You can go to a console, ctrl alt F1, and login then type passwd. That will let you change the password to something else. There is a config file somewhere that you can change so that it won't expire. I can't recall which one it is though.
If you can not login, because you have expired, you may have to boot in single user mode. If you use grub, it is pretty easy. Reboot, when grub comes up, highlight the Linux boot like you are going to boot Linux and hit e twice. Add single to the end of the line. Note, there is no network or anything here. This is a bare, really bare, boot up. Not much of anything works when you boot this way. You will not have to login though. You go straight to a text prompt, no GUI either.
When you get to that prompt, type in passwd, then enter your new password twice. If you get no errors, type in reboot. You may want to type in init 5. That should be the same as a regular boot.
You may have a boot line called failsafe. You may can boot to that and this work as well. Not real sure, depends on how Redhat set it up to boot.
On the penguin with the ? mark. You need to talk to Jeremy about that. http://www.linuxquestions.org/questi...ssage&userid=1
Jeremy's a OK guy but if he made it, he may want to keep it. Not real sure. Sort of depends on where he got.
You may try a www.google.com/image
and see if it is public or copyrighted. If it is copyrighted, don't use it. There are people that look for those things ya know. Not worth getting in trouble over.
Hope that helps. If you use lilo, sorry. I don't know how to fix. There likely is a way, I'm just a grub user is all.
