    ubuntu 10.10 Maverick Meerkat lost internet connection 

    I experience this problem after I upgrade my ubuntu from 10.04 ( Lucid lynx ) to 10.10 ( Maverick Meerkat ) . My internet connection drop after a few minute connected to internet.

    Suspect root cause
    1. ipv6

    Solution
    1. I check ipv6 status , if return value = 0 … that’s mean your system still enable ipv6

    cat /proc/sys/net/ipv6/conf/all/disable_ipv6

    2. You need to disable ipv6 by adding the following command in your /etc/sysctl.conf

    sudo gedit /etc/sysctl.conf

    Then paste the following code to the end of line.

    #disable IPv6
    net.ipv6.conf.all.disable_ipv6 = 1
    net.ipv6.conf.default.disable_ipv6 = 1
    net.ipv6.conf.lo.disable_ipv6 = 1

    3. Double check ipv6 status,

    cat /proc/sys/net/ipv6/conf/all/disable_ipv6

    it should return 1

      I ran this and the problem persists. After running the commands and then rebooting, it returns 1 but the connection still drops. I stay connected on other computers, it’s only my Ubuntu box that fails.

      I had a similar problem, my network connection suddenly stopped working. I had been using Maverick all the time, however.

      Fortunately I could use another computer, and found this page.

      Using the GUI, I selected network connections, selected my connection, clicked on the IPv6 tab and set method to ignore.

      My network immediately sprang into life, without the need to reboot, or the need to manually edit any files.

      Ok.. so I am using Ubuntu. This is my first time using it. Just switched over from windows. When I look under my “Network Tools” It shows me the ipv6 thing but I can’t do anything with it. I tried typing in the commands in the terminal but it said that the directory does not exist or something of the like. What can I do. I had internet on for a while and it kept turning off. Now it doesn’t show my internet at all when I click on the connection icon. It still has Linksys as a wireless connection edit option. Any help would be very appreciated. Thank you

      i’am ubuntu user since 7.10 and has no problem to upgrade via update manager to the later version. but since i used 10.04, i can’t upgrade to 10.10. specifically, upgrade button is no available anymore. any suggestion?

      thanks

      Hi Her,

      You can’t see upgrade 10.10 because your update manager set to LTS ( Long term support ) release. You need to change into normal release to see upgrade 10.10.

      1. Open the Software Sources application from the System -> Administration menu
      2. Select the sub menu Updates from the Software Sources application
      3. Change the Release Upgrade drop down to “Normal Releases” and close the application
      4. Press Alt-F2 and type update-manager
      5. Click the Check button to check for new updates.

    download file using wget 

    [lang_en-us]In linux.. you can use wget as your download manager. Wget has many features to make retrieving large files or mirroring entire web or FTP sites easy. How to use it?.. actually it’s pretty simple.

    Say you want to download a url. Just type:[/lang_en-us]

    [lang_ms-my]Dalam linux,korang boleh gunakan wget sebagai download manager untuk download sebarang file.Wget mempunyai pelbagai fungsi yang aku boleh katakan sangat berguna sebagai “simple tetapi advance” download manager. Cara gunakannya agak mudah.. hanya menggunakan arahan wget seperti[/lang_ms-my]

    wget http://ibnuyahya.com/

    [lang_en-us]But what will happen if the connection is slow, and the file is lengthy? The connection will probably fail before the whole file is retrieved, more than once. In this case, Wget will try getting the file until it either gets the whole of it, or exceeds the default number of retries (this being 20). It is easy to change the number of tries to 45, to insure that the whole file will arrive safely:[/lang_en-us]

    [lang_ms-my]Satu soalan… apa yang akan terjadi jika sambungan internet korang terlalu perlahan dan fail yang nak di download tu sangat besar?. Pastinya mungkin korang akan hadapi masalah “connection fail” atau timeout. Dalam masalah ni,wget akan cuba download file tersebut sehingga selesai atau sehingga memenuhi had bilangan percubaan. Default had bilangan percubaan adalah 20 kali, tetapi kita boleh ubah dengan menggunakan arahan –tries. Contoh dibawah aku ubah had bilangan cubaan download menjadi 45 kali.[/lang_ms-my]

    wget –tries=45 http://mirrors.cytanet.com.cy/linux/ubuntu/releases/10.04/ubuntu-10.04-desktop-i386.iso

    [lang_en-us]Now let’s leave Wget to work in the background, and write its progress to log file log. It is tiring to type ‘–tries’, so we shall use ‘-t’.[/lang_en-us]

    [lang_ms-my]jika  malas nak tunggu wget selesai download .. boleh run wget sebagai background process dan log segala aktiviti didalam log file.  arahan –tries juga boleh digantikan dengan -t untuk arahan singkat[/lang_ms-my]

    wget -t 45 -o log http://mirrors.cytanet.com.cy/linux/ubuntu/releases/10.04/ubuntu-10.04-desktop-i386.iso &

    [lang_en-us]The ampersand at the end of the line makes sure that Wget works in the background. To unlimit the number of retries, use ‘-t inf’.

    if you want to resume your download file.. you can add -c parameter[/lang_en-us]

    [lang_ms-my]ampersand di akhir line membolehkan wget di jalankan di belakang tabir walaupun korang dah tutup terminal console korang.

    jika korang nak resume file download, korang boleh tambah arahan -c[/lang_ms-my]

    wget -c http://mirrors.cytanet.com.cy/linux/ubuntu/releases/10.04/ubuntu-10.04-desktop-i386.iso

    [lang_en-us] When you want to download multiple file.. you can use[/lang_en-us]

    [lang_ms-my]Untuk download file melebihi satu file dengan satu arahan[/lang_ms-my]

    wget http://mirrors.cytanet.com.cy/linux/ubuntu/releases/10.04/ubuntu-10.04-desktop-i386.iso http://mirrors.cytanet.com.cy/linux/ubuntu/releases/10.04/ubuntu-10.04-server-i386.iso

    [lang_en-us]or.. create a text file. Since..im not familiar with vi.. i’m using nano ;p[/lang_en-us]

    [lang_ms-my]ataupun lebih kemas kalau korang masukkan senarai url yang hendak di download kedalam text file. boleh gunakan vi kalau korang biasa dengannya. di sebabkan aku tak biasa, aku gunakan arahan nano je hehe[/lang_ms-my]

    nano /tmp/download.txt

    [lang_en-us]Then add your link.. put each link in a separate line[/lang_en-us]

    [lang_ms-my]Lepastu masukkan link korang. pastikan setiap link dipisahkan dengan line yang baru[/lang_ms-my]

    http://mirrors.cytanet.com.cy/linux/ubuntu/releases/10.04/ubuntu-10.04-desktop-i386.iso

    http://mirrors.cytanet.com.cy/linux/ubuntu/releases/10.04/ubuntu-10.04-server-i386.iso

    [lang_en-us]save and run[/lang_en-us]

    [lang_ms-my]Save dan run[/lang_ms-my]

    wget -i /tmp/download.txt

    [lang_en-us]The rest of the wget manual you can read from here http://www.gnu.org/software/wget/manual/wget.html#Top

    next time we explore aget command to enable multithread download just like usual download manager application ;) [/lang_en-us]

    [lang_ms-my]Untuk maklumat lanjut dan lebih terperinci.. korang boleh lawati http://www.gnu.org/software/wget/manual/wget.html#Top

    akan datang kita bincang pula macamana nak gunakan aget untuk fungsi multi-thread download macam kebanyak download manager buat.[/lang_ms-my]
