Hi Pals
Consider a case where the network interface is there and it is connected to a network.
Only thing left here is I need to set a static ip/ip though dhcp (though ifconfig)
I heard that it is possible to listen even if the ip address is not set. So is there any possibility of an attack over... (1 Reply)
Hi,
I have an executable running on HP-UX, from this executable I need to findout if the portnumber. lets say 7890,7891, 7892 are listening on the remote server running on HP-UX.

bindresvport
BINDRESVPORT(3) BSD Library Functions Manual BINDRESVPORT(3)NAME
bindresvport, bindresvport_sa -- bind a socket to a privileged IP port
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/types.h>
#include <rpc/rpc.h>
int
bindresvport(int sd, struct sockaddr_in *sin);
int
bindresvport_sa(int sd, struct sockaddr *sa);
DESCRIPTION
The bindresvport() and bindresvport_sa() functions are used to bind a socket descriptor to a privileged IP port, that is, a port number in
the range 0-1023.
If sin is a pointer to a struct sockaddr_in then the appropriate fields in the structure should be defined. Note that sin->sin_family must
be initialized to the address family of the socket, passed by sd. If sin->sin_port is '0' then an anonymous port (in the range 600-1023)
will be chosen, and if bind(2) is successful, the sin->sin_port will be updated to contain the allocated port.
If sin is the NULL pointer, an anonymous port will be allocated (as above). However, there is no way for bindresvport() to return the allo-
cated port in this case.
Only root can bind to a privileged port; this call will fail for any other users.
Function prototype of bindresvport() is biased to AF_INET socket. The bindresvport_sa() function acts exactly the same, with more neutral
function prototype. Note that both functions behave exactly the same, and both support AF_INET6 sockets as well as AF_INET sockets.
RETURN VALUES
The bindresvport() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to
indicate the error.
ERRORS
[EPFNOSUPPORT] If second argument was supplied, and address family did not match between arguments.
The bindresvport() function may also fail and set errno for any of the errors specified for the calls bind(2), getsockopt(2), or
setsockopt(2).
