promisc mode question

promisc mode question

[Catalin Toda]

hi,

I appreciate what you guys are doing here, congratulations for your work.

My question is:
in promiscous mode for an ethernet card, why linux kernel is not 
accepting frames (packets ) that have other mac address diffrent from 
one that is on the card ( or set with ifconfig ). Accepting meaning that 
it can be used in a tcp connection. Anyway after many changes in sysctl 
I see the station is responding to icmp request, even to udp requests, 
but not on tcp ones.

For example:

I have 2 computers in same VLAN, one having the ip address 10.1.0.1 -> 
fatbastard eth1 ( default gw - is not that important) and other one 
10.1.7.101 -> oil eth2 - HWaddr 00:08:54:39:51:AC ( netmask 255.255.0.0 ).
I run those commands:

[root@oil root]# ifconfig eth2 promisc
fatbastard:~# arp -s 10.1.7.101 00:11:22:33:44:55
fatbastard:~# ping 10.1.7.101
PING 10.1.7.101 (10.1.7.101): 56 data bytes
64 bytes from 10.1.7.101: icmp_seq=0 ttl=64 time=1.8 ms

If thru to connect thru udp from fatbastard to oil it is working.
Now:

fatbastard:~#  telnet 10.1.7.101 22
Trying 10.1.7.101...
telnet: Unable to connect to remote host: Connection timed out

in the same time on oil:
[root@oil root]# tcpdump -nei eth2 port 22
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth2, link-type EN10MB (Ethernet), capture size 96 bytes

The strange thing is that I have also an dvb card (skystar2), and if on 
this card I set promisc flag all packets are accepted by the kernel even 
tcp ones.

Can you tell me what can I do that oil to accept tcp packets which have 
destination mac address diffrent from the one on the card ( changing mac 
address is not a solution) ?

I already commented this but without any effect
[root@oil root]# cat /usr/src/linux-2.6.12.5/net/ipv4/ip_input.c | grep 
OTHERHOST -A1
//      if (skb->pkt_type == PACKET_OTHERHOST)
//              goto drop;

(now I am using 2.6.12.5 kernel).
