    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
