• 4 - 7 second delay accessing Mysql across the network

  - by Kristiaan

  Hello, our company has recently purchased a new server with the intention of replacing our aging database server. its a full 64bit 2008 enterprise system, i have got the basic server setup and configured and then installed the 64bit version of mysql on the server, this has then been configured to match where possible our existing server as much as it can. however i have noticed that when it was swapped with the production database server our software systems had an increased delay accessing the mysql database this was anything beween 4 - 7 seconds. i have tried disabling TOE, IPv6 and a few other suggested soultions to this but so far cannot find out where this slowdown is coming from. replacing the server with the production one and the delay goes away. in terms of software and hardware the servers are not very identical at all due to one being windows 2003 std with a 32bit server and the new one being windows 2008 enterprise with a 64bit server. thanks Kris

• portal/forum for small companies to get technology help

  - by thomas

  I understand this is an open ended question and not quite sure how to add this to community wiki, if that is appropriate. I am doing a little research on where small companies would go on the internet to get answers for technology related questions. Could be around sales, servers, programming, etc. Clearly superuser.com, serverfault.com, and stackoverflow.com are excellent starting points. I am just wondering if anyone has heard of any others. Think a "facebook" that links technology providers with small companies to help answer questions and potentially provide/offer solutions. Thanks!

• How to recover from failed Mysql schema update, with replication?

  - by OmerGertel

  I have two MySQL servers configured with master-slave replication. Before we deploy a new application version we: 1) STOP SLAVE 2) Take a MySQL dump of the slave. However, if a mistake is done during the deployment of the new schema version (a table is dropped by mistake, for example), having the slave intact doesn't help. Our service is write-intensive, so we can't turn it back up until we have a master working. If we now load the mysql dump back into the master, it will take a long time during which our service remains down. What is the best-practice to recover from such a mistake? How can I setup the system so I can easily promote the slave, turn on our service and only then tend to the broken database? Mainly, I'm worried with re-syncing the slave and the master after changes are done on the slave.

• 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...

• What are the mandatory Linux kernel modules to run inside of ESXi

  - by Marcin

  I'm used to rolling my own kernels for servers, as it nicely minimizes the number of exploits (and the resulting patches) to take care of. In a traditional (bare metal) world, the whole process is about knowing what you have (hardware), and what you need (Ethernet, IPv4, iptables, etc.) In a virtualized environment, some things stay the same (still need Ethernet and IPv4), some things go away (power management), and then there are some new needs (vxnet3, or vmware-tools, even though that's compiled outside of the kernel). So my question mostly concerns itself with the last two categories: what can I remove completely, and what new stuff do I want? For example, what IO scheduler do I want, if all my disk operations are going through another filesystem/scheduler/cache to get to the virtual disk? Do I need hyper-threading enabled, or is the VM going to show them to me anyway as a CPU anyway? Do I need Large Receive Offload turned on, or is that something that the hypervisor's network drivers are going to do for me?

• memcached and IIS manager with windows 2008

  - by user64484

  I have memcached (c:\memcached) running on port 11211 and I have a problem configuring IIS manager I created a site in IIS manager binded to port 11211 and if I have memcached running and try and start the site it says "the process cant access the file because it is being used by another process" If I stop memcached and start the site in IIS (and enable directory browsing) I can access the directory structure http://localhost:11211 ok, if I then try and start memcached it errors with error 1053 "could not start the memcached server on local computer" I know I'm doing something fundamentally wrong here! just cannot figure out how I can use IIS and memcached together. [edit]I should add that I need other servers to be able to access memcached[/edit]

• Is there an apache module to slow down site scans?

  - by florin

  I am administering a few web servers. Each night, random hosts from the Internet are probing them for various vulnerabilities in php, phpadmin, horde, mysqladmin, etc. Is there a way (apache plugin?) to slow down the rate of attack? For SSH, I have a rate limiting rule on the firewall, which does not allow more than three connections per minute. But I don't want to rate limit all HTTP access, only the access that returns 404s. Is there such an apache module?

• Port 53 UDP Outgoing flood

  - by DanSpd

  Hello I am experiencing very huge problem. I have 4 computers in network, and from each a lot of data is being sent to ISP name servers.

I have antivirus (Avast) and malware scan (SpyBot) I know port 53 UDP is dns which resolves domain IP so its' needed. Also I have read that ISP name server might have been infected. So what is the best thing to do in this situation. Also sometimes internet starts to lag really because of port 53

• Logging off does not kill process in Windows Server 2003

  - by Suraj Chandran

  I have a Windows Server 2003(Enterprise, SP2). My understanding was that any process created by a user will be terminated when the user loggs off the account. But its not happening. I login via Administrator account. Start a simple java process and logoff. But the process is not killed. Is there any configuration for this or something? I am mostly a software programmer and not much in to servers and so I am stuck. I found out that while logging off, 1) Win32 is supposed to send a CTRL_LOGOFF_EVENT to all processes started by that user. 2) JVM is supposed to handle this event and terminate the VM. But I can't understand why my java process is not killed when i logoff. Any idea!!!

• Strange FTP issues - some files are not downloaded

  - by FractalizeR

  I have a machine, which cannot fetch some files from remote servers by FTP. Machine is powered by CentOS. I tested FTP on three files: 12.09.2012 21:21 166 007 ll091212.002 13.09.2012 11:32 23 040 ll091212.003 13.09.2012 11:50 61 313 ll091212.004 From them, I can always successfully download only one - ll091212.004. Two others are downloaded by about 90% (I can see them on disk) and then FTP transfer hangs without any error messages. I move files, copy them about the remote server - no luck. Another machine from the same subnet can download all three of them easily. I just don't know what's the reason of this.

• How to detect when a user copies files from a server over the network?

  - by Mr. Graves

  I have a few virtual servers + desktops that are used for shared development with remote users, including some consultants. Each user has an account with access to most aspects of the server. I don't want to prevent people from being productive, or track passwords or read emails, but I do want to know when and what files they copy from the virtual server or what they upload from the server to a remote site, and what if any applications they install. This will help make sure my IP is protected, that no one is installing tools they shouldn't, and that things are licensed appropriately. What is the simplest way to do this? In order of importance I would say detecting file transfers off the machine to be most critical. Thanks

• Adding a MySQL StoredProcedure causes not responding state

  - by Omie

  Hello I'm on Windows 7 ultimate 32bit + xampp 1.7.2 [MySQL v5.1.37] This is my stored procedure : delimiter // CREATE PROCEDURE updatePoints(IN parentid INT(5),IN userid INT(5)) DECLARE chpoints INT(5); BEGIN SELECT points INTO chpoints FROM quiz_challenges WHERE id = parentid; UPDATE quiz_users SET points = points + chpoints WHERE forumid=userid; END; // delimiter ; At first it was showing error 1064 while creating stored procedure. I added delimiters part and when I tried running the query from phpmyadmin, Firefox went into not responding state. After that I started Internet Explorer and tried opening my pages which use the same database, it worked fine. However, I tried opening phpmyadmin and IE went into not responding state as well. I restarted both servers. Later restarted PC. Tried again but its same behavior. So whats wrong with this tiny little code ? Am I missing something which might be causing infinite loop ? Thanks

• How to ignore query parameters in web cache?

  - by eduardocereto

  Google Analytics use some query parameters to identify campaigns and to do cookie control. This is all handled by javascript code. Take a look at the following example: http://www.example.com/?utm_source=newsletter&utm_medium=email&utm_ter m=October%2B2008&utm_campaign=promotion This will set cookies via JavaScript with the right campaign origin. This query parameters can have multiple and sometimes random values. Since they are used as cache hash keys the cache performance is heavily degraded in some scenarios. I suppose there's a not so hard configuration on cache servers to just ignore all query parameters or specific query parameters. Am I right? Does anyone know how hard is it in popular web cache solutions, to create ? I'm not interested in a specific web cache solution. It would be great to hear about the one you use.

• How to repair unbootable Fedora install

  - by Cerin

  How do you repair/reinstall Fedora without deleting any existing partitions or data? I was attempting to upgrade some old Fedora 13 servers to 17, following the instructions in the wiki. After the 14-15 upgrade, rebooting resulted in the output: Dropping to debug shell. sh: can't access tty; job control turned off dracut:/# Running dmesg also shows: dracut Warning: No root device "block:/dev/mapper/VolGroup-lv_root" found Googling shows this error is typically related to some weird RAID issues, but my server is a virtual machine not using any RAID. Using a rescue CD, I can chroot /mnt/sysimage, and all packages and data still seems to be there. How do I make the system bootable again?

• Reccomendation for tuning 100's of Sql Databases

  - by wayne

  Hi, I'm running several sql servers, each running a few hundred multi gig databases for customers. They are all setup homogeneously as far as the schemas are concerned, however customer usages of the data differ quite alot from database to database. What would be the best way to auto-index / profile / tune this large amount of databases? As there are atleast 600 or more catalogs i cant have someone manually profile, and index as required by each databases usage patterns. I'm currently running SQL 2005 but will be moving to 2008, so solutions that work with either are fine!

• Trying to test Domain Collapsing / Consoldiation validity for SEO purposes

  - by Roy Rico

  At work, we're trying to determine the effectiveness of domain collapsing for SEO purposes. Our current structure is to have multiple web apps served from different servers, such as PUBLIC URLS - directly accessed by users www1.somecompany.com/webapp1 www2.somecompany.com/webapp2 www3.somecompany.com/webapp3 I'm proposing to put an Apache proxy in front of these applications that will mask the different domains and route the requests to proper server PUBLIC URL--------routed/forwarded to-----PRIVATE URL www.somecompany.com/webapp1 <-----> www1.somecompany.com/webapp1 www.somecompany.com/webapp2 <-----> www2.somecompany.com/webapp2 www.somecompany.com/webapp3 <-----> www3.somecompany.com/webapp3 In terms of SEO/page rank value, does this help?

• Options for PCI-DSS on AWS - file integrity monitoring and intrusion detection

  - by Brill Pappin

  I need to deploy some file integrity monitoring and intrusion detections software on AWS instances. I really wanted to use OSSEC, however it does not work well in an environment where servers can auto deploy and shut down based on load, because it requires server managed keys to be generated. Including the agent in the AMI will not allow monitoring as soon as it comes up because of that. There are many options out there, and several are listed in other posts on this site, however none that I've seen so far deal with the unique problems inherent in AWS or cloud based deployments in general. Can anyone point me at some products, preferably open source, that we might use to cover those portions of PCI DSS that require this software? Has anyone else achieved this on AWS?

• Windows 7 connect to Lion file sharing

  - by McKvack

  Trying to access my Mac from a Windows 7 computer, I fail with the infamous error 86 incorrect password. Now this appears to be a well-known problem with countless threads on the internet giving as many "solutions" as there are discussion threads about it (mostly ranging from installing third-party commercial samba servers, to switching to some other protocol, to compiling a plain-vanilla Samba installation - the latter which I will probably do when I give up this :) ) I am stubborn, and I believe there must be some problem here that can be solved or worked around, but there is surprisingly little detail about this problem. It appears to have something to do with a mismatch of authentication methods. Trying to run samba in debug mode: sudo /usr/sbin/smbd -debug -stdout gets me this output when trying to access it from Win 7 ... smb1_dispatch_one [smb_dispatch.cpp:377] dispatching SMB_COM_SESSION_SETUP_ANDX smb1_dispatch_session_setup [session_setup.cpp:261] FIXME erase existing sessions log_gss_error [gssapi_mechanism.cpp:97] gssapi: gss-code: Miscellaneous failure (see text) log_gss_error [gssapi_mechanism.cpp:113] gssapi: mech-code: unknown mech-code 22 for mech unknown What is the problem here, and how do I fix it?

• Upgrading drives on a MD3000

  - by Anonymouse

  Hello, Our MD3000 array is getting full as our databases are growing and we need more spaces. Currently, we use a MD3000 with a two-servers Windows 2003 cluster and 15x 73GB SAS drives. Disk groups are configured in RAID1 of two drives. The approach we are currently investigating is simply swapping the existing SAS drives with bigger ones (300GB instead of 73GB), one at a time, and let each RAID1 array rebuilt. Is it a good approach? Will we be able to resize the array afterwards? Will we be able to resize the partitions afterwards? Can the Dell M3000 Management software do it or will we have to bring the server offline and use some partition software to do it? Thanks in advance.

• What happens with the Guest OS's on ESXi in the event of a power failure?

  - by Jeremy Holovacs

  Many small businesses would prefer to let their server drop on power failure than to pay even $100 for a cheap UPS. It's often difficult to convince them of the value of something like that; it's why they like ESXi. It's free, they can save a lot of cash by putting a bunch of linux servers on one machine, and then I get paid. :) If the ESXi server experiences a power outage, it is set to come back on automatically when power is restored. What happens with the guest OS's? Ideally I would like them to all come online again as well, assuming they were on when power was lost, but I see no option for choosing this. I don't want to yank power to the system just to try it out, of course. I'm sure someone knows what happens by default, and perhaps how to make my system to work as I would wish.

• Hosting 3 domains on 3 PC (1 domain per PC) with only 1 static IP address

  - by StealthRT

  Hey all i am trying to figure this out here. I have 3 PC's that are hooked into my router which i have a static IP for. I am currently hosting a web site (ex: blah1.com) on the 1st PC but have yet to connect PC 2 and 3 up to the network. That one PC thats online is using port 77. I direct all 80 traffic to port 77 using that servers IP address (192.168.x.xxx) My question is, how can i direct traffic for my other 2 domains (ex: blah2.com and blah3.com) to the 2 individual PC's (ip's) as i already am doing with the 1st PC if i can only use one port 80 to direct taffic to the website in?

• What is the easiest way to get XtraDB for MySQL running on CentOS 5

  - by Jeremy Clarke

  I'm having a lot of issues with a dedicated MySQL server and it seems like upgrading to the XtraDB version of InnoDB will probably have a positive effect, but I'm hesitant to get involved with it since I am not really a sysadmin and prefer to stick with things that start with "yum update". What is the easiest way to get XtraDB installed? Should I use the Percona server? MariaDB? OurDelta? Is there a way to avoid using custom RPMs and sticking to a repo instead? The current yum version of MySQL is 5.0.xx, whereas a lot of the alternate MySQL builds are based on 5.1.xx. How does this factor in? Do I need to figure out 5.1 on CentOS before working on getting XtraDB in? For bonus points: Do I need to seriously test XtraDB with my server before implementing it, or is it relatively safe to have the brief downtime for switching servers followed by putting the site back online with XtraDB?

• Getting Pango-WARNING: Invalid UTF-8 string passed to pango_layout_set_text()

  - by geerlingguy

  About three days ago, I noticed the exim mailqueue started filling up on one of my servers, and upon inspecting some of the emails using # exim -Mvb $ID, I noticed they were being sent to some system email address (which is not a real address), and the body of the messages were as follows: (process:8259): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text() I'm wondering what could be causing this strange issue, as I've never heard of 'pango' at all... I've never seen that function used in my lifetime! It seems the process id (PID) is for an apache process, though, as the pids are always gone by the time I use # ps -aux to look them up. Edit: Whoops! Forgot to include the subject - looks like it's actually munin-cron that's bringing up the issue: Subject: Cron /usr/bin/munin-cron --force-root

• What is the Best Free Linux Gateway

  - by rockinthesixstring

  I'm looking at moving away from using my DIR-825 as a gateway and moving into a Linux box to do it all for me. I've found IPCop, but I'm looking for something with a little more power. My main goal is basically to be able to point different external domain names to different internal servers. backup.example.com - 192.168.0.5 home.example.com - 192.168.0.1 I host my DNS on my own dedicated server (windows), so I don't know much about doing the gateway thing in my home (my hosting provider does it all for me). Do any of you know of any free Linux Distros that can accomplish what I'm looking for?

• need help upgrading small business wifi network

  - by Henry Jackson

  Our small business currently has 3 wireless access points around the building, each with their own SSID. Security is done with WEP (ick) and MAC address filtering (double ick). We are trying to reconfigure the setup, with these goals: wifi roaming between the access points user-based authentication that isn't as annoying as MAC address filtering. 1) The entire building is hardwired with ethernet, so I assume it should be easy to set up the routers to act as one big network, but I can't figure out how. Can someone point me in the right direction? The routers are consumer-grade linksys routers, is it possible to do this without getting new hardware? 2) For security, we will probably upgrade to WPA2, and I'm thinking of using the Enterprise version so that users can log in with a username, instead of having a single key (so if an employee leaves or something, their access can be removed). We have several on-site Windows servers, can one of them be set up as a RADIUS server, or is that best left to a dedicated machine (again, using existing hardware is good).
