Rlogin problems

Mike_305 — Tue, 12 Mar 2002 18:04:14 GMT

Hi,

I have two SUN systems and I am trying to rlogin from one system to another system. I already checked the .rhosts file on second system and looks fine, has the correct entry. Every time I try to login it is asking for passwd. What I am missing.

Thanks in Advance.

Mike

Hi ,

1. If you want to log on to Server A from B then put entry for Server B in /.rhosts file of A.

So, /.rhosts file for Server A will be like this

ServerB root

2. Check for following entry in /etc/indetd.conf file

login stream tcp nowait root /usr/lbin/rlogind rlogind

if it is commented, then make it uncommented.

Hope this will works for you.

Thanks,
-Piyush.

In the .rhosts file you can either put the fully qualified hostname or alias (short name). You need to first find out from nslookup what is the primary hostname it returns and use that exact hostname in your .rhosts file.

Hi,

could you also check the entry in the /etc/hosts.equiv file on each systems. There should be the same.

Hope this help,

Hi,

host_a
host_b

If you want to login from host_a to host_b and not be prompted for a password, then the .rhosts file on host_b on the first line should read:

host_a.fully.qualified.hostname username

.rhosts file on host_b should have the fully qualified name of host_a space username (that you are logging in as)

Do you have these set up but still prompting for password ?

Hi, If .rhosts is having a problem then you can create hosts.equiv file in /etc on remote host and add hostname username in hosts.equiv and also check nslookup.

Hope this will help

Hi,

Looked at the inetd.conf file and login entry is not commented. Any ideas.

Try replacing hostnames with corresponding IP-Address .rhosts file.

You should also check the ownership of the .rhosts file. The file must be owned by the user trying to log in, and must be in that users $HOME directory.

Hi All,

Thanks for quick reply. I also want every one to know this is Sun systems.

I have looked in /.rhosts and I am using fully qualified name with user name.

We are using DNS and I nslookup is fine and still I can login without passwd.

Hi Mike,

I tried it on my SUN SYSTEMS works for me...

Did you try putting in the IP address instead of the hostname as Uday mentioned...?

Hi Mike,

Is .rhosts owned by the correct user? Perms set to 600?

Are you using rlogin -l loginid? The HPUX man page says that .rhosts are not used with the -l option unless the user is a superuser.

An easy way to verify what hostname / IP address to put in the .rhosts file:
rlogin (using the password)
tty
who -u (looking for your tty)
the last field in the who output for your tty is what needs to be in .rhosts

Try logging in like this:

rlogin -l

Hi,

I have tried with IP address and still doesn't work. That's why I like HP and HP forms. I posted the question on Sun site and no luck. I have setup rlogin on many system and never ran into this kind of problems.

Thanks,

Mike

Is there a matching entry for the host and user from which you are logging in? hosts.equiv is checked first. Hopefully there is not a "negative" entry for your host and userid.

Is the remote account root? hosts.equiv doesn't apply for root. Only .rhosts.

Hi Mike,

Let me tell you what I did on my sun systems:

hostA
hostB
USER1 on both systems

Logging in from hostA to hostB as USER1

hostB>cat ~USER1/.rhosts
hostA.qualified.host.name USER1

hostA>rlogin hostB.qualified.host.name -l USER1
Last login: Tue Mar 12 10:17:01 from hostA.qualified.host.name
Sun Microsystems Inc. SunOS 5.8 Generic February 2000
You have mail.
hostB>/export/home/USER1#333>

Upon further reading of the Sun man page for rlogin, I don't see anything stating that root doesn't utilize hosts.equiv.

I can't test that (HPUX only here) and I don't remember whether that's true from my Solaris days.

Hi Mike,

Not sure about the Sun, but in HP there is a file /var/adm/inetd.sec for rlogin security. Check this file for any allow/deny.

Hi Mike,
Make sure that the .rhosts file you are edition on the remote server is in user's home directory. if it is root then /.rhosts
if other user then $USER HOME/.rhosts

One thing can be happen if the local user is not existing on remote machine.
