Unable to get the output

Hi All,

I have constructed the attached file on my GRC but i don’t see any
when i run it over terminal.

I am using
nc localhost 9001(in one terminal)

perl -e ‘print ‘a’*1024’|nc localhost 9000(on separate terminal)

i use these commands after i run my grc file.

Please tell me where am i going wrong.
