>Environment:
System: SunOS Implementor 5.5.1 Generic_103640-12 sun4m sparc SUNW,SPARCstation-5
Architecture: sun4
>Description:
appl/gssftp/ftpd/ftpd.c has this:
#ifdef HAVE_GETUSERSHELL
while ((cp = getusershell()) != NULL)
if (strcmp(cp, shell) == 0)
break;
/* endusershell(); */ /* this breaks on solaris 2.4 */
#else
Since the call to endusershell never happens, getusershell() never
rewinds, so if you try to log in a second time, it won't find your
shell.
>How-To-Repeat:
220 Implementor FTP server (Version 5.60) ready.
Name (impl:danw):
331 Password required for danw.
Password: [mistype password here]
530 Login incorrect.
Login failed.
ftp> user danw
530 User danw access denied.
Login failed.
>Fix:
uncommenting the `endusershell' makes it work under solaris 2.5.1,
but I don't know what the problem with 2.4 was...
