How can I free the disk space after compiling kernel
by Ian jonhson 16 Oct '08

16 Oct '08

Hi, I have recompiled my kernel and updated it to kernel-2.6.27. However, I found there are no more than 1G disk space left for my jobs. How can I free my disk space but in the same time keep all the compiled kernel modules (*.ko files) here? Can I remove the *.o files created by kernel compiling? Are there any commands to help me achieve this? Thanks a lot, Ian

formatting large volume
by Craig White 16 Oct '08

16 Oct '08

I just got a new server with a Dell MD-1000 SAS unit and 6-750 gigabyte drives which are now initializing in RAID 10 which will give me just about 2 terabytes. I vaguely recall reading that fdisk wasn't suitable for partitioning and wonder if I shouldn't be using partd instead. I am also wondering if I should use lvm or just mkfs to create the filesystem. Anyone have suggestions before I blunder in? Thanks Craig

[OT] What is the best network monitoring tool?
by Alejandro 16 Oct '08

16 Oct '08

Hi all, Currently I have a big question. What is the best OPEN SOURCE solution for monitoring multiple Host and Services, for example for using in a WebHosting Provider with 50 hosts or more. Currently, I'm using NAGIOS for more than 3 years, this is a incredible tool, but before upgrade to version 3, I have this existential question. Please fill free to recommend any soft, but with this option in mind. 1- Easy option to personalize any plug-in 2- Good Documentation 3- Support large platforms 4- Run over Linux Sorry for me English Regards Alejandro www.linuxiso.com.ar from Buenos Aires, Argentina

OT: is parted reliable?
by Sergio Belkin 15 Oct '08

15 Oct '08

Hi, I've read on LPI Linux Certification (Ed O'Reilly) in a nutshell the following thing: "parted, unfortunately, has been known to corrupt partition tables and ruin filesystem." What do you think about it? Greets! -- -- Open Kairos http://www.openkairos.com Watch More TV http://sebelk.blogspot.com Sergio Belkin -

Problem building Perl net-snmp
by Marcelo M. Garcia 15 Oct '08

15 Oct '08

Hi I'm trying to build the perl modules of net-snmp-5.4.2. Everything seems to work fine until "make test"[1]. The problem with "DynaLoader.pm" seems to be an old one. The machine is Centos 5.2 i386 I'm trying to build instead of using the one available in the repos because I'll build in other platforms and also in nagios-plugins. Thanks Marcelo [1] Failed 17/17 tests, 0.00% okay t/getnext.....Can't load '/users/newt2/mgarcia/Downloads/Nagios-3.0.3/net-snmp-5.4.2/perl/SNMP/../blib/arch/auto/NetSNMP/default_store/default_store.so' for module NetSNMP::default_store: libnetsnmp.so.15: cannot open shared object file: No such file or directory at /usr/lib/perl5/5.8.8/i386-linux-thread-multi/DynaLoader.pm line 230. at /users/newt2/mgarcia/Downloads/Nagios-3.0.3/net-snmp-5.4.2/perl/SNMP/../blib/lib/SNMP.pm line 16 Compilation failed in require at /users/newt2/mgarcia/Downloads/Nagios-3.0.3/net-snmp-5.4.2/perl/SNMP/../blib/lib/SNMP.pm line 16.

Mass installs of desktop systems on identical machines
by Niki Kovacs 15 Oct '08

15 Oct '08

Hi, I'm running a small Linux consulting business here in a group of small villages in the South of France (http://www.microlinux.fr) I'm using CentOS for everything, servers as well as desktops. The desktop installs are usually highly customized. My approach is to list the client's needs, find the corresponding applications and then install these, to avoid the bloat and increase usability. So far, this approach worked quite well. One complete install and configuration takes about 4 hours, depending on various factors such as bandwidth (internet is not very fast in our remote places here) and sometimes exotic hardware that is tricky to configure. Yesterday I had a conversation with the boss of a computer store in town. One of his standard PC models (desktop) is an ACER (PIV dual core, 3 GB RAM, 320 GB HD, ATI card) shipped with Windows Vista, and sold for a price of 315 euros. He told me he would be very interested to sell these machines with Linux installed, as this would allow him to lower the price. Now I wonder: 1) Say I want to install my own customized version of CentOS on it, I usually charge a fixed amount of 240 euros for installing and configuring a complete desktop, tailored to the customer's needs (average: 4 hours of work = 60 euros / h). But I think that this is not what's expected here (neither the price nor the amount of work). How would it *technically* be possible to replicate these installs as easily as possible? The hardware is always the same, so I wonder: I have a vague idea about disk images (to be more precise: I know disk images well as far as burning CDs on the commandline is concerned, or when it comes to installing an OS in VirtualBox using the .iso)... but is there a way to somehow transform an existing install into a disk image, and then simply copy these over to all the other machines? (I've never done this) 2) Otherwise, go for a more mass-oriented distro like Ubuntu, Mint or the likes? What speaks for it: they can be installed very easily, insert the CD or the DVD, fill in the form (username, password, hostname, there you go). On the other hand, I've always been careful about picking my applications in a "best of the breed" way, and I would feel like a traditional taylor working for C & A. 3) Let's not forget about the users who are going to buy this. Whereas folks can always be expected (more or less) to "administrate" their own Ubuntu install, this looks less obvious with CentOS. Or let's say: forums.centos.org is not exactly a newbie forum, at least compared to Ubuntu. I guess your average newbie will not be very pleased with the prevailing tone of competent techno-laconism (compared to Ubuntu or the likes). I'd be curious to read your suggestions about this. Cheers, Niki
