    Applying system wide proxy

    Hi all,
    I am using my college's wlan connection for browsing and downloading but for updating and installing new packages using software center I have a problem while configuring network proxy to apply system wide proxy.I followed the below links but both of them are not working for me......
    What should I do to fix this problem????

    Please see here : https://help.ubuntu.com/community/AptGet/Howto
    What kind of proxy is it ? Some are trickier than others, such as ISA proxies : http://ubuntuforums.org/showthread.php?t=1802306
    You may have to ask your network admin what kind of proxy they use.

    I've edited the IPV4 settings and changed the DNS severs still the problem persists...
    I think my college's firewall is refusing such connections(system update,apt-get,software center)......

    Re: Applying system wide proxy

    Hmm, may be.. At my univ, they still have the old proxy up and running that works. I cannot use the new auto-woodoo one they set up a couple years ago. Asked them not to drop the old one, and so far they have no intension to..

    Re: Applying system wide proxy

    May be you should ask your network admins what kind of proxy they use (that is why I asked in the first place). With some proxy types, there are some workarounds.

    Re: Applying system wide proxy

    This is what I used long ago, still working: https://help.ubuntu.com/community/Ap...e_a_http-proxy
    On the newer proxy (with login/passwd and other things I did not understand in details), it has never worked. Sysadmins here are using Linux, so that helped
