Assumed you want to find the package that contains the shared object libGLU.so.1, e.g. because a binary is dynamically linked against it, and ldd tells you that the shared library requirements are not met. On Fedora (or any yum-type os) you’d run
$ yum whatprovides */libGLU.so.1
and yum would tell you, that mesa-libGLU comes with /usr/lib64/libGLU.so.1 which could fulfill your need (could because you could also be missing the i686 version of the package, depending on your binary).
The Ubuntu way of achieving the same thing:
$ apt-file search libGLU.so.1
And of course the corresponding package would be libglu1-mesa on any recent Ubuntu os.
With the release of Fedora 18, there have been some changes to the /etc/sysconfig directory. For example, switching the default display manager is no longer done by altering parameters in /etc/sysconfig/desktop but via
# systemctl enable --force displaymanager.service
Therefore, to switch from the default gdm to kdm you’d run:
# systemctl enable --force kdm.service
In contrast to Ubuntu (or even Microsoft Windows) default installations of Fedora do not send the client’s hostname to the DHCP server.
To change this behaviour, add a DHCP_HOSTNAME variable to your /etc/sysconfig/network-scripts/ifcfg-eth0 file (eth0 being your NIC’s interface name):
Of course, this only works if you actually get your IP address via DHCP (since the DHCP server hands off the hostname to the DNS server). If you use a static IP configuration, nsupdate can be used to dynamically update the DNS server records. Examples and instructions on how to use nsupdate can be found at http://linux.yyz.us/nsupdate/ or http://dijks.wordpress.com/2012/07/17/register-a-hostnames-static-ip-with-your-corporate-dns-server/.
