In our environment i have to ssh to each an every servers

i have to create a user name on 30 severs manually it takes much time so need a script to do this task i have googled and found some for loop scripts but it did not fullfill the requirement.
First i have to check whether the users exists and not and later add the user or reset the password for user using script

I found an old laptop that has centos 5.5 installed. I reset the root password, but I need to reset the gui password. Is there a way to view this password or reset it? I have not worked with Linux over 5 years and am rusty on all the commands

Wow, I got my new Linux pc yesterday and it's very very fast. It's faster than my new MacBook.
So I go to the user account which also says administrator so I'm presuming that's the root owner?????? and I typed in my name and changed the password. The guy who sold it to me named the password user and the computer user. Yet when I go to the terminal my username and computer is still called user@user
How do I change the root password and computer name?

A few of my servers show that this user id has expired.

I know that this is the name of a user account and group account and if I check out /etc/passwd there is an entry under /sbin/nologin. And, if I check under say top -u nobody, I don't see anything running for that user account. However that is the extent of my knowledge on this user account.

Should I be concerned that the passwd for this account is expired or are there cron jobs/programs that rely on this account?

thanks

Since this morning i have a problem with logging in on my user account in Linux Mint 17.1 Mate. After entering the password I get a black screen. Logging in as guest (without password) works fine.
How can I get back to my user account.

Hello,

I just configured proftpd and it's working fine, but i had a doubt "How to create a new user list" and also how to create a new login form by that clients can create their own account without the knowledge of admin, and the information about the user need to store in server. Anyone tried the above scenario? If yes please let me know how!

Hi

I unfortunately can not remember my supa user password for Ubuntu linux on my Odroid U3.

Being new to linux I am lost as to how to restore or reset the password.

Any help offered will be really appreciated.

Hello, I'm sort of a novice Linux user and was running into an issue with user migration. I'm trying to migrate users and groups from a RHEL 5.11 install to a CentOS 6.6 install, both systems are 64 bit. Initially I tried to do an rsync of the passwd, shadow, group and gshadow files with no luck. When trying to login with an existing account on the new server I get access denied. I tried to change the password on the new server, but even then it doesn't seem to change the password and I still get access denied. I then tried to tar up the four above files and then extracted them on the new server, but the same issue existed. I also created a new account on the old server, copied all the necessary files over to the new server and still have the same issues. Any ideas what I may be doing wrong or what I can try next? This is getting frustrating!

Thanks!
