• Will adding a SSD cache device to my ZFS storage improve performance?

  - by Sysadminicus

  The server has 4GB of RAM and my zpool is made up of 15.5k SAS drives arranged like this: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c0t2d0 ONLINE 0 0 0 c0t3d0 ONLINE 0 0 0 c0t4d0 ONLINE 0 0 0 c0t5d0 ONLINE 0 0 0 c0t6d0 ONLINE 0 0 0 c0t7d0 ONLINE 0 0 0 c0t8d0 ONLINE 0 0 0 raidz1-1 ONLINE 0 0 0 c0t10d0 ONLINE 0 0 0 c0t11d0 ONLINE 0 0 0 c0t12d0 ONLINE 0 0 0 c0t13d0 ONLINE 0 0 0 c0t14d0 ONLINE 0 0 0 spares c0t9d0 AVAIL c0t1d0 AVAIL The primary use is as an NFS store for a couple VMWare ESXi servers. I can't do any "true" benchmarks because this is a production system (no budget for test systems), but using dd and bonnie++ I can't get more than ~40-50MB/s writes and ~70-90MB/s reads. It seems I should be able to do much better, but I'm not sure where to optimize. Based on what I've read, I think dropping in a OCZ Vertex 2 Pro SSD as my L2ARC is going to be the best bang-for-the-buck to improve througput. Is there something else I should be looking into to help performance? If not... How do I know how big a cache device I need? Am I safe with only a single SSD as my cache device?

• Has anyone used tools like (Chef, Salt, Puppet, CfEngine) to configure a 2008 Win Server with Sql?

  - by Development 4.0

  I have been looking into tools to automate the creation of servers. For two different reasons: Production Development machines I love the idea of the immutable server. I have seen the tools demoed and used successfully on *nix boxes running Rails or Lamp etc. Has anyone found a good way to do this in the Microsoft stack? I would like to get in on the fun and create scripts that will install Windows, patch it according to specification, deploy Sql Server create scripts to build out a database and just for fun deploy SharePoint and configure it, and then deploy a SharePoint solution to it. I can get part of the way, install Windows manually, install Sql Server manually, use Powershell to do all the configuration and setup. Install SharePoint and configure part of it, then powershell for the rest of the configuration and deploying a solution. I would love to have the ability to run one script though, or at least one unified process. I can, and have mostly used VM template images and then instantiated them, but the creation of the template is usually a manual step.

• Does Windows 7 Authenticate Cached Credentials on Startup

  - by Farray

  Problem I have a Windows domain user account that gets automatically locked-out semi-regularly. Troubleshooting Thus Far The only rule on the domain that should automatically lock an account is too many failed login attempts. I do not think anyone nefarious is trying to access my account. The problem started occurring after changing my password so I think it's a stored credential problem. Further to that, in the Event Viewer's System log I found Warnings from Security-Kerberos that says: The password stored in Credential Manager is invalid. This might be caused by the user changing the password from this computer or a different computer. To resolve this error, open Credential Manager in Control Panel, and reenter the password for the credential mydomain\myuser. I checked the Credential Manager and all it has are a few TERMSRV/servername credentials stored by Remote Desktop. I know which stored credential was incorrect, but it was stored for Remote Desktop access to a specific machine and was not being used (at least not by me) at the time of the warnings. The Security-Kerberos warning appears when the system was starting up (after a Windows Update reboot) and also appeared earlier this morning when nobody was logged into the machine. Clarification after SnOrfus answer: There was 1 set of invalid credentials that was stored for a terminal server. The rest of the credentials are known to be valid (used often & recently without issues). I logged on to the domain this morning without issue. I then ran windows update which rebooted the computer. After the restart, I couldn't log in (due to account being locked out). After unlocking & logging on to the domain, I checked Event Viewer which showed a problem with credentials after restarting. Since the only stored credentials (according to Credential Manager) are for terminal servers, why would there be a Credential problem on restart when remote desktop was not being used? Question Does anyone know if Windows 7 "randomly" checks the authentication of cached credentials?

• Mysql cluster strange behaviour

  - by Champion

  Hi Guys, I have 2 mysql clusters on two different servers with management node on each of them. It went down someway. I ran following commands to start the cluster: Start the management node on srv1: srv1: mysqlc/bin/ndb_mgmd --initial -f my_cluster/conf/config.ini --configdir=/home/mysql_cluster/my_cluster/conf Start the management node on srv2: srv2: mysqlc/bin/ndb_mgmd --initial -f my_cluster/conf/config.ini --configdir=/home/mysql_cluster/my_cluster/conf Start the ndbd nodes on srv1: srv1: mysqlc/bin/ndbd --initial -c localhost:1186 Start the ndbd nodes on srv2: srv2: mysqlc/bin/ndbd --initial -c localhost:1186 Start mysqld server on srv1: srv1: mysqlc/bin/mysqld --defaults-file=my_cluster/conf/my.cnf --user=root & and here is the problem. mysql server not loading the data. Only database names are present. All the tables which are ENGINE=ndbcluster are not being loaded. Tables with ENGINE=myisam are being loaded. Backup scripts helped me load the data. But this way I can't use cluster setup. Similar issue appeared when i started srv2. How can I resolve this issue ?

• Explorer.exe not starting after login on Windows Server 2003 (Terminal Services and console)

  - by Pepperoni Icecream

  When users login to a Windows Server 2003 R2 running Terminal Services they have a blank desktop. Upon inspection, explorer.exe is not running. When I login as administrator, using either RDP or to the console, I am having the same issue. I can pull up the taskman and start explorer.exe manually. I have another Terminal Server setup exactly the same way (same apps, settings, GPO, etc . . .) the only difference is we deployed Symantec Endpoint Client 11.0.5 on Friday. For some reason the working Terminal Server is still on 11.0.4, but the suspect server received the 11.0.5 client upgrade. I checked the eventviewer for any relevant explorer.exe entries to no avail. It seems that if SEP is preventing explorer.exe from starting at login it would do the same for the domain admin starting explorer.exe from the taskman. I disabled the SEP client and services on the server and issued smc -stop and tried logging in again. Still no explorer.exe. So I'm not sure if the client upgrade is relevant but it is worth mentioning since that was the last system change. The 2 servers are members of a NLB group. I took the bad terminal server out of the group until the issue is resolved. Actually stopped the host using NLB manager Any help is appreciated.

• CentOS security for lazy admins

  - by Robby75

  I'm running CentOS 5.5 (basic LAMP with Parallels Power Panel and Plesk) and have thus far neglected security (because it's not my full-time job, there is always something more important on my todo-list). My server does not contain any secret data and also no lives depend on it - Basically what I want is to make sure it does not become part of a botnet, that is "good enough" security in my case. Anyway, I don't want to become a full-time paranoid admin (like constantly watching and patching everything because of some obscure problem), I also don't care about most security problems like DOS attacks or problems that only exist when using some arcane settings. I'm in search of a "happy medium", for example a list of known important problems in the default installation of CentOS 5.5 and/or a list of security problems that have actually been exploited - not the typical endless list of buffer overflows that "maybe" a problem in some special case. The problem that I have with the usually recommended approaches (joining mailing lists, etc.) is that the really important problems (something where an exploit exists, that is exploitable in a common setup and where the attacker can do something really useful - i.e. not a DOS) are completely and utterly swamped by millions of tiny security alerts that surely are important for high-security servers, but not for me. Thanks for all suggestions!

• Postfix relay gives error 450 while it should be 550

  - by dieter-be

  Hi, we use postfix to do relaying. We get several messages like the following in /var/log/mail (slightly edited) Apr 13 13:30:29 linserver postfix/smtpd[1064]: NOQUEUE: reject: RCPT from unknown[$ip]: 450 4.1.1 <[email protected]>: Recipient address rejected: undeliverable address: host domain.be [$ip] said: 550 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table (in reply to RCPT TO command); from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<BLUESTREAK.domain.local> Now, when the master mail servers gives a 550, claiming that the user does not exist, I want the relay to also give a 550 back. What happens now is that it seems to return a 450, causing clients to keep messages queued, keep trying and only notify users after a certain period has passed. According to what I could find, the soft_bounce could cause this. But we have not enabled this option (and by default it's off according to postfix docs) It might also have something to do with the *_reject_code postconf values. Especially since the log message complains the unknown ip. But as you can see in the postconf output below, smtpd_sender_restrictions and smtpd_client_restrictions are empty. So even if it would try to do any restrictions there, 550 is the "worst" error going on, so that's what I expect to be returned to the client. postconf: http://sprunge.us/JYgB Thanks, Dieter

• Exchange Server 2010: move mailboxes from recoveded and mounted edb to user's mailbox

  - by user36090

  One of our exchange servers crashed, and I am trying to recover the mailboxes. We had 1 exchange 2003 server named "apex" and 1 exchange 2010 server named "2008Enterprise. the exchange 2010 server named "2008Enterprise" crashed. I created a new exchange 2010 server named "Providence". I ran the command on Providence: New-MailboxDatabase -Recovery -Name JBCMail -Server Providence -EdbFilePath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147\Mailbox Database 0579285147.edb" -LogFolderPath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147" this command executed and finished without error I then ran the command: eseutil /p E00 this command was executed from the below directory: c:\data\Exchange\Mailbox\Mailbox Database 0579285147 I then mounted the JBCMail with the mount command note: I do not have my full typed command. Inside my Exchange Management Console (EMC) I can view the new mailbox database named JBCMail. The JBCMail database is show as mounted on the exchange server named Providence. I can see the crashed Exchange server named 2008Exchange. In the EMC the crashed exchange server states the Copy Status under ServerConfiguration-Mailbox is ServiceDown. From here I need to recover three mailboxes The mail boxes are on the apex server. How do I move the mailboxs from apex to Providence? How do I restore the mailboxes from JBCmail mounted database to the user's mailbox? I do not fully understand how to use the Restore-Mailbox command because when I use this command it tries to restore the mailbox to the dead apex server.

• cfengine3 file_copy only on source side change

  - by megamic

  I am using the 'digest' copy method for all file copy promises, because of the way we package and deploy software, I cant rely on mtime for the criteria for updating files. For various reasons, I am not employing the client-server approach with a central configuration server: rather we package and deploy our entire configuration module to each server, so from cf-engine's perspective, the source and target are local on the server it is running. The problem I am having with this approach is that the source will always update the target when they differ - which is what I want most of the time, usually because the source has been updated. However, like many other cfengine users, we are running an operational environment, where occasionally emergency fixes have to be applied immediately - meaning we don't have time to rebuild and redeploy a configuration module, and the fix will often be applied by deploying a tarball with specific changes. Of course this is problematic if cf-engine comes along 5 mintues later and reverts the changes. What we would like is to be able to make small, incremental changes to our servers, without them being reverted, until the next deployment cycle at which time the new source files would be copied. We do not consider random file corruption or mistaken changes to involve enough risk to warrant having cfengine constantly revert deployments to their source copy - the ability to deploy emergency fixes and have them stay that way until the next deployment would be of much greater value and utility. So, after all that, my question is this: is cf-engine capable of detecting whether it was the source or target that changed when the files differ, and if so, is their a way to use the 'digest' copy method but only if the source side changed? I am very open to other ideas and approaches as-well, as I am still quite new to this whole configuration management thing.

• Linux Scheduler (not using all cores on multi-core machine) RHEL6

  - by User512

  I'm seeing strange behavior on one of my servers (running RHEL 6). There seems to be something wrong with the scheduler. Here's the test program I'm using: #include <stdio.h> #include <unistd.h> #include <stdlib.h> void RunClient(int i) { printf("Starting client %d\n", i); while (true) { } } int main(int argc, char** argv) { for (int i = 0; i < 4; ++i) { pid_t p_id = fork(); if (p_id == -1) { perror("fork"); } else if (p_id == 0) { RunClient(i); exit(0); } } return 0; } This machine has a lot more than 4 cores so we'd expect all processes to be running at 100%. When I check on top, the cpu usage varies. Sometimes it's split (100%, 33%, 33%, 33%), other times it's split (100%, 100%, 50%, 50%). When I try this test on another server of ours (running RHEL 5), there are no issues (it's 100%, 100%, 100%, 100%) as expected. What's causing this and how can I fix it? Thanks

• what web based tool, to allow a non-technical user to manage authorized keys files on a Linux (fedora/centos/ubuntu/debian) server

  - by Tom H

  (Edit: clarification below) We have a number of groups of developers that change frequently, and a security policy to require individual logins to servers using rsa or dsa public keys, which is achieved via the standard method of adding id_dsa.pub to their authorized keys file. I am using chef to sync the user accounts across machines, however our previous method of using webmin to manage the user passwords is not designed for key based auth, and hence is not easy to use for non-technical users. The developers are logging in from the WAN using ssh, they can either provide their own key, or an administrator will send them a private key. The development machines are located in the cloud and we have a single server available to host the master set of accounts. Obviously I could deploy ldap or other centralised authentication system, but that seems a bit over blown when webmin worked well for the simple case. It is easy to achieve synchronised users, groups and passwords across a bunch of low security development boxes using webmin clustered users and groups. However looking at the currently installed webmin it is not so easy to create the authorized keys as it is to create user accounts and passwords. (its possible, but its not easy - some functionality is in the usermin module, or would required some tedious steps) Ideally I'd like a web interface that is pretty much dedicated to creating users and groups, and can generate key pairs on the fly, and can accepted pasted in public keys to add to the users authorized keys file. If the tool sync'ed the users and keys as well, that would be great, but I can use chef to do that part if the accounts are created correctly on the "master" server.

• Move postfix maildir files from one mail server to another

  - by Tauren

  I have a new mail server configured as described in this howto: http://howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu-9.10 I also have an ancient mail server configured very similarly (using the same HOWTO, just for Fedora Core 6, if I recall correctly). Earlier today I had to switch from the old server to the new one, and the old one is no longer online. However, after I had migrated everything and switched it all over, I discovered a bunch of undelivered mail in the queue. It got delivered to the local mailboxes on the old server, so now there are a bunch of messages on it that I'd like to move to the new server. The new server has already received new messages, so I need to merge the files together somehow. For each user with an email of [email protected], there are files like this on both servers: /home/vmail/customer.com/username/maildirsize /home/vmail/customer.com/username/courierpop3dsizelist /home/vmail/customer.com/username/new/1271481177.Vca01I6006bM580357.mailhost.mydomain.com Can I simply copy the hundreds of files in the various new directories on the old server to the corresponding new directories on the new server? Will the maildirsize and courierpop3dsizelist files get updated automatically, or do I need to do something to update them?

• How to configure VirtualBox server for performance at home

  - by BluJai

  I currently have two physical Ubuntu Server 10.10 servers at home: one serves as our firewall/router/DHCP/VPN server and the other performs double-duty as a file server and a VirtualBox host for an Ubuntu Desktop 10.10 machine which I use from remote connections (via NoMachine) for many thin-client purposes which are irrelevant to my question. What I'd like to accomplish is to consolidate the two physical machines into one which is a dedicated VirtualBox host (most likely running Ubuntu Server 10.10). Note that I'd like to stick with VirtualBox (if possible) because I'm most comfortable with it and use it on a daily basis at both home and work. Specifically, I plan to have one VM set up as file server, another as the firewall/router/DHCP/VPN (or possibly split those a bit) and a third, which is the only current VM (already VirtualBox), which is the thin-client host. My question comes down to performance and/or recommendations about the file server VM. The file server hosts about 6 terabytes of data across 4 drives. What I'd like to do is use raw disk access from the VM directly to the existing disks. However, I'm curious what performance advantage/disadvantage that would have as compared to using shared folders from the VM host and basically just have the whole drive served as a shared folder to the VM which would then serve it to the other machines on the network. I don't know if virtual disks would even work in this scenario and I certainly wouldn't want a drive to be filled with just a single file which is 1.5 TB (disk image). To add understanding of context, but not to get additional advice, I want to virtualize these machines because I intend to regularly use the snapshot capabilities of VirtualBox for the system disks (which will be virtual drives) of the VMs and I have some physical space/power needs to address (as I mentioned, this is at home).

• What to do when launchpad is down?

  - by Jon

  As I am writing this (Friday, November 8, 2013 at 9:59:18 PM EST) launchpad is down. Apparently there is a power failure (https://twitter.com/launchpadstatus/status/398980619880775680). I tried running sudo apt-get update on my Ubuntu install. However, I simply get stuck on this: Ign http://ppa.launchpad.net precise InRelease 100% [Waiting for headers] Being a Ubuntu newbie, I tried to point my sources.list file to a different source. I backed up the original sources.list and then deleted the entire file to start afresh. I then added the following lines to it: deb http://mirror.anl.gov/pub/ubuntu/ precise main deb-src http://mirror.anl.gov/pub/ubuntu/ precise main I figured that since I have a different mirror, there would be no problem updating. I was wrong. I get stuck at the same place. I have several questions: Why do I need to hit launchpad? I do not reference it in my sources.list file at all. Is this something where the mirror redirects me to launchpad? Is there a good article out there that I can read on how exactly this whole apt-get update thing works that will help me understand why it is hitting launchpad? Is there any way to get my Ubuntu to update while launchpad is down? Isn't there any redundancy for the launchpad servers?

• Using "route add" to tell my computer to use a direct ethernet connexion instead of wifi ?

  - by TheSamFrom1984

  2 PCs are involved. Both are connected to the internet via Wifi on the same router. I can ping to/from each other and share folders flawlessly, but I'd like to be able to set a direct Ethernet link between them to speed up file transfers AND keep the Wifi connections (no gateway). So I plugged my RJ45 cable, and set up the connection. It works, but the PCs are only using this connection if one of them if disconnected from the Wifi. PC1 local address is 192.168.0.7 on its ethernet interface, and 192.168.1.21 on the wifi one. PC2 local address is 192.168.0.6 on its ethernet interface, and 192.168.1.22 on the wifi one. My question is : I'd like to using the route add command to tell PC1 to use the Ethernet interface when it needs to connect with PC2, by specifying "IF 2" at the end of the route add command. How can I do this ? I don't know what to put in the "gateway" parameter of the command, and everything I tried returns "the parameter is incorrect" (i don't know which one). ipconfig /all on PC1 : Windows IP Configuration Host Name . . . . . . . . . . . . : Sam-PC Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No Wireless LAN adapter Wireless Network Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : NETGEAR WG111v3 54Mbps Wireless USB 2.0 Adapter Physical Address. . . . . . . . . : 00-22-3F-DA-51-56 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::1d33:60b:476c:d396%12(Preferred) IPv4 Address. . . . . . . . . . . : 192.168.1.21(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : vendredi 27 novembre 2009 15:38:48 Lease Expires . . . . . . . . . . : dimanche 29 novembre 2009 07:33:04 Default Gateway . . . . . . . . . : 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 DHCPv6 IAID . . . . . . . . . . . : 301998655 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-12-7E-58-EA-00-1A-4D-59-B2-71 DNS Servers . . . . . . . . . . . : 192.168.1.1 NetBIOS over Tcpip. . . . . . . . : Enabled Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller Physical Address. . . . . . . . . : 00-1A-4D-59-B2-71 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::f598:c3a0:df8d:706e%11(Preferred) IPv4 Address. . . . . . . . . . . : 192.168.0.7(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : DHCPv6 IAID . . . . . . . . . . . : 234887757 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-12-7E-58-EA-00-1A-4D-59-B2-71 DNS Servers . . . . . . . . . . . : fec0:0:0:ffff::1%1 fec0:0:0:ffff::2%1 fec0:0:0:ffff::3%1 NetBIOS over Tcpip. . . . . . . . : Enabled

• Relax Linux - it's just me! (filesystem permissions)

  - by Xeoncross

  One of my favorite things about Linux is also the most annoying - file system permissions. In production machines and web servers I love how everything is so secure and locked down - but on development machines it really slows me down. I'll give one example out of the many that I discover weekly. Like most people, I dual-boot Ubuntu and Windows so I can continue using the Adobe CS4 suite. I often design web themes and other things while I'm still using windows. Later I'll boot into Ubuntu to take the themes and write the backend PHP for them. After mounting the windows C: drive partition I can copy the template files over so I can begin editing them. However, thanks to Linux desire to protect me I find that after coping the files I end up with a totally locked set of files where even I don't have read-write permissions. So after carful consideration about the tremendous risks that the HTML files pose to me - I chmod them so that I and apache can begin using them. Now given, the chmod process isn't that hard - but after you chmod enough files per day you get sick of doing it. I'm constantly creating, fetch, editing, and removing files from my user, git repos, php, or other random processes. This is a personal development machine after all. Everything changes on a day by day basis. So my question is, how can I get linux to relax about what I'm doing with my HTML/JS/PHP/TXT/SQL/etc. files so that I can work faster without constantly stopping to chmod things? I pinky-promise I won't hack into my account with an HTML file. ;)

• Windows Share authentication from Active Directory Linux login

  - by Kenny

  Hi, I'm using Active Directory to log into RHEL. To do this, I followed the steps outlined here: http://www.markwilson.co.uk/blog/2007/05/using-active-directory-to-authenticate-users-on-a-linux-computer.htm I'd like to be able to read data from Windows Servers shared folders without being prompted for a password. On Windows I log into an AD domain, and when I access windows file shares on a server on the LAN (also part of the AD domain) my I can just access them with no authentication step. I've used SMBclient on Linux to access these shares, but it asks for my password. I would like to be able to script access to the data on the shares, but I can't if there's a password prompt in the way. Well, I could, but it's not how I want to do it. Now, since I'm logged in using my active directory username & password, can't I just access the shares without jumping that extra hoop? I know I can mount the share using something like: //192.168.0.5/share /mnt/windows cifs auto,username=steve,password=secret,rw 0 0 but access will depend who is logged in... each user logging in should have their own unique AD access privelages. Thanks for reading!

• Is there a way to use something similar to a capture group for apache2 server name

  - by Zipper

  I have a server that sits behind an AWS load balancer. The LB can't do automatic redirect from HTTP to HTTPs, and the LB is doing my SSL. So I need to setup apache on my servers to redirect any request on port 80 to https://FOOBAR m where FOOBAR is the domain that came in. I haven't been able to find a way of doing that so far. I'm an apache newb though. What I'm trying to do is something similar to this. I'll use regex as an example <VirtualHost *:80> ServerName (.*) Redirect / https://\1 </VirtualHost> If there's a better way to do this, please let me know. EDIT: Sorry I should have explained why this is happening. I actually have a tomcat server running my app on port 8080, and the LB points to that. From what I can tell so far my requests come in on http (which is expected), but when my app server sends redirects (for login purposes) it tries to redirect to http, instead of https. I haven't had a chance to fully investigate this, but I wanted to work around it for now by point the LB to point to the apache server, and have any port 80 requests redirect to 443. EDIT2: The other reason I'm interested in doing this, is that since the LB can't do the redirect, I need to have another redirect mechanism in place to tell the browser to go to https://FOOBAR

• What are best practices on virtual lab/test bed architecture?

  - by WooYek

  I am currently preparing a new small virtual environment for development and testing with Windows Server + SQL Server + AD + Sharepoint + Exchange + IIS(ASP.NET) + Biztalk + ?, for a small (up to 5) dev team. What are pros and cons on different approaches, eg. splitting up over different machines or packing everything up per machine. I your experience what are the best practices I should follow in terms of architecture and various system/servers placement. What to share and what to split per person. I would like to achieve some flexibility for the dev and testing process (so teammebers would not be steeping on each other's toes) and limit administrative effort needed to propagate settings, integrate work items and revert changes when something breaks up. It's not supposed to be an everyday development working environment, more a tier 2 developer testing environment, and not yet an integration or QA testing environment with formal change process. IMO the two borderline solutions are: creating one all-inclusive machine for each dev team member giving them freedom to manage creating shared environment managed by the one with somehow formalized change request process What golden mean would you recommend, and why?

• Office 365 - Outlook shows Global Address List clicking "Rooms" during a meeting request

  - by TheCleaner

  This appears to be a "known" issue, but apparently no fix for it. However, I've been impressed before at the tenacity of the experts here to figure out an answer/fix. ISSUE When booking a New Meeting in Outlook (2013 or 2010) and choosing the Rooms button: The default list that opens is the Offline Global Address List: Which means a user has to change from the Offline Global Address List to the All Rooms list as shown here in order to easily pick from the list of actual rooms/resources: This isn't the default however for On-Premise Exchange servers. They default "correctly" to the All Rooms list when you click the Rooms button in the meeting request. While the option of using the Room Finder is there and does work, users have to know to click the Room Finder choice and it doesn't fix the actual root issue here. MY RESEARCH A few links I've found: http://community.office365.com/en-us/forums/158/t/41013.aspx http://community.office365.com/en-us/forums/148/p/24139/113954.aspx http://community.office365.com/en-us/forums/172/t/58824.aspx It was suggested that it might be that the "msExchResourceAddressLists attribute has incorrect value set". I checked my config by running: Get-OrganizationConfig | Select-Object ResourceAddressLists and the output was what it should be: ResourceAddressLists -------------------- {\All Rooms} QUESTION Does anyone have a fix that will make the All Rooms list be the default list when clicking the Rooms button in Outlook when using Office 365 / Exchange Online?

• sql 2008 disk layout on a budget this is for database mirroring

  - by user22215

  Guys I'm rolling out a SQL database server that will be used to back Sharepoint 2007. Right now I need some advice on my disk layout. I have two Dell servers that are configured a little differently in terms of storage. The principle server will be using a combination of local storage and san storage. I have to work with what I have the organization is currently all allocated on san storage it was like pulling teeth to even get what I have to work with now. My disk setup on the principle is as follows: raid 1 for OS raid 10 for logs raid 10 fiber on san for high IO databases raid 10 sata on san for content databases My question in regards to the principle server is where should I place the temp db? I thought about placing it on the fiber raid 10 which will be hosting my high IO Sharepoint SSP databases my only other choice is to move it to the raid 1 os partition which I’m sure you guys will be against. Now let’s talk about the mirror server it is not connected to the san it is all local 6 15k SAS drives. Now my question is the same do I put tempdb on the os partition or do I leave the os partition and use a single raid 10 for everything? Any help you can provide is much appreciated.

• Problems with X11GraphicsDevice on Suse 11

  - by Daniel

  Hi, On servers running Suse 11 I'm experiencing hangups in sun.awt.X11GraphicsDevice.getDoubleBufferVisuals(Native Method) when connecting via Citrix (and setting DISPLAY to localhost:11.0). Running exactly the same code in exactly the same environment, excepth through Exceed (with DISPLAY set to my workstation's IP) it runs like clockwork. The error is not intermittent, it happens every time Reinstalling the OS does not help Can not reproduce it on Suse 10 This is what the main thread stack looks like: [junit] "main" prio=10 tid=0x0000000040112000 nid=0x6acc runnable [0x00002b9f909ae000] [junit] java.lang.Thread.State: RUNNABLE [junit] at sun.awt.X11GraphicsDevice.getDoubleBufferVisuals(Native Method) [junit] at sun.awt.X11GraphicsDevice.makeDefaultConfiguration(X11GraphicsDevice.java:208) [junit] at sun.awt.X11GraphicsDevice.getDefaultConfiguration(X11GraphicsDevice.java:182) [junit] - locked <0x00002b9fed6b8e70 (a java.lang.Object) [junit] at sun.awt.X11.XToolkit.(XToolkit.java:92) [junit] at java.lang.Class.forName0(Native Method) [junit] at java.lang.Class.forName(Class.java:169) [junit] at java.awt.Toolkit$2.run(Toolkit.java:834) [junit] at java.security.AccessController.doPrivileged(Native Method) [junit] at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:826) [junit] - locked <0x00002b9f94b8ada0 (a java.lang.Class for java.awt.Toolkit) [junit] at java.awt.Toolkit.getEventQueue(Toolkit.java:1676) [junit] at java.awt.EventQueue.invokeLater(EventQueue.java:954) [junit] at javax.swing.SwingUtilities.invokeLater(SwingUtilities.java:1264) ... Has anyone experienced something similar? Could this be a problem in Suse 11's display handling? I'm thankful for any input at this point - I'm fresh out of ideas :)

• EEE PC dropbox server running 24/7

  - by microspino

  I'd like to create a mini dropbox and print server on a small soho network of 5 users (all of them use windows XP desktops). The device need to run 24/7 or at least 12/7 (I can accept just workday hours too but the other two options would be better). Dropbox mini server: I mean I will have a 90gb dropbox on every computer on my network LAN syncing with It and the one onto It syncing to the web. Print Server: I have Samsung SCX 4521F (fax/print/scan/copy), Samsung ML2010, HP Laser jet P1006, HP Color Laserjet CP1215, HP Office jet pro K8600, HP Design jet 500. All of them now are connected using little print servers and I want to get rid of them hooking everything to this mini server. The fax/print/scan/copy machine need to stay connected to a PC to make me able to use the software that comes with It. The mini server would save me on this too. Fax/Scan server: since I have the above mentioned fax/print/scan/copy machine I would like to make people use It from/to their computers through the mini server. I thought to a recent EEEBOX machine because I heard good things about ATOM cpus and because It seems that a recent BIOS version could switch It off and on autonomously. I'd like to listen some advice from You. Best of all would be: If You have something similar running for a long time If You disagree with this hardware choice and If You would suggest some other device. If You see any issues with my printing setup Anything else ;) My budget is from Zero (using right sw to build something on top on a old PC) to 500€ max.

• Changing Mac OS X 10.6 Routing after VPN'd In

  - by Matt Rogish

  I have a coffee shop around the corner that I use to do some work when I want to get away from home. They offer free wi-fi and I then use my Mac 10.6 VPN to log into my work network. I have "Send all traffic over VPN connection" checked. Before, their network was 10.0.0.x. I think they got a new router because it's now 192.168.2.x However, this interferes with one of the subnets at work so now I can't visit 192.168.2.x at work. So: 1) Office network: VPN gives IPs as 192.168.1.x. Another network is 192.168.2.x 2) Coffee network: Gives IPs as 192.168.2.x I think if I set a route to send all 2.x traffic over the tunnel, it would blow up my routing to their system, right? What should I do? I know the individual IPs of the servers I want... Maybe I could add each one, or can I add all of them minus the default gateway of their router? How do I set that up "temporarily" in my Mac? Thanks!!

• User cannot access a system DSN on Windows Server 2008

  - by Ra Osolage

  We run our SQL Server services using a low privileged domain account. That account is NOT a local admin on the OS. Only access I give the user account is assigned during install of SQL: full control over its mount points and then everything else is granted by the SQL Server 2005/2008 installer. I need to create a linked server in SQL Server 2008 to an ODBC data source. So I remoted into the computer using my domain account, which is part of a group that DOES have local admin privs to the OS. I created a system DSN and configured it to connect to another SQL Server. The DSN works perfectly when I test it. However, when I try to create the linked server, I get an error. It appears to me that the DSN is invisible to the domain account that SQL Server is running as. It seems that this problem is only happening to me on Windows 2008 servers. Does anybody know whether there's anything that you need to do after creating a DSN to make it visible for other users to access?
