• Issues with LVM partition size in Server 13.04

  - by Michael

  I am new to ubuntu and a little confused about how hard drive partitions and LVM works. I remember setting up Ubuntu server 13.04 and telling to to use 1TB of a 3TB server. Well I have maxed that out with blu-ray rips and want the rest of the drive for space. On log-in it says: System load: 2.24 Processes: 179 Usage of /: 88.7% of 912.89GB Users logged in: 0 Memory usage: 6% IP address for p5p1: 192.168.0.100 Swap usage: 0% => / is using 88.7% of 912.89GB lvdisplay outputs: --- Logical volume --- LV Path /dev/DeathStar-vg/root LV Name root VG Name DeathStar-vg LV Write Access read/write LV Creation host, time DeathStar, 2013-05-18 22:21:11 -0400 LV Status available # open 1 LV Size 2.70 TiB Current LE 707789 Segments 2 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:0 --- Logical volume --- LV Path /dev/DeathStar-vg/swap_1 LV Name swap_1 VG Name DeathStar-vg LV Write Access read/write LV Creation host, time DeathStar, 2013-05-18 22:21:11 -0400 LV Status available # open 2 LV Size 3.75 GiB Current LE 959 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:1 vgdisplay outputs: VG Name DeathStar-vg System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 4 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 2.73 TiB PE Size 4.00 MiB Total PE 715335 Alloc PE / Size 708748 / 2.70 TiB Free PE / Size 6587 / 25.73 GiB df outputs: Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/DeathStar--vg-root 957238932 848972636 59634696 94% / none 4 0 4 0% /sys/fs/cgroup udev 1864716 4 1864712 1% /dev tmpfs 374968 1060 373908 1% /run none 5120 4 5116 1% /run/lock none 1874824 148 1874676 1% /run/shm none 102400 24 102376 1% /run/user /dev/sda2 234153 56477 165184 26% /boot And fdisk /dev/sda -l outputs: Disk /dev/sda: 3000.6 GB, 3000592982016 bytes 255 heads, 63 sectors/track, 364801 cylinders, total 5860533168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 1 4294967295 2147483647+ ee GPT Partition 1 does not start on physical sector boundary.

• Reading a ZFS USB drive with Mac OS X Mountain Lion

  - by Karim Berrah

  The problem: I'm using a MacBook, mainly with Solaris 11, but something with Mac OS X (ML). The only missing thing is that Mac OS X can't read my external ZFS based USB drive, where I store all my data. So, I decided to look for a solution. Possible solution: I decided to use VirtualBox with a Solaris 11 VM as a passthrough to my data. Here are the required steps: Installing a Solaris 11 VM Install VirtualBox on your Mac OS X, add the extension pack (needed for USB) Plug your ZFS based USB drive on your Mac, ignore it when asked to initialize it. Create a VM for Solaris (bridged network), and before installing it, create a USB filter (in the settings of your Vbox VM, go to Ports, then USB, then add a new USB filter from the attached device "grey usb-connector logo with green plus sign")  Install a Solaris 11 VM, boot it, and install the Guest addition check with "ifconfg -a" the IP address of your Solaris VM Creating a path to your ZFS USB drive In MacOS X, use the "Disk Utility" to unmount the USB attached drive, and unplug the USB device. Switch back to VirtualBox, select the top of the window where your Solaris 11 is running plug your ZFS USB drive, select "ignore" if Mac OS invite you to initialize the disk In the VirtualBox VM menu, go to "Devices" then "USB Devices" and select from the dropping menu your "USB device" Connection your Solaris VM to the USB drive Inside Solaris, you might now check that your device is accessible by using the "format" cli command If not, repeat previous steps Now, with root privilege, force a zpool import -f myusbdevicepoolname because this pool was created on another system check that you see your new pool with "zpool status" share your pool with NFS: share -F NFS /myusbdevicepoolname Accessing the USB ZFS drive from Mac OS X This is the easiest step: access an NFS share from mac OS Create a "ZFSdrive" folder on your MacOS desktop from a terminal under mac OS: mount -t nfs IPadressofMySoalrisVM:/myusbdevicepoolname  /Users/yourusername/Desktop/ZFSdrive et voila ! you might access your data, on a ZFS USB drive, directly from your Mountain Lion Desktop. You might play with the share rights in order to alter any read/write rights as needed. You might activate compression, encryption inside the Solaris 11 VM ...

• Will you share your SQL Server configuration?

  - by Bill Graziano

  I regularly visit client sites and review their SQL Server configurations.  I come across all kinds of strange settings.  I’ve been thinking about a way to aggregate people’s configurations and see what’s common and what’s unique.  I used to do that with polls on SQLTeam.com.  I think we can find out more interesting things if we look at combinations of settings in relation to size and volume. I’ve been working on an application for another project that is similar.  It will be fairly easy to use that code for this.  I can have something up and running in a few days – if people are interested in it.  I admit that I often come up with ideas that just don’t make sense.  This may be one of them.  One of your biggest concerns has be how secure your data is.  My solution is not to store anything identifying.  The instance name and database names can both be “anonymized” and I don’t store the machine name or IP address or anything to do with logins. Some of the questions I’m curious about are: At what size database does the Enterprise Edition become prevalent? Given the total size of the databases how much RAM is common? How many people have multiple data files?  At what size does that become prevalent? How common is database mirroring?  Replication?  Log shipping? How common is full recovery mode?  At what data size does it become prevalent? I think those are all questions that are easy to answer -- with the right data.  The big question is whether or not people will share their SQL Server configurations.  I understand that organizations in regulated or high security environments can’t participate.  But I think that leaves many, many people that can.  Are you willing to share your configuration and learn about others?  I have a simple sign up form here.  It’s actually a mailing list signup that also captures your edition, number of servers and largest database.  The list will only be used for this project.  Is your SQL Server is configured correctly?  Do you wonder what the next step is as your data grows?  Take a second and sign up.

• Best way to remote restart Ubuntu from Windows machine

  - by robsoft

  Background: I'm looking to put a series of Ubuntu machines into retail locations, they're being used as dumb kiosks to show a series of slides onto large LCD panel TV screens. Once installed, they won't have a keyboard or mouse connected but will have a fixed IP on the local network. Everything is configured to auto-start, no automatic updates, no power saving etc - I think we're pretty-much good to go apart from one thing. I need the retail staff to be able to restart the boxes if a problem arises. We have VNC running (now that we've turned off desktop enhancements!) so that we can remotely get into the machines if we need to, but that's not something we would allow the retail staff to do. The machines are going to be physically 'out of the way' (probably in the ceiling space) so the power button is not easily accessible!. I'd like to have some means of allowing the retail staff to restart the Ubuntu machine, from the desktop of one of their Windows terminals. I don't really want to give them some kind of raw terminal access (the command line will frighten them!) and I don't want them to use VNC (as stated above). Ideally there would be an icon on the Windows desktop, they double-click it, reply to a simple 'are you sure?' prompt, and then the Ubuntu box is told to restart. The Windows side of that won't be a problem, we can write something using Delphi, Python & Qt4, whatever - it's the Ubuntu side of it I'm stuck with. Out of sight/view, could I have a Windows program open a terminal across the network and tell Ubuntu to restart? Is this what SSH could be used for (I have never set that kind of thing up). The Windows programming side isn't really an issue, it's just that I'm a total Ubuntu noob and don't know where to start from the platform point of view. The other thing we considered is also having the machine automatically restart itself at a set time each day (obviously out of store hours!). To me, that seems a bit unnecessary (though forcing a restart once a week/month might be worthwhile). Any thoughts or suggestions? Being able to restart the box on demand across the network is my prime requirement.

• determine if udp socket can be accessed via external client

  - by JohnMerlino

  I don't have access to company firewall server. but supposedly the port 1720 is open on my one ubuntu server. So I want to test it with netcat: sudo nc -ul 1720 The port is listening on the machine ITSELF: sudo netstat -tulpn | grep nc udp 0 0 0.0.0.0:1720 0.0.0.0:* 29477/nc The port is open and in use on the machine ITSELF: lsof -i -n -P | grep 1720 gateway 980 myuser 8u IPv4 187284576 0t0 UDP *:1720 Checked the firewall on current server: sudo ufw allow 1720/udp Skipping adding existing rule Skipping adding existing rule (v6) sudo ufw status verbose | grep 1720 1720/udp ALLOW IN Anywhere 1720/udp ALLOW IN Anywhere (v6) But I try echoing data to it from another computer (I replaced the x's with the real integers): echo "Some data to send" | nc xx.xxx.xx.xxx 1720 But it didn't write anything. So then I try with telnet from the other computer as well: telnet xx.xxx.xx.xxx 1720 Trying xx.xxx.xx.xxx... telnet: connect to address xx.xxx.xx.xxx: Operation timed out telnet: Unable to connect to remote host Although I don't think telnet works with udp sockets.

• What is SOA ?

  - by llaszews

  First, let’s mention what SOA is not: • SOA is not the same thing as web services. Web Services implies the use of standard such as Java/JAX-RPC, .NET or REST. Web Services also implies the use of a WSDL, SOAP, and/or J2EE Connector Architecture (J2EE CA) and HTTP. SOA architectures can be implemented using J2EE CA, XML file transfer or Remote Procedural Call (RPC) over File Transfer Protocol (FTP), TCP/IP, Remote Method Invocation (RMI) or other protocols. In other words, Web Services are a very specific set of technologies. SOA is a concept and can be implemented in many different ways. Some very rudimentary, such as transfering flat files between applications. • SOA will not solve all of your problems. It will make your business more agile, increase business visibility, reduce integration costs and provide better reuse. However, if you don’t need help in these area or expect SOA to cure all of your IT problems, you are looking in the wrong place. • The concepts behind SOA are not new, but SOA is also not mature. SOA as it stands today has really only been around for 5 years. The concepts of standards based protocol handlers, predefined communication schemas and remote method invocation have been around for decades. So, what is SOA? SOA is an architectural blueprint, a way of developing applications, and a set of best practices. SOA is not an ‘out of the box’ solution you buy, install and then have up and running in a matter of months. SOA is a journey to a better way of doing business and the technology architecture to support this better way of doing business. SOA is also a broader set of technologies including more then just web services. Techologies like an Enterpirse Service Bus (ESB), Business Processs Execution Language (BPEL), message queues and Business Activity Monitoring (BAM) all are part of a SOA architecture.

• JCP.next.3: time to get to work

  - by Patrick Curran

  As I've previously reported in this blog, we planned three JSRs to improve the JCP’s processes and to meet our members’ expectations for change. The first - JCP.next.1, or more formally JSR 348: Towards a new version of the Java Community Process - was completed in October 2011. This focused on a small number of simple but important changes to make our process more transparent and to enable broader participation. We're already seeing the benefits of these changes as new and existing JSRs adopt the new requirements. However, because we wanted to complete this JSR quickly we deliberately postponed a number of more complex items, including everything that would require modifying the JSPA (the legal agreement that members sign when they join the organization) to a follow-on JSR. The second JSR (JSR 355: JCP Executive Committee Merge) is in progress now and will complete later this year. This JSR is even simpler than the first, and is focused solely on merging the two Executive Committees into one for greater efficiency and to encourage synergies between the Java ME and Java SE platforms. Continuing the momentum to move Java and the JCP forward we have just filed the third JSR (JCP.next.3) as JSR 358: A major revision of the Java Community Process. This JSR will modify the JSPA as well as the Process Document, and will tackle a large number of complex issues, many of them postponed from JSR 348. For these reasons we expect to spend a considerable amount of time working on it - at least a year, and probably more. The current version of the JSPA was created back in 2002, although some minor changes were introduced in 2005. Since then the organization and the environment in which we operate have changed significantly, and it is now time to revise our processes to ensure that they meet our current needs. We have a long list of topics to be considered, including the role of independent implementations (those not derived from the Reference Implementation), licensing and open source, ensuring that our new transparency requirements are implemented correctly, compatibility policy and TCKs, the role of individual members, patent policy, and IP flow. The Expert Group for JSR 358, as with all process-change JSRs, consists of all members of the Executive Committees. Even though the JSR has just been filed we started discussions on the various topics several months ago (see the EC's meeting minutes for details) and our EC members - including the new members who joined within the last year or two - are actively engaged. Now it's your opportunity to get involved. As required by version 2.8 of our Process (introduced with JSR 348) we will conduct all our business in the open. We have a public java.net project where you can follow and participate in our work. All of our deliberations will be copied to a public Observer mailing list, we'll track our issues on a public Issue Tracker, and all our documents (meeting agendas and minutes, task lists, working drafts) will be published in our Document Archive. We're just getting started, but we do want your input. Please visit us on java.net where you can learn how to participate. Let's get to work...

• Correct permissions for /var/www and wordpress

  - by dpbklyn

  Hello and thank you in advance! I am relatively new to ubuntu, so please excuse the newbie-ness of this question... I have set up a LAMP server (ubuntu server 11.10) and I have access via SSH and to the "it works" page from a web browser from inside my network (via ip address) and from outside using dyndns. I have a couple of projects in development with some outside developers and I want to use this server as a development server for testing and for client approvals. We have some Wordpress projects that sit in subdirectories in /var/www/wordpress1 /var/www/wordpress2, etc. I cannot access these sub directories from a browser in order to set up WP--or (I assume) to see the content on a browser. I get a 403 Forbidden error on my browser. I assume that this is a permissions problem. Can you please tell me the proper settings for the permissions to: 1) Allow the developers and me to read/write. 2) to allow WP set up and do its thing 3) Allow visitors to access the site(s) via the web. I should also mention that the subfolder are actually simlinks to folder on another internal hdd--I don't think this will make a difference, but I thought I should disclose. Since I am a newbie to ubuntu, step-by-step directions are greatly appreciated! Thank you for taking the time! dp total 12 drwxr-xr-x 2 root root 4096 2012-07-12 10:55 . drwxr-xr-x 13 root root 4096 2012-07-11 20:02 .. lrwxrwxrwx 1 root root 43 2012-07-11 20:45 admin_media -> /root/django_src/django/contrib/admin/media -rw-r--r-- 1 root root 177 2012-07-11 17:50 index.html lrwxrwxrwx 1 root root 14 2012-07-11 20:42 media -> /hdd/web/media lrwxrwxrwx 1 root root 18 2012-07-12 10:55 wordpress -> /hdd/web/wordpress Here is the result of using chown -R www-data:www-data /var/www total 12 drwxr-xr-x 2 www-data www-data 4096 2012-07-12 10:55 . drwxr-xr-x 13 root root 4096 2012-07-11 20:02 .. lrwxrwxrwx 1 www-data www-data 43 2012-07-11 20:45 admin_media -> /root/django_src/django/contrib/admin/media -rw-r--r-- 1 www-data www-data 177 2012-07-11 17:50 index.html lrwxrwxrwx 1 www-data www-data 14 2012-07-11 20:42 media -> /hdd/web/media lrwxrwxrwx 1 www-data www-data 18 2012-07-12 10:55 wordpress -> /hdd/web/wordpress I am still unable to access via browser...

• Lockdown users on Windows Server 2012

  - by el.severo

  I set up a Active Directory on a server machine with Windows Server 2012 and I'd like to create some users with limitations like Windows Steady State does in Windows XP (locally). Seen already the Windows SteadyState Handbook (with Windows Server 2008), but I'd like to know if anyone has tried this before, the limitations are the following: 1. Prevent locked or roaming user profiles that cannot be found on the computer from logging on 2. Do not cache copies of locked or roaming user profiles for users who have previously logged on to this computer 3. Do not allow Windows to compute and store passwords using LAN Manager Hash values 4. Do not store usernames or passwords used to log on to the Windows Live ID or the domain 5. Prevent users from creating folders and files on drive C:\ 6. Lock profile to prevent the user from making permanent changes 7. Remove the Control Panel, Printer and Network Settings from the Classic Start menu 8. Remove the Favorites icon 9. Remove the My Network Places icon 10. Remove the Frequently Used Program list 11. Remove the Shared documents folder from My Computer 12. Remove control Panel icon 13.

• Usage of Pirated software at a company

  - by hakesh

  Hi, I am redirected from stack over flow since the topic is ethics rather than about programming. Thank you for letting me know that. and please give me advices. So, I started to work at a company as an engineer a couple of months ago. It's a small company and what they basically do is answering service on phones. Now they are switching from normal phones to IP phones so that computers take more important place in the work. However, all the computers used by workers are equipped with pirated software ,even their operating systems are. Moreover, they don't even buy one license to make copies for other computers. In other words, they do not spend any money for the software in office. I am not saying copying a licensed one is legit, but the situation is too much. There is one guy who did installing those pirated soft. He does not feel any sense of guilt and even justified when I asked about it. and he is not even a specialist. He just searched on the internet to install pirated software. Our boss does not have any knowledge of computers, so he took cheaper way. How do you guys think about this? Since I am still new to the company, I am not doing maintenance or managing on those cracked computers. But I have to use those software daily. And later on I will be doing support, help desk kind of staff. I really don't want to take responsibility for operating pirated software. and from an aspect of developer and engineer, pirated software are not able to get legal support and it may work unexpectedly. So, I am thinking about changing job. Am I thinking too much? should I wait until I have more credit from the boss and try to change his policy? So far, the boss does not take any words from me. Any opinions are welcome. Thank you

• How to run WordPress and Java web app running on Tomcat on the same server?

  - by Chantz

  I have to run a WordPress site served via Apache2 & Java-based webapp using Tomcat on the same server. When users come to example.com or example.com/public-pages they need to served from WordPress but when they come to example.com/private-pages they need to be served from the Tomcat. I have asked this question on serverfault where they suggested using different port, different IP & sub-domain. I want to go for different port solution since it will mean I need to buy only one SSL certificate. I tried doing the reverse proxy method by having the following in my default-ssl.conf <VirtualHost _default_:443> ServerAdmin webmaster@localhost ServerName localhost:443 DocumentRoot /var/www <Directory /var/www> #For Wordpress Options FollowSymLinks AllowOverride All </Directory> <Proxy *> Order deny,allow Allow from all </Proxy> ProxyRequests Off ProxyPass /private-pages ajp://localhost:8009/ ProxyPassReverse /private-pages ajp://localhost:8009/ SSLEngine on SSLProxyEngine On SSLCertificateFile /etc/apache2/ssl/apache.crt SSLCertificateKeyFile /etc/apache2/ssl/apache.key </VirtualHost> As you have noticed I am using mod_proxy_ajp in Apache2 for this. And that my Tomcat is listening to port 8009 and then serving content. So now when I go to example.com/private-pages I am seeing the content from my Tomcat. But 2 issues are happening. All my static resources are getting 404-ed, so none of my images, CSS, js are getting loaded. I see that the browser is requesting for the resources using URL example.com/css/* This will clearly not work because it translates to example.com:80/css/* instead of example.com:8009/css/* & there are no such resources in the WordPress directory. If I go to example.com/private-pages/abcd I am somehow kicked to the WordPress site (which obviously displays a 404 page). I can understand why #1 is happening but have no clue why the #2 is happening. Regardless, if there is another clean solution for resolving this, I would appreciate y'alls help.

  I am trying to have an ubuntu box (192.168.10.9) acting as a PXE server, but i have trouble getting DHCP to work. The PXE server is connected to a SOHO router (192.168.10.1) acting as a switch.

• FTP through HAProxy

  - by Menda

  I have a machine, which is the Host and has HAProxy installed in it and working. Then I have a Guest KVM virtual machine running inside the Host with an IP 192.168.122.152. I installed an FTP server in the Guest machine with VSFTPD. From the Host, if I try the command $ ftp -p 192.168.122.152, works perfectly and I can connect to the Guest FTP. I need to remark that this FTP is configured as passive, but both passive and active connections are working from the Host. This is an extract of part of /etc/vsftpd.conf in the Guest: # Passive mode connect_from_port_20=NO tcp_wrappers=YES listen_address=192.168.122.152 pasv_enable=YES pasv_promiscuous=NO port_enable=YES port_promiscuous=NO pasv_max_port=10000 pasv_min_port=10250 Now it's time to make it accessible from outside, so I configure /etc/haproxy/haproxy.cfg like this: listen FTP_Default *:21 server ftp01 192.168.122.152 check port 21 inter 10s rise 1 fall 2 listen FTP_Range *:10000-10250 server ftp01 192.168.122.152 check port 21 inter 10s rise 1 fall 2 But if I try to connect from other machine in internet $ ftp -p $PUBLICIP, it only responds: Connected to <PUBLICIP>, but it doesn't ask for the login and password. Something in the HAProxy config must be wrong, because it's the only point where it fails. By the way, I tried to adapt my configuration to this one in this blog. Thanks.

• Hyper-V Virtual Ethernet Adapter not working probperly - Code 31 on Host

  - by Chris S

  I have a Windows 8.1 machine with Hyper-V installed. From a "clean" Hyper-V configuration I open Virtual Switch Manager, create an External switch with "Allow management operating system to share this network adapter", click OK. Everything seems to work properly but the host loses network connectivity. Opening Device Manager, the "Hyper-V Virtual Ethernet Adapter" is shown under the Network Adapter section with a yellow triangle, and the following message: This device is not working properly because Windows cannot load the drivers required for this device. (Code 31) An object ID was not found in the file. I tried "Uninstalling" the device, seems to work, but the device doesn't actually remove. I tried removing and re-adding the Hyper-V feature completely, no difference. Tried scf /scannow, no problems. System and Application logs show no errors. The Hyper-V-VMMS Networking log shows the following: Log Name: Microsoft-Windows-Hyper-V-VMMS-Networking Source: Microsoft-Windows-Hyper-V-VMMS Date: 10/24/2013 10:53:07 AM Event ID: 26088 Description: Failed to apply static IP settings to internal Ethernet adapter {A813DE9A-BE70-4FAE-AD31-BE4D54505A4B} ('885435B8-BE65-4EE9-826D-AB56035237ED'): Unspecified error (0x80004005). If I try to remove the Virtual Switch in Hyper-V Virtual Switch Manager I get this in that same log: Log Name: Microsoft-Windows-Hyper-V-VMMS-Networking Source: Microsoft-Windows-Hyper-V-VMMS Date: 10/24/2013 11:19:47 AM Event ID: 26142 Description: Failed while removing virtual Ethernet switch. Trying to remove the Virtual Switch leads to an error: Error applying Virtual Switch Properties changes Failed while removing virtual Ethernet switch. VM Networking does work.

• IIS6: Web Site presenting the wrong SSL certificate

  - by pcampbell

  Consider an IIS6 installation with multiple Web Sites. Each is intended to be a different subdomain with its own cert (not a wildcard cert). Each has their host-header specified properly. foo.example.com - port 443. Require SSL w/128 bit. Working properly! It presents its SSL cert properly to the browser. Configured for a specific IP address. bar.example.com - port 443. Require SSL w/128 bit. Configured for all unassigned addresses. When inspecting the IIS property page, it fully shows the cert for bar.example.com on the View Certificate button. This is a NEW web site that is having cert problems. It's presenting the cert for foo.example.com. Ouch! Question: can you have more than one subdomains both running on separate websites with SSL certs on the same port (443)? How would you configure 2 web sites on the same range of 'all unassigned' for the same port (443) ? Update: ignoring the cert error, when browsing to https://bar, the content served is from https://foo site. When NOT using SSL, browsing to http://bar serves the correct content from bar. Just one address is assigned to this DMZ server.

• Access to message queuing system is denied MSMQ?

  - by user1401694

  My problem is a little confusing. I have 2 servers (Windows Server 2008 R2) with MSMQ installed and I want to use Server B to consume a MessageQueue on Server A. When I try to Receive it always throws a message error: "Access to message queuing system is denied.". IP between them. Server A: 172.31.23.130 Server B: 172.31.23.195 FormatName:Direct=TCP:172.31.23.195\private$\queuesource (It's working for Sends) I can ping each server from the other; The firewall is disabled; The "queuesource" has Full Control to "Everyone", "Anonymous Logon", "Network", "Network Services"; Journal is disabled; Authentication is ok; The queue is Transactional. My code in .Net C# is basically like this: MessageQueue _sourceQueue = new MessageQueue(); _sourceQueue.Path = "FormatName:Direct=TCP:172.31.23.195\private$\queuesource"; _sourceQueue.Receive(); // << here throw an exception. Actually I'm using the Private Queue only to avoid Active Directory's problems. For example, if the server DNS fail all network fail. I don't know what do anymore.

• Outlook 2007 unable to connect to exchange server

  - by mattwarren

  I came into the office a week ago and outlook has refused to connect ever since, it just says "Disconnected" in the bottom right-hand corner. I've tried restarting it, rebooting Windows etc. I'm the only one if our office who is having this problem, so it's not a general problem with the server. Things I've tried Pinging the server via IP address and host name, both work fine Connecting via OWA, this works using the same machine name Connecting to Exchange via HTTP ("Outlook Anywhere") doesn't work None of the suggestions in this question helped, http://serverfault.com/questions/21755/can-ping-exchange-server-cant-connect-outlook-to-it Disabling Windows firewall on my laptop also has no effect. There are no items in the event viewer that indicate that anything it up. Also no permissions have changed on the server since when it worked. Update: I've just tried logging onto a completely different PC, using my domain controller user-name/password. When I setup outlook on there it also fails, so the problem isn't specific to 1 pc/outlook it's something about my particular user name, but not when using OWA? What else can I do to diagnose this, any suggestions?

• Configuring VirtualBox host only networking: OSX host, Ubuntu guest

  - by Greg K

  I have a Ubuntu guest configured with two interfaces, eth0 is using NAT and works fine, I can access the net. The second interface eth1 is set to host only networking and VirtualBox has created a vboxnet0 virtual adapter on the host. I've configured vboxnet0 in VirtualBox adapter settings with the following: ip 192.168.21.20 subnet 255.255.255.0 Once the VM guest is running, ifconfig on OSX has vboxnet0 setup as: vboxnet0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 0a:00:27:00:00:00 inet 192.168.21.20 netmask 0xffffff00 broadcast 192.168.21.255 In the guest, eth0 is set to use DHCP, I've statically assigned eth1 to 192.168.21.20 (is this a mistake?): auto eth1 iface eth1 inet static address 192.168.21.20 netmask 255.255.255.0 network 192.168.21.0 broadcast 192.168.21.255 gateway 192.168.21.1 There is no device on 192.168.21.1 - what should I set my gateway to?

• Windows 7 intermittently drops wired internet/lan connection.

  - by CraigTP

  In a nutshell, my Windows 7 Ultimate PC intermittently drops it's internet connection. Why? Background: My PC is wired to my ADSL modem/router which is directly connected to the phone line. I also have wireless connectivity turned on within the router for a laptop to connect wirelessly. Every few hours or so, when using my PC, I find I cannot access the internet and pages will not load. Eventually, Windows7 will update the network icon in the task-tray to show the exclamation mark symbol on the network icon. Opening up the Network And Sharing Centre will show the red cross between the "Multiple Networks" and "The Internet". Here's a picture of the "Network And Sharing Centre" (grabbed when everything was working!) As you can see, I'm running Sun's VirtualBox on this machine and that creates a Network connection for itself. This doesn't seem to affect the intermittent dropping (i.e. the intermittent drops occur whether the VirtualBox connection is in use or not). When the connection does drop, I cannot access any internet pages, nor can I access the router's web admin page at http://192.168.1.1/, so I'm assuming I've lost all local LAN access too. It's definitely not the router (or the internet connection itself) as my laptop, using the wireless connection (and running Vista Home Premium) continues to be able to access the internet (and the router's web admin pages) just fine. Every time this happens, I can immediately restore all internet and LAN access by opening Network Adapter page, disabling the "Local Area Connection" and then re-enabling it. Give it a few seconds and everything is fine again. I assume this is because, beneath the GUI, it's effectively doing an "ipconfig /release" then "ipconfig /renew". Why does this happen in the first place, though? I've googled for this and seen quite a few other people (even on MSDN/Technet forums) experiencing the same or almost the same problem, but with no clear resolution. Suggestions of turning off IPv6 on the LAN adapter, and ensuring there's no power management "sleeping" the network adapter have been tried but do not cure the problem. There does not seem to be any particular sequence of events that cause it to happen either. I've had it go twice in 20 minutes when just randomly browsing the web with no other traffic, and I've also had it go once then not go again for 2-3 hours with the same sort of usage. Can anyone tell me why this is happening and how to make it stop? EDIT: Additional information based upon the answer provided so far: Firstly, I forgot the mention that this is Windows 7 64 bit if that makes any difference at all. I mentioned that I don't think the VirtualBox network adpater is causing this problem in any way, and I also have VirtualBox installed on two other machines, one running Vista Home Premium and the other running XP. Neither of these machine experience the same network connectivity issues as the Windows 7 machine. The IP assignment for the Windows 7 machine is the same both before and after the "drop". I have a DHCP server on the router issuing IP Addresses, however my Windows 7 machine uses a static address. Here's the output from "ipconfig": Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.1.2(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1 DNS Servers . . . . . . . . . . . : 192.168.1.1 NetBIOS over Tcpip. . . . . . . . : Enabled Within the system's event logs, the only event that relates to the connection dropping is a "DNS Client Event" and this is generated after the connection has dropped and is an event detailing that DNS information can't be found for whatever website I may be trying to access, just as the connection drops: Log Name: System Source: Microsoft-Windows-DNS-Client Event ID: 1014 Task Category: None Level: Warning Keywords: User: NETWORK SERVICE Description: Name resolution for the name weather.service.msn.com timed out after none of the configured DNS servers responded. The network adapter chipset is Realtek PCIe GBE Family Controller and I have confirmed that this is the correct chipset for the motherboard (Asus M4A77TD PRO), and in fact, Windows Update installed an updated driver for this on 12/Jan/2009. The details of the update say that it's a Realtek software update from December 2009. Incidentally, I was still having the same intermittent problems prior to this update. It seems to have made no difference at all. EDIT 2 (1 Feb 2010): In my quest to solve this problem, I have discovered some more interesting information. On another forum, someone suggested that I should try running Windows in "Safe Mode With Networking" and see if the problem continues to occur. This was a fantastic suggestion and I don't know why I didn't think of it sooner myself. So, I proceeded to run in Safe Mode with Networking for a number of hours, and amazingly, the "drops" didn't occur once. It was a positive discovery, however, due to the intermittent nature of the original problem, I wasn't completely convinced that the problem was cured. One thing I did note is that the fan on my GFX card was running alot louder than normal. This is due to the fact that I have an ASUS ENGTS250 graphics card (http://www.asus.com/product.aspx?P_ID=B6imcoax3MRY42f3) which had a known problem with a noisy fan until a BIOS update fixed the issue. (See the "Manufacturer Response" here: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121334 for details). Well, running in safe mode had the fan running (incorrectly) at full speed (as it did before the BIOS update), but with an (apparently) stable network connection. Obviously some driver was not loaded for the GFX card when in Safe Mode so this got me thinking about the GFX card (since the very noisy fan was quite obvious when running in Safe Mode). I rebooted into normal mode, and found that Nvidia had a very up-to-date new driver for my GFX card (only about 1 week old), so I downloaded the appropriate driver and installed it. After installation and a reboot, I was able to use my PC for an entire day with NO NETWORK DROPS!!! This was on Saturday. However, on the Sunday, I also had my PC for pretty much the entire day and experienced 2 network drops. No other changes have been made to my PC in this time. So, the story seems to be that updating my graphics card drivers seems to have improved (if not completely fixed) the issue, however, I'm still searching for a proper fix for this problem. Hopefully, this information may help anyone who may have additional ideas as to why this problem is occuring in the first place. (And why does new GFX card drivers have anything to do with the network?) I appreciate everyone's feedback so far. However, I'll have to ask once more if anyone has any further ideas of how to fix this particular problem? Thanks in advance.

• vCenter appliance won't use mail relay server

  - by Safado

  tl;dr: - sendmail is configured to use a relay server but still insists on using 127.0.01 as the relay, which results in mail not being sent. We have the open source vCenter appliance (v 5.0) managing our ESXi cluster. When connected to it via vSphere Client, you can configure the SMTP relay server to use by going to Administration > vCenter Server Settings > MAIL. There you can set the SMTP Server value. I looked through their documentation and also confirmed on the phone with support that all you have to do to configure mail is to put in the relay IP or fqdn in that box and hit OK. Well, I had done that and mail still wasn't sending. So I SSH into the server (which is SuSE) and look at /var/log/mail and it looks like it's trying to relay the email through 127.0.0.1 and it's rejecting it. So looking through the config files, I see there's /etc/sendmail.cf and /etc/mail/submit.cf. You can configure items in /etc/sysconfig/sendmail and run SuSEconfig --module sendmail to generate those to .cf files based on what's in /etc/sysconfig/sendmail. So playing around, I see that when you set the SMTP Server value in the vCenter gui, all that it does is change the "DS" line in /etc/mail/submit.cf to have DS[myrelayserver.com]. Looking on the internet, it would appear that the DS line is really the only thing you need to change in order to use a relay server. I got on the phone with VMWare support and spent 2 hours trying to modify ANY setting that had anything to do with relays and we couldn't get it to NOT use 127.0.0.1 as the relay. Just to note, any time we made any sort of configuration change, we restarted the sendmail service. Does anyone know whats going on? Have any ideas on how I can fix this?

• Configuring default gateway returned by dhcp server

  - by comp1mp

  Hello, I have a machine which connects via ethernet to a private LAN, and wireless to a network which provides internet connectivity. The private LAN uses a wireless router to perform DHCP. The problem is that the wireless and NIC adapters have different default gateways. The default gateway for the private LAN has a lower adapter metric, and is thus chosen by the routing algorithm. I am thus unable to browse the internet when connected to both adapters. The following link has a solution for manually setting the adapter metric to a high number. http://superuser.com/questions/77822/how-to-tell-windows-7-to-ignore-a-default-gateway I was hoping to find a different solution. Does any one know of a router that allows you to configure its DHCP server to return an empty default gateway? I cannot find such an option for my linksys wrt300n. Configuring a static ip address with no default gateway does work, however I would like to use DHCP if possible. Does anyone know of a different way to specify a default gateway for a windows 7 machine with multiple network adapters without mucking with the adapter metric? Thanks, Matthew

• James - mail server configuration help needed

  - by Chaitanya

  Hi, I am trying to setup James mail server on a linux machine. The linux machine has public static ip address assigned. I installed James and added in the config.xml added the servername as mydomain.com. In the DNS for mydomain.com, I have created a A-record, say mx.mydomain.com, which corresponds to the ipaddress of the above mail server machine. Then added mx.mydomain.com as MX record for mydomain.com. In James, I have created a new user test. Then from gmail, I sent a mail to [email protected]. The mail is not received back and it didn't even bounce back. The linux machine is behind a firewall with only 22, 80, 8080 ports open for external network. My question here is, Do I require do open any other ports on the firewall so that the mail I send from gmail arrives to James? If it's not the port problem, any views on solving this issue? I don't want to send mails from this server. It's only for receiving the mails.
