  • Setting up Multiple Routers (as Hardware Firewalls) behind a Home Router

    - by Synetech
    I’ve currently got one computer behind a router with built-in firewall functionality, connected to a home cable-modem that has a single Ethernet port and one IP. I’m going to have to set up another computer for the rest of the family to use which of course will need to be connected to the Internet, probably wirelessly since the modem is in my room and the new system would not be. What I would like to do is to get two more small routers with firewall capability and connect each computer to a router, which would in turn connect to the main router which connects to the cable-modem. That way, both systems have a hardware firewall protecting them (particularly the wireless system) and the burden of blocking would be reduced on both the computer CPUs and the main router because the secondary routers would handle some of the workload. I’m trying to find out about the complexities inherent in this design and how I could set it up to work, specifically the IP handling and NAT aspect. Thanks a lot.

  • Remote Access Without Explicit Permission: Convenience or Liability?

    - by routeNpingme
    For outsourced professional IT remote support, one habit most new technicians get into is the "instead of getting the user to start up remote support each time, I'll go ahead and install LogMeIn / GoToMyPC / Remote Desktop / whatever so that if they call again, I can just jump on and help them". This of course opens up a potential liability because a client PC on a network that we don't own is being accessed without a user explicitly providing permission by clicking a "Yes, allow technician to control my PC" option. I realize the rules totally change when you're an IT admin over a network that you "own", but this is outsourced IT support. Just curious what others' policies are. Is this an acceptable practice for convenience and I'm turning into one of those "security is more important than anything" people, or is this really a liability?

  • HTTP resource caching / fetching

    - by Bobby Jack
    I'm trying to optimise a page, and I'm seeing some strange behaviour. Each time I click on a link to the page, all resources are fetched from the server, responding with 200s. However, when I refresh the page (specifically, F5 in Firefox), all resources return a 304 and - of course - the page loads much faster as a result. The main page returns a 200 in both cases. In the refresh case, If-Modified-Since headers are sent with the requests to the resources. However, in the 'clicking a link' case, they are not. What's the reason for that, and can I control it?

  • Control scheduled tasks execution

    - by SJuan76
    We are a small shop. I am mainly a programmer, but due to being the only one that risks to manage our servers, the task has fallen on me (yet I it is still a secondary function so I cannot give it too much time). Over the course of years we have needed to create a decent number of .bat scripts that run as scheduled tasks in our servers (dump DB servers, SVN servers, copy files, etc.). Manually checking that everyone has proceeded ok is a time consuming task. I could get them to send an email on completion, but then I would get swarmed by lots of emails each morning. If I setup them to only e-mail on failure, I might miss the instances where the error causes the task to abort (or even not to start). Are there other alternatives? We are currently using Windows 2003 R2, but we are thinking of adding some Linux server soon, so a cross-platform solution would be best.

  • Trouble with resolving hostnames on CentOS using Bind

    - by cabaret
    I'm taking a course on server administration at school and I have managed to set up virtual hosting in apache and a dns server on a virtual machine. However, I have now set up an old pc to run CentOS and I'm trying the same on that box. The problem I ran into now is that I can't resolve hostnames from the linux box. I have set up the nameserver in /etc/resolv.conf to the IP of the CentOS machine, but when I try for example ping google.com I get ping: unknown host google.com However, when I do ping 66.102.13.105 (which is the Google IP, figured that out by pinging on my mac) I get: PING 66.102.13.105 (66.102.13.105) 56(84) bytes of data. 64 bytes from 66.102.13.105: icmp_seq=1 ttl=52 time=15.5 ms Slightly confused why this is happening. Could it be because of my router sitting in between the linux machine and the cable modem? It's a D-Link somethingsomething. Thanks in advance

  • VMware - Watching multiple virtual machine screens

    - by mr.b
    Hi, I don't know even if I put the question right, but here's what I'd like to accomplish. I have avoided specifying exact Vmware virtualization product here because I'm not sure which one would be most suitable for the task at hand. I am developing an application that works in local network. This application has to run on several computers at the same time, and it's important to me, as a developer and tester, to see (literally) how it behaves at all times on all computers. Is there any way to connect to screens of virtual machines deployed on ESX, ESXi, Sever 2.0, or some other product, so that I can see something like grid of screens, say 4x4 or 6x4 or whatever number of scaled screens, at the same time? Ability to interact with screens directly from grid (by double-clicking a screen, for instance, and then getting full resolution screen) would be greatly appreciated, of course. I hope that someone understood what I meant here. :)

  • Can't edit a specific document in Word 2007

    - by Benjotron
    I have a document in Word 2007 that seems to be read only. There are forms in the document that I can type in, but I can't edit or reformat the rest of the document. There is probably a setting somewhere I can flip to make it editable again but I can't find it for the life of me. FOLLOW UP: The "Protect Document" button only had "Unrestricted Access" checked, this was one of the first things I checked. However, when I tried checking "Restrict Formatting and Editing" it brought up the Restrict Formatting and Editing sidebar, which stated: This document is protected from unintentional editing. You may only fill in forms in this region. With a stop protection button on the bottom, which of course solved the problem. I think that menu item just has a bad name, it should be "Restrict Formatting and Editing Options or Settings"

  • Best way to convert from IMAP to POP3?

    - by Brad
    At work, I connect to a corporate Exchange server via IMAP and Thunderbird 3. Over the course of a year or so, I've created quite a few folders on the server and have a lot of mail stored there. I'm hitting the storage limit of my mail account and want to convert to pulling mail down to my local box (running Linux) via POP3. I know that polling mail will only get mail in INBOX, but I'm wondering if there are solutions out there that could be used to pull mail from the other folders as well, or am I doomed to moving mail into the inbox manually and polling over and over again?

  • Why's SMC failing on startup?

    - by Brian Knoblauch
    Trying to remove a user from one of our servers, but I seem to be thwarted at every turn... SMC refuses to load the user list (failing with a NoClassDefFoundError in the listAll method of UserContent). vipw just returns with "vipw: /etc/passwd file busy". I'm the only user on the system at the moment (it's our backup SRSS box), and both of these fail even right after a reboot. I don't have console access at the moment either unfortunately (or I would try single user mode). Of course, even if init mode S worked and let me do this one task, it doesn't solve the root problem. Ideas?

  • Quake 3 won't install on Windows 7

    - by Ernest Friedman-Hill
    Today I tried to install Quake 3 from my original 1999 CD on a Windows 7 laptop. Windows 7 resolutely refused to run the installer, helpfully explaining that I might need a 32- or 64-bit version, depending on what my OS is (you have to love those Windows error messages: absolutely correct, but as unhelpful as humanly possible). In any case, of course the 1999 software is 32-bit, and the laptop is 64-bit. But I was pretty sure that 64-bit Windows versions could handle running 32-bit software. What gives?

  • Change Block Tracking settings not retained for a VM on VMWare 5.5

    - by Chris
    I'm trying to enable Change Block Tracking as per this VMWare KB article but the setting ctkEnabled is not being retained in the advanced options or being added to the vmx file. The setting scsi0:0.ctkEnabled is being retained and I see a file vmname-ctk.vmdk in the datastore. I've verified that the vm doesn't have any snapshots but don't see any other suggestions in the KB (or google, of course.) Edit: The last comment on this community post. It's a slightly different circumstance, but suggests that there is an known bug editing these settings in the web-gui.

  • Run non-interactive script in single user mode

    - by Jed Daniels
    Is it possible to run a "startup" script when booting into single user mode? I need to be able to boot into single user mode, run my script, then reboot into multiuser mode without any human interaction. I've done a bunch of research and can't find anything that is clear on the topic, although of course I could replace something else that does run with a wrapper that also launches my script, but I'd prefer to do it in some official way. Ideally, the solution will work in FreeBSD 6 and up, but I'm willing to accept only new versions if it just doesn't exist in the older revs.

  • Killing CLOSE_WAIT sockets without killing parent process on Linux

    - by Alex Neth
    Tomcat is leaving me with CLOSE_WAIT sockets which ultimately saturate the maximum number of connections. I've tried many methods in my client and server code to get rid of these to no avail, including closing connections, calling System.gc(), etc. Now I'm trying to find a way to simply time these out quickly in the OS. I've got conntrack working, but am not sure how to use that to kill these connections. I've also set /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_timeout_close_wait to 1, which of course is too low but the connections persist. Is there a way to kill these zombie sockets? Running Ubuntu.

  • When copying VM filesystem over netcat, dd copies double the disk size

    - by JivanAmara
    I'm attempting to copy the disk of a working headless virtualbox VM (VM1) on one server to a new VM (VM2) on a vCloud server. I don't have access to the host of VM2. The OS is Windows Server 2003 (32-bit) I start both VMs with a live Knoppix image. I run 'nc -l | dd of=/dev/sda bs=512' on VM2 I run 'dd if=/dev/sda bs=512 | nc ' on VM1 I previously did this with another windows VM and it worked fine. VM1 has a disk of size ~70GB (verified with fdisk); however, the amount of data dd reports read/written is ~139GB. Of course the target machine doesn't work properly. I get a Windows splash screen, then blue error screen with general 'system not working' information. I'm at a loss what could cause this. Any ideas?

  • How to update a keyboard layout DLL on Windows?

    - by user87690
    Information about keyboard layout is stored in keyboard layout DLLs on Windows. One can make a custom layout using a tool like Microsoft Keyboard Layout Creator (http://msdn.microsoft.com/en-us/goglobal/bb964665.aspx). It creates the dynamical library and also an installer which places the DLL at a right place and also puts necessary information to registry so the layout can be used. Now my question. How can one update his custom layout? One could uninstall the layout and install the new version which effectively replaces the DLL file. However this alone doesn't work because it seems that the old copy of the DLL stays loaded somewhere and is used when one sets the layout instead of loading new version. So is there a way how to tell the system that its “keyboard layout cache” is invalid? Of course I could reboot the whole system but I'd like to avoid it as it's annoying and seems to be poor design to reboot whole system just to reload a DLL.

  • I need a few minutes of dedicated server a week, but not for hosting, just to convert ogg etc

    - by talkingnews
    I'm completely happy with my webhosting, it's just that I need to do one little thing they won't allow, and that's run an instance of Sox to convert about 30 mp3s to ogg files, in various directories, a couple of times a week, to be done automatically in response to the detection of the upload of an mp3. Probably looking at a minute of server time over the whole week. I've had unhelpful suggestions on other forums like "why not leave your home PC on 24 hours a day and then use all your isp bandwidth to do this", which doesn't work for me. I know that I can host files on, say, Amazon S3, but is there something similar for my needs? All it would need to do would be: wget/ftp the mp3 files, convert them to ogg, ftp the files back to my hosting. Of course, all this wouldn't be needed if there was such a thing as a compiled binary of Sox (or any mp3ogg converter) for Centos which I could upload without needing root access, but I've given up asking that one, but always open to suggestions!

  • Block a machine from accessing the internet

    - by Simon Rigby
    After some confirmation that I have thinking right in this scenario. We have a number of wired and wireless machines which presently have direct internet access. I also have a Linux (Ubuntu) server which is used as a file server for the network. Essentially I would like to be able to turn internet access on and off for machines. My plan is to block these machines by MAC address at the router. I would then set up a proxy server on the Linux box (ie Squid) so that the machines I wish to restrict can access the internet via the proxy. As I can adjust access via ACLs in squid, I would be able to switch on or off a machines access to the internet without having to further adjust the router's MAC rules. And of course I could go further and create a few scripts to assist with this admin task. Does this seem sound and have I over looked anything? Any help greatly appreciated. Simon.

  • What is windows 8 core?

    - by Journeyman Geek
    I've found some references, when looking for information on WAIK installs of windows 8 of a varient called windows 8 core, that can be installed off the professional edition disk. There's also a mention of it on winsupersite that says The cheapest, called MSDN Operating Systems, costs $699 a year ($499 renewal), and of course includes Windows 8 (Core), Windows 8 Pro, and Windows 8 Enterprise. You get five licenses each for Windows 8 Core and Pro, and one Multiple Activation Key (MAK) for Windows 8 Enterprise. What is windows 8 core? Is it the new 'home' edition or something else? What differentiates it from the pro and enterprise editions?

  • Why is access to my database very slow?

    - by Fabien
    I have a mysql database that used to work perfectly fine, but now it is dead slow on startup. When I type in $> mysql -u foo bar I get the following usual message for about 30 seconds before I get a prompt : Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Of course, I tried it and it goes a lot faster : $> mysql -u foo bar -A But why do I have to wait so long in regular startup ? This is not a very big database, and data does not seem to be corrupted (everything looks fine after startup). I have no other client connecting to the mysql server at the same time (only one process is shown with the command show full processlist) and I have already restarted the mysqld service. What's going on ?

  • CPU and HD degradation on sourced based Linux distribution

    - by danilo2
    I was wondering for a long time if source based Linux distributions, like Gentoo or Funtoo are "destroying" your system faster than binary ones (like Fedora or Debian). I'm talking about CPU and hard drive degradation. Of course, when you're updating your system, it has to compile everything from source, so it takes longer and your CPU is used at hard conditions (it is warmer and more loaded). Such systems compile hundreds of packages weekly, so does it really matter? Does such a system degrade faster than binary based ones?

  • Serverlocation moved and how can I Move the files

    - by Bernhard
    Hello together, I´ve a big problem. I have to move data from an old Webspace which is only accessibla by ftp. No we have a new root server which is accessible by ssh of course :-) No i Need to move all data from the old space but there is a lot of Gb of files. Is there a way to fetch all files directly from the old ftp to the storage and not over a third station (my local machine)? I´ve tried it with ftp but without success. I think I´ve used the wrong commands. Is there a way to etablish something like this including all files and directorys? Thank you in advance Bernhard

  • Sync Banshee library data.

    - by Dom
    I use Banshee to organise my music, I particularly like its scoring system and I have smart playlists based on it. However, I have two versions of my music library, one on each of my computers. As one of the computers is small I only have a favourite set of songs on that computer rather than my whole collection. The computers are not on a local network, but I do use Ubuntu One for file sharing between them. Is there any way I can synchronise song data (play count, score, skip count ...) and playlist data (including smart playlists that include songs based on this data) between the two computers? This would only be relevant of course for the songs that exist on both computers, the songs that exist on only one would need to be ignored. I did consider putting the library data file (I think it is .xml but I'm not sure) into the shared file and creating a symbolic link to it, but then I wouldn't be able to have a different set of songs on each computer. Thank you.

  • How do I securely share / allow access to a drive?

    - by sleske
    To simplify backing up a laptop (Windows Vista), I'm planning on sharing its C: drive (with password protection) and using that to back it up from another computer. What are the security implications of this? If I share C: with a reasonable password, how big is the risk of compromise if the system is e.g. inadvertently used on a public WLAN or similar? Background: I'm planning to use [Areca Backup][1] to back up two systems (Windows XP and Vista). My current plan is to install Areca on the XP box, and share the Vista system's C: as a shared folder, so the XP system can read it. Then I can set up the drive as a network drive and have Areca read it like a local drive. Of course, if you can think of a more elegant way of doing this, I'm open to suggestions.

  • Best way to compare (diff) a full directory structure?

    - by Adam Matan
    Hi, What's the best way to compare directory structures? I have a backup utility which uses rsync. I want to tell the exact differences (in terms of file sizes and last-changed dates) between the source and the backup. Something like: Local file Remote file Compare /home/udi/1.txt (date)(size) /home/udi/1.txt (date)(size) EQUAL /home/udi/2.txt (date)(size) /home/udi/2.txt (date)(size) DIFFERENT Of course, the tool can be ready-made or an idea for a python script. Many thanks! Udi

  • What about IPv4 class E?

    - by Luc
    IPv4's class E network (240.0.0.0/4) contains 268 million addresses. Despite the advertisements for IPv6, claiming we have ran out of address space, this block ironically still claims to be "Reserved for future use". Why hasn't this block been freed up yet? Of course, IPv6 should be promoted instead of freeing up more IPv4 addresses, but we've seen the address shortage coming for years. There has even been a time they weren't sure there was enough time to develop IPv6 before we would run out of addresses. Why didn't they free up this block already? And is there any chance these addresses will be used in the future, like when IPv6 is fairly widely implemented but we still need IPv4 for backwards compatibility? It will be phased out regardless, but then ISPs don't have to employ NAT for IPv4 compatibility.
