| * added the following lines to <code>/etc/hosts</code>, to enable running commands like: <code>ping cortex1</code> (if we don't make this change, we can still easily access other machines, but with <code>.visnet</code> attached at the end of their names, see [[VisLab network]] for details)

| = Additional software =
| |
| | |
| In general, stick to the guidelines at [[VisLab machines configuration]] for essential packages and environment variables. In addition, install the software listed below.
| |
| | |
| sudo apt-get install libncurses5-dev libgtk2.0-dev libgtkmm-2.4-dev libglademm-2.4-dev python-tk libqt3-mt-dev vlc
| |
| | |
| == Nvidia graphics card ==
| |
| | |
| Enable the Nvidia proprietary drivers to obtain a decent screen resolution.
| |
| | |
| In order to have multi-screen external monitor support for beamers,
| |
| sudo apt-get install nvidia-settings
| |
| sudo nvidia-settings
| |
| In the 'X Server Display Configuration' menu, select the 'Separate X screen' configuration. Then, edit <code>/etc/X11/xorg.conf</code> (make a backup first) by doing the following under Section 'ServerLayout': switch the <code>Screen 0</code> with the <code>Screen 1</code> strings.
| |
| Restart the xserver and enter nvidia-settings again, you will get some errors in the terminal because of the manual change, furthermore you will now see the correct screen numbering. To resolve the error in the configuration press "save X configuration file". Restart xserver, everything should be ok.

| == Passwordless connection to other machines ==
| |
| | |
| * set up passwordless log-in to the Cortex computers:
| |
| #generate the public and private keys on this computer. enter empty strings when prompted for various answers.
| |
| ssh-keygen
| |
| #the cortex computers (ip addresses 10.10.1.1 to 10.10.1.5) share the same disk, so you need to do the set up only once.
| |
| | |
| #copy the public key you just generated to cortex1, on the user account you want to use there (e.g. icub).
| |
| scp /home/icub/.ssh/id_rsa.pub icub@10.10.1.1: ''<-- be sure to write the colon ":" at the end''
| |
| #log in as 'icub' to cortex1
| |
| ssh 10.10.1.1
| |
| #add the public key to the authorized ones
| |
| cat id_rsa.pub >> ~/.ssh/authorized_keys
| |
| #remove the id_rsa.pub file and log out from cortex1.
| |
| rm id_rsa.pub
| |
| exit
| |
| exit
| |
| #log in again to each cortex computer, to check that the process worked and they don't prompt for a password.
| |
| | |
| * set up passwordless log-in to pc104
| |
| | |
| pc104 boots from a read-only medium, so you cannot modify permanently its authorized_keys file.
| |
| pc104, though, mounts a part of icubsrv's hard-disk and then runs some scripts from there (see the [[pc104]] page for reference).
| |
| #copy the usual public key to the icubsrv (laptop)
| |
| scp id_rsa.pub icub@10.10.1.51:
| |
| #ssh to icubsrv
| |
| ssh icub@10.10.1.51
| |
| #add the key to the authorized ones
| |
| cat id_rsa.pub >> /exports/code-pc104/pc104/hooks/keys/authorized_keys
| |
| #rm the id_rsa.pub file
| |
| rm id_rsa.pub
| |
| | |
| === PC104 authentication caveat ===
| |
| | |
| For pc104 it might be necessary to add a [http://www.securityfocus.com/infocus/1806 StrictHostKeyChecking=no] option argument to ssh (because there are different incompatible keys depending on the pc104 hardware setup, i.e., with or without pen):
| |
| gnome-terminal --window-with-profile=pc104 -e "ssh -o StrictHostKeyChecking=no icub@10.10.1.50 -X"
| |
| | |
| == Customization of GNOME ==
| |
| | |
| We used the same [[Chico2 desktop machine configuration#Customization_of_GNOME_panel|buttons that we put on Chico2]]. We copied the files by typing this on chico'''2''':
| |
| scp ~/Pictures/* chico3:/home/icub/Pictures
| |
| and then we manually added the buttons one by one on the top toolbar of chico3.
| |
| | |
| == Adding a new terminal button ==
| |
| | |
| Example for the button to open the gnome-terminal on cortex1:
| |
| * right click on the panel and select "add to panel"
| |
| * select "custom application launcher"
| |
| * click on the icon and select the directory where your icons are, typically ~/Pictures/
| |
| * click on open, then select the picture for this particular button
| |
| * write this in the "command" field:
| |
| gnome-terminal --window-with-profile=cortex -e "ssh icub@10.10.1.1 -X"
| |
| * set the name to something like: ssh icub@cortex1
| |
| | |
| Note about gnome-terminal profiles: the profile we have specified specified (--window-with-profile='''cortex''') does not exist by default, we need to create it. These profiles are used to give terminals on different machines different colors (e.g., all terminals running in a cortex computer will be blue, terminals local to chico2 will be white, etc.). To create the "cortex" profile do this:
| |
| * open a terminal on, say, cortex1
| |
| * click on File, select "new profile" and name it "cortex", then choose the colors
| |
| * cortex windows usually are blue background with white text, while pc104 windows are yellow with black text.
| |
| | |
| == Nautilus buttons ==
| |
| | |
| For the buttons that start the file manager Nautilus on pc104 and on cortex (once again, all cortex computers share the same disk, so you need only one button for them) you should use these lines of code:
| |
| nautilus sftp://icub@10.10.1.50/home/icub/
| |
| nautilus sftp://icub@10.10.1.1/home/icub
| |
| | |
| After you are done browsing a remote machine disk with Nautilus, don't forget to unmount the volume (right-click the relevant icon on the desktop).
| |
| | |
| == Desktop background ==
| |
| | |
| Last but not least, you can change the default Ubuntu desktop background to something fancier:
