  • Unable to enable InnoDB in mySQL on Ubuntu 10.04

    - by spowers
    I am trying to enable InnDB on my linux server. I have installed Ubuntu 10.04 JeOS on an ESX server. I then installed mySQL and tomcat using aptitude. However when I use SHOW ENGINES; in mySQL it does not appear that InnoDB was installed. I then tried following the directions in the documentation. http://dev.mysql.com/doc/refman/5.1/en/innodb.html However I get the following when trying to enable a plugin: ERROR 1123 (HY000): Can't initialize function 'InnoDB'; Plugin initialization function failed. I would appreciate some advice as to how to approach this problem.

  • How to get IIS6 to respond to the OPTIONS verb?

    - by puffpio
    I have a WCF webservice hosted in IIS6 that another site will POST to in a cross domain manner using jquery. Because it is a cross domain POST, the browser first sends an OPTIONS verb with Access-Control-Request-Method: POST However, IIS6 does not respond back with anything. Is this something that I need to handle at a web service level or something at the IIS level?

  • copying folder and file permissions from one user to another after switching domains [closed]

    - by emptyspaces
    Please excuse the title, this was the best way I could think to describe this scenario without an entire paragraph. I am using C#. Currently I have a file server running windows server 2003 setup on a domain, we will call this oldDomain, and I have about 500 user accounts with various permissions on this server. Because of restrictions out of my control we are abandoning this domain and using another one that is more dominant within the organization, we will call this newDomain. All of the users that have accounts on oldDomain also have accounts on newDomain, but the usernames are completely different and there is no link between the two. What I am hoping to do is generate a list of all user accounts and this appropriate sid's from AD on the oldDomain, I already have this part done using dsquery and dsget. Then I will have someone go through and match all of the accounts from oldDomain to the correct username on newDomain. Ultimately leaving me with a list of sids from oldDomain and the appropriate username from newDomain. Now I am hoping to copy the file and folder permissions from the old user from oldDomain to the new user on newDomain once I join the server to newDomain. Can anyone tell me what the best way to copy permissions from the sid to the user on newDomain? There are a bunch of articles out there about copying permissions from user a to user b but I wanted to check and see what the recommended practice is here since there are a ton of directories.

  • litespeed issue with content-type

    - by sandeep.s85
    I am running magento with litespeed. The problem I am facing is that ajax call is being made of which header is set as x-json, but lightspeed is setting another header of text/html content type I've checked that page with apache and everything is working fine.

  • Finding latest successful logins and failed attempts to a CentOS server

    - by ahmad
    I'm looking for a log file or any service to report the latest login attempts which have failed due to username/password miss match. Is there such utility available for CentOS? (built-in is preferred) My second question, and more generally, I need a log file of penetration attempts to my server. Ideally, this log should contain all attempts including logins, httpd activities, and other conventional open ports.

  • What does a DHCP-client consider to be the "best" answer?

    - by Nils
    We have training rooms where normally Windows XP is installed (via PXE). The "normal" DNS/DHCP infrastructure are Windows-Servers. The training room has its own VLAN (different from the Windows servers), so there is most propably an IP helper for DHCP requests active on the Cisco router where all PCs from that room are connected to. Now we wanted to convert some of the PCs to Linux instead. The idea was: Put our own Laptop with a DHCP server into the VLAN of the room and override the "normal" DHCP response. The idea was that this should work, since a directly attached DHCP server in that VLAN should have a faster response-time than the "normal" DHCP server located some hops away from that VLAN. It turned out that this did not work. We had to manually release the lease on the original DHCP server to get it working. On the Laptop we did see the client requesting the IP and "our" dhcp was sending NACKs to the Windows IP request, before that we did offer our own response. Old Question: Why did this not work out as expected? What is making the PC regain its old lease? Update 2012-08-08: The regain-issue has been explained in the DHCP-RFC. Now this explains why the PC regains its old lease. Now we do release the IP from the Windows-DHCP-server before giving it another try. Again - the Windows-DHCP-server wins. I suspect that there is some algorithm for the dhcp-client which determines the "best" dhcp-answer for the client. The new question is: How does the client choose the "best" answer?

  • Trying to install wordpress inside rails app with nginx and fastcgi

    - by pinouchon
    I have a rails app (let's call it myapp) running at www.myapp.com. I want to add a wordpress blog at www.myapp.com/blog. The webserver for the rails app is thin (see the upstream block). The wordpress runs with php-fastcgi. The rails app works fine. My problem is the following: in /home/myapp/myapp/log/error.log error I get: 2013/06/24 10:19:40 [error] 26066#0: *4 connect() failed (111: Connection refused) while connecti\ ng to upstream, client: xx.xx.138.20, server: www.myapp.com, request: "GET /blog/ HTTP/1.1", \ upstream: "fastcgi://127.0.0.1:9000", host: "www.myapp.com" Here is the nginx conf file: upstream myapp { server unix:/tmp/thin_myapp.0.sock; server unix:/tmp/thin_myapp.1.sock; server unix:/tmp/thin_myapp2.sock; } server { listen 80; server_name www.myapp.com; client_max_body_size 20M; access_log /home/myapp/myapp/log/access.log; error_log /home/myapp/myapp/log/error.log error; root /home/myapp/myapp/public; index index.html; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; # Index HTML Files if (-f $document_root/cache/$uri/index.html) { rewrite (.*) /cache/$1/index.html break; } if (!-f $request_filename) { proxy_pass http://myapp; break; } # try_files /system/maintenance.html $uri $uri/index.html $uri.html @ruby; } location /blog/ { root /var/www/wordpress; fastcgi_index index.php; if (!-e $request_filename) { rewrite ^(.*)$ /blog/index.php?q=$1 last; } include /etc/nginx/fastcgi_params; fastcgi_param SCRIPT_FILENAME /var/www/wordpress$fastcgi_script_name; fastcgi_pass localhost:9000; # port to FastCGI } } Any ideas why that doesn't work ?

  • Database types for customer analytics

    - by Drewdavid
    I am exploring a paid solution to start providing better embedded, dashboard-style analytics information to our website customers/account holders, but would like to also offer an in-house development option to our team. The more equipped I am with specifics (such as the subject of this question), the better the adoption rate from the team (or so I have found), regardless of the path we choose Would anyone care to summarize a couple of options for a fast and scalable database type through which we would provide the following: • Daily pageviews to a users account pages (users have between 1 and 1000 pages) • Some calculated/compounded metrics (such as conversion rate, i.e. certain page type viewed to contact form thank you page ratio) • We have about 1,500 members (will need room to grow); the number of concurrently logged in users will for the question's sake be 50 I ask because our developer has balked at providing this level of "over time" granularity (i.e. daily) due to the number of space it would take up in a MYSQL database To avoid a downvote I have asked specifically for more than one option, realizing that different people will have different solutions. I will make amendments to my question if so guided by answering parties Thank you for sharing your valued answers :)

  • PHP-FPM for nginx on debian

    - by Jelko
    What is the preferred/recommended way of installing php-fpm on debian for use with nginx? I read about a "php5-fpm" package everywhere, but it's not available in the official debian repos any more. The PHP-FPM website (http://php-fpm.org/download/) says that fpm is now included with the php core. Is it enough to install "php5-common" then? Where are the config files, though? Other people recommend to install the current version of php and php-fpm from dotdeb.org. The versions provided there are generally more up to date. But is it secure? Is this a good repo to use in a production environment? I would appreciate any advice.

  • Get IP or MAC addresses of Windows Multipoint Server 2012 stations?

    - by user1454265
    Is it possible to programmatically retrieve the IP or MAC address of a station assigned to a Windows MultiPoint Server 2012 host, using PowerShell or any other .NET or Windows API? Background: I'm developing a application to help set up USB-over-Ethernet zero clients in a WMS 2012 setup, bridging the PowerShell "WmsCmdlets" module (Microsoft.WindowsServerSolutions.MultipointServer.PowerShell.Commands.Library.WmsStation) and a third-party vendor API for configuring zero client IP address, etc. So far, I do not know any means of matching up the "stations" of the WmsCmdlets with the zero client objects in the vendor's API. Finding out the IP or MAC associated with a WMS station would do nicely, since I have this on the zero client API side. However, I haven't found any information I could use in the PowerShell WmsCmdlets module, such as Get-WmsStation which returns the following: Id : 1 Name : <my station name> IsAutoLogOn : False IsSplit : False CollabId : 0 RemoteConnectionServerName : VirtualMachineName : VirtualMachineId : AutoLogOnUserName : AutoLogOnPassword : DeviceTypes : {DT_Mouse, DT_Keyboard, DT_Audio, DT_MassStorage...} DeviceCounts : {2, 2, 0, 0...} ComputerName : <my WMS host server name> SessionId : 4294967295 SessionHostServer : <my WMS host server name>

  • Resolving CloudFlare DNS related mail delivery problems

    - by Andy Castles
    I recently started using CloudFlare and am having a few teething problems. Our domain is netlanguages.com and while we have a lot of sub-domains listen, we are currently only trialling a few of the servers through the CloudFlare CDN (for example, www.netlanguages.com is enabled for CDN, netlanguages.com is not). The actual CDN service seems to be reliable, but the problem that we are having is with DNS, and specifically with mail delivery. The background is that we have contact forms on our web site which use PHP mail() to send the details to end-users' email addresses, with the "from" address of the messages being [email protected] which is a valid address on our mail server. Most of the mails are arriving correctly, but a few specific people are not receiving them. The webserver uses qmail to deliver the messages, and the qmail log files show us some of the errors that the receiving mail servers return when they reject the mail delivery attempt. Two examples: Connected to 94.100.176.20 but sender was rejected./Remote host said: 421 DNS problem (interdominios.netlanguages.com). Try again later Connected to 213.186.33.29 but sender was rejected./Remote host said: 451 DNS temporary failure (#4.3.0) From what I can tell, the receiving SMTP server is doing a DNS lookup of some description on either the host of the "from" email address (netlanguages.com) or the server name given in the EHLO command of the SMTP conversation (in the first example above, interdominios.netlanguages.com), both of which should resolve to non-CloudFlare IP addresses. I've read that the CloudFlare DNS service is very reliable and fast but both of the problems above seem to point to a problem with remote servers unable to do DNS lookups. I should also point out that we changed our DNS to CloudFlare on 6th Feb, and since then started experiencing these mail delivery problems. On 22nd Feb we moved our DNS away from CloudFlare to see if the issues were related to CloudFlare and after a few hours delivery began to work. Then on 26th Feb I moved the DNS back to CloudFlare again and delivery problems started again. The issues definitely seems to be related to DNS, but I don't know if it's a configuration issue, or something else. Finally, I should say that our two DNS MX records point to non-CDN A record IP addresses, interdominios.netlanguages.com (the web and qmail server) also points to a non-CDN A record IP address. Does anyone know what the problem could be here? Any light you can shed on this will be most appreciated. Many thanks, Andy

  • IIS7 - Web Deployment Tool - SetParam/SetParamFile to set http and https bindings + Cert

    - by Andras Zoltan
    Hi, we're currently using the MS Web Deployment Tool to sync a live website and some WebServices from a staging box to two live servers. The staging box hosts the site on any IP on port 17000, whereas the two live servers are load-balanced and have a different IP for each of them. At present, I generate two separate packages for deployment - one for each machine - using the sync operation and specifying a DestinationBinding parameter as follows: msdeploy -verb:sync -source:WebServer,computerName=localhost -dest:package="machinename.zip" -setParam:type="DestinationBinding",scope="SiteName",value="ip_address:port:". (Split across multiple lines to make it easier to read!) I run this twice, with a different target filename and ip address for each of the two machines. When it comes to deployment, I simply do a sync from each package to its respective live site. I know, I know - I should be able to do it by generating one parameterised package and then perhaps using the SetParamFile switch for each of the two Servers - believe me I'd like to, but the documentation on doing this is frankly non-existent. Now I need to configure and deploy both HTTP and HTTPS binding for this site; including also the ssl cert that is to be used. I've added an SSL binding for the site on the staging box - which uses a development cert (which will need to be replaced - or should the staging box be using the live cert?), and now the above command line has the effect of replacing the target IP on both http and https entries. It appears that I cannot specify multiple bindings plus the cert information in the DestinationBinding value in the -setParam above, so anyone know how would I go about doing this? Any help greatly appreciated.

  • Ask a DNS server what sites it hosts - and how to possibly prevent misuse

    - by Exit
    I've got a server which I host my company website as well as some of my clients. I noticed a domain which I created, but never used, was being attacked by a poke and hope hacker. I imagine that the hacker collected the domain from either hitting my DNS server and requesting what domains are hosted. So, in the interest of prevention and better server management, how would I ask my own DNS server (Linux CentOS 4) what sites are being hosted on it? Also, is there a way to prevent these types of attacks by hiding this information? I would assume that DNS servers would need to keep some information public, but I'm not sure if there is something that most hosts do to help prevent these bandwidth wasting poke and hope attacks. Thanks in advance.

  • Remove SID with ICACLS

    - by chris
    I am trying to remove an obsolete SID (the account was apparently deleted). I've tried to run the following on the server (win2003) and a client (win7): icacls c:\path /remove *S-1-5-21-1883347182-1220252494-433279356-1095 /T But I always get the output Successfully processed 0 files; Failed processing 0 files without it doing anything. How can I get it to work? Update: I've used AccessEnum to get the SID because icacls only says "No mapping between account names and security IDs was done." but doesn't show the sid. The output from AccessEnum is: "Path" "Read" "Write" "Deny" "c:\path" "Administrators, S-1-5-21-1883347182-1220252494-433279356-1095, ..."

  • Tracking changes to firewall configs?

    - by jmreicha
    Myself and one other indivdual will be taking over some of the daily firewall management duties soon and I'm looking for a way to track changes on our firewall configurations for auditing purposes and need some ideas on a good way to track changes the changes that are made. I don't have a lot of specific criteria but here are some of the basic things I would like to be able to do: Access to previous revisions of firewall configs Access to changes made and by whom When specific changes were made I'm wondering if some sort of revision control software would work here as a way to track the the changes? Or if some other approach would work better for managing the change control in this situation. I'm open to any and all suggestions at this point. EDIT: We are using a Checkpoint pair, one passive one active configuration. I will update again with specific model numbers when I get a chance.

  • How to configure VirtualBox server for performance at home

    - by BluJai
    I currently have two physical Ubuntu Server 10.10 servers at home: one serves as our firewall/router/DHCP/VPN server and the other performs double-duty as a file server and a VirtualBox host for an Ubuntu Desktop 10.10 machine which I use from remote connections (via NoMachine) for many thin-client purposes which are irrelevant to my question. What I'd like to accomplish is to consolidate the two physical machines into one which is a dedicated VirtualBox host (most likely running Ubuntu Server 10.10). Note that I'd like to stick with VirtualBox (if possible) because I'm most comfortable with it and use it on a daily basis at both home and work. Specifically, I plan to have one VM set up as file server, another as the firewall/router/DHCP/VPN (or possibly split those a bit) and a third, which is the only current VM (already VirtualBox), which is the thin-client host. My question comes down to performance and/or recommendations about the file server VM. The file server hosts about 6 terabytes of data across 4 drives. What I'd like to do is use raw disk access from the VM directly to the existing disks. However, I'm curious what performance advantage/disadvantage that would have as compared to using shared folders from the VM host and basically just have the whole drive served as a shared folder to the VM which would then serve it to the other machines on the network. I don't know if virtual disks would even work in this scenario and I certainly wouldn't want a drive to be filled with just a single file which is 1.5 TB (disk image). To add understanding of context, but not to get additional advice, I want to virtualize these machines because I intend to regularly use the snapshot capabilities of VirtualBox for the system disks (which will be virtual drives) of the VMs and I have some physical space/power needs to address (as I mentioned, this is at home).

  • Configuring Ubuntu for Global SOCKS5 proxy

    - by x50
    Does anyone know the best way to configure Ubuntu to use a SOCKS5 proxy for all network traffic? Server is ubuntu server - all cli. So I cannot set via the Proxy Settings GUI. We want to push all outbound traffic through the proxy (apt-get, http, https, etc). I do need to separate ssh traffic so it stays locally. Everything else should hit the proxy server. not that it matters, but I'm using Squid for the proxy server. I know this is easy on Mac and Windows as you can set a proxy on the actual network interface. Can you do the same on Ubuntu?

  • RHEL 5.1 loses changes to /etc/hosts above lines for `localhost`

    - by warren
    Is there a known fix (other than upgrading from 5.1) to fix /etc/hosts from being replaced on reboot? I discovered this behavior when running HP's Server Automation tools. HPSA sets-up a variety of local aliases for itself to use for different components to communicate wit each other. However, after reboot, the hosts files is reverted to a quasi-plain-vanilla version: all lines above the entry for localhost are removed. Manually re-adding those needed lines below the entries for localhost works, but is non-ideal. Is there a fix for this behavior? I do realize that RHEL 5u1 is not officially supported for HPSA 7.8, but the hosts file resetting is not good for a variety of other reasons, too.
