• SQL 2008 Database tuning advisor won’t start

  - by Andrew Hancox

  For some reason I can't get DTA to connect to my development machine. It connects to a remote DB just fine but when I point it to my dev machine I get an error saying: Failed to initialize MSDB database for tuning (exit code: -1073741819). I'm pretty sure it's not a permissions issue since I've used profiler to capture what it's doing and all of the commands it's run so far look fine and are being run under my account which is associated with the sysadmin role, when I run them in sql management studio they go through fine. I'm pretty convinced that the problem is related to creating the objects in MSDB that are used by DTA but I tried creating these manually (I found scripts on the web) and it just seems to push the problem along the line slightly. I'm going out of my mind - have even tried reinstalling SQL but that's not fixed it. I'm using SQL 2008 with SP1 (10.0.2531) on windows server 2008 (patched up to date). SAVE ME!!!!!

• Make windows 7 client compatible with windows 2003 server

  - by caspert

  Hi, I am sysadmin for a small business with 30 clients. We have a server running windows 2003 and all the client-computers run windows XP. Now this is not an important issue, but it would be nice if it worked. My personal (home) computer is running windows 7 RC. When I bring my home-computer to work and log into the network with domain\username it logs me in just fine. Although, approving my profile, letting me into the network, including all network drives and printers, it does not download the profile fully. I do believe it might be getting the roaming profiles. So all my user- items, documents etc. attached to the profile does not show up on Windows 7. Is there any way to make it fully download the profile? as it does with Windows XP.

• mysql UDF : fopen = permission denied

  - by lindenb

  Hi All, this is question I already asked on SO but I wonder if this could be a SysAdmin problem. I'm trying to create a mysql UDF function , this function calls "fopen/fclose" to read a flat file stored in /data. But using errno (yes, I know it is bad in a MT program...) I can see that the function cannot open my file: "Permission denied" I tried to do a chmod -R 755 /data (as well as 777, chown -R mysql:mysql /data etc...) but it didn't change anything. when I copied the flat file to /tmp : OK, my UDF was able to 'fopen' the file. I'm puzzled. currently , I've got: drwxrwxrwx 4 pierre root 4096 2010-05-26 16:51 /data drwxrwxrwx 3 pierre root 4096 2010-05-18 09:41 /data/dir1 drwxrwxrwx 3 pierre root 4096 2010-05-18 09:41 /data/dir1/dir2 drwxrwxrwx 4 pierre root 4096 2010-05-18 10:27 /data/dir1/dir2/dir3 -rw-r--r-- 1 pierre root 50685268 2005-12-10 00:01 /data/dir1/dir2/dir3/myfile.txt Any idea ?

• How to allow users to monitor performance of a set of servers without touching every server?

  - by Jon Seigel

  I'm not a sysadmin, so this may be trivial. We have about 20 Windows Server 2008 R2 VMs we want to monitor centrally using Perfmon. The only issue is that the user account that's going to be doing the monitoring is not (and I assume will never be) in the Administrators group. The servers, and the user account (currently one, but could be more) are all on the same domain. Right now we're running a pilot with 5 of the servers, touching each VM manually to set the permissions, which is already getting cumbersome to manage. If we decide to roll this out to all the servers, we need a scalable solution to control access. What is the most flexible way to accomplish this? I'd like a solution that would work with 200 servers just as easily as the 20 servers we have now.

• CentOS - PHP - Yum Install with Custom ./configure params

  - by Mike Purcell

  I have successfully configured and compiled php on my dev server, and works great, but after talking to a sysadmin buddy, he informed that custom compiles of the latest builds are not recommended for production (or even development) systems. He noted a situation where they custom configured and compiled PHP 5.3.6, only to find that there was some issue with a low-level Postgres driver, so they had to revert back to 5.3.3. So I am considering going back to yum to install PHP, however I have several custom configuration settings and was wondering if it's possible to pass or configure how PHP will be compiled through YUM? My current configure line: Configure Command => './configure' '--with-libdir=lib64' '--prefix=/usr/local/_custom/app/php' '--with-config-file-path=/usr/local/_custom/app/php/etc' '--with-config-file-scan-dir=/usr/local/_custom/app/php/etc/modules' '--disable-all' '--with-apxs2=/usr/sbin/apxs' '--with-curl=/usr/sbin/curl' '--with-gd' '--with-iconv' '--with-jpeg-dir=/usr/lib' '--with-mcrypt=/usr/bin' '--with-pcre-regex' '--with-pdo-mysql=mysqlnd' '--with-png-dir=/usr/lib' '--with-zlib' '--enable-ctype' '--enable-dom' '--enable-hash' '--enable-json' '--enable-libxml' '--enable-mbstring' '--enable-mbregex' '--enable-pdo' '--enable-session' '--enable-simplexml' '--enable-xml' '--enable-xmlreader' '--enable-xmlwriter'

• Why is business-class storage so expensive?

  - by Mark Henderson

  This is a Canonical Question about the Cost of Enterprise Storage. See also the following question: What's the best way to explain storage issues to developers and other users Regarding general questions like: Why do I have to pay 50 bucks a month per extra gigabyte of storage? Our file server is always running out of space, why doesn't our sysadmin just throw an extra 1TB drive in there? Why is SAN equipment so expensive? The Answers here will attempt to provide a better understanding of how enterprise-level storage works and what influences the price. If you can expand on the Question or provide insight as to the Answer, please post.

• What are some hosted MySQL solutions?

  - by bigmac

  I would like to host a MySQL database somewhere. The basic solution would be to get a VPS, but then I am stuck doing all the sysadmin stuff. It's not terribly difficult if you are not doing anything fancy, but if something goes wrong (like a security breach), it may be hard to resolve or even diagnose in the first place. On the other end of the spectrum, I found Xeround and Amazon RDS. Xeround is not exactly standard MySQL. Amazon seems a bit complex to get started (which is weird because they specifically say it is "simple to deploy"). Why is there nothing in the middle? Is there no demand for a basic hosted MySQL solution?

• Building php-devel package from source (php 5.3)

  - by BajaBob

  I am building PHP 5.3 rpm packages for our custom CentOS 5 yum repo. I am fairly new to building rpms to be honest, but I have had moderate success downloading the SRPMS for a given package and repackaging them using "rpmbuild --rebuild" command. One thing that is throwing me off though is how to satisfy the php-devel package.. I obviously have the PHP 5.3 source files as I was able to build my php-common and other packages with it. But I am not sure how to actually build the devel package! From what I understand, I already have most of what I need - the latest php 5.3.5 source tarball. However I am not sure how to build the correct .spec file to satisfy what I need. If you are knowledgeable in this area, would you mind helping a fellow sysadmin out? Sharing a spec file or at least giving me some pointers on how to approach it. Thanks much serverfault community! -BajaBob

• ms sql 2005 server role problem

  - by Brandon

  On one of our sql 2005 servers we are no longer able to give any users server roles (ex. sysadmin). It appears to be successful both through the UI and through code. But when we check in the db and in the UI the role is unchecked and not shown for the user in the master db. Permissions don't seem to be the issue as we are testing this as system administrator levels of access. There are also no errors in the log. Any ideas? Thanks, Brandon

  - by soultaker

  after I removed an active directory domain service, I lost all my accounts...then not only the SQL server and the TFS stopped working, the TFs administration console also says that I don't have sufficient right to add members...

• Virtualmin Configuration

  - by Allen

  I am trying to get Virtualmin setup and have reached a point where my noobish sysadmin skills aren't getting the job done. This is the message I get now when I try and refresh the configuration of Virtualmin. BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server XXXXXX is not a fully qualified domain name. Sendmail is only accepting SMTP connections on the following ports : 127.0.0.1 port smtp. Email from other systems on the Internet will not be accepted. This can be changed in the Sendmail Mail Server module. Please advise what I need to do to get Sendmail configured properly. Thanks!

• sendmail user unknown - debian lenny

  - by Rimian

  My php's mail() function just stopped working a short while ago. It's started returning FALSE. I am not much of a sysadmin so please forgive my ignorance. I set my php.ini send_path option to: "sendmail_path = /usr/sbin/sendmail -t -i" and restarted apache. Then, I learnt how to test sendmail like so: sudo /usr/sbin/sendmail -bv [email protected] [email protected]... deliverable: mailer esmtp, host example.com., user [email protected] The example email is a real mail box. I have also seen unknown user messages in the mail log. Can anyone please help me debug this? Cheers, Rim

• Setting-up Windows Server 2003 as an L2TP/IPSEC VPN server

  - by andyjohnson

  I'm looking for a pointer to step-by-step instructions for setting-up a Win Server 2003 Std box as a L2TP/IPSEC VPN server. I don't need to use certificates - pre-shared key is sufficient - and the server isn't on a domain. All the sources of information I've found assume a level of sysadmin experience that I don't have - which is why I'm looking for a step-by-step description. I'm a experienced developer, not an IT person, but I have what I'd guess is intermediate level experience of configuring/administering small-scale servers, and have set-up OpenVPN-based VPNs on Windows.

• "Target the specific user you will be using and assign it user id 0/group 0"

  - by Jeremy Holovacs

  I am trying to virtualize an Ubuntu machine using VMWare vCenter Converter, but ran into permissions issues. I followed the instructions of part 1 and 2 on this page but when I got to "For Ubuntu operating systems further configuration is needed" I started running into trouble. I'm decent at Linux, but I'm not an experienced sysadmin. How do I Target the specific user you will be using and assign it user id 0/group 0? How do I Ensure that you also still enable Allow root to ssh even though you are not using the root account? Thanks for your help.

• Setting Sql server security rights for multiple situations

  - by DanDan

  We have an application which uses an instance of Sql Server locally for its backend storage. The administrator windows login has had its sysadmin right revoked, and instead two sql logins have been created; one for the application with a secret password and one read only login we let users view the raw data with. This was working fine until we moved on FileStreams, which requires intergrated windows authentication. So now the sql server logins must be replaced. As a result, I am now reviewing all of our logins but I am not sure how it is possible. It seems that the application needs full read/write access, yet I still need to lock down writing to the tables so the user cannot login into the database and delete data randomly. Does anyone have any tips for setting multiple levels of security using intergrated windows logins, or can you direct me to any further reading? Thanks.

• Easy Linux distribution with newer packages than Ubuntu?

  - by sweetiecakes

  I'm a programmer and sysadmin, and I'm looking for a better Linux distro to use than Ubuntu. It certainly is a well-polished, nice distribution to use, but a lot of the programs available in the Ubuntu repositories are very old versions. Installing PPA's or compiling from source just isn't very nice. I'd love to use something like Arch Linux that uses a rolling release cycle, but I really don't want to configure my system from scratch, and support for ATI Catalyst drivers is necessary. I just want to pop the CD in, install and start using my computer - just like with Ubuntu. Additionally, if you know of a package like ubuntu-restricted-extras for the distribution, that'd be nice! What do you suggest?

• Coding exercise for Linux Systems Admin?

  - by Prashanth Sundaram

  Hello All, I am preparing for a Systems Admin(linux) role for a big company(top 10 companies) and one of the requisite is knowledge of a language like perl, python or Ruby. I have a phone interview which involves sharing a editor with the interviewer, now what kind of coding exercise can I expect on a phone interview or a regular interview? I have used shell for most of my day-to-day tasks and occasionally Perl and python for bigger tasks. Now I don't expect them to ask Write a script that sync's AD users to LDAP? I don't think data structures, algorithms or sorting questions apply to me role? Can you give me any examples of SysAdmin related coding questions?

• Monitor the shell activity of a user on your Unix system?

  - by Joseph Turian

  Trust, but verify. Let's say I want to hire someone a sysadmin, and give them root access to my Unix system. I want to disable X windows for them, only allow shell usage (through SSH, maybe), so that all operations they perform will be through the shell (not mouse operations). I need a tool that will log to a remote server all commands they issue, as they issue them. So even if they install a back door and cover their tracks, that will be logged remotely. How do I disable everything but shell access? Is there a tool for instantaneously remotely logging commands as they are issued?

• Daily Weekly and Monthly DB backup with logrotate?

  - by benjisail

  Hi, I am currently keeping daily backup of my database by doing a daily mysqldump and by using logrotate to keep the 7 last days of mysqldump. I would like to improve this backup process to keep 7 daily backup, 3 weekly backups and 12 monthly backup. I found this article which explain how to di this with logrotate : http://www.hotcoding.com/os/sysadmin/35751.html However I am using the dateext logrotate option to name my backup files so I cannot use this solution. How can I do daily, weekly and monthly backup with logrotate and with the dateext option?

• MS Word reports files read-only on Win Server 2003 file server

  - by Larry Hamelin

  I'm not a sysadmin, but I play one on TV: I'm trying to fix a problem for my mom's tiny non-profit company's server. I set up a Windows Server 2003 machine as a domain controller and file server. Everything has been working well for a few months, but lately when she tries to save changes to a Word (Office XP) document stored on the server, Word will intermittently report that the file is read-only. Saving to an alternate file in the same directory works, and when she closes Word and re-opens the original document, it'll save changes just fine. No one else ever has these files open. I've checked security and share permissions, and everything's OK. We've tried rebooting the server, but the problem continues, but intermittently. I have no clue what's going on. Help!

• VPN/AFP server for centralized TimeMachine backups

  - by Keith Johnson

  I am a sysadmin for a small group of about 7 people who prefer Apple machines for their work. These machines are currently either a) not backed up at all, or b) backed up using Retrospect(Which I'm not very fond of). I don't really have the budget for anything fancy, and I'd like to keep it as user friendly as possible. Ideally I am thinking of a VPN server they can connect to(to keep the traffic secure, and because they work from home frequently) along with an AFP server for use with TimeMachine. The goal would be to get better backup coverage, along with user-initiated restores and overall ease of use. Does this seem like a reasonable idea? Has anyone done this before? Are there any obvious problems I've overlooked?

• Ideas for home media server with Dell laptop?

  - by Warlax

  Hi guys, We have an old Dell Inspiron laptop we don't use anymore and would look to turn it onto a media/backup server for music/pictures - and maybe documents/code. The laptop only has 40Gb of HD space but we can hook to it a USB external HD with an additional 80Gb. This is a very general question: - What OS should I put on it (more like, what flavor of Linux)? - What media/backup server software should I install on top of that? - How would you go about backing up to it? I need to back up computers on the same LAN, some have Windows, some OS X, some Linux. If you could point me to an all-in-one solution with a nice tutorial for non-sysadmin folks it would be greatly appreciated, thank you!!!
