• How do I protect my company from my IT guy?

  - by Jesse

  I'm going to hire an IT guy to help manage my office's computers and network. We're a small shop, so he'll be the only one doing IT. Of course, I'll interview carefully, check references, and run a background check. But you never know how things will work out. How do I limit my company's exposure if the guy I hire turns out to be evil? How do I avoid making him the single most powerful person in the organization?

• Why do clients on Branch Sites insist on accessing SYSVOL on the HQ DC instead of the branches' RODC?

  - by pepoluan

  I'm still scratching my head over this situation... You see, we have 3 RW DCs in the HQ, and 1 RODC on every branch sites (50+ locations). During startup, a script will pull in some files from \\example.com\SYSVOL\example.com\Common\Data But we have been experiencing bandwidth overload. A traffic analysis indicated that lots of clients in the Branch Sites were trying to access the SYSVOL located in the RW DCs. E.g.: If the RW DCs are 10.1.0.15, 10.2.0.15, and 10.3.0.15, and site 'X' has a subnet of 10.27.0.0/16 (with its RODC at 10.27.0.15), clients at site 'X' seem to insist on accessing \\10.1.0.15\SYSVOL or \\10.2.0.15\SYSVOL or \\10.3.0.15\SYSVOL; they seem to be ignoring the RODC completely. What is going on here? Where should I start investigating what went wrong? BTW, I'm already using DFS-R, and replication have been going on successfully; I can put a small 'canary' file on one of the RW DCs, and within minutes all the RODCs will have successfully replicated the 'canary' file.

• How to find the computer name a user logged on to

  - by V. Romanov

  Is there a tool or script or some other way of knowing what computer name a specific user is currently logged on to? Or even was logged on to? Say the user "HRDrone" is working on his machine whose hostname is "HRStation01". I, sitting at my sysadmin desk, only know that the username is "HRDrone". Any way i can find out that he is logged on to "HRStation01" without asking the user? AD event viewer? anything? Thanks!

• Dynamically hosting new domains on Apache

  - by Kunal

  I'd like to dynamically be able to host client's domains, with just having to provide them instructions like this: http://www.tumblr.com/docs/en/custom_domains I'm running a pretty typical LAMP stack; any good tutorials for configuring this for Apache, or other server-side configurations I need to be aware of?

• Disable the user of Internet explorer through policies when called from HTML help

  - by Stephane

  Hello, I have a locked down environment where users are prohibited from doing, well, basically anything but run the specific programs we specify. We just switched a program from using the venerable "WinHELP" help format to HTML help (CHM) but that seem to have an unwanted and rather dangerous side effect: when a user click on a hyperlink inside the HTML help, a new internet explorer window is opened and the user is free to browse and do terrible things to my server (well, not that much, but still...) I have checked the session in this case and the IE window is actually hosted within the help engine: there is no iexplore.exe process running in the user session (and it cannot: it's explicitly prohibited). We have disable all help right now until we find a solution. I'm working with the help team to have all external URLs removed from the help file but that is going to be a long and error-prone task. Meanwhile, I've checked all the group policies option but I have to say that I was unable to find anything that would prevent a standalone IE window hosted in a random process from running. I don't want to disable WinHTTP or the IE rendering engine or anything of the sort. But I need to prevent all users members of a specific AD user group from ever having an IE window displayed to them. The servers are running Windows 2003 and Citrix metaframe 4.5. Thanks in advance

• Using mod_wsgi with mpm_itk: socket permission issue

  - by djechelon

  I'm using mod_itk as MPM for increased security in shared environment. I also have a Firefox Sync Server within one of the VHosts I host. That vhost is restricted to a certain user via AssignUserId user group. The problem is that the socket /var/run/wsgi...whatever.sock is chmodded srwx------ and owned by Apache's wwwrun. While I configured the vhost with WSGIProcessGroup sync WSGIDaemonProcess sync user=djechelon group=djechelon processes=1 threads=5 I still get the error that Apache wants to access a socket that is not accessible and because of this gets an error. Is it possible to configure mod_wsgi in order to create different sockets with different owners for different applications or to chmod its socket in a different way (less secure)? Currently, I'm running Firefox Sync as the only WSGI application. Moving it to a vhost that doesn't AssignUserId could solve this problem but will force me to change URL (and buy an additional SSL certificate), so I wouldn't consider this

• Mass bulk add domains to web hosting service (possible?)

  - by Scott

  I was wondering if anyone does bulk adding of domains to your web hosting provider (Amazon, Linode, Rackspace, etc). I am thinking of creating a product that allows user to host their site on top of my web hosting and want something that can allow me to bulk add domains (and point DNS to my web hosting DNS) with as little manual work as possible. I am thinking of getting a VPS to do this. Is this possible even? Thanks Scott

• Building a Web proxy to get around same-origin restrictions for collaborative Webapp based on a MEAN stack

  - by Lew Cohen

  Can anyone point to books, articles, blogs, or even applications - open-source or proprietary - that detail building a Web proxy? This specific proxy will exist to get around the same-origin restrictions that prevent, for instance, loading a given Website into an <iframe> in a Webapp. This Webapp is a collaborative application in which a group of users log in to the app's Website and can then load different Websites into this app's <iframe> and do various collaborative things (e.g., several users simultaneously browsing a Website, in synch). The Webapp itself is built on a MEAN stack (MongoDB, Express, AngularJS, and Node.js). The purpose of this proxy is not to do anonymous browsing or to bypass censorship. Information on how to build such a vehicle seems not to be readily available from my research. I've come across Glype but am not sure whether this is a feasible solution. I don't want to reinvent the wheel, so if a product is available for purchase, great. Else, we'd need to build one. The one that seems to be close is http://www.corsproxy.com. In effect, we'd like to re-create this since it evidently does what's needed. I don't care what server-side technology is used. Our app is MEAN-based, if that has any bearing. Also, the proxy has to obviously honor basic security considerations (user cookies, etc.) and eventually be scalable. So, anyone know of any sources that would detail how to build one of these? Is it even worth building if something already exists? If so, what would be a good candidate? Any other issues that should be considered with this proxy/application? Thanks a lot!

• MX records not correctly updated by the Google DNS servers

  - by Mac_Cain13

  We are currently losing some e-mail and we discovered that this is caused by a wrong DNS setting. We used a CNAME for our MX record an thats not allowed. So about 2 weeks ago we changed it to an A-record to fix the problem. It seems all major DNS services (like OpenDNS and ISPs) have synced their records and are returning correct results on our DNS queries. But Googles DNS service (at 8.8.8.8) is still returning the CNAME values and we still some e-mails are not delivered correctly. Query on OpenDNS: ; <<>> DiG 9.7.3-P3 <<>> mx wrep.nl @208.67.222.222 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 51231 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;wrep.nl.

And how can we get Google to update their DNS records correctly? Any help is very appreciated. (Please note that other domains that are managed by the same DNS servers/tools are working fine.)

• Comprehensive solution for managing patches, event viewing, change management, inventory, etc

  - by Holocryptic

  I'm looking for a solution that incorporates most or all of the following: Patch Management, Server event viewing/tracking, AD change management, ticketing and internal/external kb, remote access - ability to shadow user sessions or create new ones, imaging, and inventory. Our environments contains Windows Servers and ESXi Hosts (We're not completely virtual, but we're moving that direction). Various Cisco and Linksys switches and firewalls. This is a tall order, and I don't know if it can be done on a reasonable budget. I've looked and found some questions on SF that deal with some of this: http://serverfault.com/questions/72015/active-directory-management-tools-for-medium-sized-forest-less-than-1000-users http://serverfault.com/questions/4021/are-there-any-tools-to-do-change-management-with-active-directory-group-policy http://serverfault.com/questions/21752/what-is-a-good-patch-update-management-server What I'm ideally looking for is a reasonably cheap solution that integrates the features into a central interface. We're a non-profit, so money is a limiting factor (the cheaper, the better; but we have a max of $15k). What we are trying to avoid is having to deal with multiple vendors, while maintaining scalability (we're creating more sites that we'll have to manage). Is this possible, or will we have to cobble together something to make it work for us?

• Starting with administering a linux box

  - by Josh K

  I'm rather new to this, and I'd like to play with administering a linux box. Things I need to know how to do: Setup subdomains Setup FTP accounts Setup full domains / add domains MySQL setup / install / management LAMP setup / install / management This is probably going on a CentOS distro. I'd like links or a break down on how I can learn to do this. I am comfortable with a command line, but I'm trying to move from shared hosting to a VPS and would like to have some idea on how deep the water is before I do.

• Setting DNS suffix for multiple network adapters in a VM

  - by arun_bh

• Copy files between two windows machines on seperate domains

  - by Simon

  I need to copy several database backups between two computers. The source computer initiates the copy and is a Windows 2000 pc and is a member of domain1. The destination machine is running Windows Server 2000 and is a member of domain2. The machines are on separate networks physically connected via a firewall. The files are currently copied via ssh with http://sshwindows.sourceforge.net/ installed on the destination machine. There is no need to encrypt the contents during the copy, however the passwords should not be sent in the clear. I am looking for a way to copy the files without having to install a server on the destination. I specifically need help with how to set up the permissions and what ports would need to be opened on the firewall.

• Spawned Process Terminated in GP Startup Script

  - by Charles Gargent

  I have a Group Policy Startup Script which runs synchronously. I now need this script to run one process asynchronously. So far I have managed to get the spawned process running via the command below, however once the rest of the script finishes and the GP Startup Script "phase" finishes and the logon prompt is shown, my spawned process is terminated. Is there any way to have this process continue beyond the Startup Script phase? cmd /c start spawned.bat I guess the reason why it terminates is because the process was launched by the Startup Script process and when the parent process terminates so do its children. PS I need it to be launched via the exisitng script.

• How to set up memcached to use unix socket?

  - by alfish

  While I could use memcached on Debian to use the default 11211 port, but I've had great difficulty setting up unix socket, Form what I'v read, I know that I need to create a memcache.socket and add -s /path/to/memcache.socket -a 0766 To /etc/memcached.conf and comment out the default connection port and IP, i.e. -p 11211 -l 127.0.0.1 However, when I restart memcached I get internal server errors on Drupal site. I'm trying to implement unix sockets to avoid TCP/IP overhead and boost overal memcached performance, however not sure how much performance gain one can expect of this tweak. I appreciate your hints or possibly configs to to resolve this.

• Apache Redirect from https to https

  - by Nikolaos Kakouros

  I am trying to redirect without a rewrite rule from eg https://www.domain.com to https://www.domain.net . I have a wildcard certificate for *.domain.net . This yields the following warning in my error_log [warn] RSA server certificate wildcard CommonName (CN) `*.domain.net' does NOT match server name!? This makes sense and I understand why the warning. I would like to ask if there is a way to use the Redirect directive to accomplish the above without the warnings. Here is my virtual hosts in ssl.conf: <VirtualHost *:443> SSLEngine on ServerName www.domain.net DocumentRoot /var/www/html/domain SSLOptions -FakeBasicAuth -ExportCertData +StrictRequire +OptRenegotiate -StdEnvVars SSLStrictSNIVHostCheck off </VirtualHost> <VirtualHost *:443> SSLEngine on ServerName www.domain.com ServerAlias www.domain.info Redirect permanent / https://www.domain.net </VirtualHost> Also, if there is a solution, can it be used for redirection from htps://domain.com to htps://www.domain.com? Thanks a lot!

• Computers "applying computer settings" for a long time on start-up...why?

  - by tombull89

  Hello. Might be a bit of a slong shot but I'm stumped, along with the ICT Manager for the school I'm working it. In one of the IT rooms when you switch a computer on it will boot through BIOS fine, but when it gets to "applying computer settings" it can hang for a long time (~15 minutes). If you unplug the computer from the network it starts up fine, gets to the login screen, then you can plug the network cable in and it will work fine. I don't think it's anything to do with the fact we've been coming close to running out of IP addresses or a problem with our DHCP. Microsoft KB says apply the latest service pack, which we've done, and check a service. Servers and domian controllers are S2003, Computers and Desktops are XP. Does anybody have any thoughts on what to try?

• Host multiple domains with Apache on a VPS

  - by Kunal

  Hi I have recently bought a windows VPS and installed apache, mysql using xampp. All services are running fine. I can access the hosted site using the IP of VPS but what I need to do is host multiple domains on that server. Actually my requirement was to use htaccess on a php based site but the site had to access data from ms sql server as well. So needed to enable php_mssql.dll in the php.ini which no shared hosting was supporting. Had to go for this VPS. Plesk was installed by default but as htaccess wont work with IIS, I had to stop IIS service and install apache there. Now all is well, but I need to find a way to host multiple domains there. When I bought the VPS they hosting people sent me the dedicated IP of the server and also I have the 2 name servers required to host domains. What is the next step? Exactly which file I need to modify to get things done? Please help! Any kind of help is much appreciated. Thanks in advance for all of your kind help and time.

• What is the difference between a plain Amazon ec2 instance and beanstalk?

  - by Alex Ford

  I am a solo developer and the sites I'm deploying are very small, usually hobby sites and I have a few questions about the Amazon services. Is there a reason for me to use beanstalk or should I just stick with a single ec2 instance? Should I use RDS for database? I heard someone say that I could just install a database on my ec2 instance, making it cheaper. I'm trying to keep everything as cheap as possible. I need to point custom domains to my sites. Pretty sure that means I have to deal with elastic IPs. Do those work with beanstalk or only with individual ec2 instances? Thanks in advance!
