why i could not rlogin from hosta to hostb

[王曦_1]

hi erpert:

i have already add a "+" to /etc/hosts.equiv in hostb, and add "hosta" to /home/user01/.rhosts,
but user01 still could not rlogin to hostb from hosta, why ??
and root could rlogin to hostb,

thanks

Hi,

Please note the following things.
1. root user when using rlogin is not using /etc/hosts.equiv file.
2. As you wrote you put an entry for hosta in .rhosts file un users home directory, you just check the permission of this file this file should be owned by user01.

please check this and update status.

Hi,

You could be suffering from a DNS resolution problem. Instead of using the hostname in the .rhosts file use the IP address.
Does the local /etc/hosts file contain the IP address and name of the other server.

I can't stand rhosts, but I agree this is probably DNS related.

Try converting the hostnames to IP addresses.

This should be easy to test.

Try some ping commands.

from hosta

ping hostb

from hostb

ping hosta

If there is a DNS problem, the pings should fail.

If its intermittent, your ping times should vary wildly.

i also check the ownership of the .rhost, and i use the ip address instead of hostname, but the problem still there,
my god , what can i do

Is either of the systems set up as trusted ?

Can you verify these?

-r-sr-xr-x 1 root bin 53248 Nov 14 2000 /usr/bin/login
-r-sr-xr-x 1 root bin 36864 Nov 14 2000 /usr/bin/rlogin


$HOME/.rhost = ??
/etc/passwd = ??
/etc/hosts = ??
/etc/hosts.equiv = ??

Are using Klogin instead of rlogin? grep in inetd.conf.

Do you get a login prompt? Any error messages? Do you see "...checking disk quotas..."?

Is everyone using standard shells like sh, ksh or csh?

do you have an /etc/cmcluster/cmnodelist file?

Please do not just say that you 'checked' things, but give the details, i.e. ll(1), cat(1), hostname(1), nslookup(1), etc., etc. output.

Note that a .rhosts file *MUST* be owned by the user in whose home directory it is, i.e. /home/user01/.rhosts *MUST* be owned by user user01. If it is owned by somebody else, rlogin (without a password) will *NOT* work.

you must have the same user account on both servers to use "rlogin hostb", otherwise, you must use rlogin -l user_on_hostb.

rlogin for root doesn't check /etc/hosts.equiv , only /.rhots takes effect.

thanks,

Plus, make sure /home/user01/.rhosts has global read access, like r--r--r--, it's very important.

1.first ping a from b and b to a.

2. ensure usernames are identical on each host.
User1 and user1 are not identical. (some people are not UNIXfiles.)

3. vi .rhosts and put in
full domain.hostnamea in b
and full domain.hostnameb in a
for two way transparency.

4. chown user .rhosts

5. chmod 444 .rhosts.

6. su - user

7. rsh a /bin/ls /tmp or other populated directory to check

8. rlogin alfred_e_newman

Hope this helps...
