Generic Host Process for Win32 Services

Generic Host Process for Win32 Services

Sungguh meropotkan dan menjengkelkan jika masalah seperti gambar di bawah muncul...



Masalah ini ditimbul karena adanya bugs security pada Windows SP2 bahkan SP3 pun tidak luput dari penyakit ini....
Sungguh aneh Service Pack yang seharusnya membereskan masalah malah memberikan masalah...

Efek dari penyakit ini koneksi internet akan terputus bilapun jalan koneksinya kecepatannya kalah dari jalannya seekor keong.

P3K untuk penyakit ini...

1. download patch di http://gnupg.cdpa.nsysu.edu.tw/Patch/WinXP/en/WindowsXP-KB894391-x86-ENU.exe

2. Blok Port 135 dan 445 (Mainkan registernya)

a.Blok Port 445
- Buka Registry Editor. Lalu ke posisi
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\NetBT\Parameters
cari TransportBindName , semula berisi \Device\ . lalu edit dan kosongkan saja.

b. Blok Port 135
HKEY_LOCAL_MACHINE\Software\Microsoft\OLE

cari EnableDCOM edit value "Y" menjadi "N"

3. Reboot PC anda....

Good luck....kalo ngga berhasil marahin aza Bill Gate

Simple Bridge (Latihan RSTP)

Suatu ketika ada panggilan test disuatu ISP di bandung salah satunya test adalah membuat simple bridge seperti gambar di bawah.

Waktu test aku menggunakan linux dan terus terang ada sedikit kendala karena yang dinilai kecepatan dan ketepatan saat mensetting router2.

di linux kendalanya harus install paket seperti ebstables, bridge-utils, vlan, dll walaupun tinggal
apt-get install lom lagi konfigurasinya yang rada panjang dan modul yang harus diload.



untuk itu aku disuruh nyoba sama sys admin ISP untuk mencoba OpenBSD dan ternyata hasilnya keren banget cepat dan mudah g perlu install apapun karena semua paket telah include ke dalam kernel.

jika ada yang mau nambahin pake linux boleh2 aza di tunggu yaa...

Singkronisasi Waktu

Untuk mencocokan jam sistem dengan jam hardware
===============================================

Cara 1
------

Jam sistem sebelum di rubah
vpn:/# date
Sat Jan 3 03:54:26 WIT 2009

untuk mencocokan jam sistem dengan jam hardware
vpn:/# hwclock --hctosys --localtime

Jam sistem setelah di rubah
vpn:/# date
Fri Jan 2 20:57:59 WIT 2009

untuk membuat permanen silahkan masukin ke dalam scripts command "hwclock --hctosys --localtime"

Cara 2
------

vpn:/# vim /etc/default/rcS

Isinya harus seperti dibawah ini :

TMPTIME=0
SULOGIN=no
DELAYLOGIN=no
UTC=no
VERBOSE=no
FSCKFIX=no
RAMRUN=no
RAMLOCK=no

vpn:/# reboot

Silahkan cek jam di bios komputer dan di sistem hasilnya pasti sama...

Lumayan menghemat BW karena tidak membutuhkan koneksi ke NTP Server
