• Netboot Intel Macs without BSDP

  - by notpeter

  I have a netboot setup with DeployStudio that works great in my lab, but doesn't work on our main network. After some digging, I believe it's because our network admins are filtering BSDP (Boot Service Discovery Protocol) on our subnet at the switch level. Is it possible to hard code which server my clients (early 2007 iMac Core2Duos) should boot from without relying on BSDP? Perhaps relevant details: I do not have control over switch configs or DHCP settings. Client and server are running 10.6 Snow Leopard. The clients see the netboot server advertising itself in the 'Startup Disk' system preferences pane, but when I go to netboot it just leaves me with a flashing globe.

• pix 501, static route to d-link router (different subnet)

  - by ra170

  I have pix 501 cisco firewall with internal ip 192.168.10.1. I have connected d-link router (dir-655) to pix 501. The d-link router has internal ip 192.168.0.1 The picture would like something like that: |pix 501| has 192.168.10.1 ip |DIR-655| has 192.168.0.1 ip 1. |cable modem|----|pix 501|-------|DIR-655|-----PC 2. PC--------|pix 501|---------|DIR-655| | | |cable modem| When I'm on the wireless network (dir-655) with assigned ip of 192.168.0.x I can cross the subnet and connect to my firewall 192.168.10.1. (pic. 1) The problem is that if I'm on the 192.168.10.x network I can't connect to anything over at 192.168.0.x network. (pic.2) I've tried entering a static route like this: `route inside 192.168.0.0 255.255.255.0 192.168.10.1 1` I also tried assigning static ip to wan interface on DIR-655 to 192.168.10.30 and then tried this: route inside 192.168.0.0 255.255.255.0 192.168.10.30 1 But still, can't connect to 192.168.0.1 or anything on that subnet. Is there a way to setup a static route? Would adding a separate router between PIX 501 and DIR-655 help? I would think that static route like this should take care of it, but it doesn't. This is my route config and nat: (config)# sh route outside 0.0.0.0 0.0.0.0 (outside_IP) 1 DHCP static outside (outside_IP) 255.255.248.0 (outside_IP) 1 CONNECT static inside 192.168.0.0 255.255.255.0 192.168.10.1 1 OTHER static inside 192.168.10.0 255.255.255.0 192.168.10.1 1 CONNECT static or (route inside 192.168.0.0 255.255.255.0 192.168.10.30 1) (config)# sh nat nat (inside) 1 192.168.1.0 255.255.255.0 0 0 nat (inside) 1 192.168.10.0 255.255.255.0 0 0 nat (inside) 1 0.0.0.0 0.0.0.0 0 0 I ended up turning DIR-655 into an Access Point (turning off DHCP and pluging cable from PIX lan interface into one of the LAN interfaces on DIR-655, and leaving WAN port empty), that works as far as DIR-655 being on the same subnet now, and I can access every machine. However the question is, why can't I simply route between those two? would router between these two help? One of the reasons is, that the PIX 501 has only 10 licences, so now I'm using almost all of them. (I have few computers, iphones, ps3, print server, etc.) I would really appreciate some help! Thanks.

• Windows 7 Locks Up or Blue Screens after installing additional hard drive

  - by Ryan

  I've had my home theater pc for over a year now and it's been running with no problems what so ever. I got myself a new Seagate 2 TB hard drive for the holidays and ever since installing it the pc now randomly locks up or blue screens either upon putting it to sleep or waking it from sleep. The only thing I've tried so far is updating the firmware on the hard drive. The hard drive in question is this one (http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4846365). I do have my minidump file saved off on my home theater pc however right now I'm at work and don't have access to it. Please help! Thank you!

• What does a red icon in XP's "Unlock Computer" dialog mean?

  - by wikiti

  A user was working from home and had a colleague turn on her computer so she could remote desktop to it. All worked fine, but when she came into the office and used her computer for a while then locked it the computer icon had a red screen, instead of blue. Like in the following mockup: Mockup of red computer screen. It didn't cause any problems and it went away when she rebooted, but I was intrigued to find out whether there was something that caused it or if it was just a windows oddity. I believe she just closed the remote desktop session (without really logging off) from home and then disconnected from the VPN before coming to the office. Any ideas?

• Removing perl module installed with cpanm

  - by ZeC

  I am Perl beginner. I wanted to use Log::Log4perl module as I am familiar how it works in Java. I used cpanm script to download module, but I ran it without "sudo". Then it installed this module to my dir /home/amer/perl5. Afterwards, I installed it as sudoer, but I want to remove installation in my home dir to avoid any conflicts in future. How can I do that? Here is my cmdline execution stack. Thanks and Regards!

• How do I change the document root of a Linux Apache server?

  - by Daryl Spitzer

  I'm trying to learn how to configure an Apache HTTP server (with which I have no experience) someone else has setup in a VM running Ubuntu 8.04. I know the server is running, since I get "<html><body><h1>It works!</h1></body></html>" when I go to http://1.2.3.4/ (where 1.2.3.4 is the VM's IP number). I found apache2.conf and httpd.conf (among other files) in /etc/apache2/. httpd.conf is empty. I tried adding DocumentRoot "/home/username/temp" into /etc/apache2/httpd.conf and put some simple HTML in /home/username/temp/index.html. But when I reload http://1.2.3.4/ there's no change. Do I need to restart httpd to get it to accept the change to DocumentRoot?

• Oracle Secure Global Desktop - Business Continuity During Snowstorm!

  - by Mohan Prabhala

  Capgemini, one of the world's largest management consulting, outsourcing and professional services companies, is an Oracle Secure Global Desktop customer and uses it to provide secure, remote access to 1) corporate applications centralized in the datacenter and 2) desktops hosted on Oracle VDI. Earlier this month, one of Capgemini's government customers in Holland were advised to avoid traveling to work, due to a heavy snowstorm. This resulted in a lot of employees working from home. Thankfully due to their deployment of the Oracle Secure Global Desktop gateway, employees were able to easily access their corporate applications and desktops from home and anywhere outside of their office. Capgemini reports that during the days of the snowstorm, a record number of users leveraged Oracle Secure Global Desktop (servers and gateway). Despite this record usage, Oracle Secure Global Desktop remained perfectly stable and allowed users to seamlessly access their applications and desktops. This is a great example of how Oracle Secure Global Desktop allows employee productivity and business continuity even during severe weather conditions such as snowstorms. We are delighted to have enabled business continuity for Capgemini's customers, and look forward to our continued relationship with Capgemini. This blog has been approved for posting by Capgemini.

• Juniper SRX1400 VPN

  - by ank

  I have been trying to set up a client VPN on a Juniper SRX1400 without much success. All documentation I found from Juniper and elsewhere does a lot of other (difficult and wonderful) things other than the simple things I want to do. We already have a VPN running on CISCO PIX hardware which we need to put to rest and we pretty much like to replicate the functionality, which is: 1) client makes a request to the outside interface of the SRX1400, 2) client gets authenticated, 3) if successful, then client is assigned all the usual DHCP stuff and becomes part of the network. What privileges this DHCP assigned network has, should be configurable of course with the usual routing/filtering methods. Am I asking for too much from the SRX for this kind of thing? Should I ditch the SRX for VPN and revert to an OpenVPN solution that I had working some time back also and was amazed at the ease of configuration, functionality and features?

• Problem with Xen, xvda and sda

  - by Javier J. Salmeron Garcia

  I am creating a cloud for my university using Eucalyptus with Xen (PCs have Debian Squeeze 64 bit installed). I have a problem with the following guest configuration: # # Configuration file for the Xen instance evenmorefinalfoo, created # by xen-tools 4.2 on Thu May 26 11:03:06 2011. # # # Kernel + memory size # kernel = '/boot/vmlinuz-2.6.32-5-xen-amd64' ramdisk = '/boot/initrd.img-2.6.32-5-xen-amd64' vcpus = '1' memory = '128' # # Disk device(s). # root = '/dev/sda2 ro' disk = [ 'file:/home/xen/domains/evenmorefinalfoo/disk.img,sda2,w', 'file:/home/xen/domains/evenmorefinalfoo/swap.img,sda1,w', ] As you can see, the disk and swap images are meant to be mounted on sda1 and sda2. However, when I start the guest, these are mounted on xvda1 xvda2, provoking an error. Is there anything that I can do about that? It seems like it is a Xen error. Thank you in advance,

• Backup Linux Root Partition (Fedora 12)

  - by SomeNewbie

  I setup my partition scheme to have an extra partition the size of my / partion. I have a separate home directory partition. Essentially, I will be doing things that might make my OS unstable so I'd like to backup the OS state but without bothering my home directory. Can I just backup (maybe with dd?) my root partition to another partition on the HDD? I know to restore it I would have to boot up with a livecd or something and do the reverse procedure. I want this to be as simple and require the least amount of external hardware as possible.

• File access with hostname or ip only - no domain?

  - by Jonathon

  It seems likely that this is an obvious question, but I'm having trouble tracking down any useful information. Normally when accessing files in a particular directory on a server, I'm able to create a virtual host, assign a domain, root directory location, etc -- however am in a situation where I have server space and need to access files with only a hostname. Is this possible? For example, let's say the hostname is 123hostname.com, and the file I want access to is in /home/sub-directory/filename.php. How do I get at it via a browser? I've tried: http://123hostname.com/home/sub-directory/filename.php ...and some other variations on that theme (that I can't post because new users are restricted to one link in messages). But generally stuck. Any help -- even if it's just to let me know that this isn't possible without some additional configuration -- would be great. Thank you!

• After closing the ssh terminal, the thin server is down

  - by Keating Wang

  I have a rails project run on the thin server(1.3.1) on a ubuntu server. I ssh to the server and start thin with command 'thin start -C config/thin.yml', following the thin.yml, port: 3000 log: log/thin.log timeout: 30 chdir: /home/byht/56platform/dev/tracker environment: production servers: 1 daemonize: true After thin starts successfully, I visit the project and it works well. Then, I close the terminal, I can also visit the pages that have been visited, but when I visit the pages that not been visited before closing ssh terminal, a "500" error appears on the page. I didn't find the error messages in the log file. I have tried start thin with nohup and sudo, but they are useless. I sign in the ubuntu server locally, then the problem disappears. But I need sign in the server to stat thin with ssh when I'm home.

• Get source and destination of outbound traffic in pfSense

  - by maxsilver

  I'm looking at the traffic graph in pfSense (Version 1.2.2), which we're using as a router / NAT / ect on our network. Recently, I'm seeing a sudden, constant spike of 15 - 30kbps traffic outbound, that is unusual for our network (normally its below 2kbps, we're mostly all inbound traffic) Is there any way to determine what the source of this traffic is, or where it's going? (Just an internal IP address for source, and external IP address for destination would be all I need) I've already tried switching the traffic graph to 'LAN' and watching the host list on the right side, but it seems ... flakey. The numbers it shows seem to fade in and out at random, and the values never add up to anywhere near the graph values. I'm not allowed to post the image, but a photo is available at - http://imgur.com/QYjKI.png

• keepalived questions (requirements, abilities, limitations)

  - by Poni

  1) What are keepalived's (physical/network) requirements? Does the two (or more) keepalived' nodes need to be connected to the same switch? (something related to broadcasting maybe). 2) Can keepalived nodes run on different networks, "internet" networks? 3) Is keepalived depend on the router? (as far as I understand, the virtual IP should point to the real router/switch that connects both nodes). 4) Is keepalived "service-independent"? - What is keepalived's involvement domain? IPs only? Or is it service/protocol oriented? - Does it deal ONLY with IP, or is it designed for HTTP for example? - In other words, can I use it for custom (network-based) app? 5) Have more than one failover server? If the answer for question #4 is "yes", i.e it depends on the service type, then is there any general alternative? Preferably easy to install/configure :)

• How to set up Windows server 2008 to receive email?

  - by Saul

  First off apologies, I'm from a medical background not a networking one, but I've got roped into setting up a windows 2008 server. So far web server running, fixed IP address assigned (within a large private network of the National Health Service in the UK if that makes any difference) and the network team have assigned a DNS entry for me which works, so the server can be addressed as nww.myserver.nhs.uk I've only got ports open on the router for 80 and 443 (http and https) at the moment, so presume I need a different port to enable email services. My need is to be able to accept an email to the domain name like [email protected] in order to pick up a confirmation mail from an SSL issuer (Comodo) I guess to confirm that I control the domain. After that I don't actually need mail services on the server. I see lots of stuff about setting up SMTP services but thought that was about mail out and re-routing, but how do you get the server to "listen" for mail to the domain (assuming I open port xyz or whatever it is) ?

• Using AdSense to show ads to logged-in users

  - by John

  I know that you can grant authorization permissions to Google AdSense so that it can 'log in' and see what other logged in users can see (e.g. in a private forum), so that the ads it displays are better targetted. Extending this principle further: I am making a site which will show completely different content for each individual user (i.e. not 'common' content like a forum in which everybody sees essentially the same thing). You could think of this content as similar to the way each Facebook user has a different news feed, but it is the 'same' page. Complicating things further, the URLs for this site will be simple, e.g. '/home' and '/somepage', and will not usually include unique identifiers to differentiate between users (e.g. '/home?user=32i42'). My questions are: Is creating an account purely for AdSense to log in to the site with worth it in this case, seeing as it will be seeing it's own 'personalized' version and not any other user's? More importantly: is that against the Google AdSense Terms of Service? (I can't seem to figure that one out) How would you go about this problem?

• Subversion multi checkout post-commit hook?

  - by FLX

  The title must sound strange but I'm trying to achieve the following: SVN repo location: /home/flx/svn/flxdev SVN repo "flxdev" structure: + Project1 ++ files + Project2 + Project3 + Project4 I'm trying to set up a post-commit hook that automatically checks out on the other end when I do a commit. The post-commit doc explicitly lists the following: # POST-COMMIT HOOK # # The post-commit hook is invoked after a commit. Subversion runs # this hook by invoking a program (script, executable, binary, etc.) # named 'post-commit' (for which this file is a template) with the # following ordered arguments: # # [1] REPOS-PATH (the path to this repository) # [2] REV (the number of the revision just committed) So I made the following command to test: REPOS="$1" REV="$2" echo "Updated project $REPOS to $REV" However when I edit files in Project1 for example, this outputs "Updated project /home/flx/svn/flxdev to 1016" I'd like this to be: "Updated project Project1 to 1016" Having this variable allows me to specify to do different actions per project post-commit. How can I specify the project parameter? Thanks! Dennis

• How to configure Dovecot to not serve large emails to high-latency clients?

  - by Daniel Quinn

  I have a Dovecot mailserver running at home on a flaky cable connection. For the most part, the IMAP functionality works beautifully, but I'd like to add one feature if I can: I want Dovecot not to serve large messages to high-latency clients. That is to say, if someone decides that it's a good idea to send me a 9.3mb email to me, I don't want to get it unless I'm on my LAN at home. This can't be an uncommon request, but I'm having trouble finding the configuration option in their documentation. Any ideas and/or good keywords to use in Googling would be awesome.

• Multicast in private LAN with different subnets

  - by Gobliins

  after i read Multicast IP Addresses and Multicast accross the subnets I am confused. Configuration: I have two devices in the same network. They may not be in the same Subnet, but always in the same physical network (beyond the same router, switch etc.) I want to communicate across IP multicast either 224.x.x.x or 239.x.x.x may be more fitting because we want it local, not beyond of forward through the router. Can one machine be the receiver and the other machine sender of the same multicast address? and can the receiving machine send an answer to the sending machine?

• Can I find the session ID for a user logged on to another machine?

  - by Dan Tao

  I want to open an application on another computer on the same network via the command line. The scenario here is that the user is in a room surrounded by about 20 computers and wants to be able to launch the same app on every computer without walking from screen to screen opening it up on each individual machine. I've discovered that I can get the basic functionality for this using PsExec as follows: psexec \\[computer] -u [username] -p [password] -d -i [SessionID] [program] For computer, username, password, and program, I'm good. Does anyone know of a way I can figure out which SessionID is assigned to a particular user logged on to a particular machine on the network? Alternately, is there a better way to go about what I'm trying to accomplish?

• Drupal 7 Advice Needed: "Portal" Creation

  - by WernerCD

  Question: What is the best game plan for building what I want. I'm rebuilding the company intranet and am trying to get our "Portals" system re-created in Drupal. I'm trying to learn Panels, because thats what I think would do this, but I just can't seem to get it working. Menu at top, drop down lists for various webpages, tools, internal applications... and Department Portals. When you click on a department portal, you get the same menu at top... and on the main part of the page you have a menu on the left, with content on the right. Menu stays on the left, content loads next to it. Each Portal has its own menu and content (least of which is "Home"). Ultimately, I'd like to be able to say - users with role "Foo" can add/edit/delete Portal Bar. - Each Portal starts with a "Home" - Each Portal has its own Menu tree's. (Picture 2 above has a < ul for video tutorials that would be a second level menu. So more than one deep.) - Content on the right side of the portal should be flexible (Video, PDF via fileviewer, etc) - Portal Bar should have its own Folder to contain it's content. I'm trying to do this in Panels, but I can't seem to put the pieces together in my mind and in practice. I hope I'm making sense, because the dizzying array of stuff is killing me lol.

• Java.net Reborn

  - by Bob Rhubart

  Java.net, the home of  Java community projects, has been re-launched with a new look and new tools for developers.  The move from CollabNet to the Kenai infrastructure offers more flexibility for developers who want to host or contribute to community projects.  Instead of the large, fixed infrastructure per project (for example, several mailing lists per project), Kenai's ala carte features allow users to take only what they need. "We will continue to have the great mix of blogs, forums, and editorial content as well as new tools on the project side, including Mercurial, Git, and JIRA for developers," Java.net Community Manager Sonya Barry explains.  The migration was huge effort. Over 1400 projects were migrated (and some 30 projects are left to go). A large part of the migration was a big cleanup of abandoned projects. With the high abandonment rate of open source projects, the was a lot to remove. The new java.net site is smaller, faster and now the percentage of good, current content is much higher.
