Well, how often does the system crash if you just leave it alone in runlevel 5? It sounds like it's a few times an hour. If so, just leave it for three hours, and use the uptime command to make sure it hasn't crashed and rebooted. I would have suggested something like [james@kendrick tmp]$ dd if=/dev/urandom of=testcase bs=1M count=10 10+0 records in 10+0 records out 10485760 bytes (10 MB) copied, 3.32386 seconds, 3.2 MB/s to generate a 10 MB test case, [james@kendrick tmp]$ bzip2 -k testcase to bzip2 it (the -k keeps the original), [james@kendrick tmp]$ bzcat testcase.bz2 > testcase2 [james@kendrick tmp]$ cmp testcase testcase2 to uncompress it to a different file, and to check that the result is the same as the original. This ought to exercise the kernel, the processor, and memory. If you use a large enough testcase, it will exercise disk, as well. Or, if you've got space, you could just tar jcf ~/usr.tar.bz2 /usr to tar up the contents of /usr. Hope this helps, James.
Ah, I see what you're up to. I'll put the machine to work and see what it does. If it crashes, in what logs should I look? I've already peaked into most of what's in /var/log but didn't see anything that looked like a crash report. But as that's the first time I've ever looked at those logs, I could be wrong. I'm not familiar with them. Dotan Cohen http://what-is-what.com 33
