Hi,

simple example table with userip and name:

Just log:

set clientip [IP::client_addr]
set tablevalue [table lookup $userip]

if {$tablevalue  != ""} {
    set name $tablevalue 
    log local0. "IP $userip - name  $name"
}

Modify or delete:

set clientip [IP::client_addr]
set tablevalue [table lookup $userip]

if {$tablevalue  != ""} {
    set name $tablevalue 
    log local0. "IP $userip - name  $name"
     delete
    table delete $userip
     then create
    table set $userip youssef 3600
}

You can also replace:

table replace   
table set $userip youssef 3600
