Setting up altq-delay src 
=========================

** Note: I'm using ~/gpstcp as my /usr/src directory.  So, if you are
** really installing src, use /usr/src instead of ~/gpstcp.

* If there's a sys-altq_noCompile.tgz file on tyagi, skip to step 5.

1. tar up /usr/src/sys-altq on tyagi (as root)
tyagi# cd /usr/src/
tyagi# tar -czvf sys-altq.tgz sys-altq/*

2. ftp sys-altq.tgz AND /usr/src/delaybox/delay_box.patch to your
   machine of choice

3. untar sys-altq.tgz in your directory of choice

4. remove everything _under_ the compile directory 
   (but NOT the compile directory itself)
bennett# cd ~/gpstcp/sys-altq/compile
bennett# rm -rf *

5. copy COMP290 conf files from the altq src on bennett   
  (FOR 290 machines only)
bennett# cd ~/gpstcp/sys-altq/i386/conf
bennett# cp /usr/src/sys-altq/i386/conf/COMP290* .

6. make a copy of the sys-altq src in the sys-altq-delay dir
bennett# mkdir sys-alt-delay; cp -r sys-altq/* sys-altq-delay

7. apply the delaybox patch  
   (In general look at /usr/src/delaybox/INSTALL on tyagi.)

	7.1 Applying the patch to the kernel source tree and make a
	new kernel.

        Apply delay_box.patch to the kernel source
        # cd ~/gpstcp/sys-altq-delay
        # patch -p < ../delay_box.patch >& ../patch.out

	7.2 Notes on how this patch was created in case you want to
	create your own patches in the future:  

	  On a machine that has a /usr/src/sys-altq tree and a
	  /usr/src/sys-altq-delay:

          # cd /usr/src/sys-altq-delay
          # diff -urN ../sys-altq . > ../delay_box.patch
        
8. examine patch.out for problems.  You may want to especially pay
   attention to the config files in i386/conf.  Make necessary changes
   by hand (hopefully none).

9. config ALTQ.1000 and compile.  
   (NOTE: delaybox only works with 1000 HZ kernels.)

     # cd i386/conf
     # config ALTQ.1000
     # cd ../../compile/ALTQ.1000
     # make depend
     # make

    (NOTE: for COMP290, we'll ftp the src to krishnan and cp to / there.)
     # su root
     # cp ALTQ.1000 / 
     # shutdown -r now
