  • Broadcom 4365 wireless driver on 12.04 with 3.4 / 3.5 kernel

    - by zaid
    I used this package to install the driver on 3.2 Kernel and it was working perfectly. Unfortunately the system used to freeze randomly with 3.2 kernel so I installed 3.4 kernel, now there is no freezing, the only problem is that my wifi card is not working, I tried to re-install the package, but didn't work. I can see the driver in the "additional drivers" and it say that it is active, but when I execute iwconfig it doesn't show up. I've even tried ndiswraper and that didn't work either. my lspci: 01:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01)

  • Upgraded users to Win7. Now getting "path not found" when saving files or opening attachments

    - by Matt Penner
    We have a Server 2008 AD environment with about 5k users. We just rolled out Windows 7 SP1 (were XP) with great success. However, about once a day we get a few calls that a user opens a file from their Documents (the folder is on the server and redirected), edits it and attempts to save but Win7 reports that the path is not found either because it doesn't exist or no permissions. The only way to fix it is to delete the profile. In addition we get about the same number but different users saying that they cannot open attachments from Outlook 2010 due to no permission. We have to edit the temp Outlook storage path in the registry to fix it (or delete the profile). I think the two issues may be related. What scares us is that we rolled out 1 month ago and had no calls of this nature until about 2 weeks ago. It started off as one or two but seems to be growing. Any ideas? We're going to open a Microsoft ticket but I wanted to seenif anyone else has run into this. Thanks!

  • ubuntu 11.10 CellC data card

    - by Armien
    In 11.10 I find that I can connect to the internet via broadband connection successfully. The problem is that I cannot have the data card attached to the machine while the machine boots up. If I leave the data card in the machine during startup, the data card is not picked up and I then cannot connect to the internet. I must first boot up my machine, login, attach the data card into the usb port, wait so 30 seconds. The broadband connection name will then appear in the network dropdown at the top of the screen. An internet connect is now possible via broadband. Please let me know what must be done to fix this. Thanks Armien

  • How to install Edubuntu on a system with low memory (256 Mb)?

    - by int_ua
    I'm preparing an old system with 256 Mb RAM to send it to some children. It doesn't have Ethernet controller and there are no Internet access at the destination. I've chosen Edubuntu for obvious reasons and modified it with UCK trying to minimize memory usage just to install, let alone using it yet. But Ubiquity won't start even in openbox (edited /etc/lightdm/lightdm.conf) because there are no space left on /cow right after booting. I've already deleted things like ibus, zeitgeist, update-manager (no network access after all), twisted-core, plymouth logos. I'm thinking about creating a swap partition on HDD, can it be later added to expand this /cow ? Is there a package for the text-mode installation which is used on Alternate CDs? I don't want to re-create Edubuntu from an Alternate CD. This behavior is reproducible in VM limited to 256Mb RAM.

  • Learning low latency C++ and Java?

    - by user997112
    I'm currently in a role where I dont get to write any C++ or Java. However, the role is good because provides me with exposure to the business side (i'm interested in finance). Eventually I would like to get into high frequency trading infrastructure. Therefore, outside of work hours i'd like to maximise the knowledge I can gain about high performance Java and C++. I already have the Java Performance Tuning book, which is ok but not impressive. Can people recommend anymore latency blogs/books/websites for learning about making C++/C/Java or even Unix very fast? Or perhaps making the network parts of the OS (if re-writing Unix components) faster? EDIT: Or perhaps we could make this THE thread for advice on writing fast code

    - by Keith
    I installed 12.10 from usb onto this machine. Intel celeron 2.00 GHz 496MB RAM I had to modify GNU-Grub to read "nomodeset" or i could not see the GUI. I have an Nvidia graphics card. Takes about 2 minutes to boot. The icons on the left of desktop take about 1 min to slowly open their menu. Have a network connection but mozilla is 404 and i cannot update. Where can i find a blow by blow explanation for troubleshooting and repairing this problem?

  • Advice on how to understand in general and in practice IT Infrastructure

    - by Luca
    My IT knowledge resides mainly in SW development. I have just some basic know how about networks. On the net I tried to get information and read books in order to better understand the overall IT infrastrcuture, but all the sources I found are too generic or, mainly, too detailed in just one aspect, making me lost. Could anyone suggest some books or web resources as good compromise in details? My goal would be able to understand the network issues and security threats when, for example, two remote system have to be setup and put in connection each other. Considering this scenario there are several aspects to consider: firewalls, intranet/internet interconnections, certificates for httpS, etc. The argument is quite wide, therefore I was looking for something that might help to start to understand this subject without going too deep in details (Computer Networks from A.Tanenbaum is a wonderful milestone, but way too specific for my scope). Thanks

  • How much configurability to give to users regarding concurrency?

    - by rwong
    This question is a narrowing-down of these related questions: How much effort should we spend to programming for multiple cores? Concurrency: How do you approach the design and debug the implementation? Given that each user's computers may have different performance characteristics with respect to calculations, memory, disk I/O bandwidth and network I/O bandwidth, and that it is difficult to implement an automated self-tuning system in your software, how much configurability should we give to the end-users so that they can find ways (by trial-and-error?) to improve our software's efficiency? If we give users the ability to change these settings, how do we give visual feedback to users so they can measure the performance changes?

  • What is the career path for a software developer/ programmer? [closed]

    - by Lo Wai Lun
    I've been working as a programmer for a few months and I often study CCNA , CISSP for future. Besides simple coding I was working on specs, designing applications, and all those around-like things. My question is, I want to be a information / system security specialist. what's the career path I should be aiming for? Is it like working on code for the rest of my life? :) Restart my career from the network engineer ? Or do programmers make a good manager-position people ? I know it's very subjective. Thing is, lately I find myself much more into the designing/working on specs part of the development project then the coding itself. How do you see it? Would you like to go from development to information security? Would you like to work on a project with a manager that used to be a coder?

  • Server 2003 and SSL Certificates

    - by Keith Stokes
    I have a Windows 2000 domain with dozens of Windows 2000 servers and a few 2003 servers. Each server runs a custom app talking to a 3rd party utilizing self-signed certificates. To help troubleshooting we've created a custom test app. The 2000 servers are able to talk within seconds. The 2003 servers take anywhere from 10-30 seconds using a domain account and much less, usually under 5 seconds using a local account. The only exception to the local account performance is a new account, which is slow initially then faster. If you leave the test app open and reconnect repeatedly it talks in seconds. If you leave it open for sometime between 1 and 2 hours, it reverts back to the previous 10 seconds, so obviously something is caching. Installing the destination certificates in the local 2003 server store makes no difference. I've installed the certificates in AD and that apparently makes domain accounts work in 9-12 seconds, vs 30 seconds that was regular before. Manually clearing the certificate store on the 2003 server makes no difference. I'm at a loss as to where the certs might be cached and if I'm using some sort of domain certificate store that's hiding from me.

  • Retrieve a user's Exchange database in powershell

    - by Paul
    Hey Everyone, I've scoured the interwebs for a few days now off and on to find this. I am creating a powershell script for email-enabling new user's(Exchange 2007). To give you a little background when we have a new hire, their AD account is created at our off-site helpdesk, but they don't create their email account. I'm trying to automate the process of mail-enabling the user which involves putting them in the same database as an existing user, disable imap pop activesync, and lastly email the requester of the ticket. I would like to just get prompted for the New User's name, User to Replicate(mailbox, storage group, database), and the person to email after it's been created. So if someone could just help with a command to Retrieve a user's Exchange database in powershell that would be great, but if people also want to help with my hacked up script please do so as well!!! Here is what I have so far: Write-output “ENTER THE FOLLOWING DETAILS” $DName = Read-Host “User Diplay Name" $RUser = Read-Host "Replicate User(Database Grab)" ***$RData = #get the Replicate user's mailbox database here*** $REmail = #either just use a Read-Host “Requester's Email address" or ask for Requester's name and pipe through their email address by digging for it w/ powershell Enable-Mailbox -Identity "$DName" -Database "$RData" Send-MailMessage -From "John Doe <[email protected]>" -To (put $REmail here which is the Requester's email) -Subject "Test Person's email account" -Body "Test Person's email account has been setup.`n`n`nJohn Doe`nGeneric Company`nSystems Administrator`nOffice: 123.456.7890`[email protected]" -SmtpServer genericexchange.exchange.com

  • Covering Yourself For Copyrighted Materials [on hold]

    - by user3177012
    I was thinking about developing a small community website where people of a certain profession can register and post their own blogs (Which includes an optional photo). I then got to thinking about how people might use this and the fact that if they are given the option to add a photo, they might be likely to use one that they simply find on Google, another social network or even an existing online blog/magazine article. So how do I cover myself from getting a fine slapped on me and to make it purely the fault of the individual uploader? I plan on having an option where the user can credit a photo by typing in the original photographers name & web link (optional) and to make them tick a check box stating that the post is their own content and that they have permission to use any images but is that enough to cover myself? How do other sites do it?

  • How to connect to the internet reliably

    - by user12689
    I have a DSL internet connection. For a long time the internet functioned fine in Ubuntu using the default Network Manager. Recently however, my ISP was bought by another ISP, and the service name had to be changed in the DSL settings. In Windows, it connects without any issue whatsoever. But in Ubuntu, the first time I connect I get a "Apache: Not Found" page, the next time, I get to the previous ISP's login page, it continues like this for some time until I get it working. I have to try connecting it again and again. When I asked the customer service, they said that because of the takeover, they have switched servers. But they said, it should work properly in Windows, and they were clueless about Ubuntu. Is there anything I can do to solve this issue?

  • My very first serious project and I'm concerned about security.

    - by ilhan
    I'm making a small social networking web site for a specific university's students (where I study) and I'm concerned about security (access to the database). What should I do? What I have to check for last time until I went online? (Yeah, Facebook Facebook. Facebook don't have that community sense. You cannot find all your department mates on Facebook. You cannot see all foreign students on Facebook. You cannot hide your identity on Facebook while commenting, etc etc. Just please don't compare it with Facebook, we had a great local social network until it went public . * ))

  • HTG Explains: Live File System vs. Mastered Disc Formats in Windows

    - by Chris Hoffman
    When burning a CD or DVD with Windows, you’ll be asked whether you want to use a Live File System or a Mastered disc format. Each has its own advantages and disadvantages. Windows 7 refers to this as “Like a USB flash drive” or “With a CD/DVD player.” But how exactly can a non-rewritable disc function like a USB flash drive?

  • Using Active Directory through a Firewall

    - by Adam Brand
    I had kind of a weird setup today where I wanted to enable Windows Firewall on a Windows 2003 R2 SP2 computer that would act as an Active Directory Domain Controller. I didn't see one resource on the Internet that listed what would be required to do this, so I thought I'd list them here and see if anyone has anything to add/sees something that isn't necessary. Ports to Open with "subnet" scope: 42 | TCP | WINS (if you use it) 53 | TCP | DNS 53 | UDP | DNS 88 | TCP | Kerberos 88 | UDP | Kerberos 123 | UDP | NTP 135 | TCP | RPC 135 | UDP | RPC 137 | UDP | NetBIOS 138 | UDP | NetBIOS 139 | TCP | NetBIOS 389 | TCP | LDAP 389 | UDP | LDAP 445 | TCP | SMB 445 | UDP | SMB 636 | TCP | LDAPS 3268 | TCP | GC LDAP 3269 | TCP | GC LDAP Ports to Open with "Any" Scope (for DHCP) 67 | UDP | DHCP 2535 | UDP | DHCP ALSO You need to restrict RPC to use fixed ports instead of everything 1024. For that, you need to add two registry keys: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters Registry value: TCP/IP Port Value type: REG_DWORD Value data: <-- pick a port like 1600 and put it here HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters Registry value: DCTcpipPort Value type: REG_DWORD Value data: <-- pick another port like 1650 and put it here ...don't forget to add entries in the firewall to allow those in (TCP, Subnet scope). After doing all that, I was able to add a client computer to the AD domain (behind Windows Firewall) and log in successfully.

  • How do I get my RTL8192ce based wireless device working properly?

    - by JonnyTruelove
    I am using the rtl8192cu chipset (on a Belkin wireless USB adapter N300) combined with 64 bit architecture and the 3.8 kernel. Some of you may know that this doesn't work. I tried this fix - RTL8188CU USB Network Adaptor on ubuntu 13.04 and now my internet is super slow. I am totally new to Ubuntu and I am concerned I do not have the right driver. The "stock" driver was the RTL8192cu, but it didn't connect 99% of the time and if it did the upload speed was higher than the download. Right now I am connecting through my laptop with a crossover cable, so my internet connection is just fine in my apartment. Relevant output from lsusb is here: Bus 002 Device 002: ID 050d:2103 Belkin Components F7D2102 802.11n N300 Micro Wireless Adapter v3000 [Realtek RTL8192CU] (bonus question: is that [050d:2103] the actual physical address straight from the hardware? Or does it change when I put different drivers on it? I am concerned I do not have the right driver)

  • Design a Distributed System

    - by Bonton255
    I am preparing for an interview on Distributed Systems. I have gone through a lot of text and understand the basics of the area. However, I need some examples of discussions on designing a distributed system given a scenario. For example, if I were to design a distributed system to calculate if a number N is primary or not, what will the be design of the system, what will be the impact of network latency, CPU performance, node failure, addition of nodes, time synchronization etc. If you guys could present your in-depth thoughts on this example, or point me to some similar discussion, that would be really helpful.

  • Can't ping external websites

    - by Frantumn
    I can't ping google.com with my virtual ubuntu 12.04 server. I have set up a proxy URL in my /etc/apt/apt.conf file and it says Aquire::http::proxy http://urlname.com:9999; Now, I don't know a lot about how the proxy works, but I do know when we use it on windows VMachines it's a pac script that we place in internet explorer LAN settings and it automatically detects the script and gives internet access. I tried including the 9999/proxy.pac in the apt.conf URL and it didn't seem to work any better. Would ubuntu know how to handle a proxy.pac assuming it was created for windows? Should my URL include the .pac or just end after the port numbers? I've tried both without sucess, but I would like to know. A quick test to ping a fellow co-workers' PC was sucessful. So I can see network computers, but not google. or other internet sources.

  • We Heart Discussion Forums (and Know You Do Too)

    - by oracletechnet
    It's not generally known, but Oracle (via Oracle Technology Network) hosts one of the largest discussion forums instances (forums.oracle.com) on the planet (founded in 2001), containing nearly 10 million messages from 1 million registered users. That's a whole lot of conversations! And we really, really value those conversations - they span almost every conceivable technical subject across hundreds of products and technologies. More often not - and this is by design - those discussions are stewarded by community volunteers, many of whom are Oracle ACEs (who in fact earned their ACE stripes that way). And so, I am very happy to tell you that we have just initiated a project with our platform partner, Jive Software, to upgrade that platform to the most current, modern version available. The end result should be a vastly improved user experience for everyone involved, in all dimensions. There are many, many details to work on in coming weeks, but we'll keep you posted - and, when needed, come back to you for advice and suggestions. For now, we just wanted to share the good news!
