Full Discussion: Rsh passwordless entry
Operating Systems Linux Ubuntu Rsh passwordless entry Post 302888726 by rbatte1 on Monday 17th of February 2014 04:51:50 AM

Please don't be mad Smilie, we're all trying to help.

I thought that /etc/securetty was a list of terminals that would accept a root login. I'm not sure how you have 'added entries' for rsh & rlogin. Please explain and I may learn something too.

I was under the impression that xinetd does indeed control rsh server (alias rexec) and rlogin. Have a look in /etc/xinetd.d and you should find a file for each. There will be a statement within each to disable the service. You will need to set it to no and restart xinetd with service xinetd restart Maybe it's ports 512 & 513 rather than 513 & 514.



Regards,
Robin

XINETD.LOG(5)							File Formats Manual						     XINETD.LOG(5)

NAME
xinetd.log - xinetd service log format DESCRIPTION
A service configuration may specify various degrees of logging when attempts are made to access the service. When logging for a service is enabled, xinetd will generate one-line log entries which have the following format (all entries have a timestamp as a prefix): entry: service-id data The data depends on the entry. Possible entry types include: START generated when a server is started EXIT generated when a server exits FAIL generated when it is not possible to start a server USERID generated if the USERID log option is used. NOID generated if the USERID log option is used, and the IDONLY service flag is used, and the remote end does not identify who is trying to access the service. In the following, the information enclosed in brackets appears if the appropriate log option is used. A START entry has the format: START: service-id [pid=%d] [from=%d.%d.%d.%d] An EXIT entry has the format: EXIT: service-id [type=%d] [pid=%d] [duration=%d(sec)] type can be either status or signal. The number is either the exit status or the signal that caused process termination. A FAIL entry has the format: FAIL: service-id reason [from=%d.%d.%d.%d] Possible reasons are: fork a certain number of consecutive fork attempts failed (this number is a configurable parameter) time the time check failed address the address check failed service_limit the allowed number of server instances for this service would be exceeded process_limit a limit on the number of forked processes was specified and it would be exceeded A DATA entry has the format: DATA: service-id data The data logged depends on the service. login remote_user=%s local_user=%s tty=%s exec remote_user=%s verify=status command=%s Possible status values: ok the password was correct failed the password was incorrect baduser no such user shell remote_user=%s local_user=%s command=%s finger received string or EMPTY-LINE A USERID entry has the format: USERID: service-id text The text is the response of the identification daemon at the remote end excluding the port numbers (which are included in the response). A NOID entry has the format: NOID: service-id IP-address reason SEE ALSO
