• NAT confusion regarding cisco ASA5510

  - by LonelyLonelyNetworkN00b

  I'm setting up my first cisco firewalls. A little information first:I have two asa5510 setup in a working active/standby pair. From my ISP i have two public subnets. A /29 and a /26. On my DMZ interface i have the /26 configured. On my WAN Interface i have configured the /29 IPs. My isp routes the /26 via the /29 primary IP. I'm running ASA 8.2. I've turned NAT-Control off, because i don't want to use nat for for other than some internal interfaces. In essence i don't want to use NAT unless i specify it. I have a internal interface with the network of 192.168.100.0/24. I've tried setting up nat limke this: nat (inside) 1 192.168.100.0 255.255.255.0 global (WAN) 1 interface I was under the impression that this would let connections that was going from 192.168.100.0/24 and out the WAN interface to be Port-Address-translated. I'm not getting this to work for some reason. Inside interface has security level of 100, and wan has security level of 0.

• Active Directory + IIS + SQL + ASP.NET

  - by Amira Elsayed Ismail

  I have sent the following question to stackoverflow website I have installed Windows server 2008 r2 on a virtual machine, Can I install Active directory with domain controller + IIS + SQL server on the same machine? I want to make web application and this web application will authenticate users from Active Directory, the web application should be published on the server IIS and the users should access it remotely from their home using domain name of my machine, Someone tell me that its very wrong to have IIS and Active directory on the same machine I got the following Answer You can't use ActiveDirectory over the internet. At least not without something like a VPN as a middle man. Their home computers will not be joined to the domain, so there is no pass-through authentication. Yes, it's a bad idea to put AD on the web server. Why is too complex to get into in an answer here. Suffice it to say that even if you did do this, it's probably would not work the way you are thinking it should. It's not impossible to do this. For instance, many of the Microsoft "Small Businesss" products put IIS, AD, and SQL Server on the same server. But, you kind of have to know what you're doing to configure it securely. Then I add the following comment Thanks for ur reply.so what you think about the best way to do this as I didn't do anything like that before should I install active directory on a machine and IIS on another machine ? and what about SQL should I add it to the same server of active directory ? I didn't mentioned also that it will be Microsoft dynamics server that will access some information about work and i have to read data from axapta also ? also what is VPN and how can I use it to let users access my web application anywhere ? Sorry for my long questions and thanks in advance so please if anyone can help I will be thankful

• Typing Japanese on Windows Vista with Dvorak

  - by Ken

  I'm using Windows Vista, and I type English with the Dvorak keyboard layout, and I want to be able to type Japanese text that way, too. I've figured out how to set it up to let me type Japanese here, but it uses QWERTY. What I've got so far is: click the "EN" in the taskbar, and select "JP" if the letter that appears in the taskbar is "A", hit alt-~ to change it to "?" type as if I was typing Romaji on a QWERTY keyboard, (e.g., left pinky home row, right ring finger top row), and hiragana appear (??) press spacebar to convert to kanji (e.g., ?), and return to accept That all works great, but it assumes I'm on QWERTY, which isn't very comfortable for me. I want everything the same, but to be able to type kana with Dvorak (e.g., left pinky home row, left ring finger home row - ??). I can do this on Mac OS, so it's not an unheard-of feature. But it was kind of an obscure setting to find, so I figure on Windows it's probably a really obscure setting. :-) But I haven't been able to find it yet. Thanks!

• How to remove Character Style in Word 2003

  - by joe

  I am copying text into a Word document that has its styles protected. Some of the text has a Character style applied to it that I would like to remove. I can change the style and it looks okay visually, but when you click inside the text itself you can see in the style menu that the Character style is still applied. I try to change the style using the style drop down but the Character style won't go away even if I change it to the Paragraph style. Does anyone know what I am talking about and/or have any techniques for removing Character styles? I am looking forward to your responses. Let me know if I need to clarify. Thanks! UPDATE: My issue is that the Paragraph style is changing correctly, but the Character style remains applied even though the text is displayed as if the style is not applied. See http://office.microsoft.com/en-us/word/HA011876141033.aspx if you are not sure what I meen by Character styles. There are four types of styles — paragraph, character, list, and table (list and table styles are new as of Word 2002). However, the majority of styles you'll use are paragraph styles.

• How would I force Debian to use the physical sector size on a hard disk?

  - by Confused User

  I just purchased a few new 3TB WD drives. These have physical 4k sectors, but there is some sort of layer which is providing 512B logical sectors (see the partition table below). In order to attempt to get some more speed out of my hard drives, I would like to get rid of this logical layer and actually use the physical 4k sectors. However, I can't figure out how to do this (or even if it's possible) from the man pages of fdisk and parted, or from searching Google. Does anybody know how this could be done? As to why this is relevant, this page demonstrates that meerly aligning the sectors properly can already make up to a 25% speed difference for reads, and more than 2500% for writes in some cases! Getting rid of the logical sectors in favor of the physicals ones should improve speeds even more. Thanks! $ parted /dev/sdc GNU Parted 2.3 Using /dev/sdc Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Model: ATA WDC WD30EZRX-00M (scsi) Disk /dev/sdc: 3001GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 3001GB 3001GB zfs 9 3001GB 3001GB 8389kB P.S. I don't care about the data on the drives, I was just playing with different file systems. Also, this is my first time posting here, so please let me know if my posts should be formatted differently, etc.

• Bluescreen Stop 0x00000027 RDR_FILE_SYSTEM after cloning system on new HDD

  - by Daniel

  A couple of months ago I got a new 500GB HDD for my no-name-brand Laptop PC and I cloned the complete Win 7 Pro 32bit system with clonezilla from the old 70GB drive to the new one. At first everything was great, the new driver was immediately updated. But since then I get on a more and more frequent level (used to be every 2-3 days, but now it's more like 2-3 times a day) a BSOD Stop error. From the eventlog in Windows I know that there are two different error codes sppoking aroung: 0x00000027 (0xbaad0073, 0x9954f80c, 0x9954f3f0, 0x8ecd7c82) RDR_FILE_SYSTEM 0x00000044 (0x85443230, 0x00000eae, 0x00000000, 0x00000000) MULTIPLE_IRP_COMPLETE_REQUESTS I checked for viruses and did a complete HDD check using the Windows tool and WesternDigital tool (which is the producer of the new HDD) without results. I also looked for driver updates but couldn't find any. The name of the HDD as shown in the device manager is: WDC WD5000BPVT-00HXZT1 ATA Device. I'm really a noob regarding those kind of problems, so if you have any idea what I can try without losing all my data, let me know. Also, if any additional information are required.

• 403 with Apache and Symfony on Ubuntu 10.04

  - by Dominic Santos

  I'm trying to run symfony on my apache installation (I'm using xampp for the whole package) and it keeps giving me a 403 error every time I try to access my website. I've got vhosts set up with the following: <VirtualHost *:80> ServerName localhost DocumentRoot "/opt/lampp/htdocs" DirectoryIndex index.php <Directory "/opt/lampp/htdocs"> AllowOverride All Allow from All </Directory> </VirtualHost> <VirtualHost *:80> ServerName servername.localhost DocumentRoot /home/me/web/server/web DirectoryIndex index.php Alias /sf "/lib/vendor/symfony/data/bin/web/sf" <Directory "/home/me/web/server/web"> AllowOverride All Allow from All </Directory> </VirtualHost> <Directory "/lib/vendor/symfony/data/bin/web/sf"> Allow from All </Directory> I've also added "127.0.0.1 servername.localhost" in my hosts file. When I try to access "servername.localhost" it just gives me a 403 error. I've chmod'd 777 the symfony directory and my website directory in my home directory and used './symfony project:permissions' to let symfony check that permissions are set up correctly but still not result. If I move my website directory into "/opt/lampp/htdocs" then it will serve it from there but still has problems access the symfony stuff such as the debug toolbar. Any help would be appreciated.

• Desktop bigger than screen

  - by alex

  I am using MSI U115 11" netbook (OS: Windows XP Home, graphics card: Intel Graphics Media Accelerator 500) and today after I switched it on, desktop was bigger than screen. To be exact: screen resolution was set to the lowest possible and I could move mouse outside of screen (but only below - left, right and up worked normally, mouse could not exceed screen boundaries). I changed resolution back to normal, but the problem with desktop being bigger than screen remained (as before, only lower part - cannot see task bar, etc. When I hit windows button on keyboard, only upper part of menu start is visible). What I already tried was changing all kind of graphics and screen settings - none of them helped. I also tried to restore the system to few days before, but it didn't help neither. What can I do to make the desktop look "normally"? EDIT: Some additional info regarding screen: Sorry it's in polish - but let me explain. There are two screens I can choose (Monitor domyslny means default screen), but the second one (the default one) is not available. After I choose it and click apply number 1. is used (and as you can see it has only two resolutions available. There are more in the second one - but without 1024x600 though). The two ticked and grayed out options here are Use this screen as the main one and Enlarge Windows desktop to match this monitor's size. Too bad I cannot change them. When I choose the second screen, the first box is unchecked and grayed out. The second box is available to be changed but it doesn't matter anyway as after applying changes it reverts to the first screen anyway. EDIT: Intel Graphics Media Control Panel screenshot.

• Anonymous access to SMB share hosted on Server 2008 R2 Enterprise

  - by bwerks

  Hi all, First off, I have read through this post and a whole slew of non-SF posts which seem to address the same or a similar problem, however I was still unable to fix my problem. I've got three machines in this situation: a domain-joined server that runs Server 2008 R2 Enterprise ("share server") a domain-joined workstation running XP Pro SP3 ("test server") a domain-unjoined test server running Server 2003 R2 SP2 ("workstation") The share server is exposing a share on the network that the test server must access--it's a Source/Symbol Server share for our debugging purposes. I believe visual studio simply accesses the the share with its own credentials in this case, meaning that the share must be accessible anonymously since the test server isn't joined to the domain and there's no opportunity to supply domain authentication. I've attempted a lot of things to avoid the authentication window when accessing the share: I've enabled the Guest account on the share server and given Guest full sharing/NTFS permissions for the share. I've given ANONYMOUS LOGON full sharing/NTFS permissions for the share. I've added my share to “Network Access: Shares that can be accessed anonymously” in LSP. I've disabled “Network access: Restrict anonymous access to Named Pipes and Shares” in LSP. I've enabled “Network access: Let Everyone permissions apply to anonymous users” in LSP. Added ANONYMOUS LOGON to “Access this computer from the network” in LSP. Added the Guest account to “Access this computer from the network” in LSP. Attempted to provision the share using the Share and Storage Management MMC snap-in. Unfortunately when I attempt to access the share from the test server, I still see the prompt and I'm forced to enter "Guest" manually. I also tried this workflow using the local administrator account on a workstation, and the same thing happens both with and without XP Simple File Sharing enabled. Any idea why I'm getting these results, or what I should have done differently?

• How would I setup iMail to forward a user's mail to another service w/o leaving a copy locally?

  - by Scott Mayfield

  I have an iMail 2006 server installation in which I have a particular user that has several aliases that all point to a single user (me, for the record). I've been copying all of my mail to GMail and reading it there, but it annoys me that I have to go back weekly and log into my mail account on iMail and delete between 6 and 10 thousand copies of messages I've already received, in order to keep my mailbox from filling up (yes, I have it set with no quota, but I consider it bad form to just let the box grow indefinitely). I've got the copying setup via an inbound user rule, but I'm wondering how to accomplish a "copy and delete" rule. The manual isn't clear on what happens with multiple matching rules (will they be processed in order, or is it a first match situation?) and there isn't a means to combine multiple actions into a single rule. If I use the "forward" action, I THINK that it's going to screw up all the sender information once the mail reaches my GMail account and show it as coming from me instead of the original senders (can anyone confirm that this is accurate?) An easy answer would be to delete my user account entirely, replace it with an alias that maps to my GMail account, but then I would lose my ability to log into the system for admin duties. So that leads me to creating a second, lesser known account for admin use, but since it's a real account, sooner or later I'm going to get mail sent to it and I'll be back to the same situation of having a user account that doesn't get emptied periodically. I imagine I can set the quota to 0 MB to cause all incoming mail to my admin account to bounce, or setup an inbound rule to bounce everything, but this is starting to sound kludgy to me. Does anyone know of a more direct work around to copying a user's incoming mail to an outside server and then deleting the local copy w/o removing their account entirely? Or is this just wishful thinking?

• How can I systematically shut down Windows services in order?

  - by cbmeeks

  We have this open source application that has three (3) services. For the purpose of this question, let's call them A, B, and C. Now, they have to be shut down in a specific order. That order would be A then B then C. If B shuts down before A then we run into all kinds of problems. Same is true if C shuts down before B or A. Plus, each service can take a different amount of time to shut down due to how many users were using it. Oh, this need to be wrapped up in a DOS batch file or something a non-techy user could just double-click to initiate. (PowerShell is not out of the question but I've never used it). Also, I'm a C# coder so that could be used too. Anyway, when the restart is initiated the following needs to happen: 1) Initiate shutdown of service A 2) When service A is down, it should trigger the shutdown of service B 3) When service B is down, it should trigger the shutdown of service C 4) When service C is down, it should trigger the START UP of service A 5) When service A is UP, it should trigger the START UP of service B 6) When service B is UP, it should trigger the START UP of service C So as you can see, each stop/start needs to wait on the previous to be completely finished before moving on. And since each service can take a few seconds to a few minutes, we can't use any kind of timing tricks. Suggestions greatly appreciated. Thanks!

• Excel 2007 pivot table does not aggregate properly

  - by Patrick

  I am using a an excel pivot table to summarize some data and just found a problem. The problem deals with how aggregate values are calculated. Let's say I have a table of data with three columns: Name, Date, Value. If I create a table where Name and then Date are used as Row Labels and Value is the aggregate value, ie Average. The pivot table will look something like this: +John .3450 5/14/2010 1.234 5/15/2010 3.450 5/16/2010 -3.25 What I think should be happening here is that the values for each date are averaged and then those values are averaged to come up with the value in the same row as the Name, John. But that is not what it does. It takes the average for each date, which it shows across from the date, but then instead of taking the average of those numbers, it actually uses the raw data and computes the average for all of John's values. It should show the average of the daily averages to correspond with the tree hierarchy, but instead just shows me the average for all of John's values. It essential will only aggregate at one level, but visually creates sub levels that it is not using. Does anyone know how to change this or understand by what logic this makes sense? Why would I create any sub groupings if I cannot compute aggregates on them?

• Permission problem with Git (over SSH) on FreeBSD

  - by vpetersson

  We're having permission problem with Git on FreeBSD. The setup is fairly straight forward. We have a few different repos on the same server. For simplicity, let's say they reside in /git/repo1 and /git/repo2. Each repo is owned by the user 'git' and a self-titled group (eg. repo1). The repo is configured with g+rwX access. Every user who commits to the repository is also member of the group for the repo (eg. repo1). The Git repositories all have 'sharedRepository = group' set. So far so good, all users can check out the code from the repositories, and the first user can commit without any problem. However, when the next user tries to commit to the repositories, he will receive a permission error. We've been banging our heads with this issue for some time now, and the only way we've managed to resolve it is by running the following script between commits (which is obviously very inconvenient): find /git/repo1 -type d -exec chmod g+s {} \; chmod -R g+rwX /git/repo1 chown -R git:repo1 /git/repo1/ cd /git/repo1 git gc Anyone got a clue to where the problem lies?

• How to move Mdadm RAID drive (EBS based) to different AWS Instance

  - by Stanley

  We have a media-rich web application that is hosted on AWS. We have several Web Servers and we have an NFS server. On the NFS server (Linux server) we have several EBS volumes that are mounted and we've used mdadm to implement the different mounted volumes as a single RAID volume. The Web Servers simply access the NFS storage through a mount point. Amazon has now let us know that they will be performing power maintenance on this server in a couple of days time. Since all our media is on here it would render our site unusable for the hours while Amazon is working on it. We want to try and prevent this downtime. I was thinking that we can prevent server downtime by perhaps setting up a new server temporarily and attaching the EBS drives (raid volume) to that server and have our web servers point there during maintenance. This is a very high risk operation since this involves several terabytes of our production data. What would be the safe way to move over our logical raid drive (md0) to a new amazon instance? I was hoping that I could start with building the new server, mounting the ebs volumes and assembling the RAID partition using mdadm --assemble --scan before unmounting from the existing instance so that I can first test that everything works and thus having it mounted on two instances at the same time, but I don't believe that is possible with the way that filesystems work. How do I move a Linux software RAID to a new machine? suggests a way to move drives, but isn't really a cloud-based question. Perhaps there are simpler ways to prevent system downtime with our solution being hosted on the cloud? I have considered taking an EBS snapshot, but that tries to replicate all the many terabytes of mounted storage, so this is not a practical solution. Any ideas?

• Haproxy and CNAME

  - by user123354

  I want to create a simple load balancer for the two servers. The problem is with CNAME records, I think. Let's say I have two the same applications on AppFog.com. app1.aws.af.cm and app2.aws.af.cm Here is my haproxy.cfg file: global maxconn 2000 daemon defaults mode http clitimeout 60000 srvtimeout 30000 contimeout 4000 option httpclose listen http_proxy bind [myip]:80 mode http stats enable stats auth user:passwd stats uri /stats balance source option httpchk option forwardfor server host01 app1.aws.af.cm:80 maxconn 300 check server host02 app2.aws.af.cm:80 maxconn 300 check But this only resolving IP for domain app1.aws.af.cm and app2.aws.af.cm, which obviously doesn't work if I open this IP in web browser. The problem is that AppFog doesn't have public IP for application (same as OpenShift). How to do that Haproxy to perform a proper connection between Load Balancer and this two servers? Example: This is real app - http://freechat.eu01.aws.af.cm Haproxy only resolves IP for this domain which is 46.51.204.8:80 Of course this IP will not show my application, only an error page. Sorry for my poor English.

• Router startup problems

  - by gfmoz

  I have problems with my Tilgin Vood Router. As I try to start my router by turning the power on (captain obvious), it generally doesn't work the first 3-4 times. This is getting very annoying. Five minutes after turning the power on the router's signal LEDs don't blink in the way they should do in a connected state. I can connect to my routers web configuration interface through my PC connected to it via LAN though I can't access the internet. It usually takes the router five minutes to get to the point where it should be connected to the internet but as it doesn't work the first times. So I turn on my router 3-5 times, let him work 5 minutes and then suddenly, after turning the power off and on again it all works. I also have to restart my PC too in order for everything to work. How can I solve this problem? Just leave the router turned on all time? I prefer a daily IP switch, though. May the problem have something to do with my PC? There is another one connected to the router too and it doesn't work there either.

• Constant beeping

  - by Bogi Juul Peterson

  My computer has a problem with beeping. I'll first tell you how it started: One night I decided to watch a cartoon, and I took some water and food with me to eat while I watch. I fell asleep and when I woke up I had spilled water all over my keyboard. I didn't react quickly, because it went unnoticed for about 1 and a half hours. When I noticed, I quickly put my laptop on a radiator to try to dry it. When I turned the computer on there was a constant beeping sound. I didn't know what caused it, and I'm still not sure, but I think it has something to do with the USB hub. If I let the computer stand for some hours without any USB connections, it's fine, but when I put any kind of USB device in, it starts beeping. The laptop keyboard doesn't work so I have to have some kind of USB device connected to use the computer. The beeping is going on while I'm writing this and it makes my computer lag so much that it can make delays from the keyboard be from 1 second to 10 seconds. I need this computer because I don't have the money to buy a new one, and I have to use this computer for homework and games. The beeping is constant, with less than a second between beeps. If anyone has a solution, please help.

• IP-dependent local port-forwarding on Linux

  - by chronos

  I have configured my server's sshd to listen on a non-standard port 42. However, at work I am behind a firewall/proxy, which only allow outgoing connections to ports 21, 22, 80 and 443. Consequently, I cannot ssh to my server from work, which is bad. I do not want to return sshd to port 22. The idea is this: on my server, locally forward port 22 to port 42 if source IP is matching the external IP of my work's network. For clarity, let us assume that my server's IP is 169.1.1.1 (on eth1), and my work external IP is 169.250.250.250. For all IPs different from 169.250.250.250, my server should respond with an expected 'connection refused', as it does for a non-listening port. I'm very new to iptables. I have briefly looked through the long iptables manual and these related / relevant questions: http://serverfault.com/questions/57872/iptables-question-forwarding-port-x-to-an-ssh-port-of-different-machine-on-the-n http://serverfault.com/questions/140622/how-can-i-port-forward-with-iptables However, those questions deal with more complicated several-host scenarios, and it is not clear to me which tables and chains I should use for local port-forwarding, and if I should have 2 rules (for "question" and "answer" packets), or only 1 rule for "question" packets. So far I have only enabled forwarding via sysctl. I will start testing solutions tomorrow, and will appreciate pointers or maybe case-specific examples for implementing my simple scenario. Is the draft solution below correct? iptables -A INPUT [-m state] [-i eth1] --source 169.250.250.250 -p tcp --destination 169.1.1.1:42 --dport 22 --state NEW,ESTABLISHED,RELATED -j ACCEPT Should I use the mangle table instead of filter? And/or FORWARD chain instead of INPUT?

• Weird caching bug where old version of the same web page (same filename) is still called (Windows 2008 R2, Tomcat 5.5)

  - by user717236

  This is definitely one of the strangest errors I've seen and it occurs intermittently. I am running Windows 2008 R2, IIS 7.5, and Apache Tomcat 5.5, by the way. Let's say I have two machines, A and B. Both A and B are running Windows 2008 R2. I have a web page called login.jsp on machine A, and I have a newer, modified version of login.jsp on machine B . Now, I copy the new login.jsp from machine B and paste it to machine A, replacing the older version with the same filename. For whatever reason, when I hit up the web page in my browser from a local machine (i.e. my laptop), it still recalls the old version of the web page, even though it's been replaced! I tried restarting IIS and Apache Tomcat. That didn't work. I tried restarting machine A and that didn't work. I tried a cold reboot of my local machine and that didn't work, either. So, I spoke to someone I can confide in for help. He said to open the login.jsp page in notepad, put a space in, save the file, and try again. Sure enough, it worked. He said he hasn't seen it in Windows 2003, but this is occurring with Windows 2008. What I don't understand is why did it work and what the heck is this error and I do I really diagnose it and resolve it for good, instead of the hack my colleague proposed? Is this bug related to Windows 2008, Windows 2008 R2, Tomcat, or something else entirely? Anyone else have the same problem? Thank you for any help.

• What is the best way to connect a 3 switches with a router?

  - by Carlos Morales

  Hello everyone, I'm trying to rebuild the network from my work and I was thinking what is the best way to connect three switches and a router. The router has 4 ports so I thought to connect 2 switches to the router (each switch connected with 2 cables to the router) and then connect the third switch to one of the others with two cables. So is like this, two cables from switch one to the router, two cables from switch two to the router and two cables from switch 3 to switch 1 or 2. So my questions are: Is it better to connect the router to each switch with a cable or the more cables you have the better? If I connect the switch 3 to switch 1 or 2 is it better to connect it with a cable or you get better performance with more cables. If I'm wrong and there is a better or more efficient way to connect them please let me know. The router is a Netgear RP114 (I'll upgrade it to a Sonicwall NSA 240), switch 1 is a Netgear GS748T, switch 2 is a Cisco Catalyst 2924-XL and switch 3 is a D-link DGS-1024D Thank you very much

• DAS vs SAN storage for serving 2 to 4 nodes

  - by Luke404

  We currently have 4 Linux nodes with local storage, arranged in two active/passive pairs with storage mirrored using DRBD, running virtual machines (actually using Xen Hypervisor) for typical hosting workloads (mail, web, a couple VPS, etc.). We're approaching the (presumed) maximum IOPS of those servers, and we're planning to migrate to an external storage solution with two active nodes, with capacity for up to four active nodes. Since we're an all-Dell shop I've done some research and found the MD3200 / MD3200i products should be the ones we're looking for. We are pretty sure we won't be attaching more than 4 hosts on a single storage and I'm wondering if there is any clear advantage for one or the other. In theory I should be able to attach 4 SAS hosts to a single MD3200 (single links on a single controller MD3200, or dual redundant SAS links from each host to a dual-controller MD3200), or 4 iSCSI hosts to a single MD3200i (directly on its 4 GigE ports without any switch, again with dual links for the dual controller option). Both setups should let us implement live VM migration since all hosts can access all the LUNs at the same time, and also some shared filesystem like GFS2 or OCFS2. Also, both setups should allow full redundancy of the whole system (assuming dual controllers in the storage). One difference I can see is that the DAS solution is actually limited to 4 hosts while the iSCSI one should be able to grow to more hosts (adding two GigE switches to the mix). One point for the iSCSI solution is that it would allow us to start out with our current nodes and upgrade them at a later time (we can't add other SAS controllers, but they already have 4 GigE ports each). With the right (iSCSI|SAS) controllers I should be able to connect diskless nodes and boot them off the external storage which I think is a good thing (get rid of any local storage). On the other hand, I would have thought the SAS one to be cheaper but it seems like an MD3200 actually costs a little less than an MD3200i (?) (please note: I've used Dell gear in my examples since that's what we're looking for but I assume the same goes with other vendors) I would like to know if my assumptions above are correct, and if I'm missing any important difference between the two setups.

• Can't Connect w/ SQL Management Studio After Domain Change

  - by Sam

  Our old Small Business Server 2003 (acting as our domain controller) was on the fritz, so we replaced it with a new Windows Server 2008 box and set the server up as our new domain controller. In hindsight, it may have been a mistake, but we set up the new server as a replacement and tried to keep as much the same as possible, including the DOMAIN name. The problem was, that even though the domain name was the same, the guest computers somehow still realized it was not the exact same domain. We had to unjoin and rejoin the domain and port over everyone's documents and settings. This morning, when I attempted to connect to my local SQL Server Instance, it was saying that my login failed. When I tried to use the SQL Management Studio, it throws the error "Package 'Microsoft SQL Management Studio Package' failed to load" on startup, then exits without giving me a chance to change the login. I am using Mixed Authentication and have an administrative account as a backup. Ideas? If there is a more appropriate stack, please let me know where to put it.

• Proper way to use hiera with puppetlabs-spec-helper?

  - by Lee Lowder

  I am trying to write some rspec tests for my modules. Most of them now use hiera. I have a .fixures.yml: fixtures: repositories: stdlib: https://github.com/puppetlabs/puppetlabs-stdlib.git hiera-puppet: https://github.com/puppetlabs/hiera-puppet.git symlinks: mongodb: "#{source_dir}" and a spec/classes/mongodb_spec.rb: require 'spec_helper' describe 'mongodb', :type => 'class' do context "On an Ubuntu install, admin and single user" do let :facts do { :osfamily => 'Debian', :operatingsystem => 'Ubuntu', :operatingsystemrelease => '12.04' } end it { should contain_user('XXXX').with( { 'uid' => '***' } ) should contain_group('XXXX').with( { 'gid' => '***' } ) should contain_package('mongodb').with( { 'name' => 'mongodb' } ) should contain_service('mongodb').with( { 'name' => 'mongodb' } ) } end end but when I run the spec test, I get: # rake spec /usr/bin/ruby1.8 -S rspec spec/classes/mongodb_spec.rb --color F Failures: 1) mongodb On an Ubuntu install, admin and single user Failure/Error: should contain_user('XXXX').with( { 'uid' => '***' } ) LoadError: no such file to load -- hiera_puppet # ./spec/fixtures/modules/hiera-puppet/lib/puppet/parser/functions/hiera.rb:3:in `function_hiera' # ./spec/classes/mongodb_spec.rb:15 Finished in 0.05415 seconds 1 example, 1 failure Failed examples: rspec ./spec/classes/mongodb_spec.rb:14 # mongodb On an Ubuntu install, admin and single user rake aborted! /usr/bin/ruby1.8 -S rspec spec/classes/mongodb_spec.rb --color failed Tasks: TOP => spec_standalone (See full trace by running task with --trace) Module spec testing is relatively new, as is hiera. So far I have been unable to find any suitable solutions. (the back and forth on puppet-dev was interesting, but not helpful). What changes do I need to make to get this to work? Installing puppet from a gem and hacking on rubylib isn't a viable solution due to corporate policy. I am using Ubuntu 12.04 LTS + Puppet 2.7.17 + hiera 0.3.0.
