Bila anda pernah install Fedora 7.10 dan mengalami proses start up yang lama sekitar 3 menit pada proses Starting e-mail transport, dimana pada proses itu juga ada proses starting send email dan starting sm-client, maka pengalaman anda sama dengan saya. Solusinya :
1. Edit file hosts pada directory etc :
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.0.94 TestSvrMIS (isikan IP server anda dan di ikuti nama servernya)
2. Eksekusi command di bawah ini
[root@TestSvrMIS etc]# chkconfig --list |grep sendmail
sendmail 0:off 1:off 2:on 3:on 4:on 5:on 6:off
Tampak runlevel 2,3,4,5 pada system service sedang aktif, supaya pada start awal service ini tidak di jalankan, maka runlevel pada system ini perlu di off kan, dengan cara :
[root@TestSvrMIS etc]# chkconfig sendmail off
[root@TestSvrMIS etc]# chkconfig --list |grep sendmail
sendmail 0:off 1:off 2:off 3:off 4:off 5:off 6:off

Sedikit informasi ttg chkconfig :
CHKCONFIG(8) CHKCONFIG(8)

NAME
chkconfig - updates and queries runlevel information for system services

SYNOPSIS
chkconfig --list [name]
chkconfig --add name
chkconfig --del name
chkconfig --override name
chkconfig [--level levels] name
chkconfig [--level levels] name

DESCRIPTION
chkconfig provides a simple command-line tool for maintaining the /etc/rc[0-6].d direc-
tory hierarchy by relieving system administrators of the task of directly manipulating
the numerous symbolic links in those directories.

This implementation of chkconfig was inspired by the chkconfig command present in the
IRIX operating system. Rather than maintaining configuration information outside of the
/etc/rc[0-6].d hierarchy, however, this version directly manages the symlinks in
/etc/rc[0-6].d. This leaves all of the configuration information regarding what services
init starts in a single location.

chkconfig has five distinct functions: adding new services for management, removing ser-
vices from management, listing the current startup information for services, changing
the startup information for services, and checking the startup state of a particular
service.

When chkconfig is run without any options, it displays usage information. If only a
service name is given, it checks to see if the service is configured to be started in
the current runlevel. If it is, chkconfig returns true; otherwise it returns false. The
--level option may be used to have chkconfig query an alternative runlevel rather than
the current one.

If one of on, off, reset, or resetpriorities is specified after the service name, chk-
config changes the startup information for the specified service. The on and off flags
cause the service to be started or stopped, respectively, in the runlevels being
changed. The reset flag resets the on/off state for all runlevels for the service to
whatever is specified in the init script in question, while the resetpriorities flag
resets the start/stop priorities for the service to whatever is specifed in the init
script.

By default, the on and off options affect only runlevels 2, 3, 4, and 5, while reset and
resetpriorities affects all of the runlevels. The --level option may be used to specify
which runlevels are affected.

Note that for every service, each runlevel has either a start script or a stop script.
When switching runlevels, init will not re-start an already-started service, and will
not re-stop a service that is not running.

chkconfig also can manage xinetd scripts via the means of xinetd.d configuration files.
Note that only the on, off, and --list commands are supported for xinetd.d services.
OPTIONS
--level levels
Specifies the run levels an operation should pertain to. It is given as a string
of numbers from 0 to 7. For example, --level 35 specifies runlevels 3 and 5.

--add name

This option adds a new service for management by chkconfig. When a new service
is added, chkconfig ensures that the service has either a start or a kill entry
in every runlevel. If any runlevel is missing such an entry, chkconfig creates
the appropriate entry as specified by the default values in the init script. Note
that default entries in LSB-delimited ’INIT INFO’ sections take precedence over
the default runlevels in the initscript.

--del name
The service is removed from chkconfig management, and any symbolic links in
/etc/rc[0-6].d which pertain to it are removed.

Note that future package installs for this service may run chkconfig --add, which
will re-add such links. To disable a service, run chkconfig name off.

--override name
If service name is configured exactly as it would be if the --add option had been
specified with no override file in /etc/chkconfig.d/name, and if /etc/chkcon-
fig.d/name now exists and is specified differently from the base initscript,
change the configuration for service name to follow the overrides instead of the
base configuration.

--list name
This option lists all of the services which chkconfig knows about, and whether
they are stopped or started in each runlevel. If name is specified, information
in only display about service name.


Ok .. sudah selesai...

Download dulu Software reseter nya :
Canon IP 1200
Canon IP 1300
Canon IP 1600
Canon IP 1700

Nah setelah selesai mendownload, ekstrak file-file tadi, lihat attribut filenya, jangan sampai ada yang Read Only. Selanjutnya, masuk tahap service mode/reset manual.
Untuk reset manual langkah-langkahnya sebagai berikut :
1. Matikan Printer
2. Cabut Kabel Listrik dari Printer
3. Hidupkan printer dengan cara : Tekan tombol Power jangan dilepas,

kemudian masukan kabel listrik/power, Sambil jari menekan tombol power, tekan tombol resume sebanyak 2 kali menggunakan jari yang lainnya. Kemudian lepaskan Tombol Power.
4. Printer akan hidup, nah kalau lampu led/indikatornya sudah berwarna hijau (tidak blinking), artinya anda sudah berhasil mengaktifkan service mode/reset manual.
5. Nah selanjutnya klik software reseternya, secara umum gambarnya sebagai
berikut :

IP 1200,1300,1600,1700,1300

Ikuti Langkah-Langkah di atas

Tampak hasil dari DEVICE ID

Tampak Hasil dari EEP-Rom INFORMATION

Lakukan instruksi berdasarkan no urutnya. Penjelasannya sebagai berikut :
Oh ya sebelumnya driver printer dan printernya harus sudah dalam posisi hidup atau aktif.
1. Masuk ke folder reseternya
2. Klik GeneralTool.exe
3. maka muncul gambar seperti tersebut di atas :

Ikuti langkahnya :
1. Pastikan Port USB sudah terpasang dan pilih USB yang aktif.
2. Get Deivice ID -> untuk mendapatkan ID dari printer tsb.
3. Cheklist EEProm Clear
4. Sebelumnya pasang dulu kertas, kemudian Klik Test Pattern 3.
5. Tekan Tombol Platen & setelah itu Main.
6. Tekan Tombol EEP-Rom Information untuk melihat hasil dari reset tadi, pastikan angka dari Dd dan Ds sudah nol semua.
7. Dengan demikian maka printer anda sudah selesai di reset.

Untuk dapat mengupdate repository dari internet, dan untuk mengakalinya supaya lebih cepat, krn di indonesia sudah ada beberapa server repository yang bisa di update, yaitu Repo.ugm.ac.id, Repository ITS, Kambing.ui.edu, www.foss-id.web.id, ftp.itb.ac.id , indika.net.id , komo.vlsm.org dan mirror.cbn.net.id

Setelah anda mendapatkan pilihan yang dirasa tepat maka anda dapat mengarahkan synaptic menuju alamat situs tersebut. Beberapa mirror sudah memberikan list untuk update. Anda dapat menyalin list update tersebut ke dalam file /etc/apt/source.list. Dapat menggunakan editor semacam pico, vim, kate , kwrite,dst untuk mengubah daftar list download paket repository.
