Please help.
In our project I need to establish TCP connection between two sockets on the same host. Normally it should be done over the "lo" local loop. But due to the run-time search for the IP of the destination, - I have to use "eth0" and use "dot IP" notation for the host.
DOesn't work.
Any services between same host sockets don't work.
Even ping.
System (kernel) doesn't allow through.

I appreciate any suggestions.

Vlad.

Also, check your /etc/hosts that your loopback reference is the same as you are trying to use:
