  • Linux (Ubuntu 12.04) two gateways one nic

    - by David
    I have Ubuntu 12.04 Server edition Two gateways, both on 192.168.0. network, let's make them 192.168.0.1 and 192.168.0.2 I've read you should be able to add second gateway into /etc/network/interfaces, that it will build out all the routing automatically, but I get "duplicate option" error. So if I have one default gateway, let's say 0.1, and a connection comes through from the 0.2 gateway, my understanding is that it still tries to respond through 0.1 gateway. Can we change this behavior?

  • Remove a file on linux using the inode number

    - by WebDevHobo
    If you create a file on UNIX/linux with special chars, like touch \"la*, you can't remove it with rm "la*. You have to use the inode number(you can if you add the \ before the name, I know, but you'd have to guess as a user that it was used in the file creation). I checked the manpage for rm, but there's no metion of the inode number. Doing rm inodenumber doesn't work either. What is the command for this?

  • Read-only access to MMC functionality

    - by Travis Ingram
    Does anyone know of a Windows Server 2008 role(s) to allow readonly access to MMC (MS Management Console) facilities - i.e. we would like to be able to view (not add/update/delete) "Administrative Tools" functionality such as IIS websites, Event log, Users and groups, status of services, etc. This is so we can connect to a say a Development server (administered by another team) to check configuration before/during deployment via say Administive Tools | Computer Management | Connect to another computer Many thanks Travis

    - by sKIPper76
    When I have anon-access = write Everything works fine. When I change svnserve.conf to: anon-access = none auth-access = write And uncomment password-db and authz-db AND add user in authz with rw AND put username/password in passwd, nothing works. Eclipse keeps giving me a "Cannot map the project with svn provider" error. I have given all the files under conf 777. Any ideas what's wrong?

    - by hvtuananh
    My company's router is Zyxel P-320W and I have a public static IP. I registered a few domains name and point to this IP address. I already setup Virtual Hosts and configured port-forwarding to my internal server and it works well. I can connect to all domains from outside The problem is I cannot connect to my domains from inside One workaround way is modify hosts file to add internal IP for those domains, but my company have many computers and I don't want to setup all PC manually

I made a text file containing "foo" and did PS> cat .\test.txt | ncat -u 192.168.1.255 6061 but that also adds CRLF

    - by l0l0l0l0l
    Login Windows load modern UI Only when I click on the "Desktop" tile shortcut that my desktop is really loaded, it take a few seconds to open everything (like rainmeter and other things) How can I make windows load both modern UI and my desktop on the background? I don't want to skip the modern UI just autoload the desktop. Similar to add something.exe to the startup, but what executable should I use? I've tried explorer.exe but didn't work.

  • How to merge two different Makefiles?

    I have did some reading on "Merging Makefiles", one suggest I should leave the two Makefiles separate in different folders [1].

I don't know what they exactly do. What I want is to merge the two of them so I get only one binary. The code compiled in the second Makefile should be the result. I want to add flexibility.cpp and constraints.cpp to the second Makefile, but when I do. I get the problem following problem: flexibility.h:4:26: fatal error: ClpSimplex.hpp: No such file or directory #include "ClpSimplex.hpp" So the compiler can't find the Clp library. I also tried to copy-paste more code from the first Makefile into the second, but it still gives me that same error. Q: Can you please help me with merging the two makefiles or pointing out a more elegant way? Q: In this case is it indeed better to merge the two Makefiles? I also tried to use cmake, but I gave upon that one quickly, because I don't know much about flex and bison.

  • Why don't I have a "Web Service References" menu item in excel/VBA?

    I'm trying to consume a SOAP web service from excel. Now according to This article (and confirmed by other articles and MSDN) if I do the following: Install the web services toolkit (I've installed v2.01) Install SOAP Toolkit 3.0 Add a reference to Microsoft Soap Type Library (I've tried v3.0 and an older one) I should get a "Web Service References" menu item in the Tools menu but I don't. I've also tried adding every reference that seemed to have anything to do with SOAP or XML, but it hasn't helped. Any ideas?

  • Configuring only one Internet Explorer zone (IntranetZone) thru GPO without affecting other zones?

    I need to deploy some trusted intranet sites into Intranet Zone in Internet Explorer. It works fine when using GPO at: Setting Path: Computer Configuration/Administrative Templates/Windows Components/Internet Explorer/Internet Control Panel/Security Page Supported On: At least Internet Explorer 6.0 in Windows XP Service Pack 2 or Windows Server 2003 Service Pack 1 Problem is this settings also affect other zones making it impossible for people in company to add sites to other zones themselves. Is there a way to fix this so that Intranet Zone is deployed thru GPO and rest of settings stay in gesture of users?

  • Checkpoint Endpoint Connect Imaging - Are there any gotchas?

    - by Ben
    I am about to install CheckPoint EPC on a load of new laptops being rolled out. I plan to add it to the image, but want to check if there are any gotchas? By this I mean are there any UIDs that need removing before the image is taken to "depersonalise" the install. For example when you install LANDesk or McAfee (when using ePolicy) you need to remove the identifiers - do I need to do the same with EPC? Thanks in advance, Ben
