I just finished installing Redhat AS 4 Update 2.

I have NIS setup and ypbind running. I have my resolv.conf setup.
I have my nsswitch.conf setup and hosts points to dns first, then
nis, then files.

When I rexec in via Hummingbird Exceed X-window I get a
"Who are you?" message.

I have tried the + in the /etc/hosts file and tried different
nsswitch.conf
settings. I brought up system-config-network and all looks ok.

When I login from another server that is in the host file, such as the
NIS server, I can su - tomyself and I switch user ok, arriving at my
/home directory.

The only way, so far, I can get past the "Who are you" message is
to put my IP address directly in /etc/hosts. What am I forgetting?
All of these rexec logins will be from Windows XP systems using
Hummingbird Exceed.

Thanks to all.

Provide reverse lookup in your DNS server.

Thanks Dave,

I double checked and the reverse was present.

Excuse my doubts, but did you remove the /etc/hosts entry for your PC and
then, on a terminal running on the Linux server execute

# getent hosts your_pc's_IP_address

On a terminal running on the Linux server did you attempt

# nslookup your_pc's_IP_address

Dave.... I hang me head in shame.

Out of all the entries in the DNS reverse mine was the only one
missing. I sorted the IP field and right there between x.x.x.159 and
x.x.x.161 was a missing 160.

Thanks for your well founded "doubts." They proved to be most
insightful.

Now I think I will quickly run through all the DNS and make sure that
Microsoft DNS checkbox under TCP/IP "Register this connection's
addressess in DNS" did not fail elsewhere.
