• Installed IE8 & SP3 on XP now I can't HTTPS from any browser.

  - by Kevin

  The computer is Windows XP Professional SP3 with IE8. On the Tools Options Connections the "Settings" is GRAYED OUT (I am an admin on the machine) Any browsing of https:// addresses results in IE displaying the following: "this program cannot display the web page" After installing an alternate browser and trying the same https:// address I get a similar error message. I have tried using Compatibility View Settings to for all web pages and this has no effect on the problem. HTTP addresses work fine, I can PING sites such as google.com without issue. Question: What could be preventing me from getting at the settings to check to see if I'm using a proxy? What else could be preventing HTTPS access?

• Gitosis installation of public key not working...

  - by user29600

  I've been following this tutorial to install and setup git on Ubuntu Server 10.04 using Windows 7 as a client. However, after finally figuring out how it works (executed gitosis-init a bunch of times on the wrong key), I copied the id_rsa.pub file over to the server in /tmp folder and ran it again. Unfortunately it still doesn't work and when I execute git clone [email protected]:gitosis-admin.git it asks for gitosis's password rather than the RSA Passphrase. I'm assuming is the same problem this guy is having here... however, after following his instructions: Purge git-core and gitosis and manually remove the /srv/gitosis folder and following the instructions again (with the proper id_rsa.pub file this time), I'm still having the same issue. Anyone know what I'm doing wrong? Is there any way to probe for more information that might help in solving this?

• Remote desktop pressing Windows key randomly

  - by wikiti

  When I'm using remote desktop at work from one specific PC it has a quirk which is really quite irritating. I'll be typing away and suddenly the Windows key will be pressed, things start minimising, explorer launches, workstation gets locked (but it locks the remote workstation, so I have that wallpaper in the background, rather than the wallpaper from the local machine as I would expect). I've swapped keyboards, even though it didn't seem to be related to hardware and it made no difference. Done some internet digging and found someone saying it's related to using windows-l to lock the workstation. I've tried to stop myself using that shortcut to see if it helps and have failed miserably :D It's happening to at least one other user remote desktopping from the same machine to a different PC. Reinstalling isn't really an option (I don't admin the PC or I would have tried it, grr), although I could probably get it done if it would definitely resolve the problem. Any ideas?

• Windows 7 is blocking ports

  - by Caleb1994

  I am trying to open port 80 and 3690 for HTTP and svnserve respectively. I have Windows Firewall off, and have tried temporarily disabling Mcafee VirusScan Enterprise, to no avail. According to http://www.yougetsignal.com/tools/open-ports/, both ports 80 and 3690 are still blocked. I can't think of what would be blocking them if Windows Firewall and my antivirus are disabled. Here is the output of netsh firewall show state Firewall status: ------------------------------------------------------------------- Profile = Standard Operational mode = Disable Exception mode = Enable Multicast/broadcast response mode = Enable Notification mode = Enable Group policy version = Windows Firewall Remote admin mode = Disable Ports currently open on all network interfaces: Port Protocol Version Program ------------------------------------------------------------------- 3690 TCP Any (null) 22 TCP Any (null) 80 TCP Any (null) 1900 UDP Any (null) 2869 TCP Any (null) Any help? I'm not sure what each item on the list of enabled/disabled items is, but "Operational Mode" is disabled, so I assume that one refers to me disabling Windows Firewall. I know that since Windows Firewall is off, this output might not be useful, but I figured I'd include it just in case, haha.

• Updating wordpress in a multi-node environment

  - by Peter

  I'm finding this very tricky in a multi node environment, with code under revision control. AKA. multiple frontends and single database. I have a deployment process that pushes a git repo to the servers, but obviously if I update Wordpress from within the admin panel, it will update the files to one FE. Then I would need to copy over the new files to the other FE nodes. Plus, whenever these changes are written when Wordpress updates on a node, it writes code into the git repo. As such, it then breaks the auto deploys that perform 'git pulls', as it then has untracked changes and refuses to pull in new deploys unless manually intervened. How does one easily keep Wordpress updated in a multi node (load balanced) environment?

• How to login without entering username and password

  - by torbengb

  I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious. I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users. Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways? (I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password. Yes, you're right. But that's not what this question is about. Thanks.)

• Question about Radio button/PHP/MySQL

  - by Marcelo

  Hi, I'm an engineering student and I'm developing a simple software based on HTML, PHP and mysql. I learned this topics on w3schools. I know only the basics. I tried to search about this in this website but I found questions about PHP, MySQL and HTML radio buttons which were much more complex than I need and that I could understand. Sorry for the English. (Q1) Ex: $email=$_REQUEST['email'] , in this case the input is text, if it where like a radio button for ex: sex: male or female, how would it be? (Q2) what would be the type of this field (for exemple sex in question 1) in the database: text, int, varchar ? Thanks for the attention

• Using a Dell PowerConnect to set up load balancing/redundancy, 1 switch 2 routres 2 private wan link

  - by MarianoC

  Hi, We have different locations connected by two different WAN providers. Each site has a dell powerConnect 6224 and two cisco routers with the WAN connections (we don’t have access to router admin). The 6224 connects to each cisco LAN port and to our LAN backbone. We would like the 6224 provide the ip gateway address and load balance and support redundancy, if one of the routes fail. Is this possible?. We can't find any samples on doing this and we have tried with no success. Any help or link to documentation regarding this, will be greatly appreciated. Thanks, MarianoC

• How is it possible to list all folders that a particular user/group has permissions on?

  - by Lord Torgamus

  Is it possible to list all folders/files that a given group has explicit permissions on, for a machine running Windows Server 2003? If so, how? It would be nice to see inherited permissions as well, but I could do with just explicit permissions. A little background: I'm trying to update groups/permissions on a test server. One of the groups, Devs, wasn't implemented correctly when it was created, and my goal is to remove it from the system. It has been replaced by LeadDevelopers, which has permissions on many — but naturally not all — of the same folders. I want to make sure that I don't accidentally orphan any folders or cause any other issues when I remove Devs. It did have some admin-level permissions.

• Cached css/javascript files on Sun Java System Web Server

  - by Derp

  I'm doing front-end web development in a Solaris 10 / Sun Java System Web Server 7.0U2 environment. I have noticed that changes to static css or javascript files often do not take effect immediately, whereas changes to static html files always do. My best guess is that a default setting in the web server causes it to cache certain file types in order to provide reasonable performance out of the box. I don't have the admin server running--I'll need to edit the config files by hand. What change(s) can I make so that all of my css and javascript edits take effect immediately? Thanks!

• How can I make VNC faster?

  - by NickAldwin

  I need to remotely access and use my work computer a few times a week. I want to use VNC because of the price. I've used VNC before, mostly on my own network, where it's fast. However, VNC over the internet is incredibly slow. Even at 256 colors and lower, with Aero turned off, it is unbearably slow. I recently used Ammyy Admin to connect to do something requiring a quick reaction time. Ammyy was really fast, with almost no lag, and it was running in full color with Aero on! How can I make VNC faster, like Ammyy is? I'd use Ammyy, but I would probably run into the 15hr/month limit pretty quickly. Any suggestions? [EDIT] I'm currently using UltraVNC.

• Can't change read only folder in windows 7

  - by James Drinkard

  I'm trying to run a Spring MVC 2.5 tutorial and when I run the ant script for a deploy, I get this error: deploy: [copy] Copying 2 files to C:\apache-tomcat-7.0.8\webapps\c:\projects\workspace\springapp BUILD FAILED C:\projects\workspace\springapp\build.xml:46: Failed to copy C:\projects\workspace\springapp\war\WEB-INF\web.xml to C:\apache-tomcat-7.0.8\webapps\c:\projects\workspace\springapp\WEB-INF\web.xml due to failed to create the parent directory for C:\apache-tomcat-7.0.8\webapps\c:\projects\workspace\springapp\WEB-INF\web.xml After reviewing the directory: springapp I saw the properties as read-only. No problem I thought as I'm logging in as administrator. However, changing the uac settings, going to a command prompt as admin and then trying to change the properties of the folder with attrib, making me the owner of the folder, changing the security settings etc... did nothing. I can't seem to change this folder to anything. So my question is, how do I change the settings on that folder so ANT can make changes to that folder?

• linux intrusion detection software

  - by Sam Hammamy

  I have an Ubuntu VPS that I use for practice and deploying prototypes as I am a python developer. I recently started teaching my self sys admin tasks, like installing OpenLDAP. I happened to turn off the ufw firewall for just a minute, and when I ran an netstat command, I saw a foreign ip connected to ssh that I traced to china. I'd like to know a few things: 1) Is there any good network intrusion detection software, such that if any IP that's outside a specific range connects to the VPN, I can be notified? -- I am thinking about scripting this, but I'm pretty sure there's something useful out there and I believe in the wisdom of crowds. 2) How did this person gain access to my server? Is it because my firewall was down? Or is it because they browsed my LDAP directory and from there figured out a way to connect (there was a clear text password in the tree but it wasn't one used by the server's sshd)?

• How to show what proxies/firewalls are enabled on Windows XP?

  - by Stephen Melrose

  Hi, I'm trying to fix a Windows XP PC that is having a strange problem. The computer can't seem to connect to the internet, even though an internet connection is present. The router and internet is working fine as I've connected a laptop to it via LAN and wireless and both worked fine. The PC in question is connected to the router as it has an IP from the DHCP. The problem is I can't connect to nor ping any internet address from the PC. I can't even connect to the router admin itself. I've tried both LAN ports in the PC, same problem and both. I'm assuming there's a proxy or firewall on the PC stopping the connections, I just don't know how to find them or see which one is causing the issue. So my question is how do I on Windows XP display the system proxy settings and/or any firewalls that are running? Cheers.

• OpenGL ES 2.0 Rendering with a Texture

  - by Kyle

  The iPhone SDK has an example of using ES 2.0 with a set of (Vertex & Fragment) GLSL shaders to render a varying colored box. Is there an example out there on how to render a simple texture using this API? I basically want to take a quad, and draw a texture onto it. The old ES 1.1 API's don't work at all anymore, so I'm needing a bit of help getting started. Most shader references talk mainly about advanced shading topics, but I'm really unsure about how to tell the shader to use the bound texture, and how to reference the UV's. Thanks!

• reinstall PHP as apache module

  - by Ewan

  Hi sorry for the newbie question, I am not a sys admin by any means. I recently set up a VPS with webmin/virtualmin. Our CMS of choice says that PHP needs to be run as an Apache module in order to run. It says: Recompile PHP with the flag --with-apxs I've googled but can't find how to do this particularly. I think I installed PHP using "yum install php" or thru webmin, but can't remember exactly. Appreciate if anyone can point me in the right direction.

• ssh into my mac from my ipod

  - by mechko

  Ok so this is what I got, but it don't look right... The set up is as follows: My Mac is on a wireless network, presumably behind a firewall over which I have no admin privileges. Further, said wireless network changes my internal IP randomly at random times, so I do not know what my ip is. Note that localhost is a variable ip I forward some port or the other to my dns: ssh -R 19999:localhost:22 sourceuser@remotehost connect to my remotehost from my machine: ssh sourceuser@remotehost and then connect to the port I forwarded: ssh localhost -p 19999 [solved] Second question, there are a bunch of ssh clients for the iphone. Which one should I use? EDIT: Since jailbreak is not illegal, simply frowned upon by the Corporation, I've decided to go with that. I have a nice shell with openssh and the works. Best of all, it's free and it does exactly what you expect.

• Sendmail Undeliverable Redirection?

  - by Dizzle

  Good afternoon; I don't know much about sendmail, so this may be fairly easy for those of you more experienced with it. We have an account, "[email protected]", sending reports to various groups. From time to time an undeliverable message will be sent back to "[email protected]". We'd like for those undeliverable messages to be rerouted, or bounced, from "[email protected]" to a group of our choosing. To carve out a scenario for clarity: [email protected] sends a report to [email protected] and [email protected] [email protected] has someone who's mail account no longer exists, triggering an undeliverable message being sent back to [email protected] Rather than having the undeliverable message sit in [email protected]'s Inbox, we'd like for it to be automatically rerouted/bounced to an admin group, [email protected] So I guess a "rule" of sorts. I've come across this solution: Sendmail : ignore local delivery But I don't know enough about sendmail to know if this is what will fit this situation. Any help is greatly appreciated.

• Windows 7 migration: How to move application settings?

  - by FrustratedWithFormsDesigner

  Migrating from WindowsXP Home to Windows 7 Pro. The last bit that I'm stuck on is migrating application settings, such as the settings for Opera, Firefox, MSN Messenger, and others. On the XP system, this all seems to be in "user/Local Settings" and "user/Application Data". On the Windos 7 system, there is a "user/AppData" folder as well as "user/Application Data" and "user/Local Settings". When I try to access "Application Data" and "Local Settings" on Windows 7, I get an "Access Denied" error (even though my user is an admin). So... if I can't copy my application settings files to "Application Data" and "Local Settings" on Windows 7, where to I copy them to?

• Can not join comp to the domain... greyed out

  - by Logman

  I have an old WinXP Pro SP3 computer I need to join to the domain, simple right? not really. When I go to control panel - system - computer name and click on CHANGE ("rename this computer") everything is greyed out. I can not set it from workgroup to a domain. I am logged on locally as an admin. (Builtin account and one I created) I have checked local policy (gpedit.msc) on the comp, but it feels like a needle in the haystack. I could probably reload an image faster than trying to fix this...but I am curious so I post here to see if anyone knows of it/fix. I tried reseting the policy to defaults, but no luck: secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose EDIT:

• Download or view a servers wins database

  - by Segfault

  I am trying to troubleshoot a WINS browsing problem in a Server 2008 AD Forest. I am in one domain and the problem is with a sibling domain. What command can i use to dump or view the WINS database on a particular AD server by name, in a different domain than me? I thought one of the subcommands of net would have an option for this, but I can't find it. I also tried browstat.exe getblist but it gives me an error message "The list of servers for this workgroup is not currently available". I am not a domain admin and don't have any rights to the either domain other than a normal user. Anyone know how this can be done?

• Windows Shell Programming book suggestion

  - by Lijo

  Hi, I am a web developer using C#. I would like to experiment with Windows shell programming in C#. Many people suggests that using managed applications for shell program, is dangerous. (Creation of separate instances for each process versus in process shell. Also version dependency) Frankly speaking, I am totally new to shell. Is there a book available, that will treat these topics; both through managed code and unmanaged code (but mostly towards managed code)? It would be great if that book is concise , for beginner and giving theoretical background of the shell. Please suggest…. Thanks Lijo
