• em1: watchdog timeout -- resetting virtualbox

  - by lightmanhk

  everyone. I try to configure network adapter of my freebsd on virtualbox machine. At first setting up, I got it right. However, after a couple of reboots, my VM gives me a error message: says "em1:Watchdog timeout -- resetting" I tried to google it, and there is no solution that works for me. The following is my network adapter of my VM: Apapter1: NAT Adapter2: Host-only Adapter vboxnet0 On my Virtualbox setting: Host-only networks: Adapter: IPv4 address: 192.168.56.10 IPv4 network mask: 255.255.255.0 On my FreeBSD VM /etc/rc.conf ifconfig_em0="DHCP" ifconfig_em1="inet 192.168.56.11 netmask 255.255.255.0" Moreover, strange thing is that, for example, if timeout error message show at ttyv0 , when I log in at different ttyv[1-9], the error message will not be shown. but in ttyv0, it still gives me the message. And, in term of functionality of em1, it does work. I have no clue about this problem. Hoping any one can give me a solution or suggestion. That will be great! Thanks a lot. Freebsd version: 9.0-RELEASE FreeBSD 9.0-RELEASE i386 Virtual box: 4.1.2 r73507

• (HTML) PNG on top of another PNG - possible to eliminate full transparency?

  - by MHTri

  I'd like to put a logo png onto of another coloured png. They both have transparent backgrounds. When I try this the images blend together. Curiously, in Photoshop the logo retains its opaque-ness - I put colours on the layers underneath it, another image, etc etc, the logo is still opaque. I'd like to do it this way so I can rotate the background images. How do I fix this? [edit]I've cooked up an example image: http://i.imgur.com/XtoGn.png The left is what I want to happen, the right is what happens on all browsers (I know the background isn't transparent but bear with me - they're both transparent pngs, with the background having a gradient layer mask). I've put the images like this <div> <img id="backgroundImg" style="position: absolute; top: 0;" src="/Images/background.png" /> <img id="logoImg" src="/Images/logo.png" /> </div> I'm not entirely sure what blending mode I'm using in PS.

• Collision Detection (Ground & Slopes) in 2D Platform Game using Pygame Rects

  - by RedCap

  Hi, First off, I am not after any instructions on logic for collision detection; I get it. What I am trying to work out is the least complicated way to do this with Pygame using Sprites & Rects. I want to be able to check collisions for the Player against ground, walls & slopes. In theory it is quite straight forward, but I'm having difficulty because it seems like you cannot do this with one Rect. One Rect is simple enough to get you collisions in the X plane against walls. The same Rect could be used also be used in the Y plane against solids, but not with slopes - since with the collision routines in Pygame it checks the whole Rect (or mask), rather than perhaps just the bottom middle of the Rect. It seems in addition you need to have a number of "sprites" to check collisions with, that are 1x1 pixel in various places around the Player. What's the easiest way to do this, without having a bunch of 3, 4, or more separate "collision pixels" to check against slopes? Geoff

• Fade in an HTML element with raw javascript over 500 miliseconds.

  - by Juan C. Rois

  Hello everybody, Once again I find myself stuck by something that I just don't understand. Any help would be appreciated. I'm working on a modal window, you click something and the background is masked and a modal window shows some content. I have a div with "display:none" and "opacity:0", and when the user triggers the modal, this div will overlay everything and have certain transparency to it. In my mind, what I need to do is: Set the opacity Perform a "for" loop that will check if the opacity is less than the desired value. Inside this loop, perform a "setInterval" to gradually increment the value of the opacity until it reaches the desired value. When the desired value has been reached, perform an "if" statement to "clearInterval". My code so far is as follows: var showMask = document.getElementById('mask'); function fireModal(){ showMask.style.opacity = 0; showMask.style.display = 'block'; var getCurrentOpacity = showMask.style.opacity; var increaseOpacity = 0.02; var finalOpacity = 0.7; var intervalIncrement = 20; var timeLapse = 500; function fadeIn(){ for(var i = getCurrentOpacity; i < finalOpacity; i++){ setInterval(function(){ showMask.style.opacity = i; }, intervalIncrement) } if(getCurrentOpacity == finalOpacity){ clearInterval(); } } fadeIn(); } As you all can guess, this is not working, all it does is set the opacity to "1" without gradually fade it in. Thanks in advance for your help.

• How can I define an irregular area of the screen and find the closest point to the mouse in that area?

  - by JonathonG

  I'm looking for a method to define an area of the screen that the mouse cannot leave. I have been directed by rob mayoff, the answerer of this question, that I can use a Quartz Event Tap to detect mouse events. This puts me part of the way to the solution to THIS question. I need to define an irregular area of the screen, not just a rectangle, that the mouse cannot leave. I have been researching this and the only idea I can come up with is using a bitmap to define the irregular area, as it will be very oddly shaped. However, I am open to solutions other than using a bitmap. Since this must be done on a Mac, I've determined that I will have to use objective C / Cocoa . I need to know how to define the area and, equally importantly, how to find the closest point in the area to the mouse (so that I can move the mouse to it if the mouse tries to move outside of the area). This is similar to what the restricted area will look like: [edit:] Okay, I've come up with part of the answer to this. If I can do a basic (light-weight) point collision detection on the image mask, I can use a simple algorithm to detect the closest point to the mouse on the black area of the image. I could do this by calculating distance between a pre-defined point (P) inside the black area of the image and the target mouse position (T), taking the midpoint (M), then checking if the midpoint is inside or outside of the shape (black or white, respectively). If M is inside the shape, then move the P to M, otherwise move T to the M, continuously recalculate this until the distance between T and P is 1 pixel or less, then move the mouse to the final calculated position. All of that being said, I still need some way to test the position of the mouse against that same position on the bitmap (assume the bitmap is the same resolution as the monitor), and check if that point is black or white. All of this needs to be done in the background, without this application actually having focus, or the bitmap being visible... is this possible?

• AS3 colorTransform over multiple frames?

  - by user359519

  (Flash Professional, AS3) I'm working on a custom avatar system where you can select various festures and colors. For example, I have 10 hairstyles, and a colorPicker to change the color. mc_myAvatar has 10 frames. Each frame has a movieclip of a different hairstyle (HairStyle1, HairStyle2, etc.) Here's my code: var hairColor:ColorTransform; hairColor = mc_myAvatar.hair.colorLayer.transform.colorTransform; hairColor.color = 0xCCCC00; mc_myAvatar.hair.colorLayer.transform.colorTransform = hairColor; This correctly changes the initial color. I have a "nextHair" button to advance mc_myAvatar.hair to the next frame. When I click the button, I get an error message saying that I have a null object reference. I added a trace, and mc_myAvatar.hair.colorLayer is null on frame 2. Why??? I've clearly named HairStyle2 as "colorLayer" in frame 2. I think the problem is related to me using the same name for different classes/movieclips, but I don't know how to fix the problem... I added a square movieclip below my hairStyle movieclips, named the square "colorLevel", and deleted the name from my hairStyle clips. When I click the next button, the square correctly maintains the color from frame to frame. However, having a square doesn't do me much good. :( I tried converting the hairStyle layer to a mask. Doing this, however, results in yet another "null object" error - mc_myAvatar.hair.colorLayer is null after frame 1. I even tried "spanning" my colorLevel across all frames (no keyframes), thinking that this would give me just one movieclip to work with. No luck. Same error! What's going on, here? Why am I getting these null objects, when they are clearly defined in my movieclip? I'm also open to suggestions on a better way to do multiple frames and colors.

• MVC design pattern in complex iPad app: is one fat controller acceptable?

  - by nutsmuggler

  I am building a complex iPad application; think of it as a scrapbook. For the purpose of this question, let's consider a page with two images over it. My main view displays my doc data rendered as a single UIImage; this because I need to do some global manipulation over them. This is my DisplayView. When editing I need to instantiate an EditorView with my two images as subviews; this way I can interact with a single image, (rotate it, scale it, move it). When editing is triggered, I hide my DisplayView and show my EditorView. In a iPhone app, I'd associate each main view (that is, a view filling the screen) to a view controller. The problem is here there is just one view controller; I've considered passing the EditorView via a modal view controller, but it's not an option (there a complex layout with a mask covering everything and palettes over it; rebuilding it in the EditorView would create duplicate code). Presently the EditorView incorporates some logic (loads data from the model, invokes some subviews for fine editing, saves data back to the model); EditorView subviews also incorporate some logic (I manipulate images and pass them back to the main EditorView). I feel this logic belongs more to a controller. On the other hand, I am not sure making my only view controller so fat a good idea. What is the best, cocoa-ish implementation of such a class structure? Feel free to ask for clarifications. Cheers.

• Rotating bits of any integer in C

  - by Tim

  Pass a integer 2 to this function and then return a integer which is 4 x = 2; x = rotateInt('L', x, 1); (left shift the bits by 1) Example: 00000010 - rotate left by 1 - 00000100 but if I pass this: x = rotateInt('R', x, 3); it will return 64, 01000000 Here is the code, can someone correct the error... thanks int rotateInt(char direction, unsigned int x, int y) { unsigned int mask = 0; int num = 0, result = 0; int i; for(i = 0; i < y; i++) { if(direction == 'R') { if((x & 1) == 1) x = (x ^ 129); else x = x >> 1; } else if(direction == 'L') { if((x & 128) == 1) x = (x ^ 129); else x = x << 1; } } result = (result ^ x); return result; }

  - by fxg

  I´m working on a wordpress template. I´m trying to load the single.php of a post using ajax.

• Linux Mint 10 LXDE computer to act as LTSP Server without luck

• DHCP "no answer" on CentOS 6.4

  - by Kev

  I installed a DHCP server (yum install dhcp) and this is my conf: # create new # specify domain name option domain-name "mydomain.name"; # specify DNS's hostname or IP address option domain-name-servers 10.0.1.1, 10.0.1.2; option ntp-servers 10.0.1.1, 10.0.1.2; allow unknown-clients; # default lease time default-lease-time 2628000; # max lease time max-lease-time 2628000; # about a month # this DHCP server to be declared valid authoritative; # specify network address and subnet mask subnet 10.0.0.0 netmask 255.0.0.0 { # specify the range of lease IP address range dynamic-bootp 10.0.2.1 10.0.2.50; # specify broadcast address option broadcast-address 10.255.255.255; # specify default gateway option routers 10.0.0.1; allow unknown-clients; } service dhcp start reports [ OK ]. Yet, if I disable my other DHCP server (Win2k3) and get a client to try renewing its IP lease, it times out. So I installed dhcping. No matter what options I try, including directing dhcping at my server, adding a client address in the range, adding my hardware address, it replies 'no answer'. I'm also trying -i since that seems to be more akin to what a WinXP client would try to do, based on /var/log/messages. It logs the attempts (from dhcping here) as: Oct 24 18:55:13 newdc dhcpd: DHCPINFORM from 10.0.2.15 via eth0:4 Oct 24 18:55:13 newdc dhcpd: DHCPACK to 10.0.2.15 (00:11:25:66:4e:7f) via eth0:4 Oct 24 18:55:13 newdc dhcpd: DHCPINFORM from 10.0.2.15 via eth0:3 Oct 24 18:55:13 newdc dhcpd: DHCPACK to 10.0.2.15 (00:11:25:66:4e:7f) via eth0:3 Oct 24 18:55:13 newdc dhcpd: DHCPINFORM from 10.0.2.15 via eth0 Oct 24 18:55:13 newdc dhcpd: DHCPACK to 10.0.2.15 (00:11:25:66:4e:7f) via eth0 The :3 and :4 are because I have a few extra Host(A) records for this server so it responds on more than one IP for our intranet app. No answer? It sounds like it should be getting three answers...no? (And if that's the problem, how do I limit the DHCP service to replying from eth0?)

• How to set up a mini call center?

  - by Ralph

  I'm trying to figure out how to set up a miniature call center for a small business. Like, for 1-4 people to take calls, but hopefully expandable to more. We want to accept nation-wide calls, and then I guess distribute the calls among the available agents. If no one is available, I guess it should either put them in a queue and play some annoying music for them, or forward to call to an agent who has least-recently taken a call who can then quickly answer and say "please hold" until they're done their call. We want to have one phone number that customers can call. I guess we then need some kind of ACD system which would take each call and forward it to an agent based on some algorithm? Then we would need to purchase a separate phone line for each agent, plus one just for the distributor? Or do we need several "extra" lines to maintain a queue (one for each customer waiting too)? This "ACD" thing, is it just a device that you would plug a phone line into (or several?), and maybe connect to a computer, aided by some software? Or is a subscription thing that I would need from my local telephone provider? Next, the business we're running, the callers will be repeat customers. It would be helpful to automatically pull up their profile based on the incoming number. The "software" our agents will be running will just be a website where they can log in (preferably from home) and then enter some information they would obtain through the call. So, the system would have to somehow interface with the website if possible. If not, we'll just have to ask each customer for an identifier (phone number, username, customer number, or something). Is this possible? I guess each computer would need a device that the call would pass through, and then if I can somehow hook into that, then I can write some software that will interface with the site. So, where do I start? What hardware do we need to buy? What subscriptions do we need? We were thinking this magicJack might help us in accepting long-distance calls for cheaper, but my understanding is that they provide you with some weird-looking number, is there a way we could "mask" it with our toll-free number? And then pass the incoming calls through the distributor system, which would then get passed to the call-accepting device which would both allow an agent to answer the call and have a software hook? (I realize this might be partially out of the scope of SU, but I wasn't sure where else to ask. It is about computer(-aided) hardware and software anyway.) P.S.: I don't need any of that "press 1 to talk to..." or "say xyz to..." junk. Just a straight-forward, connect-to-next-available-agent system.

I have just set up a new VM Workstation (7) on a W2K8 64bit server (I'll be converting to ESXI 4 once I can find a decent book on it, so for the meanwhile I use workstation). I have imported a number of VM's and setup some new ones on the server.In short the problem with some of the VM's being unable to reach the Internet is that they can't reach the gateway. I've looking at a number of things and can pretty safely rule out the following: Switch, Router, DHCP Server, DNS, Client IP configuration, Routes and typos. The problem is that some of the new clients cannot reach the gateway if their IP address is hardcoded, they can't even ping it by IP address. That rules out DNS and DHCP. Now, if I allow them to get their IP address by DHCP they can reach the gateway and Internet without issue. The interesting thing on this, is that this behavior occurs even if I leave the DNS information hardcoded under TCP/IP settings. It doesn't work unless the IP and gateway are handed out by DHCP even though the same information IP info is being used by the host. Fundamentally from the standpoint of the clients, they are trying to reach the exact same gateway using the exact same IP information regardless of whether they are hardcoded or assigned by DHCP. Here's an example of one client. IP Address 192.168.7.66 - Subnet Mask 255.255.255.0 - Gateway 192.168.7.254 - DNS1 192.168.7.44 - DNS2 192.168.7.254. The issue occurs across six different microsoft operating systems, Windows 7 and Windows 2008 variants all have the issue. My W2K3, XP, Vista and W98 clients all work without issue with hardcoded IP addresses. I have tried things like rearranging the DNS order, flushing DNS and so on. It's not a routing or switch issue as the clients can work just fine if they get their IP by DHCP. It's not a paramater issue as the exact same paramaters are handed out by DHCP as I plug in by hand. It's not a DNS issue as clients cant reach other clients even with IP addresses only. I have run a tracert to the gateway by IP address and it times out on the very first hop before failing on hop3 with destination host unreachable. If I get the IP address by DHCP the tracert finds the gateway (and Internet) without issue. I have read a few other posts online in forums talking about this problem randomly occuring over the years in other VM versions as well, so I suspect some kind of long standing bug. Does anyone have any ideas on this? Is it possibly a bug with Windows 7 and W2K clients under VM?

• APC (PHP Cache) Uptime 0 minutes, not caching

  - by Jussi

  My goal is to implement APC for opcode cache for a drupal 6 production site. I have so far tested APC with several php files with and without including other php files with include_once. Also tried to tweak the apc.ini values for shm_size, apc.include_once_override and apc.stat. Restarted apache every time. Resulting in apc.php not showing any changes in any values. (except of course the changed apc.ini values are shown as they should) Every time i refresh the apc.php test page, the start time resets as the current time showing uptime 0 minutes. apc.php -testpage shows: General Cache InformationAPC Version 3.1.9 PHP Version 5.2.10 APC Host xxxx.xx.xx Server Software Apache/2.2.3 (CentOS) Shared Memory 1 Segment(s) with 128.0 MBytes (mmap memory, pthread mutex Locks locking) Start Time 2011/07/26 11:53:56 Uptime 0 minutes File Upload Support 1 Cached Files 0 ( 0.0 Bytes) Hits 1 Misses 1 Request Rate (hits, misses) 2.00 cache requests/second Hit Rate 1.00 cache requests/second Miss Rate 1.00 cache requests/second Insert Rate 0.00 cache requests/second Cache full count 0 Cached Variables 0 ( 0.0 Bytes) Hits 0 Misses 0 Request Rate (hits, misses) 0.00 cache requests/second Hit Rate 0.00 cache requests/second Miss Rate 0.00 cache requests/second Insert Rate 0.00 cache requests/second Cache full count 0 apc.cache_by_default 1 apc.canonicalize 1 apc.coredump_unmap 0 apc.enable_cli 0 apc.enabled 1 apc.file_md5 0 apc.file_update_protection 2 apc.filters apc.gc_ttl 3600 apc.include_once_override 0 apc.lazy_classes 0 apc.lazy_functions 0 apc.max_file_size 16 apc.mmap_file_mask /tmp/apcphp5.095eRm apc.num_files_hint 1024 apc.preload_path apc.report_autofilter 0 apc.rfc1867 0 apc.rfc1867_freq 0 apc.rfc1867_name APC_UPLOAD_PROGRESS apc.rfc1867_prefix upload_ apc.rfc1867_ttl 3600 apc.serializer default apc.shm_segments 1 apc.shm_size 128M apc.slam_defense 0 apc.stat 0 apc.stat_ctime 0 apc.ttl 7200 apc.use_request_time 1 apc.user_entries_hint 4096 apc.user_ttl 7200 apc.write_lock 1 Host Status Diagrams: Free: 128.0 MBytes (100.0%) Hits: 1 (50.0%) Used: 20.3 KBytes (0.0%) Misses: 1 (50.0%) Detailed Memory Usage and Fragmentation: Fragmentation: 0% phpinfo shows: Server API CGI/FastCGI APC: Version 3.1.9 APC Debugging Enabled MMAP Support Enabled MMAP File Mask /tmp/apcphp5.JkKDk7 Locking type pthread mutex Locks Serialization Support php Revision $Revision: 308812 $ Build Date Jul 21 2011 14:31:12 I followed these steps to find if suexec settings would prevent caching: http://www.litespeedtech.com/support/forum/showthread.php?t=4189 [root@host /]# ps -ef|grep lsphp root 20402 17833 0 11:21 pts/0 00:00:00 grep lsphp [root@host /]# ps -waux root 17833 0.0 0.1 5004 1484 pts/0 S 10:39 0:00 bash ..indicates that there is no lsphp running on the host also I read the following article and comments, concluding that in my case the problem is not the suexec as the user apache is the httpd process owner http://www.brandonturner.net/blog/2009/07/fastcgi_with_php_opcode_cache/ also suexec command is not recognized when logged and launced as root @ host also i'm almost confident that there is no cPanel running on the host to check if a setting there would reset the running cache process at some interval This leaves me with few clues where to head next. I tried to set (with chown and chgrp) apache as the owner of the apc.php file and some test php files resulting in 500 server error. Is there a way to check if the file permissions prevent the apc stay running? I'm tremendously grateful for any suggestions or help.

• dnsmasq acts as the DHCP server for selected nodes overriding the existing DHCP server on the same LAN?

  - by user183394

  I am trying to set up a small "lab" at home. Like many modern homes, I have a regular DSL service which comes with a 2Wire 3600HGV router, which acts also as a DHCP server. Since I would like to PXE boot a few computers in my "lab" The 2Wire is inflexible to adjustments that I want to do I have used dnsmasq at work so I would like to use dnsmasq as the DHCP server for the few nodes in my "lab" if feasible. In the dnsmasq man page, there is the following: [...] -K, --dhcp-authoritative (IPv4 only) Should be set when dnsmasq is definitely the only DHCP server on a network. It changes the behaviour from strict RFC compliance so that DHCP requests on unknown leases from unknown hosts are not ignored. This allows new hosts to get a lease without a tedious timeout under all circumstances. It also allows dnsmasq to rebuild its lease database without each client needing to reacquire a lease, if the database is lost. [...] As far as I know, the ISC DHCP server can use the following to do what I would like to accomplish: authoritative; [...] subnet 192.168.1.0 netmask 255.255.255.0 { host nb0 { # only give DHCP information to this computer: hardware ethernet e8:9a:8f:17:70:42; fixed-address 192.168.1.10; option subnet-mask 255.255.255.0; option routers 192.168.1.254; option domain-name-servers 192.168.1.254; # Non-essential DHCP options filename "/pxelinux.0"; } [...] But I much prefer dnsmasq's "all-in-one-ness". My question: do I have to couple the -K option with something else? As shown in the example above, the ISC DHCP server requires the mac addresses of managed nodes to be explicitly specified. Does dnsmasq have something similar? FYI, the machine on which I plan to run dnsmasq runs CentOS 6.3 64bit. It has a statically assigned IP address: 192.168.1.3.

• getfacl command and Linux file permissions - getting 403 error when accessing Wordpress

  - by tommytwoeyes

  I'm configuring Wordpress for a friend, and I just screwed up the Wordpress directory permissions (I suspect) using setfacl. Webfaction doesn't allow sudo or allow me to change the directory group ownership using chown. Now it appears that something I did is causing the entire application to give me 403 errors when I try to access it. The current directory listing looks like this (I set the whole thing to 777 temporarily to try to recover access to it): drwxrwsr-x+ 6 myusername myusername 4096 Mar 2 07:07 ./ drwxr-xr-x 3 root root 4096 Feb 25 19:48 ../ -rwxrwxr-x+ 1 myusername myusername 286 Mar 2 06:33 gzip.php -rwxrwxr-x+ 1 myusername myusername 4831 Mar 4 20:02 .htaccess -rwxrwxr-x+ 1 myusername myusername 397 Feb 25 19:49 index.php -rw-rw-r--+ 1 myusername myusername 15606 Feb 25 19:49 license.txt -rw-rw-r--+ 1 myusername myusername 9200 Feb 25 19:49 readme.html drwxrwsr-x+ 6 myusername myusername 4096 Feb 25 19:49 .svn/ -rwxrwxr-x+ 1 myusername myusername 4337 Feb 25 19:49 wp-activate.php drwxr-xr-x+ 10 myusername myusername 4096 Mar 4 20:03 wp-admin/ -rwxrwxr-x+ 1 myusername myusername 40283 Feb 25 19:49 wp-app.php -rwxrwxr-x+ 1 myusername myusername 226 Feb 25 19:49 wp-atom.php -rwxrwxr-x+ 1 myusername myusername 274 Feb 25 19:49 wp-blog-header.php -rwxrwxr-x+ 1 myusername myusername 3931 Feb 25 19:49 wp-comments-post.php -rwxrwxr-x+ 1 myusername myusername 244 Feb 25 19:49 wp-commentsrss2.php -rwxrwxr-x+ 1 myusername myusername 3485 Feb 25 20:15 wp-config.php drwxr-xr-x+ 6 myusername myusername 4096 Feb 26 08:52 wp-content/ -rwxrwxr-x+ 1 myusername myusername 1255 Feb 25 19:49 wp-cron.php -rwxrwxr-x+ 1 myusername myusername 246 Feb 25 19:49 wp-feed.php drwxrwxr-x+ 9 myusername myusername 4096 Feb 25 19:49 wp-includes/ -rwxrwxr-x+ 1 myusername myusername 1997 Feb 25 19:49 wp-links-opml.php -rwxrwxr-x+ 1 myusername myusername 2453 Feb 25 19:49 wp-load.php -rwxrwxr-x+ 1 myusername myusername 27787 Feb 25 19:49 wp-login.php -rwxrwxr-x+ 1 myusername myusername 7774 Feb 25 19:49 wp-mail.php -rwxrwxr-x+ 1 myusername myusername 494 Feb 25 19:49 wp-pass.php -rwxrwxr-x+ 1 myusername myusername 224 Feb 25 19:49 wp-rdf.php -rwxrwxr-x+ 1 myusername myusername 334 Feb 25 19:49 wp-register.php -rwxrwxr-x+ 1 myusername myusername 226 Feb 25 19:49 wp-rss2.php -rwxrwxr-x+ 1 myusername myusername 224 Feb 25 19:49 wp-rss.php -rwxrwxr-x+ 1 myusername myusername 9655 Feb 25 19:49 wp-settings.php -rwxrwxr-x+ 1 myusername myusername 18644 Feb 25 19:49 wp-signup.php -rwxrwxr-x+ 1 myusername myusername 3702 Feb 25 19:49 wp-trackback.php -rwxrwxr-x+ 1 myusername myusername 3210 Feb 25 19:49 xmlrpc.php The getfacl output looks like this: # file: . # owner: myusername # group: myusername user::rwx group::r-x group:apache:rw- mask::rwx other::r-x I simply wanted to change the ownership to myusername:apache and the file permissions to 755.

• Unable to ping local machines by name in Windows 7

  - by aardvarkk

  I'm having a strange (and persistent!) problem with pinging local machines on my network by name. I believe my machine (Windows 7 64-bit) is the only one having this issue. This is over a wireless connection. As an example, consider a device on my network by the name of WDTVLiveHub. It's a Western Digital Live Hub (surprise!). If I go to my router's DHCP Client Table in the browser (my router is a WRT400N), I see this entry: WDTVLiveHub 192.168.1.101 Great. So I try to ping that IP address: ping 192.168.1.101 Pinging 192.168.1.101 with 32 bytes of data: Reply from 192.168.1.101: bytes=32 time=9ms TTL=64 Reply from 192.168.1.101: bytes=32 time=16ms TTL=64 Reply from 192.168.1.101: bytes=32 time=16ms TTL=64 Reply from 192.168.1.101: bytes=32 time=16ms TTL=64 Ping statistics for 192.168.1.101: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 9ms, Maximum = 16ms, Average = 14ms OK, still looking good. Now I try to ping it by name: ping WDTVLiveHub Ping request could not find host WDTVLiveHub. Please check the name and try again. From what I've read, this implies a problem with DNS servers and host name lookups. Interestingly, if I type the following: pathping 192.168.1.101 I get this output: Tracing route to WDTVLIVEHUB [192.168.1.101] over a maximum of 30 hops: 0 Scotty [192.168.1.103] 1 WDTVLIVEHUB [192.168.1.101] Computing statistics for 25 seconds...

Scotty is obviously the name of my local machine. So it's able to find the name somehow when I do that approach... ipconfig /all shows the following under DNS servers: DNS Servers . . . . . . . . . . . : 192.168.1.1 ***.***.***.*** ***.***.***.*** Where the * represents the same DNS servers that show up in my router under DNS 1 and DNS 2 through the Internet.

The biggest problem is that my mapped network drives have to be done by IP, and then any time the router assigns new IP addresses to those devices, all of my network shares break again. Stinks! Would love some assistance on possible solutions. I've tried all of this netsh catalog resetting and that didn't seem to fix anything at all. Would love an explanation of what's going wrong, too, rather than blindly resetting things! Thanks!

• custom route not working on windows

  - by Michael Closson

  My windows laptop is directly connected to 192.168.1.0/24 (wireless lan). I access 10.21.0.0/16 though a router that is connected to both networks. The routing works fine with this configuration. I have a VPN, that connects to 10.0.0.0/8. The VPN network doesn't actually use any IPs in the 10.21.0.0/16 range. So I should be able to configure my routing table to route all the 10.21.0.0/16 IPs through the wireless lan, and all other 10.0.0.0/8 through the VPN. My understanding is that I can do this if the metric for the 10.21.0.0 is lower than that of the 10.0.0.0. The VPN (10.0.0.0) is automatically assigned metric 20. I have manually assigned the WLAN a metric of 1. I manually add an entry to the routing table with this command: route add 10.21.0.0 mask 255.255.0.0 192.168.1.201 metric 1 The route is then assigned a metric of 2 (which is expected). The problem is that it doesn't work. I can't ping any machine on the 10.21.0.0 network. But I can access other stuff on the 10.0.0.0. I can also access stuff on the 192.168.1.0. To debug this i've done the following. Run tcpdump on the router (192.168.1.201). I can verify that no packets for 10.21.0.0 arrive on that interface. Disable iptables on the router. Disable the windows firewall. Run wireshark on my laptop, to try and see which interface the ping requests go to. But I can't see them go anywhere!! The ping command doesn't receive any 'destination unreachable' messages. Here is the relevant section of the routing table. IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.1.201 192.168.1.18 2 10.0.0.0 255.0.0.0 On-link 10.55.44.203 20 10.21.0.0 255.255.0.0 192.168.1.201 192.168.1.18 2

• Can't detect wireless networks, running ubuntu 9.10 on eeepc 1000he

  - by David Brown

  Hi, I am running Ubuntu 9.10 on an ASUS eeepc 1000HE, and my wireless card, RaLink RT 2860, is failing to recognize any wireless networks. It was working fine this morning, until I accidentally hit Fn F2, disabling the wireless card. I hit Fn F2 again to reenable it, but it no longer will detect any wireless networks (and other computers in the household do recognize them). Any help at all will be greatly appreciated! I googled quite a bit and talked to a human about this but could not fix it.

• Impossible to create/format install window 7 on unpartioned HD

  - by fra pet

  Hi guys i am getting nut reinstalling windows 7 on one of those Acer aspire all-in-one... The original OS(windows professional x64) was not starting, after the initial screen the bios was prompted. So step 1: i tried to access the system partition and reinstall everything but could not get at the point step 2: i set the bios to native ide and i tried to insert my original copy of windows professional and do a clean installation, but it does not allow me to format/create other partion form the installation mask step 3: my BAD, i tried to install ubuntu and i clean the whole hard drive, i was getting an error at some point during installation so i decided to get back to windows step 4: Windows 7 again, at the disk screen of the windows installation i entered into the prompt and played around with DISKPART... -i listed the disk and the HD was disk 0. -i selected disk 0. -i CLEAN disk 0 successfully. -i tried to create a CREATE PARTITION PRIMARY but gave an error cache corrupt and disk not up-to-date (after i try to create a partiton in disk 0 it disappear when i try LIST DISK and i have to restart before he can list DISK 0 again, RESCAN did not worked). -tried CLEAN ALL(2 hours) and succeeded. -try again to create primary partition and failed, same errors -try to install my old copy of windows xP pro and it seems to work, it create a partition, format(only quick worked, slow mode was at 0% after 1 hour so i stop), it start installing and around 90% installation said it could not copy a file and he stop -back on windows 7 again, it says that the hard drive has 490+gb unpartitioned but won't create a partition and format. -i tried again DISKPART as i though i messed up with the MBR when i installed ubuntu, so i did all of the instruction below http://www.sevenforums.com/tutorials/20864-mbr-restore-windows-7-master-boot-record.html http://support.microsoft.com/kb/927392 the errors were: on bootsect: the systne partiton was not found, Data error cyclic redundancy check on bootrec /FixMbr: A device attached to the system is not functioning but did not worked, and still can not partiton/format/install on a blank HD i tried some bootable clean disk tool and start infinite loop on the same errors the bios setting are: sata: native ide. if i put AHCL(or something like that does not load the HD and the DVD). quick start/quite start: disabled. Are there any other option or tools i can try before i try change the HD(That is my last option)? Thanks to everyone.

• Trouble joining Windows Server 2008 to Domain

  - by Jim R

  When I try to join my new server to my existing domain I get the following error: "An attempt to resolve the DNS name of a DC in the domain being joined has failed. Please verify this client is configured to reach a DNS server that can resove DNS names in the target domain." I have tried all of the following already: Successfully pinged the domain controller. Ping the new server from the domain controller by IP address and by DNS name. Ping the DC server from the new server by IP address and by DNS name. Changed the network to DHCP (it was originally static). No joy as static or DHCP. Turned off all firewall settings. Added the domain name to 'hosts' file. Added the server name of the primary domain controller to the 'hosts' file in the new server. Any ideas? Thanks in advance for any help! Jim Update: With help from J. Brian Kelly (Thanks) I have managed to narrow down the problem to a DNS issue. Specifically, UDP/53 packets are being sent (they are seen in Network Monitor), but are not getting to the DNS server. But, I do not yet know why. Update: The quested output from IPCONFIG for the HyperV host and the virtual machine.

• Aliased network interfaces and isc dhcp server

  - by Jonatan

  I have been banging my head on this for a long time now. There are many discussions on the net about this and similar problems, but none of the solutions seems to work for me. I have a Debian server with two ethernet network interfaces. One of them is connected to internet, while the other is connected to my LAN. The LAN network is 10.11.100.0 (netmask 255.255.255.0). We have some custom hardware that use network 10.4.1.0 (netmask 255.255.255.0) and we can't change that. But we need all hosts on 10.11.100.0 to be able to connect to devices on 10.4.1.0. So I added an alias for the LAN network interface so that the Debian server acts as a gateway between 10.11.100.0 and 10.4.1.0. But then the dhcp server stopped working. The log says: No subnet declaration for eth1:0 (no IPv4 addresses). ** Ignoring requests on eth1:0. If this is not what you want, please write a subnet declaration in your dhcpd.conf file for the network segment to which interface eth1:1 is attached. ** No subnet declaration for eth1:1 (no IPv4 addresses). ** Ignoring requests on eth1:1. If this is not what you want, please write a subnet declaration in your dhcpd.conf file for the network segment to which interface eth1:1 is attached. ** I had another server before, also running Debian but with the older dhcp3 server, and it worked without any problems. I've tried everything I can think of in dhcpd.conf etc, and I've also compared with the working configuration in the old server. The dhcp server need only handle devices on 10.11.100.0. Any hints? Here's all relevant config files: /etc/default/isc-dhcp-server INTERFACES="eth1" /etc/network/interfaces (I've left out eth0, that connects to the Internet, since there is no problem with that.) auto eth1:0 iface eth1:0 inet static address 10.11.100.202 netmask 255.255.255.0 auto eth1:1 iface eth1:1 inet static address 10.4.1.248 netmask 255.255.255.0 /etc/dhcp/dhcpd.conf ddns-update-style none; option domain-name "???.com"; option domain-name-servers ?.?.?.?; default-lease-time 86400; max-lease-time 604800; authorative; subnet 10.11.100.0 netmask 255.255.255.0 { option subnet-mask 255.255.255.0; pool { range 10.11.100.50 10.11.100.99; } option routers 10.11.100.102; } I have tried to add shared-network etc, but didn't manage to get that to work. I get the same error message no matter what...
