When I was a system administrator, there was a command to find out how much real memory was on your system, logged in as root (making sure you didn't confuse the input and output!): dd if=/dev/mem of=/dev/null bs=1024 conv=noerror It would chug away for a minute or two, then give you a number of records in and out, this number was how many KB or RAM you had; I tried this on debian, now all I get is a string of error messages... Is there a better way???
