Someone knows if on XP Professional it's possible to force that ip
traffic, originated from different users contemporanely acive (fast
user switch is active), has different ip addresses, maybe forcing the
physical output interface even if it isn't a must.
Probably it's a little strange request and I'm not pretty sure that it
is really possible (pheraphs in theory...) but I thinked to ask to
someone with better knowledge than me before to surrender to evidence.

Thanks.
Best Regards,
Simone Navari
 
Re: Different IP for different users

TCP/IP settings are system wide for all users. XP Professional supports
Policies so you might be able to create either a policy or logon script to
manually assign an IP Address for specific users.

IP addresses are set on a operating-system basis, not on a user basis. If
you change the machine's IP address while logged on as user X then the
session run by user Y will switch to that same address.

Thank you for your answer: I suspected this, I asked it for a precise
confirm. The concept is clear: IP settings are system wide; but if I
have one network device with two ip address or, to avoid confusion,
two distinct devices on the same machine each with its IP assigned by
system, isn't possible to force a user to use only one of the two
network interfaces ? For linux I've found some clues that is possible:
I've readed that the traffic to one or more network interface, that
come from a specific user, can be disabled using iptables. Can this
help me and is it available also on XP?
If I tell you why I need this pheraps you or someone else can help me
better. I need to guarantee bandwidthto administrator account giving
low priorities to other users. My router has a bandwidth manager that
allows me to guarantee bandwidth to specific IP addresses and/or
ports: but it can't do it as I need if on the high priority pc,
administrator and other users are logged, consuming bandwidth.


Thank you again,
Best Regards.
Simone Navari.

Yes, you can enable/disable network adapters on a user by user basis, e.g.
by inserting an appropriate command into the logon script. However, if you
have users logged on at the same time then each of them will get the adapter
that is currently enabled.
