Re: CA Express Map Network Drive over Internet

[thomas@xxxxxxxxxxx]

Has anybody out there investigated the implications of these IBM documents? I'd 
be nervous about these settings without a few additional precautions, and even 
then I'd wonder.

1) With those ports open, I'd want the traffic restricted to the iSeries IP 
address, not allowing traffic to/from any other servers in my network. (Seems 
odd restricting to the iSeries rather than the other way around.)
2) You'd want a Netserver 'guest' profile and definite restrictions on what was 
shared.
3) I figure access to Netserver would have to be either by IP address or an 
entry in the remote LMHOSTS file, rather than by Netserver system name.

Are those paranoid? Or are they not yet restrictive enough? It's right at the 
fringe of my knowledge.
