1 Hi all:
2 I meet a very strange problem on my NIS. I test two cases, which one is
3 a Gentoo i386 box, and the other is Gentoo AMD64 box.
4 I referenced this page:
5 http://www.linux-nis.org/nis-howto/HOWTO/settingup_client.html , and can
6 successfully login.
7
8 But when my directory has unknown UID on AMD64 box, it will return a
9 SEGMENTATION FAULT error.
10
11 Then I use the following code to verify the client settings:
12
13 #include <stdio.h>
14 #include <pwd.h>
15 #include <sys/types.h>
16
17 int
18 main(int argc, char *argv[])
19 {
20 struct passwd *pwd;
21
22 if(argc != 2)
23 {
24 fprintf(stderr,"Usage: getwpnam username\n");
25 exit(1);
26 }
27
28 pwd=getpwnam(argv[1]);
29
30 if(pwd != NULL)
31 {
32 printf("name.....: [%s]\n",pwd->pw_name);
33 printf("password.: [%s]\n",pwd->pw_passwd);
34 printf("user id..: [%d]\n", pwd->pw_uid);
35 printf("group id.: [%d]\n",pwd->pw_gid);
36 printf("gecos....: [%s]\n",pwd->pw_gecos);
37 printf("directory: [%s]\n",pwd->pw_dir);
38 printf("shell....: [%s]\n",pwd->pw_shell);
39 }
40 else
41 fprintf(stderr,"User \"%s\" not found!\n",argv[1]);
42
43 exit(0);
44 }
45
46 Finally, I found that getpwnam() call will cause segmentation fault
47 rather than return NULL on pass a non-exist username on AMD64 box.
48
49 Is anybody has encounter this situation?

51 Regards,
52 Weicheng.
