i did snip some out as i choose to keep them...

i can obviously dust all the rpc**** stuff and portmap for now correct???

can anyone please comment on the rest of these please? i mean, what is some
of this unrecognizable stuff??... at least for me eh?

this is a straight dns server with all ext3 and a swap and is running bind,
vsftpd, sshd, and smtp and that is about it.

ive done enough research and searching to be more dangerous than good on
these..........and even though i have been involved in this for a long time,
i would rather be safe than sorry with the newer opsys versions.

thanks in advance!
