Latest CVS - still invalid timestamps on Alpha Linux


From: Vladimir Strezhnev <vlast () eetc com>
Date: Thu, 5 Jul 2001 17:06:55 -0500

PLATFORM:
Ruffian Alpha (by DeskStation Technologies)
RedHat 6.2 (2.2.16-3)
Snort-1.8-beta9 (and all previous)

PROBLEM:
Random dates and invalid years (with -y option) in log files on Alpha 
platform.

DESCRIPTION:
Following is selected log entries produced by testing with Nessus. All 
entries were collected on July 5, after 4pm within several seconds' span:

Here is the output of hwclock --debug
run on the Alpha host.

hwclock 2.13
User did not specific a clock access method.  Searching for one...
Not selecting rtc method because:  Found file /dev/rtc, but The device 
special file '/dev/rtc' exists, but the device driver for it is
not in your kernel (and the kerneld service did not load it either.  See the 
Hwclock man page (section "Linux rtc device driver ") for details.

hwclock was built for a kernel without KDHWCLK capability (according to the 
kernel's kd.h header file), and the KDGHWCLK ioctl() doesn't work either.
Using direct I/O instructions to ISA clock.
