• Mounting share over VPN

  - by user1337

  I have a CentOS 5 web server which currently mounts a NFS export on my Mac OS X 10.7 laptop. It works great, except over VPN I can't get it to mount at all. I tried SMBUp but haven't been able to get it working even locally. It doesn't look like there's an easy way to install netatalk for CentOS 5. Even still, I'm not sure if that's the best way to do it. I tried using a GUI SSH client that can "mount a FTP disk" and it would work, except the files require root access and there's no external root access and the client can't elevate permissions. The basic thing I need to do is have the server be able to read the files off of my laptop, connected via VPN. The files are frequently updated (every 5-20 seconds) so I don't want to manually do that via SSH. Which protocol can work with both platforms and easily handle the latency introduced by VPN (and potentially mobile broadband)? Thanks

• How can I unobstrusively backup a few client's email?

  - by tladuke

  This is a small office. Our web/email server is a shared host. In the office we have a windows 2008 box up all the time that runs our NAS and a couple other services. I don't have access to the ISP admin stuff, but I assume it has cpanel or something like that. I can get access if I ask. I want to get email backed up from the server to our NAS without the users having to do anything. I suppose I could set up Outlook on that server with everyone's account, but that's a terrible idea, maybe (would sent mail. The boss uses outlook, but we have Apple Mail and Thunderbird clients too. I guess the important thing is that outlook look at the backups, so boss is happy. Then again, maybe it should be stored in whatever is the most portable format (that will work on NTFS) This is for about 10 users.

• IIS6 can't find site on local network

  - by chezy525

  I have a windows 2003 server with dual NICs running IIS6. I can access everything remotely, but the internal network can't seem to find the site regardless of which IP Address I try to go to. There are really several weird things that are happening here, but I'm going to limit this question to what I'm guessing to be the simplest problem (the solution to which I'm hoping solves other things as well): From the server itself, I can access the webpage using the primary IP address (i.e. http://192.168.1.2/index.htm), but not using the secondary IP address (i.e. http://10.10.10.2/index.htm). Self pinging both IP addresses works, and the "Web site identification" in IIS has the IP address set to "(All Unassigned)"... which I believe should bind both IP addresses to this site. I apologize if I'm not providing enough details about my setup, but at this point I don't even know what's relevant...

• How to manage large number of desktop VMs?

  - by symcbean

  I'm looking at the feasibility of providing remote access to multiple virtual machines. The VMs themselves will provide user desktops. To make best use of the available resources, I'd like the VMs to hibernate when the user disconnects. Which implies being able to start them up when a user connects. Ideally each user would 'own' a VM image - but if not then I'd require that the session was terminated. Obviously this would require the remote access protocol to be tied into the VM management. Is there anything out there to provide such functionality? (extra credit for open protocols! ;)

• Windows Server 2008 is stuck at "configuring updates - stage 3 of 3 - 0% complete"

  - by Chris

  This has happened the last two times I've done updates to this system, and I really have no idea what is going on. It is installing a only a month's worth of updates. It only responds to ping and no services are up, so I can't view the system remotely (I have to hook up a monitor to see this message). In the past I've just restarted the system at this point and it eventually finishes updating. I want to know what I can do to avoid this situation, how to diagnose what is going on, and how to get any kind of remote access during the updates. Edit: I can start the machine in safe mode (where I did nothing but backup some files). I restarted and it no longer tries to do a windows update, just goes to the desktop where everything seems extremely broken. I can click on some things, but not launch most programs. I guess all I can do at this point is do a system restore or something. Edit: Re-installed windows on this system yesterday. That's my usual solution to issues I don't feel like diagnosing, like this one.

• Simulate a DFS share for a user not on domain with a folder in path

  - by user223655

  I have a consultant whose computer is not on the domain and needs to access various network resources. Unfortunately while adding a computer to the domain is a difficult bureaucratic process (and would disallow much of his development software from even running given the domain restrictions), we can allow him to have credentials to access network resources. As such, he accesses various network resources via NET USE etc. without using DFS. There is one piece of software which requires him to have the same hardcoded path as other domain users but that path is a DFS path which he can't map (i.e., the software checks the path at runtime and will only run if it matches the registered path and will reject it in the context of using a DFS versus conventional machine path) I was wondering if there's some method to simulate the DFS path without actually using DFS. e.g., the path the software needs to see is "\ABC\DFS\software\app.exe" whereas the non DFS path is "\DEF\Software\app.exe" while I could make his hosts file point DEF to ABC, I'm not sure if I can somehow make it point there with the DFS "folder" as well are there any methods for this short of making changes to the AD to allow him to use DFS or add him to the domain (both of which are politically/technically challenging sadly)? Thanks guys

• How to forward http traffic through a specific network adapter.

  - by user18129

  i have the following scenario. Two laptops are connected via a router through the Ethernet ports. These two computers need to be able to communicate together. One computer also needs to access the internet through a different adapter (i.e. we will taking these two laptops two various sites where by the most common type of internet access will be wireless).In isolation all of the various adapters work fine (i.e. the internal network works fine, and the wireless connects to the internet). However,we try to turn on all of the adapters at the same time,the following occurs: If we bridge the two network connections together on the "Server" -The internet connection doesn't work through the wireless If we don't bridge the connections The internet connections don't work It seems like http traffic is trying to be sent through the Ethernet adapter (which of course is not connected to an internet connection). How can we solve this?

• Windows Vista to Windows7 upgrade

  - by Kalls

  I have a Windows Vista Home Premium and I tried installing SP2 on it and It prompted me to install SP1. Then it stopped working when I installed SP1. I don't have back up that I can use to restore it. When I use the Windows Repair mode I am unable to get access to few options none of which is working. I do have access to the command prompt. Is there way to restore this? If I am planning to upgrade to Windows 7 Home Premium what are the steps?

• Danger in running a proxy server? [closed]

  - by NessDan

  I currently have a home server that I'm using to learn more and more about servers. There's also the advantage of being able to run things like a Minecraft server (Yeah!). I recently installed and setup a proxy service known as Squid. The main reason was so that no matter where I was, I would be able to access sites without dealing with any network content filter (like at schools). I wanted to make this public but I had second thoughts on it. I thought last night that if people were using my proxy, couldn't they access illegal materials with it? What if someone used my proxy to download copyright material? Or launched an attack on another site via my proxy? What if someone actually looked up child pornography through the proxy? My question is, am I liable for what people use my proxy for? If someone does an illegal act and it leads to my proxy server, could I be held accountable for the actions done?

• DD-WRT with both https and sshd running in port 443

  - by Bruno

  I have a buffalo router with dd-wrt v24 SP2. After setting up the basic stuff, I enabled the https access to the admin page. Several days later, while setting up remote ssh, I changed the default port from 22 to 443. And now..well :) You got the picture :) I can ssh the router but I have no web access to it's admin page. Before rushing to a cold-hearted configuration reset, is there any way to change the ssh port from a shell? Or make dd-wrt accessible thru basic http?

• Taking user out of MACHINENAME\Users group does not disallow them from authenticating with IIS site

  - by jayrdub

  I have a site that has anonymous access disabled and uses only IIS basic authentication. The site's home directory only has the MACHINENAME\Users group with permissions. I have one user that I don't want to be able to log-in to this site, so I thought all I would need to do is take that user out of the Users group, but doing so still allows him to authenticate. I know it is the Users group that is allowing authentication because if I remove that group's permissions on the directory, he is not allowed to log in. Is there something special about the Users group that makes it so you are actually always a part of it? Is the only solution to revoke the Users group's permissions on the site's home directory and grant a new group access that contains only the allowed users?

• Safety concerns on allowing connections to MySQL with no password on localhost?

  - by ÉricO

  In the case of a Linux system, is there any security concern to let MySQL users with standard privileges (that is, not the root users) connect to the database with no password from localhost? I think that enforcing a password even for localhost can add a layer of protection, since, with no password the database access would be compromised if the SSH access is itself compromised. Considering that, would it be less safe to allow no password connection to MySQL than having the same password for SSH and for MySQL? I don't know if that is to be taken into account, but we also use phpMyAdmin to let users administrate their own database. I am asking because I kinda dislike having to put our database passwords unencrypted in the source or configuration files of our applications, where they can easily be leaked unintentionally. Since our servers are configured to run our applications as the Linux user the application belongs to, I was considering allowing no password from localhost as a simple solution. So, would that be a very bad idea or not?

• NTFS Folder has no owner, no permissions, can't be deleted

  - by winnt93

  Hi, I have a folder a 2003 member server which can't be deleted. Nothing has any permissions (domain admin and running up a cmd prompt as "nt authority\system" using psexec) - always "access denied". When I do a dir /q, the owner shows as "...". I've tried takeown.exe on the folder and also it's parent. The bad folder always reports "access denied". Also tried to reset using icacls, same thing. Explorer permissons has no sharing & security options or tabs. It works fine for other folders, even in the same directory. Bit stumped to say the least. g.

• Advice for outdoor wifi hardware and topology

  - by Robot

  I haven't setup any wifi networks other than an access point or two at any single location, so I'd like advice on how to setup an outdoor/weatherproof network in an area approximately 150 feet by 200 feet. The interesting thing is there are a pair of pools in the middle of the coverage area. Here is a picture: blue is pool, green is coverage area, yellow is building with wired access. Can anyone advise me on weatherproof APs, antennas and placement for best coverage of the pool deck? I've looked at the Meraki stuff, but I'm thinking it's overkill.

• Folder is not accessable, owner is not changeable. What should I do?

  - by Martin

  I'm facing currently a problem with a folder in windows 7, that is not accessable. Such a problem I had treated often in the last years on several pc's. But today the problem seems harder than the last times. In the past I get to grips with this by changing the folder owner and then modify the security settings. But this time it is not possible. If I want to set the owner, it says that I have no access for the change of owner. I already have tried to remove the folder by using the administrator-console, but this also print access restricted. What could I do. Do I have to start with PE and remove the folder? Are there alternatives?

• Word document can not open on user's system

  - by Malyadri

  I try to open a word document in my web application. It opens fine on localhost, but now I am publishing my web application on a server. Users that access the published web application (like http://10.0.23.57/StandardOperatingProcedure/Default.aspx) can not open the word document on their system. winword.exe opens on the server but can not open the word document. Access my system to author systems also same problem is coming. (Word document does not open on user's system. The word instance opens on my system.)

• Two domains accessing same folder

  - by Liam Quinn

  I've just taken a new role in a school and am still familiarizing myself with their network, how ever I have recently been given a task and I'm having a little trouble finding out the fundementals of it. I have an admin network/domain 10.49.x.x and a classroom network/domian 192.168.1.x both connect to a Proxy server 10.49.202.231/192.168.1.51. Each domain has it's own shared folders as you'd expect, files and software installs etc, how ever there is a folder "staff" on the classroom network that all the teachers on the classroom network can access. The users on the admin network would like to access this same folder. How do I go about making this happen?

• How can I password-protect a Mac shared folder on a Windows workgroup?

  - by Phillip Oldham

  We have a Mac-mini running 10.5.8 which already acts as a fileserver for our simple Windows (mixed XP/Vista) workgroup. The Mac-mini is on the same workgroup and the files are shared via SMB, FTP, and AFP. Basic file-sharing is working, and has been for some time. We'd now like to add an additional directory/share which can be secured by a password so that only a small number on the network have access. Is this possible? I've already tried creating the additional folder on the mac system, adding it to the shared folders, and limiting it to a specific "shared user", however it's not possible to log-in from an XP machine. Adding a sub-directory to the currently working share and giving limiting it's access to the shared user doesn't work either.

• running a web server with encrypted file system (all or part of it)

  - by Carlos

  Hi, I need a webserver (lamp) running inside a virtual machine (#1) running as a service (#2) in headless mode (#3) with part or the whole filesystem encrypted (#4). The virtual machine will be started with no user intervention and provide access to a web application for users in the host machine. Points #1,#2 and #3 are checked and proved to be working fine with Sun VirtualBox, so my question is for #4: Can I encrypt the all filesystem and still access the webserver (using a browser) or will grub ask me for a password? If encrypting the all filesystem is not an option, can I encrypt only /home and /var/www ? will apache/php be able to use files in /home or /var/www without asking for a password or mounting these partitions manually? Thanks

• Route a specific user's traffic via VPN but still allow local networking

  - by wbg

  So, I want to route certain traffic via a VPN connection and the rest via my normal Internet connection. I want to run several different programs and most of them don't support binding to a specific network interface (tun0 in my case). I've managed to send a specific user's traffic via the VPN following the answers given here: iptables - Target to route packet to specific interface? But unfortunately, when I run a server that connects to the Internet and has a web interface running on a local IP (127.0.0.1/192.168.0.*), all the Internet traffic correctly goes via tun0, but I'm unable to connect to the web interface from a local IP as a different user. When I log in as the VPN-ified user, I can access services running on local IPs, but other users/machines can't access any servers I start. Can anyone point me in the right direction?

• Windows 7: Use VirtualStore as user for own benefit?

  - by mfn

  I've researched a bit and came to the understanding that VirtualStore is part of the new UAC feature in Vista/W7 which is the file system part of the transparent data redirection and redirects write access to folders like program files to C:\User\<username>\AppData\Local\VirtualStore\ in lack of applications respecting the LUA principles. Now I'm interested if that kind of transparent redirection can also be used as a power to the user. Here's an example which comes to my mind: I install any kind of software to e.g. D:\Whatever\ThisAndThisApp\ and I set up things that, after initial installation, any write access to this folder is transparently redirected to e.g. D:\MyOwnVirtualStore\Whatever\ThisAndThisApp\file_only_writable_here.txt. Is this thinking too far or can I actually use that power of VirtualStore as a user on Windows 7? I'm using the Professional version of that matters.

• forward all ports via htaccess to new address

  - by user875933

  I have a chat server running on my local machine that listens to different ports. I want to use the sub-domain of one of my accounts to access it. I intend to manually change the redirect whenever my local machine gets a different ip address. So: chat.example.com:123 would redirect to dynamic.ip.address:123 I am trying to accomplish this with .htaccess and RewriteRule I have tried: RewriteEngine on RewriteRule ^(.*) http://dynamic.ip.address/ [L, R=302] but this doesn't work. When I try chat.example.com:123 nothing happens. When I input chat.example.com into the web browser, I get dynamic.ip.address Is .htaccess the right tool for this? I am using a simple web host that gives me ssh access, but not much more.

• Synchronizing the SamAccountName Property using Windows Azure Active Directory Sync Tool

  - by pk.

  Using this official documentation as a guide, I would expect the SamAccountName property to sync from my on-premise AD to Office 365. I think that it used to do exactly that, but now it seems that it doesn't so much sync the attribute as it does create an entirely new, unlinked value and store it in Office 365. This has caused some minor issues for me (broken scripts, annoying permissions management, etc.) and may be part of a more major issue regarding ADFS authentication. On-Premise PS C:\Windows\system32> Get-ADUser jdoe -Properties SamAccountName | fl SamAccountName SamAccountName : jdoe Office 365 Sync'ed Objects PS C:\Windows\system32> Get-Mailbox jdoe | fl SamAccountName SamAccountName : $1A7H20-K1LCOJFFBHGS I understand how to work around this issue in my scripts -- there exists the ImmutableId property which can be mapped back to the on-premise GUID. As far as the issue I'm having with ADFS, I'm less certain how to proceed and if this is causing my issues. At this point I really would just like some verification that I'm not crazy and that this used to be sync'ed at some point in the past and that Office 365 broke it relatively recently. I also think that MS documentation should perhaps be updated to exclude SamAccountName from the list of synchronized properties on the page I linked.

• Trying to install PHP 5.2 on IIS/Win 2008 - Error 500

  - by Razor

  I have a fresh install of IIS 7 - I just added Web Platform Installer, and PHP 5.2 thru that. However, when trying to access to a simple test.php file (just has phpinfo() in it), I get the following list of errors: • IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly. • IIS was not able to process configuration for the Web site or application. • The authenticated user does not have permission to use this DLL. • The request is mapped to a managed handler but the .NET Extensibility Feature is not installed. The domain was created with dot net panel, but I don't think that has to do with this problem, unless maybe it uses a specific user? Maybe I need to add php thruough dot net panel? Any idea of what I'm doing wrong here?
