  • Recommendations for Windows Server 2008 Hyper-V VPS Host?

    - by user37042
    I'm looking for a well-respected, high-performing Windows Server 2008 Hyper-V VPS host. For my linux hosting, I use a shared WebFaction account, so I'm spoiled by their incredible service and support. RackSpaceCloud also sounds really good, especially for linux hosting, but it sounds like their Windows hosting is just getting off the ground. I've heard good things about SoftSysHosting, but I didn't know if there were any other VPS providers out there that people will give strong endorsements for (as I do for WebFaction every chance I get).

  • NX Client for Windows 7 Opens Remote Desktop in Multiple Windows

    - by Corey Kennedy
    What I'm trying to do: access my Ubuntu desktop remotely via NX Client on my Windows 7 laptop. My environment: server: Ubuntu 10.10 on AMD 1Ghz/512MB RAM PC client: Windows 7 on ThinkPad sl510 Software: server is running NXServer 3.4.0. Using xfce4 window manager. Laptop is using NXClient for Windows In my NX Client "Desktop" settings I've selected "Unix" and "Custom" for OS and environment. I've also specified "startxfce4" as the application to launch when NX connects. I am able to authenticate an NX session on my laptop. By this I mean, I can start the client on my laptop, enter credentials for my Linux user, and NX establishes a connection to the server and attempts to open a remote desktop window. The problem, though, is that this remote desktop is "fragmented" into many Windows. One window will display the bulk of my desktop (complete with desktop icons for "Home," "File System," and "Trash") while another window will contain the taskbar, and another window will contain the application strip. I can select each of these Windows individually, but I cannot click on any objects within them. I've searched Super User, Ubuntu Forums, NX help, Server Fault, and tried many Google searches - none have turned up another case of this particular problem. I'm stumped. Does anyone have any suggestions for what I might try? I'm guessing the problem has to do with my xfce config files, but I've only just setup this server - it's been a long time since I've used Linux and there's a lot I just don't know. What I am NOT trying to do: use Desktop sharing from Ubuntu, whereby I VNC into a desktop that I've already established on the server. I am trying to configure this Linux box as a headless server that I can stash someplace out-of-the-way in my house, then interact with through my laptop. I don't want to have a monitor or keyboard connected to the Linux box. Thanks for your help! edit: 1/19/2011 Well, this is truly bizarre. To my knowledge I've made no changes to either system - the laptop or the server. But today after starting up the server for the first time in a few days, and making sure that nxserver was running, I was able to connect with the nxclient from my laptop with no problems. I have a full desktop in a single window and I am able to interact with it normally. This is really weird, but the problem seems to be resolved.

  • Is xterm the terminal window we open in Ubuntu

    - by blog.adaptivesoftware.biz
    I know this is a very naive question. I was reading somewhere that Linux allows 7 xterm's. However, I can start more than 7 terminal apps from my Ubuntu system (Application - Accessories - Terminal). There is definetely a hole in my knowledge... will help if someone helped me understand the difference between an xterm and the Terminal application in a Linux distribution such as Ubuntu.

  • Comparison between operational systems

    - by Gustavo Bandeira
    Some years ago, I've heard people saying that the OSX and Linux were better than Windows, I also remember of reading something that said the Solaris operating system didn't fragment their files and that the Linux file system was almost in the same step but none of these claims seemed to have basis or references. I got two questions: When comparing operating systems, what are the main points for comparison? How's the comparison between the main operating systems today?

  • Windows Server 2008 R2 network adapter stops working, requires hard reboot

    - by Geoff Dalgas
    TL;DR version: Turns out this was a Windows Server 2008 R2 kernel networking bug. After siccing Microsoft support on it, we (eventually) got an unpublished kernel hotfix from Microsoft to address it. If you, too, are experiencing mysterious low-level network driver failures requiring a reboot/bluescreen cycle, you might want that hotfix (or maybe Service Pack 1 whenever it is released, too.) We have been using HAProxy along with heartbeat from the Linux-HA project. We are using two linux instances to provide a failover. Each server has with their own public IP and a single IP which is shared between the two using a virtual interface (eth1:1) at IP: 69.59.196.211 The virtual interface (eth1:1) IP 69.59.196.211 is configured as the gateway for the windows servers behind them and we use ip_forwarding to route traffic. We are experiencing an occasional network outage on one of our windows servers behind our linux gateways. HAProxy will detect the server is offline which we can verify by remoting to the failed server and attempting to ping the gateway: Pinging 69.59.196.211 with 32 bytes of data: Reply from 69.59.196.220: Destination host unreachable. Running arp -a on this failed server shows that there is no entry for the gateway address (69.59.196.211): Interface: 69.59.196.220 --- 0xa Internet Address Physical Address Type 69.59.196.161 00-26-88-63-c7-80 dynamic 69.59.196.210 00-15-5d-0a-3e-0e dynamic 69.59.196.212 00-21-5e-4d-45-c9 dynamic 69.59.196.213 00-15-5d-00-b2-0d dynamic 69.59.196.215 00-21-5e-4d-61-1a dynamic 69.59.196.217 00-21-5e-4d-2c-e8 dynamic 69.59.196.219 00-21-5e-4d-38-e5 dynamic 69.59.196.221 00-15-5d-00-b2-0d dynamic 69.59.196.222 00-15-5d-0a-3e-09 dynamic 69.59.196.223 ff-ff-ff-ff-ff-ff static 224.0.0.22 01-00-5e-00-00-16 static 224.0.0.252 01-00-5e-00-00-fc static 225.0.0.1 01-00-5e-00-00-01 static On our linux gateway instances arp -a shows: peak-colo-196-220.peak.org (69.59.196.220) at <incomplete> on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-222.peak.org (69.59.196.222) at 00:15:5d:0a:3e:09 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 Why would arp occasionally set the entry for this failed server as <incomplete>? Should we be defining our arp entries statically? I've always left arp alone since it works 99% of the time, but in this one instance it appears to be failing. Are there any additional troubleshooting steps we can take help resolve this issue? THINGS WE HAVE TRIED I added a static arp entry for testing on one of the linux gateways which still didn't help. root@haproxy2:~# arp -a peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-221.peak.org (69.59.196.221) at 00:15:5d:00:b2:0d [ether] on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 peak-colo-196-220.peak.org (69.59.196.220) at 00:21:5e:4d:30:8d [ether] PERM on eth1 root@haproxy2:~# arp -i eth1 -s 69.59.196.220 00:21:5e:4d:30:8d root@haproxy2:~# ping 69.59.196.220 PING 69.59.196.220 (69.59.196.220) 56(84) bytes of data. --- 69.59.196.220 ping statistics --- 7 packets transmitted, 0 received, 100% packet loss, time 6006ms Rebooting the windows web server solves this issue temporarily with no other changes to the network but our experience shows this issue will come back. Swapping network cards and switches I noticed the link light on the port of the switch for the failed windows server was running at 100Mb instead of 1Gb on the failed interface. I moved the cable to several other open ports and the link indicated 100Mb for each port that I tried. I also swapped the cable with the same result. I tried changing the properties of the network card in windows and the server locked up and required a hard reset after clicking apply. This windows server has two physical network interfaces so I have swapped the cables and network settings on the two interfaces to see if the problem follows the interface. If the public interface goes down again we will know that it is not an issue with the network card. (We also tried another switch we have on hand, no change) Changing network hardware driver versions We've had the same problem with the latest Broadcom driver, as well as the built-in driver that ships in Windows Server 2008 R2. Replacing network cables As a last ditch effort we remembered another change that occurred was the replacement of all of the patch cords between our servers / switch. We had purchased two sets, one green of lengths 1ft - 3ft for the private interfaces and another set of red cables for the public interfaces. We swapped out all of the public interface patch cables with a different brand and ran our servers without issue for a full week ... aaaaaand then the problem recurred. Disable checksum offload, remove TProxy We also tried disabling TCP/IP checksum offload in the driver, no change. We're now pulling out TProxy and moving to a more traditional x-forwarded-for network arrangement without any fancy IP address rewriting. We'll see if that helps. Switch Virtualization providers On the off chance this was related to Hyper-V in some way (we do host Linux VMs on it), we switched to VMWare Server. No change. Switch host model We've reached the end of our troubleshooting rope and are now formally involving Microsoft support. They recommended changing the host model: http://en.wikipedia.org/wiki/Host_model http://technet.microsoft.com/en-us/magazine/2007.09.cableguy.aspx We did that, and.. we'll see.

  • Can I copy my Windows recovery partition to a usb and boot from it?

    - by sherrellbc
    Of course it's not quite this easy, but are there steps for doing this sort of thing? It's a long story but I was dual-booting linux and had a system meltdown of sorts. As such, my Windows bootloader has been erased and I cannot boot into that OS. I do, however, have a linux live-usb through which I have access to my drives. Is there anyway to make use of this recovery partition and boot from itto re-install Windows?

  • Connect to powershell through SSH with keyexchange?

    - by Lucas Kauffman
    I have little experience with Windows systems. Coming from a Linux background I was wondering if there is a way that I can ssh to powershell from a Linux shell? If this is not possible, is there a key exchange like way to connect from powershell to powershell? I prefer it if I do not need to enter a password for every single server every time. If this all sounds a bit crazy and there are better ways that windows does this, then feel free to share.

  • How to build a self-sufficient gcc/glibc/binutils set in a non-standard path?

    - by netvope
    Suppose a set of custom-built gcc/glibc/binutils are in $prefix (e.g. /home/user/path) I want: gcc to look for libraries in $prefix/lib64 instead of /lib64 gcc to look for headers in $prefix/include instead of /include to use $prefix/lib64/ld-linux-x86-64.so.2 as the (hard-coded) loader path instead of /lib64/ld-linux-x86-64.so.2 the dynamic loader to look for shared libraries in $prefix/lib64 instead of /lib64 How should I configure the builds? Do I need to modify gcc's specs file or do anything else?

  • NFS4 / ZFS: revert ACL to clean/inherited state

    - by Keiichi
    My problem is identical to this Windows question, but pertains NFS4 (Linux) and the underlying ZFS (OpenIndiana) we are using. We have this ZFS shared via NFS4 and CIFS for Linux and Windows users respectively. It would be nice for both user groups to benefit from ACLs, but the one missing puzzle piece goes thusly: Each user has a home, where he sets a top-level, inherited ACL. He can later on refine permissions for the contained files/folders iteratively. Over time, sometimes permissions need to be generalized again to avoid increasing pollution of ACL entries. You can tweak the ACL of every single file if need be to obtain the wanted permissions, but that defeats the purpose of inherited ACLs. So, how can an ACL be completely cleared like in the question linked above? I have found nothing about what a blank, inherited ACL should look like. This usecase simply does not seem to exist. In fact, the solaris chmod manpage clearly states A- Removes all ACEs for current ACL on file and replaces current ACL with new ACL that represents only the current mode of the file. I.e. we get three new ACL entries filled with stuff representing the permission bits, which is rather useless for cleaning up. If I try to manually remove every ACE, on the last one I get chmod A0- <file> chmod: ERROR: Can't remove all ACL entries from a file Which by the way makes me think: and why not? In fact, I really want the whole file-specific ACL gone. The same holds for linux, which enumerates ACEs starting with 1(!), and verbalizes its woes less diligently nfs4_setacl -x 1 <file> Failed setxattr operation: Unknown error 524 So, what is the idea behind ACLs under Solaris/NFS? Can they never be cleaned up? Why does the recursion option for the ACL setting commands pollute all children instead of setting a single ACL and making the children inherit? Is this really the intention of the designers? I can clean up the ACLs using a windows client perfectly well, but am I supposed to tell the linux users they have to switch OS just to consolidate permissions?
