  • Remote installation and configuration software, preferrably open source

    - by Brimstedt
    Hello, Im looking for some remote-installation software. I've looked briefly at unattended, opsi and a bunch of stuff, but there is nowhere near enough time to evaluate them all, and they are rather complex to setup so some insight would be very appreciated. This is foremost for windows clients, but linux support would be good. Something like apt-get would've been great. Requirements: Simple to setup and use Set up groups of users (developers, management, sales, etc) Chose which software to be installed for different groups Add new software to groups and it will be automatically installed on client Dependencies between software Nice-to-have: Linux client support OS-unattended installation thanks in advance

  • Use all 5.1 speakers with a 2.1 audio source

    - by thegreyspot
    Hi! I just bought a 5.1 surround sound speaker set for my computer in my bedroom. The rear speakers are next to me in bed while the front speakers are at the other end of the bed at my feet. While I enjoy the surround sound during movies that support 5.1 sound, I would like to have my rear speakers working when listening to podcasts, or other 2.1 channel sound. How can I do this? When I enable "Speaker Fill" in the Realtek Hd Audio manager the sound only comes out of the front and center speakers with a few background noises that come out the rear ones. But since my ears are closer to the rear speakers, I'd rather have the sound come out of them. Let me know of any ideas! Hmm seems like the only option is to set the rear speakers to "Front Speakers" and change it to stereo in the Realtek HD audio. But still that take alot of steps and it doesnt not use the center speaker Thanks

  • Good source of reviews of CULV machines?

    - by Jason Sundram
    I'm potentially interested in acquiring a CULV machine. I like the idea of a netbook, but need a little more horsepower. So, of course, I need to obsess over a hundred different reviews first. Can you recommend some good sources of CULV reviews? Anandtech recently ran a roundup, but I'd prefer sites that have ongoing CULV coverage. Thanks!

  • hiera data source in using puppet syntax?

    - by Zoredache
    The documentation for hiera on docs.puppetlabs.com seems to give me the impression that I can use puppet syntax to describe my data. Or posssibly will be able to in the future. See: Coming soon. Is this functionality present in a release version of puppet, and just not documented, or is this still being developed? If this functionality is present, does anyone have examples of how to actually use this? The presence of the puppet_backend.rb file on my system gives which was part of the puppetmaster package makes me thing that this functionality is present, but just not documented. So I am trying to figure out how to actually use this.

  • 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 set JS source directory in apache2?

    - by highBandWidth
    I am trying to run a very basic webserver for development/debugging. The static HTML seems to be delivered correctly, but it seems that the JavaScript libraries are not being delivered to the browser. The page HTML says something like <html> <head> <script type='text/javascript' src="/lib/json.js"></script> ... Now, I have set up a link for /lib/ in my httpd.conf as: Scriptalias /lib/ "/SomeFolder/lib/" When I do this, it can't fetch the files because this is what I see in my apache error log: ... [error] [client ::1] client denied by server configuration: /SomeFolder/lib/json.js, referer: http://localhost/SomeSite It seems that apache is not allowing access to the folder, so I add this to httpd.conf: Directory "/SomeFolder/lib/"> Allow from all </Directory> After this, browsing the page still does not run the JS, instead I see the following error in my apache error log: [error] [client ::1] (13)Permission denied: exec of '/SomeFolder/lib/json.js' failed, referer: http://localhost/SomeSite So now, it seems that apache is trying to run the JS files on the server like a cgi script or something. But I have not made that folder a cgi-bin folder. The only lines where SomeFolder is mentioned by name is in these lines in httpd.conf: Scriptalias /lib/ "/SomeFolder/lib/" Directory "/SomeFolder/lib/"> Allow from all </Directory>

  • Open source calendar software allowing sync with Iphone?

    - by Jared
    I'm looking for something I can install on a Linux server to create a remote calendar that I can sync with my iphone. Anything requiring setting up an exchange server on the Iphone is out since I already have one set up for work. I'd like to avoid a groupware package since all I really want is a calendar.

  • IP telephony open source systems

    - by danke
    I'm trying to pick an IP telephony technology to learn. I heard of Asterisk, trixbox, freePBX, and my head was already spinning being not sure what to learn. Then I came across this article listing some more like Kamailio, Yate, CallWeaver, FreeSWITCH, SipXecs and now my head REALLY is spinning http://www.cio.com.au/article/323016/five_open_source_ip_telephony_projects_watch . Can someone give me a run down of how all these technologies tie together? What is the trend now, because I'd like to start learning. Note: Anyone please re-tag this question if you know better, because I'm new to this field and not sure about the best tags.

  • Finding source of leaking active memory on Mac OS Lion

    - by Tim Kemp
    My activity monitor shows 6GB of active RAM usage: Yet my Real Memory column shows nothing like that amount: (There's another screenful below that, all smaller.) Backing that up, the output from this command (which sums up memory usage of every running process): ps -axm -o "rss,comm" | awk 'BEGIN { s=0;}; {s=s+$1;}; END { printf("%.2f GB\n", (s/1024.0/1024));}' Gives 4.09GB, so it looks to me like 2GB has leaked. I see much wider ranges sometimes, perhaps 2 or 3GB from the ps command and as much as 7 or 8GB of Active usage reported by Activity Monitor. I've tried quitting everything and logging my user out and back in again, but the Active usage is still far higher than the RAM reported by ps and by each process to Activity Monitor. This 2GB of active RAM is basically unrecoverable unless I reboot. Is there any way to a) detect what's leaking and b) get it back? Thanks

  • Using LDAP Attributes to improve performance for large directories

    - by Vineet Bhatia
    We have a LDAP directory with more than 50,000 users in it. LDAP Vendor suggests maximum limit of 40,000 users per LDAP group. We have number of inactive users and those are being purged but what if we don't get below the 40,000 users? Would switching to using multivalued attribute at user record level instead of using LDAP groups yield better performance during authentication, adding new users, etc? I know most server software (portal, application servers, etc) use LDAP groups. But, we have a standardized web service interface for access control instead of relying on server software to map LDAP groups to security roles. Each application uses this common "access control web service". Security roles are used within application to build fine-grained ACL used within each enterprise application.

  • how to install mpgtx from source code

    - by Ahmet vardar
    i am new on linux server. i have mpgtx folder in my root, how can i install it ? in readme file it is written; ./configure && make when i type this i get permission denied error ? thanks EDIT: Here the steps i done root@server [/]# cd /mpgtx root@server [/mpgtx]# ./configure -bash: ./configure: Permission denied root@server [/mpgtx]# make ----------------------------------------------------------------------------- Hello ! I'm afraid I'm a dummy Makefile. My goal in life is to politely ask you to run the configure script to actual- ly generate a real Makefile. Would you be kind enough to type "./configure --help" to see the options that will suit your needs ? Please note that typing "./configure" without option will generate a Makefile that will suit most people needs. I wish you a good day. Please don't drive to fast. ----------------------------------------------------------------------------- root@server [/mpgtx]# ./configure -bash: ./configure: Permission denied root@server [/mpgtx]#

  • Website deployment - managing uploaded content?

    - by Legion
    I'm a programmer by trade, "server administrator" by company necessity. We're looking at dumping the old painful "update site by FTP upload" style of deployment. Having the webserver check out the latest code base from version control into a folder and having a "current" symlink point to the latest checkout (allowing for easily stepping back to an older version by changing the symlink) seems to be the way we want to go. But I have a question: what's a good practice for dealing with user-uploaded content? This stuff isn't in version control. I have a couple of ideas for dealing with this, but what is the smart, accepted practice?

  • How to know the source of certain TCP traffic on AIX

    - by A.Rashad
    We have two AIX boxes, one for production system and another for testing. both systems are running ATM machine switches, where the ATM device is connected via TCP socket. we had an issue on production system where the machine would power off or get disconnected but the netstat -na | grep <IP of machine > would still mention that the socket is up when simulated that case on the UAT environment, the problem did not happen, where the socket would terminate in 3 to 5 minutes. when sniffed on the traffic between the machine and ATM we found that no traffic takes place on production while there is some sort of heartbeat on UAT. but it is not initiated by the application. $>tcpdump | grep -v "10.2.2.71" | grep -v "HSRP" | grep "10.3.1.30" tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on en6, link-type 1, capture size 96 bytes 09:08:13.323421 IP server073.afs3-callback > 10.3.1.30.impera: . 278204201:278204202(1) ack 3307884029 win 164 09:08:13.335334 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:08:23.425771 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:08:23.425789 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 09:09:13.628985 IP server073.afs3-callback > 10.3.1.30.impera: . 0:1(1) ack 1 win 164 09:09:13.633900 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:09:23.373634 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:09:23.373647 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 while on production, that traffic is not there. we want to know where this traffic is initiated from to implement on production to sense disconnection our comms parameters are: tcp_keepcnt = 2 tcp_keepidle = 100 tcp_keepinit = 150 tcp_keepintvl = 150 tcp_finwait2 = 1200 can anyone help?

  • Tracking down source of duplicate email messages in Outlook / Exchange environment

    - by Ken Pespisa
    I have a few users, who are also Blackberry users, that occasionally have duplicate emails generated from their "mailbox". I put mailbox in quotes because I'm not exactly sure where the duplicates are created. One of these users is in non-cached mode, and the other is in cached mode, and both experience the problem. In fact, the non-cached mode user was originally experiencing the problem while in cached mode, and I made the switch a few weeks ago to attempt to solve the problem. Today I discovered the issue still exists. I'm not sure if the fact that they are blackberry users could be causing the problem at all. I don't see how, but felt I should mention it anyway. Does anyone have ideas on how I might begin to troubleshoot this? I can see in the non-cached user's mailbox "Sent Items" that the message was sent only once. I confirmed the message does not state that there was a conflict and in fact that makes sense because they are in non-cached mode. On the server, we have a mail journaling feature turned on for our third-party mail archiving system, and I can see that that system sees two sent messages. And likewise, the recipient does in fact have two messages in their inbox with consecutive message IDs ([email protected]) and ([email protected]). It would seem to me that the duplicates are generated on the client, but is there a way to tell for sure?

  • Stream audio source from Mac OS X as MP3

    - by Adam Backstrom
    I'd like to broadcast audio from my Mac desktop to my Palm Pre, as the Pre is more portable and I can use it in the kitchen, or while I'm exercising, and so on. I can already capture the audio using Soundflower, but how might I create an MP3 stream out of the audio input device? For all intents and purposes, Soundflower can reduce this question down to, "How can I create an MP3 stream from the built-in microphone on my Mac?" as the answer can be applied equally well to iTunes output.

  • Are there any open source reseller packages?

    - by Tom Wright
    My department has just been given the right/responsibility to manage our own VPS. The idea being that the bureaucracy will be less for the many small web projects we run. Since each project will be managed by a different team, I was planning on approaching a shared hosting model. Are there any free pieces of software that would help automate the provision of resources each time a team request a new project? Most of the projects have identical requirements - basically LAMP - so it would be these resources that I would want provisioning (and de-provisioning, if that is a word) automatically. Ideally, there would also be a way to hook it into our LDAP authentication backend too, though I could probably make this sort of modification if necessary. Since we won't be charging our "client" however, we won't need the ability to generate invoices, handle payments, etc. etc. EDIT: Sample workflow Login authenticated against LDAP Username checked against admin group (not on central LDAP) Click 'new project' and enter project name User created on VPS with project name as username Apache virtual host created and subdomain (using project name) allocated FTP & MySQL users created

  • How can I restrict SSH access when the source IP is dynamic

    - by Supratik
    Hi I want to protect SSH access to our live web server from all IP's except our office static IP. There are some employees who connects to this live server from their dynamic IP's. So, it is not always possible for me to change in the iptables rule in live server whenever the dynamic IP of the employee changes. I tried to put them in office VPN and allowed only SSH access from office IP but the office connection is slow in compared to our employee's private internet connection, moreover it adds an extra overhead to our office network. Is there any way I can solve this problem ?

  • Determining the Source of a Given File System Mount on Unix [migrated]

    - by phobos51594
    Background Recently I have run into a bit of a snag on my home FreeBSD server. I recently upgraded it to the latest stable release, and I have noticed some strange behavior with the /var partition. Originally, I had the system configured such that /var had its own partition with /var/run and /var/log in memory disks (/tmp, too). After the upgrade, I notice there is a new, fourth memory disk mounting directly to /var that I had not set up manually and is not in my fstab. It is only 28 megs or so in size and is causing problems when trying to update my ports collection. The ramdisk mounts atuomagically at boot and cannot be unmounted while in multi-user mode. If I drop to single user mode, I am able to unmount it without issue, however rebooting causes it to pop right back up. System specifications have been included at the end of the post. Question Is there any way to determine exactly what is mounting a given memory disk (or any filesystem, for that matter) after it has been mounted? Alternately, does anybody have any ideas what might have caused the new /var ramdisk to pop up?

  • Control copy/paste doesn't work

    - by Guest
    I have a laptop HP PAVILION dv6-3126er with Windows 7 Home Edition installed and neither control copy nor control paste doesn't work (i've tried: ctrl+c, ctrl+v, shift+c, shift+v, ctrl + insert, shift + insert). I've tried to run a system check through cmd with sfc /scannow, it repaired something, i restarted but it didn't solve the problem. I've also tried many key combinations (like alt+ctrl+fn), but nothing works in any program. In Microsoft Word 2003 in the menu i have no key combination for copy/paste near them (in my previous comp they've been there - in brackets). Shift+Delete works by the way. I brought this laptop a few weeks ago, and i discovered this problem in the first days. I have no viruses because i have had no time to even connect him to internet. Anyways, i checked it for viruses - it is clean. I don't want to do system restore, because i see no reason to do it for a pretty clean system. I hope it is not a problem with the laptop itself. Maybe there is another reason? Maybe i need to do some more system checks? Any suggestions? Thanks in advance.

  • Using AutoHotKey to change audio output source?

    - by Scott
    I have two primary audio outputs on my machine: The speakers and a USB headset. Currently, in Windows 7 Professional x64, I type "sound" in the Start search menu to open up this dialog: I only care about the top two options for the purposes of this question. I would like to know if there's a way in AutoHotKey to switch from "Speakers (4- Sennheiser USB Headset)" to "Speakers (VIA High Definition Audio)" so I can avoid having to open this dialog every time I wish to switch. Thanks!
