Add iperf in rc.local, so it will run when system starts up

For example, if iperf is installed in /opt/iperf, add this line in /etc/rc.local

 /opt/iperf/bin/iperf -s -p 15001 >& /var/log/iperf.log < /dev/null &

To start iperf without restarting the system, run the iperf command manually /opt/iperf/bin/iperf -s -p 15001 >& /var/log/iperf.log < /dev/null &

VDT - Globus and Globus-WS Cache http://vdt.cs.wisc.edu/releases/1.10.1/installation_select.html

By default, GRIS not enabled. If you wish to run Grid Information Services (GRIS), which uses the Lightweight Directory Access Protocol (LDAP), then once you have installed your LDAP certificate you should start gris (ldapd) by doing

# vdt-control --enable gris
# vdt-control --on gris
# /etc/rc.d/init.d/gris start


GLOBUS_TCP_PORT_RANGE=40000,41000

Application users

Set environmental variable

$ GLOBUS_TCP_PORT_RANGE=40000,41000 $ export GLOBUS_TCP_PORT_RANGE


Site admins

Open ports in site firewalls

If your site has a open firewall (all ports > 1024 are open), nothing need to be done. Otherwise, make sure that the port# range 40000-41000 is open. [edit] If your globus is installed via VDT

   * Disable the Globus gatekeeper and gsiftp. (Note, this will not stop running gatekeepers or job managers.) 

vdt-control --off globus-gatekeeper vdt-control --off gsiftp

   * Edit $VDT_LOCATION/etc/services/xinetd-globus-gatekeeper and $VDT_LOCATION/etc/services/xinetd-gsiftp. 


If there is already a line with "env =...", then add the line below immediately below it:

   env += GLOBUS_TCP_PORT_RANGE=40000,41000

Otherwise, add the line below the "user =..." line:

   env = GLOBUS_TCP_PORT_RANGE=40000,41000
   * Re-enable the Globus gatekeeper and gsiftp 

vdt-control --on globus-gatekeeper vdt-control --on gsiftp


If your globus is NOT installed via VDT

   * /etc/xinetd.d/globus-gatekeeper and /etc/xinetd.d/gsiftp. 


If there is already a line with "env =...", then add the line below immediately below it:

   env += GLOBUS_TCP_PORT_RANGE=40000,41000

Otherwise, add the line below the "user =..." line:

   env = GLOBUS_TCP_PORT_RANGE=40000,41000
   * Restart the xinetd 

/etc/init.d/xinetd restart
