RE: [SSI-users] rexec setup on RedHat 9

[Vera, M. <mx...@qw...>]

I guess I wasn't clear, I meant configuring rexec between nodes. There
is not a lot out there for setting up rexec in these days of ssh :)

I installed the rsh-server-0.17-14 rpm, and changed the
/etc/xinetd.d/rexec file changing "disable =3D no"

I also added both servers 10.0.0.1 and 10.0.0.2 to /etc/hosts.equiv

Then I sent a HUP to both xinetd process on the nodes.

Now an `rexec 10.0.0.2 date` works as long as I giev a password for root
at the command prompt.

I can whip up a doc on setting rexec up for SSI on RedHat if you like,
once I get past the password prompt that is. I didnt see a specific doc
for this, and maybe you guys are shying away from these specific types
of docs.

Let me know,

Michael Vera

Michael,

The libcluster OpenSSI version of rexec() is working fine.  What you are
seeing (error -2) is rexec's failing due to ENOENT, just like exec's
fail with ENOENT when the library tries things in your $PATH and keeps
trying until it finds one that works.

Interesting to note that according to output you sent, you
are onnoding to yourself (node 1) so you don't see the successful rexec
because it turns into an exec (since it is local), which isn't logged).
