Re: [lwip-devel] contrib tcpip ipv6

[Edgard Lima]

Now got at a least a 'hit' on ./simhost side, but no html response.

please look bellow the print generated by -d (debug) option when I run curl

$ curl   -6 -g http://[fe80:0000:0000:0000:0302:03ff:fe04:0506%2517]/
curl: (7) couldn't connect to host at fe80:0000:0000:0000:0302:03ff:fe04:0506:80

$ sudo ./simhost -d
netif: added interface tp IP addr 192.168.0.2 netmask 255.255.255.0 gw
192.168.0.1
netif: setting default interface tp
ipv6=fe80:0000:0000:0000:0302:03ff:fe04:0506

... after run curl ...
