The Industrial Raspberry Pi Forum

hello, kunbus team,

First, I get a dynamic IP from the DHCP router to eth0 port as 198.168. 10.34. and open the Putty using this IP.

Now by using sudo nano /etc/dhcpcd.conf I set the static IP for eth1 as 198.168.1.254.
Even the IP scanner now shows both IP in the scan list and I open the second Putty window using 198.168.1.254 as shown below.

But I am unable to ping the RevPi (cmd : ping 198.168.1.254) from my system which has given IP 198.168.1.59. even vice-versa is not getting Reply. Please help

Hi Anil, it seems like you have a routing problem. The default route points to the host "192.168.10.1". Also the DNS points to this host. Maybe just a copy+paste thing that happens. Btw. you should use static "ip_address=198.168.1.254/24". If you omit the "/24" the network is just assumed to be a class C network.

Hello Dirk, Thanks for the response
But the default gateway and DNS are always the same as per my knowledge.
I am following this link https://raspberrypi.stackexchange.com/q ... 4428#74428.
Where am I going wrong?
Or maybe my little knowledge of Networks.
Please help me

Hello Dirk,

I solve the problem and here I have explained in detail. Yes, I was making a mistake to add the DNS.

First I will explain my system IP settings as shown below, in which the IP for wireless LAN has opted from wifi router generating IP range 192.168.10.2 to 192.168.10.102 Through DHCP. The IP for the Ethernet adapter side I opted from system administrator as static IP 192.168.1.59. with the DNS as 8.8.8.8and alternative DNS 4.2.2.2

Ethernet adapter Ethernet:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::7d8dec81:51c5%18
IPv4 Address. . . . . . . . . . . : 192.168.1.59
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.254

Wireless LAN adapter Wi-Fi:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::ecad:bd0e:738d:e3ac%3
IPv4 Address. . . . . . . . . . . : 192.168.10.98
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.10.

Now come to Revolution Pi which has two ethernet port eth0 and eth1. First port eth0 of RevPi I get the IP from DHCP router as 198.168.10.71. By using this IP I am able to access the RevPi over SSH-Putty. Now for the second port eth1 of RevPi, I set static IP as 198.168.1.222(Free IP is taken from system admin) using this https://raspberrypi.stackexchange.com/q ... 4428#74428

interface eth1
static ip_address=192.168.1.222/24
static routers=192.168.1.1
static domain_name_servers= 4.2.2.2

Now I am able to communicate (ping) from both ways i.e. from
(1) From my system(PC) to both port of RevPi(Revolution Pi)as

Hi Anil,
tank you for your positive reply.
