  • Cyrus: In practical terms, how do end users administer their shared mailboxes?

    - by Nick
    Let's say we have four customer service reps: Billy, Bob, Joe, and Tom. Tom is the department manager. There's a shared Customer Service mailbox on the Cyrus server that they all have access to. Tom, as the manager also has administrative privileges for the shared mailbox. They decide they want to create sub-folders a certain way, and Tom creates them. They're all running Thunderbird, so Tom right-clicks the main folder and chooses "New Subfolder". Now Tom has the Subfolders he needs and the other sales reps have... nothing! Because Cyrus created the Subfolders giving Tom "Full Access" permissions, and everyone else gets no access. So how does Tom give the other reps in his department access to the new folders? As far as Cyrus is concerned, Tom has permission to grant others access to his new mailboxes- But as far as I can tell, there's no option in Thunderbird for granting mailbox permissions. An IT staff member should not have to receive a support request every time someone wants to add a Subfolder to a shared mailbox. That's why we make certain users into mailbox admins in the first place! But asking (non-technical) users to SSH into an IMAP server to run cyradm seems like a bad idea too. Certainly someone has found a solution for this dilemma. Perhaps a Thunderbird extension for setting Cyrus permissions? Or something like umask that forces subfolders to have identical permissions to their parents on creation? And related, what about Sieve configuration? Is there anyway that can be done from the client machine too? Thanks, Nick

  • Remote Mac OS X server using Windows 7 with VNC

    - by Ali
    I've search most of the topic around here in @SuperUser and around most of the webs they can easily access Windows uing Mac OS X but I have a question can I access my Mac using Windows? I've activate my screen sharing on my Mac OS X and I can use another Macbook to access it no problem but once I use TightVNC or UltraVNC and any VNC base program non of them really worked for me. So is there any alternative to VNC to give me option to access my Mac using VNC or something like that? Thanks.

  • IIS6 Permissions

    - by Gordon Carpenter-Thompson
    We have a set of IIS6 Jakarta/ASP.NET applications (implemented as virtual directories) on a machine without a domain. The directories all exist under the default website. We need to setup the permissions so that certain users can access only specific applications yet others users can access several of the applications. The way it's been setup previously has been to explicitly deny access to the users for every application except the ones that they are allowed to see. The problem is that the list of applications changes fairly often (for demos etc) and it's been known for the developers to forget to deny the old users access to the new applications which leads to security problems. This is all quite unmaintainable. Does anybody have any advice on this? Surely I can't be the only person to find this all a bit of a mess? Thanks

  • Hiding subfolders from users with Windows Server security

    - by Frans
    Using Windows Server 2008. I would like to allow all users to map to a common network drive and be able to browse it. But, I only want them to be able to see the subfolders they actually have access rights to. Is this doable? Example I have a share with two folders on it; \\domain\share\FolderA \\domain\share\FolderB With three different security groups, I would like to map a network drive for all three to \\domain\share. However, for group1, I want them to only be able to see FolderA, group2 should only see FolderB and group3 should see both. I am not just talking about denying access to the actual folder, which is easy enough, I don't want the user to even be able to see that the folder exists. In other words, when group 1 logs in and do "dir n:\" they should see N:\FolderA When group 2 logs in, they should see N:\FolderB and when group 3 logs in they should see N:\Folder A N:\Folder B My half-baked solution If I completely block access to the root then I can't map a drive to it. I can give everyone the traverse right which then allows the user to map a drive. However, if a member of group1 or group2 tries to go to "N:\" they get an access denied error. If they go to N:\FolderA (for group1) then it works. So, that sort of works, but it would be nicer if the user could actually browse to N:\ and just only see the subfolders they have access to. I am pretty sure I have seen this done but not sure how to do it myself. Any advice would be greatly appreciated.

  • Putting indexes in separate filegroup kills our queries

    - by womp
    Can anyone shed some light on this? On our dev boxes, our database resides entirely in the PRIMARY filegroup, and everything works fine. On one of our production servers, recently upgraded from 2005 to 2008, we noticed it was performing slower than it should. On this machine, there are two filegroups - PRIMARY and INDEXES. Both filegroups contain 1 file per logical volume, one logical volume per CPU, (and each logical volume is a RAID 10 of 4 physical disks). We isolated a few queries that were performing fast on the dev boxes and slow (up to 40x slower) on the production machine. Turned out these queries were using the non-clustered indexes that resided in the INDEXES filegroup. Tweaking some of the queries to only use clustered indexes that were in the PRIMARY filegroup dropped their times back to normal. As a final confirmation, we redeployed the same database on the same machine to have everything in PRIMARY, and things went back to normal! Here's the statistics output of one of the queries, run identically on the machine with different filegroup configurations (table names changed to protect the innocent): FAST (everything in PRIMARY filegroup): (3 row(s) affected) Table '0'. Scan count 2, logical reads 14, ... Table '1'. Scan count 0, logical reads 0, ... Table '1'. Scan count 0, logical reads 0, ... Table '2'. Scan count 2, logical reads 7, ... Table '3'. Scan count 2, logical reads 1012, ... Table '4'. Scan count 1, logical reads 3, ... SQL Server Execution Times: CPU time = 437 ms, elapsed time = 445 ms. SLOW (indexes split into their own filegroup): (3 row(s) affected) Table '0'. Scan count 209, logical reads 428, ... Table '1'. Scan count 0, logical reads 0,... Table '2'. Scan count 1021, logical reads 9043,.... Table '3'. Scan count 209, logical reads 105754, .... Table '4'. Scan count 0, logical reads 0, .... Table '5'. Scan count 1, logical reads 695, ... **Table '#46DA8CA9'. Scan count 205, logical reads 205, ...** Table '6'. Scan count 6, logical reads 436, ... Table '7'. Scan count 1, logical reads 12,.... SQL Server Execution Times: CPU time = 17581 ms, elapsed time = 17595 ms. Notice the weird temp table and extra tables involved in the slow query. It seems clear that having a second file group is making SQL Server batty with choosing an execution plan. What the heck is going on?

  • How should I set up my Hyper-V server and network topology?

    - by Daniel Waechter
    This is my first time setting up either Hyper-V or Windows 2008, so please bear with me. I am setting up a pretty decent server running Windows Server 2008 R2 to be a remote (colocated) Hyper-V host. It will be hosting Linux and Windows VMs, initially for developers to use but eventually also to do some web hosting and other tasks. Currently I have two VMs, one Windows and one Ubuntu Linux, running pretty well, and I plan to clone them for future use. Right now I'm considering the best ways to configure developer and administrator access to the server once it is moved into the colocation facility, and I'm seeking advice on that. My thought is to set up a VPN for access to certain features of the VMs on the server, but I have a few different options for going about this: Connect the server to an existing hardware firewall (an old-ish Netscreen 5-GT) that can create a VPN and map external IPs to the VMs, which will have their own IPs exposed through the virtual interface. One problem with this choice is that I'm the only one trained on the Netscreen, and its interface is a bit baroque, so others may have difficulty maintaining it. Advantage is that I already know how to do it, and I know it will do what I need. Connect the server directly to the network and configure the Windows 2008 firewall to restrict access to the VMs and set up a VPN. I haven't done this before, so it will have a learning curve, but I'm willing to learn if this option is better long-term than the Netscreen. Another advantage is that I won't have to train anyone on the Netscreen interface. Still, I'm not certain if the capabilities of the Windows software firewall as far as creating VPNs, setting up rules for external access to certain ports on the IPs of Hyper-V servers, etc. Will it be sufficient for my needs and easy enough to set up / maintain? Anything else? What are the limitations of my approaches? What are the best practices / what has worked well for you? Remember that I need to set up developer access as well as consumer access to some services. Is a VPN even the right choice?

  • Basic clarification about Limited FTP/sFTP users

    - by mattewre
    I would like to get some clarification about the correct way to create limited users to access to my VPS user as WEBSERVER with Nginix. I'm used to NOT install FTP and access via SFTP only. It is ok for every set up? this is what I usually do from to create a limited user called "admin" that should be able to have access via SFTP to the folder with the website data mkdir -p /var/www/mysite.com/ adduser admin adduser admin www-data chown -R root:root /var/www chmod -R 755 /var/www chmod -R 755 /var/www/mysite.com chown -R admin:www-data /var/www/mysite.com/ It seems not to be the correct way, I always have problems with permission when I upload some files (for example with Wordpress in general). I would like to create an user that does work exactly as the one that the "provides" give to their client when they buy an Hosting service (that is a FTP, I would prefer SFTP access). It is for personal user, but I think that a limited user is a lot safer to use then the "root" via SFTP.

  • Windows 2012 RDS Temporary profile for Administrator

    - by Fabio
    I've configured a Windows 2012 RDS Farm with two virtual servers (VMWare - each one on a different ESX server). Both servers have Licensing, Web Access, Gateway, Connection Broker and Session Host roles. High Availability is set up and it works fine. Remote Apps are working and even Windows XP clients have access to the web interface. User profile path is \vmfiles1\UserProfileDisks\App\ and almost everyone has full right access to it. The problem I have is that I would like to be able to access both servers at the same time with the Administrator account (console), but each time I try, the second server that I logon to give me access with a temporary profile. I tried to enable/disable multiple sessions per user and forced Admin logoff with the GPO but nothing changed. Another thing is that the server pool is not saved, so each time I restart the RDS server or I logoff from it, I have to add a server in the server manager. Do you have any idea? Sorry if my english is not perfect.

  • How can I use `SetEnvIf` to clear an Apache2 environment variable?

    - by Jamie
    In my apache2 configuration I've got these lines: SetEnv log_everything # Create the environment variables based on access requests SetEnvIf Request_URI "^/orders/.*$" download_access !log_everything SetEnvIf Request_URI "^/download/.*$" download_access !log_everything SetEnvIf Request_URI "^/wg/.*$" wg_1x1_access !log_everything # Log the accesses using the generated environment variable as conditionals. CustomLog ${APACHE_LOG_DIR}/download.log combined env=download_access CustomLog ${APACHE_LOG_DIR}/wg.log combined env=wg_1x1_access RewriteEngine on RewriteRule "^/wg/.+$" "/wg/1x1.gif" ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined env=log_everything Which currently logs all the "download" and "orders" requests to "download.log" and "wg" requests to "wg.log", but everything is also going to access.log. How can I configure this so that "wg" and "download/orders" requests won't be duplicated in access.log?

  • VirtualBox - multiple guests, each with a single bridged adapter?

    - by Martin
    I am running a dedicated server (located at Hetzner, Germany) that runs VirtualBox in order to virtualize several services accross multiple virtual guests. Those guests are supposed to communicate with each other (for instance, a virtual web server has to access a virtual database server); to be reachable from the dedicated server (for instance, SSH access); and to access the Internet via the dedicated server (for instance, to download security updates) Currently, this is achieved by having host-only adapter vboxnet0 on the dedicated server and two virtual interfaces on each guest. There, virtual adapter eth0 is attached to vboxnet0 (to achieve (1) and (2)), virtual adapter eth1 is attached to VirtualBox' NAT (to achieve (3)). Via eth0, the guests have access to a DHCP and a DNS server, both running on the dedicated server (there, bound to vboxnet0). This allows me to assign custom IP addresses and names. Via eth1, VirtualBox pushes a proper route that enables each guest to access the Internet (via eth0 on the dedicated server). This setup with two virtual adapters frequently leads to problems and at leasts complicates many things. For instance, on the dedicated server there is OpenVPN which allows to access the virtual machines via the Internet; futhermore, there is Shorwall that controls the incoming and outgoing network traffic between the Internet, the dedicated server, and the individual virtual machines. Not to mention automatic installation of servers via PXE... Therefore, I would prefer to have only one single virtual adapter on each guest which would be used for both incoming and outgoing connections. As far as I understand, one would basically use a bridged interface for that very purpose. Now the question arises: Which interface on the dedicated server would the bridge use? eth0 on the host server is not an option, as this is prohibited by the provider. A virtual interface eth0:0 would not make any sense, as a bridge always uses a physical interface (eth0 in this case). Would it be possible to create a bridged interface in each virtual machine that would "dangle in the air"? Thus, without a complement on the dedicated server? How would I have to set up the routing on the host server? Please note that the host / dedicated server has only one network adapter (eth0) which is connected to the provider's network. Regards, Martin

  • Microsoft Visual C++ Runtime error when viewing JPEG files in Explorer

  • OneNote can't connect to SkyDrive in Windows 8.1

    - by Greg
    Since I installed windows 8.1 I can't open my OneNote notebooks stored on skydrive with the 2013 Office OneNote app. When I click in the office app to open from skydrive it gives back: "We can't get your notebooks right now. Please try again later." I can open them without trouble in the modern UI onenote app, but I can't open password protected pages there. Also if I try to open it from a browser the error message follows: "We couldn't open that location. It might not exist or you might not have permission to open it." Neither can I create new notebooks on skydrive with the office app. "...The specified location is not available. -You do not have permissions to modify the specified location..." Can it be fixed somehow? Or can I at least save a notebook to my hard drive without opening it in office? The backup file got deleted with the win 8.1 installation.

  • Unable to specify parameters to cvlc in a script

    - by VxJasonxV
    I'm creating a script that issues a few curl commands in order to access a time-protected mms stream link, then set up a relay using cvlc (vlc's command line interface) for my own use on an unencumbered player. The curl aspect of this is working, as I can run as a browser and curl side by side and get the same access url. (It's time locked meaning the stream will work forever, but you have to connect quickly or the URL will time out.) The very end of the script prints the command I will run, which is then followed up by "exec $CMD". When I echo $CMD I get: cvlc --sout '#standard{access=http,mux=asf,dst=0.0.0.0:58194}' mms://[...] Manually Copy/Pasting this command in, verbatim, works perfectly fine, but as part of a script, the cvlc execution output says: [0x9743d0] main interface error: no suitable interface module [0x962120] main libvlc error: interface "globalhotkeys,none" initialization failed [0x9743d0] dummy interface: using the dummy interface module...

  • How to secure a directory in Apache using a PHP session

  • How to securely store and update backup on remote server via ssh/rsync

    - by Sergey P. aka azure
    I have about 200 Gb of pictures (let's say about 1 mb/file, 200k files) on my desktop. I have access (including root access) to remote linux server. And I want to have updateable backup of my pictures on remote server. rsync seems to be the right tool for such kind of job. But other people also have access (including root access) to this server and I want to keep my pictures private. So the question is: what is the best way to keep private files on remote "shared" linux server securely?

  • Configure Windows Routes for VPN

    - by Florin Sabau
    I have a Virtual PC/VMWare machine that runs Windows Server 2003. This virtual machine uses an IPSec VPN client program to connect to a remote network. I configured the virtual machine to have 2 NICs: NAT - to be used by the VPN Client to access the remote network Host only - to be able to access the virtual machine from the host The reason I have this setup is because I want to be able to access some remote network from the host machine. I could've installed the VPN client on the host machine, but the host runs Windows 7 and the client doesn't support it. The problem: although the virtual machine is normally reachable (ping + http access), as soon as the VPN client is started, neither of the NIC addresses are reachable anymore. I'm wondering if it is a routing problem that needs to be addressed? How do routing/VPN client connection affect the ability of the server to respond to client requests from the host?

  • Large keepalive_requests values are severely slowing-down Nginx

  • Limit copssh users to home directory Windows 7

    - by Siriss
    Hello all- I have found these two sites below: CopSSH SFTP -- limit users access to their home directory only and http://blogs.windowsnetworking.com/wnadmin/2006/11/07/copssh-restricting-users-access/ as well as the Copssh website, but upon completion they do not seem to work. I have copssh installed and I have a separate Windows account "sftpuser" created that is used to connect. The connection works just fine, but I want to limit that user to just their home directory and sub folders. I have 3 hard drives, the C:, a W: and an S: and I want the FTP account to only be able to access the W: drive and its contents (the root of the W: drive is the FTP home directory). Right now "sftpuser" can access all folders, including jump drives to C:, and S:. The linked tutorials do not seem to work, because it seems when I create a group "ftpusersgroup" and add "sftpuser" to the group, and then deny "ftpusersgroup" access to the C: drive, the service breaks and I can no longer login. I have undone everything and am ready to start fresh. Does anyone know how to do this, or is there a better tutorial that someone has or has found? I hope this makes sense. Thank you very much for any help!

    I've setup the web server successfully on Mac Leopard Server and sites work fine within the DocumentRoot directory. I have mounted a volume which has restricted access to users within a group. I would like to point the web server to directories within this volume. Can I add the user the web service is using to the group that has access to this Volume, if so: how do I find out what the user is? I can confirm the web server is pointing to the right directory as log files show the full directory path. When you access the site's URL, it shows Access Forbidden.
