  • Ubuntu inside VirtualBox is slow

    - by Kapsh
    I am running an Ubuntu instance on VirtualBox inside XP. Here are the details: Host: Windows XP Pro Guest: Ubuntu 8.10 Total RAM: 3GB RAM For VM: 1GB Total Video Memory: 128MB Video Memory for VM: 40MB Hard Drive: 200GB Hard Drive for VM: 30GB Processor: 2.80GHz Core Duo The problem is that whenever I am inside the virtual machine, things seem so much slower in general. For example Firefox, Eclipse take longer to load, dragging windows show a lag etc. I have tried running Ubuntu before (not inside a VM) and it seemed fantastically fast. So I am disappointed to have to deal with this situation. But I need access to the XP partition without having to reboot and hence the attempt. I am surprised with the perceived slowness since the whole world seems to be doing virtualization and I cannot imagine everyone works on slow systems knowingly. My question is - is there something I should be doing to boost performance? Am I doing something wrong? This is my home machine and I am not sure if this is the right forum to ask. Thanks.

  • ASA5505 Novice. Setting up Outside/Inside/and DMZ as Guest Network

    - by GriffJ
    I need a little help in developing a config for our ASA5505. I'm an MCSA/MCITPAS but I don't have a lot of practical cisco experience. Here is what I need help with, we currently have a PIX as our boarder gateway and well it's antiquated and it only has a 50 user license which means I'm constantly clearing local-host throughout the day as people complain. I discovered that the last IT person bought at couple ASA5505s and they've been sitting in the back of a cupboard. So far I've duplicated the configuration from the pix to the asa but as I was going to be going this far I thought I'd go further and remove another old cisco router that was used only for the guest network, I know the asa can do both jobs. So I'm going to paste a scenario I wrote up with the actual IPs changed to protect the innocent. ... Outside Network: 1.2.3.10 255.255.255.248 (we have a /29) Inside Network: 10.10.36.0 255.255.252.0 DMZ Network: 192.168.15.0 255.255.255.0 Outside Network on e0/0 DMZ Network on e0/1 Inside Network on e0/2-7 DMZ Network has DHCPD Enabled. DMZ DHCPD Pool is 192.168.15.50-192.168.15.250 DMZ Network needs to be able to see DNS on Inside Network at 10.10.37.11 and 10.10.37.12 DMZ Network needs to be able to access webmail on inside network at 10.10.37.15 DMZ Network needs to be able to access business website on inside network at 10.10.37.17 DMZ Network needs to be able to access the outside network (access to the internet). Inside Network has NO DHCPD. (dhcp is handled by domain controller) Inside Network needs to be able to see anything on the DMZ network. Inside Network needs to be able to access the outside network (access to the internet). There is some access-list stuff already, some static mapping already. Maps external IPs from our ISP to our inside server IPs static (inside,outside) 1.2.3.11 10.10.37.15 netmask 255.255.255.255 static (inside,outside) 1.2.3.12 10.10.37.17 netmask 255.255.255.255 static (inside,outside) 1.2.3.13 10.10.37.20 netmask 255.255.255.255 Allows access to our Webserver/Mailserver/VPN from the Outside. access-list 108 permit tcp any host 1.2.3.11 eq https access-list 108 permit tcp any host 1.2.3.11 eq smtp access-list 108 permit tcp any host 1.2.3.11 eq 993 access-list 108 permit tcp any host 1.2.3.11 eq 465 access-list 108 permit tcp any host 1.2.3.12 eq www access-list 108 permit tcp any host 1.2.3.12 eq https access-list 108 permit tcp any host 1.2.3.13 eq pptp Here is all the NAT and route stuff I have so far. global (outside) 1 interface global (outside) 2 1.2.3.11-1.2.3.14 netmask 255.255.255.248 nat (inside) 1 0.0.0.0 0.0.0.0 nat (dmz) 1 0.0.0.0 0.0.0.0 route outside 0.0.0.0 0.0.0.0 1.2.3.9 1

  • I need to get VMWare Server running inside of a VMWare ESXi virtual machine

    - by Josh Moore
    Yes, I know running a virtual machine inside of a virtual machine is a bad idea. Yes, I know it will be very slow. However, our production system required VMs in VMWare server and I do not want to setup a real server for each of our developers for testing. I would like to be able to setup all of the VMWare servers (that mimic our production environment) on one ESXi server. I have found as much info as I can about this topic and I have tried what was suggested here and here. I have not been able to get any of these suggestions to work, I still get the VM cannot run inside of a VM error. If there are any other suggestions that anybody else have that would be great thanks.

  • Building NanoBSD inside a jail

    - by ptomli
    I'm trying to setup a jail to enable building a NanoBSD image. It's actually a jail on top of a NanoBSD install. The problem I have is that I'm unable to mount the md device in order to do the 'build image' part. Is it simply not possible to mount an md device inside a jail, or is there some other knob I need to twiddle? On the host /etc/rc.conf.local jail_enable="YES" jail_mount_enable="YES" jail_list="build" jail_set_hostname_allow="NO" jail_build_hostname="build.vm" jail_build_ip="192.168.0.100" jail_build_rootdir="/mnt/zpool0/jails/build/home" jail_build_devfs_enable="YES" jail_build_devfs_ruleset="devfsrules_jail_build" /etc/devfs.rules [devfsrules_jail_build=5] # nothing Inside the jail [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# sysctl security.jail security.jail.param.cpuset.id: 0 security.jail.param.host.hostid: 0 security.jail.param.host.hostuuid: 64 security.jail.param.host.domainname: 256 security.jail.param.host.hostname: 256 security.jail.param.children.max: 0 security.jail.param.children.cur: 0 security.jail.param.enforce_statfs: 0 security.jail.param.securelevel: 0 security.jail.param.path: 1024 security.jail.param.name: 256 security.jail.param.parent: 0 security.jail.param.jid: 0 security.jail.enforce_statfs: 1 security.jail.mount_allowed: 1 security.jail.chflags_allowed: 1 security.jail.allow_raw_sockets: 0 security.jail.sysvipc_allowed: 0 security.jail.socket_unixiproute_only: 1 security.jail.set_hostname_allowed: 0 security.jail.jail_max_af_ips: 255 security.jail.jailed: 1 [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# mdconfig -l md2 md0 md1 md0 and md1 are the ramdisks of the host. bsdlabel looks sensible [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# bsdlabel /dev/md2s1 # /dev/md2s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 1012016 16 4.2BSD 0 0 0 c: 1012032 0 unused 0 0 # "raw" part, don't edit newfs runs ok [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# newfs -U /dev/md2s1a /dev/md2s1a: 494.1MB (1012016 sectors) block size 16384, fragment size 2048 using 4 cylinder groups of 123.55MB, 7907 blks, 15872 inodes. with soft updates super-block backups (for fsck -b #) at: 160, 253184, 506208, 759232 mount fails [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# mount /dev/md2s1a _.mnt/ mount: /dev/md2s1a : Operation not permitted UPDATE: One of my colleagues pointed out There are some file systems types that can't be securely mounted within a jail no matter what, like UFS, MSDOFS, EXTFS, XFS, REISERFS, NTFS, etc. because the user mounting it has access to raw storage and can corrupt it in a way that it will panic entire system. From http://www.mail-archive.com/[email protected]/msg160389.html So it seems that the standard nanobsd.sh won't run inside a jail while it uses the md device to build the image. One potential solution I'll try is to chroot from the host into the build jail, rather than jexec a shell.

  • Connect to RDS inside a VPC using Opsworks located in another VPC

    - by Consuelo Merino
    I have a RDS instance (mysql) inside a VPC called vpc-a (10.0.0.0/16). This instance is private, it can only be accessed from vpc-a. We created a stack on opsworks inside another VPC called vpc-b (10.1.0.0). We want to connect opsworks to the RDS but it doesn't work. It refuses to connect. I tried adding said subnet to the RDS security group. Also read a lot of documentation but I haven't stumbled across the answer. Any help would be greatly appreciated.

  • Syncronization inside the same PC

    - by FGO
    Hi, I work in a company without a server and operating in diferent countries. Because of this we work on a virtual office basis and share files through a virtual server called Drop Box. I'm the controller of this virtual server and find it to be incomplete. We work on levels of permission so I invite access to users for 3 possible levels and find sometimes that I need to have a specific folder inside one mother folder to be inside 2 levels. The only way I can find to make my life easier is to automatically syncronize specific folders between diferent mother folders, but I don't know how to do this in windows 7. Can anyone give me a hint? Thanks

  • Running Coldfusion Commands inside an HTML File?

    - by KM01
    Hello, Is it possible to run CF commands inside an HTML file by updating Apache configs/htaccess file? When I searched online, I didn't come across any answers for CF, saw several posting for PHP (perhaps I am not searching for the right terms ... ?). Specifically, we have CF 6 (I know, don't say it) on Solaris, and Apache 2, and was thinking of using this line: AddType application/x-httpd-coldfusion .html so we can use cfinclude inside the HTML files, but this did not work. Your time, ideas and thoughts are much appreciated! KM

  • UINavigationController inside tabbar loading a child root view

    - by Doug
    Hi guys, Firstly i'll preface by saying that i am a complete Cocoa touch/objective c noob (.Net dev having a dabble) I have searched on Google as well as here but cannot seem to find an easy solution. I have a UItabbarcontroller view with a UINavigationController inside its first tab I have the root view for this UINavigationController stored in a seperate class and NIB as i am trying to seperate the data viewing from the data loading (i'm going to reuse the table list in multiple places in my database) and simply pass the root view its data using a loading method and have it take it from there. What i want to happen: App loads and loads the first view of the tab bar (A UINavigationController) The UINavigationController inside the first view loads a root view (a UIViewController with a table view) and sets its title The UINavigationController loads the data from a web service and parses it The UINavigationController sends the data to a loading method inside the UIViewController Am i thinking about this completely wrongly? What currently happens: the first tab bar loads with an empty uinavigationcontroller (no table view) the data methods fire and get the webservice data this child view gets sent its data using the loading method the tableview delegate events fail to fire inside the child view telling it to load the data into the table I just can't seem how to load my second view inside the root view of the navigation controller and then send it my data?

  • UINavigationController inside UINavigationController view issue

    - by HurkNburkS
    I have two navigationcontrollers a main one and a sub one. The sub one is displaying inside the main one, which I am also hiding its navigationbar. as a result I am having some weird issues (things inside the view are being pushed down exactly the height of the navigationbar i am hiding) with the stuff I am displaying on the inside of the sub navigationcontroller. it looks like this. The left view is what I am doing in interface builder and the resulting view in the simulator. any help would be greatly appreciated. UPDATE: Here is the view with the subnav bar turned on so you can see the structure of my view. and here is the same view with the subnav turned off... can you see how the A is still sitting lower than it should be.. wel I think its because of the main navbar now as the whole subnavbar sits inside this view.. Last update that shows whats missing from the view

  • Throwing a C++ exception from inside a Linux Signal handler

    - by SoapBox
    As a thought experiment more than anything I am trying to get a C++ exception thrown "from" a linux signal handler for SIGSEGV. (I'm aware this is not a solution to any real world SIGSEGV and should never actually be done, but I thought I would try it out after being asked about it, and now I can't get it out of my head until I figure out how to do it.) Below is the closest I have come, but instead of the signal being caught properly, terminate() is being called as if no try/catch block is available. Anyone know why? Or know a way I can actually get a C++ exception from a signal handler? The code (beware, the self modifying asm limits this to running on x86_64 if you're trying to test it): #include <iostream> #include <stdexcept> #include <signal.h> #include <stdint.h> #include <errno.h> #include <string.h> #include <sys/mman.h> using namespace std; uint64_t oldaddr = 0; void thrower() { cout << "Inside thrower" << endl; throw std::runtime_error("SIGSEGV"); } void segv_handler(int sig, siginfo_t *info, void *pctx) { ucontext_t *context = (ucontext_t *)pctx; cout << "Inside SIGSEGV handler" << endl; oldaddr = context->uc_mcontext.gregs[REG_RIP]; uint32_t pageSize = (uint32_t)sysconf(_SC_PAGESIZE); uint64_t bottomOfOldPage = (oldaddr/pageSize) * pageSize; mprotect((void*)bottomOfOldPage, pageSize*2, PROT_READ|PROT_WRITE|PROT_EXEC); // 48 B8 xx xx xx xx xx xx xx xx = mov rax, xxxx *((uint8_t*)(oldaddr+0)) = 0x48; *((uint8_t*)(oldaddr+1)) = 0xB8; *((int64_t*)(oldaddr+2)) = (int64_t)thrower; // FF E0 = jmp rax *((uint8_t*)(oldaddr+10)) = 0xFF; *((uint8_t*)(oldaddr+11)) = 0xE0; } void func() { try { *(uint32_t*)0x1234 = 123456789; } catch (...) { cout << "caught inside func" << endl; throw; } } int main() { cout << "Top of main" << endl; struct sigaction action, old_action; action.sa_sigaction = segv_handler; sigemptyset(&action.sa_mask); action.sa_flags = SA_SIGINFO | SA_RESTART | SA_NODEFER; if (sigaction(SIGSEGV, &action, &old_action)<0) cerr << "Error setting handler : " << strerror(errno) << endl; try { func(); } catch (std::exception &e) { cout << "Caught : " << e.what() << endl; } cout << "Bottom of main" << endl << endl; } The actual output: Top of main Inside SIGSEGV handler Inside thrower terminate called after throwing an instance of 'std::runtime_error' what(): SIGSEGV Aborted Expected output: Top of main Inside thrower caught inside func Caught : SIGSEGV Bottom of main

  • Retrieve property from classpath inside POM

    - by Jeroen
    For my current project I want to integrate a maven plug-in for database migrations. For this plug-in to work, however, I have to obtain the database settings inside my POM. My database settings are currently placed inside a hibernate.properties file, positioned in a directory that is marked as maven resource. For a variety of reasons I do not want to duplicate my database configurations in both the pom and hibernate.properties. I'm aware that maven offers a "filtering" ability which makes it possible to specify the database settings as property inside my POM, and reference them inside my hibernate.properties as ${property_name}. But as I'm using multiple maven profiles, with different property resources, this is not a suitable solution. Instead I'd like my database configurations to be loaded from a property file inside my classpath (e.g. classpath:hibernate.properties), and use these properties in my migration plug-in configuration. I have already tried the org.codehaus.mojo » properties-maven-plugin, but this plug-in only accepts absolute locations. Is there a plug-in which can scan all my maven resources for a certain property?

  • codemirror fails when adding </textarea> tag inside it

    - by Jorre
    I'm using codemirror http://marijn.haverbeke.nl/codemirror/ to let users create their own web templates inside a web application. Codemirror works great, except for the time that users have put a tag inside their source code. When I load that up inside code mirror, it breaks everything in the source code that follows after because it thinks my codemirror text area is closed. I'm using the following way to launch codemirror: CodeMirror.fromTextArea('code') It works great on my existing textarea "code" except when users add inside their templates (in the codemirror textarea). Any help is much appreciated!

  • Count total children divs inside a container

    - by kuswantin
    I want to count the total divs inside a container and toggle their visibilities with structure like this. Please also note that the div.content may also reside inside another nested or even nested-nested containers. That's why I handle it with jquery to add div.topmost for each topmost parent container: <div id="parent"> <div class="counter">There are 3 div.contents inside the container below</div> <div class="container"> <div class="content"> 1 </div> <div class="container"> <!--container inside container --> <div class="content"> 2 </div> <div class="content"> 3 </div> </div> </div> <div class="counter">There are 5 div.contents inside the container below</div> <div class="container"> <div class="content"> 1 </div> <div class="content"> 2 </div> <div class="content"> 3 </div> <div class="content"> 4 </div> <div class="content"> 5 </div> </div> </div> And the jquery: // only grab the top most container $('#parent > .container').addClass('topmost'); var topMost = $(".topmost"); var totContent = topMost.children('.content').size(); if (topMost.length > 0) { topMost.before('<div class="toggle">There are ' + totContent + ' div.contents inside the container below</div>'); } topMost.hide(); $('#parent > .counter').click(function() { $(this).next('.topmost').toggle(); //alert(totContent); return false; }); But I can't make it work to loop for each div.counter. The counter always shows all div.content. So placing the each function is suspected to be the problem. Any hep would be very much appreciated. Thanks

  • jsTree: Prevent before and after TYPE, only use inside

    - by Nic Hubbard
    I am using jsTree which is very nice. When dragging and dropping, I don't really care for the before and after types, I only want to use inside. Meaning, I am only concerned about that parent that a child is dropped into, rather than where the order is with other elements INSIDE the parent. So, I wanted to build my callback, so it always refers to the parent node that it is inside. But, it is not fool proof, yet. onmove : function (NODE,REF_NODE,TYPE,TREE_OBJ,RB) { if (TYPE == 'inside') { alert('Item to move:'+$(NODE).attr('rel')+' to '+$(REF_NODE).attr('rel')+' '+TYPE); } else if (TYPE == 'after') { alert('Item to move:'+$(NODE).attr('rel')+' to '+$(REF_NODE).parent().parent('li').attr('rel')+' '+TYPE); } }, Does anyone have suggestions, how I can change my callback, so that the REF_NODE is always the parent that the NODE is moved into? Rather than a sibling of, which is a child of the parent?

  • Find order of data inside an array

    - by user271619
    I have a simple array of stuff: $array = array("apples","oranges","strawberries"); I am trying to find the order of the stuff inside the array. (sometimes the order changes, and so do the items) I'm expecting to get something like this: "apples" = 0, "oranges = 1, "strawberries = 2 The end result has something to do with database sorting. Something like this, inside a foreach loop: UPDATE tbl SET sortorder = $neworder WHERE fruit = '$fruitname' The $neworder variable would be populated with the new order, inside the array. While the $fruit variable comes from the item inside the array.

  • jQuery display text nested in paragraphs inside a div

    - by user961627
    I have HTML that looks something like this: <div class='textbox' data-title='Sometitle'> <div class='textareaedit'> <p><strong>Test sample text</strong></p> </div> </div> I'm sometimes going to have a few different <p> tags inside the textareaedit divs, and sometimes strong tags around the text inside the <p> (as in this example), and sometimes a span tag, and sometimes it's going to be without further tags inside the <p>. I want to iterate through each textbox on my page, grab its title and also the text nested inside <p> tags in textareaedit. I'm giving the output via console for testing. This is my jQuery code, but I get no output for the second console.log() line: $('.textbox').each(function() { $this = $(this); console.log($this.attr('data-title')+ ":\n"); $this.children('textareadit').children('p').each(function(){ console.log($(this).html()); // not giving any output, it's blank }); }); I tried $(this).text() as well, but no difference. You may think this example has the sample text inside <strong> tags within the <p>, but I've also tried the same example without the strong, where the text was the direct child of <p>, but it didn't make a difference. How can I capture the text?

  • Using Django view variables inside templates

    - by William
    Hi, this is a rather basic question (I'm new to Django) but I'm having trouble using a variable set in my view inside my template. If I initialize a string or list inside my view (i.e. h = "hello") and then attempt to call it inside a template: {{ h }} there is neither output nor errors. Similarly, if I try to use a variable inside my template that doesn't exist: {{ asdfdsadf }} there is again no error reported. Is this normal? And how can I use my variables within my templates. Thanks!
