{
char * tail;
our_port = (int) strtol (service, &tail, 10);
if (tail == service)
{
return (ERR_CANT_RESOLVE_SERVICE);
}
else
{
our_port = htons (our_port);
}

serventry = getservbyname (service, "tcp");
if (serventry)
our_port = serventry->s_port;
else
return (ERR_CANT_RESOLVE_SERVICE);
}
But I took it out and just replaced it with portno=25; because &tail wasn't declared anywhere (if I remember correctly). Since this will always be used for e-mail, I figured it was safe to assume a hard coded port of 25.
btw, thank you for helping with this. I'd be lost completely.

Oh, also - I've renamed all occurrences of the_socket to sockfd (including the class definition). Should I take out the declaration of sockfd at the beginning of get_connected() ?

getservbyname
GETSERVENT(3) BSD Library Functions Manual GETSERVENT(3)NAME
getservent, getservbyport, getservbyname, setservent, endservent -- get service entry
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <netdb.h>
struct servent *
getservent();
struct servent *
getservbyname(const char *name, const char *proto);
struct servent *
getservbyport(int port, const char *proto);
void
setservent(int stayopen);
void
endservent(void);
DESCRIPTION
The getservent(), getservbyname(), and getservbyport() functions each return a pointer to an object with the following structure containing
the broken-out fields of a line in the network services data base, /etc/services.
struct servent {
char *s_name; /* official name of service */
char **s_aliases; /* alias list */
int s_port; /* port service resides at */
char *s_proto; /* protocol to use */
};
The members of this structure are:
s_name The official name of the service.
s_aliases A NULL terminated list of alternative names for the service.
s_port The port number at which the service resides. Port numbers must be given and are returned in network byte order.
s_proto The name of the protocol to use when contacting the service.
The getservent() function reads the next line of the file, opening the file if necessary.
The setservent() function opens and rewinds the file. If the stayopen flag is non-zero, the net data base will not be closed after each call
to getservbyname() or getservbyport().
The endservent() function closes the file.
The getservbyname() and getservbyport() functions sequentially search from the beginning of the file until a matching protocol name or port
number is found, or until EOF is encountered. If a protocol name is also supplied (non-NULL), searches must also match the protocol.
FILES
/etc/services
DIAGNOSTICS
Null pointer (0) returned on EOF or error.
SEE ALSO getprotoent(3), services(5)HISTORY
The getservent(), getservbyport(), getservbyname(), setservent(), and endservent() functions appeared in 4.2BSD.
BUGS
These functions use static data storage; if the data is needed for future use, it should be copied before any subsequent calls overwrite it.
Expecting port numbers to fit in a 32 bit quantity is probably naive.
