Segmentation fault

[leebestleehj]

Hi ;
   I'm sorry to bother you.
   When i use the busybox1.2.2 to ping and telnet some host ,i always see Segmentation fault;
I want to know what happened.Then i trace the code into the create_icmp_socket.c[22].
  proto = getprotobyname("icmp"); caused the error. I fand that it didn't protocols in the etc.
but i copy the /etc/protocols to my ramdisk.i also meet it? i don't know? Someone help me.
Other cmd is right!
 
# ping 192.168.0.175
