• How to move a partition to the end in gparted?

  - by matnagel

  I can't find a way to move the partition /dev/sdb2 to the end, where 12GB are free http://dl.dropbox.com/u/3358699/permanent/gparted-sdb.png I can resize (expand) the partition, but not create (insert) any free space in front of it. How to do the trick? (There are 2 small black arrows on the top of the popup window in the screenshot at the side of the blue box that represents the 400 GB sdb2 - I can only move the right arrow to the right, which extends the size, but I cannot move the left arrow. When I enter something in the free space preceding box it is always reset to zero by the programm immediateley) I hope I explained this well enough, please feel free to ask for details. This is serious for me as I am expanding a live image. Maybe there is another solution with linux commandline tools ?

• Manage a lot of open ssh sessions to servers with id's for hostname

  - by kimausloos

  Lately I'm working a lot with a few open ssh connections to multiple VPS servers. The hostnames of the servers all follow an ID approach and it's becoming very difficult to know on what machine I'm working with. I was wondering if there is a way to put a name I define somewhere as the title of the terminal. So I would, for example, associate IP 123.123.123.123 with webserver-stg. When opening the connection to the IP, webserver-stg would automaticaly be displayed as the name of the session. Of course I'm not able to change code on the VPS servers, so the solution should be client-side.

• asterisk outbound caller id

  - by MCS

  I'm trying to set the caller id number for an outbound call. My asterisk .call file looks like this: Channel: SIP/flowroute/1234567890 Context: test Extension: 1234567890 Priority: 1 Here's my extensions.conf: [test] exten => _1NXXXXXXXXX,1,Set(CALLERID(num)=8005552222) exten => _1NXXXXXXXXX,n,Dial(SIP/${EXTEN}@flowroute) exten => _1NXXXXXXXXX,n,Playback(hello-world) When I receive the call, the caller id number is 1-206-445-6979, even though the CDR log has both src and clid set to 8005552222. I'm using flowroute as my carrier. Is there something wrong on their side?

• Multicast File copy with Unicast responses

  - by kirbuchi

  I'm trying to do some multicast big file copies over to remote clients on the other side of a satellite link. The idea is to minimize the amount of traffic going up to the satellite. I tried using uftp without luck. The problem is that, even though we can reach clients via multicast from our central Hub, they aren't able to respond to a multicast address (it's not supported by the return link). As uftp needs to respond to a multicast address in order to report any missing packets I'm out of luck. So does anyone have any recommendations or alternatives I can use to do the trasfers? Any tip or pointer would be appreciated.

• IPSec VPN IP addresses

  - by Randomblue

  I have an IPSec VPN on my Windows 7 machine (all using the native Windows 7 gateway). The host I am connecting to has different ISAKMP "Phase 1" and "Phase 2" IP addresses. As I understand, the Phase 1 address is that of the IPsec endpoint, to which I can connect just fine. The Phase 2 address is found in their "crypto map", and the addresses need to match. At the moment, both my Phase 1 and Phase 2 addresses are configured the same. On my side, I get the error "Error 791: The L2TP connection attempt failed because security policy for the connection was not found" How can I configure the Phase 2 IP address for my Windows 7 IPSec VPN to be different to the IPSec endpoint address?

• Routing DHCP traffic over the internet

  - by rmanna

  i'd like to know if it's possible for the internet to be between a DHCP server and the network it's "assigned" to? so basically, something like this: -------------- ------------- ------------- | DHCP Server | | DHCP | | Clients | | |-----Internet-----| Relay Agent |------| 192.168.0.* | | | | 192.168.0.1 | | | -------------- ------------- ------------- the behavior i'm seeing is that the DHCP server is offering 192.168.0.* IPs and sending them back to 192.168.0.1, which it can't reach. i tried masquerading the packets sent by the relay agent but that doesn't seem to work. from what i've been reading, this is normal behavior since the DHCP server uses the GIADDR as the destination address for its OFFERs, and not the actual source IP of the packets it receives from the relay agent. sooo, given that my DHCP server needs to be "on the other side of the internet" as depicted above, how can i get this working? are there settings for dhcpd to do this or is creating a VPN containing the DHCP server and the relay agent the only way? thanks!

• Accessing to shared folders with OpenVPN

  - by Ergec

  This is my first attempt to configure a vpn so I have very little knowledge about this. Network where centos server is having local IPs 192.168.123.* Network where windows machine is having local IPs 192.168.1.* I installed and configured my openpvn server on centos 5 and client on a windows machine. Generated all keys, certificates e.t.c and transferred them to client and I'm able to connect to server. Below there is a screenshot of the client log. Also on server side I can also see incoming packets with this command tcpdump -n port 1723 So I assume I did most of the things correct. But still when I try to open shared folders using \\192.168.123.33 or \\network-name I can't access folders

• 3 Monitors on a Notebook

  - by Rihan Meij

  I would like to use 3 screens on my Dell Inspiron 1720 So On the laptop built in screen have that as one, and then have 2 more screens. The catch is, that I want to play racing games with this set-up. So that my main screen is the focus area (the front window if you will) and the other 2 screens will be used for peripheral vision, on the side. The software that I use (LFS.net) does support multiple screens. However the notebook can have the main screen on, and another external screen. So I would need to split this "second" monitor output, to 2 screens, the one to the left of the main monitor, and the other one to the right. Is this possible? Is there perhaps a external card / docking station solution that could help with this? Any advice or ideas is greatly appreciated. Best Regards Rihan

• Is there a direct URL to download Java JDK updates?

  - by Bob Cross

  I have a whole set of machines that are on the other side of a firewall configured to prevent all Javascript from functioning. All of them (Linux 32 and 64 bit configurations) must be updated to Java 6 update 20. This is a problem given Sun/Oracle's URL redirector and download manager: they simply don't appear or don't work. Is there a URL to download the JDK updates and bypass the redirect? Obviously, a yum configuration that would allow for automatic updates would be optimal but I'd be happy to just have the rpm file.

• Server 2003 slow share.

  - by G V

  I am running an 03 box with shares active. When uploading to the share, the speed is average. About 15-20 mbps.. But when you think about it, it is bad because it is a direct connection to a couple machines. When uploading to another server the connection speed is twice that of the direct storage. When uploading s massive folder, 250 GB, the upload will start as normal, but as it progresses it drops in speed. Now it is sitting at around 2-7 Mbps. Any ideas on how i can boost the transfer rate? On a side note, the download speed is great. It is a speed that you would expect from this setup, the main problem is uploading and what is causing the extreme slowness in speeds. Any help would be great.

• Optimize Windows file access over network

  - by Djizeus

  At my company I frequently need to access shared files over a Windows network. These files are located on the other side of the planet, so I guess the file share goes through some kind of VPN over Internet, but I don't control this and it is supposed to be "transparent" for me. However it is extremely slow. Displaying the content of a directory in the file explorer takes about 10s. Even if over the Internet, I did not expect that retrieving a list of file names would be that long. Are there any settings to optimize this from my Windows XP workstation, or is it mostly related to the way the network is configured? The only thing I have found so far is to cache all file names, while by default only short file names are cached (http://support.microsoft.com/kb/843418).

• Converting an Small Business Server to a Workstation

  - by noway

  I am planning to buy a Dell PowerEdge T110 Server and convert it to workstation similar to Dell PowerEdge Precision T1700. The reasoning behind is the cost, if I do it by myself, it costs two times cheaper. However, I wonder what might go wrong in this way? The things I have thought of are: Client OSes are not officially supported. There might be some driver problems. The chasis is designed to be a server case, so there are not many useful inputs in the front side of the case. The server boots slower than usual PCs. What might else be a problem?

• Can mod_rewrite Conditions/Rules be executed in random order?

  - by Tom

  I have some mod rewrite rules that test for the presence of a file on various NFS mounts and I would like that the tests occur randomly, as a very rudimentary way to distribute load. For example: RewriteEngine on RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount1/%1 -f RewriteRule ^/(.+)$ /mnt/mount1/$1 [L] RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount2/%1 -f RewriteRule ^/(.+)$ /mount2/$1 [L] RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount3/%1 -f RewriteRule ^/(.+)$ /mnt/mount3/$1 [L] RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount4/%1 -f RewriteRule ^/(.+)$ /mnt/mount4/$1 [L] As far as I understand mod_rewrite Apache will look for the file on /mnt/mount1, then mount2, mount3 and so on. Can I randomize this on each request? I understand this is an odd request but I need a creative solution to some unforeseen downtime. On a side note, do I need to redeclare RewriteCond %{REQUEST_URI} ^/(.+)$ each time like I have done? Thanks

• Server 2012 file server security - File access through software only?

  - by user1607914

  I have just setup a server 2012 essentials R2 box as a test bed for my small business. Its running Essentials R2 as a VM on a Essentials R2 host. I have set it up to be the DC and DHCP server and joined a client. My next task is to use it as a file server but I am not quite sure how to set it up. All the client interactions with the file server will be through client side software. I therefore do not want any access to the files apart from through the software. I have looked at the ntfs permissions and there is a permission called "List Folder/Read Data" however I am unsure this will do what I want. Is it possible to give access to the files but not allow access through the windows explorer / command line?

• Create a term-document matrix from files

  - by Joe

  I have a set of files from example001.txt to example100.txt. Each file contains a list of keywords from a superset (the superset is available if we want it). So example001.txt might contain apple banana ... otherfruit I'd like to be able to process these files and produce something akin to a matrix so there is the list of examples* on the top row, the fruit down the side, and a '1' in a column if the fruit is in the file. An example might be... x example1 example2 example3 Apple 1 1 0 Babana 0 1 0 Coconut 0 1 1 Any idea how I might build some sort of command-line magic to put this together? I'm on OSX and happy with perl or python...

• IIS and Apache on the same machine?

  - by MLS

  I have a Windows 2003 Server running IIS (due to an ASP Site needing to be hosted). I wanted to add some non ASP sites (HTML, PHP and MySQL) so I was thinking I could just run apache on 8080. What confuses me a bit is if someone hits DomiainA.com, IIS intercepts it and forwards it to DomainA.com:8080 where apache is running. I could do this by putting a server side javascript re-direct in the IIS www-root for the domain. What else can I do that might be more proper?

• Vertically resize two windows at same time?

  - by Guy

  I love the new feature in Windows 7 where I can grab the title bar and "slam" a window against the right edge of the computer and it will size that window to the right half of the screen. I can then grab another window and do the same against the left side of the screen. Once I've done that I often find that one of those windows needs a bit more horizontal space and the other can do with less. So I grab the edge in the middle of each window and resize that window so I can most efficiently use my screen space. Problem is that I have to do this twice, once for each window. Is there a way to grab the inside vertical edge of both windows at the same time so that I can make one wider and the other smaller at the same time?

• Remote Desktop closes with Fatal Error (Error Code: 5)

  - by Swinders

  We have one PC (Windows XP SP3) that we can not log onto using a Remote Desktop session. Logging on to the PC directly (sitting in front of it using the connected keyboard and monitor) work fine. From a second PC (tried a number of different ones but all Windows XP SP3) I run 'mstsc' and type in PC name to connect to. This shows the login box which we can enter the correct login details and click OK. Within a few second we get an error: Title: Fatal Error (Error Code:5) Error: Your Remote Desktop session is about to end. This computer might be low on virtual memory. Close your other programs, and then try connecting to the remote computer again. If the problem continues, contact your network administrator or technical support. None of the computers we are using are low on memory (2Gb+) and we let windows manage the virtual memory side of things. We do not see this with any other PC and do use Remote Desktop in meeting rooms to connect to user PCs with no problems.

• Allow Internet Access with Default Gateway on Windows 7 VPN Server

  - by Hakoda

  I have a Windows 7 box at home (which I'll refer to as Home-VPN) that runs a simple PPTP VPN server. I have a range of 2 IP address (192.168.1.10-192.168.1.11) to give out, although the server is only able to give out one concurrent connection. Ports 1723 & 47 are correctly forwarded to the server. IPv6 is disabled on both Home-VPN and the client. I setup Home-VPN just like this Youtube video: http://www.youtube.com/watch?v=1s5JxMG06L4 I can connect to it just fine but I can't access the Internet when connected to Home-VPN, all outside web servers (eg. google.com, mozilla.org, apple.com) are unreachable. I know I can uncheck "Use Default Gateway on Remote Servers" on the client side under IPv4 settings but that will route all my traffic through my current connection, rather than through the VPN, defeating the purpose of said VPN. Any ideas on how I can fix this?

• Sound feels to come from far in my headphones [closed]

  - by Rakesh

  I bought new headphones just yesterday. The strange thing is when I hear sound from my headphone I feel like it is coming from far away. Main problem comes in games, when I hear the footsteps of enemies and think he is on the other side of the wall while he is near to me. :D I also heard virtual haircut on youtube . I tried this with my new headphones and HTC desire S earphones. In case of HTC earphones I felt that scissors and electric razor( @ 3:04 ) is too much near to my ear but in case of the headphones I didn't felt such thing. I felt electric razor is almost 6 inches away from my ear. Have you ever encountered such problem? What can I do in this case?

• Is IPv6 multicast routable over the Internet?

  - by Absolom

  As I understand it, public IPv6 addresses allocated by the IANA will have the prefix 2000::/3. These ip addresses will be routable through the Internet. IPv6 multicast addresses on the other side are prefixed FF00::/8. So my understanding is that the ipv6 multicast addresses won't be routable through the internet. I am right? If so, is there any way to do one-to-many ip routing over the Internet in IPv6? Thanks!

• good books about server architecture?

  - by ajsie

  when the traffic for a website grows i dont think one apache server in a vps is the way to go. i would like to know more about how i then should set up the server side architecture. im not that much into hardware stuff (what kind of cables to use, different cpu architectures etc), but interested in the software architecture: what servers (apache, nginx, squid, varnish etc) to use and how they interact with each other one server in one machine? how many mysql servers. how many apache, nginx servers and so on. how the "machine court" looks like. are there any good books about this area?

• Resize a new database to predicted maximum size

  - by John Oxley

  Currently I have a SQL Server database which is about 2 Gb. I know over the next year it's going to grow to a maximum of about 10Gb. Hard drive space is not an issue in the slightest. Is there a down side to resizing the datafile to 20Gb now, then defragmenting the hard drive? Should I resize the log file to 1Gb as well? Something ridiculously large so that fragmentation doesn't happen there either. With this question I would like to avoid the datafile becoming fragmented on the disk itself, but I don't want to negatively impact performance.

• Fix X11 forwarding on OSX

  - by Such

  I am looking for a way to fix/debug a X11 forwarding session on OSX. Here is my situation: From my mac I connect to a Ubuntu workstation with ssh -X (tried ssh -Y as well). X11 forwarding works perfectly with firefox for instance, X11/Quartz is started automatically on OSX and firefox is displayed. X11 forwarding does not work with bat (Bacula graphical console): X11 is started but no window is displayed. There are no errors (/private/var/log/system.log). When I try doing the same from another Ubuntu workstation, it works perfectly for both firefox and bat. I guess the problem is on OSX side then. I tried switching some options in X11 but nothing works. Would you have any idea on how to move forward? Thanks!
