• Set up ad hoc wireless connection between Windows Vista and Mac OS X

  - by Skarab

  I have the following problem - Windows Vista does not connect to adhoc wireless network created on my Macbook. I have tried to create secured (with 40 bit key) and unsecured network but Windows Vista still has problems to connect. Windows VISTA informs me -- after 5 minutes of attempts - that setting up the connection -- with my adhoc network -- took too much time. My question: do I need to configure some settings on Vista to connect it to my Macbook? Maybe it is a problem with DHCP? Edited: I have tried the other way: http://superuser.com/questions/202890/set-up-an-adhoc-network-in-windows-vista-to-connect-to-and-share-the-internet-con

• How restore back up email files in qmail

  - by Maysam

  I have problem with restoring some old backup mail files in a mail server that uses qmail. The problem is, when I copy a new email file to the /cur directory, the number of emails in front of inbox increases, but when I click on the inbox, I don't see the newly copied email. I can only see the old emails. I also deleted maildirsize and courierimapuiddb files and they where automatically created again, but it didn't help and I cannot still see the email in my inbox. Is there something I am missing? How can I restore the backed up email files? Please note that when I copy the email files in /.sent-mail/cur directory, they are all displayed in my sent box, but that doesn't happen for inbox files in /cur directory.

• Windows 7 won't restart with SSD

  - by JL

  I have this annoying problem that I just can't seem to fix. Recently I upgraded my main boot drive to an OCZ Vertex Turbo (60GB) which is an SSD. I've installed Windows 7 64bit. The drive works, and is really quick... blah blah blah. My problem is when I do a restart, for example click start, then arrow next to shutdown, and restart. The computer will shut down, and do a warm reboot, but it gets stuck where it says loading Windows. Just before the animation starts. So what I have to do is physically press the reset switch on the computer, then it restarts, firing up a menu which offers to launch Windows Startup Repair, so I select "Start Windows Normally". After this I boot in normally, but its damn annoying. Any ideas why this is happening, what I can do to fix it?

• How to open first n bytes of file in hexadecimal and edit it?

  - by Larssend

  I want to edit some .avi videos (cut them, to be precise) in VirtualDub but it failed to open the files. They are encoded in xvid, which I have installed, and play in KMPlayer without problem. Also, all other xvid videos can be opened and cut just fine by VirtualDub. I suspect there's something wrong in the first few bytes of these particular videos (the magic number?). This means I have to open the offending files in a hex editor and make some necessary adjustments to the header. Problem is, they are very large ( 3 GB each) and take very long time to open in UltraEdit. Can UltraEdit open just the first few bytes of a file? If not, do you know of an application that can do that? Edit: I'm using Windows XP.

• Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not am not a "handsome prince"!

  - by Jim Dobbs

  Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

• Flash video for Windows/VirtualDub/media player

  - by acidzombie24

  I don't want to install any codec packs because I remember the last time I did it unwanted results occurred. (I think a codec didn't play nice with an application and was a known problem with the codec. I think). I would like to open up Flash videos (.flv) in VirtualDub. I have a plugin for VirtualDub I just need the codec now. I tried putting DLLs into the VirtualDub folder but that didn't solve the problem. How can I get a codec for VirtualDub to use to decompress Flash video files?

• UFW: force traffic thru OpenVPN tunnel / do not leak any traffic

  - by hotzen

  I have VPN access using OpenVPN and try to create a safe machine that does not leak traffic over non-VPN interfaces. Using the firewall UFW I try to achieve the following: Allow Access from LAN to the machine's web-interface Otherwise only allow Traffic on tun0 (OpenVPN-Tunnel interface when established) Reject (or forward?) any traffic over other interfaces Currently I am using the following rules (sudo ufw status): To Action From -- ------ ---- 192.168.42.11 9999/tcp ALLOW Anywhere # allow web-interface Anywhere on tun0 ALLOW Anywhere # out only thru tun0 Anywhere ALLOW OUT Anywhere on tun0 # in only thru tun0 My problem is that the machine is initially not able to establish the OpenVPN-connection since only tun0 is allowed, which is not yet established (chicken-egg-problem) How do I allow creating the OpenVPN connection and from this point onward force every single packet to go thru the VPN-tunnel?

• PostgreSQL under Mac OSX Lion. Wrong userpass?

  - by Matt

  I'm completely helpless, maybe you guys can help me out. I installed PostgreSQL under my new MacOSX Lion. When I try to connect to my localhost with pgAdminIII.app it says: Error connecting to the database: FATAL password authentication failed for user postgres I just have no idea what to do? Non of my passwords work. Neither my adminpass nor "postgres" nor anyhting else. I tried to install it again via the console where I found this helpful link: http://www.peerassembly.com/2011/08/...resql-on-lion/ However the problem is, that when I try to run createuser -a -d _postgres the same password problem appears again. I just can't seem to find a solution to this. Always wrong password. Btw. I have a new User called "PostgreSQL" on my machine after I installed postgres. Any ideas? I'm so stuck and I really need to make this work.

• Data drive disappearing.

  - by Mike Keller

  We have a Windows 2003 R2 server with SP 2 here that randomly loses a partition. There are two partitions the C: and the D: (the one that disappears). When I go into Disk Management the space shows available on the drive but that it isn't formated. There are two drives that are set up in a RAID 1 array. There isn't anything sticking out in the event log as to something triggering this problem and thank god we do daily backups of the data, but it gets kind of annoying to have to go back in there and reformat the partition and restore the data. Any places I can poke around to find the cause of this or even better solutions to the problem would be appreciated.

• Partitioning a bootable Flash drive

  - by mmc

  Is it possible to have a 2 partition Flash drive that looks like the following: A partition that is bootable to OS X (this will require a GUID partition table) A second partition formatted either FAT32 or NTFS that is readable on both OS X and various flavors of Windows I have set up a disk using Disk Utility on the Mac, and it boots fine with a second FAT32 partition... but Windows does not see it. Any flavor of Windows wants to format the entire drive. Has anyone done this, and if so, can you explain the steps you followed? EDIT: Making it bootable is no problem. I have that. I'm wondering how to make the second partition on a Flash drive visible to Windows. It's possible that the "second partition" is the problem, and I need Windows to be first, and HFS to be second. I'll try that tonight.

• ORA-01019 error only as an administrator

  - by Mike

  I'm having a strange problem. I've installed the Oracle 10g client on a terminal server running Windows Server 2008R2. When I try to connect to Oracle, using, say, Toad, I receive the error "ORA-01019 unable to allocate memory in the user side". But this only happens if I'm logged in as an administrator. If I connect as a normal user, I can connect without issue. Also -- if a normal user is connected, I can then connect without a problem as an administrator. Any thoughts?

• Boot Camp fails to create a Windows partition because it can't move files

  - by Jens Bannmann

  I'm running Mac OS X 10.6 (Snow Leopard) on a mac with a 320 GB drive, 167GB free space, and I can't get Boot Camp running. The wizard starts creating the Windows partition, but fails with a message claiming it cannot move some files. The message suggests to back up my hard disk, reformat it, restore my files, and re-run Boot Camp wizard. The problem is: Though I do have backups (Time Machine), I don't feel like formatting my hard disk right now :-) I found a thread in some forum discussing this problem. The suggestion was to defragment my volume with iDefrag, and lots of people claimed that solved the issue. So I went ahead and got iDefrag 1.7.1, created a bootable DVD and chose the "compact" setting recommended before partitioning - but still no luck with Boot Camp! So how do I get this working? Fun note: last year, I briefly set up Boot Camp with 10.5, and it worked perfectly. Probably I did not use that much hard disk space back then...

• Limited connection whenever I connect to a Wi-Fi network outside the company

  - by anderZubi

  Whenever I connect my work laptop to a wireless network outside of my company, the connection shows as Limited, and there is no internet access. I have tried several times by disabling/enabling the network adapter, restarting the computer... without success. Sometimes, after a while, without taking any action, it shows fine, and I have internet access. But can pass 2 hours before this happens. My computer is under a domain network, but I don't think that's the problem, because I can successfuly connect other computers belonging to same domain to other networks. I'm running Windows 8 Pro and my network adapter is the following: Qualcomm Atheros AR9285 Wireless Network Adapter Any idea of which is the problem and how to solve it?

• Working bootable CD now suddenly freezes at starting point

  - by xolstice

  I have this strange problem with a bootable CD I created that uses floppy disk 1.44MB emulation. The PC originally worked with it just fine and booted from the CD several times from the prior occasions I used it. Now for some strange reason it decides to freeze at the point where it displays the following text on the screen and does not proceed further: Boot from ATAPI CD-ROM 1. FD 1.44MB System Type-(00) The other strange thing is that if I put in a Linux bootable installation CD, it boots that without any issues. Everytime I stick this custom made bootable CD in it pulls this freezing act. Has anyone experienced this or know how to correct the problem?

• Not all events appear in Nagios history (archive)

  - by Lars

  in the "Host & Service history" of my check_mk interface I can see various events, but a lot of events are missing. On the default interface at "View Alert History For This Service" or in the logfiles /var/log/nagios/archives/*.log the same issue: I can see many events of the last days, but not all of them. In the /etc/nagios/nagios.cfg the options log_event_handlers, log_initial_status and log_passive_checks are set to 0, the other log_... options are set to 1. I don't think that any of these options causing the problem that not all events are logged. What could cause this problem?

• ICQ offline messages (do not show up)

  - by Nils Riedemann

  Hi there, I have a weird problem with offline messages: I use Adium on 2 Macs (home and office) and Beejive (iPhone) for connecting to ICQ and other protocols. When someone sends me an offline messages I expect them to show up the next time I login with any of my 3 devices. But thats not the case. Recently some show up at the office, some at home and some on my iPhone – couldnt figure out any logic behind it, seems rather random. I thought for a while that it depends on the last device i have been logged in with. But thats not the case either. A friend can send me offline Messages during the weekend, i can login with my Mac at home or iPhone, yet in some cases it only shows up when logging in from office. Weird. It really freaks me out – and no, i can't make 'em go to jabber or the like. Anyone experiencing a similar problem?

• Windows Server Task Scheduler: Running scheduled executable fail-safe?

  - by Mikael Koskinen

  I have an executable which I've scheduled to run once in every five minutes (using Window's built-in Task Scheduler). It's crucial that this executable is run because it updates few time critical files. But how can I react if the virtual server running the executable goes down? At no point there shouldn't be more than 15 minutes break between the runs. As I'm using Windows Server and its Task Scheduler, I wonder is it possible to create some kind of a cluster which automatically handles the situation? The problem is that the server in question is running on Windows Azure and I don't think I can create actual clusters using the virtual machines. If the problem can be solved using a 3rd party tool, that's OK too. To generalize the question a little bit: How to make sure that an executable is run once in every 5 minutes, even if there might be server failures?

• Fax in Small Business Server 2003 fails to hang up

  - by Tim Anderson

  We have a problem with fax in SBS 2003. External modem, Courier v Everything which is a recommended model. It receives a fax OK, but then sometimes (quite often) fails to hang up. Attempts to send faxes thereafter get an engaged tone. The only fix when this happens is to reset the fax modem. Even restarting the server is not enough. We've tried with a different model modem, same problem. Any ideas? Tim

• How can we control the device driver load order in Windows XP ?

  - by Deniz

  We are trying to install both an HP scanner and a Kodak scanner on an XP machine and the problem is that that HP's scanner driver always places itself into the first and default scanner device position. We are using an automation software on that machine which must use the Kodak scanner as the default scanner. The HP flatbed isn't needed to be the default scanner on that machine. It will always be used manually and through its own software. Our developers did some research 2 years ago couldn't find a solution. Nowadays we are preparing to expand our user base and this problem did surface again on machines with the same configuration. I did a more aggresive search pn the net and found some tips like this one : http://support.microsoft.com/kb/115486 I couldn't realize how to suit this solution to my scenario. Could someone please point me to the right direction ?

• Win7 OpenSSH config: no address associated with name

  - by Jonah

  I am using OpenSSH on win7. My home dir is C:\Users\JG, and inside that dir I have the file C:\Users\JG\.ssh\config, with these contents: Host <redacted server ip here> HostName digitalocean_git User git IdentityFile ~/.ssh/digitalocean_moocho/id_rsa The id file pointed to by the "IdentityFile" entry works, as I use it just fine via putty, but for this problem I am trying to get command line OpenSSH working. The crux of the problem is explained by this output: >ssh -v digitalocean_git OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 debug1: Reading configuration data /c/Users/JG/.ssh/config ssh: digitalocean_git: no address associated with name Why is no address associated with the name?
