Re: [CentOS] Routing issue between 2 LANs
Hello Jose, from the picture you provided the situation looks pretty simple. - you have enabled IP forwarding on router, I recommend you to put it into /etc/sysctl.conf for persistence. - you have configured firewall rules on router to allow forwarding traffic from left to right subnet. You can also try to set up ACCEPT policy just for testing. - the default gateway for left subnet is 192.168.1.1 (you mentioned router for Internet access). Correct me if I'm wrong. - the default gateway for right subnet I assume is 192.168.236.74. You don't have to do anything with routing here. Every host in right subnet knows where to send replies. - the problem seems to be missing routing information in left subnet. Hosts don't know anything about the right subnet and thus send requests to the default gateway 192.168.1.1. - modifying routing table on every host in left subnet can be solution in case, if there is only a few hosts which need to access right subnet - if you need to have fully accessible subnets, put the static route to default gateway 192.168.1.1 to redirect requests to proper gateway. If it is Linux gateway, try something like this [r...@default-gw]# ip route add 192.168.236.0/24 via 192.168.236.74 Regards Andrej Jose Maria Terry Jimenez wrote: I have a CentOS 5.5 machine with 2 nics each one configured to work in one of the nets.

[CentOS] sysctl and gnome desktop
Hi all, I use CentOS 5.5 x86_64 on my laptop. I have couple of entries in /etc/sysctl.conf entries according to the recommendations http://www.lesswatts.org/projects/powertop/ When Gnome Desktop starts something resets them to defaults. For example 'vm.dirty_writeback_centisecs = 1500' resets back to 30. Does anybody have any idea how to workaround this? Thanks. Andrej. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] rsyslog as default syslog daemon?
James Pearson wrote: I think your problem is that you did 'chkconfig --del syslog' - as the man page states: --del name The service is removed from chkconfig management, and any sym- bolic links in /etc/rc[0-6].d which pertain to it are removed. Note that future package installs for this service may run chk- config --add, which will re-add such links. To disable a ser- vice, run chkconfig name off. I believe you should have done 'chkconfig syslog off' instead. We use rsyslog instead of sysklogd and don't get this problem. Thank you James, you are right, 'chkconfig syslog off; chkconfig rsyslog on' solved this problem. Andrej ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] rsyslog as default syslog daemon?
Hi all!
Is anybody here using rsyslog? I am looking for the right solution how
to use rsyslog in CentOS 5 as the default logging daemon. We use it
because of filtering using regular expressions.
I switched from sysklogd to rsyslog simply using
chkconfig --del syslog
chkconfig --add rsyslog
chkconfig rsyslog on
service syslog stop
service rsyslog start
but this seems not to be bullet-proof solution - when yum automaticaly
install updates, sysklogd rpm package runs postinstall scriptlet which
unfortunately returns sysklogd back to game (and breaks logging based on
regex).
# rpm -q --scripts sysklogd
postinstall scriptlet (using /bin/sh):
if [ $1 -ge 1 ]; then
/sbin/chkconfig --add syslogHERE
for n in /var/log/{messages,secure,maillog,spooler}
do
[ -f $n ] continue
touch $n
chmod 600 $n
done
/sbin/service syslog condrestart /dev/null 21
fi
exit 0
...
# chkconfig --list syslog
syslog 0:off 1:off 2:on3:on4:on5:on6:off
Meanwhile, automatic update of rsyslog package results (thanks to
postinstall scriptlet) into disabled rsyslog :-/ ...
# rpm -q --scripts rsyslog
postinstall scriptlet (using /bin/sh):
/sbin/chkconfig --add rsyslog HERE
for n in /var/log/{messages,secure,maillog,spooler}
do
[ -f $n ] continue
umask 066 touch $n
done
...
# chkconfig --list rsyslog
rsyslog 0:off 1:off 2:off 3:off 4:off 5:off 6:off
- uninstalling sysklogd package will not solve the problem of disabling
rsyslog after yum update. Or should I uninstall it and simply change '#
chkconfig:' part of rsyslog rc script?
- I don't want to disable automatic updates of sysklogd and rsyslog
packages using /etc/yum.conf:exclude=... bacause of security reasons.
- I think about using 'alternatives', but I am not sure if it is the
appropriate solution.
- should I report to Red Hat's bugzilla?
Maybe I overlooked something in documentation.
Thank you for any advice and patience.
Andrej

Re: [CentOS] Firefox slower on GMail since update to CentOS 5.5

[CentOS] xorg and backlight
Hi all, I have found one problem after upgrading to CentOS 5.2 x86 on my HP Compaq nx7010 laptop. When I close and open lid, backlight is not turned on again. I can see my desktop, but the only thing I can do is press CTRL+ALT+BACKSPACE to restart X11. Then the backlight is restored. xorg.conf is generic, created by installation process. I use ATI proprietary driver 8.28.08 (the last which support Mobility Radeon 9200). I would appreciate any hint or help.
