matchclass error message
I'm using 9.4.5 build 1049.10 and trying to get a lookup against a data group that contains md5 hashes of full paths to web destinations, but I need some help understanding what the error I'm seeing means.
Here is the class and the rule:
class hashbl {
"917c33c037b3b699521d9b10c0260cd9"
"fd3d307363655c14f49102a582bc2950"
}
when HTTP_REQUEST {
set string [string tolower [HTTP::host]][string tolower [HTTP::uri]]
log local0. "$string"
binary scan [ md5 $string ] H* hexhash
log local0. "$hexhash"
if { [matchclass $hexhash equals $::hashbl ] } {
}
else {
}
}
when I apply the rule to the virtual and test it, I get the following error in the logs:
Jul 31 13:51:00 tmm tmm[1775]: Rule blacklist-hash-uribl : slashdot.org/

- I found my bonehead error - SOL1020 lists reserved words that can't be used in bigip configs... and "hash" is one of them, so my class named hashbl wasn't recognized as a class; once I changed the class name everything worked fine.
