• Install remote desktop session host remotely

  - by Jorge

  I've removed the remote desktop host role from one of my Azue VM, so I can't RDP into it. I have tried to recreate the endpoints and even the VM with no luck. I can't either access remotely with Server Manager; getting this error: The client cannot connect to the destination specified in the request. Verify that the services on the destination is running" I cannot connect remotely to the registry Make sure this computer is on the network, has remote administration enabled, and that both computers are running the remote registry service PsPing tells me The remote computer refuses the network connection Which workaround can I follow to solve this?

• Automatically generated /etc/hosts is wrong

  - by Niels Basjes

  I've created a kickstart script to install CentOS 5.5 (32bit) in a fully automated way. The DNS/DHCP setup correctly gives the system the right hostname in both the forward and reverse lookups. dig node4.mydomain.com. +short 10.10.10.64 dig -x 10.10.10.64 +short node4.mydomain.com. In the state the installed system is right after the installation completed is as follows: cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes GATEWAY=10.10.10.1 HOSTNAME=node4.mydomain.com echo ${HOSTNAME} node4.mydomain.com cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 10.10.10.64 node4 My problem is that this automatically generated hosts file is slightly different from the way I want it (or better: the way Hadoop wants it). The last line should look like this: 10.10.10.64 node4.mydomain.com node4 What do I modify where to fix this? Thanks.

• I have permanent connections to Canonical servers, what are they for and how can I turn them off?

  - by Dan Dman

  After the recent upgrade to 12, I notice permanent connections to canonical servers. Running netstat -tp gives: Foreign Address State PID/Program name mulberry.canonical:http CLOSE_WAIT 6537/ubuntu-geoip-p alkes.canonical.co:http CLOSE_WAIT 6667/python alkes.canonical.co:http CLOSE_WAIT 6667/python Why are there permanent connections and how could I stop this behavior? And if this is intentional, who is responsible? I would like to understand why this was done because to me it seems like a bad idea.

• Can I set up a 2nd home wireless router, with router2 connecting to the internet through a desktop which is wirelessly connected to router1?

  - by gil b.

  Hi, I apologize for the crudeness of my MSPaint drawing, but please view my diagram of what I'd like to accomplish: Proposed home network architecture Currently, all devices are connected to 1 wireless router. I would like to make my own subnet, with a box in-between my subnet and the shared wireless router, so that I can learn about IDS, traffic analysis, etc. I was also given a cisco PIX firewall to play around with, and it'd be an added bonus if I could incorporate that into my network. The reason for this proposed architecture is so that I can monitor all MY traffic, without seeing anything going on with my roommates' traffic. my MAIN Question is, is it possible to have my desktop connect to the wireless router with internet via wireless card AND share that connection via the ethernet card, hooked to wireless router 2? cable modem - wireless router - desktop pc connected wirelessly - wireless router 2 getting internet from wired connection to desktop pc - laptops connected wirelessly The PIX can be left out for now, but I'm wondering if it could eventually be incorporated? THANKS!

• what are the advantages and disadvantages of putting code for an unfinished project on github

  - by cori

  I'm stating to work on a project that I intend to release as open source via the githubs. What are the advantages of putting the code on github from the outset, as opposed to waiting until the project is in a working state before publishing. If it matters, this particular project is a C# app/service, and I have only a free github account (so I can't make it private and then pull back the covers later)

• no way to use opendns on pppoe connection?

  - by magisterludi

  I have an old speedtouch usb modem (revision 0) and on my desktop with xubuntu 12.04 I've configured a pppoe connection. I can connect and my ISP assign an IP address and the DNS but the primary DNS address is not reachable by ping, the secondary yes but no address is resolved then I can't surf the web. Then I want to set the open DNS but there is bo way, if I change manually /etc/resolv.conf it is rewrited by some script (there is the flag usepeerdns on the configuration script, if I exclude it there is no way to assign any DNS server because resolv.conf is not read) also if I set not writable the file changing the default permission. I changed dhclient.conf with the code prepend domain-name-servers 208.67.222.222,208.67.220.220; and now if I connect by a wifi connection to my router I'm using openDNS server but ppp does not use this script as long as I can see and the DNS server is always setted by my ISP. How can I use set DNS manually to a PPP connection? Is there any way to change it after the connection? Why NetworkManager is not able to manage my dsl connection, it seems not able to manage the dsl usb cable modem. If I use pppoeconf NetworkManager doesn't start and I have to manually delete the lines added to /etc/network/interfaces because the system is not able to start with full configuration of network If I connect a modem-router to the same line I can surf with the DNS server assigned by my ISP, I can't figure why. Some suggestion? Thanks to all

• How to re-do the hard disks in a WD Word Book Edition II ?

  - by jfmessier

  I recently purchased a WD World Book II, a 2 TB one. I call it the "White Box". It has those 2 1TB drives, and they were in this RAID 1 config, only giving me about 1 TB. I could not delete the raid array, and I took the drives in a Linux box. But I also deleted the entire partitions of the disks, and I cannot even et the existing RAID array on this WD White Box. The drives are fine, but I cannot get them to work on the WD White Box. My goal was to get back to a real 2 TB storage space. If I cannot get those drives back in the White Box, I can re-use them elsewhere, but this would mean a waste of the firmware and network connection. After the fact, I read that, anyway, the network performance is rather poor. Thanks :-)

• How to set up Windows server 2008 to receive email?

  - by Saul

  First off apologies, I'm from a medical background not a networking one, but I've got roped into setting up a windows 2008 server. So far web server running, fixed IP address assigned (within a large private network of the National Health Service in the UK if that makes any difference) and the network team have assigned a DNS entry for me which works, so the server can be addressed as nww.myserver.nhs.uk I've only got ports open on the router for 80 and 443 (http and https) at the moment, so presume I need a different port to enable email services. My need is to be able to accept an email to the domain name like [email protected] in order to pick up a confirmation mail from an SSL issuer (Comodo) I guess to confirm that I control the domain. After that I don't actually need mail services on the server. I see lots of stuff about setting up SMTP services but thought that was about mail out and re-routing, but how do you get the server to "listen" for mail to the domain (assuming I open port xyz or whatever it is) ?

• Getting 0x80070043 error when accessing Samba share from Windows 7

  - by FelixM

  I created a Samba share on my new Ubuntu 10.04 machine. When I try to access it from a Windows 7 client, I get network error 0x80070043 (The network path not found). However, I get this error when I click on the share in the Windows Explorer, so it seems that Windows does find the path. I already enabled NTLMv1, disabled 128bit security and made sure that NetBIOS is running. I briefly disabled the Windows firewall, it didn't make a difference. What could be the problem?

• Lenovo V570 CPU fan running constantly, CPU core 1 running over 90%!

  - by Rabbit2190

  I have seen that a lot of people are having this same issue. I am running a Lenovo V570 i5 4 core, 6 gigs of ram, and am running 11.10 Onieric Ocelot. On my system monitor graph it shows CPU at 20%, when I open the monitor it shows core #1 at around 90%, the other cores fluctuate at or below 5-12% if even. Now this seems like a really terrible balance of power between the cores, especially with so much stress on one core only, when these things are designed to work with 4 cores and not at such high temps. My current readings say 64 degrees Celsius, this does not seem normal for any cpu, and I am seriously considering, working on my windows7 partition until I see a real solution to this issue or upgrading to 12.04 right away when it comes out... I have seen countless things saying it has something to do with the Kernel, the kernel on mine is the same as when I upgraded, I really do not like messing with it, as when I had 11.04, I did tinker with it due to the freeze issues I was having, and that just made worse issues. I like this version 11.10 and would like to keep it for a while, but without the fear that my core is going to fry! So any help would be much appreciated! I did try changing a couple things in ACPI, and restarting this did not help, and here I am. I tried one thing prior to that that was listed under a different computer brand, but it would not do a make on the file. I really need help with this, I rely on this computer for a lot of things, and love this OS! Please help so I do not need to resort to my Microsoft partition! PLEASE!

• ubuntu server 10 - slow and can't remove desktop environment

  - by Alex

  i'm running ubuntu server 10.10 with the desktop environment. simple page requests are taking over 5 seconds even when connecting to the server through our local network. i believe this is partially related to having the desktop environment installed, as the server worked faster (but not as fast as it should considering that it's on the local network), but tasksel fails every time (aptitude failed 100). my knowledge of networking and linux in general is limited. would really appreciate ideas on how i can troubleshoot this problem. oh also, in the system monitor, one of the processors is almost always around 100%. i doubt this is normal too....

• Replay UDP Packet Capture

  - by inspectorG4dget

  I have a UDP packet capture which was streamed from Port1 on IP1 to Port2 on IP2 on network N1. I need to replay these packets on another network N2 from Port3 on IP3 to Port4 on IP4. I need to know what software to use in order to do this and how I would go about replaying these packets so that I can detect/capture them again in N2. So far, I've tried strictly replaying these packets using a program called Colasoft Packet Player, with little luck. I'd appreciate any help on this. Thank you in advance

• What is the correct way to restart udev in Ubuntu?

  - by zerkms

  I've changed the name of my eth1 interface to eth0. How to ask udev now to re-read the config? service udev restart and udevadm control --reload-rules don't help. So is there any valid way except of rebooting? (yes, reboot helps with this issue) UPD: yes, I know I should prepend the commands with sudo, but either one I posted above changes nothing in ifconfig -a output: I still see eth1, not eth0. UPD 2: I just changed the NAME property of udev-rule line. Don't know any reason for this to be ineffective. There is no any error in executing of both commands I've posted above, but they just don't change actual interface name in ifconfig -a output. If I perform reboot - then interface name changes as expected. UPD 3: let I explain all the case better ;-) For development purposes I write some script that clones virtual machines (VirtualBox-driven) and pre-sets them up in some way. So I perform a command to clone VM, start it and as long as network interface MAC is changed - udev adds the second rule to network persistent rules. Right after machine is booted for the first time there are 2 rules: eth0, which does not exist, as long as it existed in the original VM image MAC eth1, which exists, but all the configuration in all files refers to eth0, so it is not that good for me So I with sed delete the line with eth0 (it is obsolete and useless in cloned image) and replace eth1 with eth0. So currently I have valid persistent rule, but there is still eth1 in /dev. The issue: I don't want to reboot the machine (it will take another time, which is not good thing on building-VM-stage) and just want to have my /dev rebuilt with some command so I have ready-to-use VM without any reboots.

• Internet Working, Browsing Not.

  - by jeffreypriebe

  I have a very odd problem that I can't resolve. I am connected to the internet, but my browsing doesn't work. I don't mean a web browser - I mean browsing. Firefox, Chrome, Curl all fail to successfully connect to an HTTP address. However existing connections, e.g. to mail in Outlook (Exchange Server and also IMAP server) continue to work. Also, the internet is on, I can confirm both from my machine (other ports / connections) as well as from any other computer connected to the same network. Additionally, it appears to be HTTP, not simple a port issue as HTTP over port 8443 (Tortoise SVN if you must know - running over HTTP not over SVN) also fails. I am using Windows Vista SP2 (build 6002). It seems to "creep up" in that after running the computer for a few hours it will fail. (No found way to systematically reproduce the problem.) Additionally, it seems to be more prone on days where the internet connection is flaky already (not sure why the internet is flaky, just is, lot's of failed browsing requests and have to retry/reload often). What I have tried (when the problem arises) - none have yielded any resolution: Resetting the network connection (dis-connect, re-connect) Disable/re-enable the network adapter Double-checked the ip settings Double-checked the HOSTS file. Note: DNS continues to work (both new and cached responses to DNS queries). (Thanks for the suggestion Daniel and antenore.) Checked the routing tables (ip4 only as ipv6 is beyond my understanding) resetting all involved hardware (routers and modems) Close and reopen browsers Looked for malware interference: Run HijackThis Looked for suspicious processes using SysInternals procexp. Looked for explorer hijacks, lsa provider interference, winsock provider interference using SysInternals Autoruns. Run a complete anti-virus scan. Reviewed the output of a netstat -onab to see if there were stuck ports open or unusual processes running somewhere The only thing that works is to do a full reboot. That works 100% of the time to restore browsing. What else can I try to nail down the problem?

• Setup Windows Media Player 11 to stream from TVersity

  - by snorfys

  I've got TVersity installed on a Windows 2003 server box (work had an extra license that they donated to let me install at home to get some practice setting up/administering a domain etc.) I found out that Windows Media Player 11 won't install on Windows 2003, but installed TVersity instead and streaming to my 360 is working great. Problem is that I don't know how to setup streaming to any other PC on the network. All of the PCs have access to the shared network folder, but playing from there doesn't stream and the stutter is pretty bad. Is there a way to setup Windows Media Player 11 or another player to stream from TVersity?

• How to build a 4x game?

  - by Marco

  I'm trying to study how succefully implement a 4x game. Area of interest: 1) map data: how to store stellars systems (graphs?), how to generate them and so on.. 2) multiplayer: how to organize code in a non graphical server and a client to display it 3) command system: what are patters to catch user and ai decisions and handle them, adding at first "explore" and "colonize" then "combat", "research", "spy" and so on (commands can affect ships, planets, research, etc..) 4) ai system: ai can use commands to expand, upgrade planets and ship I know is a big questions, so help is appreciated :D 1) Map data Best choice is have a graph to model a galaxy. A node is a stellar system and every system have a list of planets. Ship cannot travel outside of predefined paths, like in Ascendancy: http://www.abandonia.com/files/games/221/Ascendancy_2.png Every connection between two stellar systems have a cost, in turns. Generate a galaxy is only a matter of: - dimension: number of stellar systems, - variety: randomize number of planets and types (desertic, earth, etc..), - positions of each stellar system on game space - connections: assure that exist a path between every node, so graph is "connected" (not sure if this a matematically correct term) 2) Multiplayer Game is organized in turns: player 1, player 2, ai1, ai2. Server take care of all data and clients just diplay it and collect data change. Because is a turn game, latency is not a problem :D 3) Command system I would like to design a hierarchy of commands to take care of this aspect: abstract Genericcommand (target) ExploreCommand (Ship) extends genericcommand colonizeCommand (Ship) buildcommand(planet, object) and so on. In my head all this commands are stored in a queue for every planets, ships or reasearch center or spy, and each turn a command is sent to a server to apply command and change data state 4) ai system I don't have any idea about this. Is a big topic and what I want is a simple ai. Something like "expand and fight against everyone". I think about a behaviour tree to control ai moves, so I can develop an ai that try to build ships to expand and then colonize planets, upgrade them throught science and combat enemies. Could be done with a finite state machine too ? any ideas, resources, article are welcome!

• Clonezilla-SE with another DHCP Server in LAN

  - by aleroot

  I want to install Clonezilla-Server(192.168.1.100) in a network that already have a DHCP Server (dd-wrt with dnsmasq - 192.168.1.1). I've installed Clonezilla-SE on ubuntu Server 10.10, once installed and configured Clonezilla Server i've removed the DHCP-Server and set pxe server address in dnsmasq configuration on DHCP Server : dhcp-boot=pxelinux.0,,192.168.1.100 When i try to start from PXE a Computer in the network clonezilla start, but give me an error that the ipddress of the machine is not given by the clonezilla server and can't continue ... Someone has already tried to configure Clonezilla-SE in a similar enviroment? Is there some configuration on DRBL server of Clonezilla that i need to do ?

• Replicate GAE Datastore On A Server LAN in Java

  - by Franz Noel

  There may be instances wherein one Company Client may not have internet connection on their vicinity. Either their Internet Service Provider currently experience a down time or there are some other problems involving the network, but not their LAN. GAE seems to be needing a connection at all times in the internet. I only need GAE Datastore. I'm thinking about a different application. Creating a Java Swing Client, for instance, and connecting to the Office Server via HRD of GAE Datastore. When I tried to check on the solutions for Java, it does not say anything about uploading all data and I do not need the App. I just need the GAE Datastore. In Java GAE, only indexes can be able to be manipulated. So, is there any tricks/ideas that you can use HRD with GAE Datastore on Java with an Internal Office Server combined? This way, it may provide service even during network down times. (Can somebody create me a tag of gae-datastore, please.)

• Rsync like windows backup tool

  - by Halfgaar

  Hi, I need to backup some windows machines and have been unable to find the proper tool. What I need is a tool that does efficient copying of changed files to a windows network location, like Rsync does. In turn, the server will then back that up using rdiff-backup, a tool which does very clever incremental backups. Right now I'm using windows' 7 included backup feature, but I really don't get that. It's too much off-topic, but it doesn't suffice (seems buggy as well). I looked into Amanda, but as soon as it wanted to install MySQL, I aborted. I also tried Deltacopy, but unfortunately, I don't remember what the problem with that was... Any advice for an rsync like tool that just does daily syncs to a network location?
