  • CHEP server: (from outside IISc
  • Faculty (A2 wing):

Proxy server

To access the internet through firefox, you need to set the proxy server. Open firefox, go to "Edit --> Preferences --> Network --> Settings" and tick "Manual Proxy Configuration". Enter the information "proxy.iisc.ernet.in" for the proxy, and "3128" for the port. Tick "Use this proxy server for all protocols", and enter "localhost,, .iisc.ernet.in" in the field that says "No proxy for". Now you should be ready to surf the web.

When you want to surf the web outside IISc, the proxy server asks for a login and a password. You have to get these from SERC by registering as an official IISc person. If you have not registered, then you can access the web using "noauthproxy.iisc.ernet.in" (all the other fields remain the same) which is slower.

Installing Fedora 10

  • Download installation DVD from fedoraproject.org. Restart computer, enter BIOS, select boot from CD/DVD, follow instructions on screen; everything is straightforward.
  • Use System->Administration->Network to configure the static IP, netmask, gateway, DNS servers.
  • NetworkManager applet is buggy in Fedora 10 and does not work well with static IPs. Disable it either from System->Administration->Services, or from command line:
    /etc/init.d/NetworkManager stop
    /sbin/chkconfig --level 35 NetworkManager off
  • Edit file /etc/sysconfig/network-scripts/ifcfg-eth0 and change NETMASK to
  • Start network services so that computer goes online on boot:
    /sbin/chkconfig --level 35 network on
  • Create file /etc/profile.d/proxy.sh:
    export http_proxy
    Without these entries, yum (Fedora package manager) will not work.
  • Set System->Administration->SELinux to permissive mode. Otherwise it will not allow a couple of programs (e.g. Google Earth) to run on your computer.
  • Copy the /etc/hosts so that the computers in the network can be addressed by names (rather than IP addresses):
    scp user@ /etc/hosts
  • Add some repositories (you may need to import key first). Google for the repo definitions (recommended) and install them as instructed, or create a file named google.repo in /etc/yum.repos.d/ with content:
    name=Google - i386

    Same for skype:
    name=Skype Repository

    Install the adobe repo, so that you can later automatically install AcrobatReader:
    wget http://linuxdownload.adobe.com/linux/i386/adobe-release-i386-1.0-1.noarch.rpm
    rpm -Uhv adobe-release-i386-1.0-1.noarch.rpm
    yum install AdobeReader_enu

    For some bells and whistles applications you may need this repo:
    Follow instructions / uncomment baseurl in repo files

    There is a much faster way to install the repos. Use newton ( as a template and copy its repos: scp -r user@* /etc/yum.repos.d Now your computer knows all the repos that are known to newton.
    You may need to uncomment some lines in the *.repo files in the directory /etc/yum.repos.d, so please check that before complaining that yum does not work.
