• How to test TempDB performance?

  - by Matt Penner

  I'm getting some conflicting advice on how to best configure our SQL storage with our current SAN. I would like to do some of my own performance testing with a few different configurations. I looked at using SQLIOSim but it doesn't seem to simulate TempDB. Can anyone recommend a way to test data, log and TempDB performance? What about using a SQL profiler trace file from our production system? How would I use This to run against my test server? Thanks, Matt

• PHP crashing on occasion - APC error?

  - by papanel

  Any thoughts on this? We've had this happen twice recently. Basically, every page throws a fatal error, fixed by an apache restart. Here's what's in the log, repeated over and over. [Tue Apr 13 15:18:12 2010] [error] [client 10.0.0.2] PHP Fatal error: Internal Zend error - Missing class information for in /www/sites/ep/vogoo/items.php on line 31 [Tue Apr 13 15:18:12 2010] [error] [client 10.0.0.2] PHP Fatal error: Internal Zend error - Missing class information for in /www/sites/ep/vogoo/items.php on line 31 [Tue Apr 13 15:18:13 2010] [error] [client 10.0.0.2] PHP Fatal error: Internal Zend error - Missing class information for in /www/sites/ep/vogoo/items.php on line 31 Looking around, this may be an issue with APC? http://pecl.php.net/bugs/bug.php?id=16120&edit=1 (We're running 3.0.19, which shows as latest stable on pecl.) Thoughts? I increased the amount of memory apc uses, but the problem just happened again.

• Only one user at once through remote

  - by Lazlo

  Hi, This is probably an easy question for anyone used to servers, and I know I once managed to do it, but I don't remember how. I purchased a VPS and am able to connect correctly as Administrator, and can start, let's say, MyServer.exe. Problem is, if I connect as Administrator on another device, this process is still there, but I can't see it. What I want to do is limit the connection per user to 1, and disconnect others when one logs in. I know there was a simpler term, a simple way, but I truly don't remember. And since I'm not used to the vocabulary of servers, I couldn't find it in the S/F questions. Thanks in advance!

• allowing sudo to delete certain files

  - by chandank

  I would like to allow to delete certain files in /tmp directory to sudo users. I have added the Allow_Cmnd /usr/sbin/userdel for sudo users but this does not delete all /tmp files associated with the user. So how shall I tweak the sudoers to allow them to delete certain files in /tmp directory only. I googled a bit but learned that regex may be be application at this. I tried couple of tweaks but its not working for me. I would like the users to have ability to execute command such as find /tmp -uid 10002 | grep joeuser | xargs rm -rf

• Paypal Express Checkout api credentials - How to store them properly?

  - by Sequence

  I've been searching the internet and I've come up with a lot of answers of how to store paypal API credentials(Used in Paypal Express Checkout.) They say to hash the credentials using salt. But what I don't understand is how and where to store the salt. If they get access to the salt, can't they just un-hash the credentials? That doesn't seem very secure to me. They say not to hard-code the API credentials, but any other way still seems really vulnerable. Thanks for taking the time to look at my questions. I'd really appreciate help.

• Development Server Blocked Only from Home

  - by theonlylos

  Recently I've been having an issue with my CentOS 6 test server running Apache and Webmin running on port 10000 where when I try accessing any part of the server - SSH/FTP and even my domains (I have two - both keep getting timeout errors) when I try accessing from any computer on my home network. However when I access via tethering or via my office networks everything loads fine. While the firewall is the first issue at mind, my router never was set to block any special ports, and even after adding port 10000 as a specific exception I'm having no luck. Also, I doubt this is an IP blacklisting issue because I have websites on other servers using CloudFlare for security and I haven't gotten any warnings. Any assistance is greatly apprecaiated. UPDATE: Just some extra details about the issue: My ISP to my knowledge only blocks off ports 25 and 80 for residential users to prevent them from running web servers - however this issue has only come up a day or two ago, before that I was using the server successfully for months. Also the server is not physically located in any of my workspaces - it's a VPS housed in a datacenter

• When you add a new node to a cluster, what do you do to the default services?

  - by Tom

  Everytime I acquire a new server or reload an existing server (CentOS 6.X) I have to decide what services to leave running in chkconfig. It seems the datacenter staff aren't using a single edition of CentOS and sometimes the default services running are different. I'm always inclined to turn off every service I've never heard of but then I think, if it's not broken don't fix it. How do you deal with the default services in a new installation?

• Dynamic nginx domain root path based on hostname?

  - by Xeoncross

  I am trying to setup my development nginx/PHP server with a basic master/catch-all vhost config so that I can created unlimited ___.framework.loc domains as needed. server { listen 80; index index.html index.htm index.php; # Test 1 server_name ~^(.+)\.frameworks\.loc$; set $file_path $1; root /var/www/frameworks/$file_path/public; include /etc/nginx/php.conf; } However, nginx responds with a 404 error for this setup. I know nginx and PHP are working and have permission because the localhost config I'm using works fine. server { listen 80 default; server_name localhost; root /var/www/localhost; index index.html index.htm index.php; include /etc/nginx/php.conf; } What should I be checking to find the problem? Here is a copy of that php.conf they are both loading. location / { try_files $uri $uri/ /index.php$is_args$args; } location ~ \.php$ { try_files $uri =404; include fastcgi_params; fastcgi_index index.php; # Keep these parameters for compatibility with old PHP scripts using them. fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; # Some default config fastcgi_connect_timeout 20; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on; fastcgi_ignore_client_abort off; fastcgi_pass 127.0.0.1:9000; }

• How to enable synergy 24800 (or some other port) through firewalld

  - by ndasusers

  After upgrading to Fedora 18, Synergy, the keyboard sharing system was blocked by default. The culprit was firewalld, which happily ignored my previous settings made in the Fedora GUI, backed by iptables. ~]$ ps aux | grep firewall root 3222 0.0 1.2 22364 12336 ? Ss 18:17 0:00 /usr/bin/python /usr/sbin/firewalld --nofork david 3783 0.0 0.0 4788 808 pts/0 S+ 20:08 0:00 grep --color=auto firewall ~]$ Ok, so how to get around this? I did sudo killall firealld for several weeks, but that got annoying every time I rebooted. It was time to look for some clues. There were several one liners, but they did not work for me. They kept spitting out the help text. For example: ~]$ sudo firewall-cmd --zone=internal --add --port=24800/tcp [sudo] password for auser: option --add not a unique prefix Also, posts that clamied this command worked also stated it was temporary, unable to survive a reboot. I ended up adding a file to the config directory to be loaded in on boot. Would anyone be able to have a look at that and see if I missed something? Though synergy works, when I run the list command, I get no result: ~]$ sudo firewall-cmd --zone=internal --list-services ipp-client mdns dhcpv6-client ssh samba-client ~]$ sudo firewall-cmd --zone=internal --list-ports ~]$

• 32bit vs 64bit guest VM and RAM usage

  - by sims

  Why does a 32bit domU (Xen guest VM) use less RAM than a 64bit? Notes: The same software complied for a different arch(AMD64 vs. 686). Obviously this is Linux or BSD or something easily ported. Maybe this is also a good one for SO. I've read this is so. I can guess why, but I'd like to hear everyone's comments.

• Increasing file descriptor limit on Debian does not work! Help!

  - by Aco

  I am running Debian 6 and I am trying to increase the file descriptor limit but it does not want to work. This is what I have done: I edited /etc/sysctl.conf by adding fs.file-max = 64000 at the end and applied the changes using sysctl -p. I then edited /etc/security/limits.conf and added the following lines: * soft nofile 64000 and * hard nofile 64000. Now when I execute ulimit -Hn and ulimit -Sn I still see 1024. I rebooted the server and I still get the same result. What have I failed to do?

• Setting alias for DynDNS domain

  - by metalball

  Hey all, I've created DynDNS domain for testing my local sites, and i'm having trouble with pointing to root domain. From my registrar (GoDaddy) I've created a CNAME for www to point my example.dyndns.com so going to url www.example.com I'm reaching my site. But if I'm going to example.com I'm reaching to the IP of the A record. I can't set the IP for the A record to be my IP because I have dynamic IP, and it changes constatly, and I can't point the A record to domain, only IP. When trying to create CNAME record @ to point example.dyndns.com I'm getting error "A record of a different type exists for the hostname @, could not create CNAME" The only record using the '@' host are NS record, which I can't delete, and when tried to set another NS record with @ point to example.dyndns.com, I've lost connection to my site :) So what can I do to get example.com url reach my site? Thanx!

• How do I speed up load times on roaming profiles with Active Directory?

  - by user65712

  I've done some reading and apparently the main obstacle to fast remote profile syncing is that Samba takes a long time to transfer lots of little files like cookies. After reading Roaming Profiles: Best Practices , I plan to use Folder Redirection, but I want my users to be able to login as rapidly as possible, even if it means that their data is still coming in when they reach their desktop. Is there a way to do this with GPO or a third party add-on that can load user profile data faster/speed up the login process for users?

• How to fix subfolders IIS7 functionality?

  - by Amr ElGarhy

  I have a problem in my sharing hosting that all websites in subfolders, their URL appear like this: http://amrelgarhy.com/amrelgarhy/ I sent to godaddy, and they sent me that its because of IIS7 and they can't solve, any one can tell me how to fix that? Here what i sent to godaddy and their reply: "as i saw before on this page http://www.godaddy.com/gdshop/hosting/shared.asp?ci=9009 compare windows plans, "Multiple Web sites: unlimited" so i have the right to run more than one website inside my hosting. But what i am facing now that i can't make more than website as a primary website. I have igurr.com as a primary website, i want to make others as primary because: I am facing a problem that all home pages for the other websites "which physically in sub folders" are like that "http://amrelgarhy.com/amrelgarhy/" the URL + the folder name and that what i don't want." GODADDY "Thank you for contacting Hosting Support. The behavior you are describing is standard for IIS 7.0 accounts. All alias domains in this environment will append the foldername their located in. I.E. a an alias domain www.coolexample.com pointed to the '/example' directory will display in a browser as "www.coolexample.com/example". This is due to the way IIS 7.0 handles virtual directories. Unfortunately we do not have any direct work around for this. We apologize for any inconvenience this may cause. "

• "tasksel: aptitude failed (100)" installing LAMP on Ubuntu (vagrant)

  - by John Mee

  vagrant@precise64:~$ sudo tasksel install lamp-server tasksel: aptitude failed (100) I'm hoping to get a LAMP server from a clean install of ubuntu. All the googles suggest tasksel, which going into a pretty ascii gui, downloads stuff, then dies with this message. I'm guessing I should try doing it via apt-get of the individual packages but seems a fair chance somebody else is going to search for this error message and want the right answer.

• How to stop a random ramp in FCGI Processes Killing the server

  - by Andy Main

  So got the below earlier to day... Around that time the logs show a ramp in processes(600) and associated memory (1.2g), cpu usage load average (80) untill the server gave out. Server had to be hard reset by host as there was no ssh or plesk panel access. Fast CGI is configured as below and is setup for one high use site. As I understand it FcgidMaxProcesses 20 should protect against what happen but has not. I've read many forums with differing answers and references to many different fcgi directives, but have found nothing conclusive. Any one got some definitive answers on how to stop this sort of server process ramping and subsequent server failure? If you need more info let me know.

• Authenticating Linked Servers - SQL Server 8 to SQL Server 10

  - by jp2code

  We have an old SQL Server 2000 database that has to be kept because it is needed on our manufacturing machines. It also maintains our employee records, since they are needed on these machines for employee logins. We also have a newer SQL Server 10 database (I think this is 2008, but I'm not sure) that we are using for newer development. I have recently learned (i.e. today) that I can link the two servers. This would allow me to access the employee tables in the newer server. Following the SF post SQL Server to SQL Server Linked Server Setup, I tried adding the link. In our SQL Server 2000 machine, I got this error: Similarly, on our SQL Server 10 machine, I got this error: The messages, though worded different, probably say the same thing: I need to authenticate, somehow. We have an Active Directory, but it is on yet another server. What, exactly, should be done here? A guy HERE<< said to check the Security settings, but did not say what else to do. Both servers are set to SQL Server and Windows Authentication mode. Now what?

• Accessing guests on virtual network when connected to host via PPTP

  - by Viktor Elofsson

  I'm setting up a development machine which runs Ubuntu 12.04 and KVM for virtualization. I have a guest running Ubuntu 12.04 which can be accessed from the host via its IP address which is assigned by libvirt. The guest can also access the internet, no problem there. However, now I want to setup PPTP so I can connect to the host (from my workstation running Windows 7) and directly access guests without relying on SSH port forwarding. I can connect from my W7-machine to the host (PPTP), but I cannot access any virtual machines (which are accessable from the host directly).

It's probably something trivial I'm missing but I can't for the life of me figure out what it is. So I'm turning to you, serverfault.

• Auto-Attach EBS-volume to a New Spot Instance?

  - by Jeff

  I am experimenting with EC2 spot instances, and am needing some data to be retained between terminations. Now as I understand it, when the current price goes above my max. bid, it will be automatically terminated. I assume any init scripts I have will be run on shutdown so I can push data off to the EBS before unmounting. My question is, how can I automatically mount the same EBS volume on the new spot instance once the price goes down, since it won't have any of my init scripts that I would've loaded onto the root volume the first time? Do I have to create a custom AMI, or is there some other way to achieve this?

• Setting lusca and dansguardian iptables on Ubuntu 12.04 to prevent loop

  - by Heri YT

  I have a server with ubuntu 12:04 operating system, which runs as a proxy cache server lusca and DansGuardian as well as internet content filter. With the following composition: the client browser - lusca - DansGuardian - internet. And all this running only on one machine only, the following is a partial configuration on my server lusca: http_port 3128 transparent cache_peer 192.168.0.1 parent 8080 0 no-query no-digest no-netdb-exchange default which is also only found on the DansGuardian default settings namely: filterip="blank" filterport=8080 proxyip=192.168.0.1 proxyport=3128 The question is: Can all goes well? By simply relying on one machine only? What causes the "WARNING: Forwarding loop detected for:"? is not problematic if we leave? How to solve "WARNING: Forwarding loop detected for:" found in / var / log / lusca / cache.log Thank you.

• Shell Script Launching Child Processes

  - by Matt James

  Disclaimer: I'm totally new to shell scripting, but have quite a bit of experience in other languages like PHP and Obj-C. I'm writing my first daemon script. Here are the goals: I want it to run in the background I want it to be triggered by an init.d script that includes start/stop/restart commands I want each process in a loop to trigger its own subprocess. When the parent process kicked off by the init.d script is killed, I want the subprocesses to die as well. Essentially, I'm looking for the same kind of behavior that appears to be very common among software like apache, spamd, dovecot, etc. But, based on my research, I haven't found a single, simple answer as to how this kind of thing is achieved. Any help is greatly appreciated.
