I wanted to have an idea about what should be the suggested range of
password lengths and if there is any upper bound.
I was told that there is a range upto which your password is
encrypted and beyond which the characters are futile. I work on a linux
environment with md5 encryption of passwords enabled.

From: "Michael LaSalvia" <mike () genxweb net>
Many people say 8 or more but I have read some where that multiples
of 7 are the best to use. It may have been in a class or something I
heard that.

If you were using the old DES encrypted ones exactly eight characters is best, for md5 anything reasonably complex should be fine. You want passwords to be as memorable as possible, their complexity should be in direct relation to how long people are allowed to keep them.
