 |
|
Like many people new to gentoo, I have one everyday user in addition to root. Somewhere along the install and update cycle, I make some etc-update decision that messed up my everyday user account.
When logging in as myuser, I get the following warning:
| Code: | /usr/bin/whoami: cannot find username for uid 1000
-bash: [: =: unary operator expected
I have no name!@myhost# |
What info can I provide to help diagnose the problem? Here's a few pertinent greps:
| Code: | # grep myuser passwd
myuser:x:1000:100::/home/myuser:/bin/bash
# grep myuser group
wheel::10:root,myuser
audio::18:root,myuser
users::100:games,myuser
|
I would also like to have a group with the same myuser name, I got used to having that when I was on redhat. Thanks. |

Can you give us the contents of /etc/nsswitch.conf?
Also, you might issue:
getent passwd | grep myuser
Another file that might be of interest is /etc/pam.d/system-auth |

myhost root # id myuser
uid=1000(myuser) gid=100(users) groups=100(users),10(wheel),18(audio)
(as the broken user)
I have no name!@myhost# id

Is the whoami binary broken? What happens if you issue whoami?
It is supposed to give you the exact same output as id -un
What are the permissions on /etc/passwd? |

I was mistaken about the output I quoted, I think. I userdel'd that user, and recreated it. Now logging in as 'myuser' I get:
| Code: | I have no name!@myhost myuser $ whoami
whoami: cannot find username for UID 1000
I have no name!@myhost myuser $ id -un
id: cannot find name for user ID 1000
1000 |

-rw------- 1 root root 505 Feb 15 20:06 shadow |

My /etc/passwd and /etc/group have read permissions for group and other set. Try:
| Code: | | chmod 644 /etc/{passwd,group} |
