aneh slackware gue.

IP dah benar, gateway dah benar. tapi koneksi ke intenet tetap gak mau

berikut ini data jaringannya

so why????/

bantuannya donk

[GiKu]

coba kasih traceroute plus diagram koneksinya

apa si linuxboc jadi gateway atau ada gateway laen

gateway cuma atu

[GiKu]

yooo.. boleh dibuat digramnya di mari

INTERNET ---- GW --- CLIENT

silakan di kasih IP di masing2

[your_love]

yooo.. boleh dibuat digramnya di mari

INTERNET ---- GW --- CLIENT

silakan di kasih IP di masing2



Internet ---> Modem --------------> SWITCH HUB ------------> CLIENT
______________IP : 110.139.61.143___________________________IP 192.168.10.XXX
______________GW : 192.168.10.10 ___________________________Gateway : 192.168.10.10
______________Primary DNS 125.160.4.82
______________Secondary DNS 125.160.2.34


Windows Menggunakan DHCP

Dimana posisi linux gue adalah salah satu dari client tersebut dengan IP
192.168.10.110 dan gateway 192.168.10.10

[your_love]

tetap aja berantakan modelnya yax

[GiKu]

begini

INTERNET ----- MODEM ---- CLIENT


MODEM punya 2 interface
1 di sisi external mengarah ke internet
1 lagi di sisi internal

masing2 interface punya IP, tolong koreksi yg ini
IP external 110.139.61.143
IP internal 192.168.10.10

gateway si MODEM adalah IP ROUTER punya ISP, ini belum disebutkan di diagram di atas


nah, giliran si client default gatewaynya mengarah ke IP internal si MODEM

[your_love]

sorry, ketinggalan

Gateway modem yang mengarah ke internet
IP Address 110.139.61.143
Default Gateway 110.139.60.1

[GiKu]

berarti si MODEM gatewaynya 110.139.60.1 bukan 192.168.10.10

cek juga fitur si MODEM kalau ada konfigurasi bertema NAT (Network Address Translation), pastikan NAT-nya aktif

apaan nih ?
kalo kehabisan pulsa, kirim sms ke sembarang aja yg isinya kehabisan pulsa dan minta dimasukin kantor polisi

sebenarnya ini jaringan sudah berjalan dengan baik. permasalahannya adalah, ketika aku mau nambah client, dan client tersebut kebetulan slackware. selama ini client semuanya windows dan berjalan dengan normal.

Jadi aku beramsumsi, tidak ada masalah dengan modem. yang salah ada konfirugasi di slackwarenya.

[GiKu]

boleh di cek lagi di interface internal si MODEM di bagian subnet mask-nya
apakah sama dg yg lain (client2 di internal)

cek juga apakah IP si slakware sudah diizinkan oleh si MODEM untuk lewat

IP Slackware, 192.168.10.110

berdasarkan range DHCP harusnya sudah masuk

[GiKu]

bener sudah masuk

coba di slackwarenya di cek setingan firewallnya

/sbin/iptables -L -n
/sbin/iptables -t nat -L -n

[your_love]

root@serverinet:~# iptables -L -n
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)

Chain POSTROUTING (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)
target prot opt source destination
root@serverinet:~#

[your_love]

kosong semua ya. xixixxixi. parah. kasih perintah iptables nya donk

[GiKu]

kalo kosong malah gak masalah

mantra selanjutnya

route -n
cat /etc/resolv.conf


btw, dari hasil traceroute di atas, sepertinya ada sesuatu dg network interface-nya

ada berapa network card yg aktif ?

[kandalf]

Lho.. sebentar. Client, kan?
Kok maenan iptable?

Coba cek perintah route baik di windows maupun di linux.

[GiKu]

itu standard gw sendiri, walaupun client gw tetap aktifkan iptables - apalagi tetangganya windows

[your_love]

root@serverinet:~# cat /etc/resolv.conf
search localdomain
search localhost
nameserver 192.168.10.110

network card ada 2. satu tidak dipasang LAN. satu

sepertinya mulei ada gambaran

mantra yg 1 lagi belum diamalkan --> route -n

tambahan lagi, coba di ifconfig semua eth-nya

okay, sekarang tambahin default gatewaynya

ini mantranya

route add default gw 192.168.10.10

setelah itu, coba lagi mantra : route -n

coba traceroute juga

matursuwun.

tak lanjut dolo gan. ini sudah luar biasa metode penelurusannya.

yo wis, kalo keluar tolong panggilkan pasien berikutnya

btw, berhubung konsultasinya lewat inet... nanti si PC dg slackware-nya youli sendiri yang semburr ya

[ancuur]

permisi pak dokter...
saya bisulan bisa di sembuhkan gak?

[GiKu]

permisi pak dokter...
saya bisulan bisa di sembuhkan gak?

coba amalkan mantra berikut

route -n
ifconfig
cat /etc/resolv.conf

[ancuur]

dok...

itu ascii bukan? trs copy paste dari mana?

[GiKu]

pake putty aja Kop

tulisannya di blok, trus klik kiri si tetikus

itu sudah meng-copy tulisan di screen dan siap ditemplok di tempat lain

[ancuur]

http://infogue.com/upload/picture_1/20110624-101410_5692.jpg
