Checking the Connection
Once you have set up a PPP connection, there are some steps you can take to test the connection. First, type:
moxa@Moxa:~# ifconfig
After executing the command, you should be able to see all of the available network interfaces.
ppp0 should be one of the network interfaces. You should recognize the first IP address as the IP address of
the computer, and the P-t-P address is the address of the server. The output should be similar to this:
lo Link encap Local Loopback
inet addr 127.0.0.1 Bcast 127.255.255.255 Mask 255.0.0.0
UP LOOPBACK RUNNING MTU 2000 Metric 1
RX packets 0 errors 0 dropped 0 overrun 0
ppp0 Link encap Point-to-Point Protocol
inet addr 192.76.32.3 P-t-P 129.67.1.165 Mask 255.255.255.0
UP POINTOPOINT RUNNING MTU 1500 Metric 1
RX packets 33 errors 0 dropped 0 overrun 0
TX packets 42 errors 0 dropped 0 overrun 0
Now, type:
moxa@Moxa:~# ping XXX.XX.XXX.XXX
where XXX.XX.XXX.XXX is the address of your name server. The output should be similar to the following:
moxa@MOXA:~#
sudo ping 129.67.1.165
PING 129.67.1.165 (129.67.1.165): 56 data bytes
64 bytes from 129.67.1.165: icmp_seq=0 ttl=225 time=268 ms
64 bytes from 129.67.1.165: icmp_seq=1 ttl=225 time=247 ms
64 bytes from 129.67.1.165: icmp_seq=2 ttl=225 time=266 ms
^C
--- 129.67.1.165 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 247/260/268 ms
moxa@MOXA:~#
Try typing:
moxa@Moxa:~# netstat -nr
You should see three routes similar to the following:
Kernel routing table
Destination Gateway Genmask Flags Metric Ref Use
iface
129.67.1.165 0.0.0.0 255.255.255.255 UH 0 0 6
ppp0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 129.67.1.165 0.0.0.0 UG 0 0 6298
Ppp0
If your output looks similar but does not have the destination 0.0.0.0line (which refers to the default route
used for connections), you may have run pppd without the defaultroute option. At this point, you can try
using Telnet, ftp, or finger, bearing in mind that you will have to use numeric IP addresses unless you have
configured /etc/resolv.conf correctly.
