Everything can be balanced between real servers not just httpd?
the services that we know to work are in the HOWTO. In principle any
single port service can be balanced by LVS.
I'am balancing DNS, smtp, pop3, http and a propietary UDP service.
Are the linux directors actually physically servers?
they are not servers. They are routers with a slightly unusual set of
rules. Clients do not connect to services on the director.
If so what server
requirements would I need for the directors?
read the performance section.
I'am using one master and one backup. The servers are PIV 2,8 Ghz 512 MB
memory. With this I'am balancing 3 UDP servers, 2 HTTP servers, 2 POP3,
2 smtp and 2 DNS servers.
The connections are moderate in TCP. In UDP I have about 2500
connections per second.
What about securities, if one server gets hacked will the hacker have
access
to all servers?
quite likely. Read the security section.
Can ultramonkey accommodate third layer topology? Having a central
storage
server?
Yes
Ultramonkey is a wrapper around LVS.
