rlogin is working but remsh is not working

senthil_kumar_2 — Thu, 21 May 2009 14:05:18 GMT

Hi

i am able to rloin system1 from system10 with out prompting for password. but i am not able to run remsh in separate or in script.

I am getting following error when trying to run remsh from system10

Ex:

root@system10:/root > remsh system1 -n grep ze4egi /etc/passwd
remshd: Login incorrect.

But i am able to rlogin in to system10 successfully.

inetd.conf file of system 1

login stream tcp nowait root /usr/lbin/rlogind rlogind
shell stream tcp nowait root /usr/lbin/remshd remshd
exec stream tcp nowait root /usr/lbin/rexecd rexecd

How to solve this problem

Same suggestion as your other rlogin question: Have you verified that root's home directory is set to the same location in both /etc/passwd files?

Since you seem to be doing a lot of remote operations, I need to reinforce my suggestion of using ssh instead of the insecure r- daemons, as in rexecd, remshd.

You will realize, life is much simpler once you set up your working key pairs.

Hi,

Did you checked inetd.sec file ?

inetd.sec is a file that can be used to restict access of inetd services (ftp, telnet, rlogin etc) to particular networks. The file is found at /var/adm/inetd.sec. If this file does not exist then inetd services are open to all ip addresses.

Hi Senthil,

If system1 to system10 does not work then the issue is on system10.
Many things need to happen on system10.

1) remsh needs to be configured in inetd.conf
2) if inetd.sec is being used then remsh needs to be allowed from system1 and others.
3) .rhost file on system10 must be configured properly. If using hostnames then /etc/hosts must be configured correctly for system1.
4) If there is a firewall between system1 and system10 then the firewall needs to be configured correctly.
5) What are the permissions on the .rhosts file on the system10 that is not working? The permissions should be 600 (-rw-------)

Hi Kumar !!

First you should put related problems in the same threath !!

second Please check also your /etc/hosts

if you want thas system1 connect to system2 your /etc/hosts of the system2 should look like this:

xx.xx.xx.xx system2.domain.com system2 xx.xx.xx.xx system1.domain.com system1
127.0.0.1 localhost loopback

Best regards !!
