Checkpoint log analyzer / network analysis tools
by Benjamin J. Weiss 25 Apr '06

25 Apr '06

All, I'm looking for tools available for linux that will allow us to do two things: 1) Analyze our Checkpoint Firewall-1 NG log files and provide reports / graphs / pretty management pictures. 2) Analyze our network traffic (Cisco routers and HP switches) and provide reports / graphs / pretty management pictures. I've implemented ntop, which is pretty cool, and I'm looking at mrtg. Anybody else using anything else? Thanks! Ben

Preventing the nightly backup from disturbing the cache
by Steve Bergman 24 Apr '06

24 Apr '06

Hi all, I have a server with 4GB of memory and a workload that allows it to work mostly from memory without a lot in the way of disk reads. However, every night the backup distrurbs that situation by reading every file on the system. Is there a way to prevent this from happening? I'd like to be able to tell the kernel, hey this program is going to be reading a bunch of files serially, so please don't cache the data. Is that possible? Thanks, Steve

Installing DNS
by Kaplan, Andrew H. 24 Apr '06

24 Apr '06

Hi there - I need to install a DNS server on one of our systems running version 4.1. The server itself does not have a CD-ROM drive, so I am going to mount the media on a remote system and extract the files that I need from that location. My question is, what packages do I need to install to properly set up the DNS server? Thanks.

Permissive SELinux hangs some services
by Kai Schaetzl 24 Apr '06

24 Apr '06

SELinux is set to permissive mode and warns on startup of a service (during boot-up): Warning! Could not relabel /dev/pts/0 with user_u:object_r:initrc_devpts_t, not relabeling.Operation not permitted So far, so good. But this logging let's this application and all that should start after it hang. ps then shows: initlog -q -c /etc/rc3.d/S98bigsister start (bigsister is a monitoring agent) if I wait long enough the above warning gets written to messages and startup of that daemon succeeds. However, the other daemons after it don't start. If I kill the initlog process fast enough the other daemons start, nothing gets logged and the bigsister service fails to start. syslog is clearly started and working at that time. If I set SELINUX=disabled the startup process runs like normal. So it's clearly that SELinux logging (or something else in regard to SELinux, although disabled) that makes this fail. This shouldn't happen, shouldn't it? Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

CentOS 4.3 apt repo
by Ralph Alvy 23 Apr '06

23 Apr '06

I asked this before when I configured another CentOS box, but I forget the answer. In my apt sources folder, I don't have a repo that is the equivalent of the yum Centos.Base.repo. Where do I find such a file?

Xen on CentOS 4.3
by Kanwar Ranbir Sandhu 23 Apr '06

23 Apr '06

Hello, Has anyone set up Xen on an existing CentOS 4.3 system? Does it work well, or is it better to wipe the system and start clean? I haven't found a lot of information about this specifically. Secondly, I have found on the xen source website downloads for xen 3.02, which are meant for FC4 or RHEL (U1). I'm tempted to try the RHEL downloads, but I don't have any spare machines to test on, so I'd have to do it to a live system (!). Even though the xen download is for RHEL U1, will it work on RHEL U3/CentOS 4.3 machine? Has anyone tried this? I'm anxious to consolidate three of my servers onto one under used machine because one of the three is going to suffer a HD failure soon (it's locking up every now and then, and I hear the HD making clicking noises!). Thanks in advance for any tips or comments. Regards, Ranbir -- Kanwar Ranbir Sandhu Linux 2.6.16-1.2069_FC4 i686 GNU/Linux 14:06:42 up 7:36, 2 users, load average: 0.86, 0.52, 0.21

Which is the difference between dirty and clean state? Both systems work fine.

kickstart
by Kevin Blackwell 23 Apr '06

23 Apr '06

Hello, I've been trying to kickstart a install centos from a USB memory stick. Everything with that is working fine, but I seem to be having a problem with the ks.cfg file. When I boot the install media from the usb drive, the the boot prompt I type linux ks=hd:/dev/uba1/ks.cfg Then I peek at the logs and it even says * getting kickstart file * getting kickstart file from harddrive * Loading ks from device on path dev/uba1/ks.cfg * getFileFromBlockDevice(, dev/uba1/ks.cfg) But when the install script starts, it still ask me for install media location. Here's a copy of my ks.cfg too.. Permissions of the file on /dev/uba1 are 744.
