Relational class or tables

With datagroups and memory tables, the key must be unique. If you want to have multiple values for a key, you could combine them:

class penatly_box {
"testuser1"   "command1|command2|command3"
"testuser2"   "command2"
"testuser3"    "command1"
}

To parse these values you could use getfield:

Thanks Aaron.

 

I will read up on getfield.

Still need a bit of clarification on this.

 

 

b class test_penaltybox '{

 

"testuser1 command1"

 

"testuser1 command2"

 

"testuser2 commnad1"

 

}'

 

 

http://domain-name.com/?uid=testuser1&command=command1 should match

 

http://domain-name.com/?uid=testuser1&command=command2 should match

 

http://domain-name.com/?uid=testuser2&command=command1 should match

 

http://domain-name.com/?uid=testuser2&command=command2 should not match

 

 

 

if {[matchclass [string tolower [HTTP::uri]] contains [getfield $::bentest_penaltybox] ":" 1 ]} {

 

pool $penaltyboxpool

 

}

 

 

I can't get the syntax correct to work. Also I want to expand it so that URI contains both "1" and "2" or "testuser1" and "command1", but not if it only has one of the two.

 

 

Can getfield be applied to a class, or can it only be applied to a URI?

 

 

sorry duplicate. deleted text

 

Sorry, I was mistaken on the name value format I gave for 9.x. That was added in ~10.0 or 10.1.

If you have a data group defined as this:

class test_penaltybox {
   "testuser1 command1"
   "testuser1 command2"
   "testuser2 commnad1"
}

To look up a single string (like the UID) in the data group and get the second field you could use findclass:

log local0. [findclass testuser1 test_penaltybox " "]

Note that the data group name is test_penaltybox and should be referenced without the $:: prefix in 9.4.4+.

Or if you want to check if a uid and command combination exist, you could try this:

    if {[matchclass "[URI::query ?&[HTTP::query] &uid] [URI::query ?&[HTTP::query] &command]" equals test_penaltybox]}{
        log local0. "matched"
    } else {
        log local0. "no match"
    }

Note the workaround used for a URI::query bug which was fixed in v11:

Thanks very much! Early testing looks great. Now I just have to sort out the logic.

Hoolio.

 

I can't seem to get the "string tolower" to work with this scenario. Can you assist?

 

 

 

if {[matchclass [string tolower "[URI::query ?&[HTTP::query] &uid] [URI::query ?&[HTTP::query] &command]" ] equals test_penaltybox]}{

 

pool penaltybox-pool

 

log local0. "matched"

 

return

 

} else {

 

log local0. "no match"

 

}

That looks right to me and saves on a test box. When you say it's not working, what error or issue do you see and when (saving the rule, during runtime or just not matching)?
