  • Moodle serves on IP only - will not work with mod_proxy

    - by Jon H
    I'm trying to set a moodle server up on an Ubuntu box, which already serves Plone & Trac via Apache. In my Moodle config I have $CFG-wwwroot = 'http://www.server-name.org/moodle' The configuration below works fine for the first two, but when I visit www.server-name.com/moodle I get: Incorrect access detected, this server may be accessed only through "http://xxx.xxx.xxx.xxx:8888/moodle" address, sorry It then forwards to the IP address, where Moodle functions fine. What am I missing to get the server name approach working correctly? Apache Config follows: LoadModule transform_module /usr/lib/apache2/modules/mod_transform.so Listen 8080 Listen 8888 Include /etc/phpmyadmin/apache.conf <VirtualHost xxx.xxx.xxx.xxx:8080> <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPreserveHost On <Location /> ProxyPass http://127.0.0.1:8082/ ProxyPassReverse http://127.0.0.1:8082/ </Location> </VirtualHost> <VirtualHost xxx.xxx.xxx.xxx:80> ServerName www.server-name.org ServerAlias server-name.org ProxyRequests Off FilterDeclare MyStyle RESOURCE FilterProvider MyStyle XSLT resp=Content-Type $text/html TransformOptions +ApacheFS +HTML TransformCache /theme.xsl /home/web/webapps/plone/theme.xsl TransformSet /theme.xsl FilterChain MyStyle ProxyPass /issue-tracker !

  • Cisco Multi-DMZ firewall

    - by BParker
    I need to find a firewall that will give me 1 LAN port, and 5-7 DMZ ports. I have a requirement to replace some FreeBSD systems that are used to run some testing equipment. It is essential that the DMZ ports cannot communicate with each other, but the LAN port can communicate with everyone. That way a user on the LAN can connect to the test systems, but the test systems are isolated entirely and cannot interfere with each other. One of the DMZ's will be connected to a VMWare ESXi server, one to a standard server, and the rest to various types of equipment. The lan port will be connected to the corporate LAN switch. Sorry if i am a little vague, I am just trying to work all this out myself! Currently we have a FreeBSD configured, but the quad port NIC's are pretty expensive, and the PC itself is old, so i would prefer to replace it with a dedicate piece of kit which can do the same job, but more reliably! These test rigs are used all over the place, and get moved quite often, so i am aiming for Cisco kit for ease of configuration and reliability of the hardware itself. Thanks

  • Raid-5 Performance per spindle scaling

    - by Bill N.
    So I am stuck in a corner, I have a storage project that is limited to 24 spindles, and requires heavy random Write (the corresponding read side is purely sequential). Needs every bit of space on my Drives, ~13TB total in a n-1 raid-5, and has to go fast, over 2GB/s sort of fast. The obvious answer is to use a Stripe/Concat (Raid-0/1), or better yet a raid-10 in place of the raid-5, but that is disallowed for reasons beyond my control. So I am here asking for help in getting a sub optimal configuration to be as good as it can be. The array built on direct attached SAS-2 10K rpm drives, backed by a ARECA 18xx series controller with 4GB of cache. 64k array stripes and an 4K stripe aligned XFS File system, with 24 Allocation groups (to avoid some of the penalty for being raid 5). The heart of my question is this: In the same setup with 6 spindles/AG's I see a near disk limited performance on the write, ~100MB/s per spindle, at 12 spindles I see that drop to ~80MB/s and at 24 ~60MB/s. I would expect that with a distributed parity and matched AG's, the performance should scale with the # of spindles, or be worse at small spindle counts, but this array is doing the opposite. What am I missing ? Should Raid-5 performance scale with # of spindles ? Many thanks for your answers and any ideas, input, or guidance. --Bill Edit: Improving RAID performance The other relevant thread I was able to find, discusses some of the same issues in the answers, though it still leaves me with out an answer on the performance scaling.

  • How-To Configure Weblogic, Agile PLM and an F5 LTM

    - by Brian Dunbar
    Agile, Weblogic, and an F5 walk into a bar ... I've got this Agile PLM v 9.3 Running on WebLogic, two managed servers. An F5 BigIP LTM. We're upgrading from Agile v 9.2.1.4 running on OAS. The problem is that while the Windows client works fine the Java client does not. My setup is identical to one outlined in F5's doc: http://www.f5.com/pdf/deployment-guides/bea-bigip45-dg.pdf When I launch the java client it returns this error "Server is not valid or is unavailable." Oracle claims Agile PLM is setup correctly, but won't comment on the specifics of the load balancer. F5 reports the configuration is correct but can't comment on the specifics of the application. I am merely the guy in a vortex of finger-pointing who wants my application to work. It's that or give up on WLS and move back to OAS. Which has it's own problems but at least we know how it works. Any ideas?

  • How can I enable PHP5 for a site? Having problems with every single method.

    - by John Stephens
    I'm working on a client site that is hosted on someone's DIY Debian Linux server [Apache/1.3.33 (Debian GNU/Linux)], and I'm trying to install a script that requires PHP5. By default, the server parses .php files with PHP 4.3.10-22, which is configured at /etc/php4/apache/php.ini, according to phpinfo(). On the server I can see a config directory for PHP5 adjacent to the PHP4 directory: /etc/php5.0/apache2/php.ini. I have tried multiple methods to enable PHP5 for the document root where the site's files are hosted, including all available methods mentioned here. By far, the most common suggestion I've found is to add one or both of the following lines to the site's .htaccess file: AddHandler application/x-httpd-php5 .php AddType application/x-httpd-php5 .php Trouble is, when either or both of those lines are present, the site forces my browser to download any .php files requested, without parsing the PHP at all. All of the other methods mentioned in the above article cause a 500 Internal Server Error. There is no hosting control panel I can access in a browser to enable PHP5 for the site, but I do have shell access. When I asked the server administrator about this issue, he encouraged me to search for the answer on Google. Where could I begin to troubleshoot this issue? Are there ways to test or verify the server's specific PHP5 installation and configuration, using the command line or some other method? Do you have other suggestions to enable PHP5?

  • How can I have puppet deploy ssh keys for virtual users?

    I am trying to get puppet to assign authorized ssh keys for virtual users but I keep getting the following error: err: Could not retrieve catalog: Could not parse for environment production: Syntax error at 'user'; expected '}' at /etc/puppet/modules/users/manifests/ssh_authorized_keys.pp:9 I believe my configuration are correct (listed below) but is there a syntax error or scoping issue I am missing?

  • squid will not listen on specific IP

    - by Chris
    I have a public subnet with squid installed. Let's say my subnet is from 1.2.3.2 to 1.2.4.254. When I set the following: http_port 50000 http_port 1.2.3.2:50000 it is working. But when I set: http_port 1.2.4.37:50000 it is not working. It is only working with my first public IP from my subnet. The error I get when it is not working is the following: commBind: Cannot bind socket FD 10 to 1.2.4.37:50000: (99) Cannot assign requested address What is wrong with my configuration? @Zoredache I have a dedicated server and the whole subnet is defined as IP Range. When I use only the port or the first IP and doing netstat -ntlp | grep 46555 I get the following: tcp 0 0 0.0.0.0:50000 0.0.0.0:* LISTEN 25532/(squid ) When I use my specific IP, then the netstat query will show nothing, as the server does not start. I don't want squid to listen on all or the first IP, it is just a specific one it should listen to.

  • Is the sysadmin/netadmin the defacto project planner at your organization?

    - by gft74
    At my company it has somehow over the past few years slowly become my job to come up with a project plan, milestones and time lines for deployment of developer applications. Typical scenario: My team receives a request for a new website/db combo and date for deployment. I send back a questionnaire for the developer to fill out on all the reqs for the site (ssl? db? growth projections etc.) After I get back all the information, the head of development wants a well developed document of what servers will it live on why those servers what is the time line for creating the resources step-by-step SOP for getting the application on the server and all related resources created (dns, firewall, load balancer etc.) I maybe just whining but it feels like this is something better suited to our Project Management staff (which we have) or to the developer. I understand that I need to give them a time-line on creating the resources, but still feel like this is overkill. We already produce documentation on where everything lives and track configuration changes to equipment. How do other sysadmin folks handle this?

  • How to Change the Kerberos Default Ticket Lifetime

    - by user40497
    Our KDC servers are running either Ubuntu Dapper (2.6.15-28) or Hardy (2.6.24-19). The Kerberos software is the MIT implementation of Kerberos 5. By default, a Kerberos ticket lasts for 10 hours. However, we'd like to increase it a bit (e.g. 14 hours) to suit our needs better. I had done the following but the ticket lifetime still stays at 10 hours: 1) On all the KDC servers, set the following parameter under [realms] in /etc/krb5kdc/kdc.conf and restarted the KDC daemon: max_life = 14h 0m 0s 2) Via "kadmin", changed the "maxlife" for a test principal via "modprinc -maxlife 14hours ". "getprinc " shows that the maximum ticket life is indeed 14 hours: Maximum ticket life: 0 days 14:00:00 3) On a Kerberos client machine, set the following parameters under [libdefaults], [realms], [domain_realm], and [login] in /etc/krb5.conf (everywhere basically since nothing I tried had worked): ticket_lifetime = 13hrs default_lifetime = 13hrs With the above settings, I suppose that the ticket lifetime would be capped at 13 hours. When I do "k5start -l 14h -t ", I see that the end time for the "renew until" line is now 14 hours from the starting time: Valid starting Expires Service principal 04/13/10 16:42:05 04/14/10 02:42:05 krbtgt/@ renew until 04/14/10 06:42:03 "-l 13h" would make the end time in the "renew until" line 13 hours after the starting time. However, the ticket still expires in 10 hours (04/13 16:42:05 - 014/14 02:42:05). Am I not changing the right configuration file(s)/parameter(s), not specifying the right option when obtaining a Kerberos ticket, or something else? Any feedback is greatly appreciated! Thank you!

  • Passenger throwing undefined method `-@' for "master":String after Puppet 3.0.0 upgrade

  • Creating a ssh tunnel to transfer files?

    - by Vincent
    For me, networks are a very "opaque" thing, and even with reading a lot of tutorial about SSH, I do not understand how to create a basic tunnel to transfer my files. The configuration is the following : My Computer --[Internet]--> Bridge Machine --[Local Network]--> Final Machine Currently I do the following : 1) Connect to the Bridge Machine with : ssh -X [email protected] 2) Connect to the Final Machine with : ssh -X username@finalmachine 3) I copy the address of files I need (for example .../mydirectory) 4) Then I deconnect from the finalmachine with : exit 5) I copy the files to the bridge : scp -r username@finalmachine:/.../mydirectory . 6) I deconnect from the bridge with : exit 7) I copy the files to my machine : scp -r [email protected]:/.../mydirectory . Which is quite complicated. My question is basic : how to simplify this using a SSH tunnel ? (and please explain me the signification of each command line you write, to understand what each line really do and to avoid to use it like a magical thing. Furthermore if some ports number are used, explain me if I can pick a completely random number or if I have to choose a specific one.)

  • Importing csv list of contacts into Exchange 2007 GAL and create Distribution Group

    - by Ken Ray
    Here's the situation: We have a list of about 1,000 contacts (Lawyers in the area our court serves) with name and email address. I've been asked to create an email distribution list that can be used to sent emails to all of the external users on that list. I've seen various articles using the Exchange Management Shell and the Import-csv command piped through a ForEach-Object to a New-MailContact to set up the contacts. However, Exchange Management Shell is rather unhelpful, and it isn't working. What I believe I need to do is: 1) Set up a new distribution group using the Exchange Management Console. Let's say this new distribution group (which appears in the list of Distribution Groups under Recipient Configuration) is called "FloridaBar". 2) Make sure I have a csv file of the information I want to import. 3) Open Exchange Management Shell, and enter the following command: Import-csv C:\filename.csv | ForEach-Object { New-MailContact -Name $."NameColumnName" -ExternalEmailAddress $."EmailAddressColumn" -org FloridaBar Now, creating 1,000+ contacts in active directory - I assume that shouldn't be an issue. Do I have the "-org" parm wrong? Do I need to spell out the complete organization unit name (my.domain.name/Users/FloridaBar)? Is there a better way of doing this? Thanks in advance Ken

  • "Windows cannot find" file when opening Excel spreadsheet

    - by DanH
    For all of my Excel spreadsheets when I attempt to open them (by double-clicking in explorer) I get the message "Windows cannot find C:...". The files are there, and are valid zip files as seen by 7-Zip. There are no apparent lock files in the directories. I did just install Norton-360 over the weekend (replacing Kasperski), but the Norton log shows no events related to Excel. However, while installing Norton I did reboot with some Excel files open. Presumably something is hosed in my Excel configuration but I don't know what. Update (Before actually posting) -- I found an article that suggested turning off Advanced Option "Ignore other applications that use DDE", then doing excel.exe /unregister followed by excel.exe /register. I tried this but I suspect that the two Excel calls were ignored (Excel opened, but no obvious change). With that option off the spreadsheets load OK, but not with it on. And, curiously, spreadsheets load OK with the option on or off if I open Excel first and then open the spreadsheet in it. Does anyone have any idea what effect leaving that option off will have? Update 2 -- I tried running the "repair" option. It said it corrected a couple of config things (without saying what they were), but I still get a failure if I double-click an Excel file with the "Ignore other applications..." option checked. Update 3 -- I managed to fix this problem, but failed at the time to come back and say what I did, and now I can't remember for sure. But I think it had something to do with "Options"/"Save" and some of the values there. Something to do with AutoRecover, perhaps. (Possibly there was a file in recovery and I had to specify "Disable AutoRecover for this workbook" to let bring-up get past it. Or perhaps the AutoRecover file location was hosed.) Anyway, if it happens to someone else, and you find the fix, post it below and I'll mark it answered.

  • Remote desktop connection to network printer

    - by andand
    I'm trying to print a document from a remote WinXP machine to a network printer I use on a local Win7 machine using Remote Desktop. The network printer does not appear in the list of those available on the WinXP box. In more detail, the local machine runs Windows 7 (no admin rights) and connects to a network printer managed by a print server (i.e. not using a local TCP/IP Port). I have access to a Windows XP host on a separate network which I access using Remote Desktop. I would like to have print requests from the remote XP box forwarded to the network printer I use on the Windows 7 machine. The XP machine cannot access the print server I use on the Win7 machine nor can it create a TCP/IP port to connect directly to the printer (network configuration issues). After having consulting the KB312135 I confirmed the "Printers" option was selected in the Remote Desktop Client, Local Resources Tab, yet the network printer does not appear on the list of available printers on the XP box. Is this a lost cause or is there something else I haven't managed to locate yet?

  • Apache logging issues

    - by Dan
    I'm trying to parse apache log files, but I'm finding some strange results and I'm not sure what they mean. Hopefully someone can provide some insight. (all of the IP addresses were altered. none actually start with 192, I didn't figure the search engines mattered though.)

  • Virtual Lan on the Cloud -- Help Confirm my understanding?

    - by marfarma
    [Note: Tried to post this over at ServerFault, but I don't have enough 'points' for more than one link. Powers that be, move this question over there.] Please give this a quick read and let me know if I'm missing something before I start trying to make this work. I'm not a systems admin professional, and I'd hate to end up banging my head into the wall if I can avoid it. Goals: Create a 'road-warrior' capable star shaped virtual LAN for consultants who spend the majority of their time on client sites, and who's firm has no physical network or servers. Enable CIFS access to a cloud-server based installation of Alfresco Allow Eventual implementation of some form of single-sign-on ( OpenLDAP server ) access to Alfresco and other server applications implemented in the future Given: All Servers will live in the public internet cloud (Rackspace Cloud Servers) OpenVPN Server will be a Linux disto, probably Ubuntu 9.x, installed on same server as Alfresco (at least to start) Staff will access server applications and resources from client sites, hotels, trains, planes, coffee shops or their homes over various ISP, using their company laptops or personal home desktops. Based on my Research thus far, to accomplish this, I'll need: OpenVPN with Bridging Enabled to create a star shaped "virtual" LAN http://openvpn.net/index.php/open-source/documentation/miscellaneous/76-ethernet-bridging.html A Road Warrior Network Configuration, as described in this Shorewall article (lower down the page) http://www.shorewall.net/OPENVPN.html Configure bridge addressesing (probably DHCP) http://openvpn.net/index.php/open-source/faq.html#bridge-addressing Configure CIFS / Samba to accept VPN IP address http://serverfault.com/questions/137933/howto-access-samba-share-over-vpn-tunnel Set up Client software, with keys configured for access (potentially through a OpenVPN-Sa client portal) http://www.openvpn.net/index.php/access-server/download-openvpn-as/221-installation-overview.html

  • Ubuntu xrandr rotate issue

    - by user83544
    I've just bought a second monitor for my PC which happens to be a pivot monitor. I've already read lots of forums related to my problem but haven't come across a solution - I have the same symptoms as dozens of posts but no matter whatever I try it just doesn't work. I've already changed the xorg.conf file and added in the device section just under Driver "nvidia" the following for my second monitor: Option "RandRRotation" "on" When I save and reboot I try to rotate my screen with the nvidia X server settings by choosing the second monitor and clicking either "left" or "right" for the rotation. It immediately exits the nvidia settings window and does nothing. I tried within the terminal by typing: xrandr -o right I get the following error: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 154 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 I actually manage to rotate it with Option "Rotate" "CCW" instead of "RandRRotation". The problem with this solution is that you get the second monitor in the right position, but any window you open on that screen is practically unchangeable. You can't change the size nor move it, making it useless for reading PDFs, which is the main reason why I bought this second screen to help me write my thesis. Any help is really appreciated. sudo lshw -c video hiram@hiram-linux:~$ sudo lshw -c video *-display description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:f8000000-f9ffffff memory:d8000000-dfffffff memory:d4000000-d7ffffff ioport:dc00(size=12 memory:fbd80000-fbdfffff

  • OSX Server 10.5 - Cannot log into Workgroup Manager - diradmin password is correct

    - by Mister IT Guru
    I've got a setup where I am trying to rescue a broken AD. We can no longer authenticate on the Workgroup manager, with passwords being rejected all the time - even though it is correct. I can connect using the workgroup manager on another server and I get the user list as expected, but when I click the padlock to make changes, I get the following screen: The problem is, I know the password is correct, I just used it to connect to the server in the first place. I can log into the server using the local admin, and services such as AFP, VPN and SMB continue to serve users. I have about 300 or so users on this server, and I would very much like to avoid having a rebuild. As there is much configuration that has been done without my knowledge (it's a client machine), I'd like to attempt to fix it, and then create another server and migration OD off this broken machine, then decommission it "gently". Ultimately this would mean no disruption of services. What I'd like it some tips as to how to fix the problem with authenticating to make changes in the work group manager, and maintenance on open directory in general. Thanks

  • Is basing storage requirements based on IOPS sufficient?

    - by Boden
    The current system in question is running SBS 2003, and is going to be migrated on new hardware to SBS 2008. Currently I'm seeing on average 200-300 disk transfers per second total across all the arrays in the system. The array seeing the bulk of activity is a 6 disk 7200RPM RAID 6 and it struggles to keep up during high traffic times (idle time often only 10-20%; response times peaking 20-50+ ms). Based on some rough calculations this makes sense (avg ~245 IOPS on this array at 70/30 read to write ratio). I'm considering using a much simpler disk configuration using a single RAID 10 array of 10K disks. Using the same parameters for my calculations above, I'm getting 583 average random IOPS / sec. Granted SBS 2008 is not the same beast as 2003, but I'd like to make the assumption that it'll be similar in terms of disk performance, if not better (Exchange 2007 is easier on the disk and there's no ISA server). Am I correct in believing that the proposed system will be sufficient in terms of performance, or am I missing something? I've read so much about recommended disk configurations for various products like Exchange, and they often mention things like dedicating spindles to logs, etc. I understand the reasoning behind this, but if I've got more than enough random I/O overhead, does it really matter? I've always at the very least had separate spindles for the OS, but I could really reduce cost and complexity if I just had a single, good performing array. So as not to make you guys do my job for me, the generic version of this question is: if I have a projected IOPS figure for a new system, is it sufficient to use this value alone to spec the storage, ignoring "best practice" configurations? (given similar technology, not going from DAS to SAN or anything)

  • NFS headaches with FreeBSD 4.9

    - by Ernie
    Once upon a time, this used to work, and I kept the configuration the same, but... now nothing. I'm just trying to get an NFS server set up on a FreeBSD 4.9 server. The process should be about as complicated as this: Add this entry to /etc/exports: /var/home /var/vpopmail/domains -maproot=root XXX.XX.XX.XXX Execute this: portmap nfsd -u -t -n 4 mountd -r Then this should work, regardless of network and firewall issues: showmount -e localhost But showmount -e localhost fails with the following error: RPC: Port mapper failure showmount: can't do exports rpc And even if I kill off the NFS daemon, and try a rpcinfo -p localhost, I get this error: rpcinfo: can't contact portmapper: rpcinfo: RPC: Unable to receive; errno = Connection reset by peer The portmapper is still running. Why the heck does nothing work as if it isn't? Edit to add: FYI: Sockstat gives me this: $ sockstat |egrep "(nfsd|portmap)" root nfsd 86310 3 udp4 *:2049 *:* root nfsd 86310 4 udp4 *:973 *:* root portmap 45920 0 tcp4 *:111 *:* Then, at a later time (say, 5 minutes) it's as if nfsd isn't acting as a server: $ sockstat |egrep "(nfsd|portmap)" root portmap 45920 0 tcp4 *:111 *:* But the nfs daemon is still running: $ ps ax |grep nfsd 86311 ?? I 0:00.00 nfsd: server (nfsd) 86312 ?? I 0:00.00 nfsd: server (nfsd) 86313 ?? I 0:00.00 nfsd: server (nfsd) 86314 ?? I 0:00.00 nfsd: server (nfsd)
