Daftar nama service dan port Linux

Tampaknya blog ini sudah mulai jadi rujukan mahasiswa yang mata kuliahnya sistem operasi Linux. 😀 Ada satu pertanyaan masuk soal port – port di Linux, ada yang jenisnya reserved/trusted (1024 port pertama) dan well known service (WKS). Tugasnya, dimana kita mendapatkan nama layanannya dan port berapa yang dipakai dari dalam Linux itu sendiri.

Secara praktek dunia nyata sangat jarang kita perlu tahu apa named servicenya, tinggal terima jadi saja, tapi kita bisa dengan mudah mendapatkan informasi ini dengan membaca file /etc/services:

less /etc/services

Dan isinya sangatlah panjang:

# /etc/services:

# Network services, Internet style
# IANA services version: last updated 2013-04-10
#
# Note that it is presently the policy of IANA to assign a single well-known
# port number for both TCP and UDP; hence, most entries here have two entries
# even if the protocol doesn't support UDP operations.
# Updated from RFC 1700, ``Assigned Numbers'' (October 1994).  Not all ports
# are included, only the more common ones.
#
# The latest IANA port assignments can be gotten from
#       http://www.iana.org/assignments/port-numbers
# The Well Known Ports are those from 0 through 1023.
# The Registered Ports are those from 1024 through 49151
# The Dynamic and/or Private Ports are those from 49152 through 65535
#
# Each line describes one service, and is of the form:
#
# service-name  port/protocol  [aliases ...]   [# comment]

Saya potong hasilnya sampai port 995 karena kalau semuanya bisa sampai port 40000 sekian dan ada puluhan ribu baris karena ada revisinya juga. Kalau anda ingin tahu lengkapnya bisa cek sendiri atau buka link dari IANA dibawah.

Fungsinya file /etc/services ini adalah sebagai database lokal untuk nama layanan dan port yang diasosiasikannya dan tahu pakai TCP atau UDP transfer datanya.

Teorinya semua aplikasi/program yang bisa menggunakan port maka bisa pakai nama layanannya juga.

  1. Apakabar mas chandra semoga dlm keadaan baik… mas ku kan pke virtualbox Kenapa pada saat reboot / shutdown terus dinyalakan lagi jika ingin pake putty hrus selalu mengaktifkan service ssh start, jd ga secara otomatis sudah tersimpan oleh system
