I've been asked what kind of UNIX machine we should get for our
bastion host. I've been told by our network hardware people to size
it for a T1 rate of throughput. We have a T1 connection to the Internet
but does that really mean that the bastion host should expect
1.544 megabits per second?
I expect that the machine will be running some proxy software (I can't
be anymore specific at the moment), anonymous FTP service (read only),
httpd (probably NCSA's but this could change), and an authentication
server (not sure which one).
I would like some information about the performance of various
brands/models/configurations of UNIX machines that are used as bastion hosts.
I really have no idea what size of machine to get. Can we get away
with a PC-AT running Coherent or do we need the latest 64-bit monstrosity?
How much memory and disk? Is one brand's ethernet throughput better than
another's? Does that really matter? Etc., etc., etc.
