Problem here:
star doesn't receive arp request from mars
or
mars doesn't receive arp replies from star.
Probably first. You also see RX and TX are 0, while the errors are 24, which
means the no packet has been transmitted over the network by mars. The 24
errors are probably the arprequests. So most reasonable problem now is a
driver problem (does ping 192.168.2.1 work on mars?).
It's subnet-zero also but I think linux ignores that....
Eric.
I try to configure RedHat 6.0 with kernel 2.2.5-15.
With the correct netmask situation is the same. Now I have at the
first host
(mars):
eth0 Link encap:Ethernet HWaddr 00:40:95:00:00:10
inet addr:192.168.2.1 Bcast:192.168.2.15
Mask:255.255.255.240
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:24 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
Interrupt:5 Base address:0x320
At the second host (star):
eth0 Link encap:10Mbps Ethernet HWaddr 00:40:95:80:01:E3
inet addr:194.247.138.97 Bcast:194.247.138.111
Mask:255.255.255.240
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:202634 errors:0 dropped:0 overruns:0
TX packets:204416 errors:23 dropped:0 overruns:0
Interrupt:10 Base address:0x320
eth0:0 Link encap:10Mbps Ethernet HWaddr 00:40:95:80:01:E3
inet addr:192.168.2.8 Bcast:192.168.2.15
Mask:255.255.255.240
UP BROADCAST RUNNING MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0
TX packets:0 errors:0 dropped:0 overruns:0
I've observed network with "tcpdump -i eth0"
1. ping from host 1(mars) to host 2(star)
18:01:39.013370 arp who-has star.accom.ru tell mars.accom.ru
100% packet loss while ping.
2. ping from host 2(star) to host 1(mars)
18:05:09.013354 arp who-has star.accom.ru tell mars.accom.ru
100% packet loss while ping.
Both hosts are connected via bnc-connector with the cable. They
reside one
near another. Local network 192.168.2.0 works OK during long period
of time
with nearly 10 hosts.
Best regards,
Irina
