Hello,
I am using gdb/insight to debug an embedded system across a network
connection and currently don't have the IP address for the node in any name
server or in my local hosts file. When this is the case I found that you
are not able to connect to a remote target through TCP/IP using the IP
address. An example of using an IP address might be the command "target
remote 192.168.1.1:1058". GDB returns an error when trying to do this. I
made a change in the ser-tcp.c file which allows the connection to be made
either by the DNS name or by the IP address. To facilitate the explanation
of the change, I will include the original lines from ser-tcp.c first and
then the new/changes lines to facilitate using an IP address>
Lines 69-74 of original source for ser-tcp.c
if (!hostent)
{
fprintf_unfiltered (gdb_stderr, "%s: unknown host\n", hostname);
errno = ENOENT;
return -1;
}
Lines 69-88 of a modified ser-tcp.c file
if (!hostent)
{
//Can't get information by name try to get by IP address
unsigned long IPAddress = inet_addr ( hostname );
if (INADDR_NONE == IPAddress)
{
fprintf_unfiltered (gdb_stderr, "%s: bad
hostname\n", hostname);
errno = ENOENT;
return -1;
}
hostent = gethostbyaddr((char*)&IPAddress,
sizeof(IPAddress), 2);
if (!hostent)
{
fprintf_unfiltered (gdb_stderr, "%s: unknown
host\n", hostname);
errno = ENOENT;
return -1;
}
}
I hope this change is acceptable and will be incorporated into future
releases of gdb/insight.
Thank you,
Kevin Staggs
