Dear rekan-rekan,
Bagaimana cara mengkonfigurasi linux redhat 6.2 memakai IP dinamic atau
DHCP.
File-file dan service-service apa saja yang penting dan scriptnya di taruh
dimana.
Nb: Linux RedHat di install pada:
- Notebook Tecra8100
- Ethernet card Xircom 10/100
- Hardisk terbagi atas : /dev/hda1 -> Windows ME drive C
/dev/hda2 -> / Linus Native
/dev/hda5 -> Windows ME patisi drive D
Sebelum dan sesudahnya saya ucapkan banyak terima kasih.
Wassalam

Sebagai tambahan saya telah megikuti procedure tapi nggak berhasil yaitu
problem masih sama
IP belum didapatkan melalui DHCP.

1.Shrink Win98 partition (if you care to keep it around for DVD play,
etc.) using PartitionMagic, FIPS, System Commander or similar tool.
2.On free space, create Linux partitions to appropriate sizes (i.e. /,
/usr, swap, /var, /home, etc)
3.Install RedHat Linux 6.2 w/ GNOME (could try KDE or whatever I
suppose). I used the "text" installation at the RedHat Linux boot prompt. If
you take the
default GUI (Python-based) install, I'm not sure what your outcome
might be :-)
4.Press "i" for interactive startup.
(i.e. as the system is booting up, it'll say "Welcome to Red Hat Linux
- Press 'I' to enter interactive startup." At this time, you need to press
the "i" key, and
you need to be pretty quick about it too, else it'll defaut to
non-interactive :-)
5.Skip the last one "local" it follows "linuxconf" (this will prevent
your keyboard from locking up)
6.Add "alias eth0 3c575_cb" (or whatever your PCMCIA ethernet card is) to
/etc/conf.modules
7.Create "/etc/sysconfig/network-scripts/ifcfg-eth0" with the following
contents:
DEVICE="eth0"
BROADCAST=
ONBOOT="yes"
BOOTPROTO="dhcp"
USERCTL=no
(if not using DHCP, settings would be different here)
8.Run (mandatory or keyboard will lock up) ...
chkconfig gpm off
9.Run (optional to boost performance) ...
chkconfig nfslock off
chkconfig netfs off
chkconfig identd off
chkconfig atd off
chkconfig crond off
chkconfig sendmail off
10.Run (mandatory, keyboard still tended to lock up)...
mv /etc/rc.d/rc3.d/S99local /etc/rc.d/rc3.d/K99local
11.Create "/etc/rc.d/rc.zlocal" with the following contents:
Note - read the manpage for "hdparm" before doing this. You might be
more cautious than I, but I saw an improvement of timed buffer reads
(hdparm -t /dev/hda) from 4 MB/sec to 13 MB/sec:
#!/bin/sh
# speed up the UDMA drive like 3 times faster
/sbin/hdparm -c1 -d1 /dev/hda
You may question why this speeds up performance - here's why I
think so ... Okay - I say this from the timed buffer reads. See my output
below. With 32-bit and DMA
enabled and on this ATA66 drive, I see an improvement from 4
MB/sec to 13 MB/sec.
# hdparm -d1 -c1 /dev/hda
# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 64 MB in 5.02 seconds = 12.75
MB/sec
# hdparm -d0 -c0 /dev/hda
# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 64 MB in 15.43 seconds = 4.15
MB/sec
I did this on another disk on another machine I have. Much faster
IMHO. I haven't experienced any problems on either drive yet with these
enabled. I put it in this
HOWTO so people could try it - and see how to take advantage of
these settings - because it's not very obvious. Took me abit to discover it,
and I'm very happy I did.
12.And prepare it for boot, i.e.
chmod +x /etc/rc.d/rc.zlocal
ln -s /etc/rc.d/rc.zlocal /etc/rc.d/rc3.d/S99mylocal
