• IBM Thinkpad 240 - Best way to boot from floppy to USB - Best Linux for 300 MHz 128 MB RAM 800x600 s

  - by zillion

  Mostly I still have that old 'ultraportable' laptop that is mostly like a pre-netbook era laptop and a friend and programmer needs a computer because the one he was using just broke and he has to wait until the new one arrive in 4-6 weeks ... This laptop has no LAN connection and CD-ROM so be prepared for a real challenge! All hardware is well supported on Windows XP (included drivers on the Windows XP CD) and on Linux out-of-the-box (but the screen need a special configuration.) Mostly any Linux that will work well with Skype (USB or regular headset), any MSN client and a text writer for code will do. What I have tested so far: Slitaz 2 don't boot because the floppy of GRUB4DOS don't see the USB drive (fully working and tested on my regular laptop), Damn Small Linux was working but was needing a special screen configuration that I don't remember (in the boot options of the floppy) and now I'm thinking about Puppy Linux that is seen to work totally out of the box with it but I will need an old Puppy version (1 or 2 I think) and the Wakepup floppy ... If you got some ideas to help or to try I'm open!

• PHP & IIS 6 Encoding problem

  - by Alexander

  The server is running Windows 2003 with IIS 6.0.3790.1830 x86 (iis.dll). My database server is Microsoft SQL Server 2000. My PHP version is 5.3. The original application is hosted on appserv1 and it's database is on dbserv1. It's working fine, everything is tuned up, running great. It was needed to place the same application (different modules) on another server, for other uses, so I copied the database on dbserv2, configured appserv2 to host the application, so I achieved 2 almost identical copies. Both dbserv1 and dbserv2 use the same encoding, both appserv1 and appserv2 are on IIS6 with the same PHP configurations. I also tried my best to have the same settings in the IIS. I also made sure that I pass the encoding information both in the HTTP headers and in the meta tags with http-equiv. Both applications use utf-8. The Problem is that the copy of the application doesn't display the non-ASCII characters normally in the browser, even if the browser detects correctly the UTF-8 encoding of the page. First I thought it was a database issue, given the fact that MSSQL 2000 doesn't support UTF-8, and instead it uses UCS-2, but when I redirected the application on appserv2 to work with the database on dbserv1, it had the same encoding problems. This is why I am asking in what way I can make it work. thank you for reading.

• Can't install SB750 RAID drivers in Windows 7 for two additional storage drives

  - by jf46

  Mobo: ASUS M4A79XTD, 790X/SB750 OS: Windows 7 x64 I currently have SATA 1-4 set to RAID and SATA 5-6 set to IDE. I have an SSD connected to SATA5 with Windows 7 installed on it, and that works fine. I also have configured a RAID 1 array of two 1TB HDDs, connected to SATA 1 and 2. These don't show up in Windows, and I'm having trouble getting the RAID driver installed. I even tried booting from the Windows DVD and repairing or installing Windows, but when I navigated to the relevant .sys files on my motherboard's driver CD, Windows setup told me that the files in question weren't relevant to my hardware. To be clear: I'm not trying to install Windows on a RAID. I have Windows installed on a separate disk on a separate SATA controller. I just want to get the SB750 RAID drivers installed so that the Windows disk utility can see my RAID 1 array, which is composed of two other disks. Do I need to wipe my SSD and reinstall Windows to get the RAID driver installed? That seems kind of ridiculous, and given what I described above, I'm not even sure it would work. Any help or guidance would be appreciated - thanks! Edit: Also, I've copied the driver files from the mobo CD into system32 and rebooted, no luck. Then I changed HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV\Start from 3 to 0, and that didn't work either.

• Error loading operating system: format Windows 7 to Windows XP Service Pack 3

  - by Blerta

  I saw that there are other questions like mine here. But O also saw that some problems where solved with fixmbr from a Windows 7 recovery console, but that didn't work for me. I bought my laptop with Vista installed and later reformated and used Windows 7. During formatting with Windows 7 I had some problems with my hard drive and found out it was dead so I bought a new one. I wanted to reformat with Windows XP,because Windows 7 is consuming more RAM that it is able handle and I wanted to use it for other programs. So I formatted with Windows XP Service Pack 3 but after first reboot a message appeared: "Error loading operating system" Reading here, I assumed that maybe I had installed it on the wrong partition and maybe having two OS now, so I used fixmbr but it is still not starting up. Anyway I am sure that is not the case of two operating systems. Is there any chance that when the computer designed to work with Vista you would face problems with Windows XP? Like not recognizing a hard drive?

• How can I setup apache+mod_proxy so when I connect to mod_proxy on interface X, it sends the traffic

  - by aspitzer

  We use a service that allots us X number of requests per IP and has allows us to setup 5 IPs with such a limit (I know.. it seems stupid they could not just up the limit 5x on one IP). Pretend I have a linux box with the following address on the internet: 66.249.90.104 - that is an Google IP and not mine... so feel free to try to hack into it :) I setup apache+mod_proxy as a forwarding proxy (ProxyRequests On). i.e. you can setup firefox to use 66.249.90.104:8080 as a proxy, and all firefox traffic comes out as 66.249.90.104. So far so good. Problem: Now I add more alias interfaces so the total looks like this: eth0: 66.249.90.104 eth0:1 66.249.90.105 eth0:2 66.249.90.106 eth0:3 66.249.90.107 eth0:4 66.249.90.108 I run apache+mod_proxy (single apache instance) which binds to all interfaces, but no matter which address I connect to use the forwarding proxy, all traffic goes out to the internet as 66.249.90.104 I have also tried running 5 different apaches, each binding to its own interface only, but that still sends the outbound request through 66.249.90.104. I was hoping to get it to work as follows: I connect to 66.249.90.108 and make a proxy request, and it goes out as 66.249.90.108. I connect to 66.249.90.107 and make a proxy request, and it goes out as 66.249.90.107. etc. Has anyone else had to deal with this issue? The fall back solution would be to just run apache on 5 separate boxes, but I would prefer it to all work on one box. Thanks!

• Picking a linux compatible motherboard

  - by Chris

  Last time I bought a new computer (I build them myself) I got a motherboard that had really poor linux support for a long time. Specifically the audio. I had to wait months before the kernel supported the on board audio chipset. That is exactly the situation I'm trying to avoid this time around. I have some specific questions about "server motherboards" actually. I looked at a few models of server motherboards by intel, and some random models on newegg. I wasn't able to see much of a difference from regular desktop motherboard other than most had two sockets, and support for much more ram. These boards seem more popular with Linux users. Why? AMD and Intel both have server CPUs as well. Some question, what's the difference? To make this question more concrete, I was looking at this this motherboard. The main questions about it that I can't answer are: Can I get a motherboard without on board raid and audio? I wanted to get a hardware raid controller and a PCI audio card. I thought a server motherboard would be cheaper and not have these "extras", since who wants an audio card on a server? Where can I found out about Linux support for the components on this board? "Intel ICH10R", "Realtek ALC889", "Marvell 88E8056" I'm buying this computer to work as a Linux desktop for a lot of compiling, coding and audio/video work, but I don't want to rule out the possibility of installing windows and playing some games at one point. (even if the last game I got has been sitting in its box unopened for almost a year). Is it a good idea to buy a "server motherboard" and play games on it, or are desktop boards better value for this? The ultimate solution for me would be a motherboard that had GPL divers for onboard LAN, a single CPU socket, lots of PCI express and PCI. USB 3.0, and no fancy hard disk controllers since I'll be getting a separate one.

• Burn bootable iso image to USB stick using dd: Won't boot (despite USB first in boot sequence)

  - by Nicolas Raoul

  I have installed Ubuntu on a Lenovo Thinkpad R500 2732, and I must update the BIOS. On the Lenovo website, I am offered this: BIOS Update Bootable CD for Windows 7 (32-bit, 64-bit), Vista (32-bit, 64-bit), XP - ThinkPad R500 I guess a bootable CD that would do a BIOS update is indeed what I need. (still wondering why it says "Windows" though... if it is bootable should not it be OS-agnostic?) Not wanting to waste a CD, I copied the image to my USB stick: sudo dd if=/home/nico/7yuj40uc.iso of=/dev/sdb1 bs=1M And rebooted, after making sure USB is first in the boot sequence. PROBLEM: It does not boot. Did I forget one step? Details about the iso image (readme): ls -lh 7yuj40uc.iso 25M file 7yuj40uc.iso /home/nico/7yuj40uc.iso: # ISO 9660 CD-ROM filesystem data '7YUJ40US ' (bootable) (Scroll to the right: it says "bootable") UNetbootin does not work because it is not a Linux image. Some people on the Internet advise to copy the content of the ISO and do other steps. This ISO has zero ISO content so it would not work. If I mount the ISO, I can see it contains zero files.

• Setting up 802.1X wireless connection on OSX

  - by hizki

  I am an OSX user, I have Snow Leopard 10.6.5 and an updated AirPort (version 5.5.2). I am trying to connect to my university's wireless network, but it has a 802.1x security that I am having trouble defining... Here there are instructions for connecting with Windows XP, Windows 7 and Linux. Can someone please instruct me what should I do to set up this network on my Mac? I have had previous success in setting up this network, but I have no idea what I did that made it work. Since I updated my AirPort (to version 5.5.2) it worked only seldomly and very slowly... Before the update, even when it worked it never remembered my password. Update: I have already tried to create a new "location", removed all the 802.1x user profiles and all the remembered networks, and made sure the in the TCP/IP tab 'Configure IPv4' is set to "Using DHCP". I also moved /Library/Preferences/SystemConfiguration/preferences.plist to my desktop in attempt to force the system to create a new set of settings. Still I can define the connection to work.

• Windows XP Installation problems

  - by Samurai Waffle

  I'm having trouble installing Windows XP on a computer... My friend gave me her old computer, it was riddled with viruses and ran extremely slow. I did my best to clean it out, and after a bit I discovered it had a boot sector virus. So I downloaded the Ultimate Boot CD (installed it on a flash drive), and ran Darik's nuke and boot to completely wipe the hard drive. I then tried to reinstall Windows XP from a USB drive... It doesn't work. The computer just stalls and never boots. The computers dvd drive doesn't work, so I borrowed a spare drive that another friend had, and tried to run a Windows XP cd. For a bit I got the stop 7B error, but now it just stalls like the USB drive does. Since then I've booted back into the Ultimate Boot CD, and ran partition magic. Repartitioned the Hard Drive, and copied the files on the Windows cd to the hard drive. I was wondering if there is any way I can make it run the setup.exe off the hard drive. I have the UBCD at my disposal, but have yet to come up with a way to do it. Any help is greatly appreciated.

• Unable to connect to CopSSH when running Windows service, works when running sshd directly

  - by Joe Enos

  I've been using CopSSH (that uses OpenSSH and Cygwin, so I don't know which of the three is the problem) as my SSH server application at home on Windows 7 Ultimate 32 bit. I have used it for about a year with no real problems, other than it sometimes takes 2 or 3 connection attempts to get through, but it's always worked within a few attempts. A few days ago, it just stopped working. The Windows service is still running, and I've rebooted, restarted the service, etc. with no change. On the client (using Putty on Windows), I get the message "Software caused connection abort". On the server, my event viewer registers the following: fatal: Write failed: Socket operation on non-socket I finally got it working, but only by executing sshd.exe directly from the command line on the server. No special flags or options, just straight execution, and then when I connect remotely, it goes through. I do have firewall and anti-virus software which appears to be configured properly, but the fact that things work when running sshd.exe also indicates that the firewall is fine. I thought the service and executable did exactly the same thing, but apparently there's some difference. Does anyone have any ideas on where I should look for the problem? If I can't find something, I suppose I can write a Windows service or scheduled task that fires off sshd.exe directly and ensures that it stays running, but that's kind of a last resort, since it's just wrapping around something that should already work. I appreciate your help.

• Name resolution not working with ipv6 on centos

  - by jolivier

  I just installed CentOs 6.3 on a server to be installed in a data center, but cannot get name resolution / curl to work. I know this is because of it trying to use ipv6, since ping google.com works, curl -4 google.com works, but not curl google.com. I removed the ipv6 adress from the interface and it does not change anything. This is very problematic since most system tools like yum fail at name resolution currently. Browsers like Firefox work because they might be using another tool for name resolution than the one use by curl. I managed to fix this on workstations by completely disabling ipv6 following tutorials like this one / hardcoding name resolution in /etc/hosts. But since I am here configuring a server which will be later installed in a remote data center, I would like not to mess up, understand what is going on and fix it properly. Besides, I will face the same issue with more servers to come so I would really appreciate your help in understanding this problem and how to solve it. I would be happy to provide more information if needed to help understand what is going on. The current network configuration is a small enterprise network, with a DNS server (let's call it A) configured once a long time ago. dig google.com and dig -4 google.com are both refused by the A DNS. But this is also true for my workstation on which curl is working (and yes they both use the same A DNS server). Indeed this faulty server and my workstation have multiple nameservers in /etc/resolv.conf, and the second one is working fine for both of them, so if I remove A from my resolv.conf everything works fine!

• Linking to network shares from Sharepoint pages

  - by Russell C

  So the place I work decided to set up a Microsoft Sharepoint 2010 server for task management and I (as the lowly entry-level intern) have been tasked with "figuring it out." One thing that the end users really, really, really, want is the ability to link to network shares (that are readable by anyone who will be using sharepoint) from a Sharepoint web page. In order to do this, I have edited the HTML manually with several lines that look like the following: <a href="file://server/share">Server Share</a> This works (sometimes) but the link reported by Sharepoint is often wrong and editing pages that contain these links will mangle the code such that when I open it, the code no longer looks like what it did when I last hit save (breaking all those links). Obviously this is not sustainable. I've been told by coworkers that "It worked that way at the last place I worked" but I haven't found out how yet. Any ideas on how this would work or am I barking up the wrong tree? None of the knowledge searches I've done shed any light on the sitataion. Thanks for any help! -Russell P.S. It should be noted that the file option in an href tag ONLY works in IE (which is a real bummer since we mostly use Firefox).

• Join ActiveDirectory (Win 2k8R2) to OpenDirectory(Snow Leopard)

  - by Tom O'Connor

  The vast majority of questions and so on regarding the interoperability of Active and Open directories involves getting Mac clients to see an AD and auth against it. What we'd like to do is get a Windows 7 workstation to auth completely against Open Directory. We tried setting it up as an NT4 type PDC, and that doesn't work satisfactorily. We tried using pGina and the LDAP backend, which allows Authentication, but has no support for Authorization, and as a result, if we mount an NFS Share, the user has the rights to do anything they damn well please. Not ideal for security (Totally bloody unacceptable, actually). We tried using a Samba server (newer version than on the Open Directory Server) as an intermediate, so that it knows about the LDAP server on the OD Server, but uses Samba 4 instead of v3. That didn't work either. We could login, but couldn't mount, and if we did, we had the same rights as with pGina. If we right-click the mounted drive in Windows, and have a look at NFS UID, it returns -2, not the correct (mapped) UID. So the final plan I've got is to use an Active Directory, inside a Windows 2008R2 Virtual Machine. What I want to achieve is to have the Active Directory sync it's user data from OpenDirectory (read-only would be fine). That way, we'd have the ability to connect Windows 7 clients to a "virtual domain" which would actually just grab information from OD's LDAP. All the information I've found is about how to go the other way. Does anyone know how we can do this?

• How can I fix Office Sharepoint Search service?

  - by unknown (yahoo)

  For some reason, in operations server services, Office Sharepoint Search Service is MISSING! Which means I cant get Shared services working, which in turn I cannot get, and I do not think I have ever got Usage and reporting to see who is visiting my website, counter and with what OS/ browser ETC. I dont think I have ever seen this work in the 2 years trying with sharepoint. So in essense I have two problems, most important SEARCH, second usage reports. When trying to search, all i get is unknown error. Nothing is in my event viewer at all. I have tried http://www.cjvandyk.com/blog/Lists/Posts/Post.aspx?ID=96 , in the comments on that site, on other person reports search is missing entirely and is going to uninstall. Im tired of uninstall sharepoint and resinstalling to fix an odd off issue. I have things setup with Team foundation server that took forever to get work and reinstallation is not my solution. As for usage reporting, this is what microsoft responds to the " Both Windows SharePoint Services Usage logging and Office SharePoint Usage Processing must be enabled to view usage reports. Please contact your administrator to ensure that these services are enabled. " error I cannot do all the steps since SSP needs to be setup which i cant above.

• Total newb having SSH and remote MySQL access problems

  - by kscott

  I don't often work with linux or need to SSH into remote MySQL databases, so pardon my ignorance. For months I had been using the HeidiSQL client application to remotely access a MySQL database. Today two things happened: the DB moved to a new server and I updated HeidiSQL, now I cannot log in to the MySQL server, when attempting I get this message from Heidi: SQL Error (2003) in statement #0: Can't connect to MySQL server on 'localhost' (10061) If I use Putty, I can connect to the server and get MySQL access through command line, including fetching data from the DB. I assume this means my credentials and address are correct, but do not understand why putting those same details into HeidiSQL's SSH tunnel info won't work. I also downloaded the MySQL Workbench and attempted to set up a connection through that client and got this message: Cannot Connect to Database Server Your connection attempt failed for user 'myusername' from your host to server at localhost:3306: Lost connection to MySQL server at 'reading initial communication packet', system error: 0 Please: 1 Check that mysql is running on server localhost 2 Check that mysql is running on port 3306 (note: 3306 is the default, but this can be changed) 3 Check the myusername has rights to connect to localhost from your address (mysql rights define what clients can connect to the server and from which machines) 4 Make sure you are both providing a password if needed and using the correct password for localhost connecting from the host address you're connecting from From Googling around I see that it could be related to the MySQL bind-address, but I am a third party sub-contractor with no access to the MySQL settings of this box and the system admin is assuring me that I'm an idiot and need to figure it out on my end. This is completely possible but I don't know what else to try. Edit 1 - The client settings I am using In Heidi and MySQL Workbench I am using the following: SSH host + port: theHostnameOfTheRemoteServer.com:22 {this is the same host I can Putty to} SSH Username: mySSHusername {the same user name I use for my Putty connection} SSH Password: mySSHpassword {the same password for the Putty connection} Local port: 3307 MySQL host: theHostnameOfTheRemoteServer.com MySQL User: mySQLusername {which I can connect with once in with Putty} MySQL Password: mySQLpassword {which works once in with Putty} Port: 3306

• Errors to do with modules when using net-snmp utils

  - by bob

  I was using the net-snmp packages that come with my linux distro (version 5.3.2.2), but wanted to do some work with the latest version of net-snmp (5.7), so tried compiling and installing the new source. It seemed to work ok but now I'm getting a load of errors when use net-snmp utils (snmpget, snmpset snmpwalk etc..) for example: $ snmptranslate -On SNMPv2-MIB::system.sysDescr MIB search path: /home/me/.snmp/mibs:/usr/local/share/snmp/mibs Cannot find module (SNMPv2-SMI) At line 6 in /usr/local/share/snmp/mibs/SNMPv2-MIB.txt Cannot find module (SNMPv2-TC): At line 9 in /usr/local/share/snmp/mibs/SNMPv2-MIB.txt Cannot find module (SNMPv2-MIB): At line 9 in (none) : <a lot of similar lines> : Cannot find module (NET-SNMP-VACM-MIB): At line 9 in (none) .1.3.6.1.2.1.1.1 From this I assumed perhaps that I was missing mibs from the 'MIB search path', so I looked at the first error 'Cannot find module (SNMPv2-SMI)', however it seems to be in the right directory: $ ls /usr/local/share/snmp/mibs/*SNMPv2-SMI* /usr/local/share/snmp/mibs/SNMPv2-SMI.txt And the same result for the other in the list.. so I'm wondering if anybody knows why it might not be finding the modules even though they seem to be in the search path?

• How can I get my SATA DVDs working again?

  - by user269051

  My hard drive crashed (WinXPpro), so I took a C drive from a broken PC. The new C drive is Win7pro. Motherboard is MSI K8N Neo4 Platinum, with 4 hard drives installed on SATA 1-4 (nForce4 Ultra); the two DVD drives are loaded on SATA 7-8 (Silicon Image SATARAID5). I've tweaked BIOS settings every which way. The closest thing to success was when each DVD had both a CD and a DVD icon, and blinked green. No CD or DVD could be read in either drive. I assume that the problem resulted from the fact that my new C drive does not have the RAID drivers? I've tried loading from the floppy (doesn't work). I can't boot off the DVD/CD, and switching the DVD's SATA cable to the SATA 3 slot (and pulling one of the hard discs) didn't work. I'd like to be able to use the other two available SATA slots for a mirrored RAID drive, and get my DVDs working again. Any suggestions?

• exim4 redirect mail sent to *@domain1.example.com to *@domain2.example.com

• Mod_rewrite (CakePHP routing functionality) forbidden after Snow Leopard upgrade

  - by Ryan Ballantyne

  Hello ServerFault, I am using the standard Apple-provided installations of PHP 5.3 and Apache 2 to do web development on a Mac Pro that I just upgraded to Mac OS X 10.6 (Snow Leopard). The upgrade went well enough, if I ignore the fact that it destroyed my ability to get work done. ;) After the update, the CakePHP application I was developing started giving me 403 Forbidden errors when accessed. Based on the errors in the log file, I've determined that Apache is choking on the mod_rewrite rules in Cake's .htaccess file. Here's the file, in its entirety: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ app/webroot/ [L] RewriteRule (.*) app/webroot/$1 [L] </IfModule> It's not that the rules themselves are wrong, but that Apache is forbidding the use of mod_rewrite altogether. All other pages on the machine work fine, and the 403 errors go away if I comment out the .htaccess file (but nothing works, of course). In my httpd.conf file, I've tried changing this: <Directory /> Options FollowSymLinks AllowOverride None Order deny,allow Deny from all </Directory> To this: <Directory /> Options FollowSymLinks AllowOverride All Order deny,allow Allow from all </Directory> ...which has no effect. I don't know much about Apache configuration files, and I'm quite stuck on this. In fact, I know little enough that I'm not sure which information about my setup is needed to enable people to provide useful answers. I'm just using the vanilla OS X setup, nothing fancy. Googling has yielded no fruits for me this time, so I'm turning to you. Any ideas?

• OSX root user keeps re-enabling itself on reboot

  - by geodave

  Running Snow Leopard. Completely inexplicably, I seem to have enabled the OSX root user by accident. I honestly have no idea how it happened, but if memory serves I was looking at the login pane (with my two user accounts) when I must have hit something, and suddenly the two accounts were replaced by one that just said "Other..." Clicking the "Other..." account allows me to type a username and password, but neither of the normal two accounts would work. Since I never set a root password, it wouldn't let me in that way either. So I booted into Single User mode and ran these commands: /sbin/mount -uw / fsck -fy launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist dscl . -passwd /Users/root newpassword and that let me login as root. Then, I went to System Preferences, Accounts, Login Options, clicked Join, Open Directory Utility, and lastly in the Edit menu I clicked "Disable Root User" Great, I thought, back to normal. Except rebooting, I still only have the Other... account visible, and the root password I set beforehand doesn't work anymore! I have to reboot into Single User Mode and go through the whole process again just to get back into the system (as root) How on Earth did I accidentally enable this? I didn't even know about the Directory Utility before now. And most importantly, why the heck would it be re-enabling the root user on boot? Thanks in advance to any help!

• Backup strategy for developer-focused Apple environments?

  It's interesting to see the technological split between structured corporate environments and more developer-driven/startup environments. Some of the Microsoft technologies I take for granted (VSS, Folder Redirection, etc.) simply are not available when managing the increasing number of Apple laptops I see in DevOps shops. I'm interested in centralized and automated backup strategies for a group of 30-40 Apple laptops... How is this typically done safely and securely, assuming these are company-owned machines (versus BYOD)? While Apple has Time Machine, it's geared toward individual computer backups and doesn't seem to work reliably in a group setting. Another issue with these workstations is the presence of Vagrant/Virtual Box VMs on the developers' systems. Time Machine and virtual machines typically don't work well unless the VMs are excluded from the backup set. I'd like a push-based backup process with some flexible scheduling options. I know how to handle the backend storage, but I'm not sure on what needs to be presented to the client systems. Due to the nature of the data here, cloud-based backup may not be a viable option. Any suggestions about how you handle this in your environment would be appreciated. Edit: The virtual machine backups are no longer important. They can be excluded from the process and planning.

• Route all traffic via OpenVPN client

  - by Ilya

  I've got OpenVPN client running on 192.168.0.3. What I'd like to do is route all the traffic from the second computer with 192.168.0.100 via OpenVPN client that's running on the first computer. My router ip is 192.168.0.1 Network topology: Windows computer with OpenVPN client: 192.168.0.3 Windows computer whose traffic has to be rerouted: 192.168.0.100 Router: 192.168.0.1 I want it to work in the following way: 192.168.0.100 computer => 192.168.0.3 computer => OpenVPN => 192.168.0.1 How can I achieve that by only modifying windows' routing table? I've tried entering the following into windows shell(on computer without VPN), which didn't work (it just dropped my internet connection): route delete 0.0.0.0 mask 255.255.255.255 192.168.0.1 route add 0.0.0.0 mask 255.255.255.255 192.168.0.3 Should I also setup the computer that has OpenVPN client running? Does it have anything to do with windows tcp forwarding? Thanks!

• Public-to-Public IPSec tunnel: NAT confusion

  - by WuckaChucka

  I know this is possible -- and apparently fairly common with larger companies that don't/can't route private addresses for overlap reasons -- but I can't wrap my head around how to get this to work. I'm playing around with pfSense, Vyatta and a Cisco 5505 right now, hardware-wise. So here's my setup: WEST: Vyatta outside: 10.0.0.254/24 inside: 172.16.0.1/24 machine a: 172.16.0.200/24 EAST: Cisco 5505 outside: 10.0.0.210/24 inside: 192.168.10.1 machine b (webserver): 192.168.10.2 So what we're trying to do is this: route traffic across the tunnel from machine A to machine B without using private addresses. i.e. 172.16.0.200 makes a TCP request to 10.0.0.210:80, and as far as EAST is concerned, it sees a src IP of 10.0.0.254. On WEST, I have your typical many-to-one Source NAT to translate 172.16.0.0/24 to 10.0.0.254 and that's confirmed to be working. Also on WEST, I have the following IPSec config: Local IP: 10.0.0.254 Peer IP: 10.0.0.210 local subnet: 10.0.0.254/32 remote subnet: 10.0.0.210/32 I have the reversed configuration on EAST. What happens when I make a request from machine A to 10.0.0.210:80 is that the SNAT translates the private address of machine A to 10.0.0.254 and it's routed out (and discarded at the other end) without establishing the tunnel. What I'm assuming is happening is that the inside interface on WEST receives a packet from 172.16.0.200 and since this doesn't match the local subnet defined in the tunnel configuration, it's not processed by the IPSec engine and the tunnel is not established. How do you make this work? Seems like a chicken and egg thing with the NAT and IPSec and I just can't wrap my head around how this can be done: can I say, "if a packet is received on the inside interface with a destination of 10.0.0.210, translate it to 10.0.0.254 before the IPSec engine inspects it"?

• Embedding a WMV file on the web via URL in a Powerpoint presentation

  - by Dave

  I've got a situation where I want to distribute a Powerpoint presentation to several people. I want to be able to embed several large videos in this presentation by linking to a URL, for the following specific reasons: the videos are highly confidential, and I would like to be able to delete them at some later date, but still allow them to see it in the presentation while it is online. I want to send the presentation via email (so it should be small), and put the links on a server with a faster upload speed Maybe I'd like to change the video at some point without changing the presentation One option that addresses #1 is to hook up a webcam and allow them to see video stream from the office, but our upload rate is too slow for this to be a viable option. I've tried embedding a video and giving Powerpoint the URL. It seems to work initially, because the first frame appears in my slideshow. However, when I play the slideshow, nothing happens. I looked at the network traffic on my computer, and nothing was getting downloaded from the remote server. Any suggestions on how to make this work, or how to at least satisfy the criteria listed above would be great!

• Prevent Roaming profiles from syncing certain elements

  - by user29919

  Hello everyone, I'm somewhat new to the Server 2008 front, and I'm afraid I've hit my first snag: I've set up roaming profiles, and they appear to be working too well. Is there a way to limit, ideally on a folder/object basis, what gets synced with a roaming profile? What I'm trying to do is: 1) stop my roaming profile from syncing desktop layout - I run a dual-screen desktop and a laptop, and it's really annoying to have to reposition everything after logging onto the laptop, because it forces everything onto one screen. 2) stop it from syncing registry variables - specifically, I want Visual Studio to load different setting files on each computer. Currently, the variable that contains that path is getting synced whenever I log in, so I get the settings from whatever box I last logged out from. 3) stop syncing the start menu - this one's not as big, but I'm noticing 'program not found' icons even for programs that are installed. they work when I click them - they just look ugly. I'm running Windows SBS 2008 x64 with two Win7 clients (x86 Pro, and X64 Ultimate). Is there a simple way to do that? Or am I trying to work too much against what roaming profiles are designed for? I could, of course, set up different profiles for the desktop and laptop, but that seems to defeat the point of roaming profiles entirely... Thanks in advance! Any help will be much appreciated =)
