Hi

It seems that my /etc/hosts file is not being read when trying to rlogin to another workstation.

If I try to rlogin using rlogin <hostname> the error '' unknown host" comes up. Note that the host is defined in both the local and remote systems.
But if I do a rlogin using rlogin <ip address> it works.

This is also affecting an XTerminal connection to my worksation.

It seems that my /etc/hosts file is not being read when trying to rlogin to another workstation.

Is /etc/hosts readable on your system? (ls -la /etc/hosts)
is it in there correctly? (show us the entry of the host in /etc/hosts)
On most systems you can tell if it first has to use dns or hosts or both how did you set this?
is there a dns in /etc/resolv.conf?

what is the result of nslookup <host>

You need to check your host resolve order. That tells the machine
in what order to search the "/etc/hosts", NIS and DNS host
information and even whether to check certain name services at all.
The actual name of the file varies with OS. Under IBM AIX it is
"/etc/netsvc.conf". Under COMPAQ Tru64 UNIX it is "/etc/svc.conf".
Under SGI IRIX it is a line in the "/etc/resolv.conf" file for
versions below 6.5 and in the file "/etc/nsswitch.conf" under IRIX
6.5. Under SunOS there was no such file. Under SOLARIS it is
"/etc/nsswitch.conf". As I recall DEC ULTRIX also used
"/etc/svc.conf".

Hope this helps,
Don

Typo in your /etc/hosts file perhaps?

If you are using Solaris check the /etc/nsswitch.conf is set to use
hosts as well as any other lookup eg DNS.

Solaris, Linux, and others have something like this in their
/etc/nsswitch.conf:

hosts: nisplus dns [NOTFOUND=return] files

If you don't have the word "files" in there, it will not look at the
files at all.

Check your /etc/nsswitch.conf and read the man page on nsswitch.conf,
thats probably a good start. The default settings use NIS as a
authoritative source of information.

That's not gonna work very well on an ALPHA or an AIX.

The local hostname (from which you are trying to connect) should
be included in the file /etc/hosts.equiv on the remote host.

You must use the -l flag, to ensure you login on the remote host
with your local username. This useraccount must be known als at the
remote host.

See also the manual pages og the rlogin command.

Another thing to check for is to make certain that
the /etc/nsswitch.conf file is configured correctly.

for example:

hosts: files [NOTFOUND=continue] dns [NOTFOUND=continue] nis

in this instance, if a system is in /etc/hosts, but not in
DNS or NIS, the system will check /etc/hosts first, then DNS, then
YP in that order.

hope this helps...

One thing...I notice you put the [NOTFOUND=continue] in the line twice.
It's not needed, since this is the default action for NOTFOUND. I think
you're used to seeing [NOTFOUND=return] in the /etc/nsswitch files, but this
is only stop it going to "files" if the information is not found in a NIS
map lookup. If NIS is not running, then the default action is to go to the
next option in the line...such as files.
