  • XenServer VMs can't reach network

    - by toto
    I'm currently trying to setup a small cloud architecture , I'm using in the installation CloudStack 2.2.14 which need two node : a management server (as node1) to provision the cloud and a hyperviser XenServer 5.6 SP2 to host the VMs (as node2). I succeded to create both node1 and node2 into an ESXi 5 VMWare as VMs. So The ESXi 5 is hosting two VMs node1 + node2 , and node2 which is the XenServer will host also VMs (such as ubuntu or Centos). Both node1 and node2 can ping each other and can get the internet connection from Esxi5 ,but My problem is : that VMs into the node2(XenServer) can't reach the network (can't ping node1 or Esxi or get an internet connection but they can ping VMs IN the node2(XenServer). So I tried to: 1-Setup a DHCP server as node3 in ESXi5 and connect node2(Xenserver) to him , but always the VMs into to node2 can't reach the outer network. 2-Setup a DCHP server into node2 , but always the same problem. So , 1-is there any other configuration i'm missing in node2 (considering that I'm sure about DNS , GW , NETMASK configuration)?. 2-Is it the problem because i'm Creating VMs into node2(XenSever) which is a VM into ESXi 5 ?

  • Clustered MSDTC

    - by niel
    Hi I'm setting up a SQL cluster (SQL 2008), Windows 2008 R2. I enable the network access on local dtc and then create a DTC resource in my cluster . the problem is that when i start up the resource it does nto pull through my settings to enable network access. the log shows this: MSDTC started with the following settings: Security Configuration (OFF = 0 and ON = 1): Allow Remote Administrator = 0, Network Clients = 0, Trasaction Manager Communication: Allow Inbound Transactions = 0, Allow Outbound Transactions = 0, Transaction Internet Protocol (TIP) = 0, Enable XA Transactions = 0, Enable SNA LU 6.2 Transactions = 1, MSDTC Communications Security = Mutual Authentication Required, Account = NT AUTHORITY\NetworkService, Firewall Exclusion Detected = 0 Transaction Bridge Installed = 0 Filtering Duplicate Events = 1 where when i restart the local dtc service it says this: Security Configuration (OFF = 0 and ON = 1): Allow Remote Administrator = 0, Network Clients = 1, Trasaction Manager Communication: Allow Inbound Transactions = 1, Allow Outbound Transactions = 1, Transaction Internet Protocol (TIP) = 0, Enable XA Transactions = 1, Enable SNA LU 6.2 Transactions = 1, MSDTC Communications Security = No Authentication Required, Account = NT AUTHORITY\NetworkService, Firewall Exclusion Detected = 0 Transaction Bridge Installed = 0 Filtering Duplicate Events = 1 settings on both nodes in teh cluster is the same. I have reinstalled and restarted to many times to mention. Any ideas ?

  • Why can't I connect to my router's config page with Windows 7?

    - by user17940
    I've got a Belkin wireless router, and just bought a new Dell computer with Windows 7 pre-installed. I can connect to the Internet and my home network just fine, but when I try to visit my router's configuration page at http://192.168.2.1, I get a "Connection was reset" error. Nothing I do will make the router's configuration page come up in my web browser. More background information: I could always get to the router's config page from my Windows XP machine. I never had any trouble prior to getting this Windows 7 computer. I can ping 192.168.2.1 successfully from my Windows 7 computer. My PC is connected to the router by a physical CAT5 cable, not via wireless. Every device connected to my router, including the new computer, can get to the Internet with no problem. Here are some things that did not solve the problem: I tried turning off IPV6 in Windows. I tried turning off my firewall and antivirus software I tried using https instead of http I tried disabling and then enabling the network connection in Windows I tried reverting my network card driver back to an older version I have tried both Firefox and Internet Explorer web browsers. Has anyone experienced something like this before, and solved it? Thanks a lot for your help!

  • 503 Error After Microsoft Request Routing Is Installed - 32 bit 64 bit madness

    - by KenB
    I have a requirement to install the Microsoft Request Routing component for IIS 7.5 running on a Windows 2008 R2 SP1 64Bit machine. After installing Microsoft Request Routing via the Web Platform installer our ASP.NET 4.0 application gets a "HTTP Error 503. The service is unavailable." The Windows event log error details says: The Module DLL 'C:\Program Files\IIS\Application Request Routing\requestRouter.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a AMD64 processor architecture. The data field contains the error number. To learn more about this issue, including how to troubleshooting this kind of processor architecture mismatch error, see http://go.microsoft.com/fwlink/?LinkId=29349. I can make this error go away by changing the application pool to run in 32 bit mode by changing the "Enable 32-Bit Applications" setting to true. However I would prefer not to have to do that to resolve the issue. My questions are: Why is the Microsoft Request Routing feature trying to load a 32 bit version, isn't there a 64 bit version for it? How do I resolve this issue without having to change my application pool to a 32 bit mode?

  • how to setup a bridge with 2 NICs and few virtual machines

    - by Bond
    Here is my situation. I have a server with 2 NICs. I have installed virtual box and I have created a few Guest Operating Systems on it. I want these Virtual Machines to be using a bridge.NIC2 would be used to setup this bridge and NIC1 would be connected to corporate network.I am not clear with how should I go on doing this. /etc/network/interfaces is the file which I am trying to modify etc. My approach is following 1) Define a configuration file /etc/network/interfaces 2) Create IPTABLES as how NIC1 will forward the packets to Bridge on NIC2 Now comes the problem I do not understand what is the meaning of following lines in the configuration file auto lo iface lo inet loopback # The primary network interface auto eth2 iface eth2 inet manual auto br0 iface br0 inet static address 192.168.1.14 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.10 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 192.168.13.2 dns-search myserver.net bridge_ports eth2 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off So any pointers to what should be the entries of /etc/network/interfaces file. So that I understand which parameter is to be used when and where that would help me.

  • Apache2 doesn't serve PHP-scripts correctly

    - by cmbrnt
    I've run into a problem with my Apache 2.2.16 configuration, running on Debian Squeeze. The problem is that it stopped serving PHP5-scripts completely. When I try to access the sites with Google Chrome, it instead downloads a file called "download", which contains the contents of the script. This is of course not a good thing. It does serve common html-files perfectly... I've been at this for quite a while now, and after all the googling and troubleshooting, I thought it would be a good time to ask you guys. Here's what I've got: The php5 and libapache2-mod-php5 packages are installed /etc/apache2/mods-available contains both php5.load and php5.conf, and these are symlinked from the mods-enabled directory The /etc/php5/ directory is left untouched since the installation. Here's the contents of /etc/apache2/mods-available/php.load: LoadModule php5_module /usr/lib/apache2/modules/libphp5.so And /etc/apache2/mods-available/php.conf: <IfModule mod_php5.c> <FilesMatch "\.ph(p3?|tml)$"> SetHandler application/x-httpd-php </FilesMatch> <FilesMatch "\.phps$"> SetHandler application/x-httpd-php-source </FilesMatch> <IfModule mod_userdir.c> <Directory /home/*/public_html> php_admin_value engine Off </Directory> </IfModule> </IfModule> What am I missing? This is a server with modified virtual hosts and the like, so I might have changed some settings which causes this problem, but simply purging and reinstalling is not an option so far, since the configuration is quite extensive. Any help would be great. Thanks.

  • How to create an alias for a named SQL Server instance

    - by Svish
    On my developer computer I have an SQL Server instance named *developer_2005*. In the resource setting files of a C# application we are creating, the instance name is set to foobar (not really, but just as an example). So when I run the application (in debug or realease) it tries to connect to an SQL Server on localhost, named foobar. I am wondering if it is possible to create an alias or something like that, so that the application actually finds an SQL Server on localhost named foobar, but it is actually connecting to the instance named *developer_2005*. The connection string in the config file of the application is Data Source=localhost\foobar;Initial Catalog=barfoo;Integrated Security=True with provider name System.Data.SqlClient. If I change localhost\foobar to *localhost\developer_2005* then the application can connect like it should. How can I create an alias so that I won't have to change the string in the file? I tried, in SQL Server Management Studio, to create a Server Registration with registered server name "localhost\developer", but this didn't seem to do any good. Not even sure what that really did... But then I discovered SQL Server Configuration Manager\SQL Native Client COnfiguration\Aliases. And I kind of assume this is where the solution lies. But I can't quite figure out how to add a new one... When creating a new one, I have to provide Alias Name, Port No, Protocol and Server, and I don't really have a clue what to put in either of them.

  • mkfs Operation Takes Very Long on Linux Software Raid 5

    - by Elmar Weber
    I've set-up a Linux software raid level 5 consisting of 4 * 2 TB disks. The disk array was created with a 64k stripe size and no other configuration parameters. After the initial rebuild I tried to create a filesystem and this step takes very long (about half an hour or more). I tried to create an xfs and ext3 filesystem, both took a long time, with mkfs.ext3 I observed the following behaviour, which might be helpful: writing inode tables runs fast until it reaches 1053 (~ 1 second), then it writes about 50, waits for two seconds, then the next 50 are written (according to the console display) when I try to cancel the operation with Control+C it hangs for half a minute before it is really canceled The performance of the disks individually is very good, I've run bonnie++ on each one separately with write / read values of around 95 / 110MB/s. Even when I run bonnie++ on every drive in parallel the values are only reduced by about 10 MB. So I'm excluding hardware / I/O scheduling in general as a problem source. I tried different configuration parameters for stripe_cache_size and readahead size without success, but I don't think they are that relevant for the file system creation operation. The server details: Linux server 2.6.35-27-generic #48-Ubuntu SMP x86_64 GNU/Linux mdadm - v2.6.7.1 Does anyone has a suggestion on how to further debug this?

  • Is there any way to force my Linux box to always boot up with a self-assigned IP address?

    - by Jeremy Friesner
    This is perhaps an unusual request: I'm trying to get a Debian Linux box to always give itself a self-assigned IP address (i.e. 169.254.x.y) on boot. In particular, I want it to do that even when there is a DHCP server present on the LAN. That is, it should not request an IP address from the DHCP server. From what I can see in the "man interfaces" text, there is an option for "manual", and an option for "dhcp". Manual assignment won't do, since I need multiple boxes to work on the same LAN without requiring any manual configuration... and "dhcp" does what I want, but only if there is no DHCP server on the LAN. (A requirement is that the functionality of these boxes should not be affected by the presence or absence of a DHCP server). Is there a trick that I can use to get this behavior? EDIT: By "no manual configuration", I mean that I should be able to take this box (headless) to any LAN anywhere, plug in the Ethernet cable, and have it do its thing. I shouldn't have to ssh to the box and edit files to get it working each time it is moved to a different LAN.

  • Looking for a small, portable, port-mirroring ethernet switch.

    - by user37244
    I recently had a mac go haywire, taking half a minute or more to get www.google.com loaded. Getting its owner to give up the machine for repair was like pulling teeth - they were insisting that it must be something to do with the network, since so much had changed with the local configuration at about the same time their box went haywire. I eventually set up a port mirror to a box that I could remote to so I could show that the mac was only irregularly getting packets onto the network. Demonstrating this faced an additional challenge: the latency of the remote desktop software I was using meant that I had to point to timestamps instead of just the moment the packet flashed up on the screen as my evidence. This particular user was the reason this was so challenging this time around, but I would like to have a box that I can cart from desk to desk to use wireshark on my laptop at any station where I need it. 3com, cisco, netgear, etc. (ad nauseum), all make switches that can be configured for port mirroring, but in my case, the smaller, the better. For the sake of my sanity, I'll probably end up running it off a battery anyway. If my laptop had two ethernet ports, this would be easy. So, whaddya recommand for a device that requires 0 configuration at each powerup (though I'm fine with poking at it for a while to set it up initially.) Small, light, and cheap enough to get it past purchasing? Thanks,

  • IP6 seems to be enabled - How do I configure it without interfering with IP4?

    - by Mister IT Guru
    I noticed that some of my Centos boxes have IP6 enabled, and seem to have addresses. I have no problem with this, but I would like to get a handle on it, and even connect to them using IP6. This would really help if for any reason DHCP has a hiccup. But I'm a bit lost as to where the configuration on my CentOS box is. (I am also on google researching this, but I like server fault! :) ) I am hoping that I would be able to log into this via the VPN because every now and then that DHCP device has a bad morning, and needs to be restarted. (I'm also looking into this issue, but someone else handles that, management separation gone mad!) It's a remote client, so it would be a lot easier for me to connect to these systems which seem to self configure, to use that as a pivot via ssh tunnels to get to other remote devices to continue to manage them, while out main route is fixed. I guess, my questions are How can I configure IP6 without interfering with IP4, and On CentOS, can I influence this auto configuration I seem to be seeing?

  • configuring lighttpd for large downloads

    - by ahmedre
    i run a web site that hosts pages that are just general scripts (php, etc) and mp3 downloads (some of which are fairly large - up to 200mb). i am running lighttpd on the servers on linux (ubuntu 64). everything is fine, but under high load, the server is not accessible (or very slow - even sshing in takes a while), and i am guessing this is due to a huge number of mp3 downloads at that time. consequently, dns sees the server as down and redirects all the traffic to the other servers, and after a while, it comes back up and things work again. so what's the best way to fix this? ideally, i want the server to continue running (and the web pages - php etc - to always work, but downloads don't always have to work). should i just have 2 web servers running (one for the downloads and one for the php pages), or is it perhaps something i can fix in my lighttpd configuration? here are the snippets from my configuration: server.max-worker = 4 server.max-fds = 2048 server.max-keep-alive-requests = 4 server.max-keep-alive-idle = 4 server.stat-cache-engine = "fam" fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 1, "idle-timeout" => 20, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "64", "PHP_FCGI_MAX_REQUESTS" => "1000" ), "bin-copy-environment" => ( "PATH", "SHELL", "USER" ), "broken-scriptfilename" => "enable" )) ) # normal php site $HTTP["host"] =~ "bar.com" { server.document-root = "/usr/local/www/sites/bar.com/" accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/bar.log" } # download site $HTTP["host"] =~ "(download|stream).foo.com" { server.document-root = "/home/audio/" dir-listing.activate = "enable" dir-listing.hide-dotfiles = "enable" evasive.max-conns-per-ip = 1 evasive.silent = "enable" # connection.kbytes-per-second = 256 accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/download.log" }

  • Trouble with nginx and serving from multiple directories under the same domain

  • TLS_REQCERT and PHP with LDAPS

    - by John
    Problem: Secure LDAP queries via command-line and PHP to an AD domain controller with a self-signed certificate. Background: I am working on a project where I need to enable LDAP look-ups from a PHP web application to a MS AD domain controller that is using a self-signed certificate. This self-signed certificate is also using a domain name that is not a FQDN - think of something like people.campus as the domain name. The web application would take the user's credentials and pass them on to the AD domain controller to verify if the credntials are a match or not. This seems simple, but I am having problems trying to get PHP and the self-signed certificate to work. Some people have suggested that I changed the TLS_REQCERT variable from "request" to "never" within the OpenLDAP configuration. I am concerned that this might have larger implications such as a man-in-the-middle attack and I am not comfortable changing this setting to never. I have also read some places online where one can take a certificate and place it as a trusted source within the openldap configuration file. I am curious if that is something that I could do for the situation that I have? Can I, from the command line, obtain the self-signed certificate that the AD domain controller is using, save it to a file, and then have openldap use that file for the trust that it needs so that I do not need to adjust the variable from request to never? I do not have access to the AD domain controller and as a result cannot export the certificate. If there is a way to obtain the certificate from the command line, what commands do I need to use? Is there an alternate method of handling this issue that would be better in the long run? I have some CentOS servers and some Ubuntu servers that I am working with to try and get this going on. Thanks in advance for your help and ideas.

  • setting up tracd behind mod_proxy?

    - by FilmJ
    I'm having trouble setting up mod_proxy and tracd. Seems almost all the search results for this problem take me to the built-in trac documentation page that mentions it as an option. I have several VirtualServers already running on the box in question, so running tracd on port 80 or 443 is not an option, but I do want to make my trac server accessible on this machine without exposing an additional port via the firewall. Making things even more complicated is that I have multiple trac repositories being served by the same instance of tracd, and so I want to set it up so: http://trac.abc.com is proxy'd to localhost:8000/projects/abcproject, and http://trac.def.com is proxy'd to localhost:8000/projects/defproject. Currently, the setup I have below results in 100% 403 errors. The server is running as www-data and the directory where all trac files are stored is owned by www-data, AND tracd (as show below) is running as www-data, so not sure where it's getting hung up. The relevant configuration on /var/apache2/sites-enabled/trac.abc.com: ProxyPass / http://localhost:8000/abcproject ProxyPassReverse / http://localhost:8000/abcproject The relevant configuration on /var/apache2/sites-enabled/trac.def.com: ProxyPass / http://localhost:8000/defproject ProxyPassReverse / http://localhost:8000/defproject The command used to instantiate tracd: tracd -a defproject,/var/www/vhosts/trac-common/users.htdigest,DEFProject -a abcproject,/var/www/vhosts/trac-common/users.htdigest,ABCProject -p 8000 -b localhost -e /var/www/vhosts/trac-common/projects If I access the site at http://localhost:8000/ everything works fine, but if I try to access via any of the proxy'd hosts I end up with 403 at every turn. I've used mod_proxy successfully as described above for other servers, such as couchdb, so maybe this has to do with the headers sent by tracd??

  • Server configration for our website [duplicate]

    - by Varun Varunesh
    This question already has an answer here: Can you help me with my capacity planning? 2 answers We are a start-up and 6 month back we have launched our beta version website. Now we are in a phase of building our website and web-services for the final product. This website will be based on PHP, Python, MySql database and with wamp server. Right now in the beta version we are using Azure VM for hosting, with configuration of 786MB RAM and Shared CPU. We have 200 avg users daily coming to our website. Now we are trying to increase the number of users from 200 to 1500 daily users. And I am thinking our server should have capability to handle at least 100 concurrent user. Also we have developed web-services for our mobile-apps. Which can also increase loads on the sever. So here are the question that takes me here, I am pretty much confused about whether to go with shared hosting or VM based hosting. If VM, then what configuration will be best for our requirement (as I discussed above) ? Currently our VM is a Windows based server and its very simple to manage, So other than cost factor why should I go for Linux based sever? What other factor should I keep in mind while choosing the server as per our requirement ?

  • Wireless router setup for 1-1 NAT

    - by Carlos
    What I have: A linksys router WAG160N with firmware version 2 A "pool" of 5 external static IP's provided by my ISP 213.xx.xxx.n All the required configuration values for the static IPs such as (Subnet Mask, Gateway and static DNS 1, 2, 3) Current WAN Configuration: Encapsulation: RFC 2364 PPPoA Multiplexing: VC QoS type: UBR DSL modulation: MultiMode What's connected to the network: 1 x Server (That I want to make available to the outside) 5 x Desktops with static internal IP's, such as 192.168.0.xx 2 x Network printers, also with internal static IP's 2 x Laptops 1 x NAS (Network Attached Storage) also on static IP What I want to do: I would like to make the server available from outside the network, for example from your house. The problem is that Im not really sure how to do this. I have tried following the steps on the instruction manual in Linksys but they do not seem to work, once I set it up as shown bellow, I loose internet and all hell breaks loose. Going into further detail, I would prefer if the network is changed as little as possible, by this I mean that all the computers stay networked within eachother and only the server is accessible from the outside the network. What I need HELP with: I have read around that it is possible to set a 1-1 NAT (I know where it is in the menu but have no clue what it does...) so that I can NAT a single public IP directly to a single private IP (in our case the server). But please, How do I do that? Or maybe an alternative?

  • In Icinga (Nagios), how do I configure hosts with multiple IPs?

    - by gertvdijk
    I'm setting up Icinga (Nagios fork) and I have some machines with multiple interfaces. Some services are only listening on one of them and to check them correctly, I like to know if it's possible to have multiple IP addresses configured for a single host in Icinga. Here's a minimal example: Remote Server: eth0: 1.2.3.4 (public IP) eth1: 10.1.2.3 (private IP, secure tunnel) Apache listening on 1.2.3.4:80. (public only) OpenSSH listening on 10.1.2.3:22. (internal network only) Postfix SMTP listening on 0.0.0.0:25 (all interfaces) Icinga Server: eth0: 10.2.3.4 (private IP, internet access) Now if I define a host: define host { use generic-host host_name server1 alias server1.gertvandijk.net address 10.1.2.3 } This will not check the HTTP status correctly. And defining an additional host: define host { use generic-host host_name server1-public alias server1.gertvandijk.net address 1.2.3.4 } will check everything, but shows up as two independent hosts. Now I want to 'aggregate' these two hosts to show up as a single host, yet providing an easy configuration to check the services on their proper address. What is the most elegant number-of-configuration-lines-saving solution to this? I read about several plugins available to workaround this, but I can't figure out what is the current way to address it. Solutions go back to 2003, but I'm running Icinga 1.7.1, already capable of the address6 option, yet that triggers IPv6-only resolving on the hostname... Ideally, I wish to configure Icinga to be intelligent enough to know that the Postfix instance running on 10.1.2.3:25 is the same as 1.2.3.4:25 and thus not triggering two alarms. I guess this must have been tackled before and sysadmins have it set up now. Please share your solution to this. Thanks! :)

  • Problems Installing slapd On Ubuntu Server 11.10

    - by Zach Dziura
    I know that there's a Ubuntu-specific StackExchange website, but I thought that I'd ask here because it's a server-specific question. If I'm wrong in my logic... Well, you people are better at this than I am! O=) On with the show! I'm in the process of installing Oracle Database 11g R2 Standard Edition onto Ubuntu Server 11.10. I found a guide on the Oracle Support Forums that walks you through the process fairly easily. Unfortunately, I'm running into issues installing one particular dependency: slapd. When I go to install it, I get this error message: (Reading database ... 64726 files and directories currently installed.) Unpacking slapd (from .../slapd_2.4.25-1.1ubuntu4.1_amd64.deb) ... Processing triggers for man-db ... Processing triggers for ufw ... Processing triggers for ureadahead ... Setting up slapd (2.4.25-1.1ubuntu4.1) ... Usage: slappasswd [options] -c format crypt(3) salt format -g generate random password -h hash password scheme -n omit trailing newline -s secret new password -u generate RFC2307 values (default) -v increase verbosity -T file read file for new password Creating initial configuration... Loading the initial configuration from the ldif file () failed with the following error while running slapadd: str2entry: invalid value for attributeType olcRootPW #0 (syntax 1.3.6.1.4.1.1466.115.121.1.15) slapadd: could not parse entry (line=1051) dpkg: error processing slapd (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: slapd E: Sub-process /usr/bin/dpkg returned an error code (1) After much Google searches and forum trolling, I have yet to find a definitive answer as to what's going wrong. The error messages seem straight forward enough, but I have no idea how to debug this. Can anyone offer some assistance? Again, if I'm asking in the wrong place, I apologize. If I'm indeed asking properly, then thank you for any and all help!

  • RTNETLINK answers: File exists... maybe because assigned a new mac adress

    - by steven
    I got a "RTNETLINK answers: File exists Failed to bring up eth0:1" on "ifup eth0:1". I suspect it happens because i assigned a new mac adress in my VM's network adapter. Can you tell me how to fix the issue? My configuration looks like this: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet static address 192.168.1.80 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 192.168.1.1 # Alias being connected to 192.168.10.x Network auto eth0:1 allow-hotplug eth0:1 iface eth0:1 inet static address 192.168.10.83 netmask 255.255.255.0 gateway 192.168.10.10 dns-nameservers 192.168.10.1 Why do I get "RTNETLINK answer: File exists.." suddenly? I worked with this configuration before without problems. All i did in the past is to renew the adapters mac adress. At the moment I am connected to the 192.168.10.x Network and if I do /etc/init.d/networking stop /etc/init.d/networking start then i got "RTNETLINK [...] falied to bring up eth0:1" but the strage thing is that i am able to connect to 192.168.10.83 via ssh from my host machine. But I cannot reach the internet from the debian client. I hope it is clear what my problem is, now. update if i change my /etc/network/interfaces like this then "ifup eth0" fails, too with the same error! # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet static address 192.168.10.83 netmask 255.255.255.0 gateway 192.168.10.10 dns-nameservers 192.168.10.1 with verbose option enabled i got: Configuring interfache eth0=eth0 (inet) run-parts --verbose /etc/network/if-pre-up.d ip addr add 192.168.10.83/255.255.255.0 broadcast 192.168.10.255 dev eth0 label eth0 RTNETLINK answers: File exists Failed to bring up eth0. same if i type this manually: ip addr add 192.168.10.83/255.255.255.0 broadcast 192.168.10.255 dev eth0 label eth0

  • IIS 7, FastCGI, PHP and custom php.ini files

    - by Marlon
    I'm running PHP 5.3, FastCGI, and IIS 7 on Windows Server 2008. I have a site which I would like to configure its own php.ini settings for but things aren't working as expected. I am following the tutorial located here. This is what I have done so far: 1) Configured a new website with it's own AppPool. 2) Selected PHP 5.3.6 from the PHP Manager available on the website home on IIS (not the web server home which sets the global version of PHP) 3) Added the following lines to the section of the applicationHost.config file located at system32/inetsrv/config <application fullPath="C:\Program Files (x86)\PHP\v5.3\php-cgi.exe" arguments="-d open_basedir=C:\inetpub\wwwroot\kickasswebsite.com" maxInstances="4" idleTimeout="300" activityTimeout="30" requestTimeout="90" instanceMaxRequests="200" protocol="NamedPipe" queueLength="1000" flushNamedPipe="false" rapidFailsPerMinute="10"> <environmentVariables> <environmentVariable name="PHPRC" value="c:\inetpub\wwwroot\kickasswebsite.com" /> </environmentVariables> </application> 4) I then create a php.ini file located in C:\inetpub\wwwroot\kickasswebsite.com (the location of the root of the website) register_globals = on 5) I then run test.php which simply outputs everything the method call to phpinfo() returns. At this point, I observe that the global setting for register_globals = off (as it should be), but the local setting for register_globals = off, even though I specified it differently in the php.ini file I created at the root of the site. Furthermore, I see these settings in the output of the php.ini Configuration File (php.ini) Path C:\Windows Loaded Configuration File C:\Program Files (x86)\PHP\v5.3\php.ini Scan this dir for additional .ini files (none) Additional .ini files parsed (none) What am I messing up on, or is there a different way to go about this?

  • Apache httpd: Send error logs to syslog and local disk? Without touching /etc/syslog.conf?

    - by Stefan Lasiewski
    I have an Apache httpd 2.2 server. I want to log all messages using syslog, so that the requests are sent to our central syslog server. I also want to ensure that all log messages are sent to local disk, so that a sysadmin can have easy access to the log files on the local system. It is easy to send HTTP access logs to both the local disk and to syslog. One common method is: LogFormat "%V %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined CustomLog logs/access_log combined CustomLog "|/usr/bin/logger -t httpd -i -p local4.info" combined But it is not easy to do this for error logs. The following configuration doesn't work, because the error logs only use the last ErrorLog stanza. The first ErrorLog stanza is ignored. ErrorLog logs/error_log ErrorLog syslog:local4.error How can I ensure that Apache errors logs are written to the local disk and are sent to syslog? Is it possible to do this without touching /etc/syslog.conf ? I am fine if my users want to manage their own Apache configuration files, but I do not want them touching system files such as /etc/syslog.conf

  • Apache Redirect is redirecting all HTTP instead of just one subdomain

    - by David Kaczynski
    All HTTP requests, such as http://example.com, are getting redirected to https://redmine.example.com, but I only want http://redmine.example.com to be redirected. For example, requests for I have the following in my 000-default configuration: <VirtualHost *:80> ServerName redmine.example.com DocumentRoot /usr/share/redmine/public Redirect permanent / https://redmine.example.com </VirtualHost> <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> . . . </VirtualHost> Here is my default-ssl configuration: <VirtualHost *:443> ServerName redmine.example.com DocumentRoot /usr/share/redmine/public SSLEngine on SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key BrowserMatch "MSIE [2-6]" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown <Directory /usr/share/redmine/public> Options FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> LogLevel info ErrorLog /var/log/apache2/redmine-error.log CustomLog /var/log/apache2/redmine-access.log combined </VirtualHost> <VirtualHost *:443> ServerAdmin webmaster@localhost DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> . . . </VirtualHost> Is there anything here that is cause all HTTP requests to be redirected to https://redmine.example.com?

  • How do I configure VMware View location-based printing to use Active Directory Groups?

    - by Jason Pearce
    I am attempting to configure VMware View 4.5's Location-Based Printing, which leverages an included OEM version of ThinPrint, to assign printers to active directory groups. The location-based printing feature maps printers that are physically near client systems to VMware View desktops. I am using the Active Directory group policy setting AutoConnect Location-based Printing for VMware View, which is located in the Microsoft Group Policy Object Editor in the Software Settings folder under Computer Configuration. The AutoConnect Location-based Printing for VMware View appearst to be just a name translation table. It permits me to assign a specific printer or printers to an IP Range, Client Name, Mac Address, User, or User Group. I'm attempting to assign printers to active directory user groups. I have created a new active directory group for each printer that I intend to use in VMware View desktop pools. I will then assign active directory users to the active directory groups that represent each network printer. Example: doej is a member of the PTR-FLOOR2-NORTH-ROOM255 active directory group. Using AutoConnect, I assigned the group to receive a network printer by adding PTR-FLOOR2-NORTH-ROOM255 in the User/Group column. Problem: When doej logs in to his VDI session, the printer is not present. However, if I use a wildcard "*" in the User/Group column instead of the specific PTR-FLOOR2-NORTH-ROOM255 active directory group, the printer is present and functions as designed. Alternatives: I have tried assigning printers to active directory groups within AutoConnect in the following ways, all unsuccesfull: PTR-FLOOR2-NORTH-ROOM255 domainexample\PTR-FLOOR2-NORTH-ROOM255 domainexample.local\PTR-FLOOR2-NORTH-ROOM255 Confirmation: The information used to map the printer to the VMware View desktop is stored in a registry entry on the View desktop in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\thinprint\tpautoconnect. For each of these examples, I have reviewed the registry entry and can confirm that the desktop is receiving the information from the AutoConnect translation table. Summary: Can anyone provide an example of how to configure VMware View 4.5's Location-Based Printing so that I may assign network printers to active directory groups via the included AutoConnect tool? I would welcome a clear example of a working configuration. Thank you.
