Appendix D. Testing the connection to the VSAT
D.1 Ping Function
The VSAT CLI ping command is useful for determining the status of the network and various foreign
hosts, tracking and isolating hardware and software problems, and testing, measuring, and managing
networks. The Ping command bounces a small packet off a domain or IP address to test network
communications, and then tells how long the packet took to make the round trip.
Example:
ping <ipaddr> [<options>]
ipaddr IP address to ping
<options>
-t
continuous ping until stopped, CTRL-C to stop
-t has precedence than -count
-size|-s <size> size in bytes (32 to 1400 bytes) default size 64 bytes
-n|-c|-count <count> Number of echo requests to send.
default five echo requests
Examples:
ping 10.10.11.2
ping 10.10.11.2 -t -size 128
ping 10.10.11.2 -c 10 -s 100
ping 10.10.11.2 –t
ping 192.168.11.26
64 bytes from 192.168.11.26: time=42 ms
64 bytes from 192.168.11.26: time=42 ms
64 bytes from 192.168.11.26: time=94 ms
64 bytes from 192.168.11.26: time=60 ms
64 bytes from 192.168.11.26: time=38 ms
--- 192.168.11.26 ping statistics ---
5 packets transmitted, 5 received, 0 percent packet loss
rtt min/avg/max = 38/58/94 ms
D.2 FTP Server (Upload/Download)
The internal FTP server allows user to conduct FTP server testing for satellite link to hub for
upload/download of predefined test pattern file. The FTP server test can be conducted for both LAN and
DVB interfaces. The internal FTP server test is intended to test the upload and download of files using the
FTP feature between the hub / local PC with the terminal.
FTP to LAN interface
The following example shows how to use the FTP to LAN interface for downloading.
The same procedure can be followed for uploading FTP to LAN interface.
1. Logon the VSAT to the HUB.
2. From a workstation on the HUB side, log on to the VSAT using DOS prompt and the FTP
command. Operator can use either root or install user.
3. Type FTP <LAN IP address of the terminal>.
4. Enter the correct user name and password.
