• How to Find Out Which Devices Are Supported By Solaris 11

  - by rickramsey

  Image of monks gathering on the steps of the main hall in the Tashilhunpo Monastery is courtesy of Alison Whitear Travel Photography. In his update of Brian Leonard's original Taking Your First Steps With Oracle Solaris, Glynn Foster walks you through the most basic steps required to get a version of Oracle Solaris 11 operational: Installing Solaris (VirtualBox, bare metal, or multi-boot) Managing users (root role, sudo command) Managing services with SMF (svcs and svcadm) Connecting to the network (with SMF or manually via dladm and ipadm) Figuring out the directory structure Updating software (with the IPS GUI or the pkg command) Managing package repositories Creating and managing additional boot environments One of the things you'll have to consider as you install Solaris 11 on an x86 system is whether Solaris has the proper drivers for the devices on your system. In the section titled "Installing On Bare Metal as a Standalone System," Glynn shows you how to use the Device Driver utility that's included with the Graphical Installer. However, if you want to get that information before you start installing Solaris 11 on your x86 system, you can consult the x86 Device List that's part of the Oracle Solaris Hardware Compatibility List (HCL). Here's how: Open the Device List. Scroll down to the table. Open the "Select Release" pull-down menu and pick "Solaris 11 11/11." Move over to the "Select Device Type" pull-down menu, and pick the device type. Or "All." The table will list all the devices of that type that are supported by Solaris 11, including PCI ID and vendor. In the coming days the Solaris Hardware Compatibility List will be updated with more Solaris 11 content. Stay tuned. - Rick Ramsey Website Newsletter Facebook Twitter

• Ricoh Aficio 1515ps - How can I get the scanner to scan? (printing works)

  - by nutty about natty

  For similar screenshots and story, see: How to define my Samsung SCX3200 multifunction printer? and for a possible solution: How can I get an Epson TX560WD scanner working? Thanks! Edit n°1 installed xsane (via Ubuntu Software Center), launched it and get the following: Clicking on "Help" yields: I tried 4) man sane-dll which yields No manual entry for sane-dll I uninstalled "Simple Scan": didn't help. I tried 3) but aborted due to unsettling warning ;) wasn't that brave (or desperate). Maybe it's due to 1) and I'm stuck with it? Is it really not possible that a driver for either Windoze or Mac OS would also support scanning via Ubuntu? Edit n°2 Resorted to Windows XP and the Network TWAIN Driver ScanRouter or the "lite" version (which I found elsewhere) might also work (under Linux??); but it's more than I need. Thought about WINE, but also that seems to rely on SANE... So still no luck with this device's scanning capabilities with Linux (but good enough (via xp) for my purposes)...

• What's the likely culprit in email delay?

  - by Kiki

  If anyone can shed light or point me to a tutorial, I'd appreciate it. We are a tiny company and have experienced occasional delays in receiving email sent between staff members. We are in separate cities but all in the same state; our webhost/email ISP is across the country from us. If it matters, we're on Macs and most of use Entourage. Our email configurations are POP server: companyname.com and SMTP: smtp.companyname.com (When we used our DSL providers for SMTP we had unreliable service) Our ISP says they're not seeing delays related to their equipment and the problem is elsewhere in the network. A co-worker believes that the delays are with the ISP. Is there a good way to figure this out?

• How to setup a host as a sendmail relay for particular IP subnet

  - by Abhinav

  Hi, By default, sendmail (I have version 8.13 on an RHEL4) allows only local mails. I wanted to allow mails from a particular network to be relayed via the system, so I did the following based on suggestions from various places : /etc/mail/access : Added the subnet and the domain 8.37 RELAY mydomain.com RELAY (I assume this is the originating email's domain) This alone did not work, so I added the following to sendmail.mc FEATURE(access_db)dbl Now, the problem is that it is allowing access from other domains as well. To test it out, I removed 8.37 RELAY from the access, and changed the email from field to [email protected] However, I still receive the mail. What is the correct way to configure this, so that only mails from a particular subnet are relayed ?

• Talking JavaOne with Rock Star Adam Bien

  - by Janice J. Heiss

  Among the most celebrated developers in recent years, especially in the domain of Java EE and JavaFX, is consultant Adam Bien, who, in addition to being a JavaOne Rock Star for Java EE sessions given in 2009 and 20011, is a Java Champion, the winner of Oracle Magazine’s 2011 Top Java Developer of the Year Award, and recently won a 2012 JAX Innovation Award as a top Java Ambassador. Bien will be presenting the following sessions: TUT3907 - Java EE 6/7: The Lean Parts CON3906 - Stress-Testing Java EE 6 Applications Without Stress CON3908 - Building Serious JavaFX 2 Applications CON3896 - Interactive Onstage Java EE Overengineering I spoke with Bien to get his take on Java today. He expressed excitement that the smallest companies and startups are showing increasing interest in Java EE. “This is a very good sign,” said Bien. “Only a few years ago J2EE was mostly used by larger companies -- now it becomes interesting even for one-person shows. Enterprise Java events are also extremely popular. On the Java SE side, I'm really excited about Project Nashorn.” Nashorn is an upcoming JavaScript engine, developed fully in Java by Oracle, and based on the Da Vinci Machine (JSR 292) which is expected to be available for Java 8.   Bien expressed concern about a common misconception regarding Java's mediocre productivity. “The problem is not Java,” explained Bien, “but rather systems built with ancient patterns and approaches. Sometimes it really is ‘Cargo Cult Programming.’ Java SE/EE can be incredibly productive and lean without the unnecessary and hard-to-maintain bloat. The real problems are ‘Ivory Towers’ and not Java’s lack of productivity.” Bien remarked that if there is one thing he wanted Java developers to understand it is that, "Premature optimization is the root of all evil. Or at least of some evil. Modern JVMs and application servers are hard to optimize upfront. It is far easier to write simple code and measure the results continuously. Identify the hotspots first, then optimize.” He advised Java EE developers to, “Rethink everything you know about Enterprise Java. Before you implement anything, ask the question: ‘Why?’ If there is no clear answer -- just don't do it. Most well known best practices are outdated. Focus your efforts on the domain problem and not the technology.” Looking ahead, Bien said, “I would like to see open source application servers running directly on a hypervisor. Packaging the whole runtime in a single file would significantly simplify the deployment and operations.”Check out a recent Java Magazine interview with Bien about his Java EE 6 stress monitoring tool here.

• How do I resolve active directory connection errors when using dcpromo?

  - by Middletone

  When attempting to promote a secondary server to an existing active directory forest I receive the following error message and can no longer continue. Failed to examine the active directory forest. Value ridMasterDSA.partentDN not found What can cause this and what can be done to fix it? Both servers are 2008 running on x64 and can see each other on the network via their names. FYI: The firewall is turned off on both machines so there should be no issue there. Also the server that i'm adding is already a part of the domain. One server is already a domain controller but I want to add a second to it.

• Turnkeylinux lampp guest doesn't have internet connection

  - by dave08

  I've set up a turnkeylinux lampp server in virtualbox with two network bridged connections, one for when I'm plugged in to my router, and one for when I'm using a wireless connection. This allowed me to pull up the turnkey control panel on the host machine's browser, but when I try going into the command prompt in the guest and run an apt-get update, it doesn't seem to have an internet connection, even though it seems to have a connection with the host. What could be wrong? Thank you very much in advance for any answers...!

• Ask the Readers: How Fast is Your Internet Connection?

  - by Mysticgeek

  The federal government recently announced a broadband initiative that calls for 260 million homes to have 100Mbps Internet connections by the year 2020. This got us wondering, how fast is your current Internet connection? Photo by roland When it comes to the speed of our Internet connection, we all want the maximum possible. The FCC recently announced their National Broadband Plan, which is an initiative to improve the Internet infrastructure in the United States and provide higher speeds to everyone. You’ve also undoubtedly heard the news about Google getting into the mix with their program to bring ultra high-speed fiber broadband to 50,000 users in select cities. While we wait for those programs to come into fruition, we thought it would be cool to check out what kinds of speeds you’re getting now. Test Your Internet Connection Speed There are several sites out there you can use to test your Internet speeds, but probably the best site is Speedtest.net. It’s easy to use, and allows you test download and upload speeds to and from various locations in the US and throughout the world. If you already know the speeds you’re getting leave a comment and let us know. If you use Speedtest.com, just keep in mind that our comment system won’t allow you to copy their result links, but you can simply tell us what you get in the results. We’re especially interested in the results of those of you who have Verizon FIOS or Comcast’s “Ultra” service. Leave a comment and join in the discussion!

• Are there any FIPS-140-2 certified solutions for Linux?

  - by Mark Renouf

  I'm not even 100% certain what this involves, but my current understanding is this: use of only approved cryptographic algorithms for network traffic (easy, we use SSL and lock down the algorithms to only the really strong ones). Some form of physical data protection, involving disk encryption and physical tamper evident packaging. Obviously we're on our own if we need a tamper-proof product. But what about software for encrpytion. My guess is just using LUKS (although secure) will not be certified because it's open source (gov't seems a bit biased towards proprietary solutions here). Guardian Edge was mentioned by someone, but that appears to be complete Windows-based. So we need something like it, certified FIPS-140 compliant we can use on Linux.

• How can I edit local security policy from a batch file?

  - by Stephen Jennings

  I am trying to write a utility as a batch file that, among other things, adds a user to the "Deny logon locally" local security policy. This batch file will be used on hundreds of independent computers (not on a domain and aren't even on the same network). I assumed one of the following were my options, but perhaps there's one I haven't thought of. A command line utility similar to net.exe which can modify local security policy. A VBScript sample to do the same. Write my own using some WMI or Win32 calls. I'd rather not do this one if I don't have to.

• July, the 31 Days of SQL Server DMO’s – Day 3 (sys.dm_exec_connections)

  - by Tamarick Hill

    The third DMV we will review is the sys.dm_exec_connections DMV. This DMV is Server-Scoped and displays information about each and every current connection on your SQL Server Instance. Lets take a look at some information that this DMV returns. SELECT * FROM sys.dm_exec_connections After reviewing this DMV, in my opinion, its not a whole lot of useful information returned from this DMV from a monitoring or troubleshooting standpoint. The primary use case I have for this DMV is when I need to get a quick count of how many connections I have on one of my SQL Server boxes. For this purpose a quick SELECT COUNT(*) satisfies my need. However, for those who need it, there is other information such as what type of authentication a specific connection is using, network packet size, and client/local TCP ports being used. This information can come in handy for specific scenarios but you probably wont need it very much for your day to day monitoring/troubleshooting needs. However, this is still an important DMV that you should be aware of in the event that you need it. For more information on this DMV, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms181509.aspx

• Remote connection IP to use

  - by petwho

  I have two laptops that both run on ubuntu and installed ssh server and ssh client on them. One is usually on my desk at home and one I usually bring to my company. When I'm at home I can easily ssh to one from the other by typing this command (to login to the other laptop whose IP address is: 192.168.0.105) : ssh -p 22 [email protected] However, When I'm at my company, I try to type the same command and ofcourse it doesn't work. I understand that when at home I'm on LAN network, that my laptops actually using my ISP's address which differ from 192.168.0.107 asummed 203.113.131.1. So could you tell me what IP that ssh shoud use for my laptop (at work) to connet to my computer at home? Thank you.

• Child Folder inheriting a permission that parent folder does not have (NTFS)

  - by just.another.programmer

  I'm reconfiguring roaming profiles on my network to use proper NTFS security settings according to this article. I have reset the following permissions on the roaming profile parent folder: CREATOR OWNER, Full Control, Subfolder and files only User group with profiles, List folder, Create folders, This folder only System, Full Control, This folder, subfolders, and files Then I select one of the actual roaming profile folders and follow these steps to fix the NTFS settings: Click Security, Advanced Uncheck "Allow inheritable permissions..." Choose "Remove..." Recheck "Allow inheritable permissions..." Click "Apply" After I choose apply, I get the following permissions listed on the roaming profile folder: Administrators (MYDOMAIN\Administrators) Full Control, This folder only CREATOR OWNER, Full Control, Subfolders and files only System, Full Control, This folder, subfolders, and files Where is the Administrators entry coming from!? There is an entry on the root of the drive for Administrators to have full control, but the Roaming Profile Parent folder is not set to inherit any permissions, and it does not have the administrators permission.

• Configuring WPA2-Enterprise with Freeradius

  - by Vincent O.

  I'm trying to set up an authenticated wifi network with Freeradius. I've managed to get things working using self-signed certs etc. The problem is Windows clients need to uncheck the "Automatically use my windows logon name and password [etc.]" option in the MSCHAPv2 settings. When I connect to my local university with Eduroam, it automatically asks for a username and password instead of sending windows login credentials. How did the sysadmins accomplish this? Is it some kind of RADIUS Attribute that gets sent back?

• Components needed for a VPN

  - by Anriëtte Combrink

  Hi there, first of all, I asked this question on SuperUser.com, but no one there could help me. Well, we eventually got our Mac Mini Server. We now want to set up a small Remote Access VPN using this Mac Mini Server. Firstly we are not sure of the components needed additionally to the server to setup this VPN. We currently have the following: 1 Mac Mini Server 1 Firewall Router (Billion 802.11g ADSL2+ router with VPN capabilities [it says so on the box]), we currently use this as our internet connection and resides X.X.0.1 on our network. 4Mbps ADSL connection (Should this line have VPN capability enabled by the service provider?) We are not sure what else needs to be included to enable our small VPN. Any advice would be really helpful?

• accessing a web server from the LAN and WAN

  - by jessh

  My router does not support loopback. In order to view a webpage on my server, I either have to type in the local ip (192.168.1.201), or be on another network. What are my options for making this easier? Here are some possible things: Route all web traffic through an external proxy (seems to be overkill) Run my own DNS server (where to start?!) Buy a new router that supports loopback. Surely there is another way that I can use my laptop on the LAN and the WAN by typing in my domain more easily than these solutions.

• Set certain WSUS updates to auto-install

  - by Nicolas

  We're running a WSUS server for the simple purpose of caching updates. Since we are a very small network of all "power users", we've got the domain group policy for WSUS updates on the clients set to prompt for download/install. i.e. We don't want updates to install without our knowledge. But there are a few cases where it would be nice to be able to set a certain update to auto-install. e.g. Windows Defender updates, Malicious Software Removal Tool, Outlook Junk Email Filter, etc. Basically all the silly little updates that you would always install anyway and don't require a restart. Is there a way to set the general policy to prompt for download/install, but auto-install certain regular updates? P.S. WSUS itself does have the facility to auto-approve certain updates. That part works. Facts & Figures: SBS 2003 domain Windows 7 Pro clients Windows XP Pro clients

• Browsers not responding

  - by Jesper

  Hello, Strange thing started to happen to my computer yesterday, and I can not recall installing anything new or updating anything the last few days either. It was first the browser, Chromium, that started to freeze up and not respond for ages, say 10 minutes. Then my email, Windows Live Mail client started doing the same thing, I click on an email and the program goes "not responding" for 5-10 minutes. At first I thought it was Chromium, so i reinstalled it but no help, So i installed Opera and thought I would give it t a try, but not same thing is happening to Opera so it is clearly an OS issue or/and internet connection issue. Does anyone know what the problem can be? Im running Windows 7 32bit on a dual core Sony vaio laptop with 4gb ram. There is nothing wrong with the actual internet connection as it works fine on other computers on the network, and the connection it self does not drop. Grateful for any help, Jesper

• Static IPv4 and dynamic IPv6 on same interface

  - by Zsub

  I am trying to set up a CentOS 5.4 box to use a static IPv4 address, while getting a dynamic IPv6 address at boot time. I have only one interface, apart from the loopback interface, eth0. It has a static v4 and internet connectivity (I can SSH in). However, it doesn't get an IPv6 by default. I have enabled IPv6 in /etc/sysconfig/network and I have added IPV6INIT=yes to the config in /etc/sysconfig/networking/devices/. If I use dhcp6c it does get a valid IPv6 address, but the main question is how do I configure it to get one at boot-time?
