Hi Guido,

The TCPCLIENTPORT is only used when the client uses PROMPTED mode
scheduling and it is only for the server to contact the client to say
that there is work to be done. The data comes back on the port specified
by TCPPORT.

We, like you, are trying to backup clients that are on the other side of
the firewall. Our security guys want to know a little more detail about
how the sessions are established.

Can anyone give any more detail that what is found in the standard
documentation regarding what TCP ports are used, what difference
scheduled vs prompted mode scheduling makes, etc?


Thanks,

Trevor

        We try to backup an ADSM-Client in a customer net connected over
a
        firewall. We used the option TCPCLIENTPort in dsm.sys.
        Therefore we would have a well known IP session (IP-Server,
Port-Server,
        IP-Client, Port-Client).
        We thought ADSM would use this session for the whole ADSM
traffic, but
        we were wrong. If we start the schedule on our client, a
temporary port
        address is used.
        Any ideas?

        Regards
        Guido
