lol. Uses Redhat and posts question about it in Dawmsmalllinux forum.

As to your question about your health, check the logs in /var/log. That should let you know if something needs attention, unless something stops working. Still a good place to look though. Generally with Linux, if it works and is secure, you're set to go. Some Linux OSs, Redhat for sure, can run for weeks, months, even years with no need to reboot. Hardware seems to be the biggest reason for rebooting. That is really true for me. I'm compiling Gentoo for another system as I type.

As I tell a friend of mine, if it works and is stable, leave it be, it's working. If something is wrong, it will let you know. If you are on DSL or some other broadband, make sure you are secure. Check the ssh logs to see if someone if trying to get access to your rig. I have been reading about people finding those lately using the user accounts, guest, test and even root. GOOD passwords are the best way to keep them at arms length.

Post if you need more info. I'm sure someone will post their thoughts as well.

Later

Type in top for cpu, memory etc. Hit the q key to quit. For the hard drive, df /dev/hd**. A example would be df /dev/hdb1 for second drive first partition.

There are also some programs that are GUI based that do the same thing. Just depends on what you want to use.

That help any?
