What to do? |

Ok, here is a very noob question:
I want to start working with linux more and learn more about admining it.
What exactly should I look into?
It's weird because I have been playing with linux since Redhat 5 back in '97, but all I have really done with it is install it, maybe get a few programs to run on it, and I even compiled a new kernel once many years ago.
But what should I focus on if I want to admin a linux server?
Sorry if this seems a little vague, I really don't know what to ask.
Thanks for any advice.

speed up your hard discs |

if you are finding things a little slow maybe dma is not enabled on your hard disc
to find out if it is or not, try this command as root (assuming /dev/hda is your hard disc, if not try fdisk -l to find out what is your current hd)
Quote:[root@localhost ~]# hdparm -d /dev/hda
/dev/hda:
using_dma = 0 (off)
as we can see here, the hard disc (/dev/hda) is not using DMA, so lets do a quick test before enabling dma.
to test the hdd speed try this
Quote:[root@localhost ~]# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 24 MB in 3.26 seconds = 7.36 MB/sec
[root@localhost ~]#
ok, now lets enable the DMA transfer mode.
Code: [root@localhost ~]# hdparm -d 1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
using_dma = 1 (on)
now check the results of the speed test again
Quote:[root@localhost ~]# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 52 MB in 3.11 seconds = 16.72 MB/sec
[root@localhost ~]#
speaks for itself !
cheers

allow root console access? |

I'm running red hat 9 on a x86 (just to set the seen)
Could anyone tell me how to allow root console access, though telnet and ftp?
I know this is very studid and a very bad security issue, however these machines are used for training purpose and will not have access to the interenet, also the machines can be ghosted at any time if someone does kill the machine.

connecting 2 computers |

I try to connect two computers with fedora core 4 using a crossover cable and an ethernet device on each computer.
I configured each device with
pc1:
ifdown eth0
ifconfig eth0 192.168.0.1
pc2:
ifdown eth0
ifconfig eth0 192.168.0.2
routes seem ok (it creates by default a network route) and I am also sure that the ethernet cards and the cross-over cable work, but I am unable to ping from one machine to another. Any suggestions what could be wrong?
Thanks in advance.

Hey,
I have a netgear 54mbps wireless usb 2.0 adaptor which works fine within the windows operating system, but it requires software to be installed which is a great problem as it is as you all know only windows compatible?
Is it possible to get this to work another way other than me buying a new one. All suggestions much appreciated regards L150 [img]<___base_url___>/uploads/emoticons/default_ohmy.png[/img]
