• Mac Joining Active Directory Still Prompts For Authentication

  - by David Potter

  My Mac is joined to an Active Directory domain. What I expected to see was the same ease of access to file shares and internal websites that Windows computers joined to the domain experience (i.e., no authentication needed; it just uses Windows Integrated Authentication). Instead I am asked for credentials each time I try to access those shares and protected websites (e.g. SharePoint). Is this normal behavior, or is something wrong with my Mac that it prompts me for my username and password for the domain when I access Windows file shares or intranet sites protected by NTLM/Kerberos? Machines include: MacBook Pros running Mountain Lion MacBook Pros running Lion MacServer running Lion Server

• Port binding conflicts with "switch user" on Windows 7

  - by C-dizzle

  We are using the switch user function within Windows 7 under an active directory network. We have one application in particular that gives us an error: Only one usage of each socket address (protocol/network address/port) is normally permitted. bind Port 10001 Are there any other ports that can only be used at one time that might have an adverse effect on the other user? We try to mentor our users to use the log off function instead of switch user, but that doesn't always happen. As an alternative, is it possible to disable the 'switch user' button on our machines?

• Disk Redundancy across different server

  - by Mascarpone

  I have 3 servers, all with the same specs: Intel CPU 8 GB RAM Linux or BSD Single 2TB desktop SATA with more than 10K Hours of operation, with only less than 300 GB Used My provider cannot install a second hard drive, but can guarantee me that the drive will be replaced immediately in case of failure, with another equally crappy drive. The likelihood of drive failure is high, and since I can't use RAID, I was thinking about keeping a back up of each machine on all the other machines, so that there are always 2 copies on 2 different drives, plus the original. I would synchronize the drives every hour, with rsync, to guarantee some sort of redundancy, since bandwidth inside the DC is free, so it would be much cheaper than offsite backup. (A daily offiste backup is kept anyhow). What do you think? Any suggestion?

• How do I access a shared folder using credentials other than the ones I logged in with?

  - by George Sealy

  I have a lab full of Windows 7 machines, and a shared login (user360) that all my students use. I also have a shared folder that they can all have read/write access to (for moving files around easily). My problem is that I also want to be able to create a shared folder for each student for submitting assignments. I can set up a shared folder with permissions for just a single user, and not the 'user360' account. The problem is, when I'm logged in as user360, and I try to open the 'StudentA', Windows never asks me for alternate credentials, it just refuses access because the user360 account is not allowed access. Can anyone suggest a fix for this?

• Where in the user profile are the Firefox search engine choices stored?

  - by N Rahl

  We have a large number of user profiles that were created on Ubuntu 10.04 and they had access to Google as a choice in the search bar and Google was the provider for queries typed into the super bar. When logging into these same profiles from Mint 15 client machines, the Google search option does not exist for these users, as is the default for Mint. This setting seems to be user specific, but not a part of the FireFox profile? It seems if it were a part of the FF profile, it would "just work" on Mint for these profiles, so I suspect the configuration may be stored somewhere else in the user's profile? Could someone please tell me where in a user's profile the search engine options are set? We would like to set this once, and then drop this configuration into everyones profile so all of our users don't have to do this manually.

• Open source alternative for Canonical Landscape?

  - by netvope

  From Canonical: Landscape is an easy-to-use systems management and monitoring service that enables you to manage multiple Ubuntu machines as easily as one through a simple Web-based interface. However, Landscape is not free. The RedHat counterpart Satellite has a free version called Spacewalk, but it doesn't work on Ubuntu. (There is an attempt to port Spacewalk to Debian, but it doesn't look like it's stable yet.) Are there any open source alternative to Landscape? Better yet, are there any Spacewalk-like software that works for both RedHat-based and Debian-based systems?

• PPTPD with PAM authentication?

  - by Richard

  I need a VPN solution for my company. One requirement is to be able to use the built-in windows VPN client. We are running a Debian Etch server. I've managed to set up PPTPD but the authentication is based on the chap-secrets file. We already have all the user accounts set up on the server, so it'd be nice to use PAM authentication to get user/pass directly from the unix login. Is this possible to achieve and how? If not, is there any other VPN solution that can do this? Don't tell me OpenVPN, it needs additional software to be installed on the Windows machines. :)

• IIS 7 URL rewrite rule

  - by Andrew

  Hello, guys! We have here to web servers behind a router - one IIS and one Tomcat (on different machines / IP addresses). The domain is pointing to out external IP, which is forwarded to IIS (internal IP 192.168.1.10 for example). I'm trying to do the following: when [www.]ourdomain.com is entered the default web site on IIS have to be loaded (this part is ok), but when test.ourdomain.com is entered I want to redirect this request to another web server (192.168.1.11 for example). I created a site "test" on IIS and it is displayed when test.ourdomain.com is entered. Then I tried to redirect it with following rule: Requested URL matches the pattern: * (using wildcards) Condition: {HTTP_HOST} matches test.ourdomain.com Action type: Rewrite Rewrite URL: http://192.168.1.11/{R:0} but when I try to load test.ourdomain.com now I get IIS's error 404 page. Obviously I'm wrong :-) How can I do such a redirect?

• Avast Antivirus downloading data from net even when told not to update.

  - by Nathan W

  Hi all, This is a strange problem that I have never seen before. I have two machines, both running Win 7 and running the latest version of Avast, both seem to be downloading large amounts of data. I noticed it when we were using more data for our monthly limit then normal, 2gb+ in a couple of days when really only browsing. I installed NetLimiter and let it run for couple of hours and this is the result for the avast! Service (c:\program files\alwil software\avast5\avastsvc.exe ). The other computer downloaded twice as much data in the same amount of time. Both installs of avast have their automatic updates (turned off at 4:00pm), for both program and definitions. Does anyone know what might be going on here.

• Simple SQL Server 2005 Replication - "D-1" server used for heavy queries/reports

  - by Ricardo Pardini

  Hello. We have two SQL 2005 machines. One is used for production data, and the other is used for running queries/reports. Every night, the production machine dumps (backups) it's database to disk, and the other one restores it. This is called the D-1 process. I think there must be a more efficient way of doing this, since SQL 2005 has many forms of replication. Some requirements: 1) No need for instant replication, there can be (some) delay 2) All changes (including schemas, data, constraints, indexes) need to be replicated without manual intervention 3) It is used for a single database only 4) There is a third server available if needed 5) There is high bandwidth (gigabit ethernet) available between the servers 6) There isn't a shared storage (SAN) available What would be a good alternative to this daily backup/restore routine? Thanks!

• Vagrant with VMware ESXi Provider

  - by Adam

  I am attempting to work with Vagrant and the vagrant-vsphere plugin to deploy machines to my VMware ESXi server. Has anyone had any luck in getting this to work? I realize that vagrant-vsphere is still 0.0.1 though and there are bound to be bugs. Specifially, Vagrant and vagrant-vsphere appear to fail during the vsphere connection, however, SSH and CLI access is enabled and the vSphere powershell is able to connect without an issue. INFO warden: Calling action: # ERROR warden: Error occurred: VagrantPlugins::VSphere::Errors::VSphereError The hostd log file on the ESXi server shows the Vagrant doing an SearchIndex query.

• OpenVPN Cloud for Network monitoring

  - by mezgani

  I'm working on a supervision project based on OpenVPN, a good way to send some network traffic through a secure channel to office from there out to the Internet. On office i have an OpenVPN server installed and i need to monitor all branches servers that are behind firewalls. I know that the point to point solution is very easy so we may only install OpenVPN client on node that i need to monitor. In the fact, is there any other issue that could help to supervise all branches DMZ network, without installing the client on each machines.

• UEC - Can the Cluster Controller and Storage Controller be seperate systems?

  - by Jeremy Hajek

  My department is implementing an Ubuntu Enterprise Cloud. I have done the testing and am quite comfortable with the 4 pieces, CC/SC, CLC, WS, NC. Looking at various documents below it appears the the Storage Controller and Cluster Controller (eucalyptus-sc and eucalyptus-cc) are always installed on the same system. My question is this: can I install the storage controller and the cluster controller on separate systems? http://open.eucalyptus.com/wiki/EucalyptusAdvanced_v2.0 the picture indicates that cc and sc are two different machines http://www.canonical.com/sites/default/files/active/Whitepaper-UbuntuEnterpriseCloudArchitecture-v1.pdf P.10 1st paragraph uses the word "machine(s)" http://software.intel.com/file/31966 P. 8 indicates the same separate architecture BUT... https://help.ubuntu.com/community/UEC/PackageInstallSeparate indicates below that the SC and CC are to be on the same system.

• DVI vs VGA on Windows 7

  - by Joe Philllips

  I have a 3 monitor setup (each monitor is exactly the same). Two videocards, each with one splitter (one DVI and one VGA). I have two monitors hooked up using DVI and the third is connected through the VGA connection. I am running Windows 7. If I resize a window from one DVI monitor to the other, it's not a problem. It does so very smoothly. If I resize a window on the VGA monitor it is extremely choppy. Why? It's not choppy on other machines with only VGA connections. Has anyone else noticed this?

• How to get Windows 7 to automatically connect to an ad-hoc network?

  - by George Edison

  I have two machines - one is running Ubuntu 12.04 64-bit and the other is running Windows 7 Starter Edition (32-bit). The Ubuntu machine is connected to the Internet via the eth0 interface. That machine also has a wireless network interface (wlan0) that is currently functioning as an ad-hoc network. I can connect to the ad-hoc network just fine with the Windows machine but each time I wish to do so, I must manually initiate the connection and enter the password. Is there some way to instruct Windows to automatically connect to this network (an option I have for standard wireless networks but not ad-hoc networks)?

• Getting around the lack of GPT support with CentOS 5.4

  - by sxanness

  Here is my issue and I hoping that there is someone out there that has an answer so I don't end up stuck here at my co-location all day. Last night I came here and upgraded a server (Dell 2970) to have four 1TB Hard Drives in RAID 5 which leaves a 3TB block. I tried to partition this but keep getting an error that GPT is not supported so I found a site online telling me I need to run the dd command and right random data to /dev/sda. This is great (if it works) but taking forever. I have two more machines to upgrade today and not a chair in site. Does anyone have advice on how I can avoid this issue beforehand? Thank You for your advice and support.

• Windows Server firewall asking for advice

  - by George2

  Hello everyone, I have Windows Server 2003/2008 machine, and I deployed some application on this machine. I want to put this machine in a sandbox environment, which means I want this machine to be able to access only proxy/gateway, its private used SQL Server database server, and I want to avoid network access from this machine to other machines in lab server room. Any easy solutions? BTW: my current environment is, I have a server which runs some Beta software in a Lab server room. It connects internet through proxy/gateway. Since the software is Beta, I want to reduce the risk of being hacked from internet and controlled by hacking sofwtare to attack my other servers in the same Lab server. thanks in advance, George

• How to prevent Ubuntu from combining networks on 2 NIC server?

  - by SolarPower

  I've got a Ubuntu Server 10.10 with 2 network interfaces with a cable plugged into both going to switches on completely different networks with different routers. One network is the 10.1.10.X network with a separate gateway/router - the server has an IP of 10.1.10.50 with the gateway IP of 10.1.10.1. The other interface is 10.2.10.X, IP 10.2.10.50, gateway 10.2.10.1. All my Mac machines are on the 10.2.10.X network, and all servers on the 10.1.10.X. The ONLY connection between the two is this machine. From a Mac in my office, I CANNOT ping any computer on the 10.1.10.X network except the Ubuntu machine I'm talking about. However, under the Shared column in Finder, I can see every server on the other network listed. That makes me believe that somehow this Ubuntu machine is letting certain requests span both networks, which is a security problem. Hope this is enough info.

• VirtualBox - split partitioned VDI into separate VDIs

  - by mathematical.coffee

  I'm very new to VirtualBox. I set up an Arch Linux VM and a Ubuntu VM (Ubuntu host), both sharing the same .vdi like so (I had in my mind a dual-boot situation): VDI file (25GB) |- /dev/sda1: 5GB (Arch Linux) |- /dev/sda2: [Ubuntu] |- /dev/sda5 (swap, 1GB) |- /dev/sda6 Ubuntu /, 9GB |- /dev/sda7 Ubuntu /home, 10GB I've now realised that I don't want a dual-boot-type setup, I'd rather boot each machine independently (my initial thought was to share /home between Ubunto and Arch). So, my question: Can I split /dev/sda1 and /dev/sda2 each to their own .vdi files so I can use them as completely separate machines? I'd rather not have to re-install either Arch (because it took me ages to work it out!) or Ubuntu (because I've already done a few GB of updates and don't want to redo them). I haven't been able to find anything about this - most questions I see are about converting a .vdi to a partition on the host, or splitting a .vdi into multiple smaller files (that are not independent), or converting a partition on the host to a .vdi file. cheers.

• How do I resolve active directory connection errors when using dcpromo?

  - by Middletone

  When attempting to promote a secondary server to an existing active directory forest I receive the following error message and can no longer continue. Failed to examine the active directory forest. Value ridMasterDSA.partentDN not found What can cause this and what can be done to fix it? Both servers are 2008 running on x64 and can see each other on the network via their names. FYI: The firewall is turned off on both machines so there should be no issue there. Also the server that i'm adding is already a part of the domain. One server is already a domain controller but I want to add a second to it.

• Enabling Multiple Monitor Support from Terminal Services/Remote Desktop over Citrix

  - by Nicolas Webb

  Our Remote Desktop/Terminal Services solution where I work relies on Citrix for machines not connected via the VPN. We're using Citrix Xen server (I'm pretty sure) and I'm going to try to connect to a Windows 7 Host (my work computer) and I think the RDC client runs on a Win2003 host (exposed via Citrix). Is it possible to take advantage of Windows 7 multiple monitor support for RDC with this setup? Would I need to try getting my Citrix guys to have a different host machine for the RDC (Win2008, or Win7?)? I'm probably going to connect using the OS X Citrix client, but I'd be willing to BootCamp/Fusion up a Windows instance to work remotely, as well. I really want to be able to use multiple monitors remotely. It does "span" multiple montiors currently (I have a 3000x1024 desktop, for example) but I'd rather it be "true" multiple monitor instead of one giant desktop, if possible.

• MS Word - Keeps requesting user to save Normal template

  - by MikeT505

  We have Small Business Server 2008 setup on a couple of our clients networks and we have the following issue. Whenever they logon, Microsoft word automatically opens and requests them to save their changes to the template 'Normal'. It constantly happens, we have a mixture of Win 2000 and XP machines and it seems to happen more often on XP than 2000. Any idea why this might be happening and how we can resolve it, it's just frustrating for the end users. PS: This is happening on Office 2000 and Office 2003.

• Sporadic '.Xauthority not writable, changes will be ignored' going from OSX -> Linux

  - by Kamil Kisiel

  Every now and then when users SSH from their OS X (Snow Leopard) workstation to one of our Linux hosts they receive the message: /usr/bin/xauth: ~/.Xauthority not writable, changes will be ignored Of course, their X forwarded applications will not work at this point. However, if they log out and log right back in again they do not get the message and everything works as expected. On their Mac they get their home directory via AFP. The Linux machines get it via NFS. Any ideas on what could be going on here?

• Automated testing in Android development

  - by Sara

  I have an ordinary project with JUnit tests that are connected to the classes in my Android Project. I want my server to run some JUnit tests in my testproject everytime I commit my code from my Android Project. Is there a best practise to do this? So far I only managed to run the tests when they are a part of a while the JUnit tests and Android classes are separated into 2 different projects, since JUnit runs on JVM and Android in an emulator on DVM (Dalvik Virtual Machine).
