could not login after installing centos 5.2

windstory · 12-17-2008, 10:42 PM

I installed centos 5.2.
And invite my friend through ssh.

However he could not make login.

Also, I can't make a new user with "adduser" or "useradd".
These commands returned "unknown command".

How can I solve this problem?

Are you running adduser as root?

What does your friend's system say? Is sshd running (ps aux | grep sshd). Is port 22 open on your firewall, and is it forwarded to you machine?

More info please.

billymayday,

Thanks for your kind reply.

I didn't checck 'ps aux | grep sshd" and firewall.
That's why I installed firewall and selinux disabled.

For port 22, I don't havve an idea how to check port 22.

I will check 'ps aux | grep sshd" and firewall, and repost here.

For root, I changed user with "su" command.

Try "su -" instead of just "su". That should fix the environment variables (esp path).

billymayday,

"su -" worked.
However, there are another problem.

After inputting password, "access denied" comes out.

Is there another procedure?

Are you using root's password?

No.

User tester1's password for logging in through ssh with putty.

Oh - I thought the password was to do with su -

Can you start a terminal session as your user, and try

su tester1

enter the user's password and see if that works. Then we'll know if it's just ssh or something else.

Yes, "su tester1" was worked, and password also worked on local box.
