I create a virtual interface on interface eth0.
eg. mechine 1 and mechine 2 have ubuntu as OS mechine 1:
ifconfig eth0:1 172.16.105.1 netmask 255.255.255.0
and then check - # ping 172.16.105.1 it will give icmp reply and then i check a port on this virtual interface.
nc -vz 172.16.105.1 22
Connection to 172.16.105.1 22 port [tcp/ssh] succeeded!
mechine 2:
ifconfig eth0:1 172.16.105.1 netmask 255.255.255.0
and then check - # ping 172.16.105.1 it will give icmp reply and then i check a port on this virtual interface.
nc -vz 172.16.105.1 22
Connection connection refused.
SSHD is running on both mechine at their physical interface.
mechine 2 is working fine. then what is the problem with mechine 1?
Please reply me soon..
