iproute2 custom tables and rules the CentOS way...
by Ray Van Dolson 24 Jan '11

24 Jan '11

Hi all; I have a custom iproute2 table and a few rules to go along with it (CentOS 5) -- I have added the table to /etc/iproute2/rt_tables. if-up and friends doesn't seem to handle this real gracefully. How are those of you out there doing something similar managing this customization? I don't really want to muck with /etc/init.d/network or the if-up scripts to avoid breaking upgrades. rc.local my best bet? Thanks, Ray

putting "/tmp" to memory
by kellyremo 24 Jan '11

24 Jan '11

"to memory" means: mounting a ~2 GByte filesystem [ tmpfs?, or ramfs? ], and put the "/tmp" on it. [ e.g.: 4 GByte ram in the pc ]. what to write in the "/etc/fstab"? I would like to collect the [ answers too:P ]: Advantages: - Memory is way faster then HDD/SSD, so it could speed things up - "SSD amortization" is less Disadvantages: - Security? [ how to set this up to be secure? any clear howtos/links regarding it? :O ] Really thank you for any good help...

Why don't you download the DVD, it give you much more than disc 1. >>> Parshwa Murdia 01/19/11 1:41 PM >>> Hi, I have downloaded the following version: CentOS-5.5-i386-LiveCD-Release2.iso from the mirror: http://ftp.iitm.ac.in/centos/5.5/isos/i386/ What I want to ask is that 'Release2' is the complete OS and after installation we can use 'yum update'.

Rudi, this is an explanation of *why* it's frowned on, and a link to the std. nettiquitte FAQ. If you think this is a flame, you've never seen a *real* flame.

curious reboot output
by Tim Dunphy 24 Jan '11

24 Jan '11

Hello list! I was just curious about the output of a command I typed. [root@LCENT02:~] #last reboot | head -1 reboot system boot 2.6.18-194.26.1. Wed Dec 29 20:03 (24+01:33) This is odd because this machine was rebuilt today (Saturday 1/22) in mid afternoon. Just curious how the output of this command could NOT know this? Also I notice that on select machines the command init 6 does not seem to reboot the machine. I have to type the reboot command in order for this to actually happen. Any troubleshooting tips here?

how to control Hard Drive light from Linux?
by Rudi Ahlers 24 Jan '11

24 Jan '11

Hi all, Does anyone know how to control a hard drive light from Linux? I'm building a 24bay Linux File server which will run software RAID and I need an easy way for the engineers to see which HDD has gone bad. Most of our NAS devices has 2 lights on the hard drive cages and they automatically signal a bad one (reg light, light constant on , etc) but I can't figure out how todo this from Linux. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

pen drive, hard disk, cd not being detected
by Ritika Garg 23 Jan '11

23 Jan '11

I am working in Centos5.5. Pen drive, hard disk, cd are not being recognised. During booting, "mounting local filesystems [failed]" is displayed among other errors which I am unable to see as the messages proceed fast. Are these messages stored in some file, so that I can check them and report all the errors that are displayed during booting.
