- Red Hat Enterprise Linux 5.3
Customer trying to su as root user accounts and it failed with the error below :
[datacenter@localhost log]$ su - root Password:: No such file or directory
same error occurs if try to su as user x.
[datacenter@localhost log]$ su - x Password: : No such file or directory
Not even able to ssh as the user root.
This issue happen because customer edited the /etc/passwd from a Window environment.
Noticed /etc/passwd file had DOS line endings.
For example when we use vi editor to open /etc/passwd file following were noticed :
vi /etc/passwd root:x:0:0:root:/root:/bin/bash^M
The ^M should not be there and is likely introduced by editing on a Windows platform (although there could be other explanations).
In order to fix the issue remove ^M at the end of each line in /etc/passwd file.
Attempting to edit Red Hat configuration lines from Windows add ^M at end of line.
Windows line ending charactors are different to linux line ending charactors.
