[wellylug] Meeting idea

[Klenner, Colin]

Thanks Don,
With the ability to connect to the Internet at the venue we could actually
follow through on what you tell us at the venue and we could share the
experience (and inevitable error messages) and collectively gain from it
anyway. 

All
The intention of the group meeting is not about showing people up either
way, but to share experiences and knowledge gleaned along the way. 
SO let's join in!

Colin

Sendmail is often installed by default (eg Red Hat, FreeBSD), youll probably
find it listening on port 25 ( netstat -na | egrep '25\>.+LISTEN' ), then
you just need to edit some of the config files like
/etc/mail/local-host-names 9used to be sendmail.cw) and
/etc/mail/relay-domains to tell the box what domains its happy to accept
mail for and relay mail for, then you need to make a .db file for the config
files that use db files like so: 
/usr/sbin/makemap -v hash /etc/mail/access < /etc/mail/access 
then you need to stop and restart sendmail, 
cat /var/run/sendmail.pid
kill the process and start it again with the command on the second line of
/var/run/sendmail.pid and away you go. Webmin has a good sendmail module
which makes admin a bit easier. 

The last thing you need to do is point the mx record of any domain you wish
to accept mail for, you need to send this request to whoever looks after
your zone file, if thats you and you run bind* its a line like this:
      IN      MX      5 mailhost.domain.net.nz. 
save and restart bind.
Alternately you may wish to investigate postfix, exim or qmail all worthy
replacements. All in all its not that difficult to setup sendmail and admin
sendmail, but it is a bit scary, sendmail.cf has got to be one of the most
arcane files in the world but luckly you can avoid it by using the macro
configuration file sendmail.mc. Reading the Bat book doesnt help much with
demystifying sendmail either!

I spose I could do a presentation ... Im a bit of a newbie sendmail admin
tho, wouldnt want to show myself up in front of the gurus :)

I was thinking about preparing a small presentation on using regexes, just
some general stuff on how they work and then some practical examples with
perl vim and grep sort of thing, would there be any intrest in this? (again
im a relative newbie to this stuff, but am willing to give it a go if not
much else if happening on the presentation front). If I do one it would be
April at the earliest as I want to see what the facilities are like (I would
like to use a laptop).
