netsed
 

Im trying to get netsed working on open-wrt, im trying
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 10000
netsed tcp 10000 0 0 s/Hello/bbbbb
but this is what i get:
OpenWrt:~# /root/netsed tcp 10000 0 0 s/Hello/bbbbb
netsed 1.00b by Julien VdG
based on 0.01c from Michal Zalewski
Parsing rule s/Hello/bbbbb...
[+] Loaded 1 rule...
getaddrinfo(): Name or service not known
[-] Error: Impossible to resolve remote address or port.
netsed: exiting.
What am i doing wrong?
Thanks
