[Bug 1430181] Re: rpcbind/rpc.statd listen on all interfaces

[Jorge Niedbalski]

There is no way to prevent rpcbind from listening on all interfaces for
TCP connections. The setting "-h" only applies to UDP connections.

Without the attached patch, starting rpcbind with -h makes no effect to
listen on a specific address:

$ rpcbind -h 192.168.100.2

tcp        0      0 0.0.0.0:111             0.0.0.0:*               LISTEN      22011/rpcbind   
tcp6       0      0 :::111                  :::*                    LISTEN      22011/rpcbind   
udp        0      0 127.0.0.1:111           0.0.0.0:*                           22011/rpcbind   
udp        0      0 0.0.0.0:986             0.0.0.0:*                           22011/rpcbind   
udp6       0      0 ::1:111                 :::*                                22011/rpcbind   
udp6       0      0 :::986                  :::*                                22011/rpcbind  

With this patch, starting rpcbind with -h makes effect to listen to a
specific address

$ rpcbind -h 192.168.100.2

tcp        0      0 192.168.100.2:111       0.0.0.0:*               LISTEN      24826/rpcbind   
tcp        0      0 127.0.0.1:111           0.0.0.0:*               LISTEN      24826/rpcbind   
tcp6       0      0 ::1:111                 :::*                    LISTEN      24826/rpcbind
