Can you tell us how you're making the bootable USB key? e.g. the source .iso file[s] and all commands used.

LUKS full disk Encryption question
by Ljubomir Ljubojevic 08 Jan '12

08 Jan '12

From RHEL docs: "The default implementation of LUKS in Red Hat Enterprise Linux is AES 128 with a SHA256 hashing. Ciphers that are available are: AES - Advanced Encryption Standard - FIPS PUB 197 Twofish (A 128-bit Block Cipher) Serpent cast5 - RFC 2144 cast6 - RFC 2612" My question is: What will be the performance impact on my Celeron 1.73 GHz CPU and/or hdd speed? -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe Google is the Mother, Google is the Father, and traceroute is your trusty Spiderman...

upgrade of 32bit to 64 bit CentOS 5.7
by Rob Kampen 08 Jan '12

08 Jan '12

Hi List, Early in dec I was forced to upgrade one of my server systems - initially built in 2004 on an intel server mb it finally failed. Under some time pressure, I replaced the mb etc with a 64 bit asus system and did a repair of the linux system upon reboot with a 64 bit DVD. As one can imagine there were some headaches as the kernel was now 64 bit, but yum and friends were still 32 bit. I managed to upgrade the required packages to 64 bit, rebooted the server a few times and all appeared to function ok. BTW the server runs bind, apache, postfix, dovecot, mysql, php and related stuff. I have now relocated the server in a lights off situation and myself to the other side of the planet. Why all the history - well as I ssh into the box and do my weekly yum updates, I find that there have been no updates, however all my other servers have had multiple updates. Thus I did a rpm -qa and find there are only 65 rpm files listed - they are all 64 bit or noarch - none of the core server files are present. How do I systematically update all the files from 32 bit to 64 bit? As I am unable to physically get in front of this machine, I have zero room for error - and need the machine to be up and operating each business day. My google searches have not given me any hits that help. Any help, directions, things to be aware off etc - appreciated. TIA

With all of the discussions regarding getting p3wned, I am feeling paranoid and can't seem to figure out how to suppress this... telnet $SOME_CENTOS_5_SERVER 22 Trying $SOME_IP_ADDRESS... Connected to $SOME_CENTOS_5_SERVER. Escape character is '^]'. SSH-2.0-OpenSSH_4.3 'Banner no' doesn't do it. Is it possible to suppress the version? -- Craig White ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ craig.white(a)ttiltd.com 1.800.869.6908 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ www.ttiassessments.com Need help communicating between generations at work to achieve your desired success?

Advice sought: Virtual Win7 on Centos 6.2
by david 07 Jan '12

07 Jan '12

Folks I have a new laptop running Centos 6.2 64-bit. I'd like to put a virtual machine running Windows 7 (licensed), with full audio/video functions, and good response. Which virtual system would you recommend? I can think of KVM, or VirtualBox, or ...? The "good response" requirement pretty much excludes a web-style video presentation. Opinions solicited.

fcron scheduler
by Kaushal Shriyan 07 Jan '12

07 Jan '12

Hi, Is fcron scheduler available in CentOS 5.6 Server ? I did yum search fcron and it does not return anything. As per http://fcron.free.fr/description.php Fcron is a scheduler. It *aims at replacing Vixie Cron*, so it implements most of its functionalities. But contrary to Vixie Cron, fcron *does not need your system to be up 7 days a week, 24 hours a day* : it also works well with systems which are not running neither all the time nor regularly (contrary to anacrontab). In other words, fcron does both the job of Vixie Cron and anacron, but does even more and better :)) ... Any clue, Regards, Kaushal
