rsh fails: [WAS] pvm connection problems
Context: 2 pentium 4 boxes; freebsd 5.4 6.0 I detected that remote login via rsh doesn't work in my boxes: e.g. # rsh uffbsd uffbsd.myd.prv: Connection refused even though I've defined the trusted hosts on each box both in $HOME/.rhosts and in /etc/hosts.equiv. I've also uncommented the shell lines in /etc/inetd.conf to no avail. What should I do to enable the (mistrusted) rsh connection?

The problem is with setting up the cluster of computers which - to begin with - is made of two pentium 4 with freebsd 5.4 (host uffbsd) and 6.0 (host NbBSD). They see each other. From NbBSD: # ping uffbsd PING uffbsd.myd.prv (10.155.194.115): 56 data bytes 64 bytes from 10.155.194.115: icmp_seq=0 ttl=64 time=0.221 ms 64 bytes from 10.155.194.115: icmp_seq=1 ttl=64 time=0.193 ms But trying to setup the virtual machine pvm add NbBSD add NbBSD 0 successful HOST DTID NbBSD Duplicate host pvm conf conf 1 host, 1 data format HOST DTID ARCH SPEED DSIG NbBSD.myd.prv4 FREEBSD1000 0x00408841 pvm add uffbsd add uffbsd 0 successful HOST DTID uffbsd Can't start pvmd Auto- Diagnosing Failed Hosts... uffbsd...

Of course, in /home/victor/.rhost on uffbsd there's the required line. The same reciprocal situation happens from host uffbsd. Perhaps I'm missing something. Could you please help me?

Vittorio Do you have inetd enabled (inetd_enable=YES in /etc/rc.conf) and is it running? Actually no, but... From the standpoint of my first box, NbBSD (freebsd 6.0) I did the following steps 1) added inetd_enable=YES at the end of /etc/rc.conf 2) modified /etc/inetd. conf uncommenting the line shell stream tcp nowait root /usr/libexec/rshd rshd (I don't know if it helps, anyway!) 3) /etc/rc.d/inetd start 4) I've checked the presence of inetd via top. It existed!! 5) Under user victor there's a .rhosts file containing: uffbsd.myd.prv victor (user victor exists on the box uffbsd and uffbsd.myd.prv is also present in the box NbBSD in /etc/hosts: I can ping it!) 6) I reciprocate the same configuring steps on the other machine uffbsd.
