Hi list,
I'm facing a little problem in that I have to backup some nodes wich are in a 
DMZ, and that our security officier that untill now allowed us to open a port 
dedicated to client-to-TSM server communication, now refuses what he considers 
as a "security hole".
I searched the archives to find a way solving this problem , and found that 
mail : http://msgs.adsm.org/cgi-bin/get/adsm0304/292.html, where Joseph Zlatko 
tells :
>  Improved firewall security without client-initiated sessions As in any other 
> software after tons of functionality the time come to security improvement. 
> Unfortunately only DMZ vulnerability is mitigated but how to deal with 
> non-servers and especially mobile users is still open. 
I tried to find some documents about that non-client initiated session feature, 
without success. Could anybody point me to a link or give me some further 
information about it, as it could be a solution for me : a firewall port could 
possibly be opened, but only if communication is initiated from server...
Thanks in advance !
Arnaud
