ping lwIP by your PC, you can use ping command in command line ,the lwIP
will receive your request ping package and send the echo package .The code
in icmp.c (void icmp_input(struct pbuf *p, struct netif *inp)).

simhost.c? I did not find the file in the source tree.

You can find simhost.c in the repository.
./contrib/ports/unix/proj/unixsim/simhost.c


Don't know why, but I always has a connection problem with the cvs repository.

$ cvs -d:pserver:address@hidden:/sources/lwip co contrib
cvs [checkout aborted]: connect to cvs.savannah.nongnu.org(140.186.70.72):2401 f
ailed: Connection timed out

It works fine from my home, using CDMA modem with 50KBps downlink.
