Hi Antun,
the current definition of GLOBUS_TCP_PORT_RANGE is perfectly valid;
we needed to use a space instead of a comma as separator to avoid a
problem with job submission to PBS.
If MyProxy supports GLOBUS_TCP_PORT_RANGE, it should allow for the
comma to be used.  In any case, there is an easy work-around:
define MYPROXY_TCP_PORT_RANGE with a comma as separator;
the next release will have YAIM do that standard.

Hi *,
in order to be able to retrieve credentials from the MyProxy server to an 
UI, obviously you need to have some free ports on the UI. As you may see 
from the e-mail below, the correct syntax for the GLOBUS_TCP_PORT_RANGE 
should be something like

GLOBUS_TCP_PORT_RANGE="20000,25000"

and NOT as we all have (Do we? At least I do) have in /etc/sysconfig/globus 

GLOBUS_TCP_PORT_RANGE="20000 25000"

With this (incorrect) syntax, just the port 20000 is used, and if it is 
occupied by some other process, myproxy-get-delegation fails... I have 
verified this.

However, will this change create some other problems if made on all nodes, 
i.e. does anything depend on the exact syntax

GLOBUS_TCP_PORT_RANGE="20000 25000"

and will fail if the space is replaces by the comma?

Thanks, Antun

Hello Antun,

Your syntax for GLOBUS_TCP_PORT_RANGE isn't correct.  The two port
numbers should be separated by a comma, not a space, like "20000,25000".
I think that should solve the problem.  If not, let me know.
