CS209-01 Summer 1 2005 Lab 5 / HW 4

Starting X Server

• run startx
• if you encounter any difficulties you can always kill the X server by [CTRL] + [ALT] + [Backspace]
• modify /etc/ssh/ssh_config and uncomment this line
  ForwardX11 yes
• ssh to 192.168.8.1 with your regular cs domain user name and password
• run xterm on liberec and it should display on your screen
• similarly you can run netscape or any other browser and have it displayed the cs209 web pages on your monitor

• run YaST   from K Menu -> System or
  run YaST2 from a command line
  click on Install and Remove Software
  • Select Autocheck at the bottom of the window to check for dependencies automatically
  • Under the filter chose Selections
  • and install all packages under C/C++ , Kernel , and KDE developments

unlikely to have to do that for stable versions (stable -even #, developmental -odd #)
• the process revolves around .config in the root of source tree /usr/src/linux
• make   xconfig   or   make   menuconfig
  to make a compilation little faster, go through all options listed and disable the parts of the kernel you will not need
• make   dep
• make   clean
• make   bzImage
• make   modules
• make   modules_install
• make   install
• check the menu.lst under boot/grub and make sure you have a backup image listed
• reboot with the new kernel
• check that you are using the kernel just compiled: uname   -a
  and you should see something like (notice the time when the kernel was compiled):
  Linux ivantest 2.6.11.4-20a-default #1 Tue Jun 8 12:40:46 MDT 2005 i686 i686 i386 GNU/Linux

• start YaST and under System click on /etc/sysconfig Editor
• Under System -> Logging click on the SYSLOG_DAEMON and change the default daemon to be syslogd
• if you get an error message that restart failed try to run /etc/init.d/syslog   restart
• if you get an error message that syslogd is not installed then start YaST again and install it - search for syslog and select the package(s) ...
• start the syslogd: /etc/init.d/syslog   start
• check that syslogd is running on your system - how did you do that ?
• will syslog start after the next reboot ?
• decipher the default syslog.conf on your system : describe and comment what is and what is not logged. What would you change, why ?
• cp   /etc/syslog.conf   /etc/syslog.conf.orig
• implement 2 of your suggestions : modify the config file, make sure that it works

• as user root run
  find   /boot     /etc     /lib/modules   /var     -mtime   -1   -ls   |   grep   "Jun     8"   |   tee   /tmp/listing_lab5   |   less
• In your lab report explain the command pipe above

• describing the process, difficulties you encountered, and how did you solve them
• in your report describe what is each of the make steps doing
• submit the report by e-mail together with the rest of the homework and attach files you modified. Don't forget:
  /tmp/listing_lab5
  /usr/src/linux/.config
  /boot/grub/menu.lst
  /etc/ssh/ssh_config
  /etc/syslog.conf.orig
  /etc/syslog.conf
