| Yes. If I use 'ping' from the command line I get success.

ping checks the Layer 3 connectivity.  It shows you that you have
a host<->host connection.  It doesn't check Layer 4, TCP.  You can
have host-host connectivity but still not have any programs (server)
listening on the TCP port.

I don't know, I run /bin/ping when I need to, I don't try rewriting it
:-).

| Does it work for you?

No.  /bin/ping does, though.

| Is port 5813 the right port?

ping uses ICMP, not TCP.  ICMP doesn't have ports.
