Re: [Simple-evcorr-users] Defining a Map for Data - SOLVED
David,
You are correct, sir!
Per the inline documentation:
# if SIGHUP has arrived, reopen input files and logfile, re-read
# configuration and empty all lists concerning events and correlation
# information; *if SIGABRT has arrived, behave like SIGHUP but preserve *
* # contexts that are active*
Mon Oct 24 12:45:52 2011: SIGHUP received: full restart of SEC
Mon Oct 24 12:45:52 2011: Reading configuration from /etc/sec/cisco/asa.sec
Mon Oct 24 12:45:52 2011: 21 rules loaded from /etc/sec/cisco/asa.sec
Mon Oct 24 12:45:52 2011: Creating SEC internal context 'SEC_INTERNAL_EVENT'
Mon Oct 24 12:45:52 2011: Creating SEC internal event 'SEC_RESTART'
Mon Oct 24 12:45:52 2011: Deleting SEC internal context 'SEC_INTERNAL_EVENT'
Mon Oct 24 12:57:09 2011: SIGABRT received: soft restart of SEC
Mon Oct 24 12:57:09 2011: Creating SEC internal context 'SEC_INTERNAL_EVENT'
Mon Oct 24 12:57:09 2011: Creating SEC internal event 'SEC_SOFTRESTART'
Mon Oct 24 12:57:09 2011: Deleting SEC internal context 'SEC_INTERNAL_EVENT'
A safer reload the hashes, without losing the contexts, is to send a KILL
$pid -ABRT after editing the file.
type=Single
desc=Dynamically reload Hashes
ptype=SubStr
continue=TakeNext
pattern=SEC_SOFT**RESTART
context=SEC_INTERNAL_EVENT
action=eval %a ( open(FILE, ") { chomp; my ($key, $val) = split /=/; $hash{"$key"} = $val;
})
Or, if feeling adventurous, it's merely a .pl file. We can always
roll-your-own SIG handler. :)

demand for specialized networking skills is growing even more rapidly.

From here, you can do what you want with %host as normal.
(P.S. - David, since a reload will reload the hashes, does that count as
completing the extra credit? Do contexts persist a 'kill $PID -HUP'?)
I am thinking that they are lost on a -HUP because the -HUP recompiles the
rules.
I am thinking that you need something along the lines of
type=Single
desc=Load hashes at startup
ptype=SubStr
continue=TakeNext
pattern=reload friendlynames.txt file
action=eval %a ( open(FILE, ") { chomp; my ($key, $val) = split /=/; $hash{"$key"} =
$val; })
since you run things on reload, you probably need the clearing of the hash
in your original version as well (since this file is something that
usually only grows, the fact that a reload would not remove an entry from
the hash is probably not a big problem, but in other contexts it will
matter)
