• Don't Use Static? [closed]

  - by Joshiatto

  Possible Duplicate: Is static universally “evil” for unit testing and if so why does resharper recommend it? Heavy use of static methods in a Java EE web application? I submitted an application I wrote to some other architects for code review. One of them almost immediately wrote me back and said "Don't use "static". You can't write automated tests with static classes and methods. "Static" is to be avoided." I checked and fully 1/4 of my classes are marked "static". I use static when I am not going to create an instance of a class because the class is a single global class used throughout the code. He went on to mention something involving mocking, IOC/DI techniques that can't be used with static code. He says it is unfortunate when 3rd party libraries are static because of their un-testability. Is this other architect correct?

• wakeonlan from remote host

  - by takeshin

  I have setup wake on lan service on my server. Everything works fine on local area network: root@server$: poweroff user@local$ wakeonlan AA:BB:CC:DD:EE:FF and the server wakes up. AA:BB:CC:DD:EE:FF is a MAC address of my server, which has IP 192.168.1.2 and hostname: example.com. It is connected to the router, which has IP 192.168.1.1 (public: xxx.xxx.xxx.xxx) When the server is up, I can ping: ping example.com or login via ssh: ssh [email protected] So far, so good. Now I'm able to wake the server up from local area, but how to wake the server from the remote location? I tried: user@local$ wakeonlan -i xxx.xxx.xxx.xxx AA:BB:CC:DD:EE:FF, but it does not work (nothing happens;). Do I have to configure my router somehow to forward magic packets? How?

• The Threats are Outside the Risks are Inside

  - by Naresh Persaud

  In the past few years we have seen the threats against the enterprise increase dramatically. The number of attacks originating externally have outpaced the number of attacks driven by insiders. During the CSO Summit at Open World, Sonny Singh examined the phenomenon and shared Oracle's security story. While the threats are largely external, the risks are largely inside. Criminals are going after our sensitive customer data. In some cases the attacks are advanced. In most cases the attacks are very simple. Taking a security inside out approach can provide a cost effective way to secure an organization's most valuable assets. &amp;amp;amp;lt;/span&amp;amp;amp;gt;border-width:1px 1px 0;margin-bottom:5px&amp;amp;amp;quot; allowfullscreen=&amp;amp;amp;quot;&amp;amp;amp;quot;&amp;amp;amp;gt; Cso oow12-summit-sonny-sing hv4 from OracleIDM

• Error 1130 connecting to MySQL on Ubuntu Server 12.04

  - by maGz

  I hope this is the right place for this...I currently am running Ubuntu Server 12.04 through VirtualBox on a Windows 7 host. I am trying to connect to the VM's MySQL engine using MyDB Studio for MySQL, and when I enter my MySQL login credentials, it gives me the following error back: Error 1130: Host '192.168.56.1' is not allowed to connect to this MySQL server I am running the VM with Adapter 1 enabled for NAT, and Adapter 2 enabled for Host-only Adapter. eth0 10.0.2.15 and eth1 192.168.56.21. I can connect to Apache at 192.168.56.21, and through PhpMyAdmin, everything works as it should. I did edit the /etc/mysql/my.cnf file and commented out the line bind-address = 127.0.0.1 by adding a # in front of it - I thought that this should have allowed remote connections. Any ideas on how I can solve this? What could be wrong? EDIT: I am trying to connect as 'root'. EDIT: SOLVED!!

• Executive Edge: It's the end of work as we know it

  - by Naresh Persaud

  If you are at Oracle Open World, it has been an exciting couple of days from Larry's keynote to the events at the Executive Edge. The CSO Summit was included as a program within the Executive Edge this year. The day started with a great presentation from Joel Brenner, author of "America The Vulnerable", as he discussed the impact of state sponsored espionage on businesses. The opportunity for every business is to turn security into a business advantage. As we enter an in-hospitable security climate, every business has to adapt to the security climate change.  Amit Jasuja's presentation focused on how customers can secure the new digital experience. As every sector of the economy transforms to adapt to changing global economic pressures, every business has to adapt. For IT organizations, the biggest transformation will involve cloud, mobile and social. Organizations that can get security right in the "new work order" will have an advantage. It is truly the end of work as we know it.  The "new work order" means working anytime and anywhere. The office is anywhere we want it to be because work is not a place it is an activity. Below is a copy of Amit Jasuja's presentation. Csooow12 amit-jasuja-securing-new-experience6 from OracleIDM

• How do you set up a ubuntu server so that it can recieve and run code remotely

  - by deadjaguars

  I've gotten my hands on two older (i.e. ~2 years old) department towers that I came across when setting up our new workstations that I want to turn into servers that people can run code on remotely. The code would mostly consist of Python (2 and 3) and Java. Being able to run those is a must, but other languages would be nice. I thought here would be a good as place as any to ask where I would start.

• Cannot move/drag/drop windows/items in remote VNC session

  - by hansioux

  I find it a little hard to believe that no one here has asked this question, I tried searching for it but it isn't asked, so here goes: I setup a Ubuntu desktop computer with VNC to use as a server. And use another Ubuntu desktop computer to VNC into it. The rest of the VNC works ok, but drag and drop with mouse is gone. Thus I can not move windows, or drag and drop items via VNC. I am using the default remote desktop in System - Preferences to setup my server. And use Remmina as my client. The same happens using MS Windows's VNC clients connecting to my Ubuntu desktop. I did a bit of searching on google, and there are actually a lot of reports regarding this issue. But, oddly there is no solution. There are even bug reports made for this since Ubuntu 9.10, yet here it still is in Ubuntu 11.04. There have been suggestions that the bugs is in gtk, as see in link below: http://ubuntuforums.org/showthread.php?t=1497635&page=2 libgtk2.0-0 stable(lenny) -> DnD works libgtk2.0-0 lenny-backport (libgtk2.0-0_2.18.6-1~bpo50+1_i386) -> DnD still works libgtk2.0-0 testing (libgtk2.0-0_2.20.1-2_i386) -> DnD broken please don't give answers such as "use NX", "use ssh -x" or "use x11vnc". I am aware that some people don't have this problem with x11vnc, and I have setup x11vnc before, but i can't for this setup. I am setting this up so Windows only friends/families can use it.

• Script to setup ubuntu as a wireless accesspoint on a bridge mode

  - by nixnotwin

  I use the following script to make my netbook a full-fledged wireless accesspoint. It creates a bridge with eth0 and wlan0 and starts hostapd. #!/bin/bash service network-manager stop ifconfig eth0 0.0.0.0 #remove IP from eth0 ifconfig eth0 up #ensure the interface is up ifconfig wlan0 0.0.0.0 #remove IP from eth1 ifconfig wlan0 up #ensure the interface is up brctl addbr br0 #create br0 node hostapd -d /etc/hostapd/hostapd.conf > /var/log/hostapd.log & sleep 5 brctl addif br0 eth0 #add eth0 to bridge br0 brctl addif br0 wlan0 #add wlan0 to bridge br0 ifconfig br0 192.168.1.15 netmask 255.255.255.0 #ip for bridge ifconfig br0 up #bring up interface route add default gw 192.168.1.1 # gateway This script works efficiently. But if I want to revert back to use Network Manager, I cannot do it. The bridge simply cannot be deleted. How can I modify this script so that if I run bridge_script --stop, the bridge gets deleted, network manager starts and interfaces behave as if the machine had a fresh reboot.

• Takeaways From CSO Roundtable New York

  - by Naresh Persaud

  Thanks to everyone who attended the Chief Security Officer Roundtable in New York last week. We were lucky to have Dennis Brixus, CSO of McGraw-Hill  as a guest speaker. In addition, Jeff Henley, provided a board level perspective on security. Amit Jasuja discussed Oracle's security formula.  A few takeaways from Jeff's talk that were interesting: Security is a board level issue. The challenge at the board level is that boards have short attention span. The CSO needs to be vigilant in educating the board on the strategic importance of security. Every CSO needs to think about cost. The CSO has to look at the economics of security and demonstrate fiduciary responsibility. We have to think of security as a business enabler. Security is the enabler that helps us expand into new markets and connect better with our customers and partners. While the CSO can't prevent every threat, we have to expect the CSO to have a plan.

• Switch encoding of terminal with a command

  - by Tomas Lycken

  One of the servers I quite often ssh to uses western encoding instead of utf-8 (and there's no way I can change that). I've started writing a bash script to connect to this server, so I won't have to type out the entire address every time, but I would like to improve this script so it also changes the encoding of the terminal window correctly. The change I need to do can be performed using the mouse by navigating to "Terminal"-"Set Character Encoding..."-"Western (ISO-8859-1)". Is there a terminal command that does the same thing, for the current terminal window/screen? To clarify: I'm not interested in ways of switching the locale of the system on the remote site - that system is administered by someone else, and I have no idea what stuff might depend on the latin-1 encoding there. What I want to do is to let this terminal window on my side switch character encoding to the above mentioned, in the same way I can do with my mouse and the menus.

• Turning laptop into WAP using netgear WNA1100? (stuck at hostapd)

  - by Vivek Sharma

  I have a Netgear WNA1100 usb wifi adapter. I have installed Atheros driver from Forum Details (btw name of the file is ath9k_htc-installer.1.0.1-maverick-fixed.deb). I wish to make a setup like connectify(windows) on ubuntu, so that I can connect my phone wirelessly to my laptop via Netgear WNA1100 (behaving as AP) and eventually use internet via my wired lan. I have installed the above mentioned driver, hostapd and hostap-utils. Following is my hostapd.conf file. ssid=vks interface=wlan1 # The interface name of the card driver=ath9k_htc # The card driver macaddr_acl=0 accept_mac_file=/etc/hostapd.accept deny_mac_file=/etc/hostapd.deny ieee80211x=1 # Use 802.1X authentication auth_algs=1 ignore_broadcast_ssid=0 wpa=2 wpa_passphrase=88888888 wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP When i run sudo hostapd /etc/hostapd/hostapd.conf I get an error invalid/unknown driver 'ath9k_htc # The card driver I think the driver is installed fine, as i can see the blue led blinking on the netgear adapter, which was not blinking earlier. Can someone please guide me how to achieve this setup? I will appreciate an example hostapd.conf file with a simple wpa_psk security setup. Please be detailed and descriptive with commands. How to run and end it. Following is output from lsmod, i have only pasted the entries which had ath and ath related info. Which driver shall i use.

• FTP over ssh hangs on "Connection established: Waiting for Welcome Message"

  - by Siriss

  I have looked far and wide and have not quite found the answer. I am running ubuntu 11.10, openssh, and vsftpd. I am trying to configure my FTP to tunnel over ssh. My ssh connection works just fine and I can create the tunnel to my FTP port. When I go to use Filezilla to connect, it hangs at "Waiting for Welcome Message". I think it is an iptables issue, but I can't seem to figure out what needs to be changed. When I take iptables down, it connects just fine. I don't want to open any more external ports, just my one SSH port, and I can't seem to get it right on the internal port forwarding rule. I always end up opening it to the outside. I would love some help if anyone has any ideas and I hope I have made it clear. Thank you in advance!!

• Can not get to login screen, background starts with terminal prompt only

  - by Doug

  my uncle has Ubuntu on his work PC. Basically I came in to work today, and he had lost his UNITY side bar. I told him start with just rebooting it. He rebooted it... now it does not even get to the login screen. It gets to the background with the word UBUNTU, and the 6 or 7 dots, does it's little loading dot thing... then stops, and a black terminal opens on the top left with the background still in place. Personally, I think he screwed it up himself. He always swears he didn't touch anything, but I know better... Either way, I can't get him back into the desktop to even see if the sidebar is back. He's always screwing around pressing the wrong buttons on the login screen, hitting admin things and such... Any ideas?

• How to print over ssh?

  - by mit

  I have the following configuration: P == U ---------------- W P is a HP Laserjet, connected to U, which is an Ubuntu 10.04 desktop machine with a standard gnome setup from the live cd. I just selected the HP Laserjet in the gnome printer admin and it works, I can print locally. W is a remote windows machine, server 2003, and --- is an untrusted connection. I wonder if I can create an ssh tunnel between U and W, so W can print using U's printer service. Which ports will I need to forward and what kind of printer must I add then on the windows machine?

• Building an ASP.Net 4.5 Web forms application - part 4

  - by nikolaosk

  ?his is the fourth post in a series of posts on how to design and implement an ASP.Net 4.5 Web Forms store that sells posters on line.There are 3 more posts in this series of posts.Please make sure you read them first.You can find the first post here. You can find the second post here. You can find the third post here.  In this new post we will build on the previous posts and we will demonstrate how to display the posters per category.We will add a ListView control on the PosterList.aspx and will bind data from the database. We will use the various templates.Then we will write code in the PosterList.aspx.cs to fetch data from the database.1) Launch Visual Studio and open your solution where your project lives2) Open the PosterList.aspx page. We will add some markup in this page. Have a look at the code below  <section class="posters-featured">                    <ul>                         <asp:ListView ID="posterList" runat="server"                            DataKeyNames="PosterID"                            GroupItemCount="3" ItemType="PostersOnLine.DAL.Poster" SelectMethod="GetPosters">                            <EmptyDataTemplate>                                      <table id="Table1" runat="server">                                            <tr>                                                  <td>We have no data.</td>                                            </tr>                                     </table>                              </EmptyDataTemplate>                              <EmptyItemTemplate>                                     <td id="Td1" runat="server" />                              </EmptyItemTemplate>                              <GroupTemplate>                                    <tr ID="itemPlaceholderContainer" runat="server">                                          <td ID="itemPlaceholder" runat="server"></td>                                    </tr>                              </GroupTemplate>                              <ItemTemplate>                                    <td id="Td2" runat="server">                                          <table>                                                <tr>                                                      <td>&nbsp;</td>                                                      <td>                                                <a href="PosterDetails.aspx?posterID=<%#:Item.PosterID%>">                                                    <img src="<%#:Item.PosterImgpath%>"                                                        width="100" height="75" border="1"/></a>                                             </td>                                            <td>                                                <a href="PosterDetails.aspx?posterID=<%#:Item.PosterID%>">                                                    <span class="PosterName">                                                        <%#:Item.PosterName%>                                                    </span>                                                </a>                                                            <br />                                                <span class="PosterPrice">                                                               <b>Price: </b><%#:String.Format("{0:c}", Item.PosterPrice)%>                                                </span>                                                <br />                                                        </td>                                                </tr>                                          </table>                                    </td>                              </ItemTemplate>                              <LayoutTemplate>                                    <table id="Table2" runat="server">                                          <tr id="Tr1" runat="server">                                                <td id="Td3" runat="server">                                                      <table ID="groupPlaceholderContainer" runat="server">                                                            <tr ID="groupPlaceholder" runat="server"></tr>                                                      </table>                                                </td>                                          </tr>                                          <tr id="Tr2" runat="server"><td id="Td4" runat="server"></td></tr>                                    </table>                              </LayoutTemplate>                        </asp:ListView>                    </ul>               </section>  3) We have a ListView control on the page called PosterList. I set the ItemType property to the Poster class and then the SelectMethod to the GetPosters method.  I will create this method later on.   (ItemType="PostersOnLine.DAL.Poster" SelectMethod="GetPosters")Then in the code below  I have the data-binding expression Item  available and the control becomes strongly typed.So when the user clicks on the link of the poster's category the relevant information will be displayed (photo,name and price)                                            <td>                                                <a href="PosterDetails.aspx?posterID=<%#:Item.PosterID%>">                                                    <img src="<%#:Item.PosterImgpath%>"                                                        width="100" height="75" border="1"/></a>                                             </td>4)  Now we need to write the simple method to populate the ListView control.It is called GetPosters method.The code follows   public IQueryable<Poster> GetPosters([QueryString("id")] int? PosterCatID)        {            PosterContext ctx = new PosterContext();            IQueryable<Poster> query = ctx.Posters;            if (PosterCatID.HasValue && PosterCatID > 0)            {                query = query.Where(p=>p.PosterCategoryID==PosterCatID);            }            return query;                    } This is a very simple method that returns information about posters related to the PosterCatID passed to it.I bind the value from the query string to the PosterCatID parameter at run time.This is all possible due to the QueryStringAttribute class that lives inside the System.Web.ModelBinding and gets the value of the query string variable id.5) I run my application and then click on the "Midfilders" link. Have a look at the picture below to see the results.  In the Site.css file I added some new CSS rules to make everything more presentable. .posters-featured {    width:840px;    background-color:#efefef;}.posters-featured   a:link, a:visited,    a:active, a:hover {        color: #000033;    }.posters-featured    a:hover {        background-color: #85c465;    }  6) I run the application again and this time I do not choose any category, I simply navigate to the PosterList.aspx page. I see all the posters since no query string was passed as a parameter.Have a look at the picture below   ?ake sure you place breakpoints in the code so you can see what is really going on.In the next post I will show you how to display poster details.Hope it helps!!!
