• Backup Permissions for an Active Directory Profile Directory

  - by Earls

  I have Folder Redirection turned on so the profiles are on a Windows shared folder on a File and Print Server... \folders\Profiles I want to back up the entire Profiles directory, but as Domain Admin I don't seem to have the privileges to "select all and copy" the entire directory structure. The user profile subfolders (Appdata, Documents, Desktop, Pictures, etc.) throw access denied errors... I tried to grant Domain Admins full privileges to the Profiles directory and thought the subfolders would inherit the privileges, but I get access denied errors just trying to set the permissions... How can I assign a user to the Profiles directory so that I can copy the entire directory tree to back it up?

• How to config DLink DSL-2640T to allow access from DynDNS route to specific port on my PC?

  - by Greendog

  Hi, everyone. I think you can help me out from this little problem. I am trying to setup an Apache web server on my PC and let the other remotes to this machine via DynDNS.com. I found that DLink DSL-2640T make me confuse about how to configure the routing from http://myhostname.dyndns.org:80 to 192.168.1.13:80. At the moment when I browse the URL http://myhostname.dyndns.org, it will lead me to router's admin control panel. Could you help me out by giving your guideline or suggestion?

• How do I set "MaxPermSize" for Atlassian Fisheye/Crucible running as service on Win2k3?

  - by Jeremy

  I have been trying to setup Atlassian Fisheye/Crucible as a service on Win 2K3 R2 for two weeks. I keep getting various "java.lang.OutOfMemoryError: PermGen space" errors, which crash Fisheye and force me to restart the service. I've followed the example on the Atlassian support site to configure MaxPermSize within the service wrapper. However, when I check SysInfo inside the Fisheye Admin pages and the debug log, I don't see any confirmation. The Java Heap info is in both places, so I'd expect the MaxPermSize setting to show up in both places. The error is persisting and Atlassian support has been little help. I appreciate any help.

• How to troubleshoot a remote wmi query/access failure?

  - by Roman

  Hi I'm using Powershell to query a remote computer in a domain for a wmi object, eg: "gwmi -computer test -class win32_bios". I get this error message: Value does not fall within the expected range Executing the query local under the same user works fine. It seems to happen on both windows 2003 and also 2008 systems. The user that runs the shell has admin rights on the local and remote server. I checked wmi and dcom permissions as far as I know how to do this, they seem to be the same on a server where it works, and another where it does not. I think it is not a network issue, all ports are open that are needed, and it also happens within the same subnet. When sniffing the traffic we see the following errors: RPC: c/o Alter Cont Resp: Call=0x2 Assoc Grp=0x4E4E Xmit=0x16D0 Recv=0x16D0 Warning: GssAPIMechanism is not found, either caused by not reassembled, conversation off or filtering. And an errormessage from Kerberos: Kerberos: KRB_ERROR - KDC_ERR_BADOPTION (13) The option code in the packet is 0x40830000 Any idea what I should look into?

• Cleaning Up Unused Users and Groups (Ubuntu 10.10 Server)

  - by PhpMyCoder

  Hello experts, I'm very much a beginner when it comes to Ubuntu and I've been learning the ropes by diving in and writing a (backend-language independent) web app framework that relies on apache, some clever mod_rewrites, Ubuntu permissions, groups, and users. One thing that really annoys my inner clean-freak is that there are loads of users and groups that are created when Ubuntu is installed that are never used (Or so I think). Since I'm just running a simple web app server, I would like to know: What users/groups can I remove? Since you'll probably ask for it...here's a list of all the users on my box (excluding the ones I know that I need): root daemon bin sys sync man lp mail uucp proxy backup list irc gnats nobody libuuid syslog And a list of all of the groups: root daemon bin sys adm tty disk lp mail uucp man proxy kmem dialout fax voice cdrom floppy tape sudo audio dip backup operator list irc src gnats shadow utmp video sasl plugdev users nogroup libuuid crontab syslog fuse mlocate ssl-cert lpadmin sambashare admin

• customErrors="RemoteOnly" not working properly in Server 2008

  - by Atomiton

  It would appear that on my brand new Windows Server 2008 with IIS7, customErrors is not working. We have customErrors set to RemoteOnly in the web.config on our Asp.Net sites and applications. However, no matter what we do, it would appear that our sites act like it's set to On and we can't get any detailed messages showing up on our applications when remoted into our servers. I'm not entirely sure how to trace where this is being overrided, or if there is something in the way the server is configured that would make the server think the request is internal? How does this actually resolve correctly, anyway? Any help is appreciated... Our network admin has added domains to our hosts file to direct applications to the IP address.

• centos: nginx + thin webserver, incoming connections not allowed

  - by cbrulak

  I setup a fresh CentOS 5 install, compile nginx from scratch and am using thin as the rails server. If I visit the ip adress on the LAN: (for example) 1.2.3.4 I get the website not found error. However, I can ssh into the machine. If I use links to visit the ip address, I get the landing page. Any suggestions? Thanks EDIT I ran system-config-securitylevel and then was able to change the security settings to allow incoming connections.

• Port forwarding (portmap) works only locally

  - by Tag Wint

  There are four hosts hostA winXP hostB Win2003 hostC Linux RHEL hostD Linux RHEL hostA cannot connect to C and D directly, but B can hostA connects to hostB using VPN hostB and hostC belong to the same subnet1 hostD is in subnet2 From hostA I need to connect to hostC and hostD by SSH. Now I can do it as follows: 1.connecting from hostA to hostB by RDP logon and there: 2.start putty client. I'd like to omit step 1 and connect from A to C and D directly On hostB I have admin acoount and configure port forwarding as follows: netsh interface portproxy add v4tov4 listenport=N1 connectaddress=hostC_IP connectport=N2 netsh interface portproxy add v4tov4 listenport=N3 connectaddress=hostD_IP connectport=N2 netsh interface portproxy show all: Listen on IPv4: Connect to IPv4: Address Port Address Port --------------- ---------- --------------- ---------- * N1 hostC_IP N2 * N3 hostD_IP N2 Now from hostB I can connect to either C and D: ssh localhost:N1 ssh localhost:N3 from hostA ssh hostB:N1 works too, but ssh hostB:N3 DON'T I guess the reason might be different subnets, still have no idea how to fix it. What should I do?

• What is /opt/sun_docs used for, in Solaris 10?

  - by benc

  Solaris 10, SPARC. While trying clean up my "/opt" directory, I saw the "sun_docs" directory. I scanned the contents with "du -a", and also found a single, possibly related file (/var/opt/sun_docs/sundocs.html). If I understand correctly, it looks like a local set of HTML files, designed to be ready by a locally running browser? It looks like it could be shared via http, if an admin knew how to turn that on. I did google and check docs.sun.com. -ben

• Server Configuration / Important Parameter for 500Req/Second

  - by Sparsh Gupta

  I am configuring a server to be used as nginx server for a very heavy traffic website. It is expected to receive traffic from a large number of IP addresses simultaneously. It is expected to get 500Req/Second with atleast 20Million unique IPs connecting it. One of the problems I noticed in my previos server was related to iptables / ipconntrack. I am not aware of this behaviour and would be glad to know which all parameters of a ubuntu / debian (32/64) bit machine should I tweek to get maximum performance from the server. I can put in a lot of RAM on the server but mission critical task is the response times. We ideally dont want any connection to be hanging / timing out / waiting and want as low as possible overall response times. P.S. We are also looking for a kick ass freelancer system admin who can help us figuring / setting this all up. Reach me incase you have some spare time and interested in working on some very heavy traffic website servers.

• How to deploy local project to Amazon

However, the tutorials I have found so far shows you how to setup your instance and stops there. So my question is, how do I get my local webapp onto my Amazon instance? FYI, I'm a sys admin/web dev. noob. Thanks.

• Proxy via Telnet

  - by Vreality2007

  I know telnet is insecure and all, but I'm stuck using it because ssh is blocked. I know how to setup ssh to bind the connection to a local port, is there a way to do this with telnet? For example, if I am using an ssh connection, I would bind it to port 999 like this: ssh -D 999 [email protected] -N -C I've tried using the -b command in linux, but to no avail. Is this even possible? This is what I've tried: telnet host.com -b 999 I'm sorry if the answer is obvious, but I've done a lot of research and testing and I can't seem to figure this out. NOTE: I plan on telling the admin if I can find a way to get this to work, this is based off of simple curiosity and not malicious intent. If I can't bind a telnet port, is there a way to tunnel an ssh connection through telnet?

• Sql Server 2005 cluster - unable to rename to old server name

  - by Paul2020

  We have a sql 2005 cluster on W2K8 cluster. It is a named instance say SRV1\A. Then I built a new W2K8 (with a diff cluster service name) but the same service account. Then I installed a new sql 2005 cluster say SRV2\A. Now when I bring down the sql server resources on SRV1 and try to rename SRV2\A to SRV1\A through the cluster admin, I get the error the network name already exists. I have tried bringing an old cluster and installing a new cluster with the same name and it works. Why am I not able to rename the name? Any advice would very helpful.

• Ubuntu: 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.)

• Office 365 Powershell - Export user, license type, and company field to csv file

  - by ASGJim

  I need to be able to export user name or email address (doesn't matter which), company (from the company field under the organization tab in a user account of the exchange admin console), and license type (e.g. exchange online e1, exchange online kiosk etc...) I am able to export both values in two statements into two separate files but that doesn't do me much good. I can export the username and license type with the following: Get-MSOLUser | % { $user=$_; $_.Licenses | Select {$user.displayname},AccountSKuid } | Export-CSV "sample.csv" -NoTypeInformation And, I can get the company values with the following: Get-User | select company | Export-CSV sample.csv Someone on another forum suggested this - $index = @{} Get-User | foreach-object {$index.Add($_.userprincipalname,$_.company)} Get-MsolUser | ForEach-Object { write-host $_.userprincipalname, $index[$_.userprincipalname], $_.licenses.AccountSku.Skupartnumber} That seems like it should work but it doesn't display any license info in my powershell, it's just blank. Also I wouldn't know how to export that to a csv file. Any help would be appreciated. Thanks.

• Issues with Rsync on a NAS

  - by Daniel Fischer

  I'm trying to rsync a few external hard drives over to my new Nas DS412+ but I'm noticing it's stupid slow. I'm trying it via mounting the backup folder via afb on a Mac. I was told this may be the wrong way to do it. I recently just turned on "network backup" on the Synology and am now running rsync over ssh like: rsync -ar --progress . admin@localip:/backup/path Is this the right way to do it now? Will it be faster? Is there something else I can do to make it faster? Edit: I'm getting a ton of: "failed to set permissions" "failed to set times" now that I run it. What do I do?

• Bioshock2 installer is not running under windows 7 64bit

  - by kaykay

  When I try to install the Bioshock2 game under windows 7 64-bit i get the following error- "The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher." I try to run it in compatibility mode (as XP and admin) I get the same error. I don't understand why it is giving me this error because if it is 32bit program then it should just run like other 32 bit application I have. And I am sure Bioshock2 is not a 16bit game. What can I do to run this program? It ran on Windows XP in the past.

• Apache/passenger/ree doesn't interpret .rb files

  - by Sergey

  I'm trying to get apache + passenger + ree to work. I think I did everything (except for setting up rails env - for now I wanna run just pure ruby) described here: http://rvm.beginrescueend.com/integration/passenger/ But when I try to go to localhost/test.rb it doesn't interpret that file and just download it. I don't know where should I look for mistakes, so here are a few files I think could be relevant: /var/log/apache2/error.log (these 2 lines are repeating) [Mon May 31 23:12:47 2010] [notice] Graceful restart requested, doing restart [Mon May 31 23:12:48 2010] [notice] Apache/2.2.14 (Ubuntu) PHP/5.3.2-1ubuntu4.2 with Suhosin-Patch Phusion_Passenger/2.2.11 configured -- resuming normal operations /etc/apache2/httpd.conf LoadModule passenger_module /home/sergey/.rvm/gems/ree-1.8.7-2010.01/gems/passenger-2.2.11/ext/apache2/mod_passenger.so PassengerRoot /home/sergey/.rvm/gems/ree-1.8.7-2010.01/gems/passenger-2.2.11 PassengerRuby /home/sergey/.rvm/bin/passenger_ruby /var/www/test.rb puts "test"

• Is there a way to launch a command within a proper zsh shell ?

  - by Wam

  I'm not really clear with my question here, let me rephrase it : I've setup a launch_workspace.sh to launch directly tmux with 5 different commands loaded. Here is my current content : #!/bin/sh tmux new-session -d -s scube -n 'vim' "vim" tmux new-window -t scube:2 -n 'server' "$SHELL -c 'script/rails server'" tmux new-window -t scube:3 -n 'yard' "$SHELL -c 'bundle exec yard server --gems'" tmux new-window -t scube:4 -n 'spork' "$SHELL -c 'bundle exec guard'" tmux new-window -t scube:5 -n 'autotest' "$SHELL -c 'bundle exec autotest'" tmux new-window -t scube:5 -n 'shell' "$SHELL" tmux select-window -t scube:1 tmux -2 attach-session -t scube Problem is : my zsh ($SHELL beeing zsh) launches said commands, but when I Ctrl+C any of these, it closes the full zsh (hence my tmux window) and not just return to a proper zsh prompt. Is there a way to have said behavior, to launch zsh with a command and return to a zsh prompt when the command fails ? Cheers

• Any command line tool checking windows domain password?

  - by Chen Jun

  Does Windows provide a command line utility that lets me check a domain user's password? It is sufficient that the utility returns success(0) if I provide a matching domain user name and password. Alternatively, is there a simple VB/JS script that can do this? I'm the Intranet admin of my company and have the default password set for corporate staff, so I'd like to quickly scan which users have not changed their default password. Better yet, are there any books or websites which cover such topics so that I can get more information?

• Install Ruby 1.8.7 on Fedora 11/12

  - by tadman

  Is there a simple way to install Ruby 1.8.7 on Fedora 11 or 12 without side-stepping the yum/RPM package management system too severely? Building from source is always an option, but it tends to deploy things in irregular places and proves to be more fuss to maintain in the long run. A self-built RPM is okay, but I'm presuming there's a .rpm out there somewhere already. Rails is not especially happy with 1.8.6 and the Fedora community, for various reasons, considers 1.8.7 to be toxic and best avoided.

• Share laptop Wi-Fi with router set up as access point via ethernet cables

  - by obie

  I have an ADSL modem which serves as a wireless router. There's a laptop connected to it through cable. On the other room I have a laptop which is connected through the router wirelessly. Since I have other appliances that need to get connected but are not Wi-Fi capable I have another Wi-Fi router. How can I share the second laptop's Wi-Fi with the second router so that the router can then serve as an access point to give internet to my other appliances through ethernet cables? I want something like this: INTERNETMODEM (WIFI)LAPTOP 1 (WIFI)LAPTOP 2 (WIFI)Router 2 (ETHERNET)DREAMBOX & WDTV What I've tried so far is opened the admin interface of router 2 then set static IP 192.168.100.13 and disabled the DHCP. The DHCP of the main router starts with 192.168.100.1 then I hooked up router 2 with the laptop 2 through Cat5 cable but for some reason it's not working.
