"groupadd" command not working

Hi everyone,

I have a problem when trying to create a new group
by using command "groupadd" follow by group name

I've check /etc/group but the group wasn't added.

and when I use command like :
# groupadd clamav
# useradd -g clamav -s /bin/false -c "Clam AntiVirus" clamav
useradd: unknown group clamav <<< give me this results ..

Anyone experiencing problem like this?

 

I keep searching on the internet but still can't get it to work

1.I've logged in as "root"
2.I've try to use fullpath as a command /usr/sbin/groupadd groupname

Please help!

 

What's your distribution?

Is your new group listed in /etc/groups?

 

1.CentOS 5.5

2.Nope, new group doesn't listed in /etc/group
also group.lock files has created

 

Now, It's fixed. I found out a solution. Will post soon!

 

That would be great!

 

You must check your secure log files
/var/log/secure

See what it tell you after type commands.

In my case, /etc/login.defs has been removed from the system.
That's why my "groupadd" commands doesn't work.

So, I decided to copy new login.defs from another machine. And it now worked.
