replication Slave_IO_Running: No

  - by Christy

  Hi all, I have two servers that I am trying to get replication of one database between. I found a setup guide on sourceforge that I followed and I have tried various other settings since then, but no matter what I do, when I start the slave, the 'Slave_IO_Running' setting is always No.... I have no idea why or what to look at, any suggestions are appreciated. The slave setup was: CHANGE MASTER TO MASTER_HOST='myserver.mydomain.net', MASTER_USER='slave_user', 'MASTER_PASSWORD='mypassword', 'MASTER_LOG_FILE='mysql-bin.000011', MASTER_LOG_POS=1368363 (last data from today, trying to do setup again. I deleted and recreated the database on the slave from a new dump and tried to redo the setup.) I have slave_user setup for %, localhost, and the specific IP of the slave computer but nothing seems to be working... Thanks in advance for any advice or suggestions

• Copy Content from Sharepoint2007 to another Sharepoint2007

  - by Beuy

  Hi There, I have a Sharepoint 2007 web farm installation with two site collections, one is a blank site and the other is a migrated Sharepoint 2003 site collection. I want to move some specific content from the migrated 2003 collection to the 2007 collection, however I also want to change the path of where it exists, an example is that in the migrated 2003 collection HR is under Admin HR, in the 2007 collection I want HR to appear before Admin. I've looked around but haven't found a lot of information regarding how to move specific content between sites, any advice or help is greatly appreciated.

• Minimizing SQL transaction log file size on developer box running simple recovery model

  - by Anders Rask

  We have alot of SQL servers on development environment where we never take backup of the databases (TFS for code is enough). The (SharePoint) databases are all set to simple recovery model, but the log files, especially for the SharePoint configuration database is growing quite large and filling up our data drive on the SQL server. Since these log files are never used for anything, i would like advice on how to best minimize the size of these log files -or even disable them if possible. I'm not completely sure why the log files grow so large even on simple logging (checked for long running transactions (DBCC OPENTRAN) but found none). I guess the reason for the log files not being truncated is, that we dont take any backups, and hence Checkpoints arent reached. The autogrowth for log files are set to autogrow by 10% restricted to 2 gb, so i guess that is why Checkpoint (70%) arent reached here either. What would be the be best strategy to keep log files small (best case 0) without sacrificing performance (eg VLF fragmentation)?

• Optimum no./size partitions for Windows 7

  - by Pat. Mitchell

  I plan to install a 500GB drive in my notebook (HP dv2613tu/1.5gHz/4MB RAM) and need advice about optimum size and number of partitions to create. Ideally looking for the following: OS (Windows 7 Ultimate) Swap file Applications Data ??? As a long time Mac user I'm not nearly as informed about Windows. I could leave everything as a single partition, but am seeking maximum performance and efficiency from my system (which won't be changing anytime soon). So, would separate partitions help with this aim? And given my usual habit of accumulating stuff, I want to reserve most space for Applications and Data. I've also set myself a project over the next couple of years of digitizing the whole of my 35 y.o. collection of slides and photographs from my travelling days. Thanks. Pat. Mitchell

  - by user34300

  I have a Sony Vaio TZ2 laptop here and I'm trying to install Windows XP SP3 on it. Everything works fine except of the integrated camera which is supposed to be a USB device but is absent in the Devoice Manager. I've read that it is important in what order you install drivers when you downgrade this Vista preinstalled model to Windows XP so I repeated once again the installation with the correct order by still had no luck with the camera. Can someone give me an advice on how to woke up this camera? Thanks!

• windows server 2008 web edition cant change permissions

  - by minus4

  hi there, Im used to using windows server 2003 but decided to get a Vista web edition for IIS7 and to run our MVC applications on. I have installed copSSH that i use for SFTP, and when i upload my files i am unable to change persmissions or take ownership or anything when logged in as an administrator. when i try to go to permissions i get: The permissions on uploads are incorrectly ordered, which may cause some entries to be ineffective. and all permissions are the grayed out. i have tried to use icacls to reset ownership and also tried to give myself full control through icacls however all attempts are met with a access is denied message and failed processing 669 files. all i wish to do is set up write and delete permissions on an upload folder for a CMS systems admin area, but i am a week into looking into this and i am still no wiser. Please could someone give some sound advice so i can get this running smooth thanks p.s i have added the copSSH notes as i think that when i SFTP the files to the server, this may somehow have some involvement in messing up permissions

• Sony Vaio Hard Drive replacement won't boot

  - by AJ Bovaird

  I'm working on a Sony Vaio VGN-CR120e. I've cloned the original SATA 1.5 drive with Norton Ghost on to 2 new hard drives, the second of which is a Seagate 7200.4 320Gb 7200 RPM, with the jumper set to limit to SATA 1.5. (The first drive is a WD Scorpio Black 320Gb 7200RMP, which has no SATA 1.5 override support). Neither of the cloned drives will boot - I immediately get a BlackSOD saying: "Windows failed to start blah blah blah" "File \Windows\system32\winload.exe" "Status: 0xc000000e" "Info: The selected entry could not be loaded because the application is missing or corrupt." I've done this hundreds of times on other PC's, and this is the first time I've encountered such an error. Does anyone have any suggestions or advice on how to proceeed, as I would rather not reinstall Vista unless absolutely necessary.

• configure spam assassin to delete all spam above a score domain wide and override individual settin

  - by Marlon

  Okay, so this is my scenario and what I want to try and do. I maintain a Red Hat email server running qmail and spamassassin. I have a domain that has well over 100 email account each with individual settings for spam scores and, whether or not to delete email incoming mail deemed spam. What I want to accomplish is to change all those email email accounts to say a more stringent spam score value, AND to enable the deletion of email immediately as it flagged as such, for EACH AND EVERY email box. In short, I want to be able to override a user's individual settings spam settings, with my own. Short of tediously going into each and every email box one by one, is there an way to do this all in one fell swoop? Any advice would be greatly appreciated! :-)

• Linode - Centos 5.5 -

  - by Marcus West

  Hi, I rather foolishly undertook to install a control panel on a Linode. I opted to use CentOs 5.5 (either ordinary or 64 bit) but I am like a monkey playing a reward game... I have some idea of what I am doing, but not enough.... In certain areas I am hopeless....do I install Webmin/virtualmin, or ISP Config..... ISP Config 2 or 3? I would employ someone to help, but how do i find the right person? Where can i learn the ropes on all this? There seems to be no systematic training, and even when I try to research college courses in the UK, I am none the wiser as to where I could go to learn how to run a Linux server..... Has anyone any pointers? Right now I am looking at th esecurity aspects of the server.....rkhunter , denyhosts etc... Any advice on installing and maintaining these things? Cheers marcus

• Accessing apache on virtual pc

  - by Rick Hensly

  I am using a virtual pc to test my website. I can access all my webpages on the virtual pc. However, images don't load correctly. I can browse to my images folder and view all of them. However, if I click an image it will not load, and the apache log shows the virtual pc's ip trying to view the image: 192.168.0.55 - - [25/Jun/2009:20:10:41 -0400] "GET /images/pic.png HTTP/1.1" 302 220 Now, if I refresh the page it loads. 192.168.0.55 - - [25/Jun/2009:20:10:51 -0400] "GET /images/bg.png HTTP/1.1" 200 214 Also, images won't load in html or css. It seems like a redirecting problem or something, but I have no clue how to fix it. Thanks for any advice

• Why don't I have write permission to my vmware virtual network device?

  - by Robert Martin

  I want to allow my VMWare machine to force the virtual network it's on into promiscuous mode so I can play around with honeyd. I received an error message that told me to go to http://vmware.com/info?id=161 to allow this behavior. Based on their advice, I did: $ groupadd promiscuous $ cat /etc/group | grep promiscuous promiscuous:x:1002:robert $ usermod -a -G promiscuous robert $ id robert uid=1000(robert) gid=1000(robert) groups=1000(robert),....,1002(promiscuous) $ chgrp newgroup /dev/vmnet8 $ chmod g+rw /dev/vmnet8 $ ls -l /dev/vmnet8 crw-rw---- 1 root promiscuous 119, 8 2012-03-29 10:29 /dev/vmnet8 Looks like I gave RW permission to the promiscuous group, and added myself. Except that VMWare still gives me an error message that says I cannot enter promiscuous mode. To try out the group thing, I tried: $ echo "1" >/dev/vmnet8 bash: /dev/vmnet8: Permission denied That really surprised me: It makes me think that I still haven't properly given myself the correct permissions... What am I missing?

• Enable SMB file sharing on OS X - "Incorrect Password"

  - by Tim Robinson

  I have a Mac running Snow Leopard connected to an Active Directory domain. I can share folders on the Mac and view files from Windows without problems. When I try to enable my Mac account for write access through System Preferences, I'm prompted for my account's password. Even though I'm entering the right one, I get an "Incorrect Password" response. The same process works fine for the local Mac administrator account; it's the Active Directory account I'm having problems with. I followed the advice on this page on apple.com without success: (I used the Mac to reset my domain password, and re-created my login keychain) If you want to use a user account that existed before you installed Mac OS X 10.3 (Panther), you may need to reset the password for the account using Accounts preferences. Can anyone suggest what might be wrong? Until I fix this I can't write to my Mac file share from Windows.

• how to multi-boot/upgrade linux from LVM-based partition

  - by kenny-bobby

  i currently have FC3 linux which installed itself on the hard disk using LVM partitioning, so it is basically all one big partition. i would like to try some other distributions and upgrade to something newer, but don't want to lose my current capabilities and data files, and i know nothing or less about LVM. Is it possible (and if so an example would be nice) to install a non-LVM-based distribution on the LVM disk and have multi-boot options? Or do i have to start over new and drop the LVM? My guess is that i should save my /home (data files and .rc files) on a backup device first, then somewhere/somehow create a new partion for installing another distribution. Any LVM experts out there that have tried anything like this--well i sure could use some pointers and advice...

• Why is this PHP loop rendering every row twice?

  - by Christopher

  I'm working on a real frankensite here not of my own design. There's a rudimentary CMS and one of the pages shows customer records from a MySQL DB. For some reason, it has no probs picking up the data from the DB - there's no duplicate records - but it renders each row twice. The page PHP is viewable at http://christopher.pastebin.com/DQkjjG3s (attempted to include in this post but it was horribly mangled, think it's important to have it all in context). I'm not the world's best PHP expert but I think I can see an error in a for loop when there is one... But everything looks ok to me. You'll notice that the customer name is clickable; clicking takes you to another page where you can view their full info as held in the DB - and for both rows, the customer ID is identical, and manually checking the DB shows there's no duplicate entries. The code is definitely rendering each row twice, but for what reason I have no idea. All pointers / advice appreciated.

• RRAS VPN Server on Windows 2008 Behind NAT

  - by Chris

  Ok, so I have kind of a funky setup, let me see if I can describe it. I have a single VMware host with a public IP address 74.xx.xx.x Inside that host, I have 3 VM's Web Server - 1 NIC - 192.168.199.20 SQL Server - 1 NIC - 192.168.199.30 RRAS/VPN Server - 2 NICs 192.168.199.40 & 192.168.199.45 Due to Limitations of my ISP, all of the VM's are connected to the host VIA NAT. I have NAT setup for the webserver so all incoming requests on 74.xx.xx.x via port 80 route to 192.168.199.20. This works fine. Now I want to set up a Windows 2008 VPN server inside this NAT network and forward the correct traffic to it. My questions are as follows? What are the TCP/UDP ports that i have to forward? What special configuration is needed on the server and clients since this is behind a NAT Any other advice would be wonderful.
