How To Concatenate Strings

Hi Deon,

concat (Click here) will "join each of its arguments together with spaces after trimming leading and trailing white-space from each of them.". You can just combine variables though:

set combined "$var1$var2"

Instead of using getfield twice, you could use scan once:

 
 when RULE_INIT { 
  
    set addr [IP::server_addr]  
    set addr "111.222.333.444" 
    log local0. "Original \$addr: $addr" 
  
     Scan the address for four digits separated by periods 
    scan $addr {%d.%d.%d.%d} a b c d 
  
     Take the third and fourth octets and combine them with the static first two octets. 
    set newaddr "1.1.$c.$d" 
    log local0. "scan result: $newaddr"    
 } 
 

Log output:

Rule : Original $addr: 111.222.333.444

Rule : scan result: 1.1.333.444
