ROOT-access and SSH-login
picas...@gmx.net
I have two questions. I were very happy, if somebody could help me!
RedHat Linux 6.0
Current situation:
*Normally root has no login-access (except console)
How to setup these things?:
*root access only for one machine (cs2, eth2, 192.168.2.1) in the
local network and no other!
*e-mail client (on cs2, and only on cs2) should have access to root's
mail over POP3 (other accounts access are ok, ipop3d is running).
Current situation:
*SSH (Secure Shell) connection is not possible...
How can I enable:
*SSH for all users
I tried various things... but could not solve these two problems.
Thank you in advance!
Sincerely
Erkan

disabled for user ids under 10. Since the root user id is 0, remote
access for the root user is not allowed. I don't believe there is anyway
to change this. You can, if you know the root password, do the
following:
1)Login in using a normal userid
2)type the command : 'su root'
3)you will be prompted for the root password. Enter the password and you
are given root permissions. This means you can install, uninstall, start
/sbin programs, do everything the root can do, except check the root
email. You have to be sitting at the console logged in as root to read
and check root email.
I hope this helps!!

I can remember the old S.u.S.e 5.2 times... There was directly
remote login for root possible! (I think it was the entry pty* in
/etc/securetty - but I'm not sure...)
What the problem is:
*root access should permitted only for a specific host
*mail clients cannot login as a user and perform su, cause of
pop3
I think there must be a way...
Thanx for your readiness to help!

ssh is it - compare /etc/sshd_conf (for ssh version 1.x) resp.
/etc/ssh2/sshd_conf (for ssh version 2.x):
(...)
PermitRootLogin yes
(...)
AllowHosts localhost, foobar.com, friendly.org
DenyHosts evil.org, aol.com
(...)
Have a look at
Most recent version is ssh-2.0.13. Main advantage of ssh is:
Passwords are transferred in an encrypted way! This is important due to
sniffers and similar things.
You login in your remote computer (comp.org) by
ssh comp.org
or if you want to use a login name differen from your actual login name:
ssh -l your_remote_name comp.org
The remote computer has to run sshd; ssh version 2 can talk to sshd version 1
(downwards compatible).
Bye, Juergen.

you do get root access but you can not do everything as if you were sitting
at the console. I beleive that the proper command would be : su-
It is not necessary to add the username 'root' as that is exactly (and only)
what the command is used for on a Linux system. The same thing happens (you
are asked for the root password), but you do inherit all the 'goodies' of the
root account. KAS

Hello, if you want to check root's E-mail from another computer, you can
redirect root's e-mail to a user acount in /etc/aliases.
