Re: Outgoing mail filters

i use mailscanner (www.mailscanner.info i think). very easy to set up.
it supports most major virusscanners as well as a few anti-spam
solutions (spamassassin is what i use, works well too).

Hi Urgrue,

You use this for filtering outgoing mail? Maybe I'm just going blind
looking at this screen too much, but I can't find anything on their site
about filtering outgoing mail.

Cheers.

Re: Outgoing mail filters

hi,
yes it works for outgoing also. this because im not running mailscanner
in procmail (which is how most people set up their mail scanners), but
like this:
/usr/sbin/sendmail -bd -ODeliveryMode=queueonly -OQueueDirectory=/var/
spool/mqueue.in
/usr/sbin/sendmail -q15m -om
/opt/mailscanner/bin/check_mailscanner

so you see, one instance of sendmail spools my mail to mailscanner's
dir (mqueue.in), mailscanner goes through that dir continuously, scans
the contents, and moves scanned files to sendmails real queue dir, and
the second instance of sendmail sends from there.
thus, since i use the same server for sending and receiving mail,
incoming and outgoing mail are all the same

the beauty of it is, these startup commands are the totality of the
configuration required to get it working with sendmail. you dont have
to lay a finger on procmailrc, sendmail.cf, or anything else.

What is it you do need to know? Are you going to be adminestering this

I don't believe that you can become even remotely competent in any
aspect of computing (whether programming, administration, or even just
usage) based solely or primarily upon academic tuition; there is just
too much to learn.

If you don't know where to start, a course may help to provide useful
orientation. But the bulk of the knowledge inevitably has to be
acquired by other means; primarily through a mixture of reading and
practice.

If the only Linux box available is the server, and you can't practice
on that, other alternatives include:

1. Using a bootable Linux distribution (e.g. Knoppix) to practice on
what is normally a Windows box, without needing to interfere with the
Windows setup.

2. Getting another box; apart from some of the desktop components,
most current Linux distributions will work fine on the computers which
are normally considered obselete (e.g. P90s, maybe even 486s; the kind
of systems which tend to be thrown away because their second-hand
value is so close to zero).

3. Using other Unix-like systems, e.g. MacOSX, or a Windows box with
Cygwin installed. Cygwin has a few "quirks", due to having to run on
top of a decidedly non-Unix OS, but most of the utilities are exactly
the same programs which form the core of any Linux distribution.

Slightly OT: Taking Unix/Linux class?

I'd like to get opinions on possibly taking a linux/unix course. We run a
Red Hat 9 linux server in a small business, and I come from a primarily
windows environment (though I do use a little Unix on Mac OS X). I was
debating taking a unix/linux course at a local community college. We also
own "Red Hat Linux Networking and System Administration", but obviously I
need the time to read this book. I don't have the luxury of playing with our
server to learn and get hands-on feel.

So based on this course description...is it worth it? How in-depth do
community college courses of this nature go? Is there another, perhaps
better way to go about learning what I need to know?

Re: Slightly OT: Taking Unix/Linux class?

Well, I'd like to chime in without the rantings of the 'haughty linux
wizards'. Eve, the course sounds likes it will point you in the right
direction. And some people need courses as a basis to get them started in
the the learning process. The course description of topics to be covered
seems to be a good foundation and progression, but as suggested earlier
make sure you play around alot. Somehow get a spare machine (even an old
clunker) and put RedHat on it. If you have access to a bunch of spare
machine, use them all. I wouldn't recommend dual booting a machine since
I garuntee you'll be blowing up you OS on the quest for knowledge several
times along the way.

Someone earlier suggested Knoppix and I'd recommend against that
suggestion. Knoppix is Debian based and there is just enough of a
difference at the administration level between Debian and Redhat for the
beginner(as you claim to be) to get very frustrated. If you cannot get
any spare machines at all,
then your last resort is knoppix.

Learn the basics with the system you'll be using most (Redhat) and then
when the neccessary, sprout out. Play and read alot. If you get stuck,
Google can almost always help, even with the toughest of questions.
Messages boards can be useful, but be aware that there are a lot of
arrogant linux users out there. Just ignore them and listen to the good
guys.

Good luck and have fun.

.... ciao:

on "2-5-2004" "Eve Atley" writ:

: Red Hat 9 linux server in a small business ... We also own "Red Hat
: Linux Networking and System Administration" ... I don't have the luxury
: of playing with our server

it is unclear to me, 'why' you want to 'learn' linux. if it's work
related, you have a problem. RH, in an M$-esque move, no longer offers
distributions like they did in the past. RH has gotten expensive.
also, RH almost always 'back-ported' security patches, and in so doing,
kept the 'user' tied to them.
in addition, if your work environ does not allow adequate time to get
the job done, then you're walking into a situation where you have
ultimate responsibility, and "NO" authority. trying to 'learn' on a
"production" machine is not a prudent choice in any event, and is not a
good career move.

it's my opinion, linux not taught, but learned. if you're serious,
you'll put a system together, and suffer the learning curve involved.
initially, you can expect to break something, and then you get to fix it.

fwiw:

(a) RTFM (read the fucking manual)
(b) 'man man'
(c) 'apropos foobar' a very helpful information template ...

Re: Slightly OT: Taking Unix/Linux class?

Having taught courses, I'd say that you could find them useful, especially
if you have a good instructor. The course should give you some directed
hands-on experience with a live system, teach you some stuff you hadn't
considered and hopefully even disabuse you of some bad practices.

On the other hand, do NOT presume that the course will turn you into
an overnight guru. Time energy and, as someone else pointed out, "Just
Playing Around" are what you need for something like that.

Some suggestions:
1: get yourself a machine (home or work) that you can play with. It
doesn't have to be an expensive new box. An old P3/500 with a 10Meg
hard drive is a fine start. If you want to play with networking get
a couple more .. A couple of P2s with 64 meg of ram will do OK. With
that and a KVM switch, you're ready to play.

If you get the hardware second hand (or out of an old store room), it'll
probably be a good bit less expensive than the course, and will give you
a leg up during the course and after (before, even).

man man is your friend

RE: Slightly OT: Taking Unix/Linux class?

I recently spent nearly 4000 dirhams on a course that following a highly
structured and very attractive syllabus. It looked very impressive, but I
spent more time teaching them than the other way. Didn't bother finishing
the course, money non-refundable. All gone, plus my time down the toilet. I
still think courses can be valuable (considering that I have taught many
much), but you must get references from knowledgable people who have taken
the course before.

And get a box to play with ;-)

Aleksander
