  • Subdocument in Word won't save

    - by ChrisW
    Because I know Word has a history of not liking very large documents (my supervisor specifically told me not to use LaTeX... grr), I decided to learn the Master document / subdocument feature of Word when writing my PhD thesis. I have the title page / table of contents etc in the master document, and each chapter as a separate document. However, when I save the master document, it appears to save all the chapter documents apart from one (Chapter 4), for which it brings up the Save Document dialog box, helpfully with "Chapter4.docx" in the "Save as" box (n.b. Chpater4.dox is not open). Clicking save does nothing, and doesn't make the dialog box go away. Saving as a different document means that my changes aren't reflected in the same document. There must be some reason Word doesn't like this particular document but I've got no idea why - there's nothing special in it that isn't in any of the other chapters. I have tried closing all documents, renaming Chapter4.docx, opening the master document, expanding all documents, OKing the warning that Chapter4.dox does not exist, and inserting the 'new' document, but even when I save the master document it still won't save the new Chapter4 document. If anyone knows any reason why Word is acting like this (or if I'm doing anything stupid), I'll be eternally grateful (p.s. sorry for the long rambling message. It's late; I've been working on my PhD 4.5 years, I really really want to throw this computer out the window, and I hope people are kind enough not to downvote this question because of it's rambling nature!) Update With Word closed, I've tried to delete Chapter4.docx (having made a backup!) - but I get a warning that it can't be deleted because it's open in Microsoft Word... these files are on a network drive and the same problems are happening on 2 different computers. I could login to the filestore through ssh and force the file to be deleted, but I'm curious to know why this is happening!

  • DNS Issue- Nameserver Issue

    - by Master-Man
    I setup new server on centos 5.3 and configure dns and hostnam using WHM. I also register my new nameservers with my domain registrar with ns1.example.com and ns2.example.com. But i am unable to ping hostname and NS. ping pc2.example.com or ping ns1.example.com I received the below email from server. IMPORTANT: Do not ignore this email. Your hostname (pc2.example.com) could not be resolved to an IP address. This means that /etc/hosts is not set up correctly, and/or there is no dns entry for pc2.example.com. Please be sure that the contents of /etc/hosts are configured correctly, and also that there is a correct 'A' entry for the domain in the zone file. Some or all of these problems can be caused by /etc/resolv.conf being setup incorrectly. Please check that file if you believe everything else is correct. You may be able to automatically correct this problem by using the 'Add an A entry for your hostname' option under 'Dns Functions' in your Web Host Manager. When I issue the command root@pc[~]# host pc2.example.com I receive the below error that Host pc2.example.com not found: 3(NXDOMAIN) I added A entries for hostname and Nameservers but nothing replies. Its almost more than 72 hours for setting & registering nameservers and dns configurations. thanks,

  • Difference between CurrentClockSpeed and MaxClockSpeed

    - by Ben
    Rationale this belongs on ServerFault rather than StackOverflow - I already have my program which gets the value, I am querying the value returned and what it means. I have an in-house program which audits our company PCs, and one of the things it checks is the speed of the processor. To do this, it queries the Win32_Processor WMI class and gets the value of CurrentClockSpeed. We were playing with the data today and found an anomaly with some of the speeds being reported incorrectly (for example, CurrentClockSpeed said 1.0GHz, whereas the CPU name said Intel(R) Core(TM)2 CPU T5600 @ 1.83GHz [Confirmed it is in fact 1.83GHz]). I did a bit of digging on the internet and found this blog post which might explain what is going on. My initial thought was that I could change the program to instead get the value for MaxClockSpeed instead of CurrentClockSpeed, but Microsoft's documentation doesn't clearly define what this will return. What I mean by that is will this return a value which is its actual maximum speed (say if it were overclocked) but which it would not normally be running at, or would it return what I expect, which is its maximum speed under normal (not overclocked) conditions?

  • Work from home on an iPad?

    - by Alex Basson
    The situation: My wife has a 13" MacBook Pro that she uses for email, Facebook, web surfing, and working from home. I'm about to buy us our first iPad. My wife's brother's computer just went belly-up, and she's contemplating giving him her MacBook and just using the iPad. The question is whether or not this is possible or realistic. Obviously, the iPad is well-suited for the email/web/Facebook tasks, but the working-from-home thing is an absolute must -- if the iPad can't handle that, it's a deal-breaker. For my wife, working from home means two things: Accessing her workplace computer's Windows Vista desktop, which she currently does via Remote Desktop. Editing Office documents locally, which she currently syncs via Dropbox. Being able to edit documents locally is important, because sometimes she will download documents and edit them when she doesn't have network access (e.g. on the subway). I'm more than happy to get a keyboard dock for her, so typing won't be an issue. Are there any iPad apps she can use to access her work computer and edit her work files? Thanks for any suggestions!

  • Setting up squid proxy server to in turn connect using another proxy server [closed]

    - by AnkurVj
    My institute uses the Squid proxy server and authentication mechanism requires username and password to be entered. This means that, I can log in on only one machine at a time and Internet access for me is restricted to that machine. I sometimes require Internet access on multiple machines simultaneously. What previosuly worked for me was the following : On one of my own machines A, I set up a Squid proxy server that allowed all local machines without any username and password. I configured rest of the machines to use this machine A as the proxy server. On machine A I logged into the institute proxy server using my browser. This way, I could access Internet from all my machines, by effectively channeling my requests through the server A. Recently, I lost that machine and configuration and now I tried to set it up again in the same manner. However, I cant seem to remember exactly how I made it work. I keep getting Connection Refused (111) on other machines. My guess is that my squid server isnt able to forward requests from other machines to the actual squid server. I could use any help for debugging this problem. I don't want to use alternatives such as ssh tunneling. This solution has worked for me in the past, I just don't remember how to set it up the same way again.

  • Windows 7 on a 64-bit computer

    - by GetFree
    I read on Wikipedia that Windows 7 on a 64-bit PC needs twice as much RAM as on a 32-bit PC. I understand why is that: every number stored in memory takes 8 bytes rather than just 4. That, in simple terms, means that your amount of RAM is reduced to half when you use Windows 7 on a 64-bit computer. Now, I have a Intel Core 2 Duo Laptop with Windows Vista right now (2 GB of RAM). My question is: Since Core 2 is a 64-bit architecture, if I upgrade to Windows 7 will my laptop be working as if it had just 1 GB of RAM? Or... to say it in other words: Having a 64-bit PC with Windows 7 do you need twice as much RAM as you need on a 32-bit PC to have the same performance? If I am right, then I'd say it's a terrible business to have a 64-bit computer and Windows 7 on it (I hope I am mistaken, though). Follow-up: After some answers, I'm realizing it's not the same thing to have a 32-bit OS on a 64-bit PC than a 64-bit OS on a 64-bit PC. Apparently, the problem of Windows 7 requiring twice as much RAM on 64-bit architectures is when you have both the OS and PC supporting 64 bits. I'd like new answers to address this issue. Also, is it possible to have more that 4 GB of RAM on a 64-bit PC using a 32-bit version of Windows?

  • Need a recommendation for shared storage on auto-scaling ec2 w/ scalr

    - by john h.
    I have come across so many answers to this question that I am completely lost! I am moving our 2 sites to a load balanced ec2 system with scalr as our cloud manager. Now the question is coming up about persistent storage for the user's uploaded content and other files. Could someone please give me a suggestion and possible a link to a tutorial for the following setup and goals. 2 websites (1 Forum, 1 ecommerce). 1 LB 1 App server (to scale out to as many as needed) 1 DB server (to scale out to as many as needed) Our sites will need to autoscale and according to what I am learning about scalr, that means as new instances load up, I need to run a script to set the basics up on that server (git,php mods, pull site from git, move keys, etc) What I don't understand is how should I handle user uploaded content like profile pictures, avatars, product images, themes, etc... Do I mount an EBS or s3fs folder to hold the websites (maybe /var/www/websitefolder) or do I do something like mount the avatar folders /var/www/websitefolder/images/avatars) I am not sure where to go with this. Could someone give me some detailed help? -John

  • Is there a better way to do bonded vlan tagged interfaces with XEN

    - by AJ01
    We have a number of XEN servers all running CentOS or RHEL. The VM's that they run are all required to be on their own VLAN for no other reason than the customer expects them to be. Long story short however, I can't change this right now. We are also required to have bonding enabled on the interfaces. So to accommodat this we enslave eth1 and eth2 to bond0. We then create a seperate interface called bond0.VLANID where VLANID corresponds to the correct vlan; eg ifcfg-bond0.204 DEVICE=bond0.204 BOOTPROTO=static ONBOOT=yes VLAN=yes BRIDGE=xenvlan204 Bridge to XEN As you will see, we eventually have to bridge this out to XEN, and we do this by adding another interface called xenvlan204 (in this instance) which contains; ifcfg-xenvlan204 DEVICE=xenvlan204 BOOTPROTO=none ONBOOT=yes TYPE=bridge XEN Vm Config Finally in our XEN config for each VM, we add vif = [ "bridge=xenvlan204" ] This then allows the vm host to access that particular vlan The Problem We've noticed a few problems with this setup. One being that we currently create the interfaces manually. Which means if we add more vlan enabled interfaces and bridges we usually have to restart xend which is something I'm not so hot about. Also lower level staff have their heads melted by the number of interfaces and the risk of a mistake occurring is high. Secondly, it can take sometime for a host to come up if it has a number of vlan taged interfaces. Thirdly, its just not scaling well on the management aspects The Question Is there a better more flexible way to do this (in particular with Xen that ships with centos 5.3, 5.4 and 5.5 as we have to support all three) that leverages either scripting or other solutions to allow an arbitrary amount of interfaces to be created when a vm is instanced. Your advise and expertise is more that welcomed.

  • CLOSE_WAIT sockets burst - perhaps because of iptables settings?

    - by Fabrizio Giudici
    I have an Ubuntu 12.04 server virtual box where basically the installed software and configuration are the default ones, plus the installation of a jetty 6 server which servers a few websites. To keep things simple I didn't install apache httpd and used iptables for exposing jetty (which runs on the 8080 port) to the port 80. These are the results of /sbin/iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere localhost tcp dpt:http redir ports 8080 REDIRECT tcp -- anywhere Ubuntu-1104-natty-64-minimal tcp dpt:http redir ports 8080 Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere localhost tcp dpt:http redir ports 8080 REDIRECT tcp -- anywhere Ubuntu-1104-natty-64-minimal tcp dpt:http redir ports 8080 Chain POSTROUTING (policy ACCEPT) target prot opt source destination I must confess I have a shallow comprehension of how iptables works, in particular for the different kind of chains. This thing works, but sometimes I have an explosion of sockets that stay permanently in CLOSE_WAIT state. I know about what this state means, but since I didn't write the code that manages servlets (they are handled by jetty) I can't fix the problem by patching my code. Eventually the amount of CLOSE_WAIT sockets builds up and makes the server not responsive, so I have to restart jetty. I've looked around for similar problems wth CLOSE_WAIT, and only found cases related to the programmer's code, or problems with Tomcat, not Jetty. I was wondering whether they could be related to a partially broken iptables configuration (the alternative is a bug in Jetty 6, but I first want to exclude other possible causes). Thanks.

  • DDoS nulling to some ips and other options?

    - by Prix
    I am looking for some information in regards DDoS in the follow scenario: I have a server that is behind a Cisco Guard and it will be DDoS'ed, I only care about a set list of IPS that by not means are the attackers. Is it possible to null all other ips but this list to actually get any response to my server or in the long run no matter what I do if they have enough DDoS power I will just go down like a flie ? Is there any recommended company out there that can actually cope with a DDoS ? My server will mainly run several clients that will get connected to a external server and all it needs access to is my local MySQL the the private network so I can access it. There will be no other services runnings such as web or ftp etc at least not to the external ips of the server if i ever have to have any of these service they will be on the private network. The MySQL will be available externally only to 1 safe ip not known by anyone but me and internally at localhost + private network. Are there any solutions ?

  • Is there a screen sharing/remote desktop app for mac that lets you use a different host screen resolution?

    - by MarqueIV
    Ok, there are tons and tons of questions about remote desktop for mac and they're all being closed as duplicates. I however am specifically looking for one that will let me use a different resolution than the host, the way you can with Remote Desktop for Windows. For instance, when I connect to my 11" Macbook Air booted into Windows7 from my quad-screen desktop, also booted into Win7 using Microsoft's Remote Desktop Client, it blanks out the screen on the notebook, then virtualizes the video across all four of my desktop's monitors at their native resolutions (2560x1600, 2 x 1920x1200 and 1600x1200) and the notebook now acts as if it has four physical monitors connected to it. All of this from a notebook that only has a 1366 x 768 native resolution. Even when running OS X on the client running RDC, while it doesn't support multi-monitors like its Win counterpart, it still lets me run at the native resolution of the client screen of 2560x1600. Again, it just blanks out the host screen while doing so. However when using Mac's screen sharing, since that is just glorified VNC, it just mirrors what's already on the host's screen, meaning it will always be a single screen with the resolution of 1366x768. This of course makes sense since VNC is a mirroring solution, not a video-virtualizing one like RDC, but it means that on my quad-monitor setup, the remote window isn't even large enough to fill up a single monitor, let alone four (unless you have a client that can scale it up, but that's video scaling. It's still only 1366x768.) So what I'm looking for is if there is a solution on the Mac that lets me do the same thing as RDC in a Win environment. Don't care if I have to pay. I'd gladly pay several hundred dollars for this. I just need that specific feature. Note: People have suggested various VNC clients, but the VNC host still runs at 1366x768 so that will not work here. Ever. Also, people have suggested Synergy/Synergy+/Teleport and such which share the keyboard and mouse, not video. Completely different animal unrelated to what I'm looking for.

  • How do I remove encryption from a VMware Workstation 7 image?

    - by Chad
    I successfully encrypted a VM image and confirmed it still runs. I then closed the VM and reopened it and confirmed the encryption password was valid and worked. However, now I want to un-encrypt the VM. When I choose that option, it asks for "your password". I assume this means the password I created when I encrypted it. It doesn't work. I can still open the VM with the password and run it. But, it refuses to remove the encryption using that password. Am I missing something? Is there a password that I don't know about? Some details: I created this image (using standalone converter; physical machine source) I converted it to ACE Converted back to a normal VM (un-ACE'd it) Encrypted it Cannot remove the encryption but can open it and run it As you can see... I am exploring the VMware features. Thanks for any guidance you can give.

  • Define custom escape sequences in terminal

    - by Ipkiss
    I would like to change the escape sequences used by some keys in my terminal. My goal is to define custom mappings in Vim (terminal version). In the following I use shift-space as an example, but I would prefer if the proposed solution could be generic. My current terminal (gnome-terminal) uses a simple space as escape sequence for shift-space, as can be seen by typing ctrl-v shift-space. A quick check with the true xterm shows the same behavior. I would like that the shift-space key combo generates another escape sequence (e.g., the one of shift-F30, which I would never use otherwise). So, how would I go about doing that? And is it really a good idea? Let me know if there are better alternatives... Note: I'm aware that this is only part of the problem: after the terminal sends a proper escape sequence for my keys, I still need to teach Vim what it means. But I think I know how to deal with that.

  • How to share text, pictures and video to restricted set of users

    - by joaoc
    I want to share pictures and videos of my kid growing up but I don't want it to be open to the public. I just want me and my wife to be able to add material and then share with grandparents and friends who would be given a username/password or some other solution that authenticates them. This content would preferably be available remotely over the internet or downloaded periodically to the allowed viewers computers. The second option most likely means they would have to install a client, which I am not too fond of doing (I would have to ask them to install it, help configure for different platforms, ...) I'm at the start but I would like software that also allows export of the data (if one day I want to migrate to a different solution). Folder sharing I don't know if Windows folder sharing is reliable, robust and safe enough to share over the internet. Dropbox could be a software solution, but it's limited to 2GB and requires receivers to also install and configure software. A folder is just a collection of files, so it would be harder to keep them organized with text describing the pictures/video Email I could email the content every now and then but videos are almost always too big to go as attachments This would also not provide a history of updates to anyone just recently joining in Are there other solutions to achieve this? NOTE: I also thought that software to run a local or remote blog could be an option but we aren't allowed to ask those questions on superuser because one admin doesn't like cloud-computing questions. But if you do think it's the best approach and can suggest a solution, do state it in the answers anyway!

  • Flow of packet in network

    - by user58859
    I can't visualize in my mind the network traffic flow. eg. If there are 15 pc's in a LAN. When packet goes from router to local LAN, do it passes all the computers? Means did it goes to ehernet card of every computer and those computers accept the packet based on their physical address. To which pc the packet will go first? To the nearest to the router? What happen if that first pc captures that packet(though it is not for it)? What happens when a pc broadcast a message? Do it have to generate 14 packets for all the pc's or only one packet reach to all pc's? If it is one packet and captured by first pc, how other pc's can get that? I can't imagine how this traffic is exactly flows? May be my analogy is completely wrong. Can anybody explain me this? Thanks in advance.

  • Isolating a computer in the network

    - by Karma Soone
    I've got a small network and want to isolate one of the computers from the whole network. My Network: <----> Trusted PC 1 ADSL Router --> Netgear dg834g <----> Trusted PC 2 <----> Untrusted PC I want to isolate this untrusted PC in the network. That means the network should be secure against : * ARP Poisoning * Sniffing * Untrusted PC should not see / reach any other computers within the network but can go out the internet. Static DHCP and switch usage solves the problem of sniffing/ARP poisoning. I can enable IPSec between computers but the real problem is sniffing the traffic between the router and one of the trusted computers. Against getting a new IP address (second IP address from the same computer) I need a firewall with port security (I think) or I don't think my ADSL router supports that. To summarise I'm looking for a hardware firewall/router which can isolate one port from the rest of the network. Could you recommend such a hardware or can I easily accomplish that with my current network?

  • What is the difference between these Pentium Extreme Edition CPUs?

    - by Giffyguy
    The CPU in question is the Pentium Extreme Edition 955. Intel's website shows four "versions", but for the most part they all look identical. They even share the same set of ordering codes. But one of them has a substantially lower TDP, which is seemingly unexplainable - since everything else is the same. Two of them say "LGA775, Tray" and I have no idea what "Tray" means either. Also, two of them have a different SPEC code. What I need to know is: What does "LGA775, Tray" mean? Why does the one CPU have a lower TDP? And what does that mean for me? Does that mean lower maximum power consumption? Does it mean the CPU may be more stable/endurant, because of a lower heat output? Why do two of them have a different SPEC code, and what does this mean? Finally, what does PLGA775 (as opposed to LGA775) mean, and do I need to be worried about that?

  • How to encourage Windows administrators to pick up scripting

    - by icelava
    When i worked as an administrator in my first job, I was frustrated our administration processes with Windows servers were a series of point-and-clicks; we could never match the level of efficiency with the Unix servers which had a group of shell scripts to automate a lot of the work. I soon read about WSH and ADSI and wasted no time learning just how much automation I was able to achieve with scripting. There was a huge problem though - almost none of my Windows colleagues were really interested in learning scripting. They seemed happy with the manually mouse-clicking chores and were never excited at the prospect of using scripts to do the work on their behalf. I struggled to convince them to pick up scripting skills despite the evident increases in efficiency. I left that job in pursuit of a full-time software development career thereafter. Almost a decade on working in various environments and different customers, I still encounter Windows administrators mainly possessing this general "mood" where they would avoid scripting as much as possible. Despite the increasing level of accessibility Windows server technologies are opening up for scripting and automation. I am almost certain the majority of administrators are administrators precisely because they absolutely hate performing any kind of programming duties. What are some means to encourage and motivate administrators that scripting can really help them in the long run?

  • Standards for documenting/designing infrastructure

    - by Paul
    We have a moderately complex solution for which we need to construct a production environment. There are around a dozen components (and here I'm using a definition of "component" which means "can fail independently of other components" - e.g. an Apache server, a Weblogic web app, an ftp server, an ejabberd server, etc). There are a number of weblogic web apps - and one thing we need to decide is how many weblogic containers to run these web apps in. The system needs to be highly available, and communications in and out of the system are typically secured by SSL Our datacentre team will handle things like VLAN design, racking, server specification and build. So the kinds of decisions we still need to make are: How to map components to physical servers (and weblogic containers) Identify all communication paths, ensure all are either resilient or there's an "upstream" comms path that is resilient, and failover of that depends on all single-points of failure "downstream". Decide where to terminate SSL (on load balancers, or on Apache servers, for instance). My question isn't really about how to make the decisions, but whether there are any standards for documenting (especially in diagrams) the design questions and the design decisions. It seems odd, for instance, that Visio doesn't have a template for something like this - it has templates for more physical layout, and for more logical /software architecture diagrams. So right now I'm using a basic Visio diagram to represent each component, the commms between them with plans to augment this with hostnames, ports, whether each comms link is resilient etc, etc. This all feels like something that must been done many times before. Are there standards for documenting this?

  • Using VMware Guest OS to enable Host OS to ssh to remote network

    - by Reuben L.
    Basically I have an issue because my host OS is 64-bit Linux Mint (Ubuntu derived) and it doesn't seem to be compatible with the Juniper Network Connect that is used by the network at my workplace. Thus, I am unable to ssh from terminal to the network. I can't make changes to the workplace network either so that leaves me with looking for solutions on my end. The main reason for me to access the network from home is to check on my running processes or to issue more commands to a few workstations. Putty is the desperate choice I usually make but it means I have to reboot to Windows and also have limited control. I've tried several other methods and they have all failed. Recently, I setup a VM with Windows 7 as the guest OS. Now half my problems are fixed as I don't have to physically reboot the system - I just have to engage Juniper Network Connect on the VM. However, I would still like to use my Linux terminal to ssh to the network. It sounds plausible that I could somehow manipulate ports to connect to the remote network from the host OS tunneled through the guest OS, but I really have no clue how to do so... Can anyone help?

  • OS X can connect to Windows machine, but can't access shared folders

    I can create new folders on my Windows XP machine, set them to "shared". On my Mac, I pick Finder → Go → Connect to Server → smb://192.168.1.4 → Connect → Name / Password. It even shows me all the names of the newly created shared-folders on my PC, but when I try to actually connect to any of them I get connection failed, there was an error connecting Any idea on what would cause that? The fact that it successfully gets so far—to actually showing me my PC share-names—must mean I have 99% of this working correctly, i.e. the physical connection, the IP address, the user name, the password, etc. Still, I can't seem to access the folders themselves. I've tried this with my Windows XP firewall on/off, and Norton AntiVirus on/off. Same problem. Everything did work fine, 4 months ago. Were there any odd OS X or Windows updates released recently? I always apply them all. smbclient on the Mac does correctly find the XP machine, my XP user name, and accepts my XP password. I get the following from that smbclient command: Doing spnego session setup (blob length=16) server didn't supply a full spnego negprot Got challenge flags: ... Got NTLMSSP flags: ... Got NTLMSP flags: ... Domain=[XPMACHINE] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager] tree connect failed: NT_STATUS_INSUFF_SERVER_RESOURCES I'm not sure why a standard XP box can't "supply a full spnego negprot". Whatever that means. Using XP's RegEdit to change my IRPStackSize from 11... to 13, 15, 20, 22... still gives that "NT_STATUS_INSUFF_SERVER_RESOURCES" error on the Mac.

  • Partitioning & Linux

    - by Zac
    Every tutorial on Linux-based partitioning schemes (or, just partitioning in general) will tell you that a PC can have either 4 primary partitions, or 3 primaries and 1 extended. They will all also tell you that Linux (in my case, Ubuntu) can be installed on either. It's also come to my attention that it is not too atypical for FHS directories, such as usr/, tmp/, etc/, home/ or var/ to be mounted separately on other partitions. Several questions I am unable to find the answers to, purely for my own edification: (1) By "PC", are we really talking about common PC disk types, like IDE or SATA? I guess I'm wondering why PC uses are limited to 4 primaries or 3 primaries + 1 extended (2) I'm choking on some basic OS concepts: it is said that a partition can be mounted by a file system or an OS. So I assume this means I can somehow instruct Ubuntu to mount to 1 partition, and then any part of, say, ReiserFS, to be mounted to another partition? How? (3)(a) What about creating swap partitions? Is there too much of a good thing with swap partitioning? If I have 4GB RAM over 320GB disk, what should my swap partition size be, and why? (3)(b) Are swap files the only way to create swap partitions? Wouldn't a Linux partitioning utility allow me to define a partition as being for virtual memory only? (4) Why are partitions limited to being "mounted" by just OSes and file systems? Why couldn't I write a program to take up its own, say, 512 MB partition, and then have it invoked or uses by an OS installed on another partition? Thanks for shedding any light here... not critical that I know this stuff, but it's got me thinking incessantly. And when I think incessantly, I...can't......sleep....

  • openvpn problem

    - by Jared Voronik
    I have a problem with openvpn. I have already setup openvpn sucessfully on some other servers in the past (basic configuration, nothing special). On this server, I used the same config file, but for setting up nat iptables -t nat -A POSTROUTING -s 10.4.0.0/24 -o eth0 -j MASQUERADE doesn't work. It gives error: iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. How do I fix this error? Also, if I can't fix this error, can I do bridging instead of routing? I have only 1 interface, and I can connect to remote server only via ssh (and need to avoid reboots if at all possible) so if briding means a whole ethernet card has to be devoted to the openvpn (and no other servers) then briding is out, otherwise I can use briding. Do you know of a simple, step by step guide to configure openvpn briding (just simple openvpn server and clients that can access internet through vpn server, nothing fancy)?

  • Upgrade SQLServer 2008 hardware

    - by John
    Forgive me if I'm not able to be totally clear here. It is not intentional, I'm a senior level developer in a very small company having to act like a manager at the moment. Anyway, the story is that we have 2 older dell servers with SQL Server 2008 Standard in a "cluster". I put that in quotes because I'm still not 100% clear what that means. We have 2 brand new blade servers and want to move the existing databases to the new hardware. Ok, so here is the gotcha. We need to do this with little or no down time. I'm being told that we can evict the passive node, then pull in one of the new servers. But I'm also being told that this is a dangerous step because something could go wrong that would cause the cluster to fail and then we would be left with nothing because the active server would not be able to come back up. Does anyone have any thoughts on how to handle this? I'm being told that the only way to ensure success is to have at least a day of down time where we bring up a new cluster on the new hardware and then migrate the databases 1 by 1.
