SuSE-11 Ownership of files having root got changed
Hi Experts,
I have create a new user with uid and gid as 0 in SuSE-11 Server. After that all the files having root owner ship are showing as new user name as owner. If I login as root, and type 'id' command, it also shows the new user.
Sample output from my server.
Code:
host:~ # id
uid=0(test) gid=0(root) groups=0(root),104(sfcb)
host:~ # cd /
host:/ # ll
total 109
drwxr-xr-x   2 test root  4096 Sep 20  2010 bin
drwxr-xr-x   4 test root  1024 Feb 14 12:02 boot

drwxr-xr-x  17 test root  4096 Feb 11 10:00 var
host:/ #

How can I change it back to root ? I need the new user as is, because it is used by a monitoring tool.

is the user test above the root user in /etc/passwd?

maybe you want to post your passwd file


in general it's not recommended to use users with id 0 other than root,
what do you want to achieve with it? tried sudo?

cheers

i tried this out:

this order in passwd:

Code:
root:x:0:0:root:/root:/bin/bash
test:x:0:0:root:/root:/bin/bash

id as root:

Code:
uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel)



this order in passwd:

Code:
test:x:0:0:root:/root:/bin/bash
root:x:0:0:root:/root:/bin/bash

id again:

Code:
uid=0(test) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel)

so simply change the order and you should be fine

It will use the name with the same uid that it finds as last in the /etc/passwd. Usually you use something like sudo to have a program being run with root permissions and do not add another user with uid 0.

I frankly do not understand why this monitoring tool needs such an account. The standard way to handle this is for the tool to be a setuid root binary.

Hi funksen,

I tried by changing the order of users in /etc/passwd file but the system was beheaving unexpected way!! I modifed the order of user as you said, then 'id' was showing root as user properly, then reverted back to the original order but 'id' showing same root and files ownership also root.

Another thing I noticed that it happened only for some server in which i created new user.

sudo is not installed in these servers.

@fpmurphy, the monitoring tool use shell commands to capture the information from the system hence it require root privillage account. Now I come to know that it support configuring password less ssh connection using public key. I will try to configure password less connection for root and will remove the new user account.

Thanks for your inputs...
