Question : pp0 IP configuration.

Hi,

In one of my boxes, when I run "ipconfig" command, it shows as below:

ppp0      Link encap:Point-to-Point Protocol
          inet addr:192.168.234.235  P-t-P:192.168.234.236  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:2818131 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2824365 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3
          RX bytes:193449334 (184.4 MiB)  TX bytes:113155378 (107.9 MiB)

I have checked files in /etc/sysconfig/network and also in /etc/ppp

In both locations, there isn't any configuration defined which talks about the IP 192.168.234.235.

Also this server has only ethernet interface connected. Do you have any idea where else this IP could have been configured ?

Thanks...

Answer : pp0 IP configuration.

For the loopback interface they are equal. They have to be, by definition.
But you are asking about the ppp0 interface, are you not? That is quite a different entity from loopback.
Loopback is not generally a worry. It's one of a number of methods by which processes in your box can communicate with one another.
Every packet sent to loopback is also received from loopback, so Tx and Rx are always equal
