Verifying the Debugging Tools

Verifying the Debugging Tools

After performing the preceding steps, restart the system. Messages from sash appear on the attached terminal, rather than on the graphics screen. If symmon is present, it announces itself on the console terminal also.

To verify operation of idbg, issue the idbg command and display the process list:

# idbg
idbg> plist
active process list:
34:672:"xdm" pri(60) SLEEP flags: load uload siglck recalc sv 
0:0:"sched" ndpri(39) SLEEP flags: sys nwake load uload sv 
31:193:"inetd" pri(60) SLEEP flags: load uload siglck recalc sv 
...

To verify operation of symmon, press control-A at the console terminal. The prompt string DBG: should appear. At this time the system is frozen and no longer responds to mouse or keyboard input. Type the letter c (for continue) and press return. The system returns to life.
