• Sharepoint 2010 reacts very badly to having it's IP address changed. How do I fix it?

  - by Jeff Sacksteder

  I have Sharepoint 2010 set up on a virtual host for prototyping various projects. If I restart the host, the IP changes. Afterwards, SP complains that it can't find it's configuration database. I can't find where it might be storing an IP. To clarify, the URL remains the same - I have a dynamic dns solution in place to handle that. I can't see anything in the web.config files or the database connection strings that would indicate a hardcoded IP. How can I fix this up in less time than re-installing every time I need to do a project?

• Set Up Port-Forwarding on Netgear N300 Router

  - by Smitty

  I have a Netgear N300 router that has DynDNS.org as a preset DDNS option. After setting it up it (unsurprisingly) sent traffic directly to my router. I'm essentially using this to connect remotely to my home (virtual) machine/s. From what I've read, it seems like I need to set up port forwarding. I tried forwarding "all" inbound traffic to a specific IP but that just didn't work. What am I doing wrong? Also, I just noticed I get this error after applying the settings: "The specified port(s) are being used by other configurations. Please check your configurations of Remote Management, Port forwarding, Port Triggering, UPnP Port Mapping table, RIP, and Internet connection type"

• file copy error from system to cifs mount

  - by dwpriest

  When coping a file greater than 64kB from an Ubuntu server to a CIFS mounted windows share, most of the data is copied, but it seems the last chunk doesn't get copied. The size doesn't match, and the md5 check sums don't match. I have plenty of file space, but then I use cp, I get the following... cp: closing `cloudBackup/asdf.txt': No space left on device Using rsync, I get the following... rsync: close failed on "/home/fluffy/cloudBackup/.asdf.txt.qrBWe6": No space left on device (28) rsync error: error in file IO (code 11) at receiver.c(752) [receiver=3.0.8] rsync: connection unexpectedly closed (29 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.8] I have full read/write permissions on the mounted share. I can copy via SSH just fine. Any ideas? Thank you

• Windows: Is there something to see and remotely control single(!) windows on a remote PC?

  - by Horst Walter

  Is there something where I can see and control single(!) windows of PC1 on PC2 remotely. Basically like it is possible with X-Windows. I am not talking / asking about A software which displays the whole desktop remotely (like VNC, Windows RDP). A X-windows server for windows, to connect to Linux. The answer here ( Windows Remote Desktop Connection for just a single window (or a single program) ) requires Windows Server 2008. I need to run this on two Windows 7 machines. Example: PC1 shows three windows, and I transfer, see, and control window 2 on PC2. -- Edit -- I have checked whether there is an X-Server for Windows <- Windows. But there seems not to be one other than Unix <- Windows: http://stackoverflow.com/questions/40453/what-is-a-good-and-free-x-server-for-windows

• Problem in multi booting Ubuntu 12.04 with existing Windows XP, 7 and 8 in 500GB HDD with 5 Partitions

  - by Dhruva

  Here's my case. I have 500GB HDD with 5 Partitions with XP, Windows7 and Windows8 RP in the first three. As per one of the instruction I've seen in this forum, I did shrink my 4th Partition to create a 30GB unallocated free space to install Ubuntu 12.04. But, when next I'm trying to boot the Ubuntu CD and choosing "Something Else", its only recognizing my 500GB HDD in whole as "/sda" and not reading the free 30GB space separately to install Ubuntu in it as suggested in the instruction mentioned in this forum. I've also tried to install in from within Windows7, by mounting the Ubuntu ISO file and using the .exe file and instruction thereupon (choosing free drive, user name, installation size, etc.), but that also failed after the PC restarted to continue the installation, showing as error for file extension, partition something error. One thing to be noted that the PC I'm trying to install Ubuntu in it is my Home PC and doesn't have any internet connection. Hence, no updates or otherwise online help. What shall I do?? Kindly suggest. Sorry if I made some grammatical mistakes as English is not my first language. Thanks in advance.

• WGet from one site on a server to another site on the same server

  - by JoshReedSchramm

  Hey all, I've recently been asked to administer a couple ubuntu boxes running web servers. I'm a dev by trade so if this question is fairly noob please forgive. We have about a dozen sites running on this box. 2 of our sites need to talk back and forth over a restful api. Unfortunately we are having issues with the sited connection to each other via wget. When we try and run wget manually from the command line from the server pointing to a site also on that server it hangs and eventually times out. If we do the same thing from outside the server to the same site on the server it works. Is there something that could be preventing sites on the same server from communicating with each other? The same thing happens pinging the site from the server.

• Internet printing : print to iOS gateway -> AirPrint / something -> Laser printers

  - by user75129

  I've done a bit of research on the Internet, and it looks like I'm on a dead end. My goal is to minimize cost, and be able to send and print documents AUTOMATICALLY (may be 10 or 20 pages per day) to a laser printer in a remote office. The preliminary method is to use: iOS 5.1.1 (JB'ed) with 3G connection, HP (or other brands) printer with AirPrint, iCloud's Documents and may be write some launchd scripts to monitor any new documents in iCloud. May be with other software. I am not sure yet. By using the cloud, I can upload new docs to the cloud anywhere in my city, and the iOS will be able to see them within a reasonable amount of time, then print it. But it seems this combo is not workable. Anyone got any advice on how to make this set up work, or propose other alternatives that requires NO PC or Mac? Currently I have a 3GS with 3G connectivity spare. Need to buy a new printer though.

• latency, regular alternations. Pfsense, network

  - by Tillebeck

  Any idea why grapgh is a shown? It i two pfsense boxes and I have not looked into where they ping to and if it is related to the server they ping. Trafic graphs are following a normal 24 hour cycle and not related to either of the latency graphs Img1: High frequent ulteration in latency. Just started a few days back. Peaks are not perfectly regular but varies from 40min to 1hour Img2: This is a different router on another internet connection. Most of our routers shown this kind of latency graphs - so for our setup it is "normal". Please note that second graph is for a whole week and not just some hours

• how to connect virtual box os and local machine

  - by soul

  This question is in connection to this question asked by a user before: http://superuser.com/questions/73470/virtualbox-vdi-file-to-vmware On how to convert vdi to vmdk or vmx using vmware converter. How do I connect the windows xp that is in virtual box to the local computer (windows 7) in a network. Because I got this error while I tried following this instruction: Give the IP address, username and password of the remote machine that you would like to convert and then hit next I got this error in vmware converter: Unable to connect the specified host 10.0.2.15 which is the ip address of the xp machine inside virtual box. It also said that there is a network configuration problem. And when I inputted the ip address from whatismyip.com which should be the same as the ip address on local machine. I didn't get the previous error but I got another one, it said that: insufficient permissions to connect to "ip address" What solution can you suggest for this problem?

• Is it possible to continue torrent downloads from other client

  - by Nrew

  I have downloaded a torrent file but I downloaded it using bitlord. And because bit lord doesnt have the ability like initial seeding. I decided to use utorrent. Ive already tried to continue it. What I did was to: Opened the original torrent file in utorrent. Target where the incomplete bitlord incomplete file was. But it seems that utorrent isn't detecting the file and it makes another copy of it and start to download from the beginning. Im at about 80 percent and there are only 18 seeds but there's 17 leech. And my connection is slow so I really have to initial seed. Other details: I've reformatted the original machine where I downloaded it. Also didn't copy the original application.

• Setting up virtual network in VMware workstation

  - by Saif Bechan

  I am playing around with VMware workstation and am trying to set up a small virtual network. I am having a little trouble with this I hope somebody can help me out. I want to have all the different virtual machines to have different internal IP adresses so I can ping them SSH etc, from within my windows machine. I am directly connected to the internet without a router, so using a bridged connection does not seem to work. The other options NAT and host-only do not seem to work also. I think i need to create a new adapter. I am testing this out with a virtual image of linux debain 5.0 lenny. I have WMware Workstation 7 with virtual network editor. Can anyone guide me in the right direction.

• Is it possible to use 3G internet for a TCP/IP game server?

  - by Amit Ofer

  I'm working on a turned based multiplayer android game with a friend. I started working on the game server and client using socket programming. I found a few tutorials on how to implement a basic chat on android and I started extending that example to suit my needs. Basically the game is really simple and the communication only include sending a few string from the client to the server every turn and sending the calculated scores back to all the clients after each turn. the idea is that one of the players creates the game and thus initialize the server, and each player connects to this client using ip. I tried this solution and it seems to work great when all the players are using the same wifi connection or by using router port forwarding. The problem is when trying to use 3G internet for the server, I guess the problem is that 3G ip address isn't global and you can't use port forwarding there, correct me if I'm wrong here. Is there a way to overcome this issue? or the only solution is to limit my game to wifi only or think of a different solution than the standard socket programming solution? I.E web server etc. what do you think would be the best approach here? Thanks.

• Installing CentOS 6.3 wrong hard drives order?

  - by Ken Tang

  I am trying to install CentOS 6.3 on new server that has 2xSSD and 1xHDD drives connected to mainboard's SATA ports by following order: SSD1 -> SATA1 SSD2 -> SATA2 HDD1 -> SATA3 On the installation process CentOS shows me hard drives by this order: /sda -> that is actually SSD2 /sdb -> HDD1 /sdc -> SSD1 It looks like CentOS assigns it randomly rather by the SATA connection order. My question is: What the order of drives /sd* depending on? And how can I change it to be by the order it connected to SATA? Thank you in advance!

• How to start Ubuntu with no working video card?

  - by ViliusK

  I have a laptop with broken video card. It has two operating systems installed - Windows 7 and Ubuntu 10.10 Desktop Edition. It has GRUB to manage which operating system to boot up. Windows is default OS. And Windows fails to boot up without video card. I'm checking with ping to the ports which are shown as used by DHCP in my router. Normal boot of Ubuntu also fails and it restarts after a while. But when I choose (blindly, but checking HDD indicator and by counting button presses when GRUB menu appears) to boot second option of Ubuntu (rescue mode) it starts and I can ping it. But when I try to connect to it through SSH, I'm getting "connection refused" error from putty. I've took out HDD from my laptop already and inserted it to WD Passport case so now I can connect it to other computer to edit configuration files. How can I check if SSH server is working? How to enable it in rescue mode? Or better, how to disable video card to be required while booting Ubuntu in normal mode?

• Does PCI bus really occupy 1.8GB

  - by Neil

  I am using a Dell Vostro 1700 laptop which currently has 2GB of RAM. I was considering buying some more memory to upgrade it to 4GB. I am running 32 bit Windows Vista and I know that there can be issues that prevent it from making use of a full 4GB which I believe relate to the fact that memory mapped devices, e.g. graphics card, also need to be allocated addresses in the 4GB range addressable with 32 bits. Consequently I was looking at device manager - resources by connection - memory to see what devices where allocated what memory addresses. I was surprised to see that there was an entry for [80000000 - F3FFFFFF] PCI bus. That is a 1.8GB range of addresses. When I expanded it the only thing in it was [E0000000 - EFFFFFFF] NVIDIA GeForce 8600M GT which is only 256MB. So my question is does the PCI bus really occupy 1.8GB of address space and will it prevent my computer from making use of any more memory than it already has.

• windows cache not working as it should?

  - by piotrektt

  I run windows 2012 server with data center. The setup is with 60GB of RAM. I have one file shared on VHD and when I copy this file locally the RAM cache is all used up but when multiple computers connect to the share it the cache is not used. The network is 8Gb. The whole network is around 200 computers that need to read that one file but on this setup only 10 connection kills the server. Is there any way to check what is going on? What other solution can I use to manage cache in windows?

• is there a cheatsheet for linux commands to save your system?

  - by Asaf

  I've recently lost my window options, had to somehow manipulate my way to Xchat and ask some people how do I get it back (it was metacity --replace, and after I decided to stop the command and run it in background the X was completely useless so I had to do killall -u user). And that was after the internet connection stopped working for some reason (might've been the ISP) ..The thing is, after using linux a long time, I still get the feeling that on dire situations, I don't know the good tricks (stuff like metacity --replace) I feel like a really need like a "rescue" cheatsheet for things like "how to save the X no matter what without pressing reset" and "how to reset the system to "normal state"" "how to connect to the internet through the command line" "how to monitor what the X is doing" (using ubuntu linux 10.04 btw)

• How to configure a static wildcard subdomain with dnsmasq.

  - by Prody

  I have a network behind a NAT with a few machines. The machines are: router - NAT, dnsmasq, forwarding - directly connected to the inet server - which runs ssh, www and some other stuff clients - which do stuff on server I also have mydomain.com. server.mydomain.com is pointing to my connection's IP (single IP), which is the router, which forwards ports to server. Server, has a httpd running, which serves different sites based on vhosts. So I have site1.server.mydomain.com, site2.. The problem is that all the traffic is going thru the router, and when I check logs I always see the router's IP for everything (so it's hard to see who is running the script with the while(1)). I would just ServerAlias site1.server.local, but most of the sites have a root URL saved somewhere on top of which other URLs are built, so I can't do that. The solution for me would be telling dnsmasq somehow to answer to *.mydomain.com with server's IP. Is this possible somehow?

• Windows 7 with two network cards doesn't route traffic

  - by Tomek

  I have simple task to do: I have wni7 with two nics.I want to connect another comp(osx) to win7 through second nic to connect it to internet. I already changed the registry. Win7 interface with 192.168.2.1 has no gateway set (no point to do that) OSX interface with 192.168.2.2 has gateway set to 192.168.2.1 I do not add any routes on win7, every thing seems to be already there network on second nic is detected as "undefined network" (probably effect of no gateway) i can achieve any connectivity to internet from OSX only by enabling network connection sharing on nic with 192.168.2.1, but it enables NAT and I'm interested only in pure routing without nat(it's a setup for some research). firewall is off. It seems to me that win7 refuses to forward packets for some reason. Perhaps "undefined network" and NLA service is to blame, although i couldn't find any info about that. Below ascii schematics of my setup: internet<--router(192.168.1.1)<--(192.168.1.1) WIN7 (192.168.2.1)<--(192.168.2.2)OSX Thanks
