Interesting FTP error in Solaris 10-ROOT cannot access FTP
System environment:
Operating system: Solaris 10
Error phenomenon:
[root@solaris187:/] # ftp 127.0.0.1
Connected to 127.0.0.1.
220 solaris187 FTP server ready.
Name (127.0.0.1:root): root
331 Password required for root.
Password:
530 Login incorrect.
Login failed.
Root users cannot access ftp, other users can!
Case study:
It defaults to security under Solaris. Root users are prohibited from accessing ftp and are restricted through the / etc/ftpusers file.
If the root user is removed from this file, the root user can access the ftp, but this case still cannot!
Case study:
1. If it is a profile restriction, it should be that the root user does not have the opportunity to enter the password and is directly rejected.
2. You can enter a password to indicate that the authentication identity is wrong; it may be a password or / etc/passwd file problem.
Troubleshoot the password and view the / etc/passwd file:
[root@solaris187:/] # cat / etc/passwd

Unexpectedly, it was found that in the entry of the root user, the shell part was missing a "/" before the usr, so that shell could not be enabled!
Change to:
Root:x:0:0:Super-User:/:/usr/bin/bash
@ so far, the problem is solved!
