similar to: make rpm for kernel

WE have a centos 5.3 install, and our server is keep getting hacked. We see load averages of 500+ and see people from all over the world logging into our server (used last). Is there a good place to start to avoid these kinds of things? For example, here is what I already did. Open up sshd port only setup iptables to only accept port 80 and 22 No FTP No other ports are allowed according to IP

We use Microsoft Outlook heavy at school but our backed is CentOS. I use echo "Foo" | mail -s "subject" addr at unc.edu a lot. Is it possible to change the priority to High so Outlook will understand it? The priority meaning the email will be sent to the normal email queue but on Outlook it would have the exclamation point. TIA

We have about 800 CentOS 5.2 servers and our university. We use NFS being served from over 10 NetApp frames. We use autofs for to mount up our partitions. There have been times where we can't cd into the directory. It says the directory does not exist. On some servers it works but on others it does not. Typically we restart amd and autofs to resolve this issue. But sometimes it does not even

Hello, I know centos does not use syslog-ng, but I have installed it at my university. My intention is if a particular string appears in my /var/log/messages I would like to get an email alert. For example, if i see a message "foo" in /var/log/kern I would like to email myself. Any idea how to do this? Has anyone done this before? TIA

Hello All: Running 5.2 at our university. We have several student's processes that take up too much memory. Our system have 64G of RAM and some processes take close to 32-48G of RAM. This is causing many problems for others. I was wondering if there is a way to restrict memory usage per process? If the process goes over 32G simply kill it. Any thoughts or ideas? TIA

I'm very confused on the right step to use to setup a modified kernel in centOS6. As a simple user, I've downloaded the latests sources (I'm runing an old kernel version) : rpm -i http://vault.centos.org/6.7/updates/Source/SPackages/kernel-2.6.32-573.22.1.el6.src.rpm in the spec file ~/rpmbuild/SPECS/kernel.spec I've set: %define buildid .numa Now I want to set

Hello All, I have been using rsync to backup several filesystems by using Mike Rubel's hard link method (http://www.mikerubel.org/computers/rsync_snapshots/). The problem is, I am backing up a lot of ASCII .log, csv, and .txt files. These files are large and can range anywhere from 1GB to 30GB. I was wondering if on the target side (the backup side), if I can use some sort of compression. I

Hi All, I am trying to understand the purpose of rsyncd. Why does it exist? Why not just use rsync ad-hoc or via script? Also, to a more serious note. I need to keep a filesystem on 1 server and another server synced by. What is the best way to do this? I want to have /source and /target to be exactly the same. I don't want any extra files in /target. I want the timestamps to be the exact

At our Physics research labs we do a lot with low latency networks. We have been using Centos for over 3 years now and its been great! We would like to tune and optimize our setup by removing unneeded packages -- kernel modules to be specific. I was wondering, how does one measure the speed of the kernel. Is that even possible?

I have 12 750GB drive appliance from HP. I was wondering what is the best disk configuration? I suppose a large RAID5 would be bad since rebuilding would take too long. What do you recommend?

and AJB kernel-2.6.35-3.bcat.src.rpm [I see AlanBartlett as the last editor on that page] I have installed the given ajb source rpm kernel-2.6.35-3.bcat.src.rpm, and verified that it is intact: [herrold at kernel-bleeder linux-2.6.35.i686]$ rpm -Vp ~/build/ajb/sources/kernel-2.6.35-3.bcat.src.rpm warning: /home/herrold/build/ajb/sources/kernel-2.6.35-3.bcat.src.rpm: Header V3 DSA signature:

As I plow through the Kernel source to figure out why the BEET patch is not working, I notice that there are two similar directories under ~/rpmbuild/BUILD/kernel-2.6.18: linux-2.16.18.i386 and linux-2.16.18.i686 So which one am I suppose to be patching? Currently, the patch starts out with: diff -urN a/net/ipv4/xfrm4_input.c b/net/ipv4/xfrm4_input.c I followed the kernel source setup

At my physics lab we have 30 servers with 1TB disk packs. I am in need of monitoring for disk failures. I have been reading about SMART and it seems it can help. However, I am not sure what to look for if a drive is about to fail. Any thoughts about this? Is anyone using this method to predetermine disk failures? TIA

I am planning to sign up for a VoIP service in the U.S. Can anyone recommend anything cheap, reliable and good quality? I want to use it for my primary house phone (I also own a cell phone). I also want the service to be asterisk friendly so I can play with it :-) Thanks in advance. -------------- next part -------------- An HTML attachment was scrubbed... URL:
