9/14 I have a 2-IP account from @home, with the standard setup (cable
modem to cheapo hub, hub to two boxes). I just set up samba on
my linux box to serve MP3's to roomie's win machine. IP routing
has been set up on both computers, so, hypothetically, when he
plays my mp3s, no data should go out the hub and come back in.
Furthermore, when cable modem is disconnected from hub, it still
works. However, when it's plugged in, the blinkenlichts on the
cable modem seem to indicate that something is being transmitted
in both directions, correlated with the mp3 playing. tcpdump
shows only smb packets at that rate. What am I missing?
(presumably something I don't understand about how the routing
happens?) flames >& /dev/null
\_ Write down both IP addresses, netmasks. Compare subnets.
Run traceroute to other computer's IP.
\_ my ip is 24.A.B.C while his is 24.D.E.F (A!=D, etc). @Home
recommends netmask of 255.255.255.0 however. Also, since I
have a separate route to him directly (mask
255.255.255.255) and he has the same route back, the rest
shouldn't matter, no? (the latter claim is confirmed by
traceroute, yes)
\_ You sound good then. Cable modem could be blinking
lights whenever it sees signal on the Ethernet, but
it shouldn't pick up the packets because the dest
MAC address != cable modem's MAC address.
\_ cable modem's blinkin correlates with whether or not the
mp3 is playing. i trust winamp not to be chatting covertly.
ideas?
\_ SMB, right? There are probably broadcast
control packets that the cable modem picks up.
\_ Ah. Yes. Rings a bell now. This probably covers it.
Fucking braindead protocol. |
