• How to forward traffic using iptables rules?

  - by ProbablePattern

  I am new to iptables and I have been doing Google searches for a few days now without finding a good solution to this problem. I have computer A with a public ip address (say 192.0.2.1) that can access the Internet unrestricted. I have another computer B with a private ip address (192.168.1.1) that can only access computer A. How do I use iptables to forward network traffic from B through A to the Internet? I need to use http, ftp, and https in order to use apt-get with sudo. Both computers run Ubuntu linux. I have tried using Squid but I think it is far too complicated for what I need to do.

• Windows NLB + IIS - Stops serving pages

  - by Ye Ol Developer

  We are currently running Windows NLB and IIS7 load balanced across two servers. What happens is randomly and sporadically the servers stop serving web pages. What we have noticed is that if we run the sites on a dedicated IP on either of the servers, these issues do not exist. As soon as we switch back to the load balanced IP, then everything goes awry. When the servers stop serving pages, we can still TS into the server and surf them internally without issues, or switch to the dedicated IP. However the internal network cannot even access the files from the load balanced IP. We are running out of idea's here. Has anyone had a similar problem?

• KVM guest storage difference with NBD and NFS

  - by WojonsTech

  I am setting up my own little private cloud for my own use maybe for a project or to. I am using linux kvm on debian 6. I have 3 servers 2 of them for compute nodes and 1 storage node. I would I have already installed kvm made a few test machines got my networking setup. I have 2 nics on each server 1 nic is for web traffic other nic is for network traffic. My first Idea was to use NFS for storing the guest machines which can range in size, maybe 8gb maybe 100gb, it just depends. I was doing have heard of nbd before seems like it could work but I dont know what the performance differences are and if it will effect my enviroment, nfs looks like it will be easier to use.

• Does connecting to the default host via public IP from within its subnet cause any issues?

  - by username

  I'm setting up a small office network with a single public IP (let's say it's 69.16.230.117). I've configured NAT on the router with incoming traffic forwarded to the server (say the server has a private IP of 192.168.0.2). Is it okay to configure the client machines on the same subnet to access the server via the router's public IP (69.16.230.117)? In practice it's never caused me problems, but I've heard, here and there, that it is a bad idea, and one should use the private IP (192.168.0.2). Does connecting to the default host via public IP from within its subnet cause any issues? Please refrain from writing "never! it breaks the intranet!" ;-)

• How do I justify to my management that we need a bandwidth upgrade?

  - by Sandeep

  I work in an office with a 8mbps line and about a 100 people. Our internet has slowed to crawl over the past few months, as we added headcount. However, using speedtest.net or other sites, still shows bandwidth as 8mbps. Now, how do I justify to management that we indeed need to upgrade our bandwidth ? Please note that I dont have access to our main routers or any network equipment. I can only use my system (windows+linux dual boot) to make a case for a reasonable justification. help!

• Very small image for rebuilds

  - by Deon

  I worked at a place last year that had a very small image for Windows XP re-builds. It was two Norton GHO files, totalling about 2-3 GB. This is how it worked: Boot into Norton Ghost Map to the network share where the images lived Apply the image to the workstation Reboot It would then load into Windows Setup Enter the Domain Admin credentials so it can join the domain That's it... it would then reboot into Windows and the image was complete. How did they make an image so small? Did they perhaps kick off a Windows install and create an image then? I particularly liked how it required no user input other than a domain admin login.

• Junk host name while using nslookup, How to change it?

  - by Jayachandran

  Hi, My question is regarding the host name mapped to a machine's IP. I am new to Linux, I have a machine to test whether our j2ee based web application runs fine in linux box. we are able to deploy our application and successfully and even able to access the same in that machine. But when I tried accessing it through another machine in the same network, I am not able to access the URL using the hostname specified, instead I am able to access if I provide the ipaddress. I tried putting nslookup MyIP# command to know the name of the ip in the DNS server, where I got some junk value.com; when I tried to access with that name I am able to access the machine. Kindly provide me inputs to change the hostname of this machine in that domain server. Thanks in Advance!! Jay

• Windows W8, L8 and now H8

  - by raccoon_tim

  Windows 8 is having to endure with a lot of headwind at the moment. The weather forecast doesn’t appear to improve in the near future either with prominent game developers and publishers taking to the barricades accusing Microsoft of building a closed ecosystem. I am forced to side with this opinion as I too see services the likes of Steam as playing an important role in the gaming world, which just happens to be an industry that cannot be sidelined. What Microsoft is attempting to do is merge the PC and mobile markets. The Windows Marketplace is to be the only place where you can purchase Windows applications in the future starting now with Metro apps. This is what Apple, Google and Microsoft have been doing with mobile devices for some time now and it’s what we have all come to expect. The PC market is different, however. It has always been open, which has resulted in a diverse market allowing for third parties to build successful distribution and marketing networks. You could argue that Microsoft is just doing something that Steam has been doing for a long time now but the difference is that Microsoft would own both the marketplace AND that operating system, which would eventually give it dominance over the whole Windows application distribution network. Currently there is no real alternative to Windows in the PC gaming world but I would expect to see Mac OS and Linux getting more popular if Microsoft does not notice the signals coming from the gaming industry and choose to once again open up the markets on the PC.

• Cannot open mailbox

  - by AdamL

  Ive got a server running Windows Server 2012 and Exchange 2013 on my local domain. Ive got the mailboxes setup and can send/receive emails fine when using OWA. If i try to open the mailbox using Outlook 2010, I get the below error If i try to expand the folder, i get the same message but am still able to use OWA. When I try to run a send/receive, I get the below error: After a bit of researching on the web, people suggest that the profile is corrupt. I have recreated the profile and tried again but still same error. Another post has suggested that the issue is DNS and client PCs should be able to resolve autodiscover.domain.local and server.domain.local to the IP of the server. This is fine on my network. Every user has got the same issue and I am struggling to identify what is causing the fault. Advise appreciated.

• Safe to use high port numbers? (re: obscuring web services)

  - by sofakng

  I have a small home network and I'm trying to balance the need for security versus convenience. The safest way to secure internal web servers is to only connect using VPNs but this seems overkill to protect a DVRs remote web interface (for example). As a compromise, would it be better to use very large ports numbers? (eg. five digits up to 65531) I've read that port scanners typically only scan the first 10,000 ports so using very high port numbers is a bit more secure. Is this true? Are there better ways to protect web servers? (ie. web guis for applications)

• Why does my flash video get stuck? (not lag?)

  - by Sk606

  After moving to Ubuntu 10.10 Netbook Edition, I've noticed a strange problem that manifests itself most obviously with streaming videos like youtube and hulu. The video will load and begin playing fine and eventually stop, as though it is buffering. However, it usually happens between 40 and 60 seconds into the clip. The loading indication however shows that it actually isn't buffering anymore of the data, and will just sit there. If I force the clip forward (e.g. click to start the movie somewhere ahead of the stall point) the clip will usually reload quickly and begin playing as expected. Because of the quick load times, and the consistent stop of video, I don't think the problem is related to hardware performance or network throughput. Also, I have none of these problems in 10.04. Rebooting into 10.04 makes the problem disappear. However, one more clue, I also have noticed a higher occurrence of web pages that simply "stop loading" - say, 1/10 clicks while browsing I have to hit "reload" to get the page to load because the page timed out part of the way through. This seems strangely related to the video problem, though is a lot less infuriating. Help! Where do I begin to look with a problem like this?

• Issues connecting VMWare VM to Windows 7 (host)

  - by MasterGberry

  I am on windows 7 trying to figure out why i cannot ping my computer or my VM from the other one, yet I am able to ping the router on both and other computers on the network. My desktop is running windows 7 64 bit and my vm is running CentOS 64 bit (which is what I use to test my web server stuff). At my school the VM has a dedicated IP and i don't have this issue, but I am home now and having issues trying to set this up behind my dumb router...I had already tried changing the VINC (i believe) to hide the vmnet1 and vmnet8 connections from the windows firewall and this seemed to have worked for like 5 minutes and then stopped... Any ideas? Thanks

• Can't set up printer

  - by Jason Swett

  I'm trying to set up an HP OFficejet Pro 8500 A909a on my Windows XP machine over the network. I know the IP address of the printer but it's unclear to me how to set it up based on that. I have no idea how to troubleshoot this problem. I've tried installing the drivers but when I do that it tells me the printer is on a different gateway from my workstation, which is not true. Also, other people in the office are able to connect to this printer just fine, although the driver apparently didn't work for them, either.

  So I've remotely created my first headless using ssh. Now I'm attempting to connect to this VM using RDP so I can install Ubuntu Server, but I cannot get connected at all. When starting the VM everything appears fine: $ vboxheadless -s WebTesting Oracle VM VirtualBox Headless Interface 4.0.16 (C) 2008-2012 Oracle Corporation All rights reserved.

• Is there a way to get a shared spreadsheet to update without closing and reopening?

  - by Mike

  Using Excel 2010, I have a spreadsheet that is used by 3 different people at any one time. But if one person has the spreadsheet open on there PC the other people can only view it as read only. I have since shared the workbook and put the spreadsheet on a shared network drive and now they can all view the spreadsheet at the same time and edit it at the same time. The problem is that nobody can see the changes that the other users have made unless the close out of the spreadsheet and open it up again to view the changes. I have checked the settings of the shared workbook and on the advanced tab have tick the option that updates the information every 5 minutes but the information does not update until you close out and open the spreadsheet back up again. How can I fix this problem?

• Group policy reset upon restart?

  - by sc_ray

  Is it possible for a group policy to revert back to its original state upon server restart? Our servers are hosted as a Virtual Machine on the rack. We had to restart our server for some reason and all of a sudden we cannot remote desktop into the server any more. Pinging the server succeeds but RDPing into it fails. My assumption is that the group policy has reverted back preventing any remote desktop connections from taking place. Is that a possibility? Since the network is managed by another group, we don't have the authority to physically look into what's going on with this particular VM. Can somebody suggest some ideas? Thanks

• vmconvert exchange 2007

  - by user72950

  Has anyone tried to run vmconvert on a Windows 2008 64 bit server running Exchange 2007? Here is what I did. I stopped the Exchange processes and IIS and ran vmconvert. When I moved the new server to my vmware server 2.0 for windows and booted it. All seemed well except I could not send or receive email. All outbound was stuck in the queues. I was able to log in via OWA so that tells the network setup/NIC bindings were OK. Any ideas?

• Nginx as a reverse proxy + Apache or completely cut out Apache? (WordPress Multisite)

  - by user715564

  I am starting a WordPress multisite network with domain mapping and I am trying to think through my server set up. Right now, I only have one medium sized VPS but hopefully I will need to add more servers later so ideally the solution will also accommodate future growth. My question is, would it be better to set up Nginx as a reverse proxy with Apache or use only Nginx? It seems like setting up Nginx as a reverse proxy would be easier and offer less of a possibility of problems but, on the other hand, would using only Nginx add substantial benefits?

• Is there a way to customize items on the right side of start menu in Windows 7?

  - by Basara

  OK I know I can right click on it and select properties... But it only allows me to decide whether an item is shown or hidden. What I want is, adjust item position on the start menu right side. More specifically, I want to put the item "games" in the same group where personal folders are. It makes perfectly no sense to put "games" with "computer" and "network" in same group. Or is there a registry tweak can make this possible? Thanks.

• Can I run Win7 virtualized for my HTPC?

  - by Daniel Schaffer

  I'm currently running Vista for my HTPC, and am planning on upgrading to Win7 soon. However, I've been considering installing it as a VM so that I can run Windows Server 2008 and/or Windows Home Server. The single requirement is that the HTPC must boot up to Windows Media Center with absolutely no user intervention. I need to be able to hit the power button have it go. I've got this working currently, so I don't need to keep a keyboard or mouse plugged in - all I use is my remote. If possible, I'd love to be able to do these other things: Use Win2k8 Server as a VM host for Win7 Pro and WHS. This also lets me run IIS7 for doing ASP.NET development Use WHS for all the wonderful things it does for a home network Are either of the two optional things possible while meeting the WMC requirement?

• Web map services displaying poorly

  - by user29261

  Web map services no longer display correctly in ArcGIS and Google Earth - no one else on network is experiencing these. Using windows 7 OS. These problem began abruptly (1 day they were working, the next they were not). Specific problems include not displaying at all; correct display on 10% of the monitor and repeating lines of coloured squiggles and text on the remaining 90%; and small, widely spaced, pixels in place of colour fill. Links where this occurs: arcgis http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en Google earth http://openmaps.gov.bc.ca/kml/BCGov_Web_Map_Library.kml I can't pinpoint any changes to the computer setup which may have prompted this, however, adding arcgis 10.1 SP 1 occured around the same time. Probably just a coincidence. Anyone had similar problems? or solutions to these? Thanks for any thoughts. Jim

• What constitutes "commercial purposes"?

  - by RoboShop

  I'm looking at this license. It says that I can use it for "non-commercial purposes". What does that mean? I see in Stack Exchange, under Network Profile there is that graph that tracks your points across your Stack Exchange accounts. It uses a control called HighCharts which have a paid and Creative Commons licensed version. So would Stack Overflow constitute a commercial site? We don't pay to use this site, but obviously the site makes money from ads, etc. Then again, there's a lot of sites that have ads who won't necessarily make a profit, it may only be subsiding their costs. But even then, you could argue that even if it is only subsiding their costs, a lot of IT companies run at a loss in order to build a big enough customer base. So where is the line here? Is it any website on the internet? Is it any website that has ads? Is it any website that turns over a profit?
