• Need solution for Network/Servers.

  - by rehanplus

  Dear All, Please help me. I just joined a new Hospital and want some help managing my network. There are some requirements: Current Network: There is a D.S.L connection and that is terminated on a LINUX proxy and then connected to D-Link layer 2 switches and then providing internet to more then 200 PC's (Would be increasing to 1500 in couple of months). D-Link switches are not configured yet. Also there is one Database server Report server and an application server. In near Future Application should be accessed by local users as well as remote users from internet via our web server. We do have a sharing server and all these servers databases and PC's are on single sub net. Required Network: All i do want is to secure my network from outside access and just allowing specific users via web application and they will be submitting there record for patient card and appointment facility by means of application and entering there record (on our database) but not violating our network resources. Secondly in house users also need to access the same application and also internet but they must have some unique identity and rights (i.e. Finance lab dept. peoples do have limited access to that application). Notes: Should i create V LAN or break sub nets. Having a firewall will solve my issues? is a router needed on these type of scenario's. Currently all the access are restricted from Linux Proxy. Thanks.

• My Ubuntu 10.04 server kills all WAN bandwidth when it's attached to my LAN. Where do you begin troubleshooting?

  - by rrc7cz

  First I should say that my Linux knowledge is minimal; just enough to set up some servers (Apache, Tomcat, Couch, etc). I built a MiniITX server to host some simple sites, act as an SSH tunnel while I'm away, and act as a torrent server. It was not properly secured for a long time (iptables was empty, all ports open, no firewall) though my router did not have much port forwarding set up beyond HTTP, FTP, and SSH. A week or two ago my bandwidth at home dropped from around 27Mbps to 2Mbps and my upload went from 7Mbps to 0.06Mbps. When I unplug the server from the LAN, by bandwidth shoots back up. I threw up a restrictive iptables, removed most of the port forwarding, and checked my router logs to see if there were any open connections from the server (malware?) but there were none. What would you do? What are the first things you'd check? I can of course reinstall everything from scratch, but I'd like to find the root cause.

• Integrating external computer into a domain - some recommendations please

  - by TomTom

  Given: * A multi loation company. Every office has local routers that connect to a central VPN capable rouer in a data center. All fine so far. We now need to move a computer off site into a hosting center across the globe, to get it closer to some supplier computers we work for. it will run limited logic but latency is important, and our latency so far is too large. This computer will be in a data center and does no require incoming connections except for adminsitrative purposes, although it needs outgoing connetions. I have no real chance to put one of my VPN routers there, sadly - otherwise I would have no problem. Usage of RRAs is not recommended (we had various probblems there over time). I could deal with it. The computer MUSt integrate into the corporate structure via VPN and join the domain and be fully "tracked" (controlled for performance). What is the best suggestion? So far it looks like my best bets woudl be to log in via RRAS and deal with whatever issues arise there plus uise the local firewall the limit incoming connections to this computer to what is needed (which runs down to an emergency RDP connection allowance). Anyone a better idea?

• Can't connect to FTP server from a specific location

  - by wv_pip

  Last week while uploading website files to our server via FTP, the transfer failed. Ever since then, I haven't been able to connect to the server from work. I can connect just fine from home, or by using an FTP app on my cell phone as long as I'm on the cell network. I can't access the server from any machine on my work network. It's not a credential issue, either. The error message that I always get says that a connection cannot be established, and I am never prompted for my credentials. I have changed absolutely nothing on our domain controller or our firewall/router. I've contacted our ISP (who hosts the website/FTP server) and they can't find anything wrong on their end. They insist that it must be something here at the office that is blocking access. I've also tested access to other FTP servers (ea.com, nvidia.com, etc.) so I know that port 21 is not being blocked. I'm totally stumped. Any help is much appreciated. EDIT: wireshark info here: http://www.cloudshark.org/captures/85a118ae9296?filter=ip.dst%3D%3D66.118.64.208

• I'm having trouble getting my server to appear online.

  - by JMRboosties

  Total newb question I'm sure. First I had installed WAMP (http://www.wampserver.com), and I was able to access my pages from other computers in my router network, and the virtual device used to debug Android programs (the purpose of my having a server). This functionality failed, however, at some point over these past few days. While my own browser displays the pages just fine, other computers, my Android phone (on our room's wifi), and my virtual device are no longer able to connect to my pages. I had not made any changes in the settings. I uninstalled WAMP and installed EasyPHP. However, the problem was not resolved. I know this is rather vague, but does anyone here have an idea of what may have happened? I forwarded both port 80 (I know its the default HTTP port, I did it just to be safe), and now port 8888 which EasyPHP uses. I turned my firewall on my hosting computer off for good measure. I cannot access my pages from neither remote computers or computers using my router. Any ideas you may have on how to resolve this would be awesome, thanks a lot. And if you need anymore info please tell me.

• How do I change the default ftp folder in Mac OS X 10.6?

  - by Wild_Eep

  I'm running WordPress 2.9.1 from a Mac running 10.6.3. WordPress is installed to the /Library/WebServer/Documents folder. WordPress has a feature called Auto Update. Clicking an auto update button will download and install updated versions of the WordPress software, or third-party plugin tools. It's a convenient way to keep things up to date. WordPress uses FTP to download the files. I've enabled FTP and set up a user account and opened the requisite ports in my firewall for FTP traffic. This doesn't seem to be enough for my self-hosted installation, though. I'm sure this feature was originally designed for someone who has access to a remote shared webserver, and that it's merely a configuration challenge related to the FTP setup. I feel that if I can adjust the initial directory that the FTP service presents to the AutoUpdate feature, everything else will work properly. So, my question is, how do I adjust what folder is presented when a given user connects to a Mac running 10.6.3 via FTP?

• undefined reference to function, despite giving reference in c

  I'm following a tutorial, but when it comes to compiling and linking the code I get the following error: /tmp/cc8gRrVZ.o: In function `main': main.c:(.text+0xa): undefined reference to `monitor_clear' main.c:(.text+0x16): undefined reference to `monitor_write' collect2: ld returned 1 exit status make: *** [obj/main.o] Error 1 What that is telling me is that I haven't defined both 'monitor_clear' and 'monitor_write'.

• Random Windows application crashes on Windows Server Hyper-V Core 2012

  - by Marlamin

  We're having some issues with our Hyper-V Core 2012 R2 installation on a HP DL360G8. We have an identical server with Hyper-V Core 2012 (not R2) that does not have these issues. When logging off from the physical server/via remote desktop, we sometimes get this error: Configure-SMRemoting.exe - Application Error : The application was unable to start correctly (0xc0000142). Click OK to close the application. We've also once or twice seen a "memory could not be read" error mentioning LoginUI.exe (another Windows app in System32) but have been unable to get an exact description. It's rather worrying to get such errors on a fresh install of Hyper-V 2012 R2. Is this even anything to worry about? Things we've done: Memtest86+, no memory errors Checksummed the file that is crashing with the one in the verified correct ISO, files match Server firmware upgrade to latest firmware of all present hardware, no visible changes Remade the RAID5 array , no change Reinstalled a few times, no change Reinstall without applying Windows updates after, no change

• Windows 7 Drivers for Hp Tx2000 tablet Pc

  - by iceman

  Has anyone tried the new tablet features of windows 7 on the Hp tablet TX2001au : http://h10025.www1.hp.com/ewfrf/wc/product?product=3653674&lc=en&dlc=&cc=us&lang=&softwareitem=ob-77258-1&dest_page=product&os=4062 ? Hp has only Vista drivers and no Windows 7 drivers yet : link and link The main issues after installing Windows 7 is that the graphics card (Nvidia GeForce Go 6150) and the coprocessor are not detected.The latest 191.07 GeForce/ION Driver installer says that it cannot find any compatible hardware by the way, i still haven't been able to get Xp running on this . The Nvidia GeForce Go 6150 driver seems to be customized by HP !! If you install the laptopvideo2go.com/ drivers on Xp(after MS nags that it can't verify the publisher of the driver) , it shows the blue screen of death. Is there a way to debug the BSOD ?

• HyperV on Domain Controller or DC on HyperV?

  - by Michael Stum

  I want to setup a little fileserver/domain controller/sharepoint server. SharePoint shouldn't run on the DC directly, so I want to use HyperV. But I never used it before, so I wonder: Should I install the Domain Controller and HyperV Role and run 1 VM for SharePoint? Or should I run HyperV server and then 2 servers, one for SharePoint and 1 for DC? Usage is minimal with only 1 user. Hardware will be an Athlon II X3 with 3x2.9 GHz and 4 GB RAM. Operating System will be Server 2008 R2 Standard in all cases.

• Upgrade from Vista 32 to Vista 64

  - by Lance Fisher

  I just ordered a laptop, and it came with Vista Home Premium 32. I want Vista Home Premium 64 on it. I'm planning a reinstall. Does anyone know if my product key for Vista 32 will also work for Vista 64 for an OEM copy? As far as I know, I just need to get the 64 bit media. Is this correct? Thanks. Update The laptop is a Dell XPS M1330, and its hardware is supported. Dell would even sell it with 64 bit. However, it was significantly more expensive for lower specs, and I couldn't get it in red.

  Hi all, I am trying to figure out what is my current NIC firmware version. If I run the latest firmware upgrade from HP, I get the following: It doesn't tell me the current version. If I try to check it from Device Manager, I get this: That's the driver version, not the hardware firmware version. If I reboot the computer, I don't see the NIC firmware during the POST.. How would I go about finding the current firmware version... Thanks a lot! Toast

• Un-failing over a Cisco PIX 515e

  - by ABrown

  We had a power outage at our data center last week and when our dual PIX 515E running IOS 7.0(8) (configured with a failover cable) came back, they were in a failed over state where the Secondary unit is active and the Primary unit is standby I have tried 'failover reset', 'failover active', and 'failover reload-standby' as well as executing reloads on both units in a variety of orders, and they don't come back Primary/Active Secondary/Standby. The only thing in my arsenal that I haven't tried is driving to the data center and performing a hard reboot, which I hate to do. I have read How Failover Works on the Cisco Secure Firewall and it seems like this should be wicked straight forward. output of show failover on Primary: Failover On Cable status: Normal Failover unit Primary Failover LAN Interface: N/A - Serial-based failover enabled Unit Poll frequency 15 seconds, holdtime 45 seconds Interface Poll frequency 15 seconds Interface Policy 1 Monitored Interfaces 2 of 250 maximum Version: Ours 7.0(8), Mate 7.0(8) Last Failover at: 02:52:05 UTC Mar 10 2010 This host: Primary - Standby Ready Active time: 0 (sec) Interface outside (x.x.x.165): Normal Interface inside (y.y.y.3): Normal Other host: Secondary - Active Active time: 897045 (sec) Interface outside (x.x.x.164): Normal Interface inside (y.y.y.4): Normal Stateful Failover Logical Update Statistics Link : Unconfigured. output of show failover on Secondary: Failover On Cable status: Normal Failover unit Secondary Failover LAN Interface: N/A - Serial-based failover enabled Unit Poll frequency 15 seconds, holdtime 45 seconds Interface Poll frequency 15 seconds Interface Policy 1 Monitored Interfaces 2 of 250 maximum Version: Ours 7.0(8), Mate 7.0(8) Last Failover at: 02:03:04 UTC Feb 28 2010 This host: Secondary - Active Active time: 896925 (sec) Interface outside (x.x.x.164): Normal Interface inside (y.y.y.4): Normal Other host: Primary - Standby Ready Active time: 0 (sec) Interface outside (x.x.x.165): Normal Interface inside (y.y.y.3): Normal Stateful Failover Logical Update Statistics Link : Unconfigured.

I'm not exactly sure how to interpret that syslog data. Primary doesn't seem to even try to become Active. When I reload the individual units separately, my connections are retained, so it doesn't seem like I have a real hardware failure. Is there something I can query (IOS or SNMP) to check for hardware issues? Any thoughts? My IOS-fu is weak. Thanks for any help you might provide, Aaron

• Mac does not recognize wide screen

  - by DUKE

  I am using Mac OS X Lion 10.7.4 on my Mac mini, with Samsung monitor with default resolution 1360 x 768. My Mac mini is connected to Samsung VGA port by Apple mini port to VGA adapter. When starting, my Mac does not recognize the wide screen resolution and always starts in a 4:3 mode, (but it shows 1360x768 as the resolution in the settings). I have to do one of the following actions to bring my Mac to the wide screen resolution: (1) Changing to some other resolution and bring back to the default resolution. (2) Unplug the Apple mini port to VGA adapter and re-connect again. (3) Put the machine to sleep and wake it up again. I am using Ubuntu 12.04, (in a different partition) in the same hardware, but Ubuntu is perfectly recognizing the display.

• Cheap dvr media server

  - by Tester101

  I would like to build a new computer to be used as a DVR and media server. I am thinking of using mythtv as the DVR software, but short of that decision I am completely open to suggestions. Requirements: Must be cheap. Must have low power consumption (since it will always be on). Should be quiet. Should be small. I'm really not sure where to start with this project, and am open to any hardware/software suggestions. Is it possible to build a small quiet and cheap system? *Keep in mind I am working on this project because I am tired of Cable rate increases, but I can't imagine living without a DVR so cost is very important and I would like the system to be sub $200.00. The system also needs to handle the new digital broadcast system. Thanks for the help,

• Disable linux read and write file cache on partition

  - by complistic

  How do i disable the linux file cache on a xfs partition (both read an write). We have a xfs partition over a hardware RAID that stores our RAW HD Video. Most of the shoots are 50-300gb each so the linux cache has a hit-rate of 0.001%. I have tryed the sync option but it still fills up the cache when copinging the files. ( about 30x over per shoot :P ) /etc/fstab: /dev/sdb1 /video xfs sync,noatime,nodiratime,logbufs=8 0 1 Im running debian lenny if it helps.

• Ubuntu keyboard detection from bash script

  - by Ryan Brubaker

  Excuse my ignorance of linux OS/hardware issues...I'm just a programmer :) I have an application that calls out to some bash scripts to launch external applications, in this case Firefox. The application runs on a kiosk with touch screen capability. When launching Firefox, I also launch a virtual keyboard application that allows the user to have keyboard input. However, the kiosk also has both PS/2 and USB slots that would allow a user to plug-in a keyboard. If a keyboard were plugged in, it would be nice if I didn't have to launch the virtual keyboard and provide more screen space for the Firefox window. Is there a way for me to detect if a keyboard is plugged in from the bash script? Would it show up in /dev, and if so, would it show up at a consistent location? Would it make a difference if the user used a PS/2 or USB keyboard? Thanks!

• Problem using Polar Irda device in Windows Server 2008

  - by AngrySpade

  I'm attempting to use the Polar IrDA device with Windows Server 2008 R2 x64. Although they dont make explicit drivers for it, I figured the Windows 7 x64 drivers would do. http://www.polar.fi/en/support/downloads?product=&category=Software&documenttitle=Polar+IrDA+USB+Adapter+drivers&document=/gip/PKBStoGIP.nsf/web_cat/C225742500419A8AC2257458003D3F40 The device has a yellow warning icon in Device Manager. Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Is there anything I can do about this?

• Wireless networking on Gnome on Ubuntu 9 / 10

  - by WaveyDavey

  So here's my problem: I have some netbooks (ASUS eee, and ACER Aspire Ones) that I've been tasked to set up as kiosk machines, locked up tight for normal users. I am a command-line, server man, so this gnome malarkey is all a bit new to me. I found a lovely 9.04 kiosk livecd that installs and runs exactly as I want it to, but I can't get the wireless working. So I dropped on a full 10.4 distro, and wireless works straight out of the box (so hardware is good) - all I needed to do was right-click on the network connection icon, enter my SSID and password (WPA/WPA2) and away it went, perfect. Further investigation on 10.4 distro shows that /etc/networking/interfaces is virtually empty (just auto lo iface lo inet loopback in it), even after I have set up the wireless thru the gnome taskbar applet (is that the right word?). So where does gnome / ubuntu store the network settings to bring the blasted wireless connection up, and what do I need to do on the kiosk version to get wireless running?

• Plugging in USB flash drive only shows error 43, "Unknown device"

  - by Daren

  My friend saved by his works onto my flash drive which was detectable/openable, but ... The very next day, the drive wouldn't show up in My Computer and Windows gave him error code 43 (Unknown device). I tried others few systems that once detected his flash drive but the problem still persisted. I don't know whether or not his flash drive is damaged but when plug/un-plugging, there are still sounds coming out though. Tried solutions: On Vista Home Premium (his computer): Uninstalled -- Restarted computer -- Re-installed (ERROR 43) On Windows 7 (my computer): Uninstalled -- Restarted computer -- Can't install (ERROR 43) It seems that my computer (Windows 7) had the lastest drivers already but still can't detect it. Its a Kingston DataTraveller 101 (DT101) 8GB. Could unplugging the flash drive without clicking "Safely Remove Hardware" have caused the problem?

• Can't re-install OS on Asus Eee PC 1018P

  - by cornerback84

  My friend has an Asus Eee PC 1018P. It has no CD/DVD drive (neither does he have a USB CD/DVD drive). The OS wasn't working fine, so we decided to restore the system using the provided OS backup from HD. But mid way through the installation it was interrupted and the computer was restarted (not a hardware or software issue – we did it). Now we cannot run the backup and we also tried to install Windows 7 through USB, but as soon as we start to install the OS, it says that some device driver is missing. It turns out that the OS needs a USB device driver to continue. It has USB 3.0 – maybe that's why the OS needs the driver. I tried disabling 3.0 and enabling 2.0 but then it does not boot from USB drive for some reason. We are stuck with this. The backup doesn't run and when booting from USB, it says that it needs a device driver. Anyone has any idea what we could do?

• Proliant ML350 Won't Load Windows

  - by Mike

  I have a HP Proliant ML350 G4 running Windows 2003 Server Std Edition that will not load Windows on boot. It gave me a BSOD while running a recent Windows update and has not been able to boot since. The BSOD was a generic error, "Hardware Fault. Contact vendor." I am not getting any errors when the machine boots--it just hangs with a black screen when Windows starts to load. The machine will not boot into safe mode either--it gets stuck after beginning to load drivers. When trying to load the Windows recovery console I get the message that Windows cannot find any hard disks on the machine. This, despite having to load the driver for my storage controller. The HP Smart Start diagnostics finds no problems with my hard disks nor anything else. What should I try next? Mainly, I just want to be able to pull the data off my hard disks.

• Which Linux distro for Mac Mini?

  - by spoon16

  I recently received a Mac Mini and would like to set it up as a web server and git source server. I would like to learn Linux so am interested in setting up my Mac Mini with Linux instead of OSX. Here are the main things that I will be using the Mac Mini for. git Repositories (via Gitosis) build server (build projects in git repositories using commit hooks and run tests) simple websites (PHP) learning C++ in a non-Windows environment What distribution would you recommend? Please provide some detail in your answer so that I can make an meaningful decision. Because I am looking to use the mini as more of a server than a normal desktop machine I was thinking of Ubuntu Server, I'm not sure if that is over kill though given the hardware I am using.
