prerotate
/etc/init.d/denyhosts stop

postrotate

But this causes errors

error: denyhosts:2 unexpected text
error: denyhosts:3 unexpected text

I appreciate any help on this.
Many thanks,

Yes, that's fine - logrotate supports that.
Please hash out all the lines in the denyhosts rotate file and run
logrotate -d /etc/logrotate.conf

[gentoo-user] Is this a bug of runscript? (status will not turn to started)
hi, all, i had write a #!/sbin/runscript script, but status will not turn to

THX all of you.
source code first (i want to start a bash script with runscript):
+---
|#!/sbin/runscript
|#file name: test
|.in start() {
|start-stop-daemon -S -p ${PIDFILE} -m -b -a ${EXECFILE} --

sudo ./test start
* Starting Test ... [ ok ]
sudo ./test start
* Starting Test ...
process already running.
sudo ./test stop
* WARNING: test has not yet been started.
sudo ./test status
* status: stopped
but the bash script is running, and the $PIDFILE had filled with correct pid
number, so ,i can;t stop it with runscript.
in another way to write this script, but use bash this time, it totaly OK.

[gentoo-user] Gentoo decapitated
About a week ago, my Gentoo box was in a bad state where there were some packages that would not install, so I was carefully emerging what I could and filed a bug about one in particular that I could not emerge. Then I got a new kernel, 2.6.32-gentoo-r7, and I booted from it. Eeeek. No X11 at all. The logs informed me about some things to do, and I did them, re-emerging a number of things. I paid particular attention to emerging anything with x11 or xorg in its name. Long wait. I got to a point somewhere in there where X11 started, but would recognize neither keyboard nor mouse. I kept going. The keyboard started to work. I could actually log in, but that's not all that useful without a mouse. Then I started getting complaints about USE flags needed to make some particular packages support some other packages. I did those too. Now I'm at the state where emerge -aDNvu denies there's any work to do, and revdep-rebuild reports health. Still no mouse. Fortunately, I have a laptop that can ssh into the box and I can work with it, but it's still essentially headless. Anybody run into this state recently?
