Yep. Change the values in /etc/login.defs for PASS_* and use: chage -M <value> -m <value> -W <value> USER -- During times of universal deceit, telling the truth becomes a revolutionary act.

If I have a good, strong password that nobody knows, how is changing it to another one an improvement over what I already have? << Correct. Modern thinking is to teach people how to create a good, strong password and then stick with it for a longer period than has traditionally been the case. A rainbow tables attack against a captured hash can be done in just a few seconds, so unless you're prepared to change your password every few seconds, it's a futile gesture. Because most sets of rainbow tables cover all combinations of upper/lower case alpha, numeric and punctuation symbols, a strong password should contain at least one control character, a composed character (using the Alt+numpad technique) or some other non-printable character outside the rainbow tables set. Or use two-factor authentication (RSA SecurID or similar tokens, certificates, etc.). Best, --- Les Bell, RHCE, CISSP [http://www.lesbell.com.au] Tel: +61 2 9451 1144 FreeWorldDialup: 800909

question on "cp -f" on centos 5.1
by Jerry Geis 29 Jan '08

29 Jan '08

When I issue the command cp -af --reply=yes * ../other it tells me --reply is deprecated and use -i or -f. when I remove the --reply=yes I have to indicate 'y' to every file being copied. I just want to copy every file in my current directory to another directory and overwrite any file that is there. What is the correct way to do that? Jerry

boot slow at "Applying ip6tables firewall rules"
by Dan Halbert 28 Jan '08

28 Jan '08

I have a fairly vanilla install of Centos5 on a desktop box (with a Broadcom NetXtreme BCM5752 Gigabit NIC). When booting, the boot process hangs at "Applying ip6tables firewall rules" for 30-60 seconds before proceeding, which is annoying. I have not tried to turn off ipv6 networking. I guess I could, but is this slowness to be expected? Is it waiting for some ipv6 response? Thanks, Dan

EDAC error
by Dianne Yumul 28 Jan '08

28 Jan '08

Hello, I upgraded to CentOS 5.1 and everything went smoothly (Thanks for the awesome work!). But after rebooting, I get the following error: EDAC MC: Ver: 2.0.1 Nov 30 2007 EDAC e7xxx: error reporting device not found:vendor 8086 device 0x2541 (broken BIOS?) I found http://edacbugs.buttersideup.com/show_bug.cgi?id=21 with google but no solution. Is it safe to ignore the error or remove the EDAC module? I read their wiki but I'm new to this and I don't want to break anything? Please advice on what to do next? Thank you so much. dianne
