• Remote site AD design (2003)

  - by Boy Mars

  A remote site has about 25 of our 50-ish employees. They have their own AD domain presently (2003) but I want to look at getting them onto the same global domain for ease of access/administration. The remote site has a VPN link but line speeds are very poor. I am already aware of tools like ADMT and have done a few migrations in the past (NT/2003 domains), but this is the first time I have the luxury of designing how this domain is organised. So I'm looking for tips on good AD design; would a remote site be better served as a sub-domain? would this reduce traffic? I am only currently looking at 2003 since only existing machine will be used.

• Advice wanted on advanced Linux certification/courses including RHCA

  - by nitins

  I have been working in Linux administration for 2.5 years. I would like to have a certification in this. Yes RHCE is an option. I think I already know most of the RHCE stuff. But I would like to have something advanced. I am ready for a full time course as I am not getting the exposure in my current company. Please give me suggestions about training/courses. I have found a course called RHCA(Architect). Is this a good course?

• Advantages of Terminal Server instead of normal client-Server installation?

  - by Sam

  What are the advantages of using a (Windows) Terminal Server and thin clients instead of using a normal Server and full clients? So far I've only really used normal servers and clients, but now customers ask about terminal Server, and I'd like to know pro's and con's of using them instead of an "old-fashioned" client-server network. Some things I can guess: easier administration (don't need to install/update office/stuff on 20 computers but only on the server). Easier backup (no need to backup client computers). And I'd guess it would be hard (impossible) to connect and use local (like USB) hardware with Terminal Server? What else are the reasons for or against switching to Terminal Server?

• Any good PostgreSQL client for linux?

  - by senotrusov

  stackoverflow points me "belongs-on-serverfault" on this, so crossposting. I am frustrated of not having a good Linux GUI administration and development tool for PostgreSQL. pgAdmin III is buggy and unusable piece of... hmm, software, compared to Windows-only PostgreSQL Maestro and EMS PostgreSQL manager. phpPgaAmin does not looks promising. EMS PostgreSQL manager can work under Wine, but such setup have a number of issues. Requirements are: Table data editing and browsing for large tables (1M+), able to jump by FK or some master-slave editing, GUI filtering and so on. ER diagrams with in-place schema editing Schema editing and browsing with all useful GUI support Schema changes log to put into DB versioning (migrations script). Tabbed interface to be able to work with a number of tables and SQL queries at once. And so on. Any ideas?

• Sharepoint Services 3.0: 403 Forbidden fun

  - by gravyface

  Can't get to the Administration or the "companyweb" site itself; was working up to a week ago. Old threads, blog posts, etc. indicate that there was an issue with a KB update but was resolved when .NET Framework 2.0 SP1 was deployed/installed. Running Process Monitor, I can see a lot of PATH NOT FOUND','NAME NOT FOUND for c:\inetpub\companyweb\Default.aspx, \_themes\ice\...\foo.css, etc. for the w3wp.exe process on CreateFileorQueryOpenoperations. These files do not exist in the location specified. I don't recall these files actually existing in that folder, but I believe they're "created" when requested, pulled in from Common Files/Shared or whatever, in typically-awesome Microsoft Web architecture land (</rant>). Besides reinstalling (which I'm sure will be as much fun as migrating from one server to another was), anyone know what's going on? Google-fu has alluded me.

• Alternatives for heapdumps creation with higher performance than jmap?

  - by Christian

  Hi, I have to create heapdumps, which works nice with jmap. My problem is, that jmap takes very long to create the heapdump file. Especially when the heap is getting bigger ( 1GB) it is taking too long. One situation as example: When the server gets into trouble with the heapspace, I want to restart it automatically and create a heapdump before the restart. This works, but takes too long to write the heapdump. This way the server is down for too long. The heapdump creation takes longer than one hour. I know about -XX:+HeapDumpOnOutOfMemoryError, but most of the time I can find the memory problem before the exception is thrown by the jvm. Is there an alternative to jmap which writes the heapdumps faster? A special solution for the example above would also be appreciated. This question is a mix between programming and system-administration, but I think I'm at the right place here.

• What kind of server do I need to handle 10 million requests and mySQL queries a day?

  - by Calvin

  I'm a new bie of server administration and I'm looking for a powerful hosting service to host my new website. This website is basically a back-end of an mobile online game, and it will: handle up to 10 million of HTTPS request and mySQL queries a day store up to 2000 GB file on the hard disk transfer probably 5000 GB data in and out per month it runs on PHP and mySQL have 10 million records in mySQL database, for each record there are 5-10 fields, around 100 bytes each I really don't know what kind of a server I need to handle these requirements, my question is: what cpu/ram do I need for a dedicated server or vps? what hosting companies are able to offer this kind of dedicated server or VPS? what about cloud computing? I've researched Amazon EC2 but it seems complicated to me. And I've contacted Rackspace but strangely they said Cloudsites is not suitable for my requirements. I wonder if there is other cloud hosting company. any other alternative method? thanks very much!

• create print server port via command line error Win 8

  - by Benjamin Jones

  I need to create a Print Server Port via commandline in Windows 8 Per Google search I should be using prnport.vbs script to do so: cscript c:\Windows\System32\Printing_Admin_Scripts\en-US\prnport.vbs -a -s \\192.168.113.253 -r Xerox_192.168.113.253 However I get this error: ** Unable to connect to WMI service Error 0x800706BA The RPC Server is unavailable. ** I looked at local services and both RPC and WMI services are started . Also I made sure add remote admin rule to Windows Firewall via command line without success!: netsh advfirewall firewall set rule group="windows management instrumentation (wmi)" new enable=yes netsh advfirewall firewall set rule group="remote administration" new enable=yes NOTE: If I use the GUI to create the print server port then add the printer via command line: rundll32 printui.dll,PrintUIEntry /if /b "Xerox WorkCenter 7535" /F C:\Windows\Inf\WC7545-7556_PCL6_x64_Driver\x2DNORX.inf /r "Xerox_192.168.113.253" /m "Xerox WorkCentre 7535 PCL6" THE PRINTER IS SUCCESSFULLY ADDED. So its NOT the printer it self! So how can I successfully add a print server port via command line? Thanks

• Windows 2008 Incoming Connection: Where/How is Server IPv4 address defined

  - by revelate

  We're evaluating a VM hosted externally which runs Windows Server 2008 R2 Web Server Edition and wish to access it via a VPN connection for maintenance and administration. RRAS isn't included in Web Server Edition, but it does have a form of VPN server called "Incoming Connections". This appears to work well and even supports multiple simultaneous connections. As we'll be using this VPN regularly we'd like to know if this is a viable solution or if we'd be better off upgrading to Standard Edition and full-fledged RRAS. In particular we're accessing the VM via the Private IP given by the Incoming Connection (currently 169.254.135.207) so we'd like know: if the server private IP might change every so often? if so is there any way to define it manually? or should we be using the server name rather than the private IP address? if so how can we be sure that it will resolve correctly? Name resolution over the "Incoming Connection" has worked on and off during our tests. Thanks for your help

• SonicWall and Windows CA

  - by Nathan C

  I'm attempting to import a certificate created by a CA I've set up in Windows using AD CS. I've done the following: 1) Created my own CA (MyCompany) 2) Enabled web services (mostly for ease of configuration) 3) Generated a certificate request on the Sonicwall itself 4) Used web services to sign the certificate 5) Imported the sign certificate into the Sonicwall ...this caused the certificate to show "No" for the Verified field. 6) Imported the CA's certificate. This is where I get stuck. I attempted to import the CRL list, but get the following error: CRL Error - Verification failed using CA certificate. No further errors appear in the logs. Without the CRL list the certificate won't verify and it doesn't appear under the "Administration" page so I can select it for use via HTTPS. Any ideas?

• Multiple URLs on one domain in IIS 6 [closed]

  - by TGnat

  Possible Duplicate: How to Host Multiple Domains / Web Sites on one IIS6 Server I'm a developer and only know the basics of IIS administration. I want to give each of my clients a personalized URL to access my web site. I have mySite.com and I would like to allow client A to acess the site via A.mySite.com and client B to use B.mySite.com. These would all point the the mySite.com domain with the same ip address. Can this be done in IIS? Do I have to register new domains for each client? Are there other ways to accomplish the same thing?

• Migration of egroupware from one Ubuntu server to another

  - by Chris Schmidt

  I am new to server administration and have been attempting to migrate from one Ubuntu server to another for 4 days now. I am having a problem with migration of egroupware settings. Specifically, I need to find where knowledgebase saves the files on the local machine. I have the database set correctly and its using the previous settings. However, articles in knowledgebase are not showing images associated with them. I have tried everything to find the file on the old server that stores data files uploaded to the knowlegebase but I cannot. If there is another way to import these files, or if someone knows where they are saved, I would really appreciate the help. -Chris

• Is there a way to set access to WMI using GroupPolicy?

  - by Greg Domjan

  From various documentation it appears that to change WMI access you need to use WMI to access the running service and modify specific parts of the tree. Its kind of annoying changing 150,000 hosts using the UI. And then having to include such changes in the process of adding new hosts. Could write a script to do the same, but that needs to either connect to all those machines live, or be distributed for later update say in an startup/install script. And then you have to mess around with copying binary SD data from an example access control. I've also found you can change the wbem/*.mof file to include an SDDL but I'm really vague on how that all works at the moment. Am I just missing some point of simple administration?

• ITIL Incident Classification - Fault vs SR vs Technical Incident

  - by ExceptionLimeCat

  I am new to ITIL and Incident classifcations and I am trying learn more about them and understand how they could integrate in our organization. I have found it difficult to find a clear definition of Fault vs. Service Request vs. Technical incidents. I am basing my definitions on this article: http://www.itsmsolutions.com/newsletters/DITYvol6iss27.htm As I understand it: Service Request - Service provided by IT as part of regular administration of a system. Fault - An unexpected error in a system. Technical Incident - An interruption or potential interruption in IT service due to an expected incident caused by some IT policy.

• X11Forwarding on MacOSX (Leopard/Snow Leopard)

  - by Shyam

  Hi, I have some remote boxes, which are a bunch of Mac Mini's. I access them now through SSH, and it fits my needs to do the maintenance. In the past, I used X11Forwarding with Linux boxes, when I was still using Debian myself, and I was able to run a specific application as if it was natively present (Firefox). I haven't succeeded to do this yet, but I assume because of the BSD underneath the fancy Apple GUI should be able to do such a task similar. I am aware of the remote administration, but I rather keep access limited to SSH on these boxes for inbound connections. Background information about the why's, tips, advice and comments are all helpful! Thanks!

• Passing all traffic through Cloudflare

  - by Nick

  I am new to Linux System Administration and I am experimenting with iptables trying to learn how to really lock down a system with them. And one thing a friend of mine recommended was that there was a way to pass all incoming traffic through Cloudflare so even if attackers resolved the server ip they still couldn't (D)dos it directly. This is exactly what they said: "Simply config your servers iptables to only allow incoming connections from CloudFlares IP ranges then set it to allow only your IP/IP range to connect on port 21 (SSH)" Could someone help me on what command I'd need to run for Ubuntu to get this effect?

• What is a good hosted email service?

  - by rhooligan

  I am looking for a hosted email service for a handful of email accounts. It needs to be very reliable and provide a nice web mail interface. I would like an admin where I can manage accounts. I've used Communigate before, it's functional but ugly. Exchange web mail is feature rich enough, but isn't as performant as the later two contestants. I am currently paying $50/yearly for hosted Gmail through Google. The features of the web email client are fine for personal use, but not flexible enough for professional use. The administration tools also suck. In short, I want a hosted service with a better experience than gmail or Communigate but is still speedy.

• CentOS connect to the internet

  - by Delirium tremens

  I installed CentOS, but it didn't automatically connect to the internet. Is that the normal behavior? I have Ethernet Broadband Router DI-604 and WebStar DPX2203 series Cablemodem with EMTA . What should I do to connect to the internet? Update: A cousin told me my ethernet adapter or network board will depend on my motherboard. My computer upgrade document says the motherboard is gigabyte video onboard. I heard gigabyte's network adapters are Gigabit or Realtek. In CentOS, System - Administration - Network - New - Ethernet, first, only "Other Network Board" was listed, so I selected it and clicked Next, then there wasn't Gigabit, but there was Realtek, so I selected Realtek. I heard with Net Virtua selecting dhcp the things first answered asked me to tell first answerer are automatically configured. So I tried Realtek with dhcp, but it still didn't work.

• How to set Brocade 200E SAN Fabric Switch Port Health Monitoring to "monitored"

  - by Kenny

  Hi, I have a Brocade SAN Fabric Switch, a 200E. When using the web based management interface "SwitchExplorer" I can click the port, and I see "Port Administration Services". In the first screen of data that appreas, there's a row called "Health" which has value "Unmonitored". Do you know how to set this port to be Monitored? And if also - what "Health" monitoring does? I'm hoping it'll email or log if there's a connection or disconnection.. Many thanks for looking... Kenny

• django fcgi - call a management command with subprocess.Popen

  - by user41855

  Hi, I'm using an app called django-chronograph. It has a code of line which works in my dev environment and does not work in production: p = subprocess.Popen(['python', get_manage_py(), 'run_job', str(self.pk)]) This line crashes in production with: unknown command run_job Whereas when I run directly from command line: manage.py run_job It works fine. Interestingly it worked once when we exchanged 'python' with 'usr/bin/python'. then we restarted the server once more and it was back to old behaviour. Thus it seems as we have a python path issue. I'm not the guy who is running the server, its my app that should run and it would be great to get some help here. Attention: I'm a total noob regarding server-administration.. server environment: NGINX with FCGI-Daemon FCGI in prefork-mode

• What is your IT-department to staff ratio?

  - by Bart Silverstrim

  This is a topic that may be rather political but it related to system administration still...how many people do you have supporting your users in your IT department? We have three people supporting something near 1500 systems and around 2400 people and a recent question was raised about why we have long times to get systems replaced, repaired, work orders fulfilled, etc. along with the system admin duties of maintaining the servers (mail, proxy, filters, VOIP, wireless, backup, etc.) Does anyone have numbers on what the "best practices" average is of support people to employees in an organization? EDIT:...from some of the answers that are appearing I'm starting to feel depressed...

• search solution to integrate community mailing-lists into a website on shared hosting

  - by Thomas Traub

  The community (300 members), cocktailnetwork, has a website, cocktailnetwork.eu and about ten mailing lists. We want to manage the mailing lists from inside the website (lists and subscribers) and link the list's informations with the member profiles on the site. We are on shared hosting. The community members use the lists to send mails to all other members / groups of members. They can subscribe / unsubscribe from a list. The administrators can in addition create / delete / modify lists. Right now I use ezmlm with QmailAdmin, the lists are completly seperated from the website. I could link the data via remote administration commands, but that's not very satisfactory, does not allow the creation of new lists and it's an deprecated feature of our hosting package, sooner or later we'll need to switch anyway. Do You know of an elegant solution for us ? Any web service with a good, stable API ? Thanks.

• Internal+external interfaces with multiple default gateways on win2003

  - by fileitup

  Im trying to set up several web servers for a load balanced cluster and need to have each server connected to the internal network (for load balancing) as well as to an external network (internet - for administration). I have two NICs but since I cant set two default gateways I have the external gateway as default and the internal as a route rule. This setup only works half way - the internal network is fine but I cant log in from outside or see the web from the box. If I switch the gateways remote login/web will work, but the internal wont. Im sure someone encountered this before but wasnt able to find anything online. Any help will be appreciated.
