  • What do the participants say about the Open Day in South Africa?

    - by Maria Sandu
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 On the 26th of September, a group of students who were specifically selected to attend an Open day at Oracle South Africa, joined us at our offices in Woodmead, Johannesburg. The Conference room was filled with inquisitive minds. What we had in store for them was a detailed presentation about Oracle which was delivered by Zuko - Cluster Leader: Tech GB South Africa. The student’s many questions were all answered especially when we started addressing the opportunities we have and detailed information on our Graduate Programme. Our employees then came to talk about their experience. This allowed all the students to have an integrated learning experience. By inviting the students to walk around our Oracle Offices allowed them to see, talk, experience a bit of the culture and ask more questions. Here is some of the feedback from the attendees: Maxwell Moloi: “The open day truly served its purpose and exceeded expectations in the sense that I got to find out more about Oracle and all the different opportunities it has to offer. The fact that Oracle supplies a full solution to a customer and not just part of it and how the company manages to setup professional development for their employees is what entices me to want to join the rapidly growing team of Oracle.” Nqobile Mabaso: “I found the open day to be quite informative and enlightening because coming from a marketing background I could apply the knowledge I got from varsity to the Company I was able to point out what they do as part of their corporate social responsibility (Oracle recently partnered with the department of education to build a school), how Oracle emphasizes on relationship building because they know they sell to people and not companies and how they offer the full stack of solutions which gives them a competitive advantage over their competitors.” Nondumiso Mvelase: “The Open Day was a wonderful experience for me especially because I have never been part of an Open Day before, so it was absolutely amazing for me. It gave me a good idea of how it is to be part of Oracle. We were served with lovely breakfast and lunch which I enjoyed. I wish the Open Day went on for a whole week. Seeing and hearing from 2013 Graduates, telling us about their experience within Oracle was very inspiring to me. They were encouraging us to work hard if we ever got the opportunity they had. After hearing this from them I will definitely not take it for granted.” Itumeleng Moraka: “Before I walked into the Oracle offices all that was in my mind was databases and cloud storage. I was then surrounded by passionate, enthusiastic and welcoming employees. I came across a positive energy within the multinational company. I realized that Oracle is not a company that operates in survival mode. This may sound idealistic, but they operate in a non-traditional way investing more into innovation, they stay focused on what matters most about where technology is going and at the same time they are not losing sight of how their products make a difference in the world.” For more information on how to be part of the Oracle Graduate Programme please follow us on Facebook! https://www.facebook.com/CampusAtOracle /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-family:"Calibri","sans-serif"; mso-ascii- mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi- mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • Hybrid IT or Cloud Initiative – a Perfect Enterprise Architecture Maturation Opportunity

    - by Ted McLaughlan
    Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} All too often in the growth and maturation of Enterprise Architecture initiatives, the effort stalls or is delayed due to lack of “applied traction”. By this, I mean the EA activities - whether targeted towards compliance, risk mitigation or value opportunity propositions – may not be attached to measurable, active, visible projects that could advance and prove the value of EA. EA doesn’t work by itself, in a vacuum, without collaborative engagement and a means of proving usefulness. A critical vehicle to this proof is successful orchestration and use of assets and investment resources to meet a high-profile business objective – i.e. a successful project. More and more organizations are now exploring and considering some degree of IT outsourcing, buying and using external services and solutions to deliver their IT and business requirements – vs. building and operating in-house, in their own data centers. The rapid growth and success of “Cloud” services makes some decisions easier and some IT projects more successful, while dramatically lowering IT risks and enabling rapid growth. This is particularly true for “Software as a Service” (SaaS) applications, which essentially are complete web applications hosted and delivered over the Internet. Whether SaaS solutions – or any kind of cloud solution - are actually, ultimately the most cost-effective approach truly depends on the organization’s business and IT investment strategy. This leads us to Enterprise Architecture, the connectivity between business strategy and investment objectives, and the capabilities purchased or created to meet them. If an EA framework already exists, the approach to selecting a cloud-based solution and integrating it with internal IT systems (i.e. a “Hybrid IT” solution) is well-served by leveraging EA methods. If an EA framework doesn’t exist, or is simply not mature enough to address complex, integrated IT objectives – a hybrid IT/cloud initiative is the perfect project to advance and prove the value of EA. Why is this? For starters, the success of any complex IT integration project - spanning multiple systems, contracts and organizations, public and private – depends on active collaboration and coordination among the project stakeholders. For a hybrid IT initiative, inclusive of one or more cloud services providers, the IT services, business workflow and data governance challenges alone can be extremely complex, requiring many diverse layers of organizational expertise and authority. Establishing subject matter expertise, authorities and strategic guidance across all the disciplines involved in a hybrid-IT or hybrid-cloud system requires top-level, comprehensive experience and collaborative leadership. Tools and practices reflecting industry expertise and EA alignment can also be very helpful – such as Oracle’s “Cloud Candidate Selection Tool”. Using tools like this, and facilitating this critical collaboration by leading, organizing and coordinating the input and expertise into a shared, referenceable, reusable set of authority models and practices – this is where EA shines, and where Enterprise Architects can be most valuable. The “enterprise”, in this case, becomes something greater than the core organization – it includes internal systems, public cloud services, 3rd-party IT platforms and datacenters, distributed users and devices; a whole greater than the sum of its parts. Through facilitated project collaboration, leading to identification or creation of solid governance models and processes, a durable and useful Enterprise Architecture framework will usually emerge by itself, if not actually identified and managed as such. The transition from planning collaboration to actual coordination, where the program plan, schedule and resources become synchronized and aligned to other investments in the organization portfolio, is where EA methods and artifacts appear and become most useful. The actual scope and use of these artifacts, in the context of this project, can then set the stage for the most desirable, helpful and pragmatic form of the now-maturing EA framework and community of practice. Considering or starting a hybrid-IT or hybrid-cloud initiative? Running into some complex relationship challenges? This is the perfect time to take advantage of your new, growing or possibly latent Enterprise Architecture practice.

  • How You Helped Shape Java EE 7...

    - by reza_rahman
    I have been working with the JCP in various roles since EJB 3/Java EE 5 (much of it on my own time), eventually culminating in my decision to accept my current role at Oracle (despite it's inevitable set of unique challenges, a role I find by and large positive and fulfilling). During these years, it has always been clear to me that pretty much everyone in the JCP genuinely cares about openness, feedback and developer participation. Perhaps the most visible sign to date of this high regard for grassroots level input is a survey on Java EE 7 gathered a few months ago. The survey was designed to get open feedback on a number of critical issues central to the Java EE 7 umbrella specification including what APIs to include in the standard. When we started the survey, I don't think anyone was certain what the level of participation from developers would really be. I also think everyone was pleasantly surprised that a large number of developers (around 1100) took the time out to vote on these very important issues that could impact their own professional life. And it wasn't just a matter of the quantity of responses. I was particularly impressed with the quality of the comments made through the survey (some of which I'll try to do justice to below). With Java EE 7 under our belt and the horizons for Java EE 8 emerging, this is a good time to thank everyone that took the survey once again for their thoughts and let you know what the impact of your voice actually was. As an aside, you may be happy to know that we are working hard behind the scenes to try to put together a similar survey to help kick off the agenda for Java EE 8 (although this is by no means certain). I'll break things down by the questions asked in the survey, the responses and the resulting change in the specification. APIs to Add to Java EE 7 Full/Web Profile The first question in the survey asked which of four new candidate APIs (WebSocket, JSON-P, JBatch and JCache) should be added to the Java EE 7 Full and Web profile respectively. Developers by and large wanted all the new APIs added to the full platform. The comments expressed particularly strong support for WebSocket and JCache. Others expressed dissatisfaction over the lack of a JSON binding (as opposed to JSON processing) API. WebSocket, JSON-P and JBatch are now part of Java EE 7. In addition, the long-awaited Java EE Concurrency Utilities API was also included in the Full Profile. Unfortunately, JCache was not finalized in time for Java EE 7 and the decision was made not to hold up the Java EE release any longer. JCache continues to move forward strongly and will very likely be included in Java EE 8 (it will be available much sooner than Java EE 8 to boot). An emergent standard for JSON-B is also a strong possibility for Java EE 8. When it came to the Web Profile, developers were supportive of adding WebSocket and JSON-P, but not JBatch and JCache. Both WebSocket and JSON-P are now part of the Web Profile, now also including the already popular JAX-RS API. Enabling CDI by Default The second question asked whether CDI should be enabled in Java EE by default. The overwhelming majority of developers supported the default enablement of CDI. In addition, developers expressed a desire for better CDI/Java EE alignment (with regards to EJB and JSF in particular). Some developers expressed legitimate concerns over the performance implications of enabling CDI globally as well as the potential conflict with other JSR 330 implementations like Spring and Guice. CDI is enabled by default in Java EE 7. Respecting the legitimate concerns, CDI 1.1 was very careful to add additional controls around component scanning. While a lot of work was done in Java EE 6 and Java EE 7 around CDI alignment, further alignment is under serious consideration for Java EE 8. Consistent Usage of @Inject The third question was around using CDI/JSR 330 @Inject consistently vs. allowing JSRs to create their own injection annotations (e.g. @BatchContext). A majority of developers wanted consistent usage of @Inject. The comments again reflected a strong desire for CDI/Java EE alignment. A lot of emphasis in Java EE 7 was put into using @Inject consistently. For example, the JBatch specification is focused on using @Inject wherever possible. JAX-RS remains an exception with it's existing custom injection annotations. However, the JAX-RS specification leads understand the importance of eventual convergence, hopefully in Java EE 8. Expanding the Use of @Stereotype The fourth question was about expanding CDI @Stereotype to cover annotations across Java EE beyond just CDI. A solid majority of developers supported the idea of making @Stereotype more universal in Java EE. The comments maintained the general theme of strong support for CDI/Java EE alignment Unfortunately, there was not enough time and resources in Java EE 7 to implement this fairly pervasive feature. However, it remains a serious consideration for Java EE 8. Expanding Interceptor Use The final set of questions was about expanding interceptors further across Java EE. Developers strongly supported the concept. Along with injection, interceptors are now supported across all Java EE 7 components including Servlets, Filters, Listeners, JAX-WS endpoints, JAX-RS resources, WebSocket endpoints and so on. I hope you are encouraged by how your input to the survey helped shape Java EE 7 and continues to shape Java EE 8. Participating in these sorts of surveys is of course just one way of contributing to Java EE. Another great way to stay involved is the Adopt-A-JSR Program. A large number of developers are already participating through their local JUGs. You could of course become a Java EE JSR expert group member or observer. You should stay tuned to The Aquarium for the progress of Java EE 8 JSRs if that's something you want to look into...

  • State of the (Commerce) Union: What the healthcare.gov hiccups teach us about the commerce customer experience

    - by Katrina Gosek
    Guest Post by Brenna Johnson, Oracle Commerce Product A lot has been said about the healthcare.gov debacle in the last week. Regardless of your feelings about the Affordable Care Act, there’s a hidden issue in this story that most of the American people don’t understand: delivering a great commerce customer experience (CX) is hard. It shouldn’t be, but it is. The reality of the government’s issues getting the healthcare site up and running smooth is something we in the online commerce community know too well.  If there’s one thing the botched launch of the site has taught us, it’s that regardless of the size of your budget or the power of an executive with a high-profile project, some of the biggest initiatives with the most attention (and the most at stake) don’t go as planned. It may even give you a moment of solace – we have the same issues! But why?  Organizations engage too many separate vendors with different technologies, running sections or pieces of a site to get live. When things go wrong, it takes time to identify the problem – and who or what is at the center of it. Unfortunately, this is a brittle way of setting up a site, making it susceptible to breaks, bugs, and scaling issues. But, it’s the reality of running a site with legacy technology constraints in today’s demanding, customer-centric market. This approach also means there’s also a lot of cooks in lots of different kitchens. You’ve got development and IT, the business and the marketing team, an external Systems Integrator to bring it all together, a digital agency or consultant, QA, product experts, 3rd party suppliers, and the list goes on. To complicate things, different business units are held responsible for different pieces of the site and managing different technologies. And again – due to legacy organizational structure and processes, this is all accepted as the normal State of the Union. Digital commerce has been commonplace for 15 years. Yet, getting a site live, maintained and performing requires orchestrating a cast of thousands (or at least, dozens), big dollars, and some finger-crossing. But it shouldn’t. The great thing about the advent of mobile commerce and the continued maturity of online commerce is that it’s forced organizations to think from the outside, in. Consumers – whether they’re shopping for shoes or a new healthcare plan – don’t care about what technology issues or processes you have behind the scenes. They just want it to work.  They want their experience to be easy, fast, and tailored to them and their needs – whatever they are. This doesn’t sound like a tall order to the American consumer – especially since they interact with sites that do work smoothly.  But the reality is that it takes scores of people, teams, check-ins, late nights, testing, and some good luck to get sites to run, and even more so at Black Friday (or October 1st) traffic levels.  The last thing on a customer’s mind is making excuses for why they can’t buy a product – just get it to work. So what is the government doing? My guess is working day and night to get the site performing  - and having to throw big money at the problem. In the meantime they’re sending frustrated online users to the call center, or even a location where a trained “navigator” can help them in-person to complete their selection. Sounds a lot like multichannel commerce (where broken communication between siloed touchpoints will only frustrate the consumer more). One thing we’ve learned is that consumers spend their time and money with brands they know and trust. When sites are easy to use and adapt to their needs, they tend to spend more, come back, and even become long-time loyalists. Achieving this may require moving internal mountains, but there’s too much at stake to ignore the sea change in how organizations are thinking about their customer. If the thought of re-thinking your internal teams, technologies, and processes sounds like a headache, think about the pain associated with losing valuable customers – and dollars. Regardless if you’re in B2B or B2C, it’s guaranteed that your competitors are making CX a priority. Those early to the game who have made CX a priority have already begun to outpace their competition. So as you’re planning for 2014, look to the news this week. Make sure the customer experience is a focus at your organization. Expectations are at record highs. Map your customer’s journey, and think from the outside, in. How easy is it for your customers to do business with you? If they interact with many touchpoints across your organization, are the call center, website, mobile environment, or brick and mortar location in sync? Do you have the technology in place to achieve this? It’s time to give the people what they want!

  • The Raspberry Pi JavaFX In-Car System (Part 3)

    - by speakjava
    Ras Pi car pt3 Having established communication between a laptop and the ELM327 it's now time to bring in the Raspberry Pi. One of the nice things about the Raspberry Pi is the simplicity of it's power supply.  All we need is 5V at about 700mA, which in a car is as simple as using a USB cigarette lighter adapter (which is handily rated at 1A).  My car has two cigarette lighter sockets (despite being specified with the non-smoking package and therefore no actual cigarette lighter): one in the centre console and one in the rear load area.  This was convenient as my idea is to mount the Raspberry Pi in the back to minimise the disruption to the very clean design of the Audi interior. The first task was to get the Raspberry Pi to communicate using Wi-Fi with the ELM 327.  Initially I tried a cheap Wi-Fi dongle from Amazon, but I could not get this working with my home Wi-Fi network since it just would not handle the WPA security no matter what I did.  I upgraded to a Wi Pi from Farnell and this works very well. The ELM327 uses Ad-Hoc networking, which is point to point communication.  Rather than using a wireless router each connecting device has its own assigned IP address (which needs to be on the same subnet) and uses the same ESSID.  The settings of the ELM327 are fixed to an IP address of 192.168.0.10 and useing the ESSID, "Wifi327".  To configure Raspbian Linux to use these settings we need to modify the /etc/network/interfaces file.  After some searching of the web and a few false starts here's the settings I came up with: auto lo eth0 wlan0 iface lo inet loopback iface eth0 inet static     address 10.0.0.13     gateway 10.0.0.254     netmask 255.255.255.0 iface wlan0 inet static     address 192.168.0.1     netmask 255.255.255.0     wireless-essid Wifi327     wireless-mode ad-ho0 After rebooting, iwconfig wlan0 reported that the Wi-Fi settings were correct.  However, ifconfig showed no assigned IP address.  If I configured the IP address manually using ifconfig wlan0 192.168.0.1 netmask 255.255.255.0 then everything was fine and I was able to happily ping the IP address of the ELM327.  I tried numerous variations on the interfaces file, but nothing I did would get me an IP address on wlan0 when the machine booted.  Eventually I decided that this was a pointless thing to spend more time on and so I put a script in /etc/init.d and registered it with update-rc.d.  All the script does (currently) is execute the ifconfig line and now, having installed the telnet package I am able to telnet to the ELM327 via the Raspberry Pi.  Not nice, but it works. Here's a picture of the Raspberry Pi in the car for testing In the next part we'll look at running the Java code on the Raspberry Pi to collect data from the car systems.

  • MySQL Server 5.6 default my.cnf and my.ini

    - by user12626240
    We've introduced a default my.cnf / my.ini file for MySQL Server that you can now see in the 5.6.8 release candidate: # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M   # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin   # These are commonly set, remove the # and set as required. # basedir = ..... # datadir = ..... # port = ..... # socket = ..... # server_id = .....   # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M   sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES    There is also a template file called my-default.cnf or my-default.ini that has these lines near the start: # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL.   On Linux systems, the mysql_install_db command will copy the template file to the final location, where the server will read and use the file, removing the extra three lines. On Windows, the installer will create extra settings based on the answers you gave during installation. Neither will overwrite an existing my.cnf or my.ini file. The only initially active setting here is to change the value of  sql_mode from the server default of NO_ENGINE_SUBSTITUTION to NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES. This strict mode changes warnings for some non-standard behaviour into errors. This can cause applications which rely on the non-standard things, like dates that aren't valid, to lose data. If we had just changed the server default, the new setting would affect all servers that lack an explicit sql_mode setting, including those where strict mode is harmful. So we did it in the default file instead because that will only affect new server installations. You should expect that in our next version after 5.6, the server default will include STRICT_TRANS_TABLES. Our Windows installer and some of our connectors already use STRICT_TRANS_TABLES by default. Strict has been our preferred setting for many years and it is good to see some development platforms are using it. If you need the old behaviour, just remove the STRICT_TRANS_TABLES setting. If you do this, please also ask your application provider to make it unnecessary. They can do that by setting the session sql_mode setting in their own connections, so the rest of the applications using the server don't have to have an undesirable default. We've kept this file as small as possible because we found that our old files were too big and confused people. We've also now removed the old my-huge and related example files. One key part of this is the link to the documentation, where we will provide an introduction to some key settings. We'd like to hear your feedback on settings that will benefit most users or are most important to call out for existing users. Please do that by commenting here or if you prefer by adding comments to this bug report.

  • JVM process resident set size "equals" max heap size, not current heap size

Are my expectations wrong? What should I expect? I need the heap space to be able to grow during spikes (to avoid very slow Full GC), but I would like to have the resident set size as low as possible the rest of the time, to benefit the other processes running on the server.

  • Httpd problem, suspect an attack but not sure

    - by Bob
    On one of my servers when I type netstat -n I get a huge output, something like 400 entries for httpd. The bandwidth on the server isn't high, so I'm confused as to what's causing it. I'm suspecting an attack, but not sure. Intermittently, the web server will stop responding. When this happens all other services such as ping, ftp, work just normally. System load is also normal. The only thing that isn't normal I think is the "netstat -n" output. Can you guys take a look and see if there's something I can do? I have APF installed, but not sure what rules I should put into place to mitigate the problem. Btw, I'm running CentOS 5 Linux with Apache 2. root@linux [/backup/stuff/apf-9.7-1]# netstat -n|grep :80 tcp 0 0 120.136.23.56:80 220.181.94.220:48397 TIME_WAIT tcp 0 0 120.136.23.56:80

  • Squid 2.7.STABLE3-4.1 as a transparent proxy on Ubuntu Server 9.04

    - by E3 Group
    Can't get this to work at all! I'm trying to get this linux box to act as a transparent proxy and, with the help of DHCP, force everyone on the network to gate into the proxy. I have two ethernet connections, both to the same switch. And I'm trying to get 192.168.1.234 to become the default gateway. The actual WAN connection is to a gateway 192.168.1.1. eth0 is 192.168.1.234 eth1 is 192.168.1.2 Effectively I'm trying to make eth0 a LAN only interface and eth1 a WAN interface. I've oi should set the gateway for eth1 to point to 192.168.1.234 my squid.conf file has the following directives added at the bottom: nly set eth0 to have a gateway address in /etc/network/interfaces I'm not sure whether http_port 3128 transparent acl lan src 192.168.1.0/24 acl lh src 127.0.0.1/255.255.255.0 http_access allow lan http_access allow lh i've added the following routing commands: iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.1.2:3128 iptables -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128 I set a computer with TCP settings 192.168.1.234 as the gateway and opened up google.com, but it comes up with a request error.

  • How to make Firefox use TCP for DNS

    - by miniBill
    I want to use TCP for DNS, to bypass my ISP's slow and broken DNS servers. I'm not using (and don't want to use) a proxy. Note: I want to use DNS over TCP because if I use it over udp, no matter what server I set, I get answers from my ISP's DNS. Notice that I will fiercely downvote whoever suggests: programs to do TCP over DNS, the setting in about:config to make DNS go over the proxy too: I'm not using a proxy, use another DNS: I've already set up Google as my DNS, but I get intercepted. Example of what I mean by saying intercept: $ dig @8.8.8.8 thepiratebay.se ; <<>> DiG 9.8.1 <<>> @8.8.8.8 thepiratebay.se ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 24385 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;thepiratebay.se.

  • Allow anonymous upload for Vsftpd?

    - by user15318
    I need a basic FTP server on Linux (CentOS 5.5) without any security measure, since the server and the clients are located on a test LAN, not connected to the rest of the network, which itself uses non-routable IP's behind a NAT firewall with no incoming access to FTP. Some people recommend Vsftpd over PureFTPd or ProFTPd. No matter what I try, I can't get it to allow an anonymous user (ie. logging as "ftp" or "anonymous" and typing any string as password) to upload a file: # yum install vsftpd # mkdir /var/ftp/pub/upload # cat vsftpd.conf listen=YES anonymous_enable=YES local_enable=YES write_enable=YES xferlog_file=YES #anonymous users are restricted (chrooted) to anon_root #directory was created by root, hence owned by root.root anon_root=/var/ftp/pub/incoming anon_upload_enable=YES anon_mkdir_write_enable=YES #chroot_local_user=NO #chroot_list_enable=YES #chroot_list_file=/etc/vsftpd.chroot_list chown_uploads=YES When I log on from a client, here's what I get: 500 OOPS: cannot change directory:/var/ftp/pub/incoming I also tried "# chmod 777 /var/ftp/incoming/", but get the same error. Does someone know how to configure Vsftpd with minimum security? Thank you. Edit: SELinux is disabled and here are the file permissions: # cat /etc/sysconfig/selinux SELINUX=disabled SELINUXTYPE=targeted SETLOCALDEFS=0 # sestatus SELinux status: disabled # getenforce Disabled # grep ftp /etc/passwd ftp:x:14:50:FTP User:/var/ftp:/sbin/nologin # ll /var/ drwxr-xr-x 4 root root 4096 Mar 14 10:53 ftp # ll /var/ftp/ drwxrwxrwx 2 ftp ftp 4096 Mar 14 10:53 incoming drwxr-xr-x 3 ftp ftp 4096 Mar 14 11:29 pub Edit: latest vsftpd.conf: listen=YES local_enable=YES write_enable=YES xferlog_file=YES #anonymous users are restricted (chrooted) to anon_root anonymous_enable=YES anon_root=/var/ftp/pub/incoming anon_upload_enable=YES anon_mkdir_write_enable=YES #500 OOPS: bad bool value in config file for: chown_uploads chown_uploads=YES chown_username=ftp Edit: with trailing space removed from "chown_uploads", err 500 is solved, but anonymous still doesn't work: client> ./ftp server Connected to server. 220 (vsFTPd 2.0.5) Name (server:root): ftp 331 Please specify the password.

I don't find any FTP log file in /var/log to investigate. Edit: Here's a working configuration to let ftp/anonymous connect and upload files to /var/ftp: listen=YES anonymous_enable=YES write_enable=YES anon_upload_enable=YES anon_mkdir_write_enable=YES

  • script to recursively check for and select dependencies

    - by rp.sullivan
    I have written a script that does this but it is one of my first scripts ever so i am sure there is a better way:) Let me know how you would go about doing this. I'm looking for a simple yet efficient way to do this. Here is some important background info: ( It might be a little confusing but hopefully by the end it will make sense. ) 1) This image shows the structure/location of the relevant dirs and files. 2) The packages.file located at ./config/default/config/packages is a space delimited file. field5 is the "package name" which i will call $a for explanations sake. field4 is the name of the dir containing the $a.dir i will call $b field1 shows if the package is selected or not, "X"(capital x) for selected and "O"(capital o as in orange) for not selected. Here is an example of what the packages.file might contain: ... X ---3------ 104.800 database gdbm 1.8.3 / base/library CROSS 0 O -1---5---- 105.000 base libiconv 1.13.1 / base/tool CROSS 0 X 01---5---- 105.000 base pkgconfig 0.25 / base/tool CROSS 0 X -1-3------ 105.000 base texinfo 4.13a / base/tool CROSS DIETLIBC 0 O -----5---- 105.000 develop duma 2_5_15 / base/development CROSS NOPARALLEL 0 O -----5---- 105.000 develop electricfence 2_4_13 / base/development CROSS 0 O -----5---- 105.000 develop gnupth 2.0.7 / extra/development CROSS NOPARALLEL FPIC-QUIRK 0 ... 3) For almost every package listed in the "packages.file" there is a corresponding ".cache file" The .cache file for package $a would be located at ./package/$b/$a/$a.cache The .cache files contain a list of dependencies for that particular package. Here is an example of one of the .cache files might look like. Note that the dependencies are field2 of lines containing "[DEP]" These dependencies are all names of packages in the "package.file" [TIMESTAMP] 1134178701 Sat Dec 10 02:38:21 2005 [BUILDTIME] 295 (9) [SIZE] 11.64 MB, 191 files [DEP] 00-dirtree [DEP] bash [DEP] binutils [DEP] bzip2 [DEP] cf [DEP] coreutils ... So with all that in mind... I'm looking for a shell script that: From within the "main dir" Looks at the ./config/default/config/packages file and finds the "selected" packages and reads the corresponding .cache Then compiles a list of dependencies that excludes the already selected packages Then selects the dependencies (by changing field1 to X) in the ./config/default/config/packages file and repeats until all the dependencies are met Note: The script will ultimately end up in the "scripts dir" and be called from the "main dir". If this is not clear let me know what need clarification. For those interested I'm playing around with T2 SDE. If you are into playing around with linux it might be worth taking a look.

  • xterm not wrapping text properly

    - by mulllhausen
    I'm configuring both my gnome-terminal and xterm columns (i still haven't picked which of these I will be using) and I have a couple of issues I would like to fix: the typing area seems to be smaller (fewer columns) than the display area the typed text is not wrapping to the next line when it reaches the end - it just continues back around on the same line, overwriting the prompt (i have set a custom bash prompt with PS1 in case this is relevant) $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 7.1 (wheezy) Release: 7.1 Codename: wheezy $ echo $TERM xterm $ stty -a [peter@pc ~] $ stty -a speed 38400 baud; rows 52; columns 126; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = M-^?; eol2 = M-^?; swtch = M-^?; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0; -parenb -parodd cs8 hupcl -cstopb cread -clocal -crtscts -ignbrk brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon -ixoff -iuclc ixany imaxbel iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke $[peter@mine ~] $ # the column width only goes up to here ------------------------------------------------> the results are identical in both the xterm and in gnome-terminal 3.4.1.1 and as you can see, the output of the stty -a command goes right up to the edge of the screen, while the typing does not go that far. I have found that I can get the desired result by setting the columns to a very large number, eg: $ stty cols 1800 this fixes both problems. Is it the right way to go about solving this problem? Will this "break" any of the output from programs? So far I have tried top and stty -a and these seem OK. more info as requested in the comments i found that if i cat some input into a file then the columns actually strech the full width of the terminal window: [peter@mine applications] $ cat > /tmp/asd aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaasssssssssssssssssssssssssssssssssssssssssssssssssssssssssssqqqqqqqqqqqqqqqq qqqq does this imply that it is actually bash that is restricting the number of columns and not the terminal? if so then how to alter the number of columns in bash?

  • Effect of HOME on libreoffice to convert to pdf as non-root user

    - by user1032531
    I installed libreoffice-headless and can convert documents when logged on as root. I then tried doing so as another user, and it didn't show an error, but didn't convert the file. I then found that if I get rid of the HOME=/tmp/ayb, it works with the other user. Doesn't HOME=/tmp/ayb just allow files to default to this directory if not specified? (Sorry, I tried to search "Linux HOME", but as you probably expect, received a bunch of non-relevant results). If not, what is the purpose of specifying HOME? Why does setting HOME prevent it from converting on non-root users? Note that /tmp and /tmp/ayb or both 0777.

  • LUKS with LVM, mount is not persistent after reboot

    I have created a Logical vol and used luks to encrypt it. But while rebooting the server. I get a error message (below), therefore I would have to enter the root pass and disable the /etc/fstab entry. So mount of the LUKS partition is not persistent during reboot using LUKS.

  • Access denied to mysql cause by invalid server hostname bind address

    - by Mark
    I cannot login to mysql using the terminal. [root@fst mysql]# mysql -h localhost -u admin -p Enter password: ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES) I am sure I have the correct password. The mysql is also running when I check status. The mysql database is also present in the directory /var/lib/mysql/. The host host.myi, host.myd and host.frm are present. By the way this a related to question on my previous problem MySQL server quit without updating PID file . Initially the problem arise when the root directory was full. To be able to login to directadmin and start mysql, I added a soft link of the /var/lib/mysql/ to /home/mysql. Since my database used up the most of the root directory. The root directory has 50Gb and /home has 1.5Gb. Somehow the /var/lib/mysql/idbdata1 is corrupted. So I move it to another location. Now, I can start the mysql server but I cannot login into it. Below are the contents from the myql logs. 121212 20:44:10 mysqld_safe mysqld from pid file /var/lib/mysql/fst.srv.net.pid ended 121212 20:44:10 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 121212 20:44:10 [Note] Plugin 'FEDERATED' is disabled. 121212 20:44:10 InnoDB: The InnoDB memory heap is disabled 121212 20:44:10 InnoDB: Mutexes and rw_locks use GCC atomic builtins 121212 20:44:10 InnoDB: Compressed tables use zlib 1.2.3 121212 20:44:10 InnoDB: Using Linux native AIO 121212 20:44:10 InnoDB: Initializing buffer pool, size = 128.0M 121212 20:44:10 InnoDB: Completed initialization of buffer pool 121212 20:44:10 InnoDB: highest supported file format is Barracuda. 121212 20:44:11 InnoDB: Waiting for the background threads to start 121212 20:44:12 InnoDB: 1.1.8 started; log sequence number 1595675 121212 20:44:12 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306 121212 20:44:12 [Note] - '0.0.0.0' resolves to '0.0.0.0'; 121212 20:44:12 [Note] Server socket created on IP: '0.0.0.0'. 121212 20:44:12 [Note] Event Scheduler: Loaded 0 events 121212 20:44:12 [Note] /usr/sbin/mysqld: ready for connections.

  • Forward all traffic through an ssh tunnel

    - by Eamorr
    I hope someone can follow this and I'll explain as best I can. I'm trying to forward all traffic from port 6999 on x.x.x.224, through an ssh tunnel, and onto port 7000 on x.x.x.218. Here is some ASCII art: |browser|-----|Squid on x.x.x.224|------|ssh tunnel|------<satellite link>-----|Squid on x.x.x.218|-----|www| 3128 6999 7000 80 When I remove the ssh tunnel, everything works fine. The idea is to turn off encryption on the ssh tunnel (to save bandwidth) and turn on maximum compression (to save more bandwidth). This is because it's a satellite link. Here's the ssh tunnel I've been using: ssh -C -f -C -o CompressionLevel=9 -o Cipher=none [email protected] -L 7000:172.16.1.224:6999 -N The trouble is, I don't know how to get data from Squid on x.x.x.224 into the ssh tunnel? Am I going about this the wrong way? Should I create an ssh tunnel on x.x.x.218? I use iptables to stop squid on x.x.x.224 from reading port 80, but to feed from port 6999 instead (i.e. via the ssh tunnel). Do I need another iptables rule? Any comments greatly appreciated. Many thanks in advance, Regarding Eduardo Ivanec's question, here is a netstat -i any port 7000 -nn dump from x.x.x.218: 14:42:15.386462 IP 172.16.1.224.40006 > 172.16.1.218.7000: Flags [S], seq 2804513708, win 14600, options [mss 1460,sackOK,TS val 86702647 ecr 0,nop,wscale 4], length 0 14:42:15.386690 IP 172.16.1.218.7000 > 172.16.1.224.40006: Flags [R.], seq 0, ack 2804513709, win 0, length 0 Update 2: When I run the second command, I get the following error in my browser: ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://109.123.109.205/index.php Zero Sized Reply Squid did not receive any data for this request.

  • Quantifying the effects of partition mis-alignment

    - by Matt
    I'm experiencing some significant performance issues on an NFS server. I've been reading up a bit on partition alignment, and I think I have my partitions mis-aligned. I can't find anything that tells me how to actually quantify the effects of mis-aligned partitions. Some of the general information I found suggests the performance penalty can be quite high (upwards of 60%) and others say it's negligible. What I want to do is determine if partition alignment is a factor in this server's performance problems or not; and if so, to what degree? So I'll put my info out here, and hopefully the community can confirm if my partitions are indeed mis-aligned, and if so, help me put a number to what the performance cost is. Server is a Dell R510 with dual E5620 CPUs and 8 GB RAM. There are eight 15k 2.5” 600 GB drives (Seagate ST3600057SS) configured in hardware RAID-6 with a single hot spare. RAID controller is a Dell PERC H700 w/512MB cache (Linux sees this as a LSI MegaSAS 9260). OS is CentOS 5.6, home directory partition is ext3, with options “rw,data=journal,usrquota”. I have the HW RAID configured to present two virtual disks to the OS: /dev/sda for the OS (boot, root and swap partitions), and /dev/sdb for a big NFS share: [root@lnxutil1 ~]# parted -s /dev/sda unit s print Model: DELL PERC H700 (scsi) Disk /dev/sda: 134217599s Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 63s 465884s 465822s primary ext2 boot 2 465885s 134207009s 133741125s primary lvm [root@lnxutil1 ~]# parted -s /dev/sdb unit s print Model: DELL PERC H700 (scsi) Disk /dev/sdb: 5720768639s Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 34s 5720768606s 5720768573s lvm Edit 1 Using the cfq IO scheduler (default for CentOS 5.6): # cat /sys/block/sd{a,b}/queue/scheduler noop anticipatory deadline [cfq] noop anticipatory deadline [cfq] Chunk size is the same as strip size, right?

  • Archlinux/atheros WLAN configuration troubles

    - by GrinReaper
    I'm trying to config archlinux to use my wireless network adapter. It's quite troublesome. From what I've gathered, it's an atheros network adapter, using the ath5k driver/module... I can't get it to work; any ideas? Here's some of the output from my tinkering: # lspci | grep -i net 00:0a.0 Ethernet controller: nVidia corporation MCP67 Ethernet (reva2) 03:00.0 Ethernet controller: atheros communications inc.

Sorry, first time using a linux distro... EDIT: So I just tried this: I actually just did this twice. (I can't tell which setting is on/off for my wireless adapter. The lights are blue all the time now.) #rfkill list 0: hp-wifi: wireless lan softblocked: no hardblocked :yes 1: hp-bluetooth: bluetooth softblocked: no hardblocked :yes 3: phy1: wireless lan softblocked: no hardblocked :yes #rfkill list 0: hp-wifi: wireless lan softblocked: no hardblocked :no 1: hp-bluetooth: bluetooth softblocked: no hardblocked no 3: phy1: wireless lan softblocked: no hardblocked :yes 7: hci0: bluetooh 0: hp-wifi: wireless lan softblocked: no hardblocked :no I've dug around some other articles and it seems like ath5k is supposed to be preferable to madwifi, so should i be using madwifi? I'm 99% sure I disabled the hardblock (by turning it ON) but, as shown above, phy1 wireless lan is STILL hardblocked. What gives? Maybe I've made some more fundamental error in a basic config file? EDIT: I've fixed the hardblock. I've tried pinging www.google.com, but to no avail. I get: ping: unknown host www.google.com In the arch wiki: Edit /etc/hosts and add the same HOSTNAME you entered in /etc/rc.conf: 127.0.0.1 archlinux.domain.org localhost.localdomain localhost archlinux To my understanding, hostname is just a user-specified and based on preference(?) My /etc/rc.conf: HOSTNAME="gestalt" My /etc/hosts: 127.0.0.1 localhost.localdomain localhost gestalt but should it be the following? 120.0.0.1 localhost.domain.org localhost.localdomain localhost gestalt

Can anyone shed any light on why the dependencies might not be resolved correctly? ldd /usr/sbin/httpd libm.so.6 => /lib64/libm.so.6 (0x00002b02370db000) libpcre.so.0 => /lib64/libpcre.so.0 (0x00002b023735e000) libselinux.so.1 => /lib64/libselinux.so.1 (0x00002b023757a000) libaprutil-1.so.0 => not found libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00002b0237793000) libldap-2.3.so.0 => /usr/lib64/libldap-2.3.so.0 (0x00002b02379cb000) liblber-2.3.so.0 => /usr/lib64/liblber-2.3.so.0 (0x00002b0237c06000) libdb-4.3.so => /lib64/libdb-4.3.so (0x00002b0237e14000) libexpat.so.0 => /lib64/libexpat.so.0 (0x00002b0238109000) libapr-1.so.0 => not found libpthread.so.0 => /lib64/libpthread.so.0 (0x00002b023832c000) libdl.so.2 => /lib64/libdl.so.2 (0x00002b0238547000) libc.so.6 => /lib64/libc.so.6 (0x00002b023874c000) libsepol.so.1 => /lib64/libsepol.so.1 (0x00002b0238aa3000) /lib64/ld-linux-x86-64.so.2 (0x00002b0236ebe000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00002b0238ce9000) libsasl2.so.2 => /usr/lib64/libsasl2.so.2 (0x00002b0238eff000) libssl.so.6 => /lib64/libssl.so.6 (0x00002b0239118000) libcrypto.so.6 => /lib64/libcrypto.so.6 (0x00002b0239364000) libgssapi_krb5.so.2 => /usr/lib64/libgssapi_krb5.so.2 (0x00002b02396b6000) libkrb5.so.3 => /usr/lib64/libkrb5.so.3 (0x00002b02398e4000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x00002b0239b79000) libk5crypto.so.3 => /usr/lib64/libk5crypto.so.3 (0x00002b0239d7c000) libz.so.1 => /usr/lib64/libz.so.1 (0x00002b0239fa1000) libkrb5support.so.0 => /usr/lib64/libkrb5support.so.0 (0x00002b023a1b5000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x00002b023a3be000) yet this is the i386 package apr-util-1.2.7-11.el5.i386 : Apache Portable Runtime Utility library Repo : installed Matched from: Filename : /usr/lib/libaprutil-1.so.0
