Konfigurasi Network Interface Card Linux

by FX. Eko Budi Kristanto on May 26, 2007
in Linux, Networking

Saya terbiasa menggunakan konfigurasi jaringan dengan mode GUI karena lebih mudah. Langkah-langkahnya adalah:

dari menu System pilih Administration-> Network

Selain melaui GUI, saat saya berada pada runlevel 3 (berhadapan dengan Server Proxy kantor saya), saya edit langsung file konfigurasiya: /etc/sysconfig/network-scripts/ifcfg-eth0 sampai ifcfg-eth2 (3 interface card yang digunakan)

Setelah itu baru merubah konfigurasi DNS Server yang digunakan pada file /etc/resolv.conf

Oh ya, adakalanya saya menggunakan Webmin (jika kebetulan sedang login remote pakai Webmin)

Setting server apa Mas? Kebetulan saya juga sedang belajar Ubuntu 7.10. Karena kesibukan saya dengan rencana launching situs tempat kerja saya akhir-akhir ini, ditambah dengan rencana mau liburan 3 minggu, artikel tentang konfigurasi server di Ubuntu belum sempat saya tulis. Kemungkinan baru pertengahan Januari.

teman.. saya mempunyai masalah pada proxy server di warnet saya, setelah koneksi di tingkatkan, kenapa kinerja proxy saya jadi melambat (proxy melayani 16 user), sehingga user merasa koneksinya yg lambat, sudah saya coba tingkatkan RAM nya menjadi 1,5 G dan HDD menjadi 250 G. Proxy akan kembali normal lagi bila di restrat,. Ada yang menyarakan untuk mengunakan 2 buah proxy sekaligus (dng metode load balancing) tapi saya ga tau gimana caranya.
bila teman ada memiliki pengalaman yang sama , sudi kira berbagi pengalaman dengan saya, bagaimana cara mengatasinya.

1.sekalian tanya apakah Hardware saya gunakan sudah cukup?

2.bila mengunakan 2 buah proxy sekaligus bagaimana caranya, mohon saran dan penjelasannya

best regards
Hasdi
