• Can't get nmap to work under Windows 7 64 bit

  - by jitbit

  I'm trying to install and run the nmap tool to test my server, but it keeps saying Note: Host seems down. If it is really up, but blocking our ping probes, try -P0 and showing all the server ports are closed. Which is not true - the server is up and has lots of open ports. Any ideas? UPDATE: Just to clarify - the server can be pinged and port-scanned fine by other programs. It's juts nmap that does not work. Even "google.com" seems to be down for nmap.

• Creating encrypted database for work

  - by Baldur

  My boss posed this problem to me: Encrypted: We need an encrypted database for miscellanious passwords we use at work that are currently only in people's head. Easily accessable: Someone needs to be able to quickly access specific passwords, possibly at hectic moments. This requires any sort of public key management (keeping it on a USB key in a sealed envelope?) to be relatively easy. Access control: The system should have groups of passwords where only specific people have access to specific groups. Recoverability: We need to make sure passwords from one group aren't lost even if the only users with direct access quit or pass away—hence we need some way where (for example) any two members of senior management may override the system (see the treshold link below) and retrieve all the passwords with their key. The first thing that jumped into my mind was some form of threshold and asymmetric cryptography but I don't want to reinvent the wheel, are there any solutions for this? Any software should preferrably be free and open-source.

• MS Clear Screen Saver doesn't work

  - by ufoq

  I have a problem with really exotic thing - Microsoft Clear Screen Saver. As it's name suggests, it's a screen saver, that's transparent (MS posted it as a part of W2k Resource Kit). When you move the mouse/hit a key, the "lock" dialog appears. I would like to use this to view servers desktops without need to log in. I tested it on my XP's, and it works flawlessy. But on W2K3 servers it doesn't work. After the screensaver timeout, the error message is displayed: "The Clear Screen Saver cannot display the user desktop after the workstation has been locked"

• Portable Display doesn't work anymore

  - by RipCord

  My USB portable monitor will not work since I installed the hard drive onto an HP laptop. I have installed all the new hardware drivers and do not have any more device issues in device manager view. My old laptop was a lenovo. The new one is an HP. The system seems to recognize devices that I connect via, usb but the portable display still does not show anything on the screen. It is probably a conflict in the registry but I'm not sure how to find it and the Power User does not have the luxury of letting me troubleshoot for hours to isolate the problem.

• How to explain DRM cannot work?

  - by jerryjvl

  I am looking for the shortest comprehensive way to explain to people that are trying to use DRM as a technology to prevent users from using their data in some fashion deemed undesirable, why their solution cannot work by definition. Ideally I'd like something that: Covers why technically it is impossible to have people access local data, but only in such-and-such a way Imparts an understanding of why this is, to avoid follow-on "But what if" rebuttals Is intuitive enough and short enough that even a politician (j/k) could grasp it When faced with this situation I try to be clear and concise, but I usually end up failing at least on one of these points. I'd really like to have a 'stock' answer that I can use in the future.

• How do quotes/strings work in Powershell?

  - by Casey

  I'm have a command line that works in the regular old Windows Command Shell, but somehow gets misinterpreted in Powershell (I'm fairly new to Powershell). sqlcmd -S .\SQLEXPRESS -i "f:\SQLBackups\ExpressMaint.sql" -v DB="ksuite" -v OPTYPE="DB" -v BACKUPFOLDER="f:\SQLBackups" -v REPORTFOLDER="f:\SQLBackups\Reports" -v DBRETAINUNIT="days" -v DBRETAINVAL="7" Powershell seems to be stripping the drive letters out of the arguments that require paths. For example, I get the following when I attempt to run the above command in Powershell: Sqlcmd: ':\SQLBackups': Invalid argument. Enter '-?' for help. Well sure it's invalid without the drive letter. I have tried variations on double quoting it, escaping it, etc. but can't get it to work. What am I missing that Powershell does differently?

• How to work around Windows error 8x90070057?

  - by Chris

  So today I was trying to copy a simple .PDF file from a local folder on my machine to a network folder and every time I tried to move the file I would get an error dialog box which would state that I was passing a wrong parameter and give me the error code of 8x90070057. Does anyone know of a way to work around this error so that I can get this file copied? I have tried renaming the file with an underscore in front. I have tried copying from my local folder to my desktop and then to the remote folder. I have tried hunting down anything that might be using the file. An example of the file name is: Flowers & Trees.pdf

• CentOS 6 init script doesn't work properly

  - by user711643

  I'm setting up my ruby production server based on CentOS 6. I need a process called god (which is a process monitoring tool) to start at boot. I'm using an init script that I found here. Just as stated in the guide I ran: chkconfig --add god and then chkconfig --level 345 god on After this if I run "service god start|restart" everything works. It loads the available configurations and brings up the related processes (if they are not running). Problem is it doesn't work at boot. If I reboot the system, then I do "ps -aux | grep god". At this point "god" is running but apparently it didn't load the configuration files. If i run again service god restart, it loads everything without problems. What am I doing wrong?

• USB Mouse doesn't work after turning on Laptop

  - by Barry

  I have a USB mouse attached to my laptop which does not work when I switch my laptop on. I have to unplug it and plug it back in before it works. When I do this no driver installation occurs (presumably because it has already done this) the usual beep sound does occur and the mouse starts working again. If my laptop goes to sleep I can move the mouse and the laptop comes back to life. In fact it works perfectly apart from this annoying niggle on startup. Can anyone shed any light as to why I have to keep unplugging and plugging my mouse back on startup? I am running Windows 7 Home Premium Service Pack 1 (64 bit) on a Toshiba Satellite L755-1LL Laptop.

• Shutdown button doesn't work in Windows 8

  - by Yob

  Some time ago I installed Windows 8 64bit ready-to-market version (as a student I had access to it before premiere). What I discovered is that the "shutdown" button doesn't work. When I want to shutdown the computer it simply logs me out. In order to turn off my machine I have to click "restart" and then simply press the poweroff button. I installed some updates but this issue is still not resolved. Is there any way to shutdown the computer in a normal way?

• Block Websites at Work

  - by user791022

  At work there are about 40 PCs. I want to block all the websites and only allow a few Domains/Websites for operators. A few operators can access anything. I want something quick and easy so I can filter the Block/Allow websites for all computers from one main computer, like a server or something. Windows Vista Home and Windows 7 Home are installed on the PCs. Is there any software can do this? PS: Please don't answer about Microsoft Windows Server OS..

• Custom prompt doesn't work on Mac Terminal

  - by mareks

  I like to use a custom prompt (current path in blue) on my unix machine: export PS1='\[\e[0;34m\]\w \$\[\e[m\] ' But when I try to use it on Mac's terminal it doesn't work: it fails to detect the end of the prompt and overwrites the prompt when I type commands. This also happens when I'm inputting a long command where it wraps over the same line instead of starting a new line. I don't understand why this is the case since I use bash on both machines. Any suggestions on how to remedy this?

• Is there a way to save "work sessions" in linux

  - by mike

  I regularly work on different projects, using different software. For project 1 I need to open for ex : Filezilla, Gedit and Nautilus (set to a specific folder) For project 2 I need to open foz ex : Gimp, Nautilus (set to another specific folder) etc. What I would like is a kind of sessions manager, where I could create entries "project 1", "project 2", etc. And with one click or command, open all the softwares I need. Perhaps there's an easy way to write a batch file for this? Any idea is welcome :)

• Which handsets work with IP DECT base?

  - by waldrumpus

  My workplace uses an Ascom IP DECT base station (IPBS1), and Ascom handsets as well. We're looking to replace some broken handsets; the ones by Ascom, however, are rather expensive, and we're not altogether satisfied with their quality. I've been looking at handsets from other manufacturers, which are much less expensive - however, since I don't know anything about DECT, VOIP, etc, I don't know if they will work with the base. I've perused the base's manual, but found nothing on handset compatibility. How can I find out what kind of handset works with our base?

• curl makes a site work externally once run locally (apache)

  - by Kyle_at_NU

  Currently when I visit mysite.mydomain.com external to the local network I get in the browser: This is the default web page for this server. Nothing to see here. This is not even the "It Work's" Apache page. Then if locally (Apache2 on Ubuntu Server 12.04 with curl installed ) type: curl mysite.mydomain.com I get the site I expect. Then the next time i visit the page externally I get the correct site. Has anyone seen this before? Tips/Suggestions?

• SSH tunnel doesn't work

  - by s1ck

  I am trying to use my server as a "proxy" with ssh. However, setting up tunneling with ssh -D localhost:8000 user@myserver does not work. I tested this on various machines with ssh and putty - It connects just fine, but when I set my browser settings accordingly, I just get an error "Connection has been reset". I tried monitoring the traffic with wireshark, but I didn't even see some tunnel-traffic. I explicitly set AllowTcpForwarding to "yes" but I still can't use the tunnel. When running ssh in verbose mode, I don't get any errors but debug1: Connection to port 8000 forwarding to socks port 0 requested. debug1: channel 3: new [dynamic-tcpip] debug1: channel 3: free: dynamic-tcpip, nchannels 4 What am I doing wrong?

• Reset disk does not work for different model of computer

  - by dato

  I've created a reset USB disk on my HP computer, with Windows 7 Ultimate 32-bit, and it works fine. However, it does not work for Acer computers (notebooks too), so what is the problem here? I've have created it for the same user named user, and the password is exactly the same as well. Is it possible to show the language bar with a keyboard shortcut at the logon screen in Windows 7? I know I can do it through Control Panel, but I can't log into the system. When I click Reset Passwword, it shows me my USB flash drive and says that the password hint is on this USB drive. Then I click Next and type the new passwword, then confirm this new password, but an error dialog is shown. It says that an error occured when trying to change the password for this user-

• Remote Desktop from Mac to Windows (Microphone, Sounds must work)

  - by WebDevGuy

  I have a laptop that is running Windows 7. I want to remotely connect to it using my 27" iMac. I was using an app called "Jump Desktop" and I really like it. The only problem is that I cannot use Skype, GoToMeeting, etc... because the microphone doesn't work remotely. Any recommendations on other apps that support remote mic/sound? In other works I want to use solely my iMac, remote into my Windows 7 laptop, use skype, etc.... on the laptop. Thanks

• Setup of Citrix-Client (xenapp) doesn't work on Windows Vista Utimate

  - by Ice

  I have a notebook with a fully patched Vista Ultimate and there was a Citrix ica-client installed for access on our citrix-server(s). Once the client couldn't access the server – it took so much time ( 5 min) and everything froze. I did an uninstall und cleaned up the registry. But now it's not possible to reinstall a xenapp-client even the newest directly from www.citrix.com. What could be the reason? How to fix this issue? PS: At the moment I start a vm with an XP and the citrix-access runs like a charm, but that only could be a work-a-round.
