• Google Chrome doesn't respond user actions correctly

  - by Carlos A. Junior

  Recently I've changed my OS to Ubuntu 12.04 (Cinnamon, 64 bits) from Mint 13 (KDE, 64 bits) and one same bug still appears on new installation. The Google Chrome it seems that don't refresh (repaint) page based on my interactions. Example: When i'm try comment an Youtube vídeo, when i click on textarea, o cursor don't appear inside of textarea, BUT, when/if i change to another tab and return the cursor appears...OK... If i start write some text...according i'm typing the chars don't appers...again if i change to another tab and return the typed text appears on textarea. Other cases that this bug appears: Modal boxes link...don't show the modal; Forms inside modal boxes don't show typed chars; The common Discus comment plugin don't work when focused; I don't have any idea of reason of this bug. (video driver, window manager, Chrome bug ?, i don't know) Any idea to solve this ? Additional informations: Google Chrome 22.0.1229.79 (Official Build 158531) OS Linux WebKit 537.4 (@129177) JavaScript V8 3.12.19.11 Flash 11.3.31.331 User Agent Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.79 Safari/537.4 Command Line /opt/google/chrome/google-chrome --flag-switches-begin --flag-switches-end Executable Path /opt/google/chrome/google-chrome Profile Path /home/carlos/.config/google-chrome/Default Kernel version: 3.2.0-31-generic-pae Ubuntu 12.04 Best regards.

• Windows Server 2008 network speed slow, Xen 3.4.3 HVM ISO

  - by Elliot.Bradshaw

  I've setup a VM running Windows Server 2008 on a host node running Xen 3.4.3-5 and the following kernel: 2.6.18-308.1.1.el5xen #1 SMP Wed Mar 7 05:38:01 EST 2012 i686 i686 i386 GNU/Linux The network speed on the VM is very slow--using the online speed tests I can only get it up to 8-9mbps. The line is 100mbps burstable and the host node has no problem achieving those speeds. If it setup a VM running CentOS, it too has no problems achieving those speeds. I've done some pretty exhaustive troubleshooting, but nothing has helped: New VM installations of Win2k8 do have the same network problem. Upgrading to most recent kernel-xen did not help (2.6.18-308.1.1.el5xen). Upgrading from xen 3.4.0 to xen 3.4.3-5 did not help. Disabling Windows firewall, etc did not help. Changing network card device config from auto negotiation to manually be 100mbps full duplex did not help. Changing the network receive buffer packet size did not help (tried all combos from 64k to 8k). At this point I'm pretty much out of ideas--any help would be appreciated!

• Boot loop that I cannot bypass

  - by lonewaft

  Recently, on a laptop that I've used for a while, I had a strange issue where OS files were corrupted (device manager) and Windows 8 was hung after the login screen, so I reinstalled Windows 7 over the existing Windows 8 installation, and it worked for a couple days. Today, when I tried to use my laptop, it was stuck on a boot loop. Right after the BIOS screen, it would show a flashing underscore, then restart the computer, again and again until I removed the battery. I tried booting to a windows 7 install CD, but the same flashing underscore - reboot sequence happened when I tried. I tried moving the boot priority around (HDD first, CD/DVD first, even USB first) but nothing changed. After about an hour of tinkering with it, I listened to the HDD sounds, and it sounded like the HDD was trying to spin up, but failing (whining noise increasing in frequency that stopped and started in sync with the system restarting). I am planning to replace the HDD, but I'm still confused as to why a faulty HDD would stop the laptop from booting to my install DVD (tried it on a different computer, it booted from that CD fine). Anybody here have any idea why this might be happening?

• Cannot access SMC8014WG-SI provided by TimeWarner/RoadRunner administrative interface...

  - by Matt Rogish

  I just received installation of RoadRunner internet/TV/Voice and I was given a wi-fi router from the TimeWarner folks. The model is a SMC SMC8014WG-SI. Unfortunately, the password it uses is WEP and that is, as we all know, completely insecure. The tech that was here didn't know how to change it to something like WPA2 w/TKIP, and I was on hold for 20 minutes with the TimeWarner folks before I gave up. My problem is that the default web interface (http://192.168.0.1) isn't responding. I can ping it, I can access the internet through it, but I can't get to the admin interface. I did a "hard reset" of the device but still no dice. My suspicion is that the wi-fi admin interface is disabled (a common setting) but the wired interface isn't working on either of my two laptops (I've tried two laptops with two different cables, no link light activated). Am I SOL? Did they lock this down so I can't do what I want to do? Worst-case is I just hook up my go-to WRT54G router to the other modem and leave this one turned off, but I'd rather use their hardware to avoid any "It's not our problem" in the future. Any thoughts? Thanks!!

• How to monitor process hogging CPU on a remote server

  - by sergeb

  I have a remotely hosted (virtual, VMware) dedicated server (Windows 2008 Server Web edition w/ SP1) that I can only connect to over Remote Desktop. Lately, a process hogs CPU for ~40 minutes most every day (at a random hour) and brings all web sites on the server down. While this is going on I also cannot connect using Remote Desktop to investigate on what is that process... Promptly after 40 min I can RD and the first thing I see on the Perf Monitor is that there was something topping the CPU at 100% and stops just before I'm able to RD... I'm aware of the beginning and end of this for I have monitors setup that email me up/down status of the web sites but I'm locked out while this is happening - can't RD to the server until it's over (and too late to see the Task Manager/Process Explorer picture). What is the best way/tool to setup on the server to continuously monitor all processes so when this happens I login and "replay" it to find the process causing this trouble? (I have no control over the virtual/VMware setup for it is hosted by a 3rd-party but I have most full control over my dedicated machine) Thanks in advance!

• Is there a way to "burn" audio to an ISO? (as an audio CD)

  - by Sootah

  I have an audiobook that I've downloaded via their download manager, and it's loaded into their cutesy little audio program that they force you to use. I can play the book just fine using their proprietary software, and while it's annoying when using my PC, it's utterly UNBEARABLE when I try to listen to it on my Blackberry. The program is INSANELY slow, it literally takes around 30 seconds to switch between tracks, so if I've forgotten where I am in the book it takes me around 15 minutes to finally get to where I was at. I've looked everywhere on how to transcode the book to .MP3, but evidently with their current format it's either extremely convoluted (and I have no desire to dick around with installing some older version of the codec, getting a different transcoding app, and then wrestling with getting it to actually work). Since I'm able to burn a copy of the book to an audio CD, I figure the best way to go about this is to just make the CDs and then rip them off of those to .MP3. In order to avoid wasting two hours, not to mention 14 CD-R's, I was wondering if there's a way to "burn" to an .ISO instead of an actual CD-R. I currently have SlySoft's Virtual CloneDrive installed, so I can mount .ISO's easily enough, but now I want to actually create an ISO via the CD burning process. Just in case I've not explained myself very well, here is an overview of what I intend to do: "Burn" a set of Audio CD .ISOs from the audiobook (hopefully I can do this using Windows Media Player, otherwise I'll be forced to use the audiobook app) Mount an .ISO in Virtual CloneDrive Rip the audio tracks on the mounted .ISO to .MP3s Repeat steps 2-3 until the entire book is in .MP3 format Copy .MP3s to my Blackberry so that I'm not driven insane every time I want to listen to the book in the car, and be able to use Winamp when listening on my computer EDIT: I'd suppose a rather concise way to put it is that I need something that will emulate a CD-R drive, so that you can select it as the output drive in whatever app your burning the audio CD from. (I'd suppose that when you "insert a blank CD-R" the app would then ask you what file to save to)

• Sharing disk volumes across OpenVZ guests to reduce Package Management Overhead

  - by andyortlieb

  Is it feasible to create a single "master" OpenVZ guest who would only be used for package management, and use something like mount --bind on several other OpenVZ guests sort of trick them into using the environment installed by the master guest? The point of this would be so that users can maintain their own containers, and yet stay in sync with the master development environment, so they'll always have the latest & greatest requirements without worrying too much about system administration. If they need to install their own packages, could put them in /opt, or /usr/local (or set a path to their home directory)? To rephrase, I would like several (developer's, for example) OpenVZ guests whose /bin, /usr (and so on...) actually refer to the same disk location as that of a master OpenVZ guest who can be started up to install and update common packages for the environment to be shared by all of this group of OpenVZ guests. For what it's worth, we're running Debian 6. Edit: I have tried mounting (bind, and readonly) /bin, /lib, /sbin, /usr in this fashion and it refuses to start the containers stating that files are already mounted or otherwise in use: Starting container ... vzquota : (error) Quota on syscall for id 1102: Device or resource busy vzquota : (error) Possible reasons: vzquota : (error) - Container's root is already mounted vzquota : (error) - there are opened files inside Container's private area vzquota : (error) - your current working directory is inside Container's vzquota : (error) private area vzquota : (error) Currently used file(s): /var/lib/vz/private/1102/sbin /var/lib/vz/private/1102/usr /var/lib/vz/private/1102/lib /var/lib/vz/private/1102/bin vzquota on failed [3] If I unmount these four volumes, and start the guest, and then mount them after the guest has started, the guest never sees them mounted.

• 4.00gb (3.25gb usable) in Windows 7 x64

  - by dotnetdev

  Hi, I have setup Windows 7 Ultimate x64 on my PC. I have 4gb RAM and my BIOS states the correct amount (4096mb), but I cannot Windows (System Manager) says I have 4.00gb (3.25gb usable). This seems to be a popular issue, and I have looked for an integrated video card (integrated with my chipset) to disable but haven't found anything. What else can be preventing me from seeing all 4gb? When I had Vista 32bit, it would say 3.25gb RAM not 4.00gb (3.25gb usable). I have an x64 CPU and when I brought my RAM, I used a compatibility tool from Crucial (the memory vendor) to test how much memory my PC can support and 4gb was the answer (this was a windows app I think). Chipset is Intel(R) G33/G31/P35/P31 Express Chipset PCI Express In the bios, I looked for an onboard video card (integrated) and there was no such thing, but a couple of other onboard devices. There are also no "Resource Mappings" settings. FURHTER DETAILS: Chipset North Bridge: Intel Bearlake G33 South Bridge: Intel 82801IR ICH9R Maximum Memory Amount 8 GB Graphics Controller Type Intel GMA 3100 (Enabled) I guess the first thing is, how do I disable the graphics controller? EDIT: This thread (http://forums.legitreviews.com/about23417.html) indicates the issue is with memory mapped devices, but someone on this thread says that does not apply to x64. The rest of the comments points to a mobo issue for the guy who started that thread. Thanks

• Best option for storage clustering

  - by sam

  I'm working on an application that requires a large amount of storage space and I want to handle storage 'in-house' (Much cheaper than, say, S3) so we will have multiple servers (Initially 4) with large amounts of storage (6TB each). The storage will need to be very flexible and configurable, each piece of data should be replicated on at least 2 servers and must be easily readable/writable from ether an API of a UNIX device/file/folder like a normal drive, I don't mind which. We must also be able to easily offload content to our HTTP CDN (Edgecast), it doesn't need to have built in HTTP support but if it doesn't I'm going to have to write something to get the files onto HTTP so they can be pulled by the CDN. I've looked at a lot of solutions including Eucalyptus Walrus OpenStack Object Storage MogileFS and some others which I can't remember All the servers will be running RHEL 6, they have 4x1.5TB drives which will be RAID1'd into a single partition. All the servers have 1GB/s connections between them and 100MB/s connections to the internet with unlimited bandwidth. They have 2x2.66ghz processors. I understand there isn't a single, perfect answer but it would be nice to get some pointers.

• Poor gaming performance with hyper-v installed in windows 8

  - by SnowCrash

  I am getting very poor gaming performance on my Windows 8 host OS with Hyper-V installed but no guest machines running. For example World of Tanks reports 60-70 FPS without Hyper-V installed and 4-14 FPS with it installed. A similar, dramatic, hit is observed in several other games so the issue is not WoT specific. To make the point clear, I am not trying to run games in a virtual machine. I don't even have a VM running while observing this effect. I simply have the Hyper-V feature installed. My system specs: AMD Phenom II 965 (3.4 GHz) AMD Radeon 6950 2GB (XFX Double D HD-695X-CDFC) 16GB DDR3 1333 AMD 790GX chipset Mainboard (Gigabyte GA-MA790GPT-UD3H) I have tried every AMD driver from 12.8 to the current 12.11beta8, virtualization is enabled in the BIOS settings, the onboard 3300HD video device is disabled in BIOS and I have read the MSDN blog entry here regarding a similar issue in Server 2008 that was resolved in 2008 R2 (and hopefully not regressed in Win 8). I'd like to be able to use Hyper-V for development and testing at home (I am a sysadmin/software developer professionally). If, however, I can't also use my home system for entertainment I'll have to scrap those plans.

• ADSL with RFC 2684 Bridging

  - by Axel Isouard

  My new ADSL line is now enabled, I can finally use my Netgear DM111Pv2 to use to the Internet. My ISP has told me a big surprise : I don't need to use a login and a password to connect to the Internet, then I must use the RFC 2684 bridging mode. It works pretty fine on the ADSL modem's side, but I've spent one night trying to figure out how to connect to the Internet through this modem. I only have a Fonera 2.0n and a computer running Gentoo Linux. I've been trying to use the br2684ctl utility with brctl on my Gentoo, first I've configured my kernel in that way : CONFIG_PPP=y CONFIG_PPP_BSDCOMP=y CONFIG_PPP_DEFLATE=y # CONFIG_PPP_FILTER is not set CONFIG_PPP_MPPE=y # CONFIG_PPP_MULTILINK is not set CONFIG_PPPOATM=y CONFIG_PPPOE=y CONFIG_PPP_ASYNC=y CONFIG_PPP_SYNC_TTY=y [...] CONFIG_ATM=y CONFIG_ATM_CLIP=y CONFIG_ATM_CLIP_NO_ICMP=y CONFIG_ATM_LANE=y CONFIG_ATM_MPOA=y CONFIG_ATM_BR2684=y # CONFIG_ATM_BR2684_IPFILTER is not set And I still get these messages : cirus nais # br2684ctl -b -c 0 -e 0 -a 8.35 br2684ctl[8041]: Interface "nas0" created sucessfully br2684ctl[8041]: Communicating over ATM 0.8.35, encapsulation: LLC br2684ctl[8041]: Fatal: failed to connect on socket; No such device The brctl utility keeps telling me "Invalid argument" each time I try to add the nas0 interface into my bridge, I'm honestly hoping I'm doing wrong. I've been following this README carefully and this tutorial on setting up a PPPoE connection with Gentoo, but the PPPoE interface just tries to start, and nothing special related to PPP happens, I can't see the interface when I do ifconfig. So, I'm asking you if there's something huge I've been missing since the beginning ! Maybe I should wait to buy a new router fully supporting the RFC2684 bridging mode, but I'm more interested in setting up this mode on my Fonera 2.0n and even my Raspberry Pi !

• Cannot establish a network connect to VMWare Fusion VM

  - by twolfe18

  I am running Snow Leopard 10.6.2 (not the server edition) with VMWare Fusion 3.0.0 and I trying to get my Ubuntu 9.10 x86_64 VM working. I am using a bridged connection, and I have an internet connection FROM the Ubuntu VM (I can download updates, ping websites, etc), but I cannot connect TO the Ubuntu box from any other device on my network. I am trying to get Mongrel up on the Ubuntu VM for some Rails stuff, but it's not working. I know Mongrel/Rails is not the problem because if I start the server on the Ubuntu VM, background the process, and then wget the index page, it works. I just cannot connect to the site from another IP. I have tried using a static IP and a DHCP IP configuration on the Ubuntu VM, neither work (for incoming connections, both work for outwards). I have port scanned the Ubuntu VM, and it appears that all ports are closed. However, the Ubuntu VM does respond to pings. I noticed a similar question here: http://serverfault.com/questions/99757/setting-up-a-bridged-network-with-vmware-fusion, but no answer. Any ideas?

  I have ubuntu 8.04 and ubuntu 10.04 on my laptop, and i want to reclaim all the ubuntu 8 space so that i have just one operating system on my laptop. how can i do it? the output of sudo fdisk -l is as follows: sudo fdisk -l Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x31a431a3 Device Boot Start End Blocks Id System /dev/sda1 * 1 4959 39833136 83 Linux /dev/sda2 4960 5233 2200905 82 Linux swap / Solaris /dev/sda3 5234 12852 61192552 83 Linux /dev/sda4 12852 19458 53062657 5 Extended /dev/sda5 12852 19182 50847744 83 Linux /dev/sda6 19182 19458 2213888 82 Linux swap / Solaris i dont know which of sda1, ..., sda 6 etc ubuntu 8 is on. how can i find that out? The actual task is that i think a lot of space is devoted to ubuntu 8, if there is no easy way to get rid of it, then i want to repartition the disk so that about 50 GB of hard disk space is given to ubuntu 10's home folder from the ubuntu 8's home folder. but i hope that there is an easy way to get rid of ubuntu 8 alrogether and just have ubuntu 10 on my system.

• Launching Installer Via Powershell and WinRM and Nothing Happens

  - by Nick DeMayo

  I'm currently working on a Powershell script to run some Microsoft Hotfix installers remotely on several Windows Server 2008 R2 servers that I manage. Basically, the script copies all the appropriate files up to the server, and then runs the installer via Invoke-Command, like so: function InstallCU { Write-Host "Installing June 2013 CU..." Invoke-Command -ComputerName $ServerName -ScriptBlock { Start-Process "c:\aaa\prjcusp2\ubersrvprj2010-kb2817530-fullfile-x64-glb.exe" -ArgumentList "/passive" } } If I run the "Start-Process" command locally on the server, the installer runs properly. However, when trying to run it remotely, nothing happens (actually, I can see the installer start up in Task Manager, but it closes a couple seconds later and doesn't run). I've attempted giving the Invoke-Command -Credentials, I've turned off UAC on the server, and I've ensured that my WinRM settings (running 'winrm quickconfig' and setting TrustedHosts to *) are correct. I've also tried having the Invoke-Command script run a local Powershell script to run the installer and changing the Argument from '/passive' to 'quiet' (in case it can't remotely launch something that has a UI), but again, no dice. Is there anything else I can try, or am I just not going to be able to do this?

• When I ping Internet addresses like yahoo or Google, I get 2 reply packets and 2 lost packets.

  - by navi

  I have Airtel broadband and a Tata broadband connection. i have around 50 PCs connecting through an airtel broadband connection. Both are dsl connections with my phone line going into dsl modems and an Ethernet cable going from dsl modem directly into a switch. Currently, only airtel connection is connected with static IP on my private lan and using the airtel ISP DNS servers as DNS IP address and the default gateway is 192.168.1.1 (IP add. of the dsl modem). All PCs are connected in a work group. When in full use, my users complain of certain web pages are not opening. When I ping Internet addresses like Yahoo or Google I get 2 reply packets and 2 lost packets. I suspect that a single broadband connection is not able to sustain 50 simultaneous downloads/browsing. Is there any device which connect to both DSL and make one line so that its give me high speed simultaneous browsing. Help needed urgently. Thank you all to those who reply.

• Dual booting Linux/Win7, Grub refuses to load Win7

  - by JohnB

  Decided to give Linux Mint a try (Ubuntu's interface annoys me), so I installed it with the intention of dual booting with Windows 7. Installation went fine, but now I can only boot into Linux Mint. Grub lists two Windows 7 menu options, but selecting either of them causes an "unknown file system" error and dumps me into a Grub recovery prompt. There, I have to manually reset the root and prefix options, as they reset hd0,msdos6 when they should be hd0,msdos5. I ran Boot Repair twice, once to fix grub errors, once to rebuild the MBR, but it didn't fix anything. Here is the log: http://paste.ubuntu.com/1029675/ fdisk output: Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 206848 1486249145 743021149 7 HPFS/NTFS/exFAT /dev/sda3 1486249982 1953523711 233636865 5 Extended /dev/sda5 1486249984 1945141247 229445632 83 Linux /dev/sda6 1945143296 1953523711 4190208 82 Linux swap / Solaris grub.cfg: ### BEGIN /etc/grub.d/30_os-prober ### menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os { insmod part_msdos insmod ntfs set root='(hd0,msdos1)' search --no-floppy --fs-uuid --set=root 86184D18184D091F chainloader +1 } menuentry "Windows 7 (loader) (on /dev/sda2)" --class windows --class os { insmod part_msdos insmod ntfs set root='(hd0,msdos2)' search --no-floppy --fs-uuid --set=root 56D84F84D84F60FB chainloader +1 } ### END /etc/grub.d/30_os-prober ### I have found a few similar troubleshooting guides so far, but so far no amount of updating/configuring Grub has been successful.

• Can any iSCSI NAS appliance replicate / clone a LUN to an external drive?

  - by Boden

  I would like to backup using Windows Imaging to some kind of NAS appliance. I believe this will require the NAS to support iSCSI. I would then like the appliance to support the replication of the iSCSI LUN to an external eSATA or USB disk connected directly to the appliance. I've found plenty of NAS appliances that can do iSCSI and replicate to an external drive, but none that I've found thus far can do both at once. That is, the devices can do iSCSI, but then the replication feature doesn't work. The idea here is to backup to an appliance located in a secure office far away from the server room. Offsite backups to external hard drive could be managed from the appliance. The benefits of such a setup would be: 1) very unlikely that fire or random theft would affect both server-room backup and "remote" backup appliance 2) offsite backups could be managed by multiple trusted people without granting access to server room 3) Windows imaging provides poor man's deduplication, so each backup volume can contain a decent backup history. I understand why this would be a non-trivial thing to implement, but I'm wondering if such a thing exists? Preferably a tabletop, low to medium cost device. Alternative solutions welcome. NOTE: I'm backing up very few but very large files, so file replication is not a good option.

  This has gotten to be a major problem at our company and depending on who I ask, the problem either does not really exist (mfr. and vendor) or is insoluble ( according to most users including techs who know how to prove their point). The problem involves getting a normal Windows 7 system to connect to a normal Server 2008 R2 Server over a cellular router (usually called a Mifi). A very few brands/models appear to work but the majority cannot make the connection. Since it is a cellular device, there are many variables that come into play and I wondered if anyone had ever found a consistent way to either make one work or else prove to the providers that their equipment was at fault. They all specifically state “VPN use” on the sales brochures. But few if any work. And those that do are not reliable. From a standpoint of pure knowledge, I just wondered if anyone knew the real reason why they fail? Pptp, L2tp, IPsec doesn’t matter. I have not tried Shrew or OpenVPN and am using strictly MS Windows protocols. Plenty of Google Searches back up my complaints but none seem to be any closer to knowing "why" they fail, just that they do. This is a "quest for knowledge"question. I don't expect a solution. Just a reason for the problem if anyone has any ideas.

• Problem with wireless networking

  - by Rodnower

  Hello, I have atheros wifi hardware, intell chipset, gigabyte laptop and CentOS 5 installed. Now I try to use wireless network and get problems. First of all I want to say that I have 2 OS on my laptop, and when I load Windows XP I still may to access to the wireless network. First I try to get it on Linux was to make active wlan0 interface in: system - administration - network but I get: Determining IP information for wlan0... failed. Second I try also was unsuccessfully: [root 1 network-scripts]# ifup-wireless Error : unrecognised wireless request "off" This relevant output of iwconfig is: Warning: Driver for device wlan0 recommend version 21 of Wireless Extension, but has been compiled with version 20, therefore some driver features may not be available... wlan0 IEEE 802.11 ESSID:"" Mode:Managed Frequency:2.462 GHz Access Point: Not-Associated Tx-Power=27 dBm Retry min limit:7 RTS thr:off Fragment thr=2352 B Encryption key:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 {output not in the original format} The same things are happen even if I do: modprobe wlan0 (this not get error) Important to say that modprobe not succeed to find ath_pci, tharefor I decide to download latest version of the madwifi driver from http://madwifi-project.org. I extracted this, but when I make this, this is what I get: [root 1 madwifi-0.9.4]# make /bin/sh: line 0: cd: /lib/modules/2.6.18-164.el5/build: No such file or directory Makefile.inc:66: * /lib/modules/2.6.18-164.el5/build is missing, please set KERNELPATH. Stop. I tried to set KERNELPATH, but I think that it was incorrect: [root 1 madwifi-0.9.4]# make KERNELPATH=/lib/modules/2.6.18-164.el5/kernel/ /bin/sh: cc: command not found Makefile.inc:81: * Cannot detect kernel version - please check compiler and KERNELPATH. Stop. Some one have any ideas? Thank you very much for ahead.

• Software distribution from web server to client using PHP/FTP

  - by Jenolan

  I develop and maintain a number of add-ons and utilities for various widget (mainly aMember) which generally means I need to install php based codes onto other people's systems. Whilst I have a VPS and have access to rsync and all sorts of yummy tools most of the people I deal with have a basic ftp access and that's all folks. To upload from my local system is also a problem as I am satellite based (two-way) so it is fairly slow and expensive and in any case the files are already on my server. So there is no rsync, fxp, ssh and I can't really install anything as it is obviously not my system, they would be justifiably miffed if I started installing file managers or other things onto their sites. What I have been trying to find is a utility that I can run on my server from the web, preferably php based, that will be like a file manager but a bit different. Two panels. LH-Side the local server .. pretty much like a standard FM application RH-Side ability to login via FTP to the clients system Then I can fiddle as required. The closest thing I have found is net2ftp but it doesn't have the gui interface, at the moment I simply ssh into my server power up ncftp and run that way, but something easier to use would be mucho niceness. Thanks in advance! Larry

• Better way to design a database

  - by cMinor

  I have a conceptual problem and I would like to get your ideas on how I'll be able to do what I am aiming. My goal is to create a database with information of persons who work at a place depending on their profession and skills,and keep control of salary and projects (how much would cost summing all the hours of work) I have 3 categories which can have subcategories: Outsourcing Technician welder turner assistant Administrative supervisor manager So each person has its information and the projects they are working on, also one person may do several jobs... I was thinking about having 5 tables (EMPLOYEE, SKILLS, PROYECTS, SALARY, PROFESSION) but I guess there is a better way of doing this. create table Employee ( PRIMARY KEY [Person_ID] int(10), [Name] varchar(30), [sex] varchar(10), [address] varchar(10), [profession] varchar(10), [Skills_ID] int(10), [Proyect_ID] int(10), [Salary_ID] int(10), [Salary] float ) create table Skills ( PRIMARY KEY [Skills_ID] int(10), FOREIGN KEY [Skills_name] varchar(10) REFERENCES Employee(Person_ID), [Skills_pay] float(10), [Comments] varchar(50) ) create table Proyects ( PRIMARY KEY [Proyect_ID] int(10), FOREIGN KEY [Skills_name] varchar(10) REFERENCES Employee(Person_ID) [Proyect_name] varchar(10), [working_Hours] float(10), [Comments] varchar(50) ) create table Salary ( PRIMARY KEY [Salary_ID] int(10), FOREIGN KEY [Skills_name] varchar(10) REFERENCES Employee(Person_ID) [Proyect_name] varchar(10), [working_Hours] float(10), [Comments] varchar(50) ) So to get the total amount of the cost of a project I would just sum the working hours of each employee envolved and sum some extra costs in an aggregate query. Is there a way to do this in a more efficient way? What to add or delete of this small model? I guess I am missing something in the salary - maybe I need another table for that?

• HDD cannot be booted from

  - by K.Wong

  I have an ASUS A52F, no mods, with Win7 preinstalled. There is one hard drive, two partitions, one for the OS (C:) and one for data (D:) After laptop trauma, i.e. I dropped it, it still worked fine. However, when chkdisk was run on the C: drive chkdisk crashed, and Windows is unbootable. Windows Startup Manager utility was run, but error code 0xc00000e9 was given. Windows help db shows that this is a BIOS problem, however in BIOS setup the drive can be accessed, and folders can be shown. I also burned a Ubuntu 12.04 distro, and booted off it, but my internal HDD is missing and cannot be accessed. When installation program is run the HDD shows up as a location to install to yet the drive is shown as blank. tl;dr: HDD damaged, chkdisk crashed. Windows 7 is unbootable. Given error code, according to Microsoft db, is a BIOS problem, yet in BIOS the drive is accessible. different OS (Ubuntu 12.04), booted off a distro, yet HDD is inaccessible. Quick help appreciated.

• How to restrict zone transfers to specific authorized servers only

  - by JonoB

  I recently failed a PCI compliance scan because of the following: This DNS server allows unrestricted zone transfers. Attackers may be able to use this information to gain knowledge on the structure of your networks to aid in device discovery prior to an actual attack. And the suggested solution is as follows: Reconfigure this DNS server to restrict zone transfers to specific authorized servers only. I am running a dedicated Linux Centos server. My understanding is that I have to edit the /etc/named.conf file, which I have done and the the relevant part is as follows: options { acl "trusted" { 127.0.0.1; xxx.xxx.xxx.001; //this is one of the server's ip's xxx.xxx.xxx.002; //this is another server's ip }; allow-recursion { trusted; }; allow-notify { trusted; }; allow-transfer { trusted; }; }; I then restarted the named service /etc/rc.d/init.d/named restart and requested a re-scan, which failed again for the same reason. Am I missing something obvious here?
