RE: [CentOS] Backing up CentOS

Something I forgot to mention about the backupexec agent. Depending on how restrictive your iptables firewall is (mine denies all in/outbound connections by default then I layer what is needed using fwbuilder) your going to need to make corrections for the agent to 'advertise' itself to the backupexec system and then create rules to allow the server to tell the agent to start the backup/restore. -greg > -----Original Message----- > From: centos-bounces(a)centos.org > [mailto:centos-bounces@centos.org] On Behalf Of Chris Peikert > Sent: Tuesday, April 18, 2006 1:43 PM > To: 'CentOS mailing list' > Subject: RE: [CentOS] Backing up CentOS > > Thanks.

small issue with bind
by Jerry Geis 18 Apr '06

18 Apr '06

I tried to do a "yum install bind" and it said no packages found I then tried up2date bind and it installed bind for me. Is yum not completely setup correctly? Just thought th yum install bind would have worked also. I am using centos 4.3 x86_64. DNS was not selected as package to install when my system was built. Jerry

Centos as a network recorder and request
by King, John (Greg) (LMIT-HOU) 18 Apr '06

18 Apr '06

I am looking at using CentOS to use as a network recorder to enhance our security analysis. During my research I found that the linux kernel (not CentOS specific) has a bad problem of dropping packets on gigabit connections. This problem exists even on a dual xeon system with 1gb ram using a minimal install. Once I found the ethereal performance wiki I realized the problem was not in the system but in the manner in which packets are moved from the kernel to userland. http://wiki.ethereal.com/Performance The only solution I can find to address this is a kernel patch called pf_ring http://www.ntop.org/PF_RING.html I would prefer to not recompile the kernel and instead stay with the supportable baseline provided by centos. But, in order to reduce dropped packets, having pf_ring compiled into the kernel appears to be my only solution unless someone here knows another way they want to share. I did some mailling list and forum archive research on recompiling the kernel and followed (for awhile) the 'newbie kernel question' thread in hopes of finding some answers on how to do this using the centos sources without going to kernel.org. >From what I gather recompiling is not recommended (understandable from a support viewpoint) so is there enough interest from the CentOS community (and from the CentOS team) to request this to be added, maybe as a separate branch like the 64bit iso's? If not, again understandable as that would be yet 1 more branch to support, then would someone please provide link/links to more information on recompiling the centos kernel.src.rpm? Googling I found all kinds of information but it either dealt with the 2.4 branch, 2.6 when it was still in testing (digital hermit), involved other distros (Installing PF_RING and nProbe on Fedora Core 4), or was for stock RedHat Enterprise and although CentOS uses the src.rpms from RedHat, I do not want to assume the compile process is the same and end up shooting myself in the foot. Having a process that can be followed for CentOS 4.3 to add functionality to the stock kernel would be a great edition for people like me who have had no need in the past to recompile the kernel or roll-their-own (yeah I looked at linux from scratch too as an option). As a side note, based on some of the previous threads involving centos 4.3 and compiling kernels my timing for this post is probably not the best. It is not my intention to start more arguing but to simply pose my current problem and seek assistance from the CentOS community for a solution. Thanks, Greg

kernel source 2.6.9-34.EL 4.3
by Peter van Eck 18 Apr '06

18 Apr '06

Hi, I've hit an unpatched kernel issue while trying to build on sources see the header for version details.. arch/i386/kernel/built-in.o(.init.text+0x1585): In function `setup_arch': : undefined reference to `acpi_boot_table_init' make: *** [.tmp_vmlinux1] Error 1 It seems that I would need to install (centos/redhat) patches after installing/building the kernel source tree from the kernel-2.6.9-34.EL.src.rpm Is that correct ?? thanks, Peter

rpm build difference?
by Akop Pogosian 18 Apr '06

18 Apr '06

I noticed a strange thing on my CentOS 4 workstations today. Immediately after installing the tetex suite (tetex-xdvi tetex-dvips tetex tetex-latex tetex-afm tetex-fonts), "rpm -V tetex" reports some package inconsistencies: rpm -V tetex ........C /usr/bin/amstex ........C /usr/bin/bamstex ........C /usr/bin/bplain ........C /usr/bin/lambda ........C /usr/share/texmf/web2c/amstex.fmt ........C /usr/share/texmf/web2c/bamstex.fmt ........C /usr/share/texmf/web2c/bplain.fmt ........C /usr/share/texmf/web2c/cont-en.efmt etc.. After investigating, it appears that these files belong to tetex and rpm -V inconsistencies appear only after I also install tetex-latex. The strange thing about it is that I can't find the definition of "C" in the rpm manual page. Moreover, the entire field where C is printed on CentOS is not printed on RHEL4. I tried looking at the differences in the source RPMs for RHEL 4 and CentOS 4 but couldn't find anything. Any thoughts on the rpm issue? -akop

Since you mentioned BackupExec, I use the backup exec linux agent and it works fine and ties into our centralized backup system for our windows,linux and unix systems. I used to use Mondo Archive (I was going to provide a link but their site is unavailable now...) to create automated cd restore images on a weekly basis. I could then quickly recover via ISO images and then would restore the incremental changes via backup exec. I am using another commercial product now though for the images. -greg > -----Original Message----- > From: centos-bounces(a)centos.org > [mailto:centos-bounces@centos.org] On Behalf Of Chris Peikert > Sent: Tuesday, April 18, 2006 8:08 AM > To: 'CentOS mailing list' > Subject: RE: [CentOS] Backing up CentOS > > Well the idea is if I can get my CentOS box to communicate > with my Windows > 2003 network I was going to do a backup and put the backup > file on a windows > box where I would have Backup Exec put it on Tape.
