• Have I bricked my Sun V20z?

  - by David Mackintosh

  I have a small pile of Sun V20z computers. I was trying to update the SP and BIOS firmwares in order to bring them all up to the same standard -- mostly to get the updated (ie actually useful) SP functionality, and figured that I would just do the BIOS while I was at it. For three of the four computers, it worked perfectly. However after the BIOS update, the fourth system won't boot. I did this: batch05-mgmt $ sp get mounts Local Remote /mnt 10.16.0.8:/export/v20z batch05-mgmt $ platform set os state update-bios /mnt/sw_images/platform/firmware/bios/V1.35.3.2/bios.sp This command may take several minutes. Please be patient. Bios started Bios Flash Transmit Started Bios Flash Transmit Complete Bios Flash update Progress: 7 Bios Flash update Progress: 6 Bios Flash update Progress: 5 Bios Flash update Progress: 4 Bios Flash update Progress: 3 Bios Flash update Progress: 2 Bios Flash update Progress: 1 Bios Flash update complete batch05-mgmt $ platform set power state on This command may take several minutes. Please be patient. After an hour of waiting, it still won't start. The chassis powers on, but beyond the fans spinning up and the hardware POST of the drives, nothing appears to happen. So if I try to re-flash the BIOS (on the theory that maybe something went wrong): batch05-mgmt $ platform set os state update-bios /mnt/sw_images/platform/firmware/bios/V1.35.3.2/bios.sp This command may take several minutes. Please be patient. Bios started Error. The operation timed out. Have I bricked it?

• Can I change the file system on the OS partition on Server 2008 R2?

  - by KCotreau

  I have a client using R1Soft Continuous Data Protection backup, and two of the Server 2008 R2 boxes were erroring out with these errors: Unable to obtain NTFS volume data for device '\\?\Volume{f612849e-7125-11e0-8772-806e6f6e6963}': Incorrect function. Unable to discover information for filesytem volume '\\?\Volume{f612849e-7125-11e0-8772-806e6f6e6963}'; Unable to obtain NTFS volume So I backed up all the registry entries with this, {f612849e-7125-11e0-8772-806e6f6e6963}, in it, and deleted them based on some VERY sparse info from R1Soft. I then decided to restore them before I rebooted, and do a system state backup first using MS backup, and even it errored out saying that there were FAT32 partitions. This was a major clue as the only two computers with problems had these FAT32 partitions. I figured if MS backup can't backup something, any other program is likely to have problems. Also, now that I realized the servers had FAT32 partitions on them, the error referencing NTFS takes on more weight. The partitions on both servers have the label "OS", but on one of the computers, it is given a letter, but on the other not. So I am thinking if I just convert the file systems from FAT32 to NTFS, it may solve the backup problem. So the question is this: Can I just convert those partitions, and does anyone have any concrete knowledge of any major downsides, like the servers not coming back up (of course, I would do one at a time)? My thinking is that the answer is probably at least 95% no, but they are production servers, so I wanted to get some second opinions.

• SQL 2008 SP2 RsClientPrint ActiveX - "Unable to load client print control"

  - by Miles

  We recently updated our SQL 2008 server to use SP 2 and its causing a few headaches. We use SSRS on this server and when a client tries to print a report by the built-in print function, we're needing to download the RsClientPrint ActiveX control from the server from the client gets the following error Unable to load client print control. We have about 700 computers that are needing this fixed and I've followed the instructions found on the following URL: http://www.kodyaz.com/articles/client-side-printing-silent-deployment-of-rsclientPrint.aspx We have two issues: Most of the users who will be using this ActiveX control are not local administrators so they will not be able to install the control themselves Since there are so many computers, this has to be done silently behind the scenes run by a local admin account After following the information from the link above, we're able to put the files in the C:\Windows\System32 folder and register the DLL but we still get the same problem. The only small thing I've noticed is that in the HTML for the report page, everything that references a version is referencing version 2007.100.4000.00 and the version of the DLL that I pulled from the report server is 2007.100.1600.22. Also, for some clients that are local administrators, they are prompted every time to install the ActiveX control when they click print. This works successfully but we can't have the user asked if they want to install the same control every time they need to print.

• Ubuntu Server running VNC

  - by xwapilot

  I have access to four computers: 1 Ubuntu Server desktop (Version 10.04) 1 Mac Mini (Snow Leopard) 1 Windows desktop (Windows 7) 1 Windows laptop (Windows Vista) The first three will always be on the home network. My goal is to SSH from the laptop into the server and be able, through VNC (or another remote desktop software), to control the windows and mac computers. The goal of this would be a slightly heightened network security over using VNC to directly access the mac or windows desktop. I have successfully used SSH to connect to the server, but have not been able to successfully implement the remote desktop connection. I would appreciate help doing so. Here's what I've done so far: As per instructions here: http://www.stuartellis.eu/articles/vnc-on-linux/ I installed the following: vnc4server – the main VNC server software vnc-java – enables access from Web browsers with Java support xvnc4viewer – a basic VNC viewer I then set up a password using the vncpasswd command. To attempt to connect to the mac, I followed directions I found in a thread at superuser. com and went to "System PreferencesSharing" and enabled "Screen Sharing". Subsequently, I tried entering the following commands into Ubuntu: vncviewer mac_ip_address::5904 vncviewer mac_ip_address:0 vncviewer mac_ip_address:1 They all returned the following: VNC Viewer Free Edition 4.1.1 for X - built Apr 9 2010 18:41:55 Copyright (C) 2002-2005 RealVNC Ltd. See http ://www .realvnc. com for information on VNC. vncviewer: unable to open display "" I'm sure I'm missing something important, but I'm not sure what it is. Do I need to have a GUI installed, or did that come with the vnc packages I installed?

• Wifi Drops Connections with WPA2-PSK

  - by graf_ignotiev

  I run a small computer lab made up of 10 computers of identical hardware and software (Dell Latitudes with Windows 7 x64 Enterprise) and I use a ZyWALL 2WG as a router/firewall. Nine of the computers connect to the router over wifi using WPA2-PSK encryption while the last one is connected by ethernet cable. I'm having a problem where any computer connected to the wi-fi occasionally drops off the network (it cannot be pinged and the client cannot ping the gateway). It only happens on the wifi side and only when the encryption is WPA2-PSK or WPA-PSK. I tried using another router with a different make and model and had no problems. Thinking it could be a software error, I reset the router to factory defaults and installed the newest firmware (V4.04(AQI.8) | 04/09/2010), but still have the problem. The 802.1X log gives the following error User logout because of user disassociation. with this note WPA2-PSK:00242c582ece:logout where 00242c582ece is the mac address of the device. At this point I'm out of things to try and leads to follow. It looks like this user had the same or similar problem, but none of those proposed solutions work for me.

• Why did MAC-Adress Cloning Fix My Router?

  - by FranticPedantic

  I have a Belkin router, and about a year ago, I suddenly lost my internet connectivity from Comcast. The internet worked fine when I plugged it right into my laptop, so I just ignored it. When I moved to another apartmnet I eventually took the dive and called tech support. The tech told me to clone my MAC address which completely fixed the issue. Now I know what a MAC address is and I've read what MAC cloning is. What has bothered me since is that I don't see how this fixed the issue. As I have understood MAC address cloning, it has the router pretend it has the same MAC address as my computer. Here is why I don't understand why this fixes my issue: I have used several different computers with this router. Cloning the MAC address fixed it for ALL of my computers. The laptop I first used with my ISP was not the one that I eventually had connected when I cloned the address. Furthermore, I didn't have any problems for quite some time after I stopped using the first computer. It wasn't like the internet suddenly stopped working when I changed which laptop I was using Now it occurred to me that maybe there was some sort of expiration? Except... Which MAC address did it clone? It was just an option in the router administration page. Did it just pick whichever computer was connected to it? If my ISP still wanted the MAC of my first computer, how did some other computer's fix it? As mentioned earlier, why did this problem seemingly stem from nowhere? Anyway, I don't have any current problems so this is more just out of general curiosity. If anybody can explain it, it would be appreciated!

• Prevent Cisco VPN from interrupting home networking

  - by jkohlhepp

  I just got a new laptop, and for the most part have left its settings alone. Today I was trying to get some sharing going between my desktop and the laptop. Both machines are connected to the same wireless network and both machines consider that network to be a Home network. Both are running Win7 Home Premium. It seems like my laptop is aware of my desktop on the network. It can ping it by IP or by computer name. When I go to Network from the laptop, I can see the desktop in the list of computers. However, my desktop cannot ping the laptop, nor can it see it within Network. My desktop has a Homegroup set up, but my laptop says "There is currently no homegroup on the network". I do have network discovery turned on for both machines. Why can my desktop not "talk" to my laptop but it works the other way around? Update: Disabling the Windows Firewall on the laptop somewhat fixes the problem. With it disabled, my desktop can ping my laptop, but still my laptop can't see the homegroup. Also, it can ping via hostname, which resolves to IPv6, but can't ping via the IPv4 address. Obviously I'd rather not leave my firewall disabled, so I need a more specific fix. Update 2: Aha! It is the Cisco VPN software I was running to connect to work computers. Once I disconnected and exited from that, the two PCs seemed to be talking normally and the homegroup was visible to the laptop. So now my question has morphed: how can I prevent Cisco VPN from interrupting my home networking?

• System hangs while rebooting on Debian...

  - by Usman

  Hi, I have Debian (Kernel 2.6.26-2-686) installed on two computers. On one of them it reboots quite finely but I am having following problem with rebooting Debian on my second computer. When i type reboot at the Linux prompt, following messages appear and system hangs up after saying "Restarting System": Broadcast message from root@myname (tty1) (Sun Jan 17 11:23:26 2010) The system is going down for reboot NOW! INIT: Switching to runlevel: 6 INIT: Sending processes the TERM signal Saving system clock Stopping enhanced syslog: rsyslogd. Asking all remaining processes to terminate...done.

[ 31.789103] Restarting System. _ Normally when the sytem is busy "" sign blinks but "" at the last line above does not blink which shows, the system hanged up. I tried all keys but the screen is still frozen at the same point. The difference that I noted between my two computers is that I don't have ACPI support in the BIOS of the system which is giving me this error whereas the BIOS of my first computer do have ACPI support on which Debain do not give this restart-hanging problem. I have also disabled running the acpid script by running update-rc.d -f acpid remove but the problem still persists on the second computer. Any ideas to solve or get around this problem?

• Mac OS X L2TP VPN won't connect

  - by smokris

  I'm running Mac OS X Server 10.6, providing an L2TP VPN service. The VPN works just fine when connecting from all computers except one --- this one computer stays at the "Connecting..." stage for a while, then says "The L2TP-VPN server did not respond". In the console, I see this: 6/7/10 10:48:07 AM pppd[341] pppd 2.4.2 (Apple version 412.0.10) started by jdoe, uid 503 6/7/10 10:48:07 AM pppd[341] L2TP connecting to server 'foo.bar.baz.edu' (256.256.256.256)... 6/7/10 10:48:07 AM pppd[341] IPSec connection started 6/7/10 10:48:07 AM racoon[342] Connecting. 6/7/10 10:48:07 AM racoon[342] IKE Packet: transmit success.

So far I've unsuccessfully tried: rebooting deleting the VPN profile and recreating it verifying the client's internet connection (it is able to reach the VPN server) connecting through several different networks (in case a router was blocking VPN packets) disabling the Mac OS X Firewall on the client making sure that the VPN settings exactly match those of other working computers running software update (the client is on 10.6.3) Any ideas?

• AD server within another network - DNS issues

  - by Harry Muscle

  Here's a quick summary of the environment I support: we have a domain (domain A) that has about 20 client computers. The domain server for this domain and all the clients sit within the network infrastructure of a larger domain (domain B). All the computers get their network settings via DHCP from domain B's servers. I have no control and am unable to make changes to anything to do with domain B. The problem I have is that currently in order for my domain's (domain A) clients to be able to resolve the domain server and the shares on it they have their DNS server IP address set to domain A's domain server (via the default GPO). Unfortunately when a laptop (windows and mac) gets taken home, they are still looking for the domain server as their DNS server and obviously can't access the internet correctly outside of our environment. Ideally I need a solution where the machines use domain A's domain server as their DNS when inside the office and use what ever DNS server DHCP gives them when they are outside the office. However, since I have no control over the office DHCP server, I'm not sure how this can be accomplished. Any help and advice that anyone can offer is highly appreciated. Thanks, Harry P.S. The solution I'm trying to find needs to require no involvement from the user.

• OS/X 10.6 Bizarre login bug: Making alternative "Others..." appear. Why does this happen?

  - by bjornl

  I am studying at NUS in Singapore, and they have a mac-equipped computer lab here at school. All users (students) have our own personal accounts that we use to log in to the computers with. Sometimes when you approach a computer to log in only the alternative "thinkmac", which is the school's administrator account, I presume. Some other computers have the alternative "thinkmac" as well as "Others..." where you can input your own login credentials. One day as I sat down by a computer and there was only the "thinkmac" alternative. I was about to get up and find another one when the guy sitting next to me says - Just click 'thinkmac' - the computer will ask for your password - then hit escape to get back to the login screen. Repeat until "Others..." appear. So: If you click any user account, hit ESC to get taken back to the login screen, repeat for 5-10x, eventually the alternative "Others..." will appear. Why is this? Is there an internal counter that keeps track on how many times you have clicked a/any given user account, and after a certain threshold it displays the "Others"? What is the logical reasoning behind this?

• Clustering/load balancing for cluster unaware applications

  - by AaronLS

  Forgive me if I use any of these terms incorrectly. I am wondering if there is any kind of software that would allow my two "join" two computers together such that a cluster unaware application could utilize their combined computing resources? By "cluster unaware" I mean an application that isn't designed to share work across multiple services. My understanding is that clustering is enabled by the specific application by it's architecture, such that messaging with multiple instances of the application coordinate the sharing of work. Instead I am looking for something that enables clustering at the OS or virtualization level, so that any application could essentially be clustered. Failing that, I am also wondering about the following scenario: We have 3 different applications we will call A, B, and C. We have 2 single core computers. At any given time lets say that any combination of those applications will be CPU intensive. In cases where only 2 of those apps are very active, have one of them moved over to a different server. In a nutshell, some sort of dynamic automatic shuffling of the application's load. I have heard of virtual machines that can be migrated across physical machines while live, but I am wondering if this can be done automatically in response to an application's or VM's CPU activity?

• LogMeIn Hamachi for Linux

  - by tlunter

  So far most of my work using LogMeIn Hamachi has been from either a Mac OS X or Windows system to Windows or a Linux Computer. Recently I purchased a mini computer and have been running Ubuntu Server on it, as my little server. I knew LogMeIn had a Linux client that is command line only, but I often do all my work via command line anyway, so that wasn't an issue. I added my user to the correct local file so that I could run the hamachi daemon without sudo, and was able to connect to LogMeIn's service. I decided to set up my Linux server as a git server as well, and set it up correctly. The thing is, the server is behind my schools firewall and I need to use hamachi to get around that. Since most of the time I was using either Mac or Windows, I never had an issue sshing onto any of my computers since LogMeIn is fully featured for these OSs. From Linux (Arch) though, it seems like the client cannot correctly route to the LogMeIn IPs. I know from Windows I can connect to the Linux computers, both of them. From Linux (Arch) though, I can't connect to my Mac, Windows, or Linux server. It keeps just dropping the connection. I was wondering if there was some configuration that I would need to make for this to work. I understand that it is most likely going to be a static configuration since I assume it has to do with the computer not understanding that 5.*.*.* actually refers to another IP:Port. Has anyone had any experience getting this to work?

• Advice needed for a home network setup (hardware & software) to handle many clients and potentially heavy traffic

  - by posdef

  I have recently decided to re-structure the home network of our flatshare here. Here's a quick outline of the situation. I envision to have the following 4 devices connected to the router via cable: Xbox 360 IP phone Printer QNAP server (Web, File and Multimedia) We are three people living here, so on top of that there will be to 5-6 computers/mobile devices connecting as wireless clients. My goal is to be able to transfer files (when needed) between the computer and the Multimedia server, which I can reach via 360 and play on the TV. I also would like to keep a high level of security; right now I have the encryption on WPA2 and MAC filtering. I don't believe the web server will get heavy traffic, though I would like to have it responsive. Likewise, I don't have a habit of downloading via torrent etc, but I greatly appreciate my network being responsive and fast, especially when I am browsing or streaming high quality media. Now my questions are: is this setup feasible? smart? efficient? can this be improved somehow? my current router (D-Link DI624) and the previous one (DI-524) used to have spontaneous drops in network, which I find highly irritating. I don't believe in my router, especially now that it completely crashed when I was test-running the setup by transferring a large media file to server while xbox was playing music from the server, and two computers browsing the net. Do I need to get new hardware, if so, any recommendations for a reliable and fast router?

• why adding router will hide all share folders

  - by user1285419

  I have several computers running winxp installed in my office, they are all connecting to the WAN providing by the building (wall socket) (DHCP, mask 255.255.252.0). I setup a shared folder in my computer so all other computer in the same group could access it. This configuration have been using for long time. Recently, I am trying to setup a router. I have the WAN port of the router go to the wall socket, connect the NIC to the LAN port of the router, setup the router in DHCP mode (192.168.0.100/255.255.255.0 to 192.168.0.110 /255.255.255.0), I turn off all the firewall (windows one and router's builtin one), the NIC has ip set as DHCP. If I ipconfig/all, I see that the NIC was assigned ip 192.168.0.100. I can access the internal, email whatever. However, the shared folder can no longer be accessed by other computers in the same group. I think it is the problem of ip. But what's really weird is if I turn off the DHCP function in the router, ipconfig/all always give 0.0.0.0/255.255.255.255 and I cannot access the internet. I have no idea what's going on. Anyone know how to fix it and allow the shared folder in application of router? Thanks.

• DHCP Server on local machine

  - by EralpB

  Hello I am trying to setup a dhcp3-server on Ubuntu. But my question is more generic, if dhcp server is in a blockbox and all clients are connected to it I think I get what is going on but when dhcp server is installed on one of the "clients" that confuses me. When I send a dhcp packet from that client to the dhcp server, will my ethernet card read and write at the same time? Or will it handle it internally without writing any data to ethernet cable. It's the first time I am encountering these network things so I am a little bit confused. Also I wonder If I am in a big network with lan IP let's say 192.168.0.100 and I install a dhcp server to my computer, can any other computers accidentally get IP from my dhcp server? Every computer has one ethernet card (if that matters?). And every computer is connected to one router. I guess the answer is no because the broadcast message won't reach to my computer since when router receives a dhcp search packet it will answer and it won't let other computers know about it because they don't need to. And without router sending that packet one by one, it cannot travel further. I'd be glad if someone enlightens me. Thank you very much.

• How can I disable the CTRL-ALT-DEL key combination completely on XP/Vista/7?

  - by Travesty3

  I have been googling extensively to figure this out, and nobody seems to be able to give a direct answer. Let me start by saying that I'm NOT talking about requiring CTRL-ALT-DEL to enter logon information. I'm working on a golf simulator program which is used at golf centers. I need the ability to completely disable the CTRL-ALT-DEL key sequence so that the golf center customers can't get out of the program and access the computer at all. I realize there are other key combinations that need to be handled as well, we already have this entire feature working in XP, but we're going to be switching to Windows 7 soon, and CTRL-ALT-DEL is the only one that doesn't seem to work in Win7. I'd really like an all-around solution if at all possible. This same program may also be installed on a client's personal computer for an in-home golf simulator, but the computers that really need this feature (golf center computers) are provided to the golf center by us, so would the best option be to write a new shell? I don't know anything about that at all, other than others that suggest writing a new shell for kiosk mode. I'd really like a simpler option, like modifying the registry in some way. I have heard that you can remove some buttons from the menu screen that pops up, but unless I can remove pretty much all of them (including the shutdown/restart button in the bottom-right corner), this won't be enough of a solution for me. Thanks for taking the time to read this and thanks again for any help you could provide! -Travis

• How to prevent getting infected by rogue security applications

  - by Ieyasu Sawada

  My computer never got infected with a virus before, because I'm using Web of Trust browser plugin, sandboxie and Avast Free antivirus. But today, it got infected with a rogue security application called antivirus.net. I have already removed it using MBAM, SAS, and Kaspersky Virus Removal Tool. And by the way, I was using MSE when my laptop got infected. Seems like the rogue application just killed off the MSE process. And I never even got a warning. I was using the wi-fi from our school, which I think is the cause since most of the computers in our laboratory has rogue applications on it. My question is, how do I prevent this from happening again? It took me about 6 hours to disinfect my computer and I don't want it to happen again. Please enlighten me if these rogue applications really just pop out of nowhere. Note I'm not dumb enough to agree with installing rogue security applications. It just came out of nowhere. I'm happy with MSE, well not after it let antivirus.net penetrate my computer. I've done a little bit of research and it says that it needs the permission of the user to actually install it in the computer: http://www.net-security.org/malware_news.php?id=1245 http://en.wikipedia.org/wiki/Rogue_security_software Is it possible that other computers in our school network have agreed to install those? Or maybe the network admin?

• IIS6 intranet site using integrated authentication fails to load when accessed externally

  - by maik

  I've developed a couple of internal sites for my organization that use integrated authentication. Ultimately we want these sites to be accessible externally to users with domain-joined computers. The sites work as expected on domain computers while on the internal network. The problem comes when I take my laptop home and try to access those sites. IIS only has integrated authentication enabled for the two sites. When I browse to the site using IE8 I get a username/password prompt asking for domain credentials. I can put those in and it will work, but the goal is to use the cached token for integrated authentication. Next I reasoned that IE wouldn't response to an integrated auth request (is NTLM the right term for this?) unless the site was trusted. I tried adding the site to Trusted Sites but I get the same behavior as the before. I then added the site to Local Intranet sites and that is where things get weird. I get a generic error page from IE, no error code or anything. Just for funsies I loaded up Firefox (which I had previously set up to use integrated authentication) and I added this new site to network.automatic-ntlm-auth.trusted-uris. Much to my surprise I was able to load the pages up with no problem at all and saw exactly what I was expecting (including verification that the integrated authentication worked). My mind is a bit boggled at the moment as I'm not really sure where to go from here. I was hoping some of you may be able to provide some insight.

• Servers in DMZ will not communicate with each other

  - by Tukaro

  (Full disclosure: I rate barely above "noob" when it comes to networking.) My workplace recent got a new web server. Since we're nearing the end of an overhaul of our website, we're doing a slooooow migration between the old web server and the new one. The old webserver (we'll call it SERVOLD) is Windows Server 2008 with IIS 7. It does not have SQL Server installed. The new server (SERVNEW) is Windows Server 2008 R2, IIS 7.5, with the same version of SQL Server installed. Both are located in the DMZ for our network, and both have their own outward-facing IP address (.3 and .4, respectively). Each server can communicate fine with computers within the domain (not in the DMZ), and those same computers have no trouble communicating with either server. Both servers are also accessible from the internet just fine. However, no matter what, these two servers just refuse to recognize each other. They have the same Workgroup name listed (WORKGROUP), and I thought that would be enough for them to recognize each other. What needs to happen such that I can get these two servers to communicate with each other? We want to do a gradual roll-over to the new website (new one uses ASP.NET, old one uses CFMX), so being able to use one database between both servers is a necessity. Thanks!

• Windows 7 Can't Connect to Network Drive on Windows XP

  - by Alex Yan

  I have a Windows XP desktop and a Windows 7 laptop both connected to a TrendNET TEW-432BRP router, which is connected to the Internet. They both have static IPs. The desktop has an external hard drive connected to it. The laptop is wireless and the desktop is wired. I enabled sharing on the external hard drive about two years ago when I bought it. I mapped it as a network drive on the laptop. I think it was yesterday, the laptop just stopped recognizing any of the computers on my network (When I open network, my laptop's the only one on it). I also get an error message "An error occurred while connecting A: to \CERTIFIED-DATA\Expansion Microsoft Windows Network: The network path was not found. The connection has not been restored" when I try to connect to the network drive. Both computers run Avast, and there hasn't been any problems with it. This has happened before but I never figured out why and how to fix it. It's usually fixed when I reinstall the OS of the affected system. Edit: I can't navigate the computer using \\CERTIFIED-DATA. I get a message saying "Windows cannot access \CERTIFIED-DATA. Check the spelling of the name, Otherwise, there might be a problem with your network" I clicked diagnose on the message and it failed to find anything wrong I clicked diagnose on my wireless connection, and it just keeps trying to check if something is wrong with the connection I can ping it successfully

• Basic OpenVPN setup

  - by WalterJ89

  I am attempting to connect 2 win7 (x64+ x32) computers (there will be 4 in total) using OpenVPN. Right now they are on the same network but the intention is to be able to access the client remotely regardless of its location. The Problem I am having is I am unable to ping or tracert between the two computers. They seem to be on different subnets even though I have the mask set to 255.255.255.0. The server ends up as 10.8.0.1 255.255.255.252 and the client 10.8.0.6 255.255.255.252. And a third ends up as 10.8.0.10. I don't know if this a Windows 7 problem or something I have wrong in my config. Its a very simple set up, I'm not connecting two LANs. this is the server config (removed all the extra lines because it was too ugly) port 1194 proto udp dev tun ca keys/ca.crt cert keys/server.crt key keys/server.key # This file should be kept secret dh keys/dh1024.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt client-to-client duplicate-cn keepalive 10 120 comp-lzo persist-key persist-tun status openvpn-status.log verb 6 this is the client config client dev tun proto udp remote thisdomainis.random.com 1194 resolv-retry infinite nobind persist-key persist-tun ca keys/ca.crt cert keys/client.crt key keys/client.key ns-cert-type server comp-lzo verb 6 Is there anything I missed in this? keys are all correct and the vpn's connect fine, its just the subnet or route issue. Thank You

• Password-protected sharing allows access to users who have no account?

  - by romkyns

  Running Win7 on two computers in my LAN. Computer A has password-protected sharing enabled, and shares a folder. It has a single user account "Bob", and the Guest account is turned off. The network is workgroup-based. According to the descriptions of the "password-protected sharing" I could find, the only people who can access the shared folder via the LAN are those who know the username+password for the "Bob" account. However a second computer on the LAN is able to view this shared folder by simply browsing to Computer A. They don't need to enter any passwords or anything. The only user account registered on that PC is called "Jim", and has a different password from "Bob". How on earth is computer B able to view this shared folder? Is the popular description of the "password-protected sharing" feature inaccurate / did I misunderstand it big time? P.S. There is a possibility that the password for "Bob" has been entered on that PC once, and possibly the "remember password" box was checked. I've looked in the "Credential Manager" on both computers and there is nothing saved anywhere.

• Setup.exe called from a batch file crashes with error 0x0000006

  - by Alex

  We're going to be installing some new software on pretty much all of our computers and I'm trying to setup a GPO to do it. We're running a Windows Server 2008 R2 domain controller and all of our machines are Windows 7. The GPO calls the following script which sits on a network share on our file server. The script it self calls an executable that sits on another network share on another server. The executable will imediatelly crash with an error 0x0000006. The event log just says this: Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Setup.exe because of this error. Here's the script (which is stored on \\WIN2K8R2-F-01\Remote Applications): @ECHO OFF IF DEFINED ProgramFiles(x86) ( ECHO DEBUG: 64-bit platform SET _path="C:\Program Files (x86)\Canam" ) ELSE ( ECHO DEBUG: 32-bit platform SET _path="C:\Program Files\Canam" ) IF NOT EXIST %_path% ( ECHO DEBUG: Folder does not exist PUSHD \\WIN2K8R2-PSA-01\PSA Data\Client START "" "Setup.exe" "/q" POPD ) ELSE ( ECHO DEBUG: Folder exists ) Running the script manually as administrator also results in the same error. Setting up a shortcut with the same target and parameters works perfectly. Manually calling the executable also works. Not sure if it matters, but the installer is based on dotNETInstaller. I don't know what version though. I'd appreciate any suggestions on fixing this. Thanks in advance! UPDATE I highly doubt this matters, but the network share that the script is hosted in is a shared drive, while the network share the script references for the executable is a shared folder. Also, both shares have Domain Computers listed with full access for the sharing and security tabs. And PUSHD works without wrapping the path in quotes.

• mount nfs subdirectory and still apply parent directory permissions

  - by Christophe Drevet

  A NFS server exports : /export/home computers /export/cont1 computers On the filesystem, there are these permissions : $ ls -al /export/cont1 drwxr-x--- 6 root group1 4096 2010-05-04 10:57 . drwxrwxrwx 5 root root 4096 2010-05-07 14:52 .. drwxrwxrwx 2 root root 4096 2010-05-06 20:33 .snapshot drwxr-xr-x 2 user1 group1 4096 2010-05-04 10:57 user1 drwxr-xr-x 2 user2 group1 4096 2010-05-04 10:57 user2 drwxr-xr-x 2 user3 group1 4096 2010-05-04 10:57 user3 So that user4, which is in not in the group1 can't access this directory and its subdirectories. Now, on its client machine, this user can do : $ sudo mount server:/export/cont1/user3 /mnt/temp and then access the directory without permissions on /export/cont1 : $ id uid=7943(user4) gid=7943(user4) groupes=1189(group4) $ ls -al /mnt/temp/ drwxr-xr-x 3 user3 group1 4096 2010-05-04 10:57 . drwxr-xr-x 7 root root 4096 2010-05-04 11:02 .. -rw-r--r-- 1 user3 group1 6 2010-05-04 10:56 README Is there a way to apply /export/cont1 permissions even if it is not mounted ? The goal is to enable users to mount /home/user3 and only access it if they can access /export/cont1 on the nfs server. Said in another way : how can I allow a machine to mount /export/cont1/user3 and still don't allow user4 to access it. Maybe NFSv4 and Kerberos can help ?
