selecttest tool

[Jeff Lightner]

On RHEL5 with kernel 2.6.18-92.1.6.el5 the results are OK with the -r but not without (it failed at 1022 sockets without).

It makes me wonder though - does BIND (named) automatically do what the -r flag of selecttest is doing?   Does it matter whether named is running as root or a different user?  That is to say does the above test being successful with -r flag mean that I can be confident named is opening a wide range of ports?

Makes sense, especially because BIND9 does the same thing, and this
tool is primarily intended to check the behavior of BIND9.  I've
updated the tool and put the revised version at the same URL:
