i need to turn on rlogin, it went away and the linux server will not accept any connection. I recently upgraded to rh7.1 and that is when my rlogin went south.  I managed to get telnet up and running, but most of the people on the network like to use rlogin, how do i turn it back on?

hi,
    you can turn it on using either linuxconf or ntsyv.
   
    Using ntsysv or the services menu of linuxconf, simply choose the rlogin and xinetd. You can either restart the machine or manually run the following command:

/etc/rc.d/init.d/xinetd restart

it would be helpful if you post the error msgs which appear in /var/log/messages as soon as you try to login via rlogin. (also which linux distribution have you installed on the second machine)

both have RH7.1
error message:
in.rlogind[7160]: PAM authentication failed for in.rlogind


now on my other box, I installed xinet, but I still don't see rlogin at the ntsysv menu.

#%PAM-1.0
auth       required     /lib/security/pam_securetty.so
auth       required     /lib/security/pam_stack.so service=system-auth
auth       required     /lib/security/pam_nologin.so
account    required     /lib/security/pam_stack.so service=system-auth
password   required     /lib/security/pam_stack.so service=system-auth
session    required     /lib/security/pam_stack.so service=system-auth
session    optional     /lib/security/pam_console.so


now when i get a login prompt and put a valid user name, i do not get a password prompt and login fails, BUT.
if i start with an invalid user, it prompt for a password, then when it fails i can put a valid user  and password and then i can access the system

BECAUSE:
1. backup your  /etc/pam.d/rlogin
2. change you /etc/pam.d/rlgoin to this
auth       required     /lib/security/pam_nologin.so
auth       required     /lib/security/pam_securetty.so
auth       required     /lib/security/pam_env.so
auth       sufficient     /lib/security/pam_rhosts_auth.so
auth       required     /lib/security/pam_stack.so service=system-auth
account    required     /lib/security/pam_stack.so service=system-auth
password   required     /lib/security/pam_stack.so service=system-auth
session    required     /lib/security/pam_stack.so service=system-auth

and you should be up and running in less than a minute :-)
I'm assuming you are using shadow.
