I've got three Linux servers, call them Lserv1, Lserv2 and Lserv3. All running SuSE SLES7 under z/VM 4.2.0,and (I thought) all identical using VCTC communications.
I'm sending commands from Lserv1 to both Lserv2 and Lserv3 using rsh (yes, I know I should use ssh, but I haven't got it working yet). As an example, I send rsh -K Lserv2 id rsh -K Lserv3 id The command to Lserv2 returns uid=0(root) gid=0(root) groups=0(root),1(bin),14(uucp),15(shadow),16(dialout),17(audio),65534(nogroup) The command to Lserv3 returns poll: protocol failure in circuit setup This latter shows the following in /var/log/messages: in.rshd[468]: refused connect from Lserv1.net.boeing.com /etc/hosts.allow, /etc/hosts.deny and /root/.rhosts are identical on all three machines. What's this "protocol failure"? What am I missing? "You do not need a parachute to skydive. You only need a parachute to skydive twice." -Motto of the Darwin Society Gordon W.
