• How to set up ProxMox 1.9 on VPN?

  - by Gnudiff

  Disclaimer: I have only rudimentary knowledge of VPNs. I would love to learn about them properly, however, at the moment I really need to make stuff work on short notice. I am trying to set up a ProxMox virtualization platform in an existing network. The network currently consists of several servers which have VMWare free edition. There is some sort of VPN defined in switch. In order for VMWare management interface to be accessible, there needs to be ticked a checkbox in the network settings for VPN and entered the VPN id. I didn't notice any such configuration option during ProxMox installation, so my Proxmox VE on the same physical server, using same manual IP settings (ip/nm/gw), is not accessible. As I understand I should touch the Proxmox's underlying Debian config in /etc/network/interfaces, but I have no idea, what should I aim for: do I specify the settings for eth0, do I make a virtual interface? How to make it accessible for both ProxMox VE and underlying future VMs? I read the ProxMox installation guide, but unfortunately it presumes better understanding of VPNs than I have. A config template or similar would be appreciated. Thanks in advance.

• How to whitelist external access to an internal webserver via Cisco ACLs?

  - by Josh

  This is our company's internet gateway router. This is what I want to accomplish on our Cisco 2691 router: All employees need to be able to have unrestricted access to the internet (I've blocked facebook with an ACL, but other than that, full access) There is an internal webserver that should be accessible from any internal IP address, but only a select few external IP addresses. Basically, I want to whitelist access from outside the network. I don't have a hardware firewall appliance. Until now, the webserver has not needed to be accessible externally... or in any case, the occasional VPN has sufficed when needed. As such, the following config has been sufficient: access-list 106 deny ip 66.220.144.0 0.0.7.255 any access-list 106 deny ip ... (so on for the Facebook blocking) access-list 106 permit ip any any ! interface FastEthernet0/0 ip address x.x.x.x 255.255.255.248 ip access-group 106 in ip nat outside fa0/0 is the interface with the public IP However, when I add... ip nat inside source static tcp 192.168.0.52 80 x.x.x.x 80 extendable ...in order to forward web traffic to the webserver, that just opens it up entirely. That much makes sense to me. This is where I get stumped though. If I add a line to the ACL to explicitly permit (whitelist) an IP range... something like this: access-list 106 permit tcp x.x.x.x 0.0.255.255 192.168.0.52 0.0.0.0 eq 80 ... how do I then block other external access to the webserver while still maintaining unrestricted internet access for internal employees? I tried removing the access-list 106 permit ip any any. That ended up being a very short-lived config :) Would something like access-list 106 permit ip 192.168.0.0 0.0.0.255 any on an "outside-inbound" work?

• Does Windows XP automatically reassemble UDP fragments?

  - by Matt Davis

  I've got a Windows application that receives and processes XML messages transmitted via UDP. The application collects the data using Windows "raw" sockets, so the entire layer 3 packet is visible. We've recently run across a problem that has me stumped. If the XML messages (i.e., UDP packets) are large (i.e., 1500 bytes), they get fragmented as expected. Ordinarily, this will cause the XML processor to fail because it attempts to process each UDP packet as if it is a complete XML message. This is a known short-coming in the system at this stage of its development. On Windows 7, this is exactly what happens. The fragments are received and logged, but no processing occurs. On Windows XP, however, the same fragments are seen, and the XML processor seems to handle everything just fine. Does Windows XP automatically reassemble UDP fragments? I guess I could expect this for a normal UDP socket, but it's not expected behavior for a "raw" socket, IMO. Further, if this is the case on Windows XP, why isn't the behavior the same on Windows 7? Is there a way to enable this?

• periodically unable to play media

  - by avorum

  So I don't know if this is right place to ask this at all but I've gotten good help here before so I thought I'd ask. For the last year or so periodically my computer would start refusing to play media. In browser players would say they were playing but they weren't. No audio and the video wasn't moving forward although it would show the first frame of the video to be shown. iTunes would act similarly, thinking it was playing without actually playing any music. This persists across browsers, various application categories, etcetera. It can often be fixed by rebooting but it is only a short term solution. Does anyone know of anything that might cause this erratic behavior? I'm using Windows 7 64bit. If additional information would help please ask. Alternatively, if this isn't the right site for this I would greatly appreciate some direction to a site better suited to my question. Thanks in advance for any help.

• Using NginX and Apache alongside for both static and dynamic files

  - by faridv

  Background: I've searched a lot and found these useful threads about using of Apache or NginX for static or dynamic files. But they are old (mostly about 1 or 2 years ago) and I think both webservers, specifically Nginx has had important changes in performance and usage. So I think take another look on these issue cannot be that bad. Nginx (for static files) and Apache (for dynamic content)? nginx better than apache for dynamic content? [closed] Apache or NGINX for PHP? Nginx as reverse proxy to Apache with only dynamic content? My question: I have a PHP web application with lots of dynamic files and lots of static contents (videos, images etc.) and it's currently running on a CentOS 6 server and Apache 2.2 since 2 months ago. In past few days, number of our site visitors have gained so fast and I just thought if this number continues to increase with current ratio, we need to change many things (web server, application, etc.) to prevent failures. Because of hardware limitations that we are facing, I thought that it's best for us to start with web server. Should I start with something else? Should I try to increase performance of my PHP application and forget about web server for now? (even if gonna take a long time!) Because of huge usage of .htaccess files (for redirection, rewrites, etc.), I think it's gonna be painful to migrate to NginX as default web server or maybe only for dynamic files. Does this mean that I can't even use Nginx as reverse proxy? I'm not sure latest stable version of NginX and PHP-FPM have a better performance over my current Apache and my limitations (too many things) won't let me to give it a try. Which one is doing better currently? What will I lose by migrating to Nginx? To make it short, what should I do?

• Spurious alleged file corruption on Windows 7

  - by Johannes Rössel

  Recently my Laptop sometimes warns about corrupted files on the hard drive (Samsung SSD PB22-JS3 TM). This has only happened so far when updating (or checking out) an SVN repository with either TortoiseSVN or the command line Subversion client. The fun thing is that the corrupted file has always been a .svn directory (although the directory entry may contain files in that directory too, if they're small enough?—?which should be the case with SVN). However, when looking into the warned-about directory I notice nothing strange or unusual and don't get any more warnings about it and another try (SVN stops updating once that error occurs?—?TortoiseSVN even with an appropriate error message) of updating the working copy works (well, mostly; sometimes it does it again, albeit with a different directory). Since the laptop is only a few months old I doubt the SSD is failing already—five months of normal usage shouldn't be too surprising. Also it (so far) occurred only with SVN updates on a large repository. Maybe that's too many writes in a short time and some part between the software and the hardware doesn't quite catch up fast enough or so?—?I don't know enough about this to actually make an informed guess here. Anyone knows what's up here? ETA: Note to add: I've run chkdsk (it seems to schedule itself anyway when this happens) and it didn't find anything out of the ordinary.

• Google Chrome - Issues with download dialogs using BinaryWrite

  - by Mila

  Hello, I have an empty ASP .NET page with the code behind to support downloading of PDF files. The page is called from a link-like web control that has NavigateUrl set to this page. In short, I am using the following for streaming: Response.Buffer = false; Response.ClearHeaders(); Response.ContentType = "application/x-pdf"; Response.AddHeader("Content-Disposition","attachment; filename="MyPDFFile.pdf"); byte[] binary = (dataReaderRemote[DataPDFFieldName]) as byte[]; //dataReaderRemote[DataPDFFieldName] has previously retrieved data if (binary != null) { MemoryStream memoryStream = new MemoryStream(binary); int sizeToWrite = CHUNKSIZE; //CHUNKSIZE=1024 for (int i = 0; i < binary.GetUpperBound(0) - 1; i = i + CHUNKSIZE) { if (!Response.IsClientConnected) return; if (i + CHUNKSIZE >= binary.Length) sizeToWrite = binary.Length - i; byte[] chunk = new byte[sizeToWrite]; memoryStream.Read(chunk, 0, sizeToWrite); Response.BinaryWrite(chunk); Response.Flush(); } } Response.Close(); IE as well as Firefox bring the download prompt window asking you whether you wish to open or save the file, while the user remains on the same page containing the link. However, Google Chrome opens a new blank tab and downloads the file automatically. Is there any way to prevent Chrome from opening the extra blank and therefore useless tab? I am using the Google Chrome version 5.0.375.55 (Official Build 47796) on Windows XP. Thanks in advance! Mila

• How to auto-cc a system email account any time a user creates an appointment

  - by Ferdy

  I will not bother explaining my full architecture or reasons for wanting this in order to keep this question short: Is it possible to auto-cc a certain email account any time a Exchange user creates an appointment or meeting in his own calendar? Is it possible using rules? Our Exchange 2007 server is outsourced, I cannot change the configuration or install plugins server-side Preferably, it still should work server-side, because users may use the Outlook client but also Outlook Web Access Is there any other way, perhaps using group policies? My conclusion so far is that the only viable way to accomplish this is to build an Outlook add-on. The problem there is that it will need to be managed for thousands of desktop users and that the add-on will not work when using another client (OWA, mobile). An alternative architecture could be to pull the information from the user's calendar on a scheduled basis. Given that we are talking about a lot of users, scalability is a major issue, this has also been confirmed by Microsoft. Can you confirm that my thinking is correct or do you have any other solutions?

• Intel Rapid Storage Technology (pre-OS) driver installation

  - by Nero theZero

  My desktop machine is built on Gigabyte GA-Z87-UD3H and Gigabyte provides the latest driver for Intel Rapid Storage Technology (IRST), which I installed after installing the OS. Same goes for my Lenovo Thinkpad-T420. And for both machine, checking the controller device under the IDE ATA/ATAPI Controllers section in Device Manager I see the driver has been updated to the latest version. I set the SATA controller to AHCI from BIOS On the desktop machine I have one WD 2TB BLACK & one WD 3TB Green I don’t use RAID, & no chance of using in near future, but according to Intel IRST improves performance in single disk scenario too. Now I have the following questions – What is the actual purpose of IRST (pre-OS install) driver that doesn’t get served with a post-OS driver that I installed? There must be some difference, otherwise there wouldn’t be a pre-OS version of the driver. Right? In the pre-OS procedure (loading the drivers at OS-installation time) after successfully completing the OS installation, do I need that post-OS driver? Because after installing from that one I got a quick launch icon that runs the IRST configuration application. Where do get that after installing the pre-OS driver? As it is “pre-OS”, when I load it at OS-installation time, does it updates anything at BIOS level or anywhere other than HDD? That’s because I’m going to dual boot Windows 7 with Windows 8.1, and after installing Windows 7 when I install Windows 8.1 & load the IRST driver for that, is there any chance of any “overwriting” or OS-incompatibility? In short, is there anything specific to follow while installing the second OS?

• duplicity fail: not promping for password: "Running 'sftp user@host' failed"

  - by Thr4wn

  I have two linode VPS accounts and I want to back up one onto the other (the reasons are mainly for fun and to practice server administration.) the short version Duplicity isn't even asking for my password, but immediately says "invalid SSH password" (but I can ssh into the other server). why? the long version When I run duplicity /home/me scp://[email protected]//root/backup I get Invalid SSH password Running 'sftp [email protected]' failed (attempt #1) Invalid SSH password Running 'sftp [email protected]' failed (attempt #2) Invalid SSH password Running 'sftp [email protected]' failed (attempt #3) And it says Invalid SSH password immediately with no opportunity for me to actually type the password. When I type duplicity full -v9 --num-retries 4 /home/me scp://[email protected]//root/backup I get Main action: full Running 'sftp [email protected]' (attempt #1) State = sftp, Before = 'Connecting to 97.107.129.67... [email protected]'s' State = sftp, Before = '' Invalid SSH password Running 'sftp [email protected]' failed (attempt #1) I can ssh into [email protected] fine, and in fact have the ip in known_hosts before I tried any of this. serer 1 (from which I'm running the duplicity command) is Linode's default Ubuntu 8 setup with only a handful of programs installed via apt-get. server 2 (represented by x.x.x.x) is literally only Linode's default Ubuntu 8 setup I previously tried using SystemImager -- would that have changed settings in a destructive way? (I have removed and rebooted since then) Isn't Duplicity supposed to prompt for password? Am I using it wrong? are there common mistakes/dependencies I need to know about? Is there any way that x.x.x.x could be setup that could make this not work (I used Linode's default Ubuntu 8 setup and barely )?

• Mainboard shuts itself off after half a second or so

  - by heishe

  Here's the problem: When I start the PC, the mainboard powers up, then stays that way maybe 0.2-0.5 seconds, and then shuts off again. I say mainboard, and not PC, because I removed all the parts from the system and disconnected everything but the mainboard power supply (the broad 12 pin thingy). When I have the other parts (cpu, graphics card, ram, etc.) installed and connected, the basic behaviour stays the same, but now the mainboard runs for about 6 or 7 seconds (this is a guess) before shutting off. This all started when my monitor wouldn't receive a video signal today, without giving POSTs, so I took the graphics card and the RAM out to see if it changes anything. It didn't, except that from that point on the mainboard would start to have this behavior where it just stays on for a very short time and then shuts off again. I already tested it with a backup PSU - same behavior. What could this be? I'm thinking it can't be on a physical level (transistors burned through or something like that), since then the mainboard either shouldn't start at all or it should detect hardware failures in non-essential parts of the syste and start beeping. Sorry, I forgot to mention. It's an MSI P67A-C43. I already checked the capacitors if someone popped, but I can't find anything. I also tried resetting the cmos, but that didn't change anything.

• Data recovery on a corrupted 3TB disk

  - by Mark K Cowan

  Short version I probably need software to run a deep-scan recovery (ideally on Linux) to find files on NTFS filesystem. The file data is intact, but the references are no longer present. Analogous to recovering data from a "quick-formatted" partition. Hopefully there is a smarter way available than deep-scan, one which would recover filenames and possibly paths. Long version I have a 3TB disk containing a load of backups. Windows 7 SP1 refused to detect the disk when plugged in directly via SATA, so I put it on a USB/SATA adaptor which seemed to work at first. The SATA/USB adaptor probably does not support disks over 2.2TB though. Windows first asked me if I wanted to 'format' the disk, then later showed me most of the contents but some folder were inaccessible. I stupidly decided to run a CHKDSK on my backup disk, which made the folders accessible but also left them empty. I connected this disk via SATA to my main PC (Arch Linux). I tried: testdisk ntfsundelete ntfsfix --no-action (to look for diagnostically relevant faults, disk was "OK" though) to no avail as the files references in the tables had presumably been zeroed out by CHKDSK, rather than using a typical journal'd deletion). If it is useful at all, a majority of the files that I want to recover are JPEG, Photoshop PSD, and MPEG-3/MPEG-4/AVI/MKV files. If worst comes to worst, I'll just design my own sector scanner and use some simple heuristic-driven analysis to recover raw binary blocks of data from the disk which appears to match the structures of the above file types. I am unfamiliar with the exact workings of NTFS but used to be proficient at recovering FAT32 systems with just a hex-editor, so I can provide any useful diagnostic information if you let me know how to find it! My priorities in ascending order of importance for choosing the accepted answer: Restores directory structure Recovers many filenames in addition to the file data Is free / very cheap Runs on Linux Recovers a majority of file data The last point is the most important, but the more of the higher points you match the more rep you'll probably get :)

• Disabled FRS replication on a DFS link, but the targets still list the replica set in their FRS conf

  - by Graeme Donaldson

  It's been a while since I've had to deal with the wonders of FRS, so I'm doing some testing to refresh my memory. This is what I've done so far. I am stuck with FRS rather than DFS-R for the moment since not all of my link targets are running R2. Created a domain-based DFS root, hosted on 4 servers. Created a DFS link under the root, targeted at 2 servers. The shares on both servers were empty. Dropped about 500MB of data into the target folder on one server and waited for replication to complete. Added/removed/modified files on both targets and confirmed that changes are replicated within a few seconds. Deleted the contents of the target folder on 1 server and waited for the other server to replicate the deletion. All of this worked perfectly, so now I want to remove my DFS link since I only created it for testing purposes. This is where it gets weird. I'm pretty sure that in the past I've disabled replication on the DFS link and after a short amount of time each target would log an info event in the FRS event log, something along the lines of "this server is no longer a member of replica set X". I have waited about 3 hours and I haven't seen this happen. ntfrsutl ds tells me that the server is not a member of any set, which is expected because when I disable replication on the link, the AD attributes on the computer object are removed. The weird part is... ntfrsutl sets still shows me the replica set, with all the properties, etc. So it seems like the FRS-related attributes of the target server's AD object are gone, but the FRS service for some reason hasn't removed the replica set. Can anyone see what I have done wrong?

• 1 document pending in printer queue in System Tray that won't go away

  - by White Phoenix

  Edit: I didn't want to do it, but I restarted my computer - cleared the problem right away. Though if I were running a Windows 2003/2008 server, I would hate to have to restart the domain controller just to get rid of this irritating problem. If I run into this problem again, I'm going to try that remove printer/reinstall printer thing. Thanks for your help @Psychogeek. Points for your attempt. Running Windows 7, 32-bit Professional. My printer is an HP OfficeJet Wireless 8500. It's connected to my network wirelessly through TCP/IP as a standalone device. I was having some print problems awhile back and had to do some print spooler stuff as part of my troubleshooting (stopping the Print Spooler service, clearing the print spooler files from C:\Windows\System32\spool\PRINTERS and then restarting the service). I've finally narrowed it down to it being application specific, so that's that. However, as a leftover from all that troubleshooting, my printer icon is stuck in the tray - when I mouseover the icon, Windows says that there is 1 document(s) pending for my username. However, when I open up that printer's queue, there's nothing in there. I restarted the Printer Spooler service and also checked C:\Windows\System32\spool\PRINTERS if there's anything in there - nothing. I did a quick Google search and an answer from one of those "reps" at the Microsoft Socialnet site says for me to uninstall and reinstall the printer. The funny thing is, when I send print jobs, they print just fine - that 1 mystery document stuck in queue isn't stopping anything from happening. Short of having to do that, are there any other quick troubleshooting steps I may be missing?

• Export NFS path containing "-" (dash)

  - by qdot

  I'm in a bit of a pinch with NFS exports file. Specifically, I can't find a way to export a directory containing "-" in the path name. Manual (exports(5)) states: Also, each line may have one or more specifications for default options after the path name, in the form of a dash ("-") followed by an option list. The option list is used for all subsequent exports on that line only. It then states: If an export name contains spaces it should be quoted using double quotes. You can also specify spaces or other unusual character in the export name using a backslash followed by the character code as three octal digits. Unfortunately, that is not the case. Specifically, if the pathname contains "-", either verbatim, or with \055 or is enclosed in double quotes, it still refers to the name without "-" Any ideas? I have a large number of directories, all of the form /vol/buildsystem-s3c2440 /vol/buildsystem-tao3530 and I'd prefer to have them all available as nfs exports. Short of replacing the "-" with "_" everywhere in the scripts, can it be done with "-" ?

• Boinc permissions problem on OS X

  - by Erik Vold

  I installed boinc 6.10.21 on my OS X 10.5 in order to upgrade from a 6.6 version that I was running today, and I am the admin user, and I was logged in as the admin user. As I was installing 6.10.21 I was asked if non admin users should be allowed to use Boinc, and I said 'yes' to this. Then when I tried to open Boinc I got a message like the following: "You currently are not authorized to manage the client. Either re-install and allow non-admin users or contact your administrator to add you to the 'boinc_master' user group." So I tried to reinstall first, and I was not asked if non admin users should be allowed to use Boinc.. so I retried a few times and got no different result.. So I downloaded 6.10.43 and installed that, and again I was not asked if non admin users should be allowed to use boinc.. and when I tried to run Boinc I got the same message like: "You currently are not authorized to manage the client. Either re-install and allow non-admin users or contact your administrator to add you to the 'boinc_master' user group." So I did a Google search trying to figure out how to add my admin user to the bonic_master user group and found this which suggested I run the following in terminal: "sudo dscl . -append /Groups/boinc_master GroupMembership <your user's short name> CR" So I did this and now I get the following error: BOINC ownership or permissions are not set properly; please reinstall BOINC (Error code -1200) So I reinstall and I am ever asked the question about allowing non admin users again, and I still get this error message every after every reinstall attempt.. What should I do?..

• Windows XP consuming drive letters

  - by billdehaan

  This one's a bit of a stumper. I'm running XP SP3, current with all fixes, etc. My problem is that I can assign a drive letter to a container file (explained below), it works just fine. But once I close the container, the drive letter is no longer available until the next boot. I've got some confidential data that I've placed in a container volume. I've used TrueCrypt (www.truecrypt.com) and FreeOTFE (www.freeotfe.org), with both installed and portable versions for both, with the same result. I open the container file, assign it to a drive letter (say R:), and run some portable apps that are within the volume. When I'm done, I close the container, and the drive letter is released. Fine so far. However, when I attempt to re-open it, the previous drive letter (in this case R:) is no longer available. It's not mapped to anything, it's just unavailable. Even attempting something like "subst R: C:\" returns "Invalid Parameter - R:". I can use the S: drive, no problem, but the next day I have to use T:, then U:, etc. Eventually, I have to reboot to reclaim all of of the drive letters. Unfortunately, everything I've read about drive letters relates to USB assignments, which doesn't apply here. I've tried the "show hidden" command (set devmgr_show_nonpresent_devices=1) with no success. And the Disk Management tool doesn't apply either, since it's not a physical drive. Does anyone know where Windows keeps the list of drive letters? And is there anything short of a reboot that can be used to reset it?

• What is the collaborative screen shot/diagramming application recently featured on Hacker News and p

  - by wonsungi

  A few days ago, I saw this video for a screen capture application. I'm pretty sure I followed a link from Hacker News, possibly to a Life Hacker article. The video was very short, but demonstrated how the application could be used: The application was basically a movable/resize-able view port with a button. When the button is pressed, the contents of the view port are saved to an image (basically a screen capture.) The interesting thing is what you could do after that point. One of the specific examples from the video browsed to Google maps street view, grabbed a photo of an intersection, then scribbled notes about where to meet and where the restaurant was in colored "marker." Another example shown was grabbing a house layout from from CAD tool, then scribbling notes on it. The last part of the video showed several possible uses being scrolled through the application's view port. Now, it seemed it was very easy to share these images with other people because there was some type of integration, either with their own site and/or common social websites/chat services. The application was shown running on both Windows and Mac. edit: I think there was an iPhone app, as well. Anyone know what this application is? I tried searching Google, Hacker News, and Life Hacker already. It is not Jing.

• Networking DOS within Windows 7 XP Mode, with a Windows XP/7 Networked Share

  - by theonlylos

  For awhile now, one of my clients has been stuck with Corel Paradox 4.0 (it used to be the biggest database system in the DOS days, until Microsoft released Access in the early 90's) so for awhile I've managed to keep it on life support on Windows XP for a few years, however since switching to Windows 7 x64, I've had to resort to using XP Mode as the sandbox to keep it up and running. While I am able to run Paradox as usual in XP Mode, I'm having a serious issue where if I try connecting the install to the network share (which is located on the Windows 7 portion of the system), Paradox keeps exiting because it says the serial number is invalid. Now, I know for a fact that this is an issue with the virtual loopback adapter and also having the VM linked to the physical ethernet adapter -- and while I have solved this issue before, most of my fixes have been bandages since after a few weeks the issue pops up again. Long story short, I wanted to ask if there is a permanent way to link a DOS program to a network share address. For example, when I try doing \tsclient\paradox (the Windows 7 Address) I keep getting an error saying I need a valid network address. I've tried mapping that folder to various drive letters such as P:\Paradox -- but for some reason that keeps failing over time. For what it's worth, Paradox uses a .SOM file to store the network settings, however it isn't editable in Notepad but rather it's controlled by a wizard in Paradox. But if that extension rings any bells, I'd welcome any insights.

• Swapping Function (Fn) and Control (Ctrl) Keys on Lenovo ThinkPad W500

  - by Howiecamp

  I'd like to swap the Fn and Ctrl keys on my ThinkPad W500 (like many others! See: How can I switch the function and control keys on my laptop? and Intercepting the Fn key on laptops) Numerous folks indicate that Windows doesn't register the Fn key as a keypress but using Mihov ASCII Master 2.0, that gives the ASCII value of a keypress, I see the Fn key returning FF (perhaps FF in this case means 'not registered'). I also see that keys like Ctrl register with one ASCII code when pressed alone and another when pressed in combo with another key. Fn will only register when pressed alone, so Windows definitely isn't seeing the combo. This took a solution like AutoHotKey off the table. I ran KeyTweak (which shows you the hardware scan codes of a keypress and the Fn key registerd as 57443). Using this program I remapped Fn to the Ctrl key; this worked perfectly. However, I suspect that because of the issue in #1, the combo of, for example, Fn + C did not execute a copy. Short of retraining my pinky I'm actually considering removing the keyboard and resoldering the connections to swap those keys. I'd love to get some input as to the root technical issue(s) and possible solutions here.

• Unable to connect to shared (iscsitarget) dvd-rw drive on ubuntu karmic box

  - by develop7

  Preface: I have desktop with DVD-RW drive that runs primarily on Linux (namely Ubuntu 9.10). My wife has netbook that rins Windows XP with no cd/dvd drive. There's also LAN through our ADSL modem/router. I've "ported" (actually, I've just grabbed sources and ran dpkg-buildpackage) iscsitarget package from Ubuntu Lucid to Karmic (here are packages), installed it (sudo aptitude install iscsitarget; sudo m-a a-i iscsitarget) and configured it in the following way (/etc/ietd.conf): Target iqn.2020-01.local.develop7-desktop:storage.disc.dvdrw Lun 0 Path=/dev/sr0,Type=blockio #I've skipped commented lines Also, I've opened port 3260 with ufw: $ sudo ufw status | grep 3260 3260 ALLOW 192.168.1.0/24 But (here's the trouble) I still can't connect to this target from Windows box. Microsoft Software iSCSI Initiator tells "Logon failure" upon connect attempt. After unsuccessful connection attempt I've noticed this line in dmesg | tail's output: iscsi_trgt: ioctl(299) invalid ioctl cmd c078690d So the question is — what's wrong with my config/iSCSI target/whatever else? Or, in short — what I'm doing wrong? Thanks in advance.

• Windows Server 2003 SBS domain in multiple sites

  - by E3 Group

  We have about 25 employees in our current office and are looking to open up another office in another capital city housing about 15 employees. In our current office, we are running a domain hosted by a 2003 SBS server and I've been tasked by the boss to expand our infrastructure to the new office in the cheapest way possible (cheapest way in the short run that is, because my boss doesn't think more than 6 months ahead). So I'm looking to get a second hand server and have it run Server 2003 Std with exchange server 2003. These are the things that it needs to do: Replicate shared folders that are hosted in the parent LAN. Deliver emails hosted in the parent Exchange Server Somehow link up with the parent domain controller and push the AD to the remote site I'm pretty sure 3 is impossible but the DC would be available if a VPN connection is present, right? On that note, would I be looking at hardware VPN connections? I'm not sure how to deploy the new site as this is my first time doing it and i'm making it especially difficult for myself, seeing as the AD and DC is on an SBS server. Would I first start by establishing a VPN connection and then joining the new server to the domain? Will things 'just work' if I install exchange onto the new server and point outlooks to it? and how would I be able to replicate shared folders?

• Python coding with VLC player (quite a basic query I expect)

  - by Todd

  I'm fairly new to the whole coding realm so my knowledge is fairly limited, and I can't seem to find any basic tutorials on how to use scripts with VLC player. More specifically, the reason I'm asking here is because I stumbled across a post on this site about playing random clips from random videos on VLC player automatically. This is the forum post: Playback random section from multiple videos changing every 5 minutes My situation is similar to this lovely gentleman's was, though he clearly knows a lot more about coding than I do. In short, I'd like to copy this coding into a file of some sort and apply it to VLC player myself. Only I'm not sure what file type I'd have to save it as (I have Python by the way, and I tried saving it as a .py file but I didn't know if it was correct or where to go from there). Additionally, I'm not sure how to get VLC to "read" the script, so to speak - is there a specific location the file needs to be, and do I run the script from another program or through VLC? I'll reiterate that I'm relatively new to this, so if anybody would be so kind as to post a quick list of steps on how to save/place the file and use it with VLC player I really would appreciate it! P.S. I'm not computer illiterate, I'm fine with most programs and I'd understand if you just said things like "C:\Program Files (x86)\VideoLAN\VLC\plugins" or "in VLC, select Tools Plugins and extensions", I just wouldn't catch on to anything about adding a line of coding that does something without being told exactly what to write! Many thanks in advance! :) Todd
