Hey Arlin,
Have you ever seen this? I hit this 100% of the time trying the 1.2
version of dapltest on an ofed-1.3 system. The debug info below was
obtained by builting the src rpm with debug enabled...
(gdb) r -T T -d -s vic11-10g -D chelsio -i 10 client SR 256 server SR

Its hurling in DT_Mdep_printf() here:
134 /* Pull out IP address and print it as a sanity check */
135 DT_Mdep_printf ("Server Name: %s \n", hostname);
136 DT_Mdep_printf ("Server Net Address: %s\n",
137 inet_ntoa(((struct sockaddr_in
*)target->ai_addr)->sin_addr));
The ai_addr looks ok though:
(gdb) p/x *((struct sockaddr_in *)target->ai_addr)
$3 = {sin_family = 0x2, sin_port = 0x0, sin_addr = {s_addr =
0x8846a8c0}, sin_zero = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}}
(gdb)
Ever seen this?
Steve.
