  • WPA2 authentication fails using USB network devices (Linksys and Rosewill)

    - by Greg Youtz
    Decided to reduce the clutter in the house and replace a wired connection with a wireless one on my wife's system using USB network device Rosewill RNX-X1. I can see and connect to unprotected network, but WPA2 authentication repeatedly fails. Tried the same with a Linksys USB network adapter. Both failed to authenticate. Worth noting that I recently switched from Comcast to CenturyLink and so switched routers. The system connected successfully to previous router (Linksys EA4500) using WPA2. Would think it is the router (Actiontec C1000A) but all other devices (TV, iPad, Windows, Blackberry, and Squeezebox) connect ok. Would appreciate some diagnostic guidance and insight (phrased for a newbie!)

  • Can't connect to Wired Network after installing 12.04

    - by ezz9
    I have installed 12.04 into a used HP Compaq DC 7100 CMT. Plugged in LAN cable into the computer and it says network disconnected. from what I understand on the things I've read, it's not getting the address right, maybe it's just a guess (hardware address 00:16:35:78:47:bb). I know the LAN cable is working I can get on the net with the old computer. (Old computer is using device MAC address; Auto eth0 00:11:11:E6:4F:FE). I have put this address into the newer HP and it shows last used (minutes ago) but no Internet sever not found. I tried the hardware address it says never. I feel and think this should be easy to fix. But I just don't know. Here is the info everyone has asked for, but they never say what I should do. sudo lshw -C network; rfkill list; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; uname -a; ifconfig; route -n *-network description: ethernet interface product; NetXtreme BCM5751 Gigabit Ethernet PCI Express vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:40:00.0 logical name: eth0 verson: 01 serial: 00:16:35:78:47:bb size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000-fd configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion= 3.121 duplex=full firmware=5751-v3.29a latency=0 link=yes multicast=yes port=twi sted pair speed=100Mbit/s resources: irq:17 memory:f0400000-f040ffff auto lo iface lo inet loopback DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION= "Ubuntu 12.04 LTS" 00:00.0 host bridge [0600]: Inter Corporation 82915G/P/GV/GL/PL/910GL Memory Con troller Hub [8086:2580] (rev 04) 00.02.0 VGA compatible controller [0300]: Intel Corporation 82915G/GV/910GL inte grated Graphics Controller [8086:2582] (rev 04) 00:1c.0 PCI bridge [0604]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 1 [8086:2660] (rev 03) 00:1c.1 PCI bridge [0604]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 2 [8086:2662] (rev 03) 00:1d.0 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB UHCI #1 [8086:2658] (rev 03) 00:1d.1 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB UHCI #2 [8086:2659] (rev 03) 00:1d.2 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB UHCI #3 [8086:265a] (rev 03) 00:1d.3 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB UHCI #4 [8086:265b] (rev 03) 00:1d.7 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB2 UHCI Controller [8086:265c] (rev 03) 00:1e.0 PCI bridge [0604]: Intel Corporation 82801 PCI bridge [8086:244e] (rev d 3) 00:1e.2 Multimedia audio controller [0401]: Intel Corporation 82801FB/FBM/FR/FW/ FRW (ICH6 Family) AC'97 Autio conrtroller [8086:266e] (rev 03) 00:1f.0 ISA bridge [0601]: Intel Corporation 82801FB/RF (ICH6/ICH6R) LPC Interfa ce Bridge [8086:2640] (rev 03) 00:1f.1 IDE interface [0101]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 fami ly) IDE Controller [8086:266f] (rev 03) 00:1f.2 IDE interface [0101]: Intel Corporation 82801FB/FW (ICH6/ICH6W) SATA Con troller [8086:2651] (rev 03) 40:00.0 Ethernet controller [0200]: Broadcom Corporation NetXreme BCM5751 Gigab it Ethernet PCI Express [14e4:1677} (rev 01) Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Linux bob-desktop 3.2.0-23-generic-pae #36-Ubuntu SMP Tpr 10 22:19:09 UTC 20 12 i686 i686 i386 GNU/Linux eth0 Link encap:Ethernet HWaddr 00:16:35:78:47:bb inet6 addr: fe80::216:35ff:47bb/64 Scope:link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2517 errors:0 dropped:0 overruns:0 frame:0 TX packets:164 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:164508 (164.5 KB) TX bytes: 40884 (40.0 KB) Interrupt:17 lo Link encap:Local loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3290 errors:0 dropped:0 overruns:0 frame:0 TX packets:3290 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen: 0 RX bytes:267212 (267.2 KB) TX bytes: 267212 (267.2 KB) Kernel Ip routing table Destination Gateway Genmask Flags Metric Ref Use Iface ran this sudo dhclient eth0 no reply ran this ip addr 1: lo <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST ,MULTICAST ,UP ,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/enter 00:16:35:78:47:BB brd ff:ff:ff:ff:ff:ff inet 169.254.7.172/16 brd 169.254.255.255 scope link eth0:avahi inet6 fe80::216:35ff:fe78:47bb/64 scope link valid_lft forever preferred_lft forever Help please.

  • Is windows a "second class citizen" in the django community?

    - by Daniel Upton
    I'm currently doing R&D for a web application which we plan to host ourselves initially and then allow customers to self host. My task has been evaluating web frameworks to see which would give us the biggest productivity initially and ease of maintence while also allowing us to easily support deployment to customer controlled environments. Our team has experience with ASP.NET (MVC and Webforms) and Ruby on Rails. Our experience with rails is that windows deployment is a very taboo subject and any questions on IRC or SO are met with knee jerk "why not linux" responses.. However in this case our target market may be running windows or linux servers. Is this also the case in django land? Is it possible with rubbish performance? Is it possible with lost of pain? Is it seen as reasonable and not treated as a completely stupid idea for not wanting to run linux?

  • Juju didn't configure rabbitmq for openstack?

    - by SaM
    I have installed ubuntu Openstack HA with juju with all 24 servers. But my openstack is not working at all. On dashboard on every page I get errors saying "could not retrieve usage information", "could not retrieve volume information, "could not retrieve .....etc I spent hours and have discovered that juju has not done configuration correctly. I found that on cloud controller in nova.conf juju has added rabitmq vhost enrty, but that virtual host is not added in rabbitmq. Then how is its suppose to work? And on juju-gui canvas rabbimq is all green and is working fine, which in reality its not. I am really wondering if juju has really done correct configuration in all 24 servers now, I am getting the feeling that it would have been faster if I would have done openstack deployment manually instead of using juju. Why was the virtual host entry not added in rabbitmq? How should I solve this?

  • GPL vs plugin interfaces not designed with a specific application in mind

    - by Kristóf Marussy
    I am not seeking or in need of legal advice, but an interesting though experiment came to my mind. Imagine the following situtation (I cannot really think about a concrete example and I am unsure if a real manifestation even exists): there is a free (libre) api A licensed under some permissive license or even LGPL. Non-free application B implements this api in order host plugins, but there are other free software doing the same thing. Moreover, there is plugin C acting as a plugin under api A. It links to library D, that is under GPL, so C is also under GPL. Plugins using A are loaded into hosts via a dlopen-like mechanism and use complex data structure for host-plugin communication. Neither B nor C distribute any files that may be required for A to function properly (like headers containing the structure definitions of A or dynamic libraries containing helper functions for A written by the authors of A), but such things may exist. Now some user installs application B and plugin C on his machine, along with anything that may be required for api A to function properly. Then he proceeds and loads C into B and creates some intellectual property with B which is not a piece of software. Did a GPL violation happend at some point, and if so, who violated GPL and why? The authors of C violate D's license by making C possible to be used in non-free host B? This is a possibility because they can't give and exception of GPL (like one described in http://www.gnu.org/licenses/gpl-faq.html#GPLPluginsInNF or http://www.gnu.org/licenses/gpl-faq.html#LinkingOverControlledInterface) due to D's license terms. The authors of B violate C's and D's license by making C possible to be loaded in B? This is a possibility because http://www.gnu.org/licenses/gpl-faq.html#NFUseGPLPlugins disallows the mechanisms A uses for communitation between the free and non-free modules. The authors of A, because the api may be used (and in this case, was used) for communication between GPL'd and non-free software. This would be extremely absurd. The user, because at the moment of loading B into C, he made a derived work of C. I think this is impossible, because he does not distribute it. But would the situation change is he decided to release a configuration file of B which makes B load C as a plugin? Nobody, because A counts as a 'system library', and both B and C directly interact only with A, not eachother. In a sane world, this would happen... A concrete example of A could be some kind of audio (think LADSPA) or image processing api. However, I could find no such interface (that is free software, generic and is also implemented by commercial tools). A real-world example could also be quite enlightening.

  • XNA: Networking gone totally out of sync

    - by MesserChups
    I'm creating a multiplayer interface for a game in 2D some of my friends made, and I'm stuck with a huge latency or sync problem. I started by adapting my game to the msdn xna network tutorial and right now when I join a SystemLink network session (1 host on PC and 1 client on Xbox) I can move two players, everything is ok, but few minutes later the two machines start being totally out of synchronization. When I move one player it takes 10 or 20 seconds (increasing with TIME) to take effect on the second machine. I've tried to : Create a thread which calls NetworkSession.Update() continuously as suggested on this forum, didn't worked. Call the Send() method one frame on 10, and the receive() method at each frame, didn't worked either. I've cleaned my code, flushed all buffers at each call and switched the host and client but the problem still remain... I hope you have a solution because I'm running out of ideas... Thanks SendPackets() code : protected override void SendPackets() { if ((NetworkSessionState)m_networkSession.SessionState == NetworkSessionState.Playing) //Only while playing { //Write in the packet manager m_packetWriter.Write(m_packetManager.PacketToSend.ToArray(), 0, (int)m_packetManager.PacketToSend.Position); m_packetManager.ResetPacket(); //flush //Sends the packets to all remote gamers foreach (NetworkGamer l_netGamer in m_networkSession.RemoteGamers) { if (m_packetWriter.Length != 0) { FirstLocalNetGamer.SendData(m_packetWriter, SendDataOptions.None, l_netGamer); } } m_packetWriter.Flush();//m m_packetWriter.Seek(0, 0); } } ReceivePackets() code : public override void ReceivePackets() { base.ReceivePackets(); if ((NetworkSessionState)m_networkSession.SessionState == NetworkSessionState.Playing) //Only while playing { if (m_networkSession.LocalGamers.Count > 0) //Verify that there's at least one local gamer { foreach (LocalNetworkGamer l_localGamer in m_networkSession.LocalGamers) { //every LocalNetworkGamer must read to flush their stream // Keep reading while packets are available. NetworkGamer l_oldSender = null; while (l_localGamer.IsDataAvailable) { // Read a single packet, even if we are the host, we must read to clear the queue NetworkGamer l_newSender; l_localGamer.ReceiveData(m_packetReader, out l_newSender); if (l_newSender != l_oldSender) { if ((!l_newSender.IsLocal) && (l_localGamer == FirstLocalNetGamer)) { //Parsing PacketReader to MemoryStream m_packetManager.Receive(new MemoryStream(m_packetReader.ReadBytes(m_packetReader.Length))); } } l_oldSender = l_newSender; m_packetReader.BaseStream.Flush(); m_packetReader.BaseStream.Seek(0, SeekOrigin.Begin); } } m_packetManager.ParsePackets(); } } }

  • Using multiple A-records for my domain - do web browsers ever try more than one?

    - by Jonas
    If I add multiple A-records for my domain, they are returned in a round robin order by DNS-servers. E.g: 1.1.1.1 A example.com 1.1.1.2 A example.com 1.1.1.3 A example.com But how does webbrowsers react if the first host (1.1.1.1) is down (unreachable)? do they try the second host (1.1.1.2) or do they return a error message to the user? Are there any difference between the most popular browsers? If I implement my own application, I can implement so that the second is used in case the first is down, so it's possible. And this would be very helpful to create a fault tolerant website.

  • How to configure apache / php / postfix website emails when using vhosts?

    - by Alistair Buxton
    I have a LAMP webserver configured to serve multiple websites. Each virtual host has various PHP applications, mainly Wordpress. When users sign up to the Wordpress sites, email is sent by PHP through to postfix, and then on to the receiver. The problem is that postfix is identifying itself to the remote server with the contents of /etc/hostname, which is not a fully qualified domain name. Some mail servers reject this and the mail bounces. Additionally, the return path is being set to one of the vitual host domains, seemingly at random. I could set /etc/hostname to one of the website domain names, but then the emails from the other websites would have a wrong server in the headers, and this would not fix the return-path issue. Possibly related, apache2 says "could not determine the server's fully qualified domain name" on startup. How do I fix this so that each website can send email without revealing the other websites hosted on the server?

  • Are libc versions tied to kernel versions?

    - by mathematician1975
    After reading the answers to my previous question I have come to the conclusion that an answer to the following question is what I was actually looking for: Does a particular version of the kernel require a particular version of libc to run properly? Basically my problem stems from building an application on my 12.04 ubuntu and trying to run it on 8.04. I have since learned from this and other stackexchange forums that it is backward compatibility of libc that causes these problems. Therefore what I am perhaps naively trying to do is build the same version of libc that exists on my target and then link against that on my host when I build the application. Then in an ideal world when I copy this to the host, having been linked to the "correct" libc it should work (in my head at least). I have been totally unable to find a way to install an older libc on my system, and wondered if each version is tightly bound to a kernel version, hence the above question.

I bought site.com on company that is using their own nameservers - ns.a.com. And linked website to their own servers. I bought hosting on another company that is using nameservers - ns.b.com. Should I just change ns.a.com on my DOMAIN to ns.b.com? Or should I link all DNS entries on my domain control panel to host ip addresses?

  • How to make Jetty webserver listen on port 80?

    - by Jonas
    I would like to use Jetty as a webserver. I have edited the configuration file at /etc/default/jetty and set: # change to 0 to allow Jetty start NO_START=0 # Listen to connections from this network host # Use 0.0.0.0 as host to accept all connections. JETTY_HOST=0.0.0.0 Now I can reach the Jetty webserver at http://192.168.1.10:8080 but I would like to have Jetty listening on port 80. I have tried this setting in the same configuration file: # The network port used by Jetty JETTY_PORT=80 and then restart Jetty with sudo service jetty restart but it doesn't work. How can I change so that the Jetty webserver is listening on port 80?

  • SSH as root using public key still prompts for password on RHEL 6.1

    - by Dean Schulze
    I've generated rsa keys with cygwin ssh-keygen and copied them to the server with ssh-copy-id -i id_rsa.pub [email protected] I've got the following settings in my /etc/ssh/sshd_config file RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys PermitRootLogin yes When I ssh [email protected] it still prompts for a password. The output below from /usr/sbin/sshd -d says that a matching keys was found in the .ssh/authorized_keys file, but it still requires a password from the client. I've read a bunch of web postings about permissions on files and directories, but nothing works. Is it possible to ssh with keys in RHEL 6.1 or is this forbidden?

  • Free or Low Cost Web Hosting for Small Website [duplicate]

    - by etangins
    This question already has an answer here: How to find web hosting that meets my requirements? 5 answers I have a small website (between 2000 and 10000) page-views a day. I'm looking for a free or low cost web host. I tried 50webs.com but their server breaks down. So as not to cause debate, I am also just looking for links to good information sources for web hosting if just finding a good web host is too general. I currently only use HTML, CSS, and JavaScript though I'm considering learning PhP and other more advanced languages to step up my game.

  • How do I turn on wireless adapter on HP Envy dv6 7200 under Ubuntu (any version)?

    - by Dave B.
    I have a new HP Envy dv6 7200 with dual boot Windows 8 / Ubuntu 12.04. In windows, the F12 key in Windows activates the "airplane mode" switch which enables/disables both on-board (mini PCIe) and USB wireless adapters. In Ubuntu, however, the wireless adapter is turned off by default and cannot be turned back on via the F12 key (or any other combination of F12 and Ctrl, Fn, Shift, etc.). Let me explain the "fixes" I've seen in various forums and explain what did or did not happen. These are listed in no particular order. (Spoiler alert: wireless is still broke). Solution 1? Use HP's "Wireless Assistant" utility to permanently activate the wireless card in Windows, then boot into Ubuntu to happily find it working. Unfortunately, this utility works in Windows 7 but not Windows 8. On the other hand, hardware drivers from HP are only available for Windows 8 for this model. Catch 22 (I could not find a comparable utility for Windows 8). Solution 2? Use a USB wireless adapter to sidestep the on-board device. I purchased such a device from thinkpenguin.com to be sure that it would be Linux-friendly. However, the wireless switch enables / disables all wireless devices including USB. So, there's my $50 donation to the nice folks at thinkpenguin.com, but still no solution. Solution 3? Following the Think Penguin folk's suggestion, modify the mini PCI express adapter following instructions here: http://www.notebookforums.com/t/225429/broken-wireless-hardware-switch-fix Tempting, but I then violate the terms of my warranty mere days after opening the box. This might be a good solution for an older machine that you want to get your geek on with, but not for a new box. Solution 4? rfkill unblock all No effect whatsoever. ubuntu@ubuntu-hp-evny:~$ rfkill unblock all ubuntu@ubuntu-hp-evny:~$ rfkill list all 0: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Solution 5? Re-install drivers. Done and done. Ubuntu recognizes the device - perhaps even without re-installing the drivers? - but cannot turn it on. How do I know this? In the Network Manager drop-down menu, the wireless option is blacked out and a message reads something like: "wireless network is disabled by a hardware switch". Solution 6? Identify a physical switch on the laptop and flip it. There is no such switch on this machine. In fact, walking through Best Buy yesterday, I checked and not a single new laptop PC had a physical switch on it. All of the wireless switches are either the F2 or F12 key ... I wonder if askubuntu will not be plagued by this exact issue in the near future?

  • Common Areas For Securing Web Services

    The only way to truly keep a web service secure is to host it on a web server and then turn off the server. In real life no web service is 100% secure but there are methodologies for increasing the security around web services. In order for consumers of a web service they must adhere to the service’s Service-Level Agreement (SLA).  An SLA is a digital contract between a web service and its consumer. This contract defines what methods and protocols must be used to access the web service along with the defined data formats for sending and receiving data through the service. If either part does not abide by the contract then the service will not be accessible for consumption. Common areas for securing web services: Universal Discovery Description Integration  (UDDI) Web Service Description Language  (WSDL) Application Level Network Level “UDDI is a specification for maintaining standardized directories of information about web services, recording their capabilities, location and requirements in a universally recognized format.” (UDDI, 2010) WSDL on the other hand is a standardized format for defining a web service. A WSDL describes the allowable methods for accessing the web service along with what operations it performs. Web services in the Application Level can control access to what data is available by implementing its own security through various methodologies but the most common method is to have a consumer pass in a token along with a system identifier so that they system can validate the users access to any data or actions that they may be requesting. Security restrictions can also be applied to the host web server of the service by restricting access to the site by IP address or login credentials. Furthermore, companies can also block access to a service by using firewall rules and only allowing access to specific services on certain ports coming from specific IP addresses. This last methodology may require consumers to obtain a static IP address and then register it with the web service host so that they will be provide access to the information they wish to obtain. It is important to note that these areas can be secured in any combination based on the security level tolerance dictated by the publisher of the web service. This being said, the bare minimum security implantation must be in the Application Level within the web service itself. Typically I create a security layer within a web services exposed Internet that requires a consumer identifier and a consumer token. This information is then used to authenticate the requesting consumer before the actual request is performed. Refernece:UDDI. (2010).

  • WebLogic JDBC Use of Oracle Wallet for SSL

    - by Steve Felts
    Introduction Secure Sockets Layer (SSL) can be used to secure the connection between the middle tier “client”, WebLogic Server (WLS) in this case, and the Oracle database server.  Data between WLS and database can be encrypted.  The server can be authenticated so you have proof that the database can be trusted by validating a certificate from the server.  The client can be authenticated so that the database only accepts connections from clients that it trusts. Similar to the discussion in an earlier article about using the Oracle wallet for database credentials, the Oracle wallet can also be used with SSL to store the keys and certificates.  By using it correctly, clear text passwords can be eliminated from the JDBC configuration and client/server configuration can be simplified by sharing the wallet across multiple datasources. There is a very good Oracle Technical White Paper on using SSL with the Oracle thin driver at http://www.oracle.com/technetwork/database/enterprise-edition/wp-oracle-jdbc-thin-ssl-130128.pdf [LINK1].  The link http://www.oracle.com/technetwork/middleware/weblogic/index-087556.html [LINK2] describes how to use WebLogic Server with Oracle JDBC Driver SSL. The information in this article is a guide on what steps need to be taken in the variety of available options; use the links above for details. SSL from the driver to the database server is basically turned on by specifying a protocol of “tcps” in the URL.  However, there is a fair amount of setup needed.  Also remember that there is an overhead in performance. Creating the wallets The common use cases are 1. “data encryption and server-only authentication”, requiring just a trust store, or 2. “data encryption and authentication of both tiers” (client and server), requiring a trust store and a key store. It is recommended to use the auto-login wallet type so that clear text passwords are not needed in the datasource configuration to open the wallet.  The store type for an auto-login wallet is “SSO” (Single Sign On), not “JKS” or “PKCS12” as in [LINK2].  The file name is “cwallet.sso”. Wallets are created using the orapki tool.  They need to be created based on the usage (encryption and/or authentication).  This is discussed in detail in [LINK1] in Appendix B or in the Advanced Security Administrator’s Guide of the Database documentation. Database Server Configuration It is necessary to update the sqlnet.ora and listener.ora files with the directory location of the wallet using WALLET_LOCATION.  These files also indicate whether or not SSL_CLIENT_AUTHENTICATION is being used (true or false). The Oracle Listener must also be configured to use the TCPS protocol.  The recommended port is 2484. LISTENER = (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcps)(HOST=servername)(PORT=2484))) WebLogic Server Classpath The WebLogic Server CLASSPATH must have three additional security files. The files that need to be added to the WLS CLASSPATH are $MW_HOME/modules/com.oracle.osdt_cert_1.0.0.0.jar $MW_HOME/modules/com.oracle.osdt_core_1.0.0.0.jar $MW_HOME/modules/com.oracle.oraclepki_1.0.0.0.jar One way to do this is to add them to PRE_CLASSPATH environment variable for use with the standard WebLogic scripts. Setting the Oracle Security Provider It’s necessary to enable the Oracle PKI provider on the client side.  This can either be done statically by updating the java.security file under the JRE or dynamically by setting it in a WLS startup class using java.security.Security.insertProviderAt(new oracle.security.pki.OraclePKIProvider (), 3); See the full example of the startup class in [LINK2]. Datasource Configuration When creating a WLS datasource, set the PROTOCOL in the URL to tcps as in the following. jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=host)(PORT=port))(CONNECT_DATA=(SERVICE_NAME=myservice))) For encryption and server authentication, use the datasource connection properties: - javax.net.ssl.trustStore=location of wallet file on the client - javax.net.ssl.trustStoreType=”SSO” For client authentication, use the datasource connection properties: - javax.net.ssl.keyStore=location of wallet file on the client - javax.net.ssl.keyStoreType=”SSO” Note that the driver connection properties for the wallet require a file name, not a directory name. Active GridLink ONS over SSL For completeness, there is another SSL usage for WLS datasources.  The communication with the Oracle Notification Service (ONS) for load balancing information and node up/down events can use SSL also. Create an auto-login wallet and use the wallet on the client and server.  The following is a sample sequence to create a test wallet for use with ONS. orapki wallet create -wallet ons -auto_login -pwd ONS_Wallet orapki wallet add -wallet ons -dn "CN=ons_test,C=US" -keysize 1024 -self_signed -validity 9999 -pwd ONS_Wallet orapki wallet export -wallet ons -dn "CN=ons_test,C=US" -cert ons/cert.txt -pwd ONS_Wallet On the database server side, it’s necessary to define the walletfile directory in the file $CRS_HOME/opmn/conf/ons.config and run onsctl stop/start. When configuring an Active GridLink datasource, the connection to the ONS must be defined.  In addition to the host and port, the wallet file directory must be specified.  By not giving a password, a SSO wallet is assumed. Summary To use SSL with the Oracle thin driver without any clear text passwords, use an SSO Oracle Wallet.  SSL support in the Oracle thin driver is available starting in 10g Release 2.
