Re: [Condor-users] rsh error

["Christopher Jon Jursa" <cjursa@xxxxxxxxxxxx>]

Dear Diego Bello Carrono,

You mentioned in your email (in the messages below my signature) for me to
search for a /etc/hosts.equiv file.

The contents are as follows.

# Do not remove the following line, or various programs
# that require network functionality will fail.
136.142.118.106	gis10.exp.sis.pitt.edu	gis10	localhost.localdomain localhost

This is from my gis10 machine.  This file seems to allow access to itself.
Should I add a line for the other machines I want to access?

I do not have this file but I do have the following in this directory.

/etc/hosts
/etc/hosts.deny
/etc/hosts.allow

I have changed the allow to the following as per the other response to this
message.

in.rshd: 136.142.118.114/255.255.255.0
in.rlogin: 136.142.118.114/255.255.255.0

Is the /etc/hosts file the same as the /etc/hosts.equiv file you speak
about?  If so, if I want to reach gis10 (136.142.118.106) from gis18
(136.142.118.114), what do I place in gis18's /etc/hosts.allow file?

Sincerely,

Christopher Jon Jursa

     Hi,

     I am attempting to run an MPI executable and submit it through Condor.
I am
     using Fedore Core 5, mpich 1.2.4 and Condor 6.7.21.

     However, I am getting an rsh error when Condor executes.

     The errror message is at
     http://gis.sis.pitt.edu/temp/chris/mpi2/mpiTest.error

     The job submission file I am using is at
     http://gis.sis.pitt.edu/temp/chris/mpi/mpi_job

     Finally, the script file used in the job file is at
     http://gis.sis.pitt.edu/temp/chris/mpi2/jobfile.sh

     How is rsh used by Condor and MPI?  How do I fix the rsh error?  I
think I
     have dropped all the firewalls.  What are common reasons for this
error?

     Cheers,

     Chris

You have to configure RSH, by default, it is disabled in Linux.
Check the /etc/xinetd.d/rsh and /etc/xinetd.d/rlogin and make sure
they say disable=no.

In /etc/hosts.allow you need an entry like this:
in.rshd: 192.168.1.0/255.255.255.0
in.rlogind: 192.168.1.0/255.255.255.0

Also, you have to add every mpi host in the /etc/hosts.equiv file so
you can freely use rsh between them.

Be carefull, rsh is a plain text comunication service, so if you are
not in a closed cluster, try using ssh instead rsh.

I hope this helps.

Bye!
