The NORSAR-3D Common Shot Wavefront Tracer- Batch uses r-services to communicate with remote machines.
- Check that rsh server is installed
rpm -qa | grep -i rsh
If not installed, install it. (It is not installed with the default installation of Suse.)
- Enable xinetd
/sbin/chkconfig --list xinetd
Check that it says on for 3 to 5. If not:
/sbin/chkconfig --level 345 xinetd on
- Configure xinetd services
Set disabled = no in rexec, rlogin, rsh
These are server processes that are listening on TCP port 512, 513 and 514.
Default: Suse off, RedHat on.
- Start xinetd
Reboot the computer or start using the script /etc/rc.d/rc5.d/S*xinetd
On Suse most of this can be done in yast2 inetd. On RedHat some of this can be done in redhat-config-services.
