Enabling root user in rlogin

senthil_kumar_1 — Wed, 25 Mar 2009 07:29:43 GMT

Hi

My HP-UX server is configured with rlogin.
I am not able to login by root user directly.

So now i am logging in using normal user and use " su - " to get root login.

Check /etc/hosts.equiv and .rhosts files.

Hi,

Restrict root login to the console
/etc/securetty is used by the login command; the file contains the device names of tty lines (one per line,
without leading /dev/) on which root is allowed to login. We only allow the console.
# echo console > /etc/securetty
# chmod 400 /etc/securetty

remove "console" word from /etc/securetty

Hi,

Are you trying to use rlogin for password-less login?

Or is the problem that you are unable to login directly as root by any means? (rlogin, telnet, ssh)

Perhaps root login is restricted to the console only and not allowed from network ttys? Check for the /etc/securetty file.

HTH, Paul

you need to check /etc/securetty as well as the root user's .rhosts file.

I would recommend configuring SSH for password-less login.

You will need to check your /etc/hosts.equiv and $HOME/.rhosts file for the host and username entries.(Should be in 'hostname' 'username' format.)

Hi Senthilkumar,

>>>My HP-UX server is configured with rlogin.

>>>>So now i am logging in using normal user and use " su - " to get root login<<<

Both the situations are different. If you are not able to login as root directly, you should look at the file /etc/securetty. This file restricts where root should be able to login directly. Most people specify only the console, so root direct login denied from network. root can login directly only on console.

Hope this clears you.

Hi,

In Local Node.(From where you want to rlogin)

#more /etc/hosts
in this file check that remote host entry is there or not. If not then
#vi /etc/hosts
make the entry of remote host.
#more .rhosts
In this file check that remote hostname and user id is there or not (it will looks like host1 root), if entry is not there then
#vi .rhosts
and make the entry.

Do the same in Remote server.

Thnx...Farhan

Hi again,

If you don't have file /etc/securetty file, then you should be able to login as root directly.

If the file contains like below,

# more /etc/securetty
console

root user can login directly only on console.

Are you using SSH i.e port 22 with putty or 23 which is telnet.

If its SSH then check in sshd_config, edit the line "#PermitRootLogin yes, uncomment the line and restart sshd.

Hi Senthil,

Few queries.

how are you trying to login to the serve
ssh/telnet ??

What is the error message you get when you try to login via root

If telnet, try to login via cmd to get the error message.

Hi All

My problem solved. Now i am able to login by root user directly thru rlogin.

Solution:

I have deleted the file "/etc/securetty".
