• Prioritize file sharing capabilities in Windows Server 2008

  - by cmbrnt

  I've got a server running Windows Server 2008, and use it mainly for sharing files throughout the domain from a number of disks. It's running on VMware ESXi 4.0, in case that matters. My problem is that when I log in to the server to check user permissions etc, the access speed the files on the remote disks almost grinds to a halt. I havn't been able to measure the speeds, but I would guess it slows down to about 100kB/s as soon as I log in. This is on a gigabit network and the problems are equal for all users, even the ones connected to the same switch as the server. I've assigned 2 GB RAM to the server, and reserved it 1,5Ghz processor power. I don't have to do anything special on the server for this halt to occur. How can I make sure file sharing is prioritized on the server, so no matter what applications I'm using it will always make sure file sharing works properly? Could this be a VMware issue?

• Windows Server: Do I really need servers in remote locations?

  - by IMAbev

  I have one main site with several servers an a 2008/2012 environment. I have 4 remote sites that are physically close (a few miles apart) and are all connected to the main site by 20meg fiber on a private network. At each of the remote locations I have a windows server that users log in to and where their files and apps are located. There are many considerations to answering this question. But the first thing I am wondering is do I really need a server at each location? Users are just logging in to this server for permissions and a vast majority of my users are only using word, excel and email. I am really interested in figuring out if I need servers at these locations. $3,000 to $4,000 per server every 3-5 years, licensing, administration... I know there are other considerations - speed, redundancy, if my link to the main site goes down the users have nothing. But I just am not convinced I need servers at these locations.

• Destination host unreachable

  - by user1010101

  I have 2 router connected to 1 switch which contains two vlans, 1 router has the ip table of vlan1 and the other router have the ip table of vlan2 I have trunked both router cable to the switch. I have set 1 ip table per router which correspond to the ip address of the PC that have this router address as a gateway. When I ping from 192.168.100.2 to 192.168.200.2 it tells me that destination host is unreachable and the message is from the router 192.168.100.1. So I guess router for 192.168.100.x does not see the router for 192.168.200.x , right ? Or am I wrong ? What are good troubleshooting steps ? http://i.imgur.com/b94Ir.png is the representation of the network, i cannot post image since im not reputated enough.

• Preparing a hyper-v VM image

  - by Anteru

  We have a Hyper-V Windows Server 2k3, and we're hosting multiple VMs on it. However, right now, we always start the VM creation right on the server, i.e. when preparing a new Ubuntu image, I just install it into a new VM and set it up and when I'm happy we store the disk image. I wonder if there is a way to prepare a hyper-v image locally on my desktop machine instead? I'm running Windows 7, and I would love to be able to set up a VM so that we can copy the image over to the server and be done with it. This is for linux images only, and we definitely need the hyperv network integration. Is there a recommended way how to prepare hyperv images without running a hyperv instance somewhere?

• What if any free video player for windows can I set a custom frame buffer for streaming over the wifi?

  - by user268883

  I currently use DAUM PLayer (Pot Player) but I have problems streaming video to my laptop unless it is plugged into the network. An easy fix (so I thought) would be to find a player were I could adjust the cache / buffer so say 5 mins+ is read to the local Hdrive and then played from there... I can not work out how to do this in any player I have VLC, MPCHC and DAUM installed. All I want to do is increase the file buffer so X amount of the networkfile is copied to the local drive and then played... so all stuttering is stopped? How do I do this?

• Do any of the HP printers have implement printer sharing?

  - by BCS

  I've seen several (home grade) HP prints that have network port and allow connecting to them via that. However I haven't seen any way to use it without installing the printer specific drives. This seems a bit silly because I've seen printer sharing system (SMB I think) that didn't seem to need any printer specific software. My question is: Is there a way to use one of these with my printers? (I'm omitting the exact model in the hopes that answers for several models (or a resource that answers it for several models) will be given.)

• Azure Linux out of band managment

  - by faker

  I have a Linux (Ubuntu) virtual machine running on Azure. It seems like the only way to connect to it is via SSH. This is OK for normal operation, but what to do when something goes wrong (fsck waiting for user-input, new kernel doesn't boot, mis-configured network, etc.)? There is a grayed out "Connect" button in the management interface, and the help for it says: To access a virtual machine running Windows Server, click Connect and follow the instructions. Enter the password that was set when the virtual machine was created. The Connect button is not available for a virtual machine running Linux, but you can use your favorite SSH program to access it. I've read the documentation on the command line tools, but there is also no way to connect to it. Is there any way for me to get such a console?

• Masquerade traffic from certain source IP to VPN connection

  - by Shuo Ran

  Network Setup: 10.0.0.1 Router: to internet 10.0.0.70 Server: Ubuntu based server,default gateway is 10.0.0.1 10.0.0.51 PC I created a PPTP connection(interface: ppp0) on Server to a machine on the internet, what I want to do is route all the traffic from certain IP address(10.0.0.51) through the PPTP connection and then to the internet. What I did are: Set the gateway on PC(10.0.0.51) as 10.0.0.70 Enabled ipv4 forward on 10,0,0,70 Add the masquerade rule to iptable: iptables -t nat -A POSTROUTING -o ppp0 -s 10.0.0.51 -j MASQUERADE After that, it seems none of the traffic from 10.0.0.51 be redirected to ppp0, instead these traffic are still going through 10.0.0.1 directly. Any thoughts on it?

• Running suspicious X programs in GNU/Linux

  - by Vi

  What the most harmful thing can malware program started as separate limited user account do if it has access to the X server? Network and filesystem things are already considered by chroot and netfilter. It obviously can lock the screen and I will need to switch to other vt and kill it manually. Can it for example disrupt other GUI programs on the same X server (access to root terminal in nearby window)? I know that it is safer to run it in separate X server, for example, in Xtightvnc or even some virtual machine, but how dangerous is to just run it like other programs?

• trouble accessing mail server from outside domain

  - by cinqoTimo

  Our organization just moved our Website/Domain to a hosted VPS. We elected, for the time being, to keep our email (Exchange) running at our office. On our new VPS, we simply add a DNS record to redirect our mail to our on-site exchange server. This worked out well, as mail is coming and going with no problems. Recently, we ran across an issue when setting up outlook from outside of our office (Not on same network as exchange server). When configuring mail server address, it keeps prompting for credentials. Anyone got any ideas on why this is happening? Is our VPS not allowing Outlook to find our exchange server? If so, how can we bypass it?

• EC2 Windows 2008 VM import Not Working

  - by remack

  I am trying to upload a Windows 2008 SP2 server image to Amazon EC2, but once the process is complete, I can't connect to it. I had ops export a VMDK from our datacenter. The image appeared to have a fixed IP, so I loaded it in VMWare player and enabled DHCP. I uploaded it following amazon's instructions: http://aws.amazon.com/ec2/vmimport/ I start the new instance and try to RDP to the public DNS; connection fails. My two thoughts are: Loading it in VMWare player messed it up somehow, since the instructions say use an ESX image. The image they made me had the wrong network adapter type. The image has an Intel(R) PRO/1000 MT adapter using the E1G60I32.sys driver.

• Configure Linux server hardware buttons for soft reset or power cycle?

  - by Jakobud

  I have a small modest CentOS server at home. I run it headless because anytime I access it, it's always via SSH. Anyways, tonight it became unresponsive to the network. I could not connect to it to investigate. In this case, I have to hook up a keyboard and monitor to see the problem. I ended up just rebooting it. But after this experience, I was wondering if it's possible to configure the hardware buttons on the CPU case to perform a graceful reboot or graceful power cycle in Linux. Even though the server becomes unresponsive once in a blue moon, it would be nice to simply press a button and have it shutdown all services and gracefully reboot. Anyone know how this could be accomplished?

• SSH running slow on cygwin

  - by Robb

  I have a Windows XP box with Cygwin running and the SSH service. I'd like to use PuTTY to connect to it from other computers on the local network. PuTTY works fine and I actually get a relatively speedy login prompt. But anytime I do an 'ls' on the root directory ('/') it typically doesn't complete, like the command is hung. Other PuTTY sessions suffer as well, no matter what i'm doing (even just an 'ls' on my home directory might take awhile or not finish). It is like a deadlock occurred somewhere in the ssh/cygwin system. The root directory does contain the 'cygdrive' folder which is the contents of the host computer. Could this be causing the slowdown?

• Windows Media Player 11 fails to authenticate with proxy (ISA)

  - by Ed Manet

  We have some users who need to use a 3rd party site that embeds Windows Media Player streaming video into a web page. Our users go through an ISA proxy server to connect to the Internet. The browser has no problems accessing the site through the proxy. When Media Player loads, we get prompted for network credentials, but the authentication fails. If we set up Internet Explorer 8 to not use the proxy, Media Player has no problem. Media Player is configured to use the RTSP/TCP and HTTP protocols, but not the RTSP/UDP protocol. Is this necessary? Is there a registry key I can use to enable it? Is this more of a proxy server issue? The proxy guy says it's a desktop issue.

• Can't connect to web-server on local host behind NAT

  - by eyeinthebrick

  I got Ubuntu as host. I'm running a web-server on http://192.168.199.8:80. It is accessible from the local network, but when I'm trying to reach it by external IP, I go to my router's web-page. I arranged port forwarding on router for port 80 to my local IP 192.168.199.8. Unfortunately web-server is still unavailable via external IP. I checked whether the port is open via http://www.canyouseeme.org/. As it showed that the port is unavailable, I changed port used to 3659 (not forget to rearrange port forwarding rule). Although http://www.canyouseeme.org/ shows that port 3659 is open, I still can't reach my web-server. Where can the problem be?

• Server 2008 DHCP some clients not getting IP

  - by AdminAlive

  Today (after turning on the server from an extended power outage) some clients are not able to get IP addresses. Some clients work just fine. Win 7 and XP doesnt seem to matter. I have tried flushing dns, renew, disabling APIPA and even assigned a static IP. Even with the static IP it acts as if it isn't on a network. You can't ping anything. I have also tried resetting the TCPIP stack. The clients that work can ping the DNS and DHCP servers fine. Any suggestions? Thanks

• How to set up server to be accessed from mobile devices [closed]

  - by Kgrover

  I need to set up a server that will eventually be accessed from an Android application. I don't have experience with how to go about this, but I've seen MySQL servers (Amazon EC2). I would need to store data on the server remotely (again, from a mobile device) and fetch it to display. What would be the best kind of server to use? I'm guessing I would only need around 50 GB of space. Is it possible to use a network drive and set that up as a remote server with an IP address? I would need to upload and extract data through java on Android. This is my first question on ServerFault, and I'm not sure if it's the appropriate forum. If not, please redirect me.

• Name-based virtual hosting in Apache

  - by malvikus

  I'd like to set up name-based virtual hosting in Apache, but I don't have DNS name (local private network). Thus I want to get something like that: http://192.168.0.1/wiki - First virtual host - wiki. http://192.168.0.1/redmine - Second virtual host - redmine. As I suggest I can be achievable by using ServerName option in section of both vhosts. But in Apache documentation has no mention that I can use for FQDN IP-addr. Is it possible? How can I reach my wishes? P.S.: I want to share my sites on the same subnet only. Thus any who can ping me can enter http://my_ip/wiki and get wiki, http://my_ip/redmine and get redmine.

• Ubutu Server Edition: useful for the home user?

  - by D Connors

  My question is simple. What (if anything) does Ubuntu Server Edition have to offer to home users? This question is mostly out of curiosity really, but I like asking. I've got a home network set up here with some 6 to 7 machines (most Windows, one Linux). And I was wondering how useful would it be to have a dedicated computer in my house running Ubuntu Server full time. We've had an awful experience with file sharing so far, would it simplify file sharing/transferring? Would I be able to limit the internet bandwidth granted to each PC? Would I be able to monitor in/out internet traffic (both real time and monthly statistics)? Last, and most important, if I'm completely off as to what Ubuntu Server actually is, please say so. I am completely new to it.

• Where do I read more about building an architecture like Google has? [on hold]

  - by user107148

  I want to develop a program that watches and traverses a rather big network for data. This data should then be available to search through with my program, maybe through a web interface or something. My intuitive thought at the moment is to build an architecture kind of like the one Google has. One "front-end" (the Google Search page) which is essentially a regular web application and one "back-end" (which in Google's case traverses the web). Now for the hard part: If I decide to make such a system, how should communication be done between these parts? One idea I had is to use some kind of database that both the back-end and front-end can access, but then comes the issues of concurrent writes and reads. Another issue with just using a database to communicate is that it makes it hard to "notify" the other part when something changes. Let's say that I want the "front-end" part to push changes to the UI when a change is noticed in the back-end. Then the back-end would have to have some way of notifying the front-end of this.

• Cannot ping a VM from a Hyper-V host

  - by user1688175

  I am facing a weird situation in my network environment. My infrastructure looks like this: I have a D-LINK DIR-635 acting as my default gateway (192.168.0.1) A physical Windows 2012 Server (192.168.0.10) with the following roles: DHCP, DNS, AD DS and Hyper-V. A virtual Windows 2012 Server (192.168.0.50) which I intent to use as an IIS server (Role is not deployed yet). My virtual machine was able to get an IP address from the DHCP server and is working perfectly (I can ping the default gateway [by IP, FQDN or DNS Alias], the Hyper-V host and any site on the Internet (CNN.com for example). However I cannot ping the VM from my host. It says: Request Timed Out. Do you guys know what I might be doing wrong? Any support is appreciated! Thanks!

• Open source monitoring tool without sending data to "Their Server"

  - by hangu

  I trying to use open source server monitoring tool. I know there are a lot, but I couldn't find what I need.. the basic process of monitoring tool I used to use before was, 1) Install agent in my server which I want to monitor 2) The agent send data to "their server" 3) I can check the health of my server through web browser presented by them. What I need is, avoiding "Step 2". Are there any monitoring tool that I can use? I have Windows 2008 and Linux servers simple feature will be enough like (CPU, Memory, Network..) Thank you
