Ping question

a5an0 · 05-08-2005, 09:42 PM

Hey all. back again. I'm trying to use the -I option with ping (It lets you set the source address of the packets), but everytime I get the following:

bind: Cannot assign requested address

Does anyone have any ideas for a solution/workaround? Thanks a LOT in advance!

the "-I" option allows you to specify which IP address or interface you are sending the ping from. This means that if you have IP addresses: 192.168.1.1, 192.168.2.1, and 192.168.3.1 you could send a ping to a host from a specific address. Example I want to ping 192.168.1.100 from 192.168.1.1:

Code:

ping -I 192.168.1.1 192.168.1.100

If you just use the command "ping -I 192.168.1.100" you will get "bind: Cannot assign requested address"

why would you want to ping from a different machine than the one you are currently on?

ANd this is allowed?? if i am on machine 192.168.1.2, i can ping from 192.168.1.3 to another machine????

indeed it is. Well, the good news is I think I found a workaround: I'm crafting custom ICMP packets at the socket level in Python. It works, but I'd love to know why PING wouldnt work. Anyone?

in the source IP address try some other address same as that of ur network
