Tips and Tricks for Running Gentoo Edit

I'm a total newbie to Gentoo Linux. But all I ever needed to know about Gentoo I learned from these documentation sources:

Please add more useful info and links here!

Behave in a responsible wayEdit

  • Don't run emerge sync all the time. Actually, more than once a day is useless.
  • Hammering a server can result in your ip getting banned for days or weeks. doh !
  • Use mirrorselect to target the closest Gentoo mirror :
    • emerge mirrorselect (to get and install the tool)
    • mirrorselect -a -s5 (to get a list of the top 5 closest working mirrors from a big list of servers)

Now some common tips Edit

Default Networking Setup Edit

  1. All the modern Gentoo images are set up with static ip addresses of 192.168.0.40, a gateway of 192.168.0.1, and dns nameserver set to 192.168.0.1 . If you have a TAP/Shared network setup, all you should have to do to get a working setup is type /etc/init.d/net.eth0 start. If your Windows side networking is set up shared correctly for TAP/Shared networing, you should now be able to access the internet from colinux. To start networking at colinux boot type "rc-update add net.eth0 default".
  2. To start an ssh server, all you should have to do with a working network connection is type, "/etc/init.d/sshd start". Type "netstat -l" to see if there is a ssh service listening. To add the ssh server to the boot sequence type "rc-update add sshd default".
  3. If your ethernet card is on a subnet of 192.168.0.X, the above will not work for you. Tap/shared networking is not for you, and neither is this default network setup.

Remove "Console Fonts" error at boot Edit

rc-update del consolefont boot

Remove "Can't set Hardware Clock" at boot Edit

Edit /etc/init.d/clock and change this line in start and stop function:

if [ -n "$(grep 'UML' /proc/cpuinfo)" ]

to

if [ -n "$(grep '\-co\-' /proc/version)" ]

Don't forget to do this for the start and stop functions.

Problem: Arch is not set... Edit

Solution Edit

  1. You must have a full portage tree, if not type: emerge --sync or download a portage snapshot.
  2. Look at which version of gentoo you have 2004.3? 2005.1?
  3. Link a profile to /etc/make.profile. Do this by typing the command "ln -s /usr/portage/profiles/default-linux/x86/$VERSION/ /etc/make.profile" , where $VERSION equals your version of gentoo. (2004.3, 2005.1, etc) If the "/usr...../$VERSION/" directory does not exist, you do not have a full portage tree.

Problem: Forced into maintenence mode with a modern Gentoo image? Edit

Solution Edit

  1. Either in your colinux configuration file or on the command line starting colinux, append "root=/dev/cobdX", where X is number of the colinux device that Gentoo is set to.
  2. You may not be allocating enough memory to colinux, either in your colinux configuration file or on the command line starting colinux, append "mem=64". Where 64 is 64 Megabytes. You may of course give colinux more memory, as your hardware allows.
