  • FTP file access problem

    - by Fahad Uddin
    I recently got a malware on my website. I have made the backup of the website on my computer and trying to wipe off my FTP. I am trying to delete the root folder but getting this error message on all of the malicious files, Response: 550 Could not delete index.php: Permission denied I am the sole administrator of the ftp so permission should not have been an issue. My host provider seems not to suffer from this problem as his websites are running well without any malware. I have also tried to change the root to 777 to see if the file permission change could help me delete the files but still I am getting the same error. Please help out. Thanks

  • Replace Broadcom "wl" driver with "b43"

    - by Laszlo Boros
    I'm using Ubuntu 10.04.4 LTS, and in my laptop there is a Broadcom BCM4312 wlan card. lspci output: 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) Subsystem: Broadcom Corporation Device 04b5 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at f4500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information Capabilities: [e8] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities: [160] Device Serial Number 81-ac-1d-ff-ff-12-54-92 Capabilities: [16c] Power Budgeting Kernel driver in use: wl Kernel modules: wl, ssb So as you can see, the current (and default) driver is wl - installed with jockey. But I have another Ubuntu based distribution on my laptop (BackTrack linux), which is also 10.04, but it has the b43 driver installed and the overall performance is MUCH better. So I would like to install it on this OS too, but even google didn't help me. So my question is how to install the latest b43 driver on my Ubuntu?

  • Proper fstab entry to mount a samba share in 12.04

    - by JPbuntu
    I am a little confused on the proper fstab entry for a samba share in Ubuntu 12.04 I can get the drive to mount manually by using: sudo mount -t cifs //192.168.2.2/raid_drive /mnt/homeserver -o username=jon,password=password So I tried putting this in fstab: //192.168.2.2/raid_drive /mnt/homeserver cifs username=jon,password=password,iocharset=utf8,mode=0777,dir_mode=07??77 0 0 Which gives me this error in syslog: kernel: [ 2217.925354] CIFS: Unknown mount option mode kernel: [ 2217.936345] CIFS VFS: default security mechanism requested. The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel release 3.3 This guide says to use smbfs although I believe smbfs is deprecated? What is a common fstab configuration for a samba share in Ubuntu 12.04? EDIT: Using the accepted answer below I was initially getting this error message (from dmesg): [ 45.520883] CIFS VFS: Error connecting to socket. Aborting operation [ 45.520990] CIFS VFS: cifs_mount failed w/return code = -115 although it turns out this was due to network connectivity issues, and not related to improper fstab entry.

  • EVOLUTION: No such Calendar

    - by Dennis
    I am using a google calendar with evolution for quite a while now. I was never having any troubles. Just recently, I suppose just after an update, whenever I want to create a new event in evolution (for the just mentioned google calendar) I get the err message "No such calendar". When I dismiss changes an re-open evolution the entry has been added anyway. This is somewhat annoying. I googled, but haven't found anything yet which suggests that it not problem many people have!? Looking for help, maybe someone here knows an answer! I appreciate any suggestion! Cheers, Dennis

  • How can I had some contents from Chrome/Chromium browsers?

    - by MIH1406
    I need to put a "Bookmark us" in my website. But as I searched using Google all the results conclude that no way to do "Bookmark us" for Chrome/Chromium browsers. So I want to either: 1- Hide the content from chrome/chromium browsers. or at least, 2- Show a message if the user's browser is chrome/chromium after clicking that buttong. Here is my "Bookmark Us" script: /** Bookmark Us */ function bookmark_us(url, title){ if(window.sidebar) // firefox window.sidebar.addPanel(title, url, ""); else if(window.opera && window.print){ // opera var elem = document.createElement('a'); elem.setAttribute('href',url); elem.setAttribute('title',title); elem.setAttribute('rel','sidebar'); elem.click(); } else if(document.all) // ie window.external.AddFavorite(url, title); } else { } /** Bookmark Us */ <a href="javascript:bookmark_us('URL','TITLE')">Bookmark Us!</a>

  • Unable to connect to iFolder server

    - by Sven
    I tried to install iFolder on Ubuntu 10.10 server 64 bit using this guide. Everything "worked" except: If I try to acccess the server with http://myurl/admin I get the error-message "Unable to connect to the iFolder server." Has anyone succeeded with this guide, or is there an iFolder specialist who could help me with the last steps? Update 1: I could connect to the /admin-Interface by not changin anything in the config-script. Changing the ServerName in anything else than localhost brings back the error. And changing username and/or password has no affect.

  • Java EE @ No Fluff Just Stuff Tour

    - by reza_rahman
    If you work in the US and still don't know what the No Fluff Just Stuff (NFJS) Tour is, you are doing yourself a very serious disfavor. NFJS is basically a set program of world class speakers and topics offered at major US cities year round. I am proud to share with you that I recently joined the legendary NFJS troupe. My hope is that this will help solve the lingering problem of effectively spreading the Java EE message here in the US. I had my tour debut on April 4-5 with the NFJS New York Software Symposium. I did four of my most favorite talks and it was not that bad for a start - I have more in the coming months in Columbus Ohio, Denver Colorado and Austin Texas. More details on the tour posted on my personal blog. Hope to see you on the tour soon?

  • Why is there no generic implementation of OrderedDictionary in .net?

    - by nonot1
    Why did Microsoft not provide generic implementation of OrderedDictionary? There are a few custom implementations I've seen, including: http://www.codeproject.com/KB/recipes/GenericOrderedDictionary.aspx But why did Microsoft not include it in the base .net library? Surely they had a reason for not building a generic.... but what is it? Prior to posting this message, I did see: http://stackoverflow.com/questions/2629027/no-generic-implementation-of-ordereddictionary But that just confirms that it does not exist. Not why it does not exist. Thanks

  • Once mounted using TrueCrypt, cannot unmount

    - by zeiger
    I have an external HDD and use TrueCrypt for keeping encrypted file containers. After mounting, whenever I try to dismount a file container (using TrueCrypt 7.0a on Ubuntu 11.04), it just does not happen and I get the following message: device-mapper: remove ioctl failed: Device or resource busy Command failed Further, if I close TrueCrypt and then try to start it again, it says that TrueCrypt is already running, but I cannot access it from the Unity sidebar (because it is not there). Also, if I power down my external HDD, the TrueCrypt volume still shows as one of the mounted volumes, but I cannot do anything with it. Any possible work around? I remember this NOT happening in earlier versions of Ubuntu so I am guessing there is something to do with 11.04. Thanks

    Recently the service provider link suddenly broke,while I was updating. Then suddenly while I was trying to boot, i could not.

It started to boot normally. Now my system is back to 12.04 the version i was working with. How does one handle problems like this?

  • How to Install Incompatible Android Apps from Google Play

    - by Chris Hoffman
    Some Android apps on Google Play claim to be incompatible with various devices. There’s a good chance that these apps will run fine on many of these devices – you can bypass this check with root access. Some apps won’t actually work after you install them, but many will. This also solves problems with games that will install but refuse to play – for example, Gameloft games with the “this device is incompatible” message.

  • Login timeout disable?

    - by Sk606
    How can I disable automatic timeout entries in the login screen? Allow me to explain. My typical experience goes something like this: I put my laptop to sleep, then wake it. When it wakes, it comes up with the login screen. I type in my password and it will usually reject it, with a message indicating the login timer has expired. I then enter my password a second time and it logs in. Not the end of the world, but annoying nonetheless. Any suggestions?

  • New to Ubuntu - 12.04.1 Kernel Panic on Installation

    - by user88432
    I'm a complete Ubuntu and even Linux newbie. I'm learning here, so I'm grateful for any info to help me learn more about this. I have a Dell Dimension 2400 with a Pentium 4 and 1GB of RAM. It's older but it's only going to be doing some small stuff for me when I get it up and going. I've tried installing several versions of Linux (but I really, really want Ubuntu) and I keep getting a similar kernel panic message. The problem is I don't have a clue what that means or how to begin fixing it. I would appreciate any help to get my machine up and going. I have already tried Installing alternate Ubuntu versions Burning multiple 12.04.1 disks Installing other versions of Linux I have a picture of the screen to share; however, I can't post due to the fact that I don't have enough reputation points on this forum because I'm a newbie. I would be happy to email you a pic, if you think you can help.

  • How to Export Email "Sent" Folder?

    - by user249493
    A client had her web site and email hosted at "company A". She was switching to "company B" but didn't want to lose her email. I set up a Gmail account, POPed into her webmail account, and pulled the entire inbox into Gmail (for later transfer to her new host). But I forgot about the "sent" folder. Although the hosting plan is still up and running, she changed her domain record to point to the new host. So I can't access the old webmail account via POP or IMAP because the email address needed for authentication now resolves to the new host. Is there any way I can get the contents of the sent folder without having to do a "forward" one message at a time (there are hundreds)?

  • Help me classify this type of software architecture

    - by Alex Burtsev
    I read some books about software architecture as we are using it in our project but I can't classify the architecture properly. It's some kind of Enterprise Architecture, but what exactly... SOA, ESB (Enterprise Service Bus), Message Bus, Event Driven SOA, there are so many terms in Enterprise software.... The system is based on custom XML messages exchanges between services. (it's not SOAP, nor any other XML based standard, just plain XML). These messages represent notifications (state changes) that are applied to the Domain model, (it's not like CRUD when you serialize the whole domain object, and pass it to service for persistence). The system is centralized, and system participants use different programming languages and frameworks (c++, c#, java). Also, messages are not processed at the moment they are received as they are stored first and the treatment begins on demand. It's called SOA+EDA -:)

  • gsm-ussd gives device busy or error (100)

    I am using gsm-ussd to try and query my data balance from my 3G modem. When I issue the commands gsm-ussd -m /dev/ttyUSB0 '*188#' or gsm-ussd -m /dev/ttyUSB2 '*188#' I get either "Device or resource busy" (when it is in used and connected) or "Unknown error (100)".

None of them work, and ttyUSB1 gives a somewhat different problem, as it just give the following message: * Wrong modem device (use -m <dev>)? * Modem broken (no reaction to AT)
