• Issues with DHCP over multiple subnets

  - by Dan Monego

  I have a cisco router configured to handle multiple subnets (10.1.10.n, 10.2.10.n, etc), and an ubuntu system serving DHCP to the computers served by the router. After a restart of the DHCP, the systems on the 10.1 subnet are fine, but neither the server or the computers configured on the other subnets can see the router at 10.2.10.1 (or 10.3.10.1, or 10.4.10.1). The router can see itself at 10.2.10.1, however. The change that caused this was restarting the server, so I'm approaching it assuming the configuration error is on that end. Is that the likely issue or is there a different problem that would prevent the machines on the 10.2.10 subnet from resolving DHCP?

• Realtek HD Audio playing weird with certain video formats

  - by dyasny

  Hi, I have a Gigabyte motherboard with an onboard Realtek HD sound card. The card is working perfectly everywhere, except for a single video format, where the voice is distorted, sounds as if it's been passed through a metal tube. Been googling for this, but couldn't find an answer anywhere. The movie plays fine on other systems (got Linux everywhere else), but on this one (winXP-x64-sp2) it just doesn't. Here are some details: MPC: Type: KLCP WMV File Audio: 0x000a 22050Hz mono 20Kbps [Raw Audio 0] Video: Windows Media Video 9 400x300 29.97fps 227Kbps [Raw Video 1] VLC: Codec: wmas Sample rate: 22050 Bits per sample: 16 Bitrate: 20kb/s

• compTIA-AT EXAM

  - by SysPrep2010

  Hello everyone, I have been in the IT field only for two years. I have been dealing with servers, firewalls, routers, switches, backup servers, and desktop. For the desktop, i have been dealing with WDS (Window deployment services). Not a lot of hardware. My question is this, is it really important to have an AT cert under your belt. I dont see the point anymore. When a desktop goes down, what have been seeing, they just buy a new one. I mean I can rebuild systems they are fun, but I haven't in a while?

• Virtualmin Configuration

  - by Allen

  I am trying to get Virtualmin setup and have reached a point where my noobish sysadmin skills aren't getting the job done. This is the message I get now when I try and refresh the configuration of Virtualmin. BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server XXXXXX is not a fully qualified domain name. Sendmail is only accepting SMTP connections on the following ports : 127.0.0.1 port smtp. Email from other systems on the Internet will not be accepted. This can be changed in the Sendmail Mail Server module. Please advise what I need to do to get Sendmail configured properly. Thanks!

• 4 - 7 second delay accessing Mysql across the network

  - by Kristiaan

  Hello, our company has recently purchased a new server with the intention of replacing our aging database server. its a full 64bit 2008 enterprise system, i have got the basic server setup and configured and then installed the 64bit version of mysql on the server, this has then been configured to match where possible our existing server as much as it can. however i have noticed that when it was swapped with the production database server our software systems had an increased delay accessing the mysql database this was anything beween 4 - 7 seconds. i have tried disabling TOE, IPv6 and a few other suggested soultions to this but so far cannot find out where this slowdown is coming from. replacing the server with the production one and the delay goes away. in terms of software and hardware the servers are not very identical at all due to one being windows 2003 std with a 32bit server and the new one being windows 2008 enterprise with a 64bit server. thanks Kris

• SSH tunnel & Rsync thru two proxy/firewalls

  - by cajwine

  Screnario: [internal_server_1]AA------AB[firewall_1]AC----+ 10.2.0.3-^ ^-10.2.0.2 | internet 10.3.0.3-v v-10.3.0.2 | [internal_server_2]BA------BB[firewall_2]BC----+ Ports AC,BC has valid internet addresses. All systems run linux and have root acces to all. Need securely rsync internal_server_1:/some/path into internal_server_2:/another/path My idea is make ssh secure tunnel between two firewalls, e.g. from firewall_1 firewall1# ssh -N -p 22 -c 3des user2@firewall_2.example.com -L xxx/10.3.0.3/xxxx and after will run rsync from internal_server_1 somewhat like: intenal1# rsync -az /some/path [email protected]:/another/path I don't know how to make a correct ssh tunnel for rsync (what ports need tunnel) and to where i will make the rsync? (remote comp address in case of ssh tunnel) Any idea or pointer to helpfull internet resource for this case? thanx.

• Installing Domain Controller on Hyper-V Host

  - by MichaelGG

  Given a resource limited setup consisting of 2 host machines (HyperV-01 and HyperV-02), is it OK to put the domain controllers in parent partition, instead of their own VM? The main reason is that if the DCs go into a child partition, starting from cold on both machines could lead to a bit of an issue, as there'd be no DCs around until well after both parents have booted. I'm guessing this might cause undesirable effects. Am I correct to be worried about joining the host systems to a domain that's only on VMs? The biggest drawback I've heard so far is that if AD gets heavily used, its resources could cut into HyperV's. I'm not concerned about that for this deployment. Any other suggestions? (Besides finding a 3rd machine and running AD on it.)

• Windows Despooler Requires Administrator to Print

  - by Software Monkey

  Does anyone know what changes I might need to make to allow restricted users to print using a printer configured for spooling? My Windows XP SP3 system currently requires me to use an Admin account for printing if the print is configured to spool documents before printing. If the printer is configured for direct printing it works for all accounts. This used to work and some months back it just stopped, and I can't pin down why. The printer itself is configured for all uses to have complete authority. My system is locked down for restricted users given them only read authority to the entire file system except their data directories, which is how I have run my systems for years. I assume there may be a directory somewhere that I need to allow users to write to.

• 32bit Application Memory Usage on 64bit Windows 7

  - by Brian

  I have an early 2012 Macbook Pro with and Intel I7 processor and 16 gigs RAM running Windows 7 Professional 64bit via Bootcamp. I work in Geographical Information Systems as a programmer so most of the applications I am running are 32bit Applications, but tend to use a lot of resources (i.e. ArcGIS, SQL Server Express, Visual Studio, etc.). I have been noticing that when I have multiple instances of either the same 32bit application or different 32bit applications and they are all working on hefty processing tasks, I am still only topping out at about 30% memory use. I understand 32bit applications are limited to less than 4gb RAM, but I assumed that one instance could use its own 4gb while another instance could use another 4gb to take full advantage of all the memory I have installed. Can anyone explain how this works and how I can get my applications to take advantage of all my memory via running multiple instances?

• why is iometer performance slower after first run?

  - by Dan

  I'm doing some benchmarking with IOMeter, and I'm seeing a consistent and susbtantial drop-off in performance after running the first test. These drop-offs are about the same on the three systems I've tested on, which makes me think it's a configuration setting, or just a fact of life about using IOMeter. For example, one system (local RAID 10) went from 388 I/Os per second the first run, to about 211 I/Os per second on every run after that. Everything else about the test was identical, and I also bounced the machine in between runs. So, is this expected behavior, or am I missing something?

• How do i get a more recent version of Java on my Mac than is showing up in software update?

  - by Cd Lolly

  I need at least Java 1.6 to run a program that someone else in my lab wrote On the Java website it tells me to update Java via apple's software update function, i've run this a few times but it only got up to Java 1.5.0_24 and it now says no more updates are available for my computer Is there another way to update Java on a Mac? Is my operating system maybe to old for Java 1.6? i'm not sure what i'm running exactly, and i can't find a list of what mac operating systems run what versions of Java because the java site just suggests using Mac's software update.

• Basic IIS7 permissions question

  - by Tom Gullen

  We have a website, with a file: www.example.com/apis/httpapi.asp This file is used by the site internally to make requests joining two systems on the website together (one is Classic ASP, the other ASP.net). However, we do not want the public to be able to access the file. In IIS7.5, is there a setting I can do to make this file internal only? I've tried rewriting the URL for it but this rewrite is also applied internally so the scripts stop working as they fetch the rewritten url. Thanks for any help!

• Advice on new hardware firewall for a small company server-environment

  - by Mestika

  Hi everyone, My companies currently hardware firewall (an old ZyXEL ZyWALL firewall) and is indeed requiring an update to a new firewall. It is a small company with a similar small server-environment, so the need for a huge, complex and expensive solution isn’t there but a more “straight-forward” firewall, that can provide the necessary security to our systems and block unwanted elements from the core server and only accept access through our one server which is used as an “gateway” between the Internet and our internal network. I haven’t that much experience with hardware firewalls so I’m requesting any good advice and/or knowledge on which products will be suited for our specific need. If you need more information about the specific needs we require, please let me know and I’ll provide them to you. Sincerely - Mestika

• Finding how a hacked server was hacked

  - by sixtyfootersdude

  I was just browsing through the site and found this question: My server's been hacked EMERGENCY. Basically the question says: My server has been hacked. What should I do? The best answer is excellent but it raised some questions in my mind. One of the steps suggested is to: Examine the 'attacked' systems to understand how the attacks succeeded in compromising your security. Make every effort to find out where the attacks "came from", so that you understand what problems you have and need to address to make your system safe in the future. I have done no system admin work so I have no idea how I would start doing this. What would be the first step? I know that you could look in the server log files but as an attacker the first thing that I would do would be errasing the log files. How would you "understand" how the attacks succeeded?

• How to install multiple versions of the same software?

  - by Matt Love

  I manage phone systems for multiple clients. Each system uses the same administrator software, but it runs on different versions depending on what version of firmware is installed on the system controller. The software is downloaded directly from the system controller so it's the right version. For example, if the controller runs on version 5.0.2, you have to run version 5.0.2 of the administrator software. You can't administrate a 5.0.2 controller with a later versions of administrator software. Bottom line, you have to have the right version of software to log into the controller. The software is not executable on its own, you have to install it. So every time I want to log into a different controller, I have to reinstall the right software. Any way to get around this? I'm running Windows 7 Enterprise x86.

• NAT and ISP Subnet when load balancing on pfsense?

  - by dannymcc

  I have a pfsense box that I'm trying to plan the configuration for. I am going to be load balancing two ISP's, each with their own /29 static IP subnet. The question I have is in relation to the way those IP's are associated with workstations on the local network. Currently I have some workstations with local (192.168.1.0/29) IP addresses, and other more complicated workstation setups have their own public IP address. Some of the more complicated systems have a NAT 1:1 configuration where I forward a public IP address to a local IP address. Others however are directly on the ISP subnet and cannot be seen on our local network. Is this configuration possible with pfsense? If so, what terms should I be looking through the documentation for? Here is a simple/brief diagram of what I am trying to achieve.

• Security when, ssh Private keys are lost

  - by Shree Mandadi

  Cant explain my problem enough with words, Let me take an example.. and please multiple the complexity by a 100 for the Solution. User-A has two ssh private keys, and over time has used this public key on a number of servers He lost one of them, and has created a new pair. How does User-A, inform me (Sys Admin), that he has lost his key, and How do I manage all the servers to which he had access to (I do not have a list, of all Servers that User-A has access to). In other words, How do I recall, the public key associated with this Private key. REF: In the LDAP based Authentication, All Servers would communicate with a single Server repository for Authentication, and If I remove acess or modify the password on the Server, all Systems that use this LDAP for Authentication are secured, when User-A loses his password..

• Why do partially failed/failing switches fail to pass DHCP?

  - by David Mackintosh

  I've noticed this several times: a switch starts to behave oddly. Usually if the switch doesn't fail outright, what tends to get noticed is that DHCP doesn't work. We had a Linksys SRW-224P fail today. Systems which were still connected worked properly, until it came time to renew their DHCP lease. Once the lease expired, they stopped working, but up until then we couldn't detect a failure. This includes PoE VoIP phones -- they work fine until their lease is up, at which point they're done. I've noticed this on the above-mentioned Linksys, three varieties of 3Com, and possibly half a dozen dumb switches. What is it about DHCP that makes it sensitive to failing switches?

• Stuttery 1080p playback on decent system

  - by Leo

  We have a media center system that was recently built. It works well for all types of content, however it has issues with 1080p content. 720p plays fine. I have tried VLC, ffdshow and finally, CoreAVC. CoreAVC plays the best however it still eventually loses sync due to stutter - this does not happen on other systems with the same file. Specs: Asrock 4core-2dual sata PCI Express ATI 2400 HD 1.5GB DDR 2100 Intel Pentium E5300 120GB Maxtor Diamondmax PATA Any ideas?

• dual/multi-boot computers and software licensing

  - by Matt

  Suppose you have a computer with two or more operating systems, and a certain piece of software whose license terms allows it to be installed on one computer, and it does a daily check with a remote server to verify that your serial is only used on the original install computer. You install this software on each of your OSes, but since its a different OS the remote server would have to determine that it is not on the same computer, and so would disable your license. So my question, when a license refers to a single computer, does a situation like this usually count as a single computer, or do the multiple OSes sort of make it multiple computers? How do you think a software vendor (specifically thinking AV companies that do this sort of serial check) would handle this situation?

• Remote kill, upload, execute file

  - by Masoud M.

  I'm developing a program and I need to upload my xyz.exe file to many host machines and execute them frequently. I need a server-client tool to do it as below steps after an update signal from my PC: Those host machine should kill any running processes with name xyz.exe. Download my new xyz.exe. Then execute new xyz.exe. I know about some tools like PsExec, but I need a tools with better user-interface and more powerful. Is there any tool to do it ? UPDATE: The systems are in a same LAN, OS is windows (XP or 7), No full remote access is needed. I'm a developer and my program should run in remote hosts and I'm testing my application.

• Windows 7 - Add folder to Explorer Favorites navigation pane from the Command Line

  - by nondescript1

  In Windows 7 is there a way to add a location to the Explorer Favorites navigation pane from the command line? I'm working with systems that are frequently re-imaged, and I would like to automate adding a number of favorite folders to explorer. I imagine these favorites are also stored in the registry. If someone knows where, I could probably automate managing them through the reg command, although this is less than ideal. I've looked at a number of locations related to explorer suggested here, but haven't found them yet. For information on customizing the favorites section of the navigation pane with Explorer, see http://www.howtogeek.com/howto/10357/add-your-own-folders-to-favorites-in-windows-7/

• Outlook 2010 Error

  - by Trevor Sullivan

  I'm running Outlook 2010 SP1 on Windows 7 x64 SP1, and I'm getting an error message saying "Your Microsoft Exchange administrator has blocked the version of Outlook that you are using. Contact your administrator for assistance." I'm still able to log into my account using Outlook Web Access (OWA), so I know that my account is working just fine. Outlook 2010 with Service Pack 1 is the standard for Windows 7 client systems at this organization, and other people are able to access their e-mail just fine. When my account was initially configured, I was able to use Outlook for a couple of days, and then it suddenly stopped working, providing only the above error message. Do you have any ideas on what I should look into to resolve this problem? Is there any information I can obtain on the client side that will help the Exchange folks investigate the issue further? Is there any verbose logging I can enable, or diagnostic logging in Outlook? Cheers

• Debian: Firefox or Iceweasel default printer for POS station

  - by Bubnoff

  Context Using Debian 6.04 "Squeeze" as POS station. There are two printers installed: Network printer and a receipt printer It absolutely must be able to print by default to the receipt printer on a certain website though the system default is a network printer. In Debian ...it doesn't. Problem I've set up XP, 7, Ubuntu and even Mac OSX this way, so I'm no stranger to setting Firefox up this way ...same Iceweasel/Firefox settings ...complete fail. Always uses system default no matter what the settings, or, which printer you print from. To get this to work on other systems you do this: Print a page in Firefox using desired printer. Ensure print.save_settings is true. Firefox remembers last printer used Set print.always_print_silent = true The end. This works on every OS I've set up ....except Firefox and Iceweasel in Debian. My only recourse seems to be to set the receipt printer as default or go back to bloaty Ubuntu/Mint ...etc.
