I have two virtually identical Solaris 10 systems, george and ringo.
Why am I getting a hang almost every single time I try to use rcp?
As root on ringo, I try things like:
rcp /.profile george:/tmp/.profile
or
rcp george:/.profile /tmp/.profile
Which files are not important. Flag -p doesn't help.
Neither does prefixing 'root@' to the host name (didn't think it would).

Once in a rare while it seems to work. But mostly hangs indefinitely.
On the other hand, I can easily use rsh, for example I can do
rsh george 'cat /.profile'
or anything else with rsh.

I know the "r" commands are looked on with disfavor.
I am not looking for an alternate solution. I must understand why this
fails.
Do not explain to me why I should not use rcp. I know.
This is a deployment script in a classroom training environment,
in a private intranet, no security consideration.

I noticed it first using the 'system' command in perl 5.8.4,
but confirmed it over and over at a bash command line.

Thanks for any help ASAP. I'm a week behind in this project already.

P.S.:
I used to do this with no trouble on Solaris 8 and 9.
I am not as familiar with Solaris 10, but I am aware that
playing with /etc/inetd.conf is not good, and so I left it alone
and didn't mess with the service parameters
('svcprop rlogin' output at end of this msg)
-------------
Both systems listed in each other's hosts file.
Wide open rhosts permission: /.rhosts on both systems contain:

Ethernet mtu was 1500, but was suggested to try 8000 by editing
/kernel/drv/e1000g.conf, but didn't help much.
