• Does MS Forefront TMG cache authentication?

  - by SnOrfus

  I'm testing a client machine that makes requests to a biztalk server using a forefront machine as a web proxy. Upon first test I put in an invalid name/password into the receive port and received the correct error message (407). Then, I set the correct name/password and everything worked correctly. From there, I kept the correct information in the receive port but put an invalid name/password into the send adapter but the process completed successfully (should have failed with 407). I've ensured that both the recieve and send ports are not bypassing the proxy for local addresses. So the only thing that seems to make sense is if TMG is caching the authentication request coming from the machine I'm working on. Is this thinking correct, and if so, does anyone know how to disable it in TMG?

• Accessing IPv6 router interface from a minimal Fedora installation?

  - by Zack

  I've recently installed Fedora 16 and am trying to set up a simple apache server. The only problem I've run into so far is that I'm unable to access my router's web interface from any box on my network. It assigns addresses via dhcp, and the router always responds to a ping. The server is also picking up an IP from the router on the proper subnet. Now, all I really need to do is forward a port, however I am receiving "Unable to connect" through the web interfaces and "connection refused" via telnet. What are my options, and how might I go about troubleshooting this? Will I need the server's ip to be static in order to change these settings? The router is a "Netopia" model, if that helps.

• Create Vmware image from exisiting Ubuntu installation

  - by Tathagata

  I have been stuck on a netbook since last year due to budget constraints, but finally managed to get a decent laptop from a very generous person. Now my ubuntu installation in the netbook has all my development tools, libraries, personal mediawiki, other servers and things that I'm only reminded when the command line complains. I can always ssh into my netbook, but don't want to carry both the computers all the time. Is it possible to create an image from my netbook Ubuntu and use it out of the box in a Vmware player in the new laptop?

• Refurbished System Windows License Key and OEM Media

  - by Timothy R. Butler

  According to this question, it is legal to use a Windows 7 OEM license that is presently installed as a 32-bit install with a 64-bit version of Windows 7. With that in mind, I purchased several refurbished systems through TigerDirect. When I received the computers today, I found that they have a Windows 7 license key attached to them that says it is a "refurbished key." A flyer in the box also seemed to imply that this key would not work with regular OEM media. Has anyone tried using regular OEM media with a refurbished key? I had hoped to create a new 64-bit WIM image that I could use on these systems, but I don't want to try replacing the default install with this new 64-bit install only to find that the key won't validate. If it requires a special customized image, is it possible to convert another type of Windows 7 disc into the required sort much as one can convert a retail disc to an OEM one (and vise versa)?

• Wireless networking on Gnome on Ubuntu 9 / 10

  - by WaveyDavey

  So here's my problem: I have some netbooks (ASUS eee, and ACER Aspire Ones) that I've been tasked to set up as kiosk machines, locked up tight for normal users. I am a command-line, server man, so this gnome malarkey is all a bit new to me. I found a lovely 9.04 kiosk livecd that installs and runs exactly as I want it to, but I can't get the wireless working. So I dropped on a full 10.4 distro, and wireless works straight out of the box (so hardware is good) - all I needed to do was right-click on the network connection icon, enter my SSID and password (WPA/WPA2) and away it went, perfect. Further investigation on 10.4 distro shows that /etc/networking/interfaces is virtually empty (just auto lo iface lo inet loopback in it), even after I have set up the wireless thru the gnome taskbar applet (is that the right word?). So where does gnome / ubuntu store the network settings to bring the blasted wireless connection up, and what do I need to do on the kiosk version to get wireless running?

• Changing location of ClamAV logging files

  - by GrumpyCanuck

  I've run into a weird problem with ClamAV that I have been unable to resolve, due to a incredibly non-informative error message. I've installed ClamAV via aptitude on an Ubuntu box (ClamAV 0.96.5/13202 according to the system) up on EC2 and it is 100% stock. We have an additional drive mounted under /mnt where we put all our log files. When I start it up with the log files in the default location, it runs just fine. However, if I change the configuration file from /var/log/clamav/clamav.log to /mnt/clamav/clamav.log I get the error ERROR: Can't open /mnt/clamav/clamav.log in append mode (check permissions!). ERROR: Can't initialize the internal logger It's the same file with the same permissions on it, just in a different location. Any thoughts or tips on how to resolve this problem would be greatly appreciated.

• Cyrus IMAP: Unable to connect to remote host: Connection refused

  - by Nick

  I'm working on setting up a Cyrus 2.2 IMAP server on Ubuntu Server 9.04. If I telnet from the server itself: # telnet localhost imap I get: * OK IMAP Cyrus IMAP4 v2.2.13-Debian-2.2.13-14ubuntu3 server ready Which is what I should be seeing. If I try from another machine on the network: telnet 192.168.5.122 imap I get: telnet: Unable to connect to remote host: Connection refused To the best of my knowledge, there is no firewall running on the box. I've tried restarting the saslauthd and cyrus2.2 daemons, with no effect. What else can I try?

• Restore monitor detection to one only or restore start menu to bottom [Windows 7]

  - by Mark

  I have a co-worker that is no longer able to see his start menu. He used to have it pinned to the left edge of his screen. I tried to troubleshoot it a bit and discovered if we do Windows + R then "cmd" [enter] the command prompt opens (but we don't see the start menu or run box), meaning the start menu is somewhere, just off screen. Restarting doesn't help. Is there some way to force Windows to think it only has a single monitor? It seems to "think" it has two but there's only one and we can get the Start menu back. Or, is there a way to restore the start menu to the bottom? Additional info We are able to right-click the desktop for display settings, etc. We can also get into Windows Explorer (via Ctrl + E) so if we need any of that to restore settings we can do it.

• Replication in PG 9 between Windows and Linux boxes

  - by mlaverd

  I have PostgreSQL 9 running on Windows 2003 SP2. I am trying to replicate it on a Fedora 12 system running PostgreSQL 9 as well. I am hitting this error message: /usr/pgsql-9.0/bin/postgres -D /var/lib/pgsql/9.0/data/ -p 5432 2011-02-11 17:43:26 ISTFATAL: incorrect checksum in control file Because of firewall restrictions, I could not follow the official instructions to the letter. Instead, I zipped the contents of the data directory when the server was offline and copied that to the Linux box. I ran a sha1deep on both directories and there were no mismatches. I changed the rights so that only the postgres user and group had access to the files. Now, what can I do for replication to work? I tried with a 'pg_dumpall', but the system complains that the database IDs do no match.

• How to change MySQL data directory?

  - by Jonathan Frank

  I want to place my databases in another directory, so I can store them in an ESB (elastic block storage, just a fancy name for a virtualized harddisk) together with my web-apps and other persistent data. I have tried to walk through a tutorial at http://crashmag.net/change-the-default-mysql-data-directory-with-selinux-enabled. Everything seems fine until I type this command: # semanage fcontext -a -t mysqld_db_t "/srv/mysql(/.*)?" Then the command fails and tells me that mysqld_db_t is an invalid SELinux context even if the default MySQL data directory is labelled with this context. I am running Fedora 15 on Virtualbox (behaves like an ordinary x86-compatible box) and Amazon EC2 (based on Xen) so the tutorial should be compatible. It is also worth to mention that turning off SELinux globally or just for the MySQL process is not an option, because such a solution will decrease the security of the system if a hacker gains access to the system via the MySQL server. I have never seen this problem before I changed to the Redhat/Fedora architecture, so it could be a distribution specific issue. Any help is highly appreciated

• Convert MSDN Windows 7 Enterprise installation to Ultimate

  - by stimms

  Related question: When reinstalling Windows 7, does the language, version, architecture (64-bit or 32-bit) or source (OEM, retail, or MSDN) matter? Unthinkingly I installed Windows 7 Enterprise on my development box at work rather than the Ultimate version. Now windows is complaining that it is unable to activate because it can't contact a KMS (Key Management Service) which my company doesn't have. Is there any way to change this install such that it believes it is Windows 7 Ultimate and will take an ultimate key? I have MSDN so the licensing is not an issue.

• User profile and desktop unclickable and unviewable from windows explorer

  - by Abel

  Situation: Windows Vista, latest updates. After restarting to complete an installation, I find myself looking at a totally black windows desktop without any icons. The start menu and taskbar, including quickstart icons, appears. Some, but not all task bar tray icons appear. The systems seems stable. When I open Windows Explorer and click "desktop" in the folder treeview, the cursor immediately jumps back to the previously selected item. No error. Same when clicking on my user's profile or my documents. When I try "save as" in, say, Notepad, nothing happens, the dialog box (which defaults to "my documents") doesn't even show. Again, no error. Nothing serious afaict in the event log. Typing something Start Search shows "Search failed to initialize". Anybody ever encountered such abomination?

• NIC models for HVM guests in Xen 4.0

  - by Jed Daniels

  Is there a list of NIC models that I should use with various HVM guests in Xen 4.0? Is there even a list of possible choices for the model=field? I'm planning on running both Windows and FreeBSD guests on the particular Xen box that I'm configuring now, and ideally I'd like a setting that can work on both of them and get me gigabit speeds without a lot of extra hassle loading special drivers (similar to VMware's e1000 NIC option). Any suggestions? The vif line I'm currently using in my config is: vif = [ 'type=ioemu,bridge=eth0,model=ne2k_pci,script=vif-ovs' ] This works in my Windows XP SP3 VM, but is only recognized as a 10Mbit interface. Changing to model=e1000 or model=i82557b resulted in Windows not being able to find a driver for the NIC.

• DNS Settings in Cisco Wireless Lan Controllers

  - by Braden

  The WLC is a 2100 series and I have looked back and forth through the entire web interface. Originally the idea was that the gateway should be the DNS controler and the WLC pointed directly at the gateway. For some reason, random clients are having DNS specific issues when it comes to seeing certain shares around the network. The problems are also very intermittent. Aside from going to each box and implementing a static DNS is there ACTUALLY a DNS setting lodged into the WLC settings (and I am being a numpty and can't find them) or am I stuck with performing the config 1 by 1?

• Is it possible to a VM inside a VM (e.g., KVM on Vmware)?

  - by lorin

  I'd like to do some development on Eucalyptus, an open source project which provides an Amazon EC2 interface for launching virtual machine instances on a collection of privately managed nodes. I'd really like to be able to do some of the development on my desktop, rather than having to deploy Eucalyptus on our shared local cluster each time I make a change to the source code. (Especially since there are a group of us sharing that test cluster). Unfortunately, my desktop machine is a Mac, which won't run Eucalyptus natively. I do have VMWare Fusion, and it would be really nice if I could do my Eucalyptus testing inside a VMWare instance. The problem is, to test out Eucalyptus, it will have to launch (KVM or Xen) VM instances. I've got no idea if it's possible to actually launch a KVM or Xen instance inside a VMWare instance.

• Is it possible to disable ARP in Windows 7

  - by DriverGuy

  I have a unique requirement where I need to disable ARP on a Windows 7 box. In previous Windows versions you could modify the ArpRetryCount in the registry (and set it to 0), but this does not work in 7 (nor does it exist). Does anybody know how, or if this is possible? I've been asked to elaborate this more and I'm not quite sure how. I want to switch off ARP (including gratuitous arp) on Windows 7 for a project I'm working on. You can do this in Linux by simply adding '-arp' when you bring up an interface, but you cannot do this in Windows 7. You could in previous versions by modifying the registry, but this does not work any more. If the fine folk here aren't sure then I don't like my chances...

• Looking for Inneroffice Access Tool, Workstation to Workstation

  - by nicorellius

  This may be a simple question to answer, and I apologize if it's a duplicate. I looked through the suggestions and nothing jumped out at me as the right answer, so here goes: My office has several workstations, Macs and Windows boxes. We do have a firewall and a VPN solution, so getting in to the network from outside is easy. Likewise, we use GoToMeeting for demos and when we help our customers with their issues. But we have one workstation that has certain testing tools on it, and instead of walking across the office to this machine, I'd like to access it from my desk (and monitor it). I will need to open a command line and run commands. I could start a GoToMeeting and do it this way, but that seems overkill and clunky. Is there a simpler tool that allows pseudo-remote access within the same office/network for this kind of access?

• Windows Resource Monitoring Programs

  - by Sal

  I work at a small tech start up managing websites with our own in house server side code. (In production, we use Windows Server 2008 boxes, running Java 6. In our dev boxes, we use Windows 7 running Java 7.) Recently, we had an issue where some of our boxes in production failed, and we didn't have means of trouble shooting, since we keep little to no monitoring logs about a given box's CPU/memory/RAM usage, etc. So, I'm wondering if there is some commercial/freeware that's the standard for performance monitoring/logging. Essentially, I'm just looking for an analytics system that is similar to the Windows Task Manager or the Resource Monitor, that serializes all of its data periodically. Ideally, I'd like to find a program that's also extensible, in case I'd like to add addition monitors in the future.

• Load-balancer options

  - by toolkit

  I am looking at a number of possible options for load-balancing. So far, I am constrained to the following options: DNS server load-balancer, balancing to a cluster of tomcat servers, with terracotta for session replication. Pros - don't have to buy new kit. Cons - DNS lb can keep directing to a broken server. Hardware load-balancer, direct to cluster of tomcat servers. Pros - could have second box for failover lb. Cons - expense. Apache server load-balancer. Pros - apache's lb polls for broken servers. Cons - apache server is single point of failure, plus need to buy another server. Are there any other options I should consider? Thanks. Update: Thanks for all the answers so far +1's all round. Not accepting an answer yet, to keep more ideas coming.

• Sync files between Mac, PC and Linux automatically

  - by Siriss

  Hello everyone- I have a MacBook Pro, a Windows 7 desktop, and a Fedora 13 netbook. I have been searching far and wide for an automatic solution to sync files (pictures, music, docs, etc...) between the three when they are all on the same LAN. To better explain, when I get home and turn my MacBook on, I want it to sync automatically any file changes to Windows 7 and the netbook. Likewise if I make changes on my Windows 7 box, I want them to be reflected on my Mac. I can use rsync, but it is not automatic as far as I can tell, and I would use Dropbox but I have a lot more that 2 gigs and do not want to pay. I also do not need internet syncing. I just want local LAN. Does anyone have any ideas? Thank you very much in advance.

• Can't Shut Down computer with windows 8 Release Preview

  - by Bram Winda

  I downloaded Release Preview and installed it. I have a problem when I shut down the computer. After I press windows key + I Power Shut Down, a box pops up titled "Winlogon.exe - No Disk. Then under that is the message "There is no disk in the drive. Please insert a disk into Drive G". After hitting the retry button a couple of different times the screen finally goes dark. When I was going to turn it back on, I noticed the Power Button was still list. The only way to do a complete Shutdown is to hold in the power button directly. How do I fix this problem?

• Prevent Outlook from automatically deleting meeting emails

  - by Wavy Crab

  I'm using Outlook Web Access to read my email. When I receive a meeting notice and acknowledge it, Outlook adds it to my calendar then deletes the email. Is there a way to disable Outlook automatically deleting the meeting email? There doesn't seem to be any way to configure this in Options - Messaging and Options - Calendar. Note that I'm using Outlook Web Access and not the desktop client. From the copyright date this appears to be Outlook 2007. Follow-up: Based on edusysadmin's comment I logged-in using IE8, which exposed a setting not available in Firefox - "Move out-of-date meeting requests and responses to the Deleted Items folder". However unchecking this box doesn't seem to impact the auto-delete behavior. Follow-up 2: Keep in mind I am using Outlook Web Access via a web browser. I do not have the thick client Outlook installed.

• Website Upgrade - Avoid Downtime

  - by nolan.sipos

  I have been requested to investigate how I can reduce the downtime of our website upgrades. We maintain a DNN site with both public facing pages and member only pages. The member only pages are directly linked to our core application database while the public pages are not. Our current process is to redirect website users as soon as the upgrade process begins, which includes Backup of the Prod DB Update Prod DB Update Executables (Application) Upgrade Website Application (If this requires an update) Install Dependencies Upgrade sub systems like communication engine and payment broker Update various configuration files Perform testing of systems Restart all services Allow access to site This process can take from 2 to 8 hours depending on upgrade required, scripts to be run, size of database and number or portals. My initial thoughts are to restrict users to read only pages and any update pages would be unavailable. Could anyone please offer suggestions as to the best practices for what I would think to be a common problem so that we can reduce this down time and if we need infrastructure changes, I can put this to our technical department.

• Unable to find a disable button for pop-up bubbles in 2.8.0.851

  - by Greg Richards

  I'm still using 2.8.0.722 on my Mac while a friend has upgraded to 2.8.0.851 The newer version on her computer has pop-up bubbles for every chat message when the chat window is minimized. Neither of us are able to find where to disable this feature. The difficulty arises when we minimize a chat window, but the bubbles continue to show everything the other person is typing, even when one of our kids is with us for a moment looking at something else on the screen. We have checked all throughout the Preferences settings, most notably the privacy and chat areas, to no avail. Ultimately we would like to disable these chat pop-up bubbles so that when a chat window is minimized, that conversation and all incoming messages will remain private until we restore that chat box to be viewable on the screen again. Thanks! Greg
