Basic Network Administration for SAP Basis

SAP Basis Administrator 1. operating system 2. database admin 3. SAP application server 4. network administration , network admin . basic instalasi, support, proyek teknikal SAP.

Unix, Linux di Windows:

• ipconfig, ifconfig
• unix: ifconfig
• windows: ipconfig /all, ipconfig /release, ipconfig /renew
• network-interface
• ping nomorIP, ping -l nomerIP
• unix: ping www.yahoo.com
• windows: ping -t www.yahoo.com, ping -l 100 www.yahoo.com
• traceroute nomerIP, tracert nomerIP
• unix: tracert www.yahoo.com
• windows: traceroute www.yahoo.com
• akses server
• netstat -a
• unix: man netstat
• windows: netstat -a
• telnet nomerIP nomorport/tcp
• route print, route add, route delete
• file services, file hosts
• konsep IP, mask, gateway
• nomer IP, hostname. hostname www.yahoo.com yahoo.com (dua hostname 1 alamat IP or 2). Resolve, resolving: hostname diterjemahkan alamat IP from file hosts (Unix di /etc/hosts, Windows di c:\windir\system32\drivers\etc\hosts) or from DNS server.
• konsep client server: nomer IP, nomer port
• dasar routing : maksimal manual routing
• 
  

learning technique

• praktek not only in Windows , juga di Linux
• usahakan gunakan CLI (command line interface: parintah DOS, shell)
• paksakan ngetik, jangan copy paste
• dokumentasi
• Windows parameter /h misalnya “ping /h”
• Linux/Unix : parameter -h contohna “ping -h” (??), kadang parameter –help, kadang “man ping”
• simulasi kerjaan
• kalau di Windows, coba juga ingat2 di Linux/Unix (pasti mirip2) juga sebaliknya

Basic tutorial to add IP address to a Windows computer:

• tambah hardware (Network Card, masih bisa adapter boongan) : dari “Control Panel” Add/Remove Hardware –> Add –> Add New –> No,select from list –> Network Adapter –> Manufacturer = Microsoft , pilih “Microsoft Loopback Adapter”
• konfigurasi nomer IP: ti “Control Panel” –> Network … –> pilih anu device name = “Microsoft Loopback Adapter” –> component dipilih = “Internet Protocol (TCP/IP)” (jangan di untick!) –> click tombol properties

· use the following IP address

· IP address = 192.168.100.1

· mask = 255.255.255.0

· gateway = bisa dikosongkeun

· klik OK

• hasilnya komputer ber alamat 192.168.100.1, test “ping localhost”, “ping 192.168.100.1″, “ipconfig /all”

Scheduled Jobs:

• telnet dan konsep client/server, contoh kasus Web server+ SAP server: contoh “telnet www.yahoo.com 80/tcp” ( response server yahoo.com di port 80 / web server) atau “telnet 1.1.1.1 25/tcp” (akses port smtp/email server)
