k* processes are chaff :-)...

It depends on what you use the machine for. For instance, do you use it
to serve files via FTP?

Exactly what processes do you think are superfluous ? I don't see
anything there I wouldn't expect to see ...

That said, what you expect depends entirely on what you want this
machine to do ? Is it a web server, an NFS server, Samba server etc...
Do you want ssh access or not. etc. etc.

I would suggest better than just randomly looking at processes, to look
at the services you have running and disable those you know you don't need.

I don't see anything uncommon for a server.

You could reduce the number of pop3-login processes
(login_processes_count in /etc/dovecot/dovecot.conf) if you have very
few POP3 users or the number of active consoles (ACTIVE_CONSOLES in
/etc/default/console-setup) if you don't need 6 consoles.

But as your machine doesn't seem to be busy and most RAM is unused (or
used for file caching) I don't see much reason for that.

Mark, Brian, thanks for the replies! I guess I was thinking that the
processes that started with k had something to do with a gui that had
been installed without my knowledge.
A little rtfm would have been in order before I posted, eh? ;-)
Thanks again, I'll not fix it if it's not broken!

makes it easier to view/read via the terminal. Do you know of a way to
get that to pipe to a text file?

A simple pstree usually works for me:

$ pstree -pah|more

or you can pipe it to a text file to view:

$ pstree -pah > pstree.txt
$ gedit pstree.txt

As Brian says, one person's wheat is another's chaff, but as near as I can
tell, since you have pop3-login tasks under dovecot, you _are_ running a
mail server and so the only unnecessary tasks you have are at least 5 of
the 6 gettys - those are the consoles waiting for someone to login - and
possibly proftpd. Since you're accessing the server from ssh, 1 console is
probably enough (actually, one console is almost _always_ enough, but they
take so few resources). And since you're accessing the server from ssh,
you should have on-demand sftp, so if it's just you you don't really need
proftpd, and if it's others you might prefer them to use sftp anyway (more
secure).

What I use when working with developers and filing bugs:
$ ps -auxwwf > ps.txt

I learned earlier today that ps doesn't want the dash before the
options. It will work, but complains of bad syntax:
$ ps auxwwf > ps.txt

Thanks for the input Derek.

I had completely forgotten about sftp! That's a great tip. I can
uninstall ProFtpd now.

Now, here's something I may have gone about all wrong. I use FreeBSD
on my webserver, which comes with /usr/bin/mail by default. I use
that and sendmail (installed by default) to send mail in scripts, and
retrieve it from my Mac using a lightweight pop3 app called qpopper.
I don't do *any* mail outside the box.
Since 'mail' isn't installed by default, I installed mailutils, which
installed Exim4. I read a little about Exim, couldn't find a howto to
set it up as a pop server, so I installed Dovecot as a pop server
(crazy hard for me).
IIRC, sendmail wasn't difficult to set up to send local mail in
FreeBSD, so I wonder if I could use sendmail in Intrepid, and
uninstall Dovecot and Exim?
Does that make sense?

I'm sorry, this confuses me. It looks like your asking how to re-direct
to a file, but my brain grinds to a halt because:

1. who you are.

2. you answer the question yourself next paragraph down.
