Logmail - sending syslogs by mail

uranellus

I'd like to share logmail-0.3:

CHANGES:
logmail-0.3 - 2007-05-02 23:30
added auth mechs: plain, pop3 before smtp
specify the minumum account of logs before sending
moved all the configs to $config['syslog']['logmail']

I've basically added some auth options which NEEDS to be tested!

I've supplied the added/modified scripts a long with a patch. I hope supplying the complete files makes it easier for you to have a look at my work, or maybe you'd even give it a try :)

The complete archive is available here: ~~http://alexanderschaber.de/ablage/logmail-0.3.tar.gz~~ Check below for newer version!

Have fun, and I'm looking forward for your reply :)

Looking good! When will you be ready to commit these to -HEAD and RELENG_1? RELENG_1_2 is frozen so we cannot consider adding it here.

Wow thanks for the quick answer :)

I still need to do some testing on the auth mechs (or: I need someone to test it) .. Other than that, it works great for me :)
I'll have my pfSense box in production next week, then I'll be able to do some real testing (currently just a vm) .. So I'd say that in a week or two the initial version should be ready.

sullrich

Sounds good. I'll issue you a commit bit when you are ready.

Maybe I'm jumping in a bit late here, but maybe it would make more sense to have a logging alerts tab or something, and just make the email alerts say that there's a new log alert, with a URL to the webGUI of the pfsense box it came from? Then it's as secure as your webGUI, and avoids the mess of encrypting emails.

If email encryption is the preferred way to go, personally I much prefer S/MIME. Have a field where I can put in my public key on pfsense, and then my MUA would automatically decrypt it since it has my private key.

Nice idea, I might add that as well later .. Though my initial goal was it to have the actual logs on my mail account, so I hope you don't mind, if I go for that functionality first.

Ok, that's another way to do it, though since pfSense has it's own private key for https, I guess I'll rather just use that, instead of adding another key, but I'm open to this as well if there are more people who would prefer this. Or then I might even implement both..

Release: logmail-0.4:


CHANGELOG:
logmail 0.4 - 2007-05-04 13:40 CEST
  fixed bug:            that offsets of last leftoff are written,
                        although mail was not sent since the amount
                        of collected logs is less than the specified
                        minimum log count.
  fixed problems:       with cronjob, which caused the script to stop
                        without notice and without ever actually sending
                        mail -> surpressing output of the script
                        (piping to /dev/null)
  changed input type:   password input is now actually an input type
                        password
  changed default:      the minimum count for logs is now 50 ..
  Note:                 this is the first version that actually works
                        like a charm on our production pfSense box :)

Though still need somebody to test auth mechanisms ..

Release: logmail-0.5:


CHANGELOG:
logmail 0.5 - 2007-05-05 13:40 CEST
  added enhancement:    select timeinterval for cron job
  added checkbox:       now possible to select wether logmail should
                        wait for a minimum number of new logs before sending
                        or just send without counting ..
  added some cosmetics: button onclick: show auth options,
                        hide/show of minlogcnt with checkbox
                        onenable - logmail - after a js:confirm() popup
                        some nice recomended values are loaded
  changed cron handling:cronjob is now added to $config['cron']['item']
                        and automatically added to crontab with
                        configure_cron(); this should make the cronjob
                        survive a reboot :)
                        also removing a cronjob adjusted to fit the above
                        mentioned changes.
  changed clog exec:    clog is now called with complete path to make sure it
                        works eventhough PATH might not be set correctly
  Note:                 auth mech: pop3 before smtp has been tested and
                        confirmed as working by summat, thanks :)

Some embedded or low-profile hardware around to test the cpu/memory load?

Summat tested on p3-500 and 192mb ram .. the first run was quiet a ressource hog (2 mb mail) but later ones didn't create any problem ..

GeekGod: I guess I'll be done at the end of next week .. Check the todo list in the first post ..

You're the one doing the work, do it however suits you. :)

I think both would be the way to go (eventually). Not a lot of people use S/MIME, though I think a large number of the people who want this would configure it just for this purpose because it's so convenient. All the emails would show in your MUA as normal messages, but be secure in transit.
