maximum number of ip aliases

[Simon Lok <simonlok@mac.com>]

Hello,

I am trying to setup a machine with a large number of
IP aliases bound to a single interface.  When I do this,
things seems to be happy to some extent, but sometimes
I get the message "socket: too many open file descriptors"
followed by a program quitting.  BIND in particular seems
to have this problem.

Some questions...

Is there a maximum number of aliases that one can define
to a single IP interface?  Are there kernel configuration
options that might be able to boost this?  Is there a BIND
configuration option that can "fix" this?

Thanks in advance.
